Pierre LeBrun (4:02 PM)
Puck season is upon us folks ! Welcome to the jungle, baby, time for our first puck chat of the year !Let's get it on
Ryan (Reynoldsburg,Ohio)
your take on the Columbus bluse jackets this year
Pierre LeBrun (4:03 PM)
Don't think they will make the playoffs. West is too tough. Bounceback year from Mason obviously big x-factor there.
Pierre (So Cal)
Love the name, but hate the Sharks projection? What is the rationale for having them lose out to the kings for the top spot in the pacific, but then coming from the 4 or 5 spot to win the stanley cup?
Pierre LeBrun (4:09 PM)
As I said last year, I'm picking the Sharks every year until they win or I retire. It's become my calling card. Don't over analyze it :)
Pierre LeBrun (4:10 PM)
Hey folks sorry for the delay, had to interview new Habs captain Brian Gionta for a blog. You've got my undivided attention now !
mike (Reno)
Hey Pierre,Tell me why this year's Detroit team is any different then last years Detroit team that didnt come on until the end and then was quickly dispatched by the sharks in the second round?
Pierre LeBrun (4:11 PM)
I like the Wings to win the Central Division. I think more than anything they're rested. Like Pittsburgh, I think those two teams going to back-to-back Cup finals was mentally and physically taxing. I think the Wings are back with a bang
Frank (Dallas)
First & foremost I have to say I watched the Terry Fox 30for30 doc
Pierre LeBrun (4:12 PM)
Great stuff. We Canadians are mighty proud of both Terry Fox and Steve Nash. But it's nice to see Terry's story now get more publicity south of the border
Dave (Hamilton, Ontario)
How do you think the North East division will shake down? Is Montreal in trouble because of their D? Can Toronto work it's way into 3rd or 4th?
Pierre LeBrun (4:13 PM)
My Northeast divisional preview will be posted Friday on ESPN.com/nhl :)
John Richardson (Mimico, Ontario)
Simple question Pierre: based on what you've seen in the -pre-season, are the Leafs going to make the playoffs? I have my doubts but I'm just a gloomy Leafs fan.
Pierre LeBrun (4:13 PM)
Leafs have improved but I think they'll come up just short
david (maryland)
What one slepper team in the Eastern and Western Conference could make the playoffs this season?
Pierre LeBrun (4:14 PM)
Sleeper team in East: CarolinaSleeper team in West: St. Louis
Dave Silva (Shark Tank)
Pierre, you were recently in San Jose with the Sharks was there any news on an extension for Joe Thornton and if you had to guess right now who do you think they will name captain? Thanks keept up the great work!
Pierre LeBrun (4:15 PM)
Yeah I was there last Thursday and asked both Joe and Sharks GM Doug Wilson. Didn't get anywhere with either. Their lips were sealed. But I'd be shocked if it doesn't get done.As for Sharks captain, I'd go with Boyle, Pavelski or Thornton
Gavin (Toronto)
I bet a friend $40 that Toronto Maple Leafs forward Phil Kessel would not score 40 goals this season. Is my money safe?
Pierre LeBrun (4:15 PM)
I think he'll be around 35 goals so you might be sweating it to the end.But by the way, next time make a man's bet: $400
Bill (Tampa, FL)
Pierre, Do you see the Lightning in the playoffs? Great acquisitions on and off the ice, but to me the goaltending is a HUGE question mark.Thanks
Pierre LeBrun (4:19 PM)
Yes I think Tampa will be knocking at the door. Love what Stevie Y is doin there.listen, let's be honest about the East. After Wash, Pitt, Philly, NJ and Bos _ it's a free-for-all for the remaining three spots. I like Buffalo the most among the rest of the rest but in reality, you could easily have two or three points separate 6th from 12th this year. Parity increases with every year under this CBA.
Cory Heys (Brantford, ontario)
What do u think of an L.A. vs. Van west final, I am a huge la fan how good can the kings be this year, do u think even better without greedy pants
Pierre LeBrun (4:20 PM)
LA, Vancouver, SJ, Detroit, Chicago _ to me those five teams are most legit West contenders and it's a pick 'em between them.
Just fantasy Hocky (Toronto)
It seems that Washington already has goaltending issues. With Varly already requiring 'maintenance days', who is going to be the top dog in net there? Is Jonathan Bernier the real deal, how long before he is number 1 in LA?
Pierre LeBrun (4:22 PM)
Keep an eye on Michal Neuvirth in Wash. He was unreal in AHL playoffs last two years. Caps front office and coaching staff believe he's just as good as Varly.And yes, Bernier is real deal in LA. Quick better look over his shoulder
Mike (Mission Viejo, Ca)
Are my Kings legitimate Cup contenders this year or are they still a year or two away?
Pierre LeBrun (4:23 PM)
I'd still like to see them add a game-breaker at thet trade deadline and I know that's something they'll be looking at if their season goes as planned, given that they didn't spend the money on Kovalchuk
Chris (Vancouver)
When do you think teams will adjust thier shortcomings? Are we in for a busy first couple weeks of waivers and small trades?
Pierre LeBrun (4:24 PM)
Ya next 7 days could have some small little moves for sure
Tom (Atlanta)
Pierre,What's your take on Big Buff's move back to D for Le Thrash? Like it? Hate it? Waiting to see?
Pierre LeBrun (4:25 PM)
He actually didn't look out of place to me back there early in last spring's playoffs when Hawks used him there because Campbell was still hurt
AJ (Jersey)
How do you feel about the Pens this season? Do they have a shot to win it all again? and your thoughts on Geno moving to the wing?
Pierre LeBrun (4:25 PM)
Pens will contend as usual, no surprise there. Like the Malkin move because I think your top six should be your top six and that means Staal belongs in top six not on checking line
Matt (Phoenix)
Pierre- You ready to say it this season.. Phoenix Coyotes Western Conferance Champions!!! Obviously Bryzgalov thinks so.. You know when a small dog bark a lot but do nothing.. hahhaa that was classic
Pierre LeBrun (4:26 PM)
LOL, I really enjoyed doing that interview with Bryz. He's a quality guy. I think the Coyotes will be back in the playoffs. Great depth up front. A little worried about not replacing Michalek on back end. That might be an area of concern.
Mike Comrie (Pittsburgh)
So what do you think of my performance so far with geno? how smart do i look for coming here?
Pierre LeBrun (4:27 PM)
Your next contract will pay a lot better
don (Kansas City)
Dynasties are great, but, equal oppurntunities for all teams to compete is better. Look at Baseball, same teams in the post season with few exeptions.
Pierre LeBrun (4:29 PM)
cory (brantford, ontario)
did anything stand out watching the kings, Ive noticed during the last couple years u r starting to get on board with this team
Pierre LeBrun (4:30 PM)
Really excited about Jonathan Bernier.Also think Ponikarovsky-Handzus-Simmonds would be dynamite third line
Brian (Chicago)
Hey Pierre, who do you think will be the best goalie this season in the nhl ?
Pierre LeBrun (4:30 PM)
I'll stick with Ryan Miller. Why mess with a good thing.
Charlie [RIP Expos] (Montréal)
Hey Pierre. With post-concussion syndrome striking both Savard and Laperrière from injuries sustained from coming back too quickly, is the NHL going to implement new rules regarding head injuries? Or will team doctors simply be advised to keep concussed players out longer? Thanks :D
Pierre LeBrun (4:31 PM)
Charlie the NHL did impose a new rule regarding blindside hits to the head. It's in effect for this season.
Paul (Boston)
What playoff teams from last season don't get in this year?
Pierre LeBrun (4:32 PM)
I think Montreal and Colorado are on the bubble. Doesn't mean they won't make it back in, but they'll be in that group of teams separated 2 or 3 points from 6th to 12th in each conference.
Mark (Indianapolis, IN)
What do you think of the potential of the Zajak-Parise-Kovalchuk line that seems to be forming in New Jersey?
Pierre LeBrun (4:33 PM)
Fantasy darlings !Of course, San Jose eventually broke up Marleau-Thornton-Heatley... so we'll see how long the big boys end up together on same line in NJ
Anti Niemi (San Jose)
Pierre,I had one hell of a defense in front of me last season to help make that run, Do you see my new digs being able to do the same?
Pierre LeBrun (4:36 PM)
Well, first of all, you better make sure you get your share of starts :)I think the Sharks could use another top-four D in my opninion. Although we'll soon find out about Jason Demers cause he'll get more ice time for sure this year
Steve (CT)
Your thoughts on Tyler Ennis this year? Maybe another Tyler gets the Calder with the Sabres!
Pierre LeBrun (4:36 PM)
Yeah I mentioned him in my rookies story this week. He's a good darkhorse for it.
John (Boston)
Bruins will win 96 games, right, Pierre?!?! RIGHT!?!?! RIGHT?!?!?
Pierre LeBrun (4:37 PM)
haha, guess you need someone to cheer for since Red Sox won't be in post-season :)
Allen (Dallas)
Pierre, looking at the Kings they still seem to have a great amount of depth in the minors. Any chance that they'll try to move a couple of the young guys for a big name player?
Pierre LeBrun (4:38 PM)
YES _ If and when the Kings make a big trade this season, they'll be dangling minor-league prospects. No question.
Dan (Chicago)
Where do you think the hawks will finish this year?
Pierre LeBrun (4:38 PM)
2nd in Central, fourth or fifth in Western Conference
Jordan (Detroit)
If wings win this year, do you think the perfect human will come back for another round?
Pierre LeBrun (4:40 PM)
Geez great question regarding Lidstrom. He's been such a great guy to deal with over the years a reporters' point of view... He told me last spring that from now on he's taking it year by year with his playing career so even he couldn't your question right now
Ben (Sydney Australia)
Pierre with Mo coming back home to Detroit everyone seems content he will be a success in red and white. my question is if he fails to produce, (and we know hes capable of doing just that after a few down seasons in dallas) who do the wings turn to?
Pierre LeBrun (4:41 PM)
Hello Down Under !If Mo can't hack it maybe Abdelkader?
Shawn (Work)
Have you been to the new rink in Pittsburgh? If you have, thoughts?
Pierre LeBrun (4:41 PM)
No, Scott Burnside won't let me in Pittsburgh. He hogs all the Pittsburgh trips, including season-opener next week. But that's ok, I love my Western Conference teams....
Mark (Buffalo)
It seems that Boston is getting preference in the Northeast division. Buffalo should be better offensively than last season with the additions of Ennis and Gerbe. The addition of Niedermayer as an experienced vet and the fists of McCormick is much needed as well. On the back-end the additions of Leopold, Morrison are just as good as the loss of Tallinder and Lydman. Miller will continue to be one of the top goalies in the league.Do you feel Buffalo can beat out Boston as the top team in the Northeast?
Pierre LeBrun (4:43 PM)
Mark you know I always love giving the Sabres props. And I agree with all your points and yes, wouldn't surprise me if Sabres challenge once again for first in division. But I chose Boston because I fear Sabres got weaker on blue-line than most people think. We'll see. In any case I picked Sabres to finish second in division
John (Boston)
How productive do you see Ethan Horton being in Boston? Even with Savard iffy, he'll have a good center from the group.
Pierre LeBrun (4:43 PM)
I predict 35 goals for Horton
Brian (VA)
Hey Pierre... which PIT blueliner do you want on your fantasy team?... Martin, Goligoski, Letang?
Pierre LeBrun (4:44 PM)
Corey (NY)
What is the status of Kim Johnnson? will he play this year
Pierre LeBrun (4:45 PM)
Corey I asked his agent just now after I saw your question. he said ''status quo" which I take it means he's not ready to play yet
Pierre LeBrun (4:52 PM)
FYI I should clarify the Michal Nylander situation. He's been loaned to AHL Rochester, Florida's farm team. But I checked with both Caps and Panthers GMs and Nylanders' $3M salary still being paid by Caps. Florida only will pay him $100,000 minor-league salary
Eddie (Hoboken, NJ)
I seem to recall that Jagr, Lemieux and Stevens line did pretty good....
Pierre LeBrun (4:52 PM)
haha, and Gretzky, Kurri, Anderson?
Jim Clark (NY)
Same baseball teams in the playoffs? They have Cincinnati, Texas, San francisco, San Diego or Atlanta this year. Tampa for the second time. They have 20 teams in the LCS in the last decade..without a 16 team playoff the NHL (and NBA) have.
Pierre LeBrun (4:53 PM)
great stuff.Guess he meant Red Sox and Yanks always having $$$$. Blue Jays fans know that pain ! But Tampa showing good drafting/developing can beat Red Sox and Yanks sometimes
Stackhouse (Igloo)
Who were your favorite players growing up?
Pierre LeBrun (4:54 PM)
Guy Lafleur was by far my first hockey hero
Jason (Vickadelphia)
Did the Flyers make the right move by moving Carter to wing, he was our best faceoff guy last year
Pierre LeBrun (4:54 PM)
You can still take faceoffs even if you're a winger.
Brian G (Chicago)
Claude Giroux... breakout season????
Pierre LeBrun (4:54 PM)
Pride of Hearst, Ontario, of course !
Mike (Listowel, Ontario)
Pierre - do you see the Caps having enough in goal with the 2 young kids to get the job done given the less then defensive-minded system?
Pierre LeBrun (4:55 PM)
Funny you should ask. Was on the phone with George McPhee moments ago and we talked about his goaltending and he said he's simply not worried about it. Loves his two kids in goal.
Trent (Toronto)
What NHL has the best atmosphere in the NHL in your opinion?
Pierre LeBrun (4:57 PM)
I take it you mean NHL arena.Montreal is by far number one. Everyone around the league agrees on that. Chicago, Vancouver, Edmonton, Philadelphia, New York (MSG), Washington, San Jose also among best I've been to
Justin (Boulder, CO)
'Hawks ability to get Niemi off the salary cap books by shipping him overseas: Fair, foul, or somewhere in the middle?
Pierre LeBrun (4:58 PM)
San Jose isn't overseas my friend.But I guess you meant Huet, not Niemi :)I don't like the way teams can do that and I suspect it'll be examined in next CBA
Jason (NY)
Everywhere I read Rangers are predicted to finish close to dead last in either the Eastern Conference or the Atlantic. Are they really going to be that bad this year?
Pierre LeBrun (4:58 PM)
I don't think they'll be terrible. But I don't think they'll make the playoffs, either
Ben (Sydney Australia)
wow just got back and seen ya answered me. Gday from Oz and when do we get some hockey here?, its huge and could actually end up a major sport here. just seems we are a market the NHL refuses to notice as a possible place to make money. I honestly think its a has a better future here than in Phoenix. whats your take?
Pierre LeBrun (4:59 PM)
Ben, I covered the 2000 Olympics in Sidney. Loved my time in your country. As for the NHL, can't see players going on a 21-hour plane trip for a game
Hammer (Pittsburgh)
Have no fear.....Mr. Burnside will have to let you into Pittsburgh for the Stanley Cup finals this year. It may take awhile but you'll get here..........Primanti's is on me.
Pierre LeBrun (4:59 PM)
Well I'll be in Pittsburgh with Scotty for Winter Classic. And I'm bringing my skates
David (Florida)
How long do you think Vokoun lasts in Florida? Where do you see him being traded to as he is a highly talented goaltender on a bad team.
Pierre LeBrun (5:00 PM)
Great question David. I think if the Panthers are out of it come mid-season they'll start shopping him around.
Mike (Listowel, Ontario)
Pierre - personal interest here - you think Justin Peters will get a bunch of games this year behind Ward? Is Peters ready?
Pierre LeBrun (5:01 PM)
I spent most of camp in Western Conference cities so I haven't talked to Carolina people in a while. But my pure guess is that Cam Ward will be a work horse. Which is good because I have him on my fantasy team in the Toronto Media Hacks Hockey Pool. Did I mention I was defending champion in that pool????
Pierre LeBrun (5:01 PM)
On that note, I will bid you cats adieu. really look forward to taking your questions in these weekly chats all season long. Sorry I can't get to everyone every week, too many questions !Cheers

This invention is an improvement over the inventions covered in my US. Pats. Nos. 2,623,725, granted Dec. 30, 1952; 3,085,589, granted Apr. 16, V 1963; 3,106,937, granted Oct. 15, 1963; and 3,122,162, granted Feb. 25, 1964.
This invention relates to an improved safety valve for fluid conduits incident to operation of fluid actuated tools, distribution of gas for welding, distribution of gas for heating and chemical uses and the like, which will prevent injury to personnel, damage to equipment and loss of fluids in case of accident.
A purpose of the invention is to provide a safety valve which is substantially free of valve flutter resulting from an unequal distribution of fluid flow around the valve member.
It is an object of the invention to provide a stream lined valve member which is centrally located in a valve chamber and which will cause fluid to divide and flow equally around the circumference of the valve member.
It is another object of the invention to provide a safety valve which is spring supported and spring biased to an intermediate position within a valve chamber between opposed valve seats and which is caused to move axially relative to one of the valve seats as a result of an even distribution of fluid flow around the circumference of the valve member when a pressure dif ferential across the valve occurs.
Another object of the invention is to provide a safety valve of the aforementioned type which is equipped with be-pass means operable to effect a substantial balance of fluid pressure across the valve and restore the valve to its normal position when conditions creating a pressure differential across the valve have been rectified. Such by-pass means are manually controlled, and an important feature thereof is the provision of means for preventing an accidental discharge of fluid from the valve when the by-pass means are manually adjusted.
These and other objects, advantages and novel fea tures will be apparent from the following description and the accompanying drawings.
In the drawing:
FIG. I is an axial sectional view of the valve of the invention;
FIG. 2 is a side elevation of the valve of the invention looking from one end;
FIG. 3 is a fragmentary axial sectional view of the valve of the invention seated at the outlet end;
FIG. 4 is an axial sectional view of a modified form of the valve of the invention;
FIG. 5 is a sectional view of the modified valve form taken on line 5-5 of FIG. 4; 7
FIG. 6 is an axial sectional view showing another modified embodiment of the invention;
FIG. 7 is a cross-sectional view, taken substantially in the plane of the line 7-7 in FIG. 6;
FIG. 8 is an axial sectional view of another modified embodiment;
FIG. 9 is an enlarged, fragmentary sectional detail of a valve member equipped with a hollow supporting rod.
FIG. 10 is a fragmentary axial sectional view showing another modification.
FIG. 11 is a cross-sectional view, taken substantially in the plane ofthe line Ill-Ill in FIG. It);
FIG. 12 is an elevational view on an enlarged scale of one of the spiders used in the embodiment of FIGS. 11) and 11;
FIG. 13 is a fragmentary sectional detail of the spider;
FIG. 14 is an axial sectional view of still another modified embodiment of the valve;
FIG. 15 is a fragmentary enlarged sectional view of the valve member used in the embodiment of FIG. 14;
FIG. 16 is a fragmentary enlarged sectional view of a modified valve member;
FIG. 17 is a fragmentary enlarged sectional view of another modified valve member;
FIG. 18 is a sectional view of the valve shown in FIG. I but equipped with keeper screws at the by-pass valves thereof;
FIG. 19 is a fragmentary plan view of one of the bypass valves and keeper screws shown in FIG. 18;
FIG. 20 is a fragmentary sectional view showing one of the by-pass valves of FIG. 118 in its open position;
FIG. 21 is a sectional view of the valve shown in FIG. 6 but equipped with keeper screws at the by-pass valves thereof;
FIG. 22 is a sectional view of the valve shown in FIG. 14 but equipped with a keeper screw at the by-pass valve thereof;
FIG. 23 is a fragmentary sectional view showing the by-pass valve of FIG. 22 in its open position;
FIG. 24 is a schematic view exemplifying a hydraulic system with the valve of the invention embodied therein, the fluid flow being in one direction through the valve; and
FIG.'25 is a view similar to that in FIG. 24 but showing conditions under which the fluid flow through the valve is in the opposite direction.
In FIG. 1 l have illustrated one form of my safety valve assembly which is particularly useful in fluid conduits transporting gas where the leakage of the gas would be costly because of its economic value, or dangerous because of its hazardous characteristics to life and to property. The safety valve assembly 10 includes a valve body generally indicated by the letter B which body consists of male and female members 11 and 12 connected together by a threaded joint 13. The valve body B when members 11 and 12 are joined includes a hollow intermediate portion 14 having a cylindrical inner surface 5 and circular opposed inner end walls 16 and I7 encompassing a valve chamber C, and hollow end portions 19 and 20 on opposite sides of said intermediate portion 14. The hollow end portions 19 and 20 have corresponding first cylindrical inner surfaces 21,21 and second cylindrical inner surfaces 22,22 encompassing valve passages or ports 23 and 24. The valve chamber C and the valve passages 23 and 24 have a common axis A-A' and the diameter of the valve chamber C is greater than the diameter of the valve passages 23 and 24. A pair of opposed conical valve seats 25 and 26 are formed in the valve body B at opposite ends of the valve chamber C between the end walls 16 and 17 respectively, and the second cylindrical inner surfaces 22 and 22' respectively. The second cylindrical inner surfaces 22 and 22' are of greater diameter than the first cylindrical surfaces 21,21 thereby forming opposite annular recesses 27 and 28 respectively opening into the valve chamber C. The ends of the recesses 27 and 28 form annular shoulders 29 and 30 separating the first cylindrical inner surfaces 21,21 from the second cylindrical inner surfaces 22,22 respectively.
It will be apparent that the valve passages 23 and 24, the valve seats 25 and 26, and the valve chamber C have transverse cross sectional symmetry about the common axis A-A.
A valve V is normally positioned centrally within the valve chamber C and is streamlined and symmetrical about the axis A,A' so that fluttering of the valve is avoided. As shown the valve V includes an intermediate disc portion 31, cylindrical land portions 32 and 33 extending from opposite ends 34 and 35 respectively of the disc portion 31', and pointed conical ends 36 and 37 on the cylindrical portions 32 and 33 respectively. The cylindrical portions 32 and 33 are of a diameter substantially equal to the diameter of the first inner walls 21,21 respectively and fit snugly therein.
A pair of cylindrical helical springs 38 and 39 are seated in the recesses 27 and 28 respectively. The spring 38 has its one end abutting the annular shoulder 29 and its other end snugly encompassing the cylindrical portion 32 of valve V and abutting the valve disc portion end face 34. The spring 39 likewise has its one end abutting the annular shoulder 29 and its other end snugly encompassing the cylindrical portion 32 of valve V and abutting the valve disc portion end face 35. The
springs 38 and 39 are of substantially equal strength and normally bias the valve V to a position intermediate thevalve seats 25 and 26. The springs 38 and 39 further provide the sole means for supporting the valve V in coaxial relationship t within the valve chamber C.
As shown in this embodiment the disc portion 31 of the valve V is of only slightly greater diameter than the cylindrical portions 32 and 33, being far removed from the axis A,A', and is of a slightly less diameter than the diameter of the inner cylindrical surface encompassing the valve chamber C so that an annular space is provided between the inner cylindrical surface 15 and the peripheral surface of the disc portion 31 which has a transverse cross sectional area substantially equal to the transverse cross sectional area of the valve passages 23 and 24. The space thus provided normally permits smooth and unrestricted flow of fluid around the valve V through the valve chamber C.
The disc portion 31 is provided with tapered annular valve faces 0,41 on opposite circumferential edges thereof to provide snug fit. The valve face 40 is substantially parallel to the valve seat 25 and to the face of the conical end 36 of the valve V. The valve face 41 is substantially parallel to the valve seat 26 and to the face of the conical end 37.
Bypass passages 44 and 45 are provided in the valve body members 11 and 12 respectively. The bypass passage 44 has an opening into the valve chamber C at one end and into the valve-passage 23 at the other end and is controlled by a manually actuated, screw threaded bypass control valve 6 threaded into bore 48 within the body member 11. The bypass passage 45 likewise has an opening into the valve chamber C at one end and into the valve passage 24 at the other end and is controlled by a manually actuated, screw threaded bypass valve 47 threaded into bore 49 within the body member 12. As shown the bypass passages 44 and 45 each include two portions arranged substantially at right angles to each other, the portions which communicatewith the valve chamber C being parallel to each other and normal to the axis of flow of fluid through the passages 23 and 24 while the portions of the bypass passages 44 and 45 which communicate with the main valve passages 23 and 24 which are oppositely disposed and in axial alignment with each other and parallel to the common axis of the main valve passages 23 and 24. O-Rings 50 and 51 provide fluid seals between the bypass valves 46 and 47 respectively and their bores 48- and 49 respectively. The screwthreaded bypass valves 46 and 47 and the bores 48 and 49 into which they are threaded have parallel axes and the heads of the screw valves 46 and 47 are arranged side by side and in close proximity to each other and are readily accessible from the exterior of the valve body.
The valve V will preferably be made of rubber or of a synthetic rubber-like material which is not susceptible to excessive corrosive action by the fluid beingcarried through the safety valve. If the fluid being transported is air or other material which can be allowed to seep into the atmosphere without danger the valve V could be made of metal since, it would not then be so important to provide a complete seal between the valve faces 40,41 and the valve seats 25,26.
As previously pointed out the valve member V is symmetrical in form about the axis A,A and on both sides of a transverse axis passing through the center of the disk portion 31. The angle of inclination of the valve faces 40 and 41 and of the conical ends of the valve V with reference to the longitudinal axis A,A' is shown as approximately 45 but may be a few degrees greater or less. As shown this slope extends from the tips of the conical ends of the valve to the flat top of the disk portion 31 and includes the tapered valve faces 40 and 41, being broken only by the flat cylindrical portions of lands 32 and 33 over which the ends of the springs 38 and 39 are fitted. By reason of this construction not only is a tight seal insured when the valve is seated in either direction, but a streamlined construction is provided in either direction whereby the fluid passing through the valve is caused to divide and flow smoothly and equally around the circumference of the valve member, thus avoiding undesirable valve flutter. Moreover, since the cylindrical shoulders or lands 32 and 33 are of only slightly less diameter than the disk portion 31 the springs alone will be enabled to support the valve without the assistance of any other means more readily than would be the case if the shoulders were located nearer the axis A,A', in which case undesirable wobbling of the valve would be likely to occur unless additional supporting means were provided. The symmetrical shoulders or lands 32 and 33 are preferably substantially more than one-half way from the axis A,A' to the flat ring or disk portion 31 of the valve in the construction shown in FIGS. 1-10.
FIG. 3 shows the valve member V with the valve face 41 snugly seated against the right hand valve seat 26 completely shutting off the flow of fluid from the valve passage 23 into the valve passage 24. Above atmospheric pressure in the valve conduit 23 will keep the valve V seated in the position shown in FIG. 3 as long as the pressure in passage 24 is atmospheric.
FIGS. 4 and 5 illustrate a modified form of the invention which is designed for use in an air line, or other fluid line where the fluid can be permitted to escape into the atmosphere in small amounts. Instead of providing bypass passages in the valve housing as in the embodiment shown in FIGS. 1-3, a'central passage 52 is provided along the longitudinal axis of the valve V. The passage 52 is preferably a small diameter, cylindrical bore coaxial with the valve V. The passage 52 will allow leakage of a small amount of fluid through the valve when the valve has been forced against one of its seats as a result of a differential pressure across the valve as would be the case when a break occurs 'in the flow line downstream from the safety valve.
In operation the safety valve assembly shown in FIGS. 1 to 3, when used to shutoff the flow of gas in a gas line in the event of a break is positioned in a gas line between a pressurized gas source and a utility device. Normally the valve member V is positioned midway between the valve seats 25 and 26 but should a break occur in the downstream side of the flow line from the safety valve, a pressure differential will develop across the valve V, which will force the valve V against the downstream valve seat. As shown in FIG. 3 the low pressure occurs in passage 24 and the high pressure occurs in passage 23. The valve V will remain in the position shown until the break in the downstream flow line is fixed and pressure is again built up in the valve passage 24 to equal the pressure in the passage 23.
The bypasses 44 and 45 are provided with manually controlled valves 46 and 47 so that an operator can selectively open one of the normally closed bypass valves 46 or 47 to permit fluid from the valve chamber C to flow around the closed valve V and build up pressure in the low pressure valve passage. Valve 47 would be opened in FIG. 3 to permit fluid to flow into passage 24 until the pressure across valve V is equalized and the valve V is returned to its normal open position by means of the springs 38 and 39. Once the valve V has been returned to its normal open position the operator again closes the bypass valves 46 and 47 so that gas would not escape through the bypass passages into the atmosphere if another break should occur in the flow line.
The valve V shown in FIG. 4 is normally positioned as shown and would be forced to seat against its valve seats located on the downstream side should a break in the downstream flow line occur. The main volume of fluid flow would be shut off by the valve V but a small amount of fluid would still flow through the central passage 52 into the downstream passage. However as long as the break in the downstream flow line remains open no pressure can build up in the downstream valve passage. When the break in the downstream flow line has been repaired, the fluid flowing through the central passage 52 will build up pressure on the downstream side of the valve V until the pressure across the valve V is equallized, at which time the valve V will be returned to its normally open position by the springs 38 and 39.
The stream lined valve V supported solely by the springs 38 and 39 is substantially flutter free because of its symmetrical slope with respect to its axis and because of its position on the common axis of the valve chamber C. The surface area of the valve V facing the path of fluid flow is uniformly distributed about the' valve axis A-A' so that the axial pressure of fluid on the valve is also uniformly distributed with respect to the valve axis. There are therefore no unequal forces tending to cant the valve V relative to its axis, and the valve will move axially into sealing engagement with one of its seats 25 or 26 when a differential pressure occurs across the valve.
The valve assembly 10 can be made more cheaply than valves of a similar type requiring guide stems and guide bearings.
Because my valve is substantially flutter free and will be caused to seat properly as a result of a differential fluid pressure across it, the operation of my improved safety valve is fully as satisfactory as valves provided with guide stems and guide bearings and even more so because frictional contact between valve stems and guide bearings are eliminated.
The parallel conical faces 36 and 37 of my valve V and the valve faces 40 and 41 on the same side of the valve are features of my valve which help to eliminate turbulence within the valve chamber and help to cause uniform distribution of fluid flow around the circumference of the valve.
Reference is now drawn to another modified embodiment of the valve shown in FIGS. 6 and 7. For most part this embodiment is the same as that inFIGS. 1-3, so corresponding reference numerals are used to identify the corresponding parts. However, this embodiment is characterized in that additional means are provided to assist the springs 38, 39 in supporting the valve member V in the chamber C. These means involve providing the outer ends of the springs 38, 39, that is, the ends thereof which project into the valve port recesses 27, 28, with integral extensions 60, the latter being directed radially inwardly and terminating in eyes or bearings 61 located on the longitudinal axis of the valve, as is best shown in FIG. 7. The eyes 61 provide bearings which slidably receive the end portions of a rod 62 which extends axially through and is secured in the valve member V. Thus, the bearings 61 coacting with the slidable rod 62, effectively guide the movement of the valve member toward and away from the valve seats and assist the springs 38, 39 in properly supporting the valve member in the chamber C. When the valve is closed, fluid may be by-passed through the by-pass means 46, 47, as in the embodiment of FIGS. 1-3.
The modified embodiment of FIGS. 8 and 9 also provides the additional supporting means for the valve member as in FIGS. 6 and 7, but in the environment of the valve of FIGS. 4 and 5 where the fluid by-pass is made through thecenter of the valve member itself. Thus, in the embodiment of FIGS. 8 and 9, the valve member supporting rod 62a is hollow so as to provide an open-ended axial passage 63 therethrough, as shown in FIG. 9. This passage establishes communication between the valve ports 23, 24 when the valve member is in either of its closed positions.
In another modified embodiment shown in FIGS. 10-13, the valve member V is also provided with a supporting rod which may be either the solid rod 62 or the hollow rod 62a, depending upon whether the fluid bypass is made through the valve body as in FIG. 6 or through the valve member as in FIG. 8. In either event, in the embodiment of FIGS. 10-13 the end portions of the rod 62 (or 62a) are slidably journalled in a pair of spiders 64 which are seated in the valve port recesses 27,28 in abutment with the. shoulders 29, 30.
As is best shown in FIGS. 12 and 13, each of the spiders 64 comprises a central, tubular bearing portion 65 and a set of radially outwardly extending arms 66. The bearing portion 65 slidably accommodates the valve member rod 62 (or 620), while the outer end portions 67 of the arms 66 are in abutment with the valve port shoulders 29,30. These end portions of the arms are provided with notches 68 for seating the ends of the springs 38,39 it being understood that in this embodiment the ends of the springs are not equipped with the bearing forming extensions 60,61, as in the embodiments of FIGS. 6-8.
FIGS. 14 and 15 illustrate another modified embodiment of the valve of the invention, wherein the valve body B consists of a pair of complemental sections 70,71 which are screw-threadedly connected together as at 72. The valve body defines a valve chamber C with coaxial valve ports 73,74 having valve seats 75,76 facing the valve chamber. The valve ports are equipped with annular shoulders 77,78 for abutment by outer ends of tapered, helical springs 79 located at the opposite sides of the valve member V, the valve member being equipped at its opposite sides with circular lands 80 on which the inner ends of the springs are seated.
To assist the springs 79 in supporting the valve member V in the chamber C, the valve member is provided with an axial rod 81, the end portions of which are slidable in bearings 82 provided on extensions 83 of the outer ends of the springs 79, as already described in connection with FIGS. 6-9.
The valve member supporting rod 81 is solid, and when the valve member engages the valve port seat 76, fluid may be by-passed from the chamber C to the valve port 74 through by-pass ducts 84,85 which are formed in the body section 71 in communication with a bore 86 with which the section 71 is also provided. As will be noted, the duct 84 opens into the chamber C, while the duct 85 opens into the valve port 74. A by-pass valve plug 87, equipped with suitable sealing rings 88, is screw-threaded into the bore 86, so as to control the flow of fluid through the bypass ducts.
The arrangement is particularly well suited for use in an explosion valve, in which the valve member V comprises a disc-like body 89 provided at its opposite sides Finally, if the valve is used only for transmission of air, the valve member of FIG. 17 may be utilized, this being simply in the form of a disc body 89b having a rounded periphery 94 for engaging either of the seats 75, 76. In such event the sealing rings 91 are omitted and the fluid by-pass 84-88 through the body section 71 also need not be provided, since the valve member supporting rod 81a may be hollow to provide a fluid bypass 95 therethrough, as already mentioned in connection with FIGS. 8 and 9.
Although the embodiment of FIG. 14, using a valve member in accordance with FIGS. 15, 16 or 17, has been shown as having the valve member rod 81 (or 81a) slidably joumalled in the bearings 82 carried by extensions 83 of the springs, 79, it is to be understood that, alternatively, the rod of the valve member may be joumalled in spiders seated in the valve ports 73,74 against the shoulders 77,78, as in the embodiment of FIGS. '10-13.
Particular reference is now drawn to FIG. 18 which shows the valve 10 of FIG. I equipped as already described with the by-passes 44, 45 and manually controlledv by-pass valves 46, 47 therein, these by-pass valves being in the form of screws threaded into the bores 48, 49 in the body of the valve. Manifestly, when either of the bypass passages 44 or 45 is to be closed, as it is during-normal operation of the valve 10, the bypass valve screw 46 or 47 is screwed-in its bore 48 or 49. Conversely, when the by-pass passage is to be opened, the by-pass valve screw is screwed-out in its bore.
It is to be particularly noted that the safety valve of the invention is mainly intended to be used with fluids which, because of their chemical and/or economic characteristics, and also because of considerablypressures under which they are transmitted, make it desirably to minimize possible leaks. The valve of the with the aforementioned spring seating lands 80. For
sealingly engaging the valve seats 75,76, the valve member body 89 is also provided with 'chamfered peripheral edges 90 and with a pair of sealing rings 91 of Neoprene, or the like. The rings 91 are seated in annular grooves 92 formed in the periphery of the body 89, the grooves being separated by an intermediate land portion 93.
If the valve is a gas valve, a modified valve member shown in FIG. 16 may be used. The body 89a of this valve member is provided with only one chamfered edge 90 and only one sealing ring 91 for coaction only with the valve seat 76 on the downstreamside of the valve. Otherwise the arrangement is the same as already explained in connection with FIG. 14.
invention serves this purpose quite well in closing off fluid transmission through the valve in the event of a pressure differential across the valve, as for example, that which may be caused by substantial leakage at some point downstream from the valve. When such leakage is corrected, the valve, for example the valve 10 of FIGS. 1 or 18, has to be reset to its normally open position, and this is done by opening the by-pass valve screw, for example the screw 47, which permits restricted flow of fluid through the by-pass passage, for example the passage 45, so that the fluid pressure across the valve is substantially balanced and the movable member of the valve returns to its centralized position.
Of course, the opening of the by-pass valve screw, for example the screw 47, is done manually by screwingout the same in its bore 49, and if this were done in an arbitrary manner, it is quite possible that the by-pass valve screw would be screwed completely out of its bore with the result that dangerous fluid under high pressure would be discharged from the valve through the by-pass passage (44 or 45) and through the bore (48 or 49), thus creating a hazardous condition which the valve itself is intended to eliminate.
Thus, to safeguard against this possibility, the invention also provides means for positively preventing the by-pass valve screws 46 and 47 from being inadvertently or accidentally removed from their respective bores 48 and 49. Such means comprise a keeper screw 95 which, as shown in FIGS. l8, l9 and 20, is threaded into the valve body at a point adjacent the bore 49. The screw 95 has an enlarged head 95a which is sufficiently large in diameter as to overlap the bore 49 to some extent, yet leaves the bore sufficiently open to permit a screw-driver to be inserted into the bore for turning the bypass valve screw 47.
When the keeper screw 95 is in position, the underside of its head 95a engages the outer surface 96 of the valve body and the length of the bore 49 in relation to the by-pass valve screw 47 is such as to permit adjustment of the screw 47 between its screwed-in position in which it closes the by-pass passage 45 and its screwedout position in which the passage 45 is open, while the screw 47 remains fully within the bore 49. In its screwed-out position, the screw 47 comes up against the underside of the keeper screw head 95a, the latter thus acting as stop means to prevent inadvertent removal of the screw 47 from the bore 49 and thereby safeguard against possible discharge of pressurized fluid through the open passage 45 and bore 49. In FIG. 18 the bypass valve screw 47 is shown in its screwed-in or closed position, while FIG. 20 shows the same in its screwed-out or open position against the underside of the keeper screw head 95a. A second keeper screw 95,
with its head 95a, is provided in 'the valve body to prevent removal of the by-pass valve screw 46 from the bore 48 in the same manner as already described.
FIG. 21 illustrates the keeper screws 95 applied to the bypass valve screws 46, 47 of the safety valve of FIG. 6, the arrangement and function of the keeper screws being the same as already explained in connection with the valve in FIGS. 18-20.
Similarly, FIGS. 22 and 23 show the keeper screw 95 on the body member 71 of the safety valve of FIG. 14, the enlarged head 95a of the keeper screw overlapping the bore 86 which contains the by-pass valve screw 87. The closed or screwed-in position of the screw 87 is shown in FIG. 22 wherein it blocks the by-pass passages 84, 85, while in FIG. 23 the passages 84, 85 are open when the screw 87 is screwed-out in the bore 86 against the underside of the keeper screw head 95a. In the instance of the valve of FIGS. 14 and 22-23 only one bypass valve screw 87 is provided at the downstream or outlet side of the valve, and thus only one keeper screw 95 is necessary.
Each of the safety valves in FIGS. ll, 6, l8 and 21 is arranged so that its valve member V is axially movable in either direction to close off a valve port at one side or the other of the valve chamber C. When the valve is installed in a line in which fluid flows in only one direction, the valve closes only in that direction, that is, in the downstream direction, as for example when a leak occurs downstream from the valve and a pressure differential is created, under which the valve closes by higher pressure from the upstream side. In this type of an installation it is necessary to provide a valve port for the valve member V only at the downstream side of the chamber C, along with the associated by-pass means at that port. However, by providing valve ports and bypass means at both sides of the chamber C, (as in the instance of the valves in FIGS. ll, 6, I8 and 21) an added benefit is obtained in that the valve may be installed in the fluid line in either direction, with assurance that one of the valve ports and bypass means llllll available at the downstream side of the valve where the valve closing action occurs.
However, the provision of the valve with valve ports and by-pass means at both sides of the chamber C is even more important and virtually necessary in installations where fluid flows through the valve selectively in either direction, one such situation being exemplified in the closed hydraulic system shown diagrammatically in FIGS. 24 and 25.
Here, for example, the safety valve I9 is installed in a hydraulic line 97 between a hydraulic cylinder 98 and a four-way control valve 99, the system also including a fluid tank I99, a pump lllll and a check valve 192, all arranged in the conventional well known manner. When the control valve 99 is in the position shown in FIG. 24, fluid flows from the pump lllll through the safety valve III in the direction of the arrow I99, thus supplying fluid to the cylinder 99 to extend the same. On the other hand, when the control valve 99 is in the position shown in FIG. 25, the cylinder 98 is retracted and fluid flows through the safety valve lltl in the direction of the arrow I94 to drain in the tank I90.
Thus, since the fluid flow through the safety valve M) is selectively in opposite directions, either of the two valve ports at the opposite sides of the valve chamber C can serve as the inlet port while the other serves as the outlet, depending on the direction of flow, and either of the two valve ports can become closed by adifferential' in fluid pressure, depending upon. which valve port is on the outlet or downstream side, where a leak may have occurred. Obviously, the arrangement also necessitates the provision of by-pass means at the ports on both sides of the safety valve, so that the valvemay be restored to its normal open position when the leak has been corrected.
It will be appreciated from the foregoing that the valve of the invention as represented by FIGS. 1, 6, l8 and 21 has what may be called double-acting characteristics resulting from the movability of the valve member V in either axial direction to close off the port at either side of the valve chamber C, in accordance with the direction of fluid flow, and further resulting from the provision of by-pass means for the valve ports at both sides of the valve chamber, to facilitate resetting of the valve member by balancing of pressure when conditions which caused closing of the valve have been corrected. As such, the provision of the two valve ports and of the two associated by-pass means at the opposite sides of the valve chamber is useful not only in permitting the safety valve to be installed reversibly in a line having uni-directional fluid flow, but what is more important is its usefulness in lines where fluid flows selectively in both direction, as already explained in connection with FIGS. 24, 25.
, It may be noted that the safety valves of FIGS. 4 and 8 are also double-acting in the sense that their valve member is movable in either axial direction to close off a port at either side of the valve chamber, but in this instance by-pass means through the valve body are not necessary inasmuch as a by-pass is provided through the valve member itself.
The invention is particularly applicable to lines carrying oxygen and dangerous gases generally such as are used in connection with cutting torches and the like wherein back pressure are likely to be generated. The
present invention will tend to prevent person injury, explosion and dangerous fires.
Further advantages of the double bypass system herein described will be apparent from the following comment which is directed to those skilled in the gas welding art. As is known to those skilled in this art all acetylene gas fittings are made with a left hand thread for connections of hoses used in burning torches. The fitting when made has a machined circle around its body signifying it is an acetylene fitting with a left hand thread.
Oxygen is used with acetylene when using a burning torch for cutting metal. The fitting for oxygen has a right hand thread, hoses generally are a twin hose, one for acetylene and one for oxygen each the same size, pressures in the hose are regulated by the user with regulator gauge at the supply.
One valve is needed for safety on the acetylene line and one valve is needed for safety on the oxygen line.
The bypass valve is made with a left hand thread for acetylene on one end of the valve with a bypass, and on the other end of the valve has a right hand thread for oxygen with a bypass. Thus a double bypass valve canbe used for either acetylene or oxygen.

Evangeline Lilly, From 'Lost' to 'Real Steel'
"Lost" star Evangeline Lilly's planned hiatus from acting will be short lived - she's signed on to co-star in Steven Spielberg's new film "Real Steel". Lilly recently stunned fans by revealing she may quit acting once the desert island drama ends this month because she's "not passionate" about her career.
But the actress has backtracked on her plans to take a break, and signed on to star in the sci-fi drama, which features Spielberg as a co-executive producer. The TV star will play a friend of Aussie hunk Hugh Jackman's character, a former boxer who teams up with his long-lost son to train a robot for a championship fight.
And she will have a familiar face on set - Lilly's "The Hurt Locker" co-star Anthony Mackie has also landed a role as a boxing promoter, reports Daily Variety. "Real Steel" is set for release in November 2011.

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet.

Dustin Pedroia experiences concussion-like symptoms after leaving game
|08.30.14 at 8:04 pm ET
ST. PETERSBURG, Fla. — Red Sox second baseman Dustin Pedroia left Saturday night's game against the Rays in the second inning after being hit in the left side of the head by a swinging elbow from Tampa Bay baserunner Logan Forsythe.
Pedroia had just gathered in the throw from center fielder Mookie Betts when he lunged to tag Forsythe, who was tagging up from first on a fly ball to deep center field. The Rays baserunner slid head first, swinging his right arm around and striking Pedroia just below his cap.
After calling time, Pedroia immediately slumped face down on the ground, leading to Red Sox manager John Farrell and trainer Brad Pearson sprinting onto the field. After a consultation with Pearson, the second baseman was led off the field.
Following the Red Sox' 7-0 loss to the Rays, Farrell said that Pedroia was experiencing concussion-like symptoms.
"The head-first slide, Pedey's coming in to try to put a quick tag on him," Farrell said. "Momentum looked like Forsythe's slide, he struck him with his elbow. That was clear. It looked like the momentum took him across the bag. He's reaching out ahead of him to try to brace himself and not slide past the bag, and as he's reaching forward he caught him with a good elbow to the left side of the head.
"He's got some symptoms that are consistent with a concussion. He's improved as the game has gone on … Not as dizzy as he was when he first came off. But we'll take every precaution necessary with Dustin."
After the game, Forsythe was adamant there was nothing intentional about the blow to the head.
"Absolutely not," he said. "I'm definitely not that kind of player, and the only move that I made was to try to swim-move the tag to get out of the way. It was a bang-bang play, and you know the way he came down, too. It was just a hard play."
Brock Holt moved over from third base, replacing Pedroia at second, with Will Middlebrooks coming in to play third.
The Red Sox trailed 3-0 at the time of Pedroia's departure.

The Swedish Government (Länsstyrelsen in Dalarnas Län) has granted Skangass permission to build and operate a new Terminal for LNG (Liquefied Natural Gas) within the harbour in Gävle, Sweden. Skangass aims at starting the construction work during 2015.
The permission is given for a storing capacity of 30 000 m3 LNG and a handling of up to 500 000 tonnes LNG each year.
The planned LNG terminal is an important part of the expansion of LNG infrastructure in Sweden and the Baltic Sea. The environmental advantages of using LNG instead of oil based fuel within shipping, industry and heavy transportation are substantial. Sulphur and particle emissions are reduced to almost zero, nitrogen oxides (NOx) emission is reduced by 85-90 per cent and the carbon dioxide (CO2) is reduced by 25 per cent.
The investment decision will probably be taken during spring 2015. The terminal will be developed in cooperation with Gävle Hamn that invests in building the infrastructure in the harbour area.

Rotten Tomatoes Data Reveals The Most Overrated And Underrated Movies
Published 12:59 pm, Saturday, May 17, 2014
A great interactive graphic highlighted on Reddit shows that critics' reviews aren't always accurate representations of popular opinion about a particular movie.
Ph.D. student Ben Moore analyzed critic and public ratings from popular review aggregate site Rotten Tomatoes.
The site assigns each movie a percentage based on the share of positive reviews it got from critics. Rotten Tomatoes also gives an "audience" rating that shows how many users rated the movie positively.
Moore looks at the difference between critic reviews and audience ratings from the site.
The most overrated movies (films reviewed positively by critics but disliked by audiences) might surprise you:

The weekend is over and stocks are falling (SPX, SPY, DJI, IXIC, USO, WTI, OIL, VDE, IWIM, TLT)
- "Spy Kids" (critics: 93%, audience: 45%)
- "3 Backyards" (critics: 76%, audience: 31%)
- "Stuart Little 2" (critics: 81%, audience: 40%)
- "Momma's Man" (critics: 91%, audience: 50%)
- "About a Boy" (critics: 93%, audience: 54%)
The kids' movies that made the list could be explained by the fact that most of the people who are rating the movies on Rotten Tomatoes probably aren't kids, and therefore not the target audience of the film.
But it's still surprising to see "Spy Kids" was so beloved by critics.
Now here's a look at the most underrated movies from Moore's analysis:
- "Facing the Giants" (critics: 13%, audience: 86%)
- "Diary of a Mad Black Woman" (critics: 16%, audience: 87%)
- "Grandma's Boy" (critics: 18%, audience: 86%)
- "Step Up" (critics: 19%, audience: 83%)
- "Because I Said So" (critics: 5%, audience: 66%)
Many of the movies that made the "most underrated" list were popular with moviegoers but not necessarily considered great cinema.

Charlize Theron's Name Given to One of Three Girls in South Africa
Actress Charlize Theron has given pregnant mums in her native South Africa some inspiration - the star's name is one of the most popular there. The "Monster" star's mega success has had such a profound impact on her home town, many families have decided to pay tribute to the actress by naming their daughter Charlize.
She tells the New York Post, "There's a baby-naming boom in my native South Africa. Parents giving their infants my name. I grew up on a farm outside Benoni, where large numbers of local girls - one out of every three - are now called Charlize."
Charlize won the Best Actress title from the Academy Award in 2003 for her portrayal of Aileen Wuornos in "Monster". Two years later, she got another nomination for her role in "North Country", but lost to Reese Witherspoon. She will next take on the part of evil queen in "Snow White and the Huntsman".

Paris Hilton Strips Naked in New Reality Show Premiere
Paris Hilton is seemingly trying to lure audience to watch her new reality show with her sex appeal. On "The World According to Paris" which was debuted on Oxygen on Wednesday, June 1, the 30-year-old blonde beauty stripped naked in front of camera in a bath scene.
The hotel heiress did not hesitate to bare her naked back as she washed her hair and soaped up in the tub of her Beverly Hills mansion. After taking a bath, she covered her body with fuchsia towel while chatting with her mother Kathy.
Also in the same episode, Paris' relationship with her boyfriend Cy Waits got a highlight. They were seen having an argument over texts with an ex of the "House of Wax" babe. They, however, managed to patch things up, with Paris saying "Cy is such a great guy I don't want to mess things up... I love him so much," and the two lovebirds later made out.
