-omoumm aohm U Q om moz ONOE 2m? zwom U U 3 M w k zwwi BACKGROUND OF THE INVENTION This invention relates generally to recording/repro ducing apparatus and in particular is directed to a control'system for a recording/reproducing apparatus such as, perhaps most suitably, that which is commonly known as a tape recorder. It is to be understood, however, that by the term recording/reproducing apparatus" as used herein and in the appended claims is meant any apparatus capable of performing recording and/or reproducing operation, unless otherwise noted specifically.
' Generally, the control systems of tape recorders are composed of relays and associated contacts, and for insulation purposes a low supply voltage is usually employed to operate low voltage relays. The relays coils are thus required to carry a current of relatively high value. As a consequence, the contacts are highly susceptible to sparking and to resulting damage; and the sparks can further be converted intoclicks -via the amplifier of the tape recorder. It has therefore been almost impossible to expect highly reliable performance from the prior art control systems for tape recorders and like recording/reproducing apparatus.
SUMMARY OF THE INVENTION In view of the noted deficiencies of the prior art, .it is an object of this invention to provide a control system for a recording/reproducing apparatus whichoperates in a highly reliable manner with small voltage and current values, so that the possibility of sparking is sub stantially eliminated.
2 Thus, upon closure of a desired control switch for some operation of the apparatus, -the"adjacent bias terminal is grounded therethrough to -introduce the ground potential to theset terminal of thecorresponding.flip-flop circuit and hence to trigger the same,
thereby causing the apparatus to initiate the desired operation. This operation can be terminated by closing 3 the stop which because then the flip-flop circuit is thereby reset. Further, upon closure of the pause switch during forward recording operation, the flip-flopcircuit for the forward motion of the record medium is reset whereas the flip-flop circuit for recording operation is held in a set condition, so that the apparatus will immediately resume the forward recording operation when the switch for the forward motion of the record medium is succeedingly closed.
The features which are believed to be novel and characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its configuration and mode of operation, together with the further objects and advantages thereof, will be best understood from the following description taken in conjunction with the accompany- Another object of the invention is to provide a control system wherein the production of any noise signals is prevented which might cause the erroneous operation of the recording/reproducing apparatus.
A further object of the invention is to provide acontrol system which permits the apparatus to be conditioned unfailingly for-its intended operation upon actuation of a desired one of several control switches of pushbutton or other type.
A further object of the invention is to provide a control system which permits the apparatus to be easily conditioned for a pause. or a standby condition for immediate initiation of recording operation.
A still further object of the invention is to provide a control system of relatively simple and inexpensive circuit configuration, such that the system can easily be incorporated in recording/reproducing apparatus of known construction.
Briefly summarized in accordance with a preferred embodiment of the invention, the control system includes a plurality of normally open control switches which are manually actuable to condition the recording/reproducing apparatus for operations such as forward playback, reverse playback, recording, pause, and stop, respectively. Of these the control switches for the forward playback, reverse playback, and recording operations of the apparatus are connected to the set terminals of their respective flip-flop circuits via bias terminals through which a positive voltage is normally held applied to the set terminals, while the control switch for stopping the operation of the apparatus is connected to the reset terminals of all the .flip-flop circuits. t i
a preferred embodiment of the invention. I
BRIEF DESCRIPTION OF THE DRAWINGS 'FIG. 1 is a schematic electrical diagram of a control DESCRIPTION OF THE PREFERRED EMBODIMENT The control system according to the invention will now be described in detail with reference to FIG. 1
which illustrates the system as adapted specifically for use with a recording/reproducing apparatus of the well known type utilizing a reelable magnetic tape as the record medium and hence usually referred to as the tape recorder. The circuitry of FIG. 1 is broadly composed of a circuit to control the forward motion of the magnetic tape, another circuit to control the reverse motion of the tape, and yet another circuit to control the recording operation of the apparatus, as hereinafter set forth in more detail. A
Seen to the left in FIG. 1 are five normally open control switches l0, l2, l4, l6 and 18 which preferably are all of pushbutton type and which can be conveniently arranged on the mounting panel of the recording/reproducing apparatus. As will be more-clearly understood from the succeeding description; the first control switch 10 is adapted to condition the apparatus for forward playback operation and is therefore hereinafter referred to as the forward playback switch." The second control switch 12 is adapted to, condition the apparatus for reverse playback operationand is hereinafter referred to as the reverse playback switch." The third control switch 14 is adapted to stop the operation of the apparatus and is hereinafter referred to as the stop switch." The fourth control switch 16 is adapted to condition the apparatus for recording operation and motion of the tape and is hereinafter referred to as the for fast winding of the tape either in its forward or reverse direction. Thus, the apparatus will be conditioned for fast forward operation when the forward playback and fast winding switches are both closed, and for fast reverse operation when the reverse playback and fast winding switches are both closed. As may have been understood from the foregoing description of the control switches, the recording/reproducing apparatus to which is directed this particular embodiment of the invention is of the known type permitting both recording and playback operations to be performed during the forward motion of the tape and playback operation only during the reverse tape motion. For the recording operation during the forward tape motion, therefore, the forward playback and recording switches and 16 must both be closed.
As may already be familiar to those in the art, the aforesaid pause is such that if the pause switch 18 is closed during recording operation, the forward motion of the tape will be suspended while the pertinent electrical circuit of the apparatus is still held ready for recording operation. Accordingly, if the forward playback switch 10 is succeedingly re-closed, the recording operation can be resumed without any substantial waste of time. It may further be noted that by the closure of both of the recording and pause switches 16 and 18, the apparatus can always be set in a pause, that is, held standing by for immediate recording operation, as will be later explained in further detail.
Referring now more specifically to FIG. 1, one of the two fixed contacts of the forward playback switch 10 is grounded, while the other fixed contact is connected, on the one hand, to a bias terminal labelled as +Vl (by which is meant that a prescribed positive voltage is impressed through this terminal upon closure of the power switch) via a resistance 20 and, on the other hand, to the input terminal b of a first flip-flop circuit generally designated by the numeral 22. Similarly, one of the fixed contacts of the reverse playback switch 12 is grounded, while the other fixed contact of this switch is connected, on the one hand, to a bias terminal +Vl via a resistance 24 and, on the other hand, to the input terminal b of a second flip-flop circuit 26.
One of the fixed contacts of the stop switch 14 is likewise grounded, while the other fixed contact of the stop switch is connected, on the one hand, to a bias terminal +Vl via a resistance 28 and, on the other hand, to the input terminals a and b of a NOR circuit 30, besides'beinggrounded via a resistance 32 and further grounded via a capacitor 34. The output termi-.
nal c of the NOR circuit is connected to the input terminal a of the first flip-flop circuit 22 via a reverse blocking diode 36, to the input terminal a of the second flip-flop circuit 26 via a diode 38, and to the reset terminal a of'a third flip-flop circuit 40 via a diode 42. 4 One of the fixed contacts of the recording switch 16 is connected via a diode 44 to the point of interconnection of the forward playback switch 10 and the first flip-flop circuit 22 and can thus be grounded via the switch 10. The other fixed contact of the recording switch 16 is connected, on the one hand, to a bias terminal +Vl via a resistance 46 and, on the other hand, to the set terminal b of the third flip-flop circuit switch is connected to a bias terminal +Vl via a resistance 48, to the input terminal b of a NOR circuit 50, and to the said one fixed contact of the recording switch 16 via a diode 52.
The first flip-flop circuit 22 is broadly composed of a NOR circuit 54 functioning as a gate and an additional pair of NOR circuits 56 and 58 functioning in combination as a flip-flop. The input terminal a of this first flip-flop circuit 22 is connected to the input terminal a of the NOR circuit 54 and to the input terminal a of the NOR circuit 56, besides being grounded via a resistance 60. The other input terminal b of the first flip-flop circuit 22 is connected to the input terminal b of the NOR circuit 54, and the output terminal c of this NOR circuit 54 is connected to the input terminal b of the NOR circuit 58. The output terminal 0 of the NOR circuit 56 is connected to the input terminal a of the NOR circuit 58, and the output terminal c of this NOR circuit 58 is connected, on the one hand, to the input terminal b of the NOR circuit 56 and, on the other hand, to the output terminal 0 of the first flip-flop circuit 22.
The second flip-flop circuit 26 is of similar configuration, comprising three NOR circuits 62, 64 and 66. The input terminal a of this second flip-flop circuit is connected to the input terminal a of the NOR circuit 62 and also to the input terminal a of the NOR circuit 64, besides being grounded via a resistance 68. Also connected to the input terminal a of the NOR circuit 64 via a diode is the output terminal 0 of the NOR circuit 54 of the first flip-flop circuit 22. The other input terminal b of the second flip-flop circuit 26 is connected to the input terminal b of the NOR circuit 62 functioning as a gate, and the output terminal 0 of this NOR circuit 62 is connected, on the one hand, to the input terminal b of the NOR circuit 66 and, on the other hand, to the input terminal a of the first flip-flop circuit 22 via a diode 72. The output terminal c of the NOR circuit 64 is connected, on the one hand, to the input terminal a of the NOR circuit 66 and, on the other hand, to the output terminal d of the second flip-flop circuit 26. Similarly, the output terminal 0 of the NOR circuit 66 is connected, on the one hand, to the input terminal b of the NOR circuit 64 and, on the other hand, to the output terminal 0 of the second flip-flop circuit 26.
Although the third flip-flop circuit 40 is illustrated in the form of blocks in FIG. 1, it is to be understood that this third flip-flop circuit is of identical configuration with the first and second flip-flop circuits 22 and 26 set forth in the foregoing. Thus, the terminals a, b, c and d of the third flip-flop circuit 40 correspond to the respective terminals a, b, c and d of the second flip-flop circuit 26.
The output terminal c of the first flip-flop circuit 22 is connected to the input terminal a of a NAND circuit 74. The output terminal 0 of the second flip-flop circuit 26 is connected, on the one hand, to the input terminals a and b of a NOR circuit 76 and, on the other hand, to
the input terminal b of the aforesaid NAND circuit 74.-
The other output terminal d of the second flip-flop circuit 26 is connected to the input terminal a of the third flip-flop circuit 40'via a diode 78.
The output terminal 0 of the NAND circuit 74 is connected to the base of the transistor in a first transistor switch circuit 80 which is serially connected to a first relay 82 and thence to a bias terminal labelled as +V2. Although not shown in the drawing, it is assumed that this firstlrelay 82 is electrically connected to the recording/reproducing apparatus in such a manner that upon energization of the first relay 82, the magnetic tape of the apparatus will be caused to travel forwardly from the feed reel to the take-up reel along its predetermined path for forward playback operation.
The output terminal of the NOR circuit 76 is likewise connected to the base of the transistor in a second transistor switch circuit 84 which is serially connected to a second relay 86 and thence to a bias terminal +V2. This second relay 86 is assumed to be electrically connected to the recording/reproducing apparatus in such a manner that upon energization of the second relay 86, the magnetic tape will be caused to travel in its reverse direction, with the reverse playback head of the apparatus activated for reverse playback operation.
The output terminal d of the third flip-flop circuit 40 is connected directly to the base of the transistor in a third transistor switch circuit 88 which is serially connected to a third relay 90 and thence to a bias terminal +V2. This third relay 90 is assumed to be electrically connected to the apparatus in such a manner that upon energization of the third relay 90, the apparatus will be conditioned for recording operation during the forward motion of its tape. The other output terminal c of the third flip-flop circuit 40 is connected to the input terminal a of the NOR circuit 50, and the output terminal 0 of this NOR circuit 50 is connected to the input terminal a of the first flip-flop circuit 22 in order to reset the same upon closure of the pause switch 18.
The operation of this preferred embodiment of the invention is described hereinbelow with particular reference to the graphs of FIG. 2, in which the letters a, b, c and d represent the respective terminals of the correspondingly noted circuit element or component shown in FIG. 1 and in which the hatched portions represent a HI level signal corresponding to the binary ONE while the unhatched portions represent a LO level signal corresponding to the binary ZERO unless otherwise noted.
When the stop switch 14 is closed to stop the operation of the recording/reproducing apparatus, with the power switch (not shown) of the apparatus held closed, a LO level signal is produced from the output terminal c of the NAND circuit 74, as seen in FIG. 2E, so that the first transistor switch circuit 80 is opened The first relay 82 is then no longer energized by the positive voltage from the bias terminal +V2, as seen in FIG. 2F, thereby preventing the forward motion of the magnetic tape. A LO level signal is likewise produced from the output terminal 0 of the NOR circuit 76, as seen in FIG. 2K, so that the second relay 86 is also deenergized as in FIG. 21. Thus the reverse motion of the tape does not take place either.
Forward Playback Upon closure of the forward playback switch 10, the input terminal b of the first flip-flop circuit 22 assumes the ground potential, that is, is supplied with a LO level signal as in FIG. 20. As a consequence, the input termi-,
the input terminal b of the NOR circuit 58 thereby causing the same to produce a LO level signal from its output terminals as in FIG. 2C. This LO level output signal from the NOR circuit 58 is delivered to the input terminal b of the NOR circuit 56, and since the input terminals a and b of the latter are then both supplied with'LO level signals, a HI level signal is produced from the output terminal 0 of this NOR circuit 56 as seen in FIG. 2B.
The L0 level signal from the output terminal c of the first flip-flop circuit 22, indicated in FIG. 2D, is delivered to the input terminal a of the NAND circuit 74, the other input terminal b of which is then supplied with a HI level signal, so that the output terminal 0 of the NAND circuit 74 produces a HI level signal as seen in FIG. 2E. The transistor in the first transistor switch circuit 80 is thereby rendered conductive to cause energization of the first relay 82 by the positive voltage supplied through its bias terminal +V2 as seen in FIG. 2F. The recording/reproducing apparatus is thus conditioned for, and caused actually to perform, the desired forward playback operation.
It is noteworthy that if the recording switch 16 is inadvertently closed by the operator during this forward playback operation, no setting signal is delivered to the third flip-flop circuit 40 because now the forward playback switch 10 is opened, so that there is no possibility of accidentally erasing the information recorded on the magnetic tape.
Reverse Playback For a shift from forward playback to reverse playback operation, either the reverse playback switch 12 may be manually closed, or the end of the tape in its forward motion may be automatically detected as by means of a sensing pole (not shown) in accordance with the prior art, with the result that the input terminal b of the second flip-flop circuit 26 assumes the ground potential or is supplied with a LO level signal as seen in FIG. 2,]. The output terminal c of the NOR circuit 62 is thus caused to produce a HI level signal, which signal is delivered, on the one hand, to the input terminal a of the first flipflop circuit 22 via the diode 72. The first flip-flop circuit 22 is thus reset instantaneously, and its output terminal 0 starts producing a HI level signal again as seen in FIG. 20.
On the other hand, the HI level output signal from the NOR circuit 62 is simultaneously delivered to the input terminal b of the NOR circuit 66 in the second flip-flop circuit 26, so that the output terminal c of this NOR circuit 66 starts producing a LO level signal as seen in FIG. 21. This L0 level output signal from the NOR circuit 66 is delivered to the input terminal b of the NOR circuit 64 thereby causing the same to produce a HI level signal from its output terminal c.
The L0 level signal from the output terminal 0 of the second flip-flop circuit 26 is delivered, on the one hand, to the input terminal b of the NAND circuit 74 and, on the other hand, to the input terminals a and b of the NOR circuit 76. Since the two input terminals of the NAND circuit 74 are supplied with the HI and LO level output signals from the first and second flip-flop circuits 22 and 26, respectively, its output terminal c produces a HI level signal as seen in FIG. 2E. The first transistor switch circuit is thus held closedas in the case of forward playback operation, so that the first relay 82 is also held energized as seen in FIG. 2F. As the LO level signal is delivered as aforesaid to the input terminals a and b of the NOR circuit 76, a HI level signal is produced from its output terminal c as seen in FIG. 2K thereby closing the second transistorswitch circuit 84. The second relay 86 is now energizedas.
Recording For a shift from reverse playback to forward recording operation, the forward playback and recording switches 10 and 16 must both be manually closed. The input terminal b of the first flip-flop circuit 22 is then supplied with a LO level signal, and the set terminal b of the third flip-flop circuit 40 is also supplied with a LO level signal. Thus, as seen in FIG. 20, the first flip-flop circuit 22 is caused to produce a LO level signal from its output terminal 0, and as seen in FIG. 2J the second flip-flop circuit 26 is caused to start producing a HI level signal from its output terminal by the signal supplied from the first flip-flop circuit 22 via the diode 70.
As a consequence, the first relay 82 is held energized while the second relay 86 becomes deenergized, as will be seen from FIGS. 2F and 2L, so that the magnetic tape is caused to run in its forward direction. Since the LO level signal is delivered as aforesaid to the set terminal b of the third flip-flop circuit 40, its output terminal d starts producing a HI level signal as seen in FIG. 2M thereby initiating conduction through the transistor in the third transistor switch circuit 88. The third relay 90 is now energized through the adjacent bias terminal +V2 as seen in FIG. 2N. With the recording/reproducing apparatus thus conditioned for recording operation, the desired information can be recorded on its magnetic tape running forwardly.
Pause A shift from forward recording operation to a pause can be accomplished-by the manual closure of the pause switch 18. The input terminal b of the NOR circuit 50 is then grounded or is supplied with a LO level signal as seen in FIG. 2O, and since now a LO level signal is being produced from the output terminal 0 of the third flip-flop circuit 40, the NOR circuit 50 produces a HI level signal from its output terminal 0. This HI level output signal from the NOR circuit 50 is delivered to the input terminal a of the first flip-flop circuit 22 thereby causing the same to produce a HI level signal from its output terminal c as seen in FIG.
2D. The first relay 82 is then deenergized as seen in FIG. 2F to condition the recording/reproducing apparatus for, a pause. However, since the third flip-flop circuit 40 has its operating condition unaffected by the closure of the pause switch 18, the third relay 90 is held energized through its bias terminal +V2 as seen in FIG. 2N, so that the apparatus is ready for immediate resumption of recording operation.
In order to set the apparatus out of the pause, the forward playback switch may be closed to introduce the ground potential to the input terminal b of the first flip-flop circuit 22 as previously mentioned. The first flip-flop circuit 22 is then caused to produce a LO level signal from its output terminal 0 as seen in FIG. 2D, and through the procedure already set forth, the first relay 82 becomes energized again to cause the magnetic tape to run forwardly. Since the third relay 90 has been held energized throughout the period of the pause, the recording operation can immediately be resumed only by the closure of the forward playback switch 10.
It is further possible according to the control system of the invention that the recording/reproducing apparatus be brought into a standby condition for immediate initiation of recording operation regardless of the operating condition the apparatus has been in. To this end the recording and pause switches 16 and 18 may both be closed. As a LO level signal is ,thus delivered to the input terminal b of the third flip-flop circuit 40, its output terminal d is caused to produce a HI level signal to initiate conduction through the transistor in the third transistor switch circuit 88 and hence to cause the third relay 90 to be energized through its bias terminal +V2. Let it now be assumed that the apparatus has been in forward playback operation. Since the NOR circuit 50 delivers its HI level output signal to the input terminal a of the first flip-flop circuit 22, a HI level signal is now produced from its output terminal 0. The forward playback operation is now suspended, and the apparatus is held standing by for immediate initiation of recording operation.
For a shift from forward recording operation to a stop, the stop switch 14 may be closed to introduce the ground potential to the input terminals a and b of the NOR circuit 30 and hence to cause the same to pro duce a HI level signal from its output terminal c. This HI level output signal from the NOR circuit 30 is delivered, on the one hand, via the diode 36 to the input terminal a of the first flip-flop circuit 22 thereby causing the same to produce a HI level signal from its output terminal 0 as seen in FIG. 2D. Upon resulting production of a LO level signal from the output terminal c of the NAND circuit 74 as seen in FIG. 2E, the first transistor switch circuit is turned off to deenergize the first relay 82. On the other hand, the HI level output signal from the NOR circuit 30 is delivered via the diode 42 to the reset terminal a of the third flip-flop circuit 40 thereby causing the same to produce a LO level signal from its output terminal d as seen in FIG. 2M. Asthe third transistor switch circuit 88 is resultantly turned off, the third relay 90 becomes also deenergized. The forward recording operation of the apparatus is thus terminated. It will be apparent that the reverse playback and other operations of'the apparatus can be stopped through an identical procedure upon closure of the stop switch 14.
Although not represented in the graphs of FIG. 2, a shift from reverse playback to forward playback operation can be effected by the simple closure of the forward playback switch 10. For, in this manner, the first flip-flop circuit 22 operates to condition the apparatus for forward playback operation, whereas the second flip-flop circuit 26 is reset to terminate its reverse playback operation.
In the. control system incorporating digital circuitry such as that herein disclosed, it is possible that upon closure of the power switch to apply the voltage to the bias terminals +Vl and +V2, noise signals be generated due to the rapid voltage variations thereby setting the apparatus in some undesired operation. lt is to eliminate this defect that the resistance 32 and the c apacit or cuit 30. in this manner, the capacitor 34 isgradually charged to its full capacity through the adjacent bias terminal +Vl upon closure of the power switch, so that the input terminals a and b of the NOR circuit 30 are held supplied with LO level signals for some time after the closure of the power switch because then these input terminals are held substantially grounded via the capacitor 34. Until the capacitor 34 becomes substantially fully charged, therefore, a HI level signal is delivered from the NOR circuit 30 to the reset terminals a of the first, second and third flip-flop circuits 22, 26 and 40 to prevent the apparatus from being erroneously conditioned for forward playback, reverse playback, or recording operation. it will be apparent that the electrostatic charge which has been stored in the capacitor 34 is released via the resistance 32 when the power switch is succeedingly opened.
As may have been understood from the foregoing description of the preferred embodiment of the invention, the set terminals b of the first, second and third flip-flop circuits 22, 26 and 40 are all applied with the prescribed positive voltage when the power switch of the apparatus is closed, and each flip-flop circuit is triggered when the control switch associated therewith is succeedingly closed to introduce the ground potential to its set terminal. It is possible in this manner to minimize the possibility of the apparatus being erroneously conditioned for any undesired operation due to the production of noise signals.
While the various objects of this invention, either explicitly stated or otherwise set forth, are believed to be fully accomplished by the preferred embodiment herein disclosed, it is also to be well noted that the invention itself is not to be restricted by the exact showing of the drawings or the description thereof. For
example, the control switches may be of other than pushbutton type, and the outputs of the flip-flop circuits may be connected directly to their respective relays or equivalent means, instead of providing the gates and transistor switch circuits therebetween as shown in H0. 1. It is further understood that the control system of this invention is applicable to apparatus of various types other than that herein described, such for example as that permitting both forward and reverse recording operations in addition to forward and reverse playback operations.
Thus, a latitude of modification, substitution and change is intended in the foregoing disclosure, so that it is appropriate that the invention be construed broadly and in a manner consistent with the fair meaning and proper scope of the following claims.

IPCA, Actavis in tie-up
IPCA Labs, the Mumbai-based manufacturer of bulk drugs and formulations, is tying up with Actavis of Iceland, one of the world’s top low-cost producers of medicines, reports Suprotip Ghosh.
business Updated: Sep 11, 2007 22:45 IST
IPCA Labs, the Mumbai-based manufacturer of bulk drugs and formulations, is tying up with Actavis of Iceland, one of the world’s top low-cost producers of medicines. The tie-up would include supply agreement for Atenolol and Metformin, two bulk drugs.
“We are currently working on the modalities with Actavis, and we are close to finishing the formalities,” Prem Godha, managing director, IPCA Labs, said. He, however, did not divulge the size of the deal. The company is also setting up a formulations plant in Sikkim.
Atenolol is a drug for cardiac disorders, and Metformin is used in making drugs for diabetes.
The IPCA Labs clocked sales of Rs 921.24 crore during 2006-07, and posted a net profit of Rs 122.23 crore, according to the company’s annual report. It had a market cap of Rs 1,708 crore after Tuesday’s end of trade.
The tie-up is similar in nature to the IPCA’s earlier tie-up with Ranbaxy Laboratories. IPCA produces and supplies a number of drugs to Ranbaxy as part of the deal, and Ranbaxy markets the finished dosage forms.
The company is looking at acquiring Indian plants to manufacture bulk actives, or substances that form the basic raw material for most drugs.

Amazon.co.uk: Customer Reviews: Ronhill Women's Aspiration Windlite Jacket
5.0 out of 5 stars Ronhill Women's Sports Jacket, 6 Aug 2012
By Miss Tomlinson "AuroraLeigh" (Lincolnshire, UK) - See all my reviews
This review is from: Ronhill Women's Aspiration Windlite Jacket (Sports Apparel)
I have to admit I didn't get this for running. I got it for work as it's a two mile walk with a 4kg laptop bag on my back so I wanted something lightweight that would be comfortable in the cool mornings yet breathable in the warmer afternoons (tested July 2012). So here are my thoughts:FIT: I got the size 10 (I'm 5'3" and a size 10 in normal clothing) and it's a nice fit with plenty of room for manoeuvrability.QUALITY: Well made with great lightweight fabric with a sturdy zip on the front, stiff enough so it doesn't flap when walking/running. Around the inner collar is a very thin fleece material for extra comfort when zipped up fully. It's made of ActiveLite fabric which according to the blurb makes it wind resistant but breathable which I would definitley agree with. It's so lightweight you bearly notice it's on. It also has DWR, Durable Water Repellent, though I haven't been rained on so I can't say whether it works but I see no reason why it wouldn't.ADDITIONALS: It has a small security pocket, 13cm x 13cm approx, to the bottom left with a zip for keys/inhalers/mp3 players though it would get jiggled around a bit if you're running. The jacket also claims to be reflective but I've never worn it at night so couldn't really comment. However purple isn't really a reflective colour and the small silver reflective strips are too small to be of any use, especially the ones on the back if you're carrying a backpack. It is compatible with Ronhill Vizion LEDs if you have them. It also has a pull cord around the bottom.CARE: Machine washable at 40 degrees, can be tumbled dryed and ironed if necessary. Can't be dry cleaned.In closing the only thing I would be concerned about is if you're wearing it at night, not sure it would be reflective enough. Having said that it's a very good lightweight jacket for walking/running, it's a very nice shade of purple and looks great on and delivers on almost everything.NB I payed �20 approx, though prices fluctuate all the time.
4.0 out of 5 stars jacket, 28 Oct 2012
I like this Jacket, very light weight easy to pack away, so far has kept me dry in a down pour.I've worn it on warmer days and is easily wraperable around the waist I got a size 14 but could have gone a size smaller.Its a bit lacking in high viz. the sleeves are long but I like that if not wearing gloves. the only down side is the lack of pockets . there's a deepish one inside to stuff hat or gloves. The ONE pocket with zip on the outside is barely big enough to stash a tissue in and I prefer two pockets.There is a drawstring at the sides . And also some velcro on back not sure what that is for !A nice running jacket

Businessman who gave Ukip £1m arrested and slapped with official police warning over harassment of female worker | Daily Mail Online
Police confirm he was 'issued with a harassment notice and words of advice'
Published: 10:54 EDT, 19 October 2014 | Updated: 11:37 EDT, 19 October 2014
When Ms Featherby complained to police she was dismissed from insurance company GoSkippy — linked to Banks's firm Brightside.
War over immigration: Top Tory vents fury at European Union... Top Tory claims disabled people are hard workers 'because... The generation poorer than their parents: Wages for... Thousands of patients are failing to get their cancer...
The insurance tycoon planned to give Nigel Farage's party £100,000 - but upped the donation after William Hague called him a 'nobody'
He announced he was handing the party £1million to fight the next election - because he was angry at being called a 'nobody' by William Hague.
Mr Banks, who has previously given tens of thousands of pounds to the Conservatives, said he was only going to give Nigel Farage's party £100,000 - but decided to increase it by £900,000 after Mr Hague's jibe.
The revelations over Mr Banks come after Ukip's first elected MP Douglas Carswell took up his seat in the House of Commons last week
Nigel Farage has been campaigning hard in Rochester and Strood with former Tory MP Mark Reckless ahead of next month's by-election
The announcement, timed to disrupt David Cameron's set-piece party conference speech, came after the Tories were left stunned by the double defection of rebel backbenchers Douglas Carswell and Mr Reckless.
Mr Banks — who has split from his Russian wife — told The Sun on Sunday: ‘After events all got very heated she made these allegations against me. It was agreed mutually with the police that I wouldn't contact her again.
A Ukip spokeswoman said: ‘He's done nothing illegal.’

The Ballad of Lucy Whipple by Karen Cushman, Paperback | Barnes & Noble
Read an Excerpt Chapter One Summer 1849In which I come to California, fall down a hill, and vow to be miserable here"Mama," I said, "that gold you claimed is lying in the fields around here must be hidden by all the lizards, dead leaves, and mule droppings, for I can't see a thing worth picking up and taking home." I did not say it out loud, but I sorely wanted to, for I was sad, mad, and feeling bad. The rocking wagon had upset my stomach, my bottom hurt from bouncing on the wooden seat, and my head ached from too much sun and too much emotion.It was a hot day in late August, and nothing was moving in the heat but the flies, when our wagon pulled out of the woods and stopped at the edge of the ravine. Dense evergreens towered above us, the hillsides so dark with them the mountains seemed almost black, while over all the fierce yellow sun burned in the blue bowl of the sky. All was silent, with an impression of immensity. Later, folks would call it majestic, noble, imposing, magnificent. But not me."Awful," I said, climbing out of the wagon. "Just awful." And I thought with longing of snug spaces, of tree limbs that touched the ground and enclosed safe places within, of the big chair in Gramma Whipple's parlor cozy with the curtains pulled around, of the solidity of Grampop's strong arms and rock walls and houses with porches."California Morning Whipple, quit your mooning and come here and help me," Mama called, so I wiped my sunburned face with the back of my hand and went to help.We woke up the little ones and they, along with themule and the loaded wagon, were pushed and pulled down the narrow ravine path to the bottom. Sierra, being only two, fell once or twice, so Butte, acting grown-up now he was ten, put her on his shoulders and continued pulling back on the wagon so it didn't move too fast. I fell too, but since there was no one to help me, I brushed the dust off my apron and took to skittering down again with Sweetheart, the mule, beside me.Finally, in a burst, we skidded, down the last feet of the trail to a stop. Everyone, including Sweetheart, was hot and sweaty and dirty. Everyone, especially Sweetheart, was tired and hungry and glad to be done.Mama and I stood and looked at the settlement along the river. The air, heavy with heat and dust, burned my nose and stung my eyes."Oh, my, look at this place, California," Mama said. I looked. The ground was sunburned and barren except for patches of scrub here and there. Small tents, shacks, and brush-covered lean-tos huddled along one bank of the river. On the dirt path that served as the only street, several large, tattered tents shifted in the wind. The biggest had sulune paintedacross its front  saloon, I figured spelled wrong but people seemed to have gotten the meaning allright judging from the noise inside. The hot wind howled; the tents flapped and creaked; thick dust mixed with the smoke from a hundred cook fires, tinted red by the setting sun. Surely Hell was not far away.I took Mama's hand. We'd go home now, of course. How disappointed she must be.Mama and Pa had long dreamed of goingwest, even to naming, their family for western places: me, the first, California Morning Whipple; then Butte, Prairie, Sierra, Golden Promise, the lost baby ocean, and Rocky Flat, the dog. When Pa and Golden died of pneumonia the autumn of 1848, people told Mama, "You got to stop dreaming, Arvella, settle down, and take care of them kids." But Mama was not one to listen to what she didn't want to hear  mule stubborn, her own pa used to call her. After grieving for a spell over what was lost, she took a deep breath and started to look toward what was to come. Butte, Prairie, and Sierra were caught up in her excitement, but for weeks I lived in fear of what Mama would do, for our small Massachusetts town fitted her like a shoe two sizes too small. At night I had dreams of fierce storms that blew us to desert islands, of whirlwinds and whirlpools, of great sea monsters that swallowed the whole Whipple family, including Rocky Flat.Mama had no patience with what she called my wobblies. She sold the house and stable and feed store, gave the dog to Harold Thatcher at the mill, packed us up like barrels of lard, and in the spring took us on a ship with raggedy sails to seek our fortune in the goldfields of California.When we arrived near broke in the mud and garbage that was the Bay of San Francisco,, Minnie Oates, who had come from Connecticut to fetch her husband, said, "Face facts, Arvella. My hogs lived better than this. You best come back east with us."But Mama wasn't going back. We lived on that idle ship for eight more days, its captain and crew having, abandoned it for the goldfields, while Mama stalked through San Francisco in her black dress, new flowered hat on her head and a copy of The Emigrant's Guide to the Gold Mines (25 cents, 12 1/2 cents without the map) tucked in her reticule, talking to everyone who would talk back and finally getting herself a job running a boarding house in a mining town. We took a steamer to Sacramento and then to Marysville, where she bundled up us kids in a wagon, bargained a shopkeeper her copper pot from Gramma Whipple for a mule, and trudged three days through country jagged with hills and mountains, peaks and valleys, blazing sunshine and cold sharp nights.All along the way I watched for the gold lying on the ground, the fruit hanging from the trees, the magical possibilities that Mama said awaited us in California. I saw nothing but evergreens, dirt, and sun  hardly even another human being except for some Indian women grinding acorns by the side of the road. They looked up as we passed, and their tattooed faces frightened me so that I spent the rest of the journey under my old sunflower quilt, crying for my pa and my home and all that was dear to me.
