RENO, NEVADA--(Marketwire -08/07/12)- Allied Nevada Gold Corp. ("Allied Nevada" or the "Company") (ANV.TO)(ANV)(ANV) is pleased to provide financial and operating results for the three and six months ended June 30, 2012. The results presented in this press release should be read in conjunction with the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2012, filed on SEDAR and EDGAR and posted on Allied Nevada's website at www.alliednevada.com. The financial results are based on United States GAAP (with the exception of the non-GAAP financial measure "adjusted cash costs") and are expressed in U.S. dollars.
Q2 2012 Highlights:
-- Hycroft production of 30,662 ounces of gold and 208,208 ounces of silver was in-line with Company expectations for the second quarter of 2012. Production is expected to ramp up through the second half of 2012, benefitting from mining in higher grade areas of the mine with an expected 50% increase in mined grades, the increased mining rate with the additional mining equipment, operation of the Lewis leach pad and stacking of solution. The mine is expected to produce approximately 180,000 ounces of gold in 2012. -- Adjusted cash costs(1) of $527 per ounce in the second quarter of 2012 were as expected. Hycroft has completed the stripping campaign it had planned for the first half of 2012 and expects the strip ratio to decline to below 1:1 for the remainder of the year. Also contributing to expected better unit costs are the additional large capacity haul trucks and loading equipment. With the operation of the third Hitachi EX5500 shovel, unit costs declined 15% in June. As a result of these changes, adjusted cash costs(1) per ounce is expected to decline in the second half of the year and is on track to be within the previously stated guidance range of $475-$495 per ounce. -- In May 2012, the Company issued CDN $400.0 million of uncollateralized senior notes (the "Notes") for gross proceeds of $400.4 million after the effect of the cross currency and interest rate swap. As a result of this, cash and cash equivalents at June 30, 2012, were $577.0 million. The Company is now well positioned financially to progress with the expansions at Hycroft. -- Excavation for the crushing area is complete on schedule. The construction contract for the crusher was awarded in the second quarter and the contractor is mobilizing to begin construction in mid-August. The first major components of the crushing system have begun arriving on site. -- The final EX5500 shovel arrived and was in operation in June 2012. As of today, the haul fleet currently totals 16 320-ton haul trucks and six 200-ton trucks. Equipment availability has been improving with the current market conditions and shelving of major construction and expansion projects, and the Company is taking advantage by accelerating delivery of equipment where available. Two CAT 345-ton trucks which were not originally scheduled are expected to arrive on site in the third quarter of 2012. The Board of Directors recently approved early expenditure for the three wire rope shovels for which delivery has been accelerated by an average of one year. The first is expected to be in operation in the fourth quarter of 2013, one full year ahead of original schedule. -- The public comment period for the Final EIS, which allows for expanded mining areas and construction and operation of the large north and south leach pads, is now closed. Issuance of the record of decision for the Final EIS is imminent. This will allow for mining of the current heap leach reserve and add approximately 16 million square feet of additional leach pad space which will support the heap leach operation for the current life of the mine. With this approval, permitting for the mill construction and associated infrastructure will begin immediately, as per schedule and we anticipate receipt of these approvals in the first quarter of 2013. -- In connection with the mill expansion, the Company has signed an agreement with a major batch plant concrete provider who is capable of providing all required concrete for the entire expansion project. The delivered rates for the concrete are significantly lower than those paid in late 2011 for the new truck shop. Current detailed engineering indicates that the capital required to secure the long-term power transmission and distribution is below the feasibility estimate. -- The Board of Directors recently approved the capital to secure permanent and temporary housing in Winnemucca for the construction team and increasing workforce. With this, Allied Nevada has partnered with one of Nevada's premier housing development companies, who have already taken significant steps in procuring the land and approvals needed to move forward with the project. -- Allied Nevada has significantly strengthened its owner's expansion team which is lead by Carl Consalus, Vice President, Project Development. The core project team is fully integrated with the Fluor engineering and design team. -- Revenue from sales of 17,762 gold ounces and 174,736 silver ounces in the second quarter of 2012 was $33.7 million, an increase of $0.1 million compared with 20,293 ounces of gold and 85,092 ounces of silver sold for revenue of $33.6 million in the second quarter of 2011. Revenue was higher primarily due to the higher average realized gold price of $1,609 per ounce in the second quarter of 2012 compared with $1,504 per ounce in the same period in 2011. This was partially offset by fewer ounces sold in the second quarter of 2012 as compared with the same period in 2011 as we did not have any sales from carbon and the stacking of lower grade solution onto the leach pad increased in-process inventories. To maximize efficiency of the Merrill Crowe plant, lower grade pregnant solution was recirculated through the leach pad to increase solution grade, which is expected to contribute to increased ounces of gold and silver sold for the remainder of 2012. As previously announced, the Company was unable to process and sell any of its gold and silver laden-carbon as it does not have an on-site carbon strip plant. In June 2012, the Company entered into an agreement with Yukon Nevada Gold Corp. to process its inventory of metal-laden carbon. The first shipment was received by Yukon mid-June, but they were unable to begin processing until mid-July due to minor modifications required to their plant. The Company did not receive any processed gold and silver in the second quarter and continued to stockpile metal on carbon. The Company has purchased a carbon strip vessel and expects it to be operational in the fourth quarter of this year at an anticipated capital cost of $2 million. The Company expects to be current with the sales of metal on carbon by the end of 2012. -- Allied Nevada achieved net income of $6.1 million or $0.07 per share in the second quarter of 2012, compared with $3.6 million or $0.04 per share in the second quarter of 2011. Net income in the second quarter of 2012 as compared to the same period in 2011 benefited from lower exploration, development and land holding costs which was partially offset by increased interest expense as a result of the May 2012 issuance of the Notes. -- Cash used in operating activities was $8.3 million in the second quarter of 2012, compared with cash provided by operating activities of $4.1 million in the same period in 2011 as the Company was impacted by higher inventories as the increased mining rate and solution pumping built up metal in process. -- Cash used in investing activities was $41.0 million in the second quarter of 2012 compared with $18.4 million in the same period in 2011. Investing activities in the second quarter of 2012 were primarily capital spending associated with the Hycroft mine expansion. This included amounts for the crusher and associated excavation, mine development, leach pad expansion and mill construction. -- Cash provided by financing activities was $386.2 million in the second quarter of 2012 compared with cash used in financing activities of $1.5 million for the same period in 2011. During the second quarter of 2012, the Company issued the Notes for gross proceeds of $400.4 million and paid related debt issuance costs of $13.2 million. The Company's repayments on capital lease obligations increased to $3.1 million as a result of entering into additional leases for haul trucks and shovels.
Hycroft Operations Update
Key operating statistics for the three and six months ended June 30, 2012, compared with the same period in 2011, are as follows:
Three months ended Six months ended June June 30, 30, --------------------- --------------------- 2012 2011 2012 2011 ---------- ---------- ---------- ---------- Total material mined (thousands of tons) 15,559 7,895 27,017 15,675 Ore grade - gold (oz/ton) 0.012 0.014 0.014 0.014 Ore grade - silver (oz/ton) 0.296 0.406 0.405 0.320 Ounces produced - gold 30,662 22,783 63,135 43,501 Ounces produced - silver 208,208 93,221 374,364 154,972 Ounces sold - gold 17,762 20,293 38,109 41,634 Ounces sold - silver 174,736 85,092 303,042 144,658 Average realized price - gold ($/oz) $ 1,609 $ 1,504 $ 1,666 $ 1,451 Average realized price - silver ($/oz) $ 29 $ 36 $ 31 $ 35 Average spot price - gold ($/oz) $ 1,609 $ 1,504 $ 1,651 $ 1,456 Average spot price - silver ($/oz) $ 29 $ 38 $ 31 $ 35 Total adjusted cash costs(1) (thousands) $ 9,356 $ 9,310 $ 20,161 $ 20,428 Adjusted cash costs per ounce(1) $ 527 $ 459 $ 529 $ 491
Hycroft mined 15.6 million tons of material including 4.4 million tons of ore grading 0.012 ounces per ton ("opt") gold and 0.296 opt silver that were placed on the leach pad and 0.8 million tons of mill material which was stockpiled for total ore tonnage mined of 5.2 million tons. As planned, the Company produced 30,662 ounces of gold and 208,208 ounces of silver in the second quarter of 2012 and 63,135 ounces of gold and 374,364 ounces of silver in the six months ended June 30, 2012. The variance between gold and silver production compared to ounces sold was primarily due to the Company being unable to recover metal from our carbon columns since the middle of the first quarter of 2012 and the recirculation of lower grade solution through the leach pads.
As previously announced, the Company has signed an agreement with Yukon Nevada to process it metal-laden carbon. As of June 30, 2012, no carbon had been processed. The Company was notified in mid-July that Yukon Nevada had begun processing carbon and the Company expects that the 16,331 gold ounces included in carbon at June 30, 2012, will be processed and sold by year end. Furthermore, the Company has purchased a carbon strip vessel and expects it to be operational in the fourth quarter of 2012.
The mine currently pumps 8,500 gallons per minute ("gpm") of solution to the leach pads. Given that the Merrill Crowe plant can process 5,000 gpm of pregnant solution and the carbon circuit 1,500 gpm of pregnant solution, lower grade excess pregnant solution is recirculated to the pad to increase the solution grade. This maximizes the efficiency of the processing plant by processing higher grade solution. The Company continued to stack solution during the second quarter of 2012. The stacking of solution contributed to the difference between ounces of gold and silver produced and sold. As a result of solution stacking, the solution grade increased during the first six months of 2012 and is expected to continue to increase throughout 2012. This increase in solution grade is expected to result in increased ounces sold for both gold and silver for the remainder of 2012.
The final of the three Hitachi EX5500 shovels became operational in June 2012. Eleven of the new Komatsu 320-ton trucks were in operation by the end of the second quarter and five additional have been placed into operation since the end of the second quarter. The total fleet today is comprised of 16 320-ton trucks and six 200-ton trucks. The mine has also secured two additional CAT 795 345-ton trucks that are expected to arrive on site in the third quarter which will help with construction and operating efforts.
Unit costs have improved with the addition of the larger, more efficient mining equipment as evidenced in June 2012, when unit mining costs decreased 15% from the previous month. Total tons mined increased by 35% from the first quarter 2012 to the second quarter of 2012.
The majority of construction and development efforts in the second quarter of 2012 were focused on excavation of the gyratory crusher location and completion of the 3.0 million square foot Lewis leach pad expansion. Processing of ore on the Lewis leach pad began in the second quarter.
Drilling activities at Hycroft in the second quarter of 2012 totaled 50,378 feet in 58 holes and were for engineering in support of the expansion projects at Hycroft. Drilling was primarily for facility condemnation, in-pit resource conversion, and to obtain additional material for ongoing metallurgical testing.
Exploration drilling will ramp up in the third quarter of 2012 with the first pass program commencing at Wildcat and a regional campaign beginning in the Hasbrouck area. The Company will use drilling campaign data to assess mineralized material with results expected to be announced in the first quarter of 2013.
2012 Outlook
Hycroft Operations
Production is expected to ramp up through the remainder of 2012 as the Company realizes benefits from mining higher grade areas of the mine where mined grades are expected to be 50% higher than those mined in the first half of 2012, increased ore tonnage placed on the leach pads over the last six months, increased ore under leach with the operation of the Lewis leach pad, and increased solution grades resulting from ongoing stacking. The Company expects production for 2012 to be approximately 180,000 ounces of gold.
Sales are expected to continue to differ from production due to carbon processing constraints and solution stacking to increase solution grades while managing the Merrill Crowe plant's current solution processing capacity. As discussed above, the Company signed an agreement with Yukon Nevada to process its metal-laden carbon and expects to have its own carbon strip vessel in operation in the fourth quarter of this year. Total 2012 sales are expected to be approximately 150,000 ounces of gold, with third and fourth quarter sales expected to be approximately 40,000 ounces of gold and 70,000 ounces of gold, respectively.
Adjusted cash costs(1) of $529 per ounce in the first half of 2012 were as expected. Anticipated decreases in the stripping ratio, declining unit mining costs resulting from the utilization of larger mining equipment, and increased ore tonnage being placed on the leach pad are expected to contribute to decreasing adjusted cash costs per ounce for the remainder of the year. For 2012, the Company continues to expect that the adjusted cash costs(1) per ounce will be within the previously stated guidance of $475-$495.
Major Capital Programs
Capital expenditures in 2012 are expected to total approximately $285 million. Significant capital projects include the following: ongoing condemnation and engineering drilling, permitting, progress payments for long-lead fixed and mobile equipment, engineering for the mill and gyratory crushing projects and infrastructure improvements.
The initial capital cost estimate for the Hycroft expansion project is expected to be $1.2 billion. As of June 30, 2012, Allied Nevada had spent or committed $452.4 million, which is in-line with the feasibility estimate and represents approximately 36% of the total capital estimate. All equipment pricing is firm and includes freight and taxes. In the case of the mining equipment, the pricing also includes on-site assembly and commissioning.

Non-GAAP Financial Measures
Adjusted cash costs is a non-GAAP financial measure, calculated on a per ounce of gold sold basis, and includes all direct and indirect operating cash costs related to the physical activities of producing gold, including mining, processing, third party refining expenses, on-site administrative and support costs, royalties, and mining production taxes, net of by-product revenue earned from silver sales. Adjusted cash costs provides management and investors with a further measure, in addition to conventional measures prepared in accordance with GAAP, to assess the Company's performance of the mining operations and ability to generate cash flows over multiple periods. Non-GAAP financial measures do not have any standardized meaning prescribed by GAAP and, therefore, may not be comparable to similar measures presented by other companies. Accordingly, the above measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.
The table below presents a reconciliation between non-GAAP adjusted cash costs to cost of sales (GAAP) for the three and six months ended June 30, 2012 and 2011 (in thousands, except ounces sold):

Perfect place with the perfect location
The cottage itself was well equipped and we had everything we needed for our little break. Also, the master bedroom was stunning and the bed was huge and comfy.
I would definitely like to stay here again and I feel that there was still so much left to discover all around the area.
About the Owner
We have spent 20 years enjoying this wonderful cottage. Our children, friends, family and more recently holidaymakers, have all appreciated this much loved holiday home.
Over the years we have improved Pen-y-Bryn turning it into a comfortable well equipped house. Finished with period and contemporary pieces of furniture, we have tried to compliment the existing features of a 160 year old Welsh Cottage.
Guestbook comments from the owner
"The perfect cottage for a quiet holiday in North Wales"
5 of 5 stars Reviewed November 11, 2013
The cottage is a beautifully located, very well appointed with a traditional atmosphere with wood-burner, exposed beams etc. The very attractive garden is pretty secure for children/dogs, and the surrounding countryside is perfect for cycling, fell-running and so forth. If you jump in the car all of Snowdonia's attractions are easily accessible. The nearest pub/shop are around 2 miles away which some people might find inconvenient (although we never have), and the pub is certainly worth the walk. Personally I feel this is the perfect cottage if you are looking for somewhere quiet to enjoy the Welsh countryside
"A real gem." 5 of 5 starsReviewed April 11, 2013
"We enjoyed our first visit so much, we came back to the UK for a two month stay at the cottage. The cottage is tranquil, warm and snug.

Our stay in the cottage could not have been better. The house is situated in the midst of beautiful Snowdonia hills and views from the garden were exceptional.

Rhyd Cottage
A really well appointed cottage and very comfortable. Lanes a bit narrow between cottage and main roads so be prepared to brake HARD on occasions (if you want to keep the front end of your car away from the boy-racers LOL) Ideal location for walkers.
Lovely Long Weekend
We recently stayed for 3 nights from 1st May to 4th May in this lovely cottage and had a wonderful time. We had not visited North Wales for many years and were reminded of what a beautiful area this is to visit. The cottage was very clean, comfortable and cosy with a lovely log burner for the evenings. There is a nice slate table on the terrace allowing us to sit and eat outside during nice weather.
We found there to be plenty to do in the area from visiting the lovely coastal towns of Criccieth and Abersoch to walking up to the waterfall at Croesor and the highlight of our stay visiting the beach and headland at Nefyn with the 'pub on the beach' The Ty Coch serving food and drink with a lovely relaxed atmosphere proving very popular. The pretty villages of Beddgelert and Betws y coed along with Snowdon are only a short drive as are the beaches at Borth y gest (very pretty) and Black Rock Sands which is larger and has vehicle access.
Many thanks to Pam for all her help and clear instructions.
We will be back.
The perfect break
We spent three nights at Pen-y-bryn in early March, and three of us and a dog had a perfect short break. Arrangements beforehand were clear and helpful, and the cottage is absolutely delightful - beautifully furnished, cosy log burner, nice hot water, everything we needed. The surrounding countryside is beautiful and great for walking, and it was very easy to reach the towns and seaside at Porthmadog and Criccieth. I can't think of anything negative to say - we had a great time and loved the cottage. Many thanks. (And thanks to Pam for posting on the mac we left behind!).
Idyllic Cottage for a relaxing break
This was our first visit to North Wales but I have to say Rhyd and Pen-y-Bryn was a wonderful place to start. The cottage is comfortable and the setting is so pretty. We were lucky enough to have some sunny days and sitting out on the front terrace was just so relaxing. Everything we needed was provided, the furniture was in keeping with the traditional style of a welsh cottage, my favourite room was the large bedroom with the kingsize bed, so pretty.
I felt the cottage was as expected from the website images, and as there were only 4 people in our party it felt more than large enough for all of us.
There were many lovely walks that we did straight from the cottage, but we also visited the beaches of Borth-y-Guest and Blackrock Sands, along with a train ride up Snowdon. There was so much to do and there was a good selection of tourist leaflets in the house.
Overall we had a great holiday and would love to visit again.
Many thanks
From the Owner
"The location of the village is ideal, quiet yet not too remote. Visitors are offered the 'best of both worlds' - expansive beaches, beautiful coves and dramatic mountains all blending together to create what I feel is one of the most stunning landscapes in the UK."

It is Farhan Akhtar and Farah Khan's brithday today. While Farhan is celebrating his 42nd birthday on 9 January, Farah Khan has turned 51. Considering they are both very popular in the industry, several Bollywood stars took to Twitter to wish Farhan and Farah a happy birthday.
While Farah is one of the most popular directors and choreographers of Bollywood, Farhan has proved his prowess in multiple fields including acting, direction, singing, production and writing. Farhan's latest movie "Wazir" hit screens on 8 January, which also features Amitabh Bachchan, Aditi Rao Hydari and Neil Nitin Mukesh.
On the other hand, Farah Khan's last directorial venture was Shah Rukh Khan-starrer "Happy New Year". She also worked as a choreographer in SRK-Kajol-starrer "Dilwale". Farhan and Farah, who happen to be cousins, share their birthday on the same date. While the two wished each other on Twitter, many Bollywood stars also wished the two on their special day.

EAST GARDEN CITY - Police are searching for two men who attacked and robbed a man leaving Nassau Community College.
The incident happened at around 4:15 p.m. Tuesday on the East Garden City campus.
According to police, two men approached the 20-year-old as he was leaving North Hall and turned to walk on Miller Avenue.
READ MORE: Long Island Crime Stories
That is when police say one of the men hit the victim in the head with a black handgun and took a Rolex watch, a cellphone and a gold chain. Police say the men took off in an older-model grey Ford Mustang.
The victim suffered a bruise on his face.
Police are investigating if the thieves are NCC students. They say it appears the victim and the two men knew each other. The victim told authorities that he had said "hello" to them, and even called one of them by his street name, "Trigger."
Joe Muscarella, who oversees the Public Safety Department at Nassau, called the robbery an isolated incident. He says crimes in the area are infrequent.
Anyone with information is asked to call Crime Stoppers at 1-800-244-TIPS.

11 Claims, 7 Drawing Figures IZ J L 7O U 74 75 [,l/i/ 76 APPARATUS FOR CONTROLLING THE TEMPERATURE OF AN INDUCTIV ELY HEATED DRAW ROLL This invention relates to an apparatus for controlling the temperature of an inductively heated thread transporting roll, particularly, in a machine for processing endless synthetic threads.
Heretofore, it has been known to heat endless synthetic threads to a desired temperature by means of inductively heated draw rolls and to control the temperature of the cylindrical draw roll wall supportingthe thread. For example, it has been known to control the temperature by mounting a temperature gauge on a stationary part of the draw roll apparatus and generating a measured value signal corresponding to the effective temperature measured by the gauge for transmission to a control device. This, however, has a number of considerable disadvantages. First, in order to transmit a measured value signal from each gauge of a number of such gauges to a control device provided at a center location, a double lead which in many cases has been relatively long, must be installed. This arrangement is very expensive due to the large number of rolls and measuring points provided on a machine for processing endless threads. Furthermore, sources of errors are created due to the multitude of connections of these leads. Also, the contacts of the leads can be faulty and this can cause biased measured values.
A further disadvantage is that the temperature gauge cannot be placed at the very location at which the temperature is to be measured, i.e. not at the roll wall-surface contacting the thread. Instead, the gauge can only be placed either at the inside surface of the cylindrical roll wall or at a face wall of the roll. The transmission of the temperature, thus, must be effected over a distance, however, short, via the air present in the gap.
It has also been known to have the temperature gauge rotate with the roll. In these cases, the temperature gauge has been provided with an oscillator which transforms the measured value into a frequencyllowever, in this arrangement, the supply of energy to the oscillator presents difficulties. Furthermore, the ap plicability of these rotating elements is limited as to the ranges of rotational speeds and of the ambient temperatures. Also, separation of the measuring signals emitted proves difficult if the heated rolls are located in close vicinity of each other as, e.g. in the drawing arrangements for drawing endless filaments.
Another type of contact-free measuring signal transmission has been known which relies on a rotating Wien bridge. In this case, the constant elements of the Wien bridge have been cast into a disc of synthetic material and the disc has been mounted on the draw roll. The temperature sensitive resistors, that are part of the bridge, are located in the draw roll wall. In addition, transmission coils have been provided in the disc of synthetic material and have been arranged on its circumference. In order to transmit the measuring signal, two transmitter heads partly surrounding the rim of the disc have been needed along with a shielded double lead from each head to the centrally located registering or control device. However, in addition to this complicated cable arrangement, considerable operational deficiencies have been noted, as the heads can be damaged or torn off in case of yarn path disturbances, particularly in case of lap formation. Also, for operational purposes the discs of synthetic material have been found to be disadvantageous, as either the discs or the heads must be taken off before the draw roll can be exchanged. A further operational disadvantage of the Wien bridge resides in that the signal transmitter head can be located in the neutral zone between two transmission coils in case the drawroll is at a standstill. As a result, the signal transmission is interrupted. The draw roll temperature signal, thus, no longer is transmitted and no longer is controlled. This disadvantage can be avoided if two discs with one transmitter head each are provided. This arrangement, however, again is more complicated and expensive.
' A further contact-free measuring signal transmission is known in which a measuring gauge mounted in the cylindrical draw roll wall, i.e. a gauge rotating with the draw roll, has been coupled like a transformer to a signal transformer circuit. The output of this has been a voltage proportional to the temperature measured which has been transmitted to a measuring instrument for direct display or transmitted to a control device as efiective value. The control device, via thyristors, has influenced the heating energy in order to maintain a constant temperature in the cylindrical wall of the drawroll. This method is disadvantageous, as, in addition to a transmission of heating energy, a separate inductive measuring signal transmitter for the signal generated by the temperature gauge as well as expensive signal transmission cables with their disadvantages mentioned above are needed. Also, the necessity of installing this additional inductive transmitter requires very precise installation tolerances. Still further, the draw roll can be taken off by trained qualified specialists only, as the connection between the transmitter and the gauge in the draw roll must be interrupted. A further disadvantage is the danger of contamination of the signal transmitter, particularly if the air contains dust, so that the signal transmitters need periodic cleaning. A still further considerable disadvantage of this measuring method resides in the fact that, due to the signal level transmitted, short cable lengths only to the signal processing device can be used. As a result, a large number of such devices must be arranged along the machine and cannot be arranged in a control cabinet.
Accordingly, it is an object of the present invention to eliminate the disadvantages mentioned above and to maintain the temperature of the cylindrical roll wall within the smallest range of deviations tolerable.
It is another object of the invention to obtain the closest possible coincidence of the location of the temperature measurement and of the location of heat generation and transfer.
It is another object of the invention to obtain optimum dynamic control characteristics.
it is another object of the invention to provide a simplified construction of the roll and of the measuring signal transmission for an inductively heated draw roll assembly.
it is another object of the invention to provide a robust system which is not easily affected by disturbances, which is not subject to wear, and which is independent of the rotational speed and of the sense of rotation of a draw roll.
It is another object of the invention to provide a draw roll which is independent of ambient atmospheric conditions and does not present more difficulties in mounting and taking off than a plain roll without a rotating temperature gauge.
It is another object of the invention to exclude detrimental influences on the measuring signal transmission caused by high working temperatures.
It is another object of the invention to centrally adjust a pre-set value for a large number of control systems simply and precisely.
Briefly, the invention provides a control device for the temperature of an inductively heated thread transporting roll for endless filaments having a stationary iron core arranged coaxially with the-axis of rotation within the cylindrical roll wall and an induction coil surrounding the core which is fed by a source of alternating current for generating an alternating magnetic flux in the rotating cylindrical roll wall supporting the thread. In addition, the control device is provided with a signalprocessing device for influencing a valve for controlling the heating energy to be supplied to the induction coil. This processing device is provided with a connection for a signal proportional to the voltage applied to the coil and with a connection for a signal proportional to the current in the coil as well as with means for transforming these signals into a signal proportional to the resistance of the roll. The processing device transmits this latter signal to a control device for activating the valve.
In one embodiment, the means for forming the signal proportional to the resistance of the roll forms a quotient of the signal proportional to the voltage applied to the coil and the signal proportional to the current in the coil. In another embodiment, the means forms a difference of the signal proportional to the voltage applied to the coil and the signal proportional to the current in the coil.
In still another embodiment, the means for forming the signal proportional to the resistance of the roll can be a bridge circuit. The signal can be generated during the heating period with the network frequency or with a voltage, the frequency of which differs from the network frequency. Also, the signals can be generated between two heating periods by means of a measuring voltage of any desired frequency. In order to influence the valve and the heating energy, an impulse ratio control system or an amplitude control system can also be provided.
These and other objects and advantages of the invention will become more apparent from the following detailed description and appended claims taken in conjunction with the accompanying drawings in which:

Referring to FIG. 1, a thread transporting roll I mounted on a shaft 3 rotatably supported in a housing 2 surrounds a coaxially arranged tube 4 rigidly secured to the housing 2. The tube 4 supports a core 5 made of iron, sheet metal elements radially lined up together or of cast iron, in which core 5 an induction coil 6 is arranged for generating a magnetic flux which originates from the core 5 and closes via the cylindrical roll wall 7. The cylindrical roll wall 7 is also provided with a ring 8 made from an electrically highly conductive material such as copper, brass or aluminum. The magnetic force lines generated by the coil 6, acting as a primary winding, generate an electrical current in the cylindrical roll wall 7 including the ring 8, acting as a secondary winding. This induced current heats up the cylindrical roll wall in order to maintain a desired temperature T of the roll wall 7 which, in turn, heats the endless filaments or threads 9 placed thereon.
In order to heat the synthetic endless filaments under conditions as constant as possible, the pre-set temperature Tmust be maintained; the smallest possible deviations only being tolerable. The corresponding control system thus needs a measured value of the effective temperature as precise as possible. This value is measured and processed using the electrical arrangement described in more detail in the following and illustrated by the schematic diagrams shown in FIGS. 2 and 3.
Referring to FIG. 2, a source 10 of alternating voltage supplies heating energy to an impedance 11 composed of the inductivities and of the Ohmic resistance of the roll according to the equivalent circuit diagram shown in FIG. 3. In this diagram, R is Ohmic resistance of the induction coil 6 forming the primary winding of the transformer formed by the roll; 6 1 denotes the primary leakage inductance; L,, the main inductance; R the equivalent Ohmic resistance for the losses of the main inductance; L62 the secondary leakage inductance; R the Ohmic resistance of the heating ring 8 and of the portion of the cylindrical roll wall 7 influenced by the magnetic flux; and W W the transformation ratio corresponding to the quotient of the numbers W of the primary windings and W of the secondary windings. The cylindrical roll wall 7 as a secondary coil forms one winding only. In this case, the number W is 1 and, thus, W W, equals W The heating energy is supplied to the impedance 11 via a valve 12 which is connected with a signal processing device 13 to which a pre-set value S corresponding to the desired roll wall temperature, i.e. the pre-set temperature T is fed. In addition, as effective value, the signals U, and U representing the effective temperature are fed in the processing device I3. These signals U,, U are obtained by taking off a voltage U proportional to the heating voltage at a voltage divider M and a voltage U, proportional to the current in the coil at a shunt IS. The shunt 15 may be replaced by equivalent means, e.g. by a current transformer. These voltage take-off points are connected with the signal processing device 13 in which the two voltages are transformed into a measuring voltage signal U,, which is proportional to the sum of the resistance according to the equivalent circuit diagram shown in MG. 3. This measuring signal U is processed further in a control device 16, which can be considered as a part of the signal processing device 13, together with a centrally adjustable prest value S.
The circuit arrangement functions as follows: If the temperature of the cylindrical roll wall 7 increases, the impedance 11 increases accordingly. As the roll wall 7 is made from steel and the ring 8 from an electrically highly conductive material, the resistances of these materials depend on their temperature. Thus, the voltages U,, and/or U, change so that the measuring value U of the effective temperature changes by a certain amount in one direction. This, in turn, causes the control device to influence the valve 12 in the sense of a reduction of the heating energy supplied to the impedance ll, i.e. to the roll. If the temperature decreases, the control process functions in the inverse sense.
The advantages achieved using this control system are: I
a. The elements used for transmitting the heating energy, i.e. the primary and secondary winding of the roll are also used for transmitting the measured signal.
b. The use of the cylindrical roll wall including the heating ring as a resistance temperature gauge, i.e. the use of the temperature-dependency of the Ohmic resistance of the cylindrical roll wall itself for measuring its temperature.
c. The locations of energy supply and of the temperature measurement, i.e. the cylindrical roll wall, are not merely located in close vicinity but are absolutely identical. This ensures optimum control characteristics; the static as well as the dynamic deviations being minimal.
d. Robust roll construction combined utmost simplicity and, thus, an inexpensive arrangement.
e. Good long term stability of the temperature measurement.
f. Very simple electrical installation as only the energy supply wires needed in any event need be connected to the roll.
Referring to FIG. 3, the resistance R, of the primary winding which is arranged in series with the resistance R of the secondary winding, also changes with a change of its temperature so that the system according to the ratio of R, and W, x R, measures a mixed temperature value between the temperatures of the windings of the coil 6 and of the cylindrical roll wall 7. Due to this, while the roll 1 is heated up from a cold state, an excessive roll wall temperature is initially prevented. deviation disappears, however, as the temperature of the winding nears the roll temperature, the influence of the value W, x R being considerably more important than the comparatively small value of the resistance R,. In draw rolls of the usual type, the value W, x R is about 90 percent of the total impedance lll.
Referring to FIGS. 4 and 5, the processing of the voltages U, and U,, can be effected in different manners. Referring to FIG. 4, the divider circuit arrangement contains, in analogy to FIG. 2, an induction heating arrangement of a roll indicated by an impedance 117, a shunt 18 arranged in series, a voltage divider l9 and a valve 2%)). A suitable signal processing device 21 for influencing the valve 24D includes a division device 22 connected to the voltage divider 19 so as to receive the voltage U,, and to a point between the shunt 18 and impedance 17 to receive the voltage U,. In addition, the processing device 21 has a difference amplifier 23 and trigger 25 in series connected directly and via a delay 26 to a flip-flop 27. This is followed by a control signal generator 28 for the valve 20. Between the division device 22 and the difference amplifier 23, a lead 24 is arranged for supplying the pre-set value of the temperature represented by a voltage.
This arrangement functions as follows:
The heating energy flows via the valve 20 to the inductively heated roll which is indicated by the impedance 117. The signals U, and U,, taken off are transmitted to the division device 22 in which the quotient of the voltage and current signals U,,/ U, are formed as an output which is directly proportional to the impedance 17 of the roll 1 and, thus, to the effective temperature of the cylindrical roll wall7 If the temperature exceeds the pre-set value delivered via the lead 24, the current signal U, at the input of the division device 22 diminishes due to the increased resistance of the impedance l7 and, thus, the output signal of the division device 22 increases. In this way, a positive output voltage is generated at the amplifier 23 which reaches the flip-flop 27 via the trigger 25 and resets it. This causes a shutting signal to be given to the valve 2d by the control signal generator 28. Heating of the roll 1., thus, is interrupted. Simultaneously, an impulse is given to the delay 26, which, in turn, limits an impulse after a time delay 26 which can be chosen as desired e.g. 2 seconds). This latter delayed impulse brings the flip-flop 27 back into working position, so that the control sigial generator 28 emits an opening signal to the valve 20. If, e.g. the cylindrical roll wall 7 has not yet cooled down sufficiently, i.e. down to the desired temperature T, the heating is immediately interrupted again. In order to form the quotient V,/ U, conveniently, the mean values U,, and U, are formed first and then are subsequently divided. This, however, causes unprecisions, as the inductive current portions are incorporated in the mean value of U. If more precise values are to be obtained,
can be formed if needed, where it indicates the duration of the period, and
(1 f UxUdt The value R U /P is obtained by dividing these two values.
The advantage of using the division principle is that a resistance measurement, i.e. the output signal of the division device, is directly proportional to the effective temperature of the cylindrical roll wall 7 over a large range.
Referring to FIG. 5, in addition to a volage source 29 with a network frequency f, the valve 30 and the impedance 31 of the roll, a switch 32 is arranged in the heating current circuit. This switch 32 is switched to the position indicated with dashed lines at certain time intervals by a stroke device 33. A voltage source 34 of any voltage desired and of the frequency f is connected via the switch 32 in its switched position to the impedance 31 during the time period during which the stroke device 33 opens the heating current circuit. The voltage source 34 is also connected via leads 35 and 36 with a phase discriminator 37. Furthermore, a bridge arrangement 38 with a bridge branch 39 with phase compensation and a bridge branch 40 with pre-set value adjustment is provided. The condensors provided in the bridge branch 39 are used for compensating the inductivities comprised in the impedance 31. The bridge diagonal is connected with a. difference amplifier 41, the output voltage of which is proportional to the bridge diagonal voltage. A lead 42 from the difference amplifier connects to the phase discriminator 37 and an amplitude discriminator 43. The outputs of the phase discriminator 37 and of the amplitude discriminator 43 are connected with the input of the control signal generator 44 which generates the adjusting value for the valve 30 for the next heating period. In order to obtain ideal control characteristics, the control signal generator 44 can be constructed as a PID control device. Deviation measuring and display devices 45 are also connected to the phase discriminator 37 and to the amplitude discriminator 43 as shown.
The control device with the bridge arrangement described above functions as follows:
If the switch 32 is in the position shown, the roll represented by the impedance 31 is heated. Should the stroke device 33 switch the switch 32 into the position indicated with dashed lines, the measuring period is started followed by a heating period if the switch 32 is switched back. During this measuring period, the stroke device 33 influences the control signal generator 44 in the sense that the adjusting value for the valve 30 for the following heating period is generated. With the switch 32 in the position indicated with dashed lines, the impedance 31 is connected to the bridge arrangement 38 as a branch. The impedance 31 is then compared herein with the pre-set value in the branch 40. A voltage corresponding to the deviation of the resistance in phase and amplitude is then generated in the diagonal of the bridge 38 and is transmitted to the input of difference amplifier 41. The output voltage of the difference amplifier 41 proportional to the bridge diagonal voltage is transmitted to the two discriminators 37 and 43.
The phase discriminator 37 compares the phase of the output signal of the difference amplifier 41 with the phase of the voltage source 34. As the phase of the bridge voltage changes by 180 degrees while the balancing point of the bridge 38 is passed, the phase clearly indicates whether the impedance 31 is below or above the pre-set value, i.e. whether the roll temperature is above or below desired temperature T. On the other hand, the output signal of the amplitude discriminator 43 represents the size of the deviation from the pre-set value. The output signals of the two discriminators 37, 43 are transmitted to the control signal generator 44 in which the adjusting value for the valve 30 for the next heating period is now formed. This can be effected in one of two known manners. That is, the phase control angle in the valve 30 can be adapted or the duration of the heating period can be adapted by controlling the impulse width.
The output signals of the two discriminators 37, 43 also are transmitted to the deviation measuring and display device 45 for supervising and displaying the roll temperature.
The elements 34, 39 and 40 can be used in a plurality of control circuits and the adjustment of the pre-set value can be effected e.g. for a whole machine at the bridge branch 40. Also, the network for the heating circuit can be used as the voltage source 34. Furthermore, eliminationof the switch 32 can be envisaged provided the frequency f of the voltage source 34 differs sufficiently from the network frequency f. In this case, the stroke device 33 can be eliminated.
A further simplification is possible if the voltage source 29 and the voltage source 34 are united, provided that the voltage drop via the valve 30 is neglegible, so that the switch 32 can also be eliminated.
The bridge circuit arrangement presents the advantages of the division device arrangement as well as a less complicated circuit design. The use of a measuring frequency independent of the network frequency reduces the susceptibility to network noise and permits more precise sine shapes of the signals to be fed to the amplifier, and thus increased measuring precision.
Referring to FIG. 6, an example of a simplified arrangement, a half-bridge 46 can be arranged in front of a valve 47. The supply to the half-bridge 46 is effected from a heating voltage source 48. The valve 47, in this case, must be designed such that the changes in the voltage drop via the valve 47 are neglegibly small. This can be the case, e.g. with a thyristor. One of the bridge resistors is replaced by a current transformer 49 which terminates in a resistor (not shown). After the difference amplifier 50 corresponding to the amplifier 41 above, the other elements as described above with reference to FIG. 5 follow.
Referring to FIG. 7, the control circuit includes an inductively heated roll represented by an impedance 51, an adjustable voltage divider 52 and a valve 53. A suitable signal processing device 54 is constructed as follows.
A voltage source 52 is connected via a converter 55 and a mean value forming device 56 with a difference amplifier 57. The difference amplifier 57 is also connected to' a shunt 58 via an analog converter and a mean value forming device 59. After the difference amplifier 57, a trigger 60 follows which is connected directly and via a delay 61 with a flip-flop 62. The flipflop 62 is thereafter connected to a signal generator 63 for the valve 53. A lead 64 carrying the voltage of the pre-set value, provided for a plurality of identical systems, is connected to the amplifier 57 input for U,
The arrangement functions as follows:
The heating energy flows via the valve 53 to the inductively heated roll represented by the impedance 51. The previously converted voltages U and U are averaged over a certain time constant via the mean value forming device 56 and 59 and are then transmitted to the difference amplifier 57. The voltage signal U by means of the adjustable voltage divider, is now chosen such that at the desired roll temperature T, the current and voltage signals transmitted to the difference amplifier 57 are equal. If the pre-set temperature is now exceeded, the current signal U, at the input of the amplifier 57 becomes smaller than the voltage signal U due to the increased resistance of the impedance 51. Thus, a negative output voltage is generated by the amplifier 57 which is further processed as in the example described with reference to FIG. 4.
The circuit design arrangement with difierence formation is characterized by uncomplicated circuits and is particularly suited for applications with a small range of adaption of the pre-set temperature.
The heating control arrangements described with reference to FIGS. 4 and 7, thus function as a special type of a two-point control system in which the supply of heating energy is interrupted each time the preset temperature value is reached. The near-ideal arrangement with respect to control dynamics of heat generator, measuring gauge and heat consumer makes this arrangement feasible without noticeable overshooting and pendling. The valve and the control signal generator, however, can also be designed such that the amplitude of the heating voltage is adjusted continuously (e.g. phase control angle, adjustable transformer) and that the control characteristics are of the PID type.

"Pretty, yet simple to make how I would describe this bracelet. Any girl would like to make this and wear one. This would be a great group project for girls to make together at a sleep over or a birthday party. I think I'll have to make one for me too."
"Get a life.Quit your bickering."
"Speaking of gadgets...More than anything I would like to find a clicker or counter that I could click with my foot. When I am working with my hands and doing multiple pieces, it would help if I didn't have to stop at every one to count it on a hand clicker. And the finger one just gets in my way. Any help?"

Floating around in the How Do I Price My Work universe is the formula of multiplying; doubling (2x), tripling (3x), or quadrupling (4x) your Cost Of Goods (materials and supplies used to make your item). I think this formula has been around since the first crafter sold an item to her sister, neighbor, or friend. It's very basic and easy for those of us who are creative, but not so interested in complicated mathematical formulas. However, I think even if you use this type of pricing formula you need to make sure you are getting paid for your labor.
To find out more about this formula, head over to Creative Income Blog!
