Abstract: 397,101. Supply systems for highfrequency apparatus. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts- Ges.; 2, Friedrich Karl-Ufer, Berlin.) Nov. 12, 1931, No. 31379. Convention date, Nov. 12, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (iv).] A coil 1 surrounding a crucible 2 is directly included in a circuit which generates highfrequency current by the use of thermionic valves. In Fig. 1, current may pass from connection 3 to either end of the coil 1 according to which of the valves is rendered conducting by grid fluctuations in voltage caused by a transformer 11, 12, the primary 12 of which is supplied with alternating current of a definite periodicity. In Fig. 2, condenser 5 is charged when valve 6 passes current, and discharged when valve 7 passes current, thus setting up oscillations in coil 1. Condenser 5 may be adjusted to form with coil 1 a circuit resonant to the frequency of the oscillations or the oscillations may be adjusted in frequency to produce the same result.

Abstract: 1,148,588. Electric meters. HONEYWELL Inc. July 13, 1966 [July 26, 1965], No.31562/66. Heading G1Q. The movement of a moving coil meter consists of two coils, a driving coil 12 and a pick-up coil 28. The latter picks up a voltage proportional to rate of deflection by electromagnetic induction and also a signal proportional to deflection from a potentiometer 34. The driving coil is connected to the output of an amplifer whose input is the difference between the signal voltage and the voltage picked up by coil 28. The arrangement thus provides displacement and velocity feedback damping. As shown, the two coils are wound on a common former 14 carried by an armature 16.

Title: Machine for applying rotatable closure caps to containers
Inventor: MCELROY ROBERT KENNETH
IPC: B67B3/20
Filed: 1957-10-11
Abstract: 818,049. Closuring containers. WHITE CAP CO. Oct. 11, 1957, No. 31879/57. Class 125(2). Relates to apparatus for supplying screw or bayonet caps 52 to containers in which the latter are carried by conveyer 13 and front and rear container-gripping belts 113 moving at the same speed as the conveyer under a cap shoot 6 to extract the caps and then under cap turning means. According to the invention. the turning means comprises endless front and rear belts 145, 146 bearing on opposite top edge parts of the cap and driven at such speed that the operative run of belt 146 is driven faster than the conveyer 13 and belts 113 by as much as the operative run of belt 145 is driven slower than these parts. As shown, filled containers pass centering members 25 on the conveyer and then engage the leading edge of the lowest cap in short 6 and draw it along between a guide wheel 51 and rails 47. The top of the cap is then engaged in succession by two spring-pressed levelling plates 65, 66 and as it passes under the latter the side of the cap rubs against a pressure pad 84 which tends to turn it so that the cap threads fall into the container threads. The cap-turning means is mounted in a casing 10 which contains a compound pulley 147 having four pulleys 148, 150, 151, 152, the two latter being of the same intermediate diameter and driving the container-gripping belts 113 at the same speed as conveyer 13. Pulleys 148, 150 are respectively smaller and larger than the other pulleys and drive belts 145, 146 at the required speeds. The operative runs of these belts pass over guide rollers 144 so shaped and mounted as to cause the belts to bear downwards and inwards on top edge parts of the caps. Rollers 144 are mounted on a frame 140 urged downwardly by adjustable resilient means to apply top pressure to the caps. Means are provided for adjusting the tension of belts 145, 146. Belts 113 also pass over pulleys 200 and are tensioned by springs 204. They are urged into engagement with the sides of the containers by spring-urged lateral rollers. The cap short 6 and the casing 10 carrying the various belts are vertically adjustable to suit different container heights and the distance between belts 113 can be varied. The closuring is effected in a steam apmosphere and steam is directed from apertured pipe 37 on to caps in the short 6. A modified form of machine for applying caps of large diameter is described. Specifications 383,744, 432,463 and 547,228 are referred to.

Title: Process for the production of polyphenylene oxides
Inventor: ISMAIL MOHAMED ROSHDY
IPC: C08G65/44
Filed: 1966-07-15
Abstract: Polyphenylene oxides are obtained by oxidizing with gaseous oxygen a solution of a disubstituted phenol in the presence of an alkali-metal phenolate and a complex of a cuprous salt and an amine.  The disubstituted phenols have the formula <FORM:1091806/C3/1> where R and R1 are hydrocarbon radicals (which may be halogenated), hydrocarbonoxy radicals, halogenated aryl radicals or halogenated aryloxy radicals.  The alkali-metal phenolate may be a derivative of the phenol to be oxidized and may be prepared in situ.  From 0.1 to 1.0% by weight of alkali metal phenolate based on the phenol, may be used.  In examples polymers are obtained from 2,6-dimethyl phenol dissolved in chloroform, in a mixture of toluene and isopropanol, and in dichlorethane, in the presence of the sodium salt of 2,6-dimethyl phenol and complexes formed from cuprous chloride and pyridine and cuprous chloride and diethylamine.  Other phenols, cuprous salts and amines are mentioned.

Abstract: <PICT:0801078/III/1> A process for recovering wax from waxed feathers comprises feeding steam into and through the feathers held in a container, running off the molten wax, and thereafter subjecting the feathers with the reduced wax content to a pressing operation while the wax is maintained in a molten state, whereby a substantial proportion of the residual wax is recovered.  A suitable apparatus is illustrated in the Figure.  Container B, provided with trunnions P, is suspended by springs S from running members Q, adapted to run along track O.  To start the cycle of operation, container B is moved to position 1 directly beneath bottomless canister A which is provided with a lid G.  Within the canister is a steam injection unit I.  The canister and container may be clamped together and the unit then charged with waxed feathers. On passing steam through I, the wax melts and passes through perforations M and slits M1, into receptacle C, which is provided with heating coil H, to maintain the wax in a molten condition, and steam exhaust pipe K; the molten wax may be run off through valve J.  After the steaming operation, container B is moved to position 2 and there subjected to pressure by means of plunger D, which is actuated by an hydraulic jack.  The residual wax pressed out of the feathers is collected by funnel F and is removed. Container B is then moved to position 3, titled to facilitate removal of the spent feathers, and then passed back to position 1 for a new cycle of operation.

A device for controlling the flow of gas to a stove or boiler comprises a body 10 in which are disposed main and secondary valves 33, 28 for controlling the flow of gas through respective main and secondary gasways through the body of the valve, a manually operable starting member 18 and electromagnetic holding device 13, the main and secondary valves being so arranged as to be maintained closed with respect to each other when the starting member is operated to open the secondary valve, and to be opened upon release or return of the starting member only if the required predetermined current conditions have been established in the electromagnetic holding device. When the starting member is displaced to the left, the valve 28 is lifted from its seat to permit gas to flow to a pilot burner through passages 21, 22. The pilot burner heats a thermocouple to energize the electromagnetic holding device 13 which holds an armature 36 on the main valve 33 when the starting device is released, a passage 31, 29, 32 for gas flow to a main burner being opened as the valve 28 returns to an intermediate position determined by a spring 19. If the pilot burner should be extinguished and the electromagnetic holding device thus de-energized the valves 33 and 28 are both closed by the spring 37.
