Title: Superconductive device and method for the production thereof
IPC: H01B3/30
Filed: 1966-02-24
Abstract: 1,143,185. Superconductor devices. UNION CARBIDE CORP. 24 Feb., 1966 [25 Feb., 1965], No. 8075/66. Heading H1K. In cryotrons the gate and control members are separated by a layer of a p -xylylene polymer. This polymer may be poly-(p-xylylene) itself or may have as its basic units α- and/or nuclearsubstituted p-xylylene radicals. Production of the polymer layer is as described in Specification 1,143,186. In the specific embodiment a Pb ground plane is covered with a layer of the polymer, a gate conductor is deposited, a patch of polymer is formed from the vapour state (by masked deposition or by overall deposition and selective removal by electron or ion-beam bombardment or by glow discharge), and a control conductor then deposited. The Specification suggests the use of a Pb control conductor with a tin or tantalum gate and also suggests the use of devices in which the state of magnetization of unspecified superconductive ferromagnetic rare-earth metal alloys is altered by the field arising from a control conductor. Glass, ceramic, or plastic substrates may be used and many devices may be formed on one substrate and may be interconnected.

Title: Distinguishing valid from invalid transitions in a two level logic signal
IPC: H04B1/10
Filed: 1976-03-01
Abstract: 1534053 Rejecting spurious pulses UNITED TECHNOLOGIES CORP 1 March 1976 [3 March 1975] 08092/76 Heading H3T Changes lasting more than a preset time from either level of a two level logic signal to the other are detected by sensing the occurrence of a transition in said signal, actuating timing means having a preset timing period upon the occurrence of a transition from a first level to a second level, resetting the timing means if the logic signal returns to the first level before the end of the preset period and producing a first output signal at the end of the period if the timing means is not reset. Once the first output signal has been produced, a transition to the first level reactuates the timing means, which is reset if a transition to the second level occurs before the end of the preset period and a second output signal is produced upon expiration of the period if the timing means is not reset. Two embodiments using TTL circuits are described. In one embodiment, Fig. 3 (not shown) three flipflops are used with a synchronous counter as timing means in a circuit which gives a short pulse out on one of two lines each time the input makes a valid high or low transition. In the other embodiment, Fig. 4 (not shown) a monostable circuit is used as timing means together with two flip-flops in a circuit which gives a continuous high or low signal according as the input is high or low.

Title: Improvements in the manufacture of hydroxyl compounds
IPC: C07C39/215
Filed: 1943-05-21
Abstract: Dienaestrol [g  : d -bis-4-hydroxyphenyl-D b d -hexadiene] is prepared from g -d -bis-4-hydroxyphenyl-g -d -diol after acylation of the phenolic hydroxy groups by means of an aromatic acylating agent by dehydration by treatment with a mixture of an aliphatic acid chloride and aliphatic acid anhydride.  The preferred aromatic acylating agents are benzoyl chloride and toluene-p-sulphonchloride. The preferred dehydration mixture is a mixture of acetyl chloride and acetic anhydride.  In examples: (1) 4-hydroxypropiophenone is reduced by sodium amalgam in aqueous caustic soda solution, and then stirred with benzoyl chloride. The benzoyl derivative so formed is purified and refluxed with a mixture of acetyl chloride and acetic anhydride then saponified with alcoholic potassium hydroxide to form dienaestrol; (2) p-hydroxypropiophenone is reduced as in example (1) and acylated with toluene p-sulphochloride.  The ditoluenesulphonate thus produced is treated with a mixture of acetic anhydride and acetyl chloride, and finally hydrolysed with alcoholic potassium hydroxide.  Specifications 523,515, 566,723 and 566,724 are referred to.

Abstract: 512,730. Electric control systems. MURPHY RADIO, Ltd., BOYD, J. D. A., and FISHER, L. March 16, 1938, No. 8167. [Class 40 (i)] In a selective motor-operated tuning system, the selector member makes more than one revolution for each cycle of adjustment of the tuning member, the brush setting being made unique by giving the selector member and its brushes relative motion in a second direction. Upon a circuit being completed over a contact 8, motor 10 runs to rotate the condenser 2 and the shaft 5 carrying the drum 1 comprising two conducting members separated by a strip of insulation, the shaft moving axially due to the worm 6 and nut 7, until the contact passes on to the insulating strip to open the motor circuit. In a modification, Fig..2, the drum is not axially displaced but is provided with helical grooves 12 with which spring contact members 11, adjustably mounted on a ring 14, engage. It may be arranged that the contacts are mounted on a reciprocating carriage, the drum being rotated without axial movement. In a further modification the contacts may move in spiral paths over a contact disc. The Provisional Specification described a modification wherein the motor circuit is controlled by two contact making switches which rotate at different speeds.

D., 48, Church Road, Stanley, Liverpool. March 19, 1932, No. 8260. [Class 40 (iv).] A gain-regulating arrangement particularly applicable for the operation of direct-current relays by alternating current signals of voice frequency comprises a pair of valves in cascade, the grid bias of the second valve being derived from rectified alternating current in the output circuit of the first valve. The Figure shows an amplifying valve V1 and a rectifying valve V2 the negative bias of both being determined by the voltage across condenser C1 which is derived from the rectified output of the valve V1. In addition the output of the valve V2 may be rectified and applied to positively bias the valve input. The coupling between the amplifier and the rectifier may be a tuned circuit so that the latter is responsive only to a predetermined frequency.

Abstract: 495,168. Coating surfaces. HERRMANN, E. March 18, 1938, No. 8429. Convention date, April 1, 1937. [Class 93] Relates to the production of a felt-like surface on an article such as a shoe-heel, a button, a buckle or a cycle-grip, by applying a layer of adhesive and then projecting short fibres on to the sticky surface by means of a jet sprayer or spraying pistol, and consists in varying the distance of the sprayer from the surface. A high pressure, for instance four atmospheres, is used in the sprayer, which is first situated at 70 ... 80 centimetres from the surface and preferably at an angle of 45 ... 60‹ thereto, and, after a layer has been applied, is brought continuously nearer to the surface until it is about 25 centimetres therefrom, whereby the fibres impinge on the surface with increasing force.

Abstract: 536,718. Cutting or dividing glass. MAXWELL, R. E. May, 14, 1940, No. 8638. [Class 56] A method of removing the necks of ampoules, or of cutting glass tubes, consists in placing an ampoule in an horizontal position, supporting the rear end only while resting the neck portion on a rotating abrasive disc, and rotating the ampoule on its longitudinal axis to cause the disc to form an annular groove in the neck. A device for carrying out the method comprises a thin disc 24, of abrasive material, attached to a shaft 27 which is provided with a flywheel 28 and is rotated by a crank handle 31. A bracket 18, adjustably attached to the casing of the device, has an horizontal top section 19 along which a support 22 is adjustable. In use, an ampoule 21 is placed with its rear end on the support 22 and its neck resting on the disc 24, lateral movement of the neck being prevented by spaced walls 38. While the disc is rotating, the ampoule is pressed downwards lightly, and rotated, by the top of a fingec to form a groove around the neck of the ampoule. The neck can then be broken off by inserting it in one of a number of holes 47 in an inclined section of the bracket 18. A push-button brake 45 is provided to stop the rotation of the disc. In a modification, the disc is rotated by an electric motor.
