Title: Electrically conductive rubber
IPC: C08K3/04
Filed: 1945-11-08
Abstract: An electrically conductive rubber composition capable of being shaped and vulcanized is prepared by mixing a rubber gum stock such as natural rubber, polymerized chloroprene, polyisoprene, or copolymers of butadiene 1.3 with acrylonitrile, styrene or isobutylene, with vulcanizing agents, adding thereto a rubber solvent, such as gasoline, benzene, toluene or ethyl methyl ketone, sufficient to yield a solid mixture containing 20 to 55 per cent of solvent, and mixing therewith conductive carbon black and more of the same solvent to obtain a mixture containing 20 to 55 per cent of solvent and from 5 to 35 per cent of carbon black. The carbon black and the additional solvent may be added together either intermittently or continuously or they may be added alternately.  The compositions may include pigments, antioxidants, vulcanizing agents and accelerators, and may be used as impregnants for woven fabrics, spread into thin sheets, or thinned by the addition of more solvent to form thin cements capable of application by dipping, brushing or spraying, these products being dried after fabrication and vulcanized by heating.

Title: Electrically-operated race game apparatus
IPC: A63F9/14
Filed: 1936-10-19
Abstract: 466,748. Race - game apparatus. LENNARD, E. S. Oct. 19, 1936, No. 29925 /35. [Class 132 (ii)] In race-game apparatus wherein a plurality of electrically driven model horses or other representations are moved under competitive or chance control over parallel or endless tracks, each horse is loosely mounted on its carriage so that if it becomes detached therefrom, for example, while being manoeuvred over a hurdle &c. the circuit of the driving means therefor is de-energized. Each horse 1 is pivoted to a pin 11 resting in a sleeve 10 secured by an insulator 8 to an oval sectioned sleeve 6 slidable on an oval bar 5 rigid with a carriage 3 driven over a fixed track. A rod 13 is pivoted at its forward end, and, when rollers 24 thereon encounter ramps 25 by the sides of the track the rod is rocked as shown in Fig. 3, so that spring arms 14 rigid therewith elevate the sleeve 6 through projections 15 thereon, and a metal wire 17, connected to one of the arms 14 and ending in a loop 18 through which a wire 20 rigid with pin 19 is threaded, tilts the horse as it is raised to pass over a hurdle H. Each player controls the speed of his horse through a rheostat, and, if the hurdle is taken too rapidly, the horse becomes detached from the sleeve 10. This breaks the circuit to the driving motor through leads 21, 22 and stops the carriage 3. Chance control may be provided by introducing resistances in the various motor circuits. fortuitously, and jockeys 2 may be loosely pinned to the horses 1 so that they are unseated when hurdles are taken badly but not sufficiently so to displace the horse from its support.

Title: Arrangements for changing over to spare amplifiers or oscillators
IPC: H03F1/54
Filed: 1939-11-14
Abstract: 536,454. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., JACOBSEN, B. B., and MARTIN, R. A. Nov. 14, 1939, No. 30038. [Class 40 (v)] [Also in Group XXXIX] In a system involving a number of valve amplifiers, only one of which is in use at a time, the output of the amplifier in use is employed to block the remaining amplifiers. In Figs. 1 and 2 amplifiers A, B are fed from input IP through transformers ITA, ITB and comprise valves VA1, VA2 and VB1, VB2 having output transformers OTA, OTB, supplying a common output OP. If for example amplifier A is in use, current from a transformer PTA is rectified at a bridge W1 ... W4, and the voltage developed across R5 is applied through the secondary of ITB to bias amplifier B to cut-off. If amplifier A fails, B is unblocked, and in similar fashion develops a voltage to block A. For. a short interval both amplifiers are operative and, due to the use of slowrelease relays a lamp LA is lit and a non-urgent alarm is given by relay NUA. This alarm cannot be released until test link PA1, PA2, PA3 is moved to position SA1, SA2, and the amplifier tested and repaired. If the link is inadvertently removed during the operation of the amplifier the relay NUA is operated. If however both amplifiers fail or if the input fails, relay M operates to light lamp LS3 and urgent alarm is given by relay UA. A hand key is also provided for a manual change over. For the above system to operate when the input consists of speech currents, a pilot frequency is added to give the necessary bias voltages. One of the amplifiers can be selected for operation by means of pilot currents having frequencies corresponding to the individual amplifiers. The output is bridged by rectifiers and band pass filters so that when a selected amplifier is energized by its pilot frequency, the remaining amplifiers are biassed to cut-off. If desired, the filament currents of the standby amplifiers are also interrupted by means of pilot currents. The amplifiers may be connected to output by means of differential transformers to avoid power being absorbed by the non-operative amplifiers. Reference has been directed by the Comptroller to Specification 637,507, [Group XL (c)].

Abstract: 484,580. Brakes ; automatically-adjustable couplings. LUCAS, Ltd., J., and WATSON, E. A. Nov. 6, 1936, No. 30248. [Class 103 (i)] [Also in Group XXIV] To minimize chattering at low speed, due to backlash in the gearing or clutch through which the ignition magneto is driven from an internal-combustion engine, a brake is applied to a part on the driven side of the gearing and is released by centrifugal means at higher speeds. The shaft a driven from the engine by gearing or a clutch drives the magneto spindle b by known means including centrifugal masses c pivoted at h on a disc d secured to shaft a and connected by links e to an arm f secured to the spindle b. The masses c are controlled by springs g and are adapted to vary the ignition timing in accordance with the speed of the engine. The brake device comprises levers i formed each with a brake shoe j and pivoted on the pins h which carry the masses c. At low speeds the shoes j are applied to a stationary ring l by springs k connected to the levers and to the disc d but when a predetermined speed is exceeded, centrifugal force acting on the levers withdraws the shoes from the ring l.

Title: Circuit arrangement for the blanking of the horizontal flyback in television receivers
IPC: H04N3/24
Filed: 1957-09-27
Abstract: 812,865. Cathode-ray oscilloscopes. STANDARD TELEPHONES & CABLES Ltd. Sept. 27, 1957 [Sept. 29, 1956], No. 30329/57. Drawings to Specification. Class 40.(7). [Also in Group XL (b)] The horizontal flyback trace in a television receiver is blanked by means of a negative pulse obtained from the line output transformer and applied to the cathode-ray tube by way of the suppressor grid of the pentode forming the video output stage. The pulse is followed by a transient oscillatory component, but the suppressor characteristic, which is flattened in the region of low voltages, attenuates the transient and prevents any disturbance of picture brightness. The invention is stated to be of particular application in receivers employing differential equalizers to correct for attenuation of the higher video frequencies.

Title: Improvements in or relating to voltage regulators
IPC: H02P9/18
Filed: 1946-10-14
Abstract: 625,136. Automatic control systems for generators. McMILLAN, A., and MITCHELL, J. T. D. Oct. 14, 1946, No. 30547. [Class 38 (iv)] [Also in Group XXXVII] In a voltage regulator, the operating coil controls an armature which progressively effects the insertion of series resistors in the field circuit of a generator. As shown, Fig. 1, the control coil L1 positions an armature which causes contact members to engage the fixed contacts C1 ... C6 which short the resistors R1 ... R6 in series with the shunt field of generator G1. At low generator voltages the field of the second regulator coil L2, which is employed to reduce to percentage voltage variation permissible, opposes L1, but as the voltage rises the energization of L2 falls until, finally, contact C7 is made and the current through L2 is reversed so that L1 and L2 are now mutually assisting and the tendency of C7 to vibrate is reduced. The movement of the regulator armature is made proportional to the voltage across coil L1 by means of springs, and the profiling of the member engaging the contact members is such as to cause each contact to be made at the correct voltage level. In a further modification, not shown, the coil L2 is removed and two neon tubes are placed in series with coil L1.
