Title: Improvements in the manufacture of high ohmic resistance conductors
Inventor: BUCHANAN ROSS W
IPC: H01B1/24
Filed: 1952-01-25
Abstract: 702,429. Ohmic resistors. GENERAL MOTORS CORPORATION. Jan. 25, 1952, No. 2055/52. Class 37 A conductor cable of high specific resistance particularly suitable for use as an H.T. ignition/radio interference suppressor cable is in the form of a cord of nylon or glass or other fibres impregnated with particles of carbon or metals, such as aluminium, copper or iron, or metal oxides, sulphides, carbides, nitrides or borides. In the manufacture of the cable an essential step consists in treatment with a wetting agent to' improve. the capillarity of the fibres. Fig. 2 shows a nylon 4-core braided cord and Fig. 1 a continuous roller process for impregnating such a cord with graphite. In Fig. 1 the cord passes continuously from a spool 2 into a de-sizing and de-greasing chloroform bath 4 and thence through a drying oven 8 into a tank 12 where it is submerged in an aqueous solution of wetting agent. The cord then passes through a drying oven 14 and into a colloidal graphite impregnating tank 18 which also contains a small proportion of wetting agent. A compression die 20 squeezes the cord as it emerges from the tank 18 and passes into the impregnant drying oven 22 ; the final stages consist in immersion in boiling water in tank 26, for removal of surface or excess wetting agent, drying in an oven 28 and winding on a spool 30. If one dip in the impregnating solution is not sufficient to produce the desired thickness of graphite coating the equipment items 18, 20, 22 are repeated. In the treated cord each single fibre 40, Fig. 6, comprises an inner coating of wetting agent and an outer uniform coating of graphite 42. The cable in service form has an outer covering of rubber, Figs. 4-5 (not shown). The Specification includes references to preferred graphite impregnating and wetting agent solutions and concentrations and gives full instructions covering dipping and drying periods and oven temperatures.

Abstract: 507,512. Dynamo - electric machines. TUSTIN, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Jan. 21, 1938, No. 2122. [Class 35] In a commutator dynamo-electric machine provided with interpoles 1, conductive damper bars 4, 5 are so disposed in relation to conductors completing commutation and particularly the last such conductor in a slot that they intersect a large amount of those inter-tooth fluxes which extend outwardly beyond the armature periphery and so exert a damping effect on such changes of flux, the bars extending axially of the machine on either side of the interpoles so that for either direction of rotation there are effective damper bars. The interpole is stepped at 7 and stepped or chamfered at 8 to hold the damper bars and to provide the desired form of interpole field. The bars are secured to the interpole by rivets 6 which are of low conductivity metal such as iron to avoid the formation of a circuit encircling the pole.

Filed: 1946-01-29
Abstract: 629,160. Control systems for consuming devices. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Jan. 29, 1946, No. 2876. [Class 38 (iv)] [Also in Group XXXVII] In an electronic device for controlling the magnitude and phase of a square wave alternating potential in accordance with the magnitude and sense of a unidirectional potential, a reference square wave alternating potential is applied to the grid of an electronic tube V2, the anode of which is connected to a tap on an impedance 3 in the anode circuit of an electronic tube V1 having a common cathode resistance with V2. The unidirectional control potential is applied to the grid of VI. The amplitude of the reference potential is sufficient to drive V2 from the grid current point to cut off on alternate half-cycles, and the bias developed across the common cathode resistance cuts off V1 while V2 is conducting, and allows V1 to conduct while V2 is cut off. The voltage drop across the impedance is applied to a utilization circuit, which may be a motor control device, and the tap is adjusted so that, when the control potential is zero or a predetermined datum value, the voltage drop across the impedance when V1 conducts equals the voltage drop across the tapped-off portion when V2 conducts, and the potential applied to the utilisation circuit is consequently zero. Deviation of the control potential from zero or datum varies the conducting current of V1 so that a square wave alternating potential appears across the utilisation circuit dependent in magnitude and phase on the magnitude and sense of the control potential. The reference alternating potential may vary sinusoidally.
