Title: An improved electrical interrupter
IPC: H01H71/24
Filed: 1952-03-24
Abstract: 704,927. Electrically-tripped switches; fluidblast circuit-breakers. MITCHELL, F. March 24, 1952 [March 29, 1951], No. 7476/52. Class 38(5) The circuit-breaker comprises a cartridge 39 carried by a pair of insulators 7, 19 which are relatively-movable so as to operate the cartridge which contains contacts arranged in arc-extinguishing means. The insulator 19 is attached to a lever 27 which is pivoted at 11 in a box 10 and is normally held in the position shown by a lever 26 pivoted at 30 and restrained by a catch 25. The cartridge is secured by a lower clamp 40 and an upper clamp 41 which is pivotally carried by the insulator 19 together with an operating pin 38. If an overload or other fault occurrs, the catch 25 is tripped by a plunger 21 acted on by a coil 20, thereby releasing levers 26, 27 and insulator 19 which moves clockwise so that the pin 38 engages a frangible plate 44, Fig. 5, at the top of cartridge 39. This causes the enlarged head of a pin 52 to be lowered from between a split contact 49 which is thus moved downwards by a spring 50 out of engagement with a fixed nozzle contact 48, a liquid blast being forced between the contacts in the process. The cartridge may comprise a solid gasevolving material 58, Fig. 6, with the contacts 60, 61 arranged at the lower end for operation by removal of pin 62 through linkage (not shown) by insulator 19, or directly by a movable insulator 7. An auxiliary current-carrying element 64 is broken, when contact 61 moves upwards, so as to form an arc to initiate the vaporizing of material 58. When the cartridge is replaced, the insulator 19 is returned to its normal position by resetting levers 26, 27 and catch 25 by means of an external lever, Fig. 3 (not shown). The downward movement of insulator 19 is limited by a spring buffer 17, 18. The line terminals 36 may be earthed after operation by earthing blades, Fig. 2 (not shown). Several phases may be linked for simultaneous operation by means of the spindle 11 and the catch 25 may be tripped manually.

Abstract: 982,274. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 26, 1963 [March 8, 1962], No. 7710/63. Heading H1K. A monolithic semi-conductor device comprises a semi-conductor body having regions of different conductivity types arranged to define a four-region, three PN junction negative impedance semi-conductor structure, and a resistance connected in series therewith, the resistor being formed by one of the regions of the semi-conductor body. As shown, an N-type wafer 37 of silicon is heated in an aluminium atmosphere to form diffused P-type layers 36. Four foil contacts 46, 48, 50, 52 are alloyed to the top and bottom faces, the first being of gold and antimony forming an emitter zone, and the others being of gold and boron forming ohmic contacts. The surfaces are waxed, scribed and etched with a nitric acid, hydrofluoric acid, acetic acid mixture to form grooves penetrating to the N-type layer 37 the grooves surrounding the respective pairs of electrodes. The device is seen to comprise an NPNP structure between electrodes 46, 50 in series with a resistance formed by the P-type material between electrodes 50, 52. The supply voltage is applied between electrodes 46, 52 and the trigger voltage between electrodes 46, 48; the read-out voltage is obtained between electrodes 46, 50. The resistance between 50, 52 may be adjusted by etching of the surface between electrodes 50, 52 until the desired characteristics are obtained. In a modification the resistance is formed between two electrodes on the upper side of the wafer, an ohmic connection being made between the emitter 46 and one of these electrodes. Other possible semi-conductor materials mentioned are germanium, silicon carbide and alloys of Group III (e.g. gallium and indium) and Group V (e.g. arsenic phosphorus and antimony). Dopants for silicon may be arsenic, antimony or phosphorus, for preparation of the N-type material, and indium gallium, aluminium or boron for forming the P-type layers. Photo-resist techniques may be used for etching the grooves. Diffusion and evaporation techniques may be used to form the various conductivity zones so that the abovementioned method forming the grooves need not be used. Specification 889,058 is referred to.
