Title: Improvements in or relating to an improved method of making electrical connections to semiconductor bodies
Inventor: CURTIS PETER BRYAN
IPC: H01L21/48
Filed: 1958-10-09
Abstract: 929,281. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. Oct. 7, 1959 [Oct. 9, 1958], No. 32251/58. Class 37. A method of making an electrical connection to a semi-conductor body comprises heating a metallic terminal of plate or strip form capable of being wetted by the fused semi-conductor in contact with the body to cause fusion of a restricted zone of the body adjacent to the terminal, heating being applied to the body by conduction through the thickness of the terminal, pressing the terminal against the body so that the terminal is displaced relatively to the body, ceasing heating when the terminal has been displaced to a predetermined position, and allowing the fused semi-conductor to solidify so as to effect a bond between the body and the terminal. The heating is preferably by means of an induction coil. The semi-conductor element 1 is placed in the lower end of a jig 2 the side walls of which are formed by two magnetic polepieces 3 energized by a horseshoe magnet 7. A passage extending through brass block 4 which acts as a stop connects the inside of the jig with a vacuum line 6 so that element 1 is held at the top of the jig. The polepieces 3 are insulated from magnet 7 and from brass block 4 and element 1 by mica strips 8, 14 and an iron terminal 9 bridges the polepieces. The vacuum chamber 10 is filled with argon. When the induction coil is energized, a localised region of semi-conductor body 1 is fused thus causing plate or strip terminal 9 to contact the polepieces so that lamp 13 lights; the induction coil is then switched off. Another terminal extending at right angles to the first is bonded to the opposite face of element 1. In making a thermoelectric device a number of semi-conductor elements are assembled in a rectangular array and connected electrically in series, adjacent elements being of opposite conducting type. The hot and cold junctions are on opposite sides of the assembly. Each element is a cube and has iron strip terminals on opposite faces thereof. The semi-conductor element is of general formula X 2 , Y 3 , where X is at least one of Bi, Sb, As and Y is at least one of tellurium, Se, S, e.g. bismuth telluride, antimony telluride bismuth selenide, and solid solutions of two or more of such compounds.

Abstract: 451,398. Safety devices for lift cages. WAYGOOD-OTIS, Ltd., Falmouth Road, New Kent Road, London. Nov. 22, 1935, No. 32394. Convention date, June 15. [Class 78 (iii)] Safety apparatus for a lift cage comprises jaws 58 which are pivoted on a member 55 slidably mounted on rods 100 suspended from the cage, and which, when brought into initial engagement with guide rails 16 effect movement of the member 55 towards the cage whereby the jaws are applied to the rails with a force due to the weight of the cage. When the speed of the cage becomes excessive, the governor 22 releases a catch 45 to permit clutches 33, 34 to fall and grip the governor rope 21, whereby a hitch 48 is released from a carrier 50 on the cage and a pull exerted on a rope 51. This rope, through linkages 107, 122, 123 and 112, 116, 117 respectively, effects upward movement of the member 55 on the rods 100, whereby levers 75 are rotated anticlockwise about pivots 81 to force wedges 71 between rollers 72 on the inner end of the jaws and apply shoes 64 to the guide rails 16. This retards the downward motion of the member 55 so as to bring it nearer the cage and cause the weight of the cage to be transmitted through springs 85 to the levers 75 to augment the force applying the shoes to the guide rails and eventually arrest the movement of the cage. The seats 159 of the springs may be connected together by linkage to ensure that equal forces are transmitted by the springs to the respective guide shoes. A buffer 135 is provided for engagement with an abutment 134 on the cage. The safety apparatus may be mounted on the counterweight of the cage. Specification 7759/92, [CLass 78], is referred to.

Abstract: 964,055. Fluid-pressure brakes. GENERAL RAILWAY SIGNAL CO. Aug. 23. 1962 [Sept. 18, 1961], No. 32412/62. Heading F2F. A brake control system for a train of vehicles comprises means for transmitting pulses of gas from one vehicle to the, or each other, vehicle of the train, and receiving means on each other vehicle responsive to the pulses of gas to control the operation of the brakes of that vehicle. As shown, in a convention braking system a brake pipe 10 is connected to a control apparatus 15 and has a branch 16 on each car extending to a triple valve 20, the latter connecting a brake cylinder 34 to a compressedair reservoir 22 on reduction of pressure in the brake pipe 10 brought about by releasing air by the control 32 through the exhaust 38. An auxiliary system for applying the brakes is provided and comprises a nozzle 44 through which short sharp pulses of high pressure gas from a reservoir 46 supplied by a pump 49 are introduced into the brake pipe 10 by an electromagnetic valve 45. A pulse coding and transmitting apparatus 50 is provided to control the energizing and de-energizing of the valve 45 and may be of any standard type that includes for example, shift registers which permit the energy to be read out and applied in serial form according to a predetermined code. Push-buttons A, B, C, D and OFF are used to select the particular code which is to be produced by the coding apparatus. The highpressure pulses in the brake pipe are sensed by a pneumatic pulse receiver and decoding apparatus 56 in the form of a pneumatic digital computer which is operated by air pressure from the reservoir 22. In accordance with the code received by the apparatus 56, depending on which button A, B, C, D has been pressed, each button corresponding to a different degree of braking, air pressure supplied by the reservoir 22 is introduced into one of the pipes 60, 62, 64, 66 to operate selectively a plurality of pressure-operated reducing valves 68 which allow air pressure to pass via conduits 36, 28 from the reservoir 22 to the brake cylinder 34 to apply the brakes to a predetermined degree. In response to the operation of the OFF button a code is sent which removes air pressure from those pipes 60, 62, 64, 66 which contained air to thereby cause the valve manifold 68 to exhaust the brake cylinder 34 via conduits 28, 36 to atmosphere at 70.

The lever 7 is biassed to the closed position by arranging the armature 13 nearer to the magnet 11 than armature 12. On increase of temperature, the collar 19 moves down, causing the member 16 to pivot on the plate 8 about the point 20, whereby a pip 17 on the member 16 presses on the lever 7 and contacts 14, 15 separate with a snap-action. On cooling, the pressure on the lever 7 is relieved until its tension is overcome by the magnet and armature 13 and the contacts reclose. The position of the armatures 12, 13 relative to the magnet 11 is adjustable by the contact 15, and a screw 21 controls the contact gap.

Abstract: 1471413 Vehicle headlamp adjusting system LUCAS ELECTRICAL Ltd 17 June 1974 [9 July 1973 1 Sept 1973] 32668/73 and 41240/73 Heading F4R In an arrangement for automatically adjusting motor vehicle headlamps in a vertical plane in response to the attitude of the vehicle in which the positional relationship between the vehicle body and wheels is sensed and from which a signal is derived which is damped to eliminate short-term fluctuations, there is also provided a mass, e.g. a pendulum arrangement, which is movable longitudinally of the vehicle body under acceleration and/or braking forces so as to produce an output signal dependent on the movement of the mass from a datum position, wherein the device for adjusting the vehicle headlamps is controlled in accordance with the damped signal as modified by the output signal. As shown, a pivoted lever arrangement 12-17 senses changes in the relationship between the vehicle body 10 and the rear axle 11 which changes are transmitted by a damped hydraulic system to a linkage 31-34 which is connected by a torsionally resilient bush 37 (Fig. 2) to a cross rod 36 on which the headlamps H are mounted. A pendulum 42 is also mounted on the cross rod 36 so as to be sensitive to vehicle attitude changes due to acceleration and deceleration, these effects being damped out as short-term fluctuations in the main part of the compensating system. The torsion bush 37 and rigid cross rod 36 may be replaced by a leaf spring arrangement. In alternative embodiments, Figs. 3 and 4 (not shown), an entirely mechanical system transmits the sensed vehicle attitude adjusting signals to the headlamps. In further embodiments, Figs. 5 and 6 (not shown), the function of the modifying pendulum arrangement is performed by a headlamp wiper motor (118) appropriately mounted on a cross rod (110) interconnecting pairs of headlamps (113, 114). In another embodiment, Fig. 7 (not shown), the pendulum arrangement is replaced by an arrangement which senses movement of the resiliently mounted cylinder block of the engine. Alternatively the modifying signal could be obtained from sensed movements of the vehicle transmission or of the seats therein.
