Title: Electric circuit devices utilizing semi-conductive materials
IPC: H01L29/00
Filed: 1950-04-28
Abstract: 700,242. Semi- - conductor amplifiers. WESTERN ELECTRIC CO., Inc. April 28, 1950 [April 29; 1949], No. 10500/50. Class 37. An electric circuit device comprises a transistor in which the emitter electrode is in such close proximity to the base electrode that the base resistance is substantially lower than the emitter resistance. The arrangement provides improved stability and input impedance. In Fig. 1, a semi-conductor block 1 is provided with a base electrode 2 consisting of a metal film such as rhodium. The emitter electrode 3, which consists of a phosphor bronze wire, bevelled and such that it provides a minute contact area of elliptical shape, is placed very close (e.g..2 mil) to the edge of the base electrode. The collector electrode 4 is similarly shaped to provide a minute elliptical contact area. The metal film 2 may be situated in a recess in the semi-conductor body so that its surface is flush with the surface of the semiconductor, and the semi-conductor surface may be treated before assembly so that a thin P- type layer is formed on the N-type semiconductor block. Fig. 7 shows an alternative form of construction, the semi-conductor being in the form of a thin disc and one side of the disc being coated with metal to form a base electrode 24. The emitter electrode 21 makes contact through a small hole 25 in the metal coating, and the collector electrode 22 engages the opposite face of the disc. Alternatively the metal coating 24 may cover only half the disc surface, the emitter electrode being situated near the edge of the coating. In a further construction, the centre of the disc face bearing the metal coating is provided with a small central boss which penetrates the coating and engages the emitter electrode. A layer of polystyrene may be provided to cover the metal coating. In Fig. 10, a disc shaped block of N-type semi-conductor is provided with three raised portions, the central portion being in contact with a brass  rod 48 to form the base electrode, the raised inner ring forming the emitter electrode and the outer ring forming the collector electrode. The emitter and collector rings are formed of P-type conductivity material, which may be produced by nuclear bombardment, the resulting N-P junctions providing the rectifying contacts for these electrodes. Preparation of the semi-conductor material, including etching, washing, drying, grinding, sand blasting and electro-forming processes are described, and references are made to Specifications 694,021, 694,022, 700,232, 700,236, [Group XL(c)], 700,237 and 700,241.

Abstract: 975,668. Discharging dustbins into refuse vehicles. E. ZOLLER, and H. SCHULZZOLLER. March 18, 1963, No. 10535/63. Heading B8E. A dustbin discharging device on a refuse vehicle having a swingable front plate 2 and a closure flap 3 has a locking device in the form of a two-armed lever for automatically coupling the dustbin lid 8 to the flap 3 as the bin is swung into emptying position, as by an arm 4. The two-armed lever is pivoted on the flap 3 at 13 and one arm 12 engages the lid 8 as it is swung into position and causes the other arm 11, in the form of a stirrup, to hold a projection 9 on the lid. In a modification the stirrup 11 may be replaced by a hook to engage the lid handle and in another modification the twoarmed lever is differently mounted so that a hook thereon engages an eyelet on the bin lid as its first arm contacts the lid.
Patent GB-105609-A (GB)
IPC: E03D3/04
Abstract: 105,609. Doulton, H. L., and Walker, G. April 19, 1916. Valves closing after predetermined interval or flow.-Relates to a water-closet. flushing-valve of the type comprising a lift valve and double pistons controlled by a hand-operated pilot valve, such as L. The upper piston B is provided with three cupleathers V, X, Y, the last two fitting within the lower piston C and the first in the valve casing. In the closed position of the valve, the water pressure from E communicating through the passage F, control screw G, and control valve R, acts on the back of the pistons. On pressing down the valve L to open the main valve, the control valve R closes and the pressure behind the pistons is released through the passage J to the discharge K, and the pistons are moved up by water pressure. If the valve L is held down, the upper piston B remains up, but water pressure enters through the controlled aperture S between the pistons so that the lower piston C falls and closes the main valve within a desired time. When the valve L is subsequently released, the water pressure through the valve R, acting on the large upper surface of the upper piston, forces this piston down within a desired period for a subsequent opening of the main valve.

Title: A compressed-air control mechanism for use in connection with the brake cylinder or cylinders of railway, tramway, motor-road, and the like vehicles
IPC: B60T15/06
Filed: 1920-04-16
Abstract: 158,478. Harrop, A. T. April 16, 1920. Fluid-pressure.-Relates to fluid-pressure brakes of the kind in which the brake cylinder is provided with differential pistons the pressure on one of which is reduced to apply the brake, and consists in effecting the reduction in pressure by a compressor which discharges the air into a reservoir from which it is allowed to return to release the brake. In the running position shown in Fig. 2, both of the chambers 2, 8 in which the differential pistons 3, 4 work are subject to the pressure in the reservoir A so that the brakes are held off by the pressure acting on the larger piston 4. The pressure is maintained in the reservoir A by a compressor B and a valve V. As long as the pressure is at the required value, the piston V<1> of this valve is raised against the spring S as shown, so that the air is merely circulated from the reservoirs through the pipes 19, 18, the driver's valve C, pipe 20, and the compressor B. If the pressure falls by leakage, the piston V<1> of the valve V falls below the pipe 18 and the compressor then draws air from the atmosphere through ports 21 and pipe 18. To apply the brakes, the valve C is moved to connect the pipes 7, 20, whereupon the compressor draws air from the chamber 2 and compresses it into the reservoir A. When the desired application has been made, the valve C is moved to blank the port of the pipe 7 and to connect the pipes 18, 20 so that the pressure is maintained in the reservoir A and chamber 8 as in running condition. When the valve C is returned to the position shown in Fig. 2, air flows back from the reservoir A to the chamber 2 by pipes 17, 7 and the brakes are released. If the compressor or other part should fail, the brakes can be applied by venting the chamber 2 to atmosphere through the port 16 in the valve C. A non-return valve 10 is disposed in the pipe 9 leading to the chamber 8.
