Abstract: 757,536. Semi-conductor devices. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 2, 1955 [Feb. 3, 1954], No. 3232/54. Class 37. A semi-conductive device has voltages applied across and longitudinally of a PN junction and the latter is triggered to the conducting state by a light pulse. In Figs. 2 and 3 an N type germanium wafer 10 comprises ohmic end contacts 11, 12, and a central P type zone A pro. duced by diffused indium pellet 13. A battery 14 produces a potential gradient along the germanium wafer 10 and the PN junction is just biased inversely by battery 17, i.e. the P type zone A is just negative with respect to the N type germanium immediately opposite, so that zero current flows through relay 19. If a -light beam 18 is directed on to the PN junction hole emission will start from the P zone and rapidly build-up and the resulting current through the PN junction operates relay 19. The construction of Fig. 4 shows the wafer 10 supported by ohmic contacts 11, 12 on to wires 21, 22 which pass through glass-metal seals on to a metal base 23. The required contact to the pellet 13 is made by soldering on an electrode which is fixed to the base 23. A cap 24 .comprising a window 25 (e.g. light filter or lens) is sealed to the base 23. In a modification, Fig. 5, the wafer 10 is mounted with pellet 13 on the underside so that light from window 25 is transmitted through the small thickness of the wafer 10 to the PN junction. The invention may be performed using a P type wafer (silicon is mentioned) with arsenic as diffused pellet to produce an N type zone. Specification 728,129 is referred to.

Title: Improvements in and relating to the lubrication of internal combustion engines
IPC: F16N13/16
Filed: 1955-02-04
Abstract: 834,533. Lubricating. KYLE, D. W. E. Jan. 24, 1956 [Feb. 4, 1955; Oct. 11, 1956], Nos. 3423/55 and 29000/55. Class 12 (3). A method of lubricating the working cylinder of an internal combustion engine comprises injecting lubricant into the cylinder at a position a little below the head of the piston at substantially the end of the compression stroke under a pressure exceeding the pressure in the cylinder. The lubricant may be injected into the cylinder by at least one pump actuated by fluid pressure available on the engine but high enough to enable the lubricant to be injected at a pressure higher than the compression pressure in the working cylinder. The fluid pressure may be the pressure of the fuel supply to the fuel injection nozzle. In the apparatus shown in Fig. 1, a piston 11 works in a cylinder 12 to which either fuel under pressure or air from the head of the working cylinder is admitted. A crosshead 13 extends over plungers 14 mounted in a block 16 and working in bores 15 as lubricant delivery pumps. Aligned with the bores 15 are bores 17 containing plungers 18 which form parts of metering pumps. The delivery stroke of these pumps is effected by a platen 19 connected to the crosshead 13, the platen carrying forward the plungers 18. The suction stroke of the plungers may be varied by means of flanges 22 on sleeves 23 screwing into the block 16 and co-operating with collars 24 on the plungers 18. The springs 231 effect the suction stroke to cause lubricant to be drawn through sight glasses 33 and pipes 32 and past valves 25 into the bores 17, from which lubricant is drawn, past valves 26, on the suction stroke of the plungers 14 to be delivered past valves 27 and through delivery pipes 31 leading to points in the working cylinder. The sight glasses 33 are supplied with lubricant from a reservoir 34 in which the lubricant is kept at a constant level by a float valve 35. In the construction shown in Fig. 2, a number of pumps are arranged in the base of a container 41 for lubricant. Along the front is a bar 42 with a passage 43 connected with the fuel supply leading to the injector of the associated working cylinder. The fuel has access to a row of pistons 44 which through tappets 45 act upon metering pump plungers 46. Each plunger acts against the plunger 53 of a lubricant-delivery pump provided with a spring- pressed delivery valve 54. The metering pump draws lubricant from the bottom of the container 41 by uncovering a port 79, the lubricant passing a ball valve 65 and through a port 81 and passage 82 to the upper end of a sight feed glass 47 in which an air cushion is trapped. The outlet from the feed glass leads through passage 55 to a port 78 which is uncovered upon return movement of the delivery pump plunger 53. Forward movement of the plunger forces the lubricant past the valve 54 and out through pipe 77 to the working cylinder. A lever 56 may be provided for each metering pump to enable it to be operated independently of the fuel plunger.

Filed: 1936-02-05
Abstract: 465,300. Light - current relays. GENERAL ELECTRIC CO., Ltd., and ROSE, W. R. Feb. 5, 1936, No. 3429. [Class 38 (v)] A relay of the type in which the armature is held in either of two positions without energization of either of two operating coils, comprises two magnetic circuits each composed of an operating coil and core and a yoke and armature, the said magnetic systems being disposed side by side and the two armatures being interlinked by a rocker extending from one to the other and pivoted about an axis passing at right angles through a line drawn parallel and midway between the axes of the operating coils, the armature last operated being held in this position by interaction between an arm carried by the rocker and extending between the magnetic assemblies and a flat bowed spring, compressed between a V-notch at one end and a further flat spring at the other. As shown in Figs. 1 and 2 the two operating systems each consisting of winding 1 core 3 and L-shaped yoke 2 are mounted side-by-side on a bar 7, the armatures, pivoted on knife-edges formed on the yokes, being interlinked by a rocking member 9 pivoted on a pin 10 carried by a member 6 extending between the operating systems. Carried by the member 9 is an arm 14 the forked end of which engages the side of a bowed spring 13 supported between a V-notch formed in the upper part of the member 6 and a slot in a pin 17 slidably mounted in the lower part of the member 6 and acted upon by an adjustable blade spring 20. Thus when either armature is attracted by energization of its corresponding electromagnet it rocks the bar 9 to cause positive release of the other armature. Also during this movement the bowed spring 13 is moved by the arm 14 to its opposite bowed position and by reaction retains the armatures in their displaced positions. Either or both of the armatures may control contact springs. Adjustments to provide for variation in the core lengths and eccentricity of the pin 10 are provided. Specification 354,847 is referred to.
