Title: Improvements in or relating to internal combustion engines and methods of operating them
IPC: F02B19/10
Filed: 1955-12-22
Abstract: 786,394. Regulating. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Dec. 22, 1955 [Dec. 24, 1954], No. 36765/55. Class 7(6) To ensure at all engine loads a constant rich mixture composition at the end of the compression period in an auxliary combustion chamber 3 having ignition means 25, the pressure of supercharging air delivered weakly carburetted at 6 directly to the main combustion chamber 1 acts to control the supply of fuel or air for the chamber 3. As shown, fuel only is supplied to the chamber 3, during the first half of the compression stroke, under the control of a pump 24 the operating cam 21 of which is slidable by a diaphragm 18 subjected to the delivery pressure of an exhaust turbine-driven super-charger 12 which may have a throttling valve 15 on its inlet or outlet side or a blow-off valve on its outlet side. A stop may be provided to ensure a small fuel injection into the chamber 3 when there is little or no supercharging. Instead of fuel, rich mixture may be supplied to the chamber 3, the air component being branched off from the output line of the supercharger 12 by a distributing valve controlled similarly to the pump 24. The invention is applicable to fourstroke engines or to two-stroke opposedpiston engines, and to single or multicylinder engines. Specification 722,044 is referred to.

Title: Improvements in or relating to the manufacture of semi-conductor bodies
Inventor: LEE MICHAEL ADRIAN
IPC: H01L21/00
Filed: 1962-09-27
Abstract: 1,027,496. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. Sept. 25, 1963 [Sept. 27, 1962], No. 36804/62. Heading H1K. The process of diffusing impurity material into a surface layer of a semi-conductor body so that the concentration of impurity material is substantially constant throughout most of the layer from the surface inwards, includes the three steps of heating the body with three different concentrations of impurity material at the surface, whereby the impurity material diffuses first inwardly, then outwardly and then inwardly again. In one embodiment, a wafer of Ge is subjected to antimony vapour in a heated vacuum chamber at 750‹ for 90 minutes. In three consecutive periods of 30 minutes each, the antimony present in the chamber is maintained at 550‹ C.; is rapidly cooled towards room temperature; and is heated to and maintained at 400‹ C. Antimony diffuses into the wafer during the first and third periods, and out from the wafer in the second period of much reduced external concentration of Sb. The resulting layer is of relative uniform impurity concentration to about 2À2 below the Ge surface. The wafer is then removed from the chamber and marked with wax on one major face whilst the diffusion layer is etched from the other faces. The exposed layer face is then soldered to a rectangular Ni plate serving as a base electrode with a central aperture therein. One spherical indium pellet is alloyed to the wafer through the hole in the Ni plate to form a P-type cylindrical emitter and another is alloyed to a central region of the opposite surface of the wafer to form a cylindrical collector. Excess indium serves as electrodes. After cleaning, the device is encapsulated in a hermetically sealed container. A further method referred to utilizes an added diffusion step after the formation of the relatively uniformly doped layer to form at the surface of the wafer a further layer of higher conductivity, giving a stepped impurity concentration profile: The emitter of this second type of transistor is formed in two parts, each in contact with one of the doped layers. Diffusion may be effected by use of a transport gas instead of by vacuum evaporation of heated impurity material.
