Abstract: 1325885 Fuel injection pumps AUTOMOBILES PEUGEOT 11 Sept 1970 [19 Dec 1969] 43568/70 Heading F1A In a fuel injection pump having a slide valve 17 controlling the quantity of fuel spilled from the pumping chamber 2 through a passage 26, 27, a fixed or variable volume deduction chamber 28 is in communication with the pumping chamber 2 and a discharge passage 31, 27 for the deduction chamber 28 is controlled by the slide valve 17. The slide valve 17 is reciprocated by a spring 18 and fuel pumped from an auxiliary chamber 11 into a chamber 15. The stroke of the valve 17 is controlled in a conventional manner by the position of a needle valve 22 linked to the engine accelerator pedal. Thus at full load neither passage 27 nor 31 is opened. At partial loads the passage 31 is opened for a short period to allow some emptying of the deduction chamber 28. Since at low loads the passage 31 is opened earlier, deduction increases with decreasing load. Because, for a given partial load the passage 31 is open for a time which decreases with speed, deduction decreases with increasing speed. The form of the chamber 28 may be as described in Specifications 1180630 and 1261246.

Abstract: 1309108 Treating semi-conductors INTEL CORP 22 Sept 1970 [24 Sept 1969] 45136/70 Heading H1K A stack of semi-conductor bodies separated by liquid permeable spacers is inserted into a bath of molten material which is isolated from the atmosphere and comprises a material which diffuses into the bodies. After completion of the diffusion treatment the bodies are removed from the melt and the adhering bath material removed. In the embodiment the bodies are of aluminium doped zinc sulphide and the melt of zinc. To reduce thermal shock the zinc is held just above its melting point in heated crucible 10 during insertion of the stack, which is disposed in permeable container 14. Loss of zinc vapour is reduced by plugs of quartz wool at 52 between crucible and container and at 48 in the mouth of the container between baffles 44, 46, The upper baffle 44 co-operates with a further baffle 62 to direct inert gas through aligned holes 58, 60 to isolate the melt from the atmosphere. After treatment at 800 C. for an hour the stack is removed and placed in a melt of indium or gallium. On removal from this melt residual metal adhering to the bodies is removed by wiping with quartz wool while the bodies are located on the heater and then etching in hydrochloric acid. In an alternative method in which the zinc is alloyed with indium or gallium the intermediate step of immersion in a gallium or indium melt is dispensed with. The apparatus may be modified to make the partitions slidably removable, and to dispense with container 14, and isolation from atmosphere may alternatively be provided by floating a layer of liquid boron oxide or solid particulate carbon on the melt. Suitable materials for the apparatus are quartz, graphite, vitreous carbon, boron nitride, alumina, zirconia and for lower temperatures heat resistant glass.
