Abstract: 1,239,235. Variable resistors. NIPPON KOGAKU K.K. 24 Oct., 1968 [24 Oct., 1967], No. 50558/68. Heading H1S. A variable resistor for use in measuring instruments comprises an insulating plate 1 on which is formed a lower layer of a base metal for example chrome, titanium, manganese, beryllium, tantalum or nickel or an alloy thereof and an upper layer of palladium film on which a sliding contact 4 for example a phosphor bronze wire is engaged. Alternatively a further film of the base metal mixed with palladium may be sandwiched between the upper and lower layer so as to gradually reduce the concentration of palladium from the upper surface and hence achieve a reduced temperature coefficient of resistivity. The films are deposited by sputtering, and the shape of the films can be adjusted to achieve the required characteristics. In an arrangement which may be added or alternative to the above palladium over chromium layers forming parallel spaced-apart strips have on them or under them a further thin film or resistive layer having a higher resistivity than the strips. The sliding contact is of such a size that it is capable of bridging the gap between adjacent strips (Fig. 3, not shown). The layers may be covered with silicon oxide.

Abstract: 1296284 Controlling I.C. engine FORD MOTOR CO Ltd 27 Oct 1970 [14 Nov 1969] 50930/70 Heading F1B A process for operating a spark ignition fuel injection I. C. engine during idle speed and part throttle conditions includes inducting fresh air into each cylinder with a motion to promote mixing, injecting fuel into each cylinder late in the compression stroke, so that in the combustion zone at the time of ignition the mixture is rich, whereas the overall air fuel ratio in the cylinder is lean, and throttling the air to maintain a constant air fuel ratio. Some of the exhaust gases may be recirculated during part throttle operation. An I.C. engine fuel pump 4 is regulated between a maximum fuel-flow position 22 and a minimum (which may be zero) position 18, the normal idling position being 20, by a lever 16 controlled by a servomotor 38, connected by conduits 62 and 64 respectively to points upstream and downstream of a throttle valve 34. The servomotor 38 comprises a piston 40 having a flexible diaphragm 48 separating chambers 44 and 46, a diaphragm retainer 52 seating a compression spring 70 which has a small preload, the other end of spring 70 seating on a holder 72, normally maintained in the position shown by a preloaded deceleration cut-off spring 76 having a very soft rate. A constant air fuel ratio spring 80 is mounted on a seat member 78 attached to holder 72 and does not normally contact retainer 52. When the throttle valve 34 is wide open, the pressure difference between chambers 44 and 46 is insufficient to overcome the preload of spring 70, so lever 16 is held in the position shown. As the throttle valve is closed, the pressure difference between chambers 44 and 46 causes piston 40 to move against spring 70 reducing the fuel supply so that the air fuel ratio increases. Once spring 80 is engaged by the piston, the air fuel ratio remains constant until lever 16 reaches idling position 20. Under deceleration from speed, the large pressure drop across valve 34, causes spring 76 to be compressed, allowing lever 16 to reach minimum fuel-flow position 18.
