Patent GB-2052794-A (GB)
Title: Control of a fuel injection system
IPC: F02M51/04
Filed: 1979-11-20
Abstract: A fuel injection system includes a pumping apparatus having a component which moves during delivery of fuel. A transducer 61 provide a signal indicative of the position of the component. A differentiating circuit 73 and a fixed level or zero crossing detector 74 processes the signal from the transducer to detect the transition between a steady signal and a varying signal which may cross and thus vary in ad the opposite sense. The output from the level or zero crossing detector 74 is utilised as a timing feed back signal in a control means for an electrically operable means 46 the state of which is changed to effect delivery of fuel. In the combined fuel injector and pump a partial energisation of a winding is used to stop the return stroke of the pump when the detector outputs a signal indicating that the correct volume of fuel is drawn in. For injection the winding is given full energisation. <IMAGE>

Title: Muffle furnace
IPC: F27B15/16
Filed: 1980-03-26
Abstract: To achieve an effectively small furnace volume, with ease of control of atmosphere, in a through flow furnace, with the use of muffles, it is proposed to use a refractory muffle 6 comprising a base or hearth 8, side wall 9 and a roof 10 each made up of discrete elements of silicon-nitride-bonded silicon carbide.

For each electrode there is provided one or more respective light sensors in the optical scanner and electronic means controlled by a position encoder defines a succession of scanning intervals in which pulses are applied to the said electrodes when the output of the light-sensor or sensors exceed a predetermined threshold. Where there is a plurality of sensors associated with each said electrode, means is provided for condensing the outputs of the sensors so that the number of data channels emerging from the scanner correspond in number to the number of electrodes. Preferably the output of each sensor is compared with the threshold value to provide a logic output, which is then tested in an n-out-of-N logic encoding device. <IMAGE>

Title: Liquid admixing device
IPC: C02F1/68
Filed: 1981-05-21
Abstract: A liquid admixing device has an operating head (10) for mounting on a container (14) to contain liquid to be admixed and a pipe (24) for a carrier liquid under pressure, the pipe having an upstream tapping (20) into a bore (23) which leads to the container (14), to allow carrier liquid to be transmitted to the storage container. The pipe (24) also has a junction downstream leading from the container to allow the liquid to be admixed with the carrier liquid and thence expelled. An elastomeric membrane (15) is located in the container to separate the carrier liquid from the liquid to be admixed, pressure of the carrier liquid being transmitted via the membrane to force the liquid to be admixed into the pipe (24) via the junction (21). A shut-off valve (25), operable by the liquid pressure differences is provided in the pipe (24) to shut off supply of the carrier liquid once the liquid to be admixed has been exhausted or is running out. <IMAGE>

Title: Low capacitance self-aligned semiconductor electrode structure and method of fabrication
IPC: H01L21/335
Filed: 1981-12-22
Abstract: A semiconductor electrode structure with low parasitic capacitance is produced by a method for forming low capacitance first and second electrodes 34 24 in the semiconductor device, which may be a static induction transistor, while avoiding the requirement for precision mask alignment and mask to mask registration. During formation of electrode contacts, the first electrode 24 is protected by silicon nitride (22) and a low resistivity silicon layer (26) is grown over the semiconductor wafer, forming epitaxial regions (28) over the second electrodes (24) and a polycrystalline region (30) over protected portions of the wafer. The silicon layer is selectively etched by a mixture which removes the polycrystalline region (30) but does not appreciably affect the epitaxial regions (28). Second electrode metallic contacts are made in enlarged regions of the second electrodes where mask alignment is not critical. The reduction in contact window overlap by metallic contacts reduces parasitic capacitance. <IMAGE>
