Title: Improvements in or relating to Internal Combustion Engines Having Fuel Injection
IPC: F02D41/40
Filed: 1979-02-19
Abstract: Electronic apparatus for automatically adjusting the timing of the injection of fuel in a fuel injection internal combustion engine comprises a transducer for evaluating one or more operating parameters e.g. engine speed (10) load (11), temperature (12). The separate values sensed in operation by each transducer are fed to an electrical evaluating device (16) (e.g. a microprocessor) which gives a desired value output signal corresponding to the instantaneous optimum injection timing. An injection timing transmitter (15) produces an output signal giving the actual value of injection timing which is proportional to the position of an eccentric shaft (4) mechanically controlling the injection timing. When a difference arises between the desired value and actual value a control device (6) actuated through a power amplifier (7) is brought into use which adjusts the position of the eccentric shaft (4) as required and hence the injection timing. This correcting action is maintained until there is no longer any appreciable difference between the desired and actual values. The output of the injector (1) is controlled by an accelerator pedal which moves rod (8) through linkage (9) and the position of rod (8) is signalled by transducer (11) as a measure of the load on the engine. <IMAGE>

Title: Decoding arrangements for digital data
IPC: H04L25/45
Filed: 1979-04-18
Abstract: A decoding arrangement, suitable for use in digital data transmission systems, for decoding serial binary data in which 'one' and 'zero' binary values (41 and 40) are represented respectively by a voltage excursion of duration greater than and less than one half the bit period includes a counter which is arranged to count pulses (45) from an associated oscillator circuit upwardly for the duration of the voltage excursion and downwardly for the duration of the remainder of the bit period for each binary value received whereby the counter value at the termination of the counting operation for each binary value is indicative of whether that binary value is 'one' or 'zero'. The counter value is examined at the termination of the counting operation for each binary value and a signal provided representative of either 'one' or 'zero' as appropriate. The signal may be supplied to a shift register whose contents can be extracted in a parallel format. <IMAGE>

Title: Electrochemical machining aerofoil blades
IPC: B23H9/10
Filed: 1979-05-18
Abstract: An electrode assembly for electro- chemically machining an article, such as an aerofoil shaped blade for a turbo machine. The assembly comprises a plurality of electrodes 2, 3 for location adjacent a workpiece with root portion 12 and platform 13. Each electrode 2, 3 is constrained to move in a first direction towards each other and towards the workpiece and has two side members 22, 23 carried by a main body 21.

Title: A device for indicating the distance a vehicle can travel
IPC: G01F9/00
Filed: 1979-07-10
Abstract: A device for indicating the distance a vehicle can travel has three reference sources 2, 3 and 4 which supply signals dependent respectively on the speed 7 the remaining amount of fuel, and the fuel consumption of the vehicle, to a multiplexer 1. This switches between the signals and supplies each in turn to a counter 5 which counts pulses of the supplied signal over a time period, supplying the sum to a microprocessor 7 via a tri-state-buffer 6. The microprocessor uses the sums of the three signals to calculate the relationship speed multiplied by fuel quantity divided by fuel consumption. The result of this calculation is the distance the vehicle can travel. This result is then fed to a display device 9, via a driver stage 8. For convenience, the terminals of the microprocessor 7 are used for both output and input terminals, and the microprocessor 7 also controls the multiplexer 1, the counter 5 and the tri-state-buffer 6. <IMAGE>

Title: Anti-blow Out Slide Valve
IPC: E21B34/02
Filed: 1979-08-01
Abstract: The valve is designed to stop oil well blow outs. It is basically a slide valve cut in two along the axis leaving the closure mechanism complete on one half. Flanges are fitted to the two mating faces to enable them to be bolted together and semicircular flanges are fitted to the end of the valve to bolt it into place on an oil well pipe. Long arms are fitted to the end flanges so that the two parts of the valve can be hinged together. When an oil well blows out the lighter half of the valve is bolted onto the oil well pipe. The second half with the closure mechanism is hinged to the first part, swung into place and bolted securely. The valve can then be closed. This design allows a valve to be easily fitted without interfering with oil flow until it is closed. <IMAGE>

Title: A method of manufacturing a speaker diaphragm
IPC: H04R31/00
Filed: 1980-04-21
Abstract: A multi-layer compact block to be developed into a diaphragm having a honeycomb construction is initially expanded into a columnar block (8), and then the bottom (CB) of the columnar block (8) is radially expanded for obtaining a core of a speaker diaphragm. Thin layers are attached to the top and bottom of the core (11) to complete the diaphragm. The columnar block (8) may be expanded by means of a cone- shaped tool (9) into a truncated cone (8') which may be used to form a conical diaphragm. The truncated cone (8') may, however, be further developed into a flat disk by applying a force to the top thereof. Since the forces on expansion are applied to the block (8) uniformly, the density of hexagonal sections of the honeycomb construction is uniform throughout the entire circumference of the core thus providing superior speaker characteristics as compared with prior art which develops the multi-layer block fan-wise direct to a flat disk and consequently displays a non-uniform circumferential expansion. <IMAGE>

Title: Die casting method
IPC: B22D27/11
Filed: 1979-02-14
Abstract: Die casting method in which a molten metal is injected under pressure into a die cavity (30) through a sprue (31) and also applied with pressure through a pressure channel (17) communicated to the die cavity (30) at a location other than the sprue (31). To ensure the fabrication cation of products having no gross porosity, the application of pressure through the pressure channel (17) is commenced before the molten metal solidifies in the sprue (31) which is thus clogged. The pressure force is controlled such that an injection plunger (13) is not forced backwardly. The amount of the molten metal is also controlled such that the molten metal charged in the die cavity (30) is not displaced backwardly to the sprue (31) by the molten metal which is forced out from the pressure channel (17). This method is adapted to produce parts in which the air-tightness or precision working is required and the high pressure is applied thereto. <IMAGE>
