Patent GB-2129172-A (GB)
Title: Data processing
Inventor: TUCKER CHRISTOPHER JOHN
IPC: G06F9/34
Filed: 1982-10-15
Abstract: Data presented (at 10) in the form of a sequential stream of digital words is processed by utilising one bit at a time of the same bit significance from each of a set of digital words (taken from registers 11-13) to access a location in a data store (14). The address location contains a required partial result and a partial address field. The latter is then used (via latch 18) in combination with bits of a different significance from the set of digital words to form a new address to access a different location of the store, which holds a required further partial result and another partial address field. The process is continued until all bits of the set have been dealt with and a complete result has been assembled (in register 20). The invention allows complex operations to be performed very rapidly on a large amount of data. The nature of the operations performed can very easily be altered by loading new information into the data store. <IMAGE>

Title: Television receiver standby circuit
Inventor: HAFERL PETER EDUARD
IPC: H04B1/034
Filed: 1983-01-25
Abstract: A deflection generator (21) of a television receiver includes a trace switch (27) that during normal mode of operation is switched at a deflection rate to generate scanning current in a deflection winding (LH). The deflection generator includes a retrace capacitance (CR) for forming a retrace resonant circuit with the deflection winding to produce a retrace pulse voltage. A load circuit (at Vb) is coupled to the deflection generator and is energized by the retrace pulse voltage during normal operation. A remote control circuit (30) develops a remote ON-OFF command signal. A standby circuit (Q2) is series coupled with the deflection generator (21) and is responsive to a remote ON-OFF command signal for producing substantially a short circuit through the trace switch (27) upon receipt of the OFF-state of the command signal. The retrace pulse voltage then collapses and places the load circuit in a standby mode of operation. <IMAGE>

Title: Electronic control system for a fuel pump
Inventor: MOORE JOHN HOWARD
IPC: F02D41/40
Filed: 1984-03-28
Abstract: An electronic control system for a fuel pump of an internal combustion engine includes a power circuit 18 which controls the flow of electric current in an electromagnetic device coupled to a spill valve 19 of the fuel pump. Power is supplied to the power circuit through a resistor 17 through which power is also supplied to an engine speed sensing circuit 15. The system also includes a control unit 14 which supplies variable duration control signals to the power circuit 18 to effect closure of the valve 19 and hence delivery of fuel, in timed relationship with the engine. The control unit receives the speed signal from the speed sensing circuit and also senses the voltage applied thereto. In addition it receives a demand signal from a transducer 16 and controls current flow in a relay winding 22 having contacts 21 in parallel with the resistor. In normal operation the contacts are closed but in a fault situation with the demand low and the speed high the winding 22 is de-energised and the voltage applied to the power circuit and speed sensing circuit falls below a standby level which is sensed by the control unit to maintain the winding de-energised. On starting the control unit 14 checks that the power circuit voltage is at the standby level before closing relay contacts 21. <IMAGE>

Title: Headlamp for motor vehicles
Inventor: LINDAE GERHARD
IPC: F21V29/15
Filed: 1984-10-26
Abstract: A headlamp with a primary reflector (30) constructed as a rectangular reflector, of which the short sides (34) of the upwardly directed exit aperture (32) is located parallel to the vehicle longitudinal median plane. Above this aperture a plane deviating reflector (21) with optical means (24) is present, which redirects the light into a dipped light beam or distance light beam and deviates the same towards the road. The primary reflector (30) may be pivoted out of the vehicle body (25) about a horizontal axis (37) placed underneath.   By this means the installational length in the direction of travel is reduced by approximately one third compared to a conventional headlamp, and the low temperature loading, due to the favourable heat dissipation out of the primary reflector, permits the use of thermoplasts for the production of the reflector. <IMAGE>

Patent GB-2166864-A (GB)
Title: Magnetometer
Inventor: JONES GRAHAM RICHARD
IPC: G01R33/032
Filed: 1985-08-06
Abstract: The magnetometer comprises a common light source 1 which feeds two Fabry Perot interferometers selected so that one experiences a path length increase due to a magnetic influence when the other experiences a path length decrease due to the same magnetic influence. A comparison between outputs of the two interferometers, as detected by photo detectors 7A,7B thus gives a measure of the magnetic field strength. This is independent of frequency or phase variations of the light source since such variations affect the two interferometers equally and these effects are therefore cancelled out in the comparison process. As shown, each interferometer comprises an optical fibre 5A,5B with half-silvered ends 6, one being clad in positive magnetostrictive material 5A' and the other in negative magnetostrictive material 5B'. <IMAGE>
