Title: Fuel supply to EGR gases in a lean-burn auto-ignition i.c. engine
Inventor: MA THOMAS TSOI-HEI
IPC: F02M25/07
Filed: 1996-07-26
Abstract: Fuel is added by an injector 28 to the intake air and, to promote lean burn and auto-ignition at low engine load, fuel is also added by an injector 50 or by carburation (fig.1) to exhaust gas which is recirculated to the engine combustion chamber 10 via an external EGR pipe 30 in which the fuel is vaporised. It is ensured, eg by overall lean burn operation, that air is present in the EGR pipe 30 to mix with the vaporised fuel and the length of the EGR pipe 30 after the injector 50 (or carburettor) is extended to produce a substantial quantity of partial oxidation products and so that the duration of combustion at optimum spark timing is reduced by at least 10%. The exhaust gas may be stratified on entry to the combustion chamber 10. A controlled air supply 58 may be added to the recirculated exhaust gas and a high voltage wire 60 may ionise the exhaust gas/fuel mixture to increase the production of fuel radicals. Ignition in the combustion chamber 10 may be effected by compression at low load and by a spark plug at high load.

Patent GB-2330279-A (GB)
Title: Low power density radio systems
Inventor: GILES TERENCE GEORGE
IPC: H04L25/06
Filed: 1997-10-07
Abstract: A low power density radio system is achieved using a simple FSK transmitter arranged to transmit very short bursts to a receiver at frequent intervals. Such a system can be used between a meter transponder and a reader in an AMR system to eliminate the need for a receiver in the transponder and still achieve extended battery life. The problems of detecting and demodulating the short burst may be overcome by the use of a sample and hold circuit that detects a preamble of reversals to indicate the presence of the burst and to provide the reference value to correct for the DC pedestal voltage (26) that arises as a function of the transmitter and receiver frequency errors.

Title: A radio frequency mixer
Inventor: ERICKSON BRUCE A
IPC: H03D7/14
Filed: 1998-01-09
Abstract: A radio frequency mixer comprises a pair of alternately conducting diodes D1, D2 connected in series with a respective transmission line TL1, TL2. Superimposed RF and local oscillator signals are applied to an interconnecting node via an impedance matching network 3, 6a, 6b to minimize distortion. The mixer uses short transmission lines and terminating resistors to match impedances within the mixer and to minimize the mixer's distortion. A dumbbell shaped resonator 11 efficiently couples IF signals from transmission lines TL1, TL2 to an output transmission line TL3 at the mixer's IF output port. In an alternative arrangement (fig.3 not shown), the output transmission line may be centre-tapped to provide a pair of IF signals having opposite phases. The Rf mixer including the dumbbell resonator is constructed on a printed circuit board.
Patent GB-2329777-A (GB)
Title: Location system
Inventor: LLOYD PETER GREGORY
IPC: G01S1/04
Filed: 1998-01-14
Abstract: A sensor array comprises a number of detector elements which each detect radiation from a target. In order to determine the location of the individual sensor elements, each emits an individually coded chirped, spread spectrum signal in turn at a known time. Each detector receives the signals from the other detectors, and can determine the relative positions of the detectors from the difference between the times of transmission and reception; this gives relative rangers which can be stored, and the position can be determined by triangulation. Direction of arrival may also be determined.

Title: Toilet bowl ventilation
Inventor: OLOWU JONATHAN ADEYEMI
IPC: A47K13/30
Filed: 1998-10-30
Abstract: An extractor toilet seat which provides a convenient means of getting rid of foul odours from in and around the toilet bowl when in use. The seat comprises air ducts (2) on the under surface which lead to a hollow cavity inside the seat. An electrically powered, wall mounted extractor pump (4) provides the suction required via an air hose (3), (which is connected to the pump at one end and the rear of seat at the other), to extract the foul air. The air is sucked into the seat through the air ducts (2) and out of the seat into an air hose (3) through which it travels to the pump (4), where it is jettisoned out of the room via a hole in the wall, located behind the pump. A pressure switch (1) attached to the under surface of the seat activates the pump when the seat is in use and switches the pump off approx. 60 seconds after the pressure is released. Also attached to the under surface of the seat, are rubber cushions which protect the seat from breakage and create a small gap between the seat and the toilet, allowing fresh air to flow freely into the toilet bowl, thus replacing the foul air that has been extracted.

Title: Variable flow-restricting device and method
Inventor: JAKUBOWSKI JR THADDEUS
IPC: F16K3/08
Filed: 1998-12-10
Abstract: A variable flow-restricting and apportioning device for an aircraft ejector rack system having a pair of fluid-actuated thrusters includes a pair of rotatable feed conduits 30 for supplying pressurized fluid to the thrusters. Each feed conduit has an exit flow passage at its exit end 72 which is eccentric relative to the longitudinal axis about which the conduit is rotatable, and the exit end of each feed conduit slidably fits into a female receptacle in a receiver 34 in fluid commmunication with one of the thrusters.
