Patent GB-2342186-A (GB)
Title: I.c. engine with cooled exhaust gas recirculation (EGR) system
Inventor: COLEMAN GERALD N
IPC: F02D21/08
Filed: 1999-09-10
Abstract: Past exhaust emission control systems have failed to cool the exhaust gas prior to mixing with the intake air. The present exhaust gas recirculation system cools a flow of exhaust gas with a common coolant being used to cool an engine prior to mixing the flow of exhaust gas with a flow of intake air. The present exhaust gas recirculation system includes a control system for monitoring an operating parameter of an engine. The control system interprets a signal sensing the operating parameter within a controller and the controller causes an exhaust valve regulator to move between an open position and a closed position. Additionally, a plurality of paths or maps, for example, one being a normal coolant temperature strategy and another being a high coolant temperature strategy is used. In the normal coolant temperature strategy, with the exhaust valve regulator in the open position the supply of fuel to the engine would be advanced. In the high coolant temperature strategy, with the exhaust valve regulator in the closed position the supply of fuel to the engine would be retarded. Thus, the emissions emitted from the engine are maintained within a preestablished parameter.

Title: A parallel optical fibre amplifier
Inventor: PARK NAM-KYOO
IPC: H04B10/294
Filed: 1999-11-23
Abstract: A parallel optical fibre amplifier comprises first and second erbium-doped amplifier stages (EDFA) 110, 120. There is a means for re-using spontaneous emission light emitted from the first EDFA 110 stage as a secondary pumping source for the second EDFA stage 120. The second EDFA stage 120 may comprise; an optical pumping means 126, a first optical fibre portion 124 which is optically pumped, and a second optical fibre portion 122 which is not optically pumped. The spontaneous emission light from the first optical fibre portion 124 may be re-used as a pumping source for the second optical fibre portion 122. The first and second stage EDFA's may be either a C-band or an L-band EDFA. The re-using means may comprise; a circulator 150 for receiving spontaneous emission light from the first EFDA stage 110, a connecting optical fibre 160 for transmitting the received spontaneous emission light to the second EDFA stage, and an optical WDM coupler 170 connected between the connecting optical fibre 160 and the second EDFA stage 120. The optical fibres amplifiers may be silica-based. Preferably, amplified spontaneous emission (ASE) light from a C-band EDFA stage and reverse ASE light emitted from an L-band EDFA are re-used in the L-band EDFA stage.

Title: Device for detecting rotation, in particular to volumenometry
Inventor: BINKLE MARKUS
IPC: G01P3/48
Filed: 1994-01-25
Abstract: The detector contains a rotor with angular division into several regions with different electromagnetic damping properties opposite sensors forming elements of an oscillator circuit. The oscillations are damped as the rotor turns. The oscillator output signal is fed to a discriminator circuit which measures the rotor rotations and can also measure its rotation direction. Two sensors can be used. A reference sensor (RS) is arranged opposite a region of the rotor with constant damping properties. The other sensor, i.e. the measurement sensor (MS), is arranged opposite an odd number of regions (d0-d2) of the rotor with different damping properties.
