Patent GB-2280571-A (GB)
Title: Signal transmission system
Inventor: MADDOCKS MARK CHARLES DOBELL
IPC: H04L27/26
Filed: 1994-07-07
Abstract: An improved system for transmitting a coded orthogonal frequency division multiplex (COFDM) signal is proposed wherein bits of data of most importance are coded into portions of the signal with greatest ruggedness, e.g. a QPSK signal. Bits of data of lesser importance are coded onto portions of the signal with less ruggedness, e.g. a 16 QAM signal. The resultant signal is transmitted. The peak to mean ratio of a signal for transmission is minimised by varying the amplitudes of carriers making up each COFDM symbol from symbol to symbol. At a receiver, (see figure 5), the thresholds for decoding anything higher order than a QPSK signal are computed by averaging the amplitudes of carriers in each quadrant of a phase diagram. In order to minimise interference to other transmissions the amplitudes of carriers within each symbol are varied such that the interfering contributions from each are equal. <IMAGE>

Title: Hydraulic governor for a fuel pump
Inventor: DANIEL JEREMY HOPLEY
IPC: F02D1/00
Filed: 1995-04-06
Abstract: A hydraulic governor for a fuel pump comprises a drum 30 attached to a drive shaft of the fuel delivery pump. The drum rotates within a housing 36 which has a step 38 formed by the interconnection of regions 36a, 36b. The region 36a has a relatively large area compared to region 36b. Fuel, due to its viscosity, tends to adhere to the drum 30 as it rotates which results in pressure being developed at step 38, as a consequence of fluid moving from region 36a to region 36b. The pressurized fluid enters passage 42 and acts on piston 44 having connected thereto a linkage 50 which controls a variable valve arrangement (52, fig 1). A governor spring 46 acts against the piston 44, the free end of the spring engages an adjustable stop (48, fig 1). The position of the piston 44 is thus dependent upon the pressure produced at the step and the prestressing of the spring 46. A viscosity compensator 60 is provided to account for viscosity changes in the fuel due to, for example, temperature fluctuations.

Title: Mach Zehnder modulator
Inventor: YU JUN
IPC: G02F1/015
Filed: 1995-06-28
Abstract: A MQW semiconductor Mach Zehnder phase modulator is formed by two Y-junctions (12, 32), each having a single waveguide (14) optically coupled with two branch waveguides (18, 20). The branch waveguides of the two Y-juntions are optically coupled in Mach-Zehnder configuration that, under zero bias conditions, has one interferometric arm longer than the other to provide a * small Greek pi * phase shift. The additional length is preferably accommodated in the branches of the Y-junctions. The phase shift, in combination with voltage dependent absorption properties and non-linear phase variations of the MQW guided regions in the Mach-Zehnder modulator results in a negative chirp and high extinction ratio for an equal, push-pull device configuration.

Title: Measuring apparatus
Inventor: COTTRELL BRIAN JOHN
IPC: G01K7/24
Filed: 1995-10-25
Abstract: The measuring apparatus is to be used in a programmable thermostat to provide information as to the actual temperature. The thermostat is provided with a microprocessor which controls the measuring apparatus which incorporates a resistive four-arm bridge circuit having fixed precision resistors (R1, R2 and R3) in three arms and a thermistor (RTH) in the remaining arm. To commence an actual temperature measurement, the microprocessor puts a voltage pulse across supply terminals (O, V<+>) of the bridge circuit and switches on two counters. The first counter counts the time for the voltage (VC) to rise to the thermistor voltage (VTH), whilst the second counter counts the time for the voltage (VC) to rise to the reference voltage (VREF). A ratio is formed of the two counts to provide a measure of the voltage (VTH) across the thermistor (RTH). <IMAGE>

IPC: H04N1/00
Filed: 1996-12-05
Abstract: A facsimile includes a printer with a recording element to print data and a temperature sensor to provide a sensing signal representative of the temperature of the recording element.
