Title: I.c.engine fuel supply and recirculation system
Inventor: CHAPMAN PETER GEOFFREY
IPC: F02M37/10
Filed: 1995-08-04
Abstract: Fuel supplied from the tank 11 by the electric motor driven feed pump 14 or an engine driven feed pump to one end of a duct 20 supplying one or more fuel injectors 18, e.g. combined pumps and injectors, is recirculated through the line 34 from the other end of the duct by a pump 33. The pump 33 may be an injector pump, a separate motor driven pump (33A, Fig. 2) or a pumping element (133, 233, 333, Figs. 3 to 6) driven by the feed pump drive. An injector pump 21 operated by returned fuel passing through the line 19 draws fuel from the tank 11 into an auxiliary reservoir 13 with a perforated baffle 24 which prevents flow of air bubbles to the feed pump 14. The pressure in the line 19 is maintained by a regulator 28. A heat exchanger (335, Figs. 5 and 6) with a thermostatically controlled bypass (337), a pressure regulator (328) and a filter and air separator (332) may be provided in the recirculation line (334). <IMAGE>

Title: Back bias voltage detection circuit for semiconductor memory device.
Inventor: KIM HONG SEOK
IPC: G11C5/14
Filed: 1995-09-12
Abstract: A back bias voltage detection circuit for a semiconductor memory device comprises back bias voltage detection means (12) for detecting a back bias voltage. The back bias voltage detection means (12) comprise an NMOS transistor (MN2) having a threshold voltage varied by variations in the back bias voltage. Variable resistor means (11) are provided for amplifying the back bias voltage. The threshold voltage of the NMOS transistor (MN2) is detected on the basis of a reference voltage (Vref) applied to its gate, and the back bias voltage is adjusted according to the detected threshold voltage. With the back bias voltage adjusted, the threshold voltage of the NMOS transistor can efficiently be controlled. Therefore, the back bias voltage detection circuit can readily detect the back bias voltage and enhance its operating speed. <IMAGE>

Title: Method of power conservation in a data communications system
Inventor: RUSSO DAVID
IPC: H04W52/02
Filed: 1995-11-22
Abstract: In a data communications system including an infrastructure and a subscriber unit operating with a protocol that mandates proactive scanning, a method of power conservation practiced at the subscriber unit including monitoring a registered data channel during an active time period (403), assessing the data channel during the active time period to provide a channel quality value (407), comparing the channel quality to a first threshold (413), assuming a sleep state when the channel quality satisfies the first threshold (417), and scanning another data channel for another channel quality value that satisfies a second threshold when the channel quality does not satisfy the first threshold (415). The channel quality value may be obtained by assessment of received signal strength or bit error rate or by a combination of both. <IMAGE>

Patent GB-2310038-A (GB)
Title: Accelerometer and displacement sensor
Inventor: JENKINS JOHN GRUFFYDD LLEWELYN
IPC: G01P15/08
Filed: 1996-10-14
Abstract: A solid-state displacement sensor or accelerometer comprises an input transducer 10 coupled to one end of an elongate semiconductor waveguide 11, and a detector 12 coupled to the opposite end of the waveguide 11. In use, a continuous or pulsed electromagnetic, acoustic or pressure wave is applied to the waveguide 11 by the input transducer 10. When the sensor is displaced, the effective path length between the input transducer 10 and the detector 12, as seen by the wave propagating along the waveguide, varies along the axis of the waveguide and this momentary change in effective path length can be determined by measuring, for example, the corresponding change in amplitude, phase, frequency or transit time of the detected wave, in order to give a measurement of the displacement of the sensor. The acceleration of the sensor can then also be determined as a function of displacement with respect to time.
Patent GB-2319908-A (GB)
Title: Starting and direction control of two phase switched reluctance machine
Inventor: WILLIAMS BARRY WAYNE
IPC: H02P1/16
Filed: 1996-11-28
Abstract: A method of starting a two phase switched reluctance machine 5 and direction control is achieved by sequencing the order by which the phase windings are energised. This includes the use of two-phase 'on' condition, which, when rotor poles are aligned with a set of stator poles, results in an asymmetric magnetic field. The start up sequence comprises energising one of the phase windings with a prescribed current magnitude and direction, after a prescribed time period, the remaining phase is energised with a prescribed current magnitude and direction, and after a prescribed time period with both phases energised, one phase current is de-energised such that torque is produced and the rotor rotates in the desired direction. Direction control from the position achieved with both phases 'on' is simply the case of turning one phase off. The method uses a sequence controller 4 and may use some form of shaft position control to control commutation. An optical or magnetic sensor 6 is described (Fig 8). Starting may be enhanced by using asymmetry in the machine design by wedges on the rotor poles (Fig 9) or by using a non-salient stator configuration by arranging the phase conductors (N1 and N2, Fig 10) in slots of the stator.

Title: Combustion control method
Inventor: KIM SI-HWAN
IPC: F23N3/08
Filed: 1998-05-28
Abstract: A combustion control method for a gas boiler establishes reference wind pressure, reference fan driving voltage, and reference flame voltage in an initial ignition time. The established reference wind pressure is compared with the wind pressure from sensor 250 in the present state. A fan driving voltage is changed according to the comparison result of the wind pressures. The fan driving voltage is changed to track the flame voltage from infrared sensor 200 in the present state to the reference flame voltage. When the flame voltage in the present state reaches the reference flame voltage, a normal fan driving voltage is set to the fan driving voltage at that time, and a normal flame voltage is set to the flame voltage at that time. Under the establishment of the normal fan driving voltage, the flame voltage in the present state is compared with the normal flame voltage. According to the comparison of the flame voltages, the fan driving voltage is changed so that the flame voltage in the present state follows the normal flame voltage.

Title: Method for determining the active power of asynchronous electric motors
Inventor: WEIGEL WILFRIED
IPC: G01R31/34
Filed: 1998-09-17
Abstract: A method for determining the active power (P) of asynchronous electric motors (16, 17) of winning and conveying equipment (10) in underground mining. According to the invention, particularly easy and accurate determination of the instantaneous active power of the motors is obtained by storing the individual motor characteristic (P(n); M(n)) of each motor in a computer (25), by detecting the instantaneous speed (n, n') of the motor with the aid of a tachometer (20, 22; 21, 23) and by comparing this speed with the characteristic stored in the computer, the active power being derived from the torque value or power value assigned to the detected instantaneous speed, as stored in the computer. This particularly rapid and simple calculation of the power value does not require any readings to be taken at the power supply to the motors.
