Title: Anti-skid brake control
Inventor: ARIKAWA TETSURO
IPC: B60T8/62
Filed: 1990-07-31
Abstract: In a vehicle braking system with a diagonally connected dual brake conduit system between front and rear wheels, speed sensors 28, 29 for each wheel, and a pressure control valve 4a, 4b in each conduit system, the pressure control valves are preferentially controlled by signals derived from the front wheels. However, when a brake control signal is generated by a rear wheel, it is used to control the respective control valve if the vehicle deceleration is high and if the vehicle is running straight, or the other rear wheel has high slip. Straight running may be determined by comparing wheel speeds, by comparing wheel and vehicle speeds or by a steering angle sensor. The valve control signal may be pulsed. <IMAGE>

Patent GB-2249690-A (GB)
Title: Security system for inspecting the underside of vehicles
Inventor: THOMSON RICHARD CHARLES
IPC: G06T1/00
Filed: 1990-11-07
Abstract: The underside of a vehicle is imaged by means of a sensor 1 located behind a lens 2 in a recess 4 in a speed hump or pit over which a vehicle may drive. The sensor images one complete sideways strip of the vehicle at a time, and this is read out as a line into a frame store. Successive lines are read into the frame store at a rate dependent upon the relative speed of the speed of the vehicle relative to the sensor. The speed of readout of the sensor may be reduced for the outer portions of the line compared to the central region in order to correct for distortion resulting form viewing the size of vehicle at an oblique angle. An undistorted image of the underside of the vehicle may be built up without interrupting vehicle flow. The image may be displayed or compared, by a computer, with an earlier image, or a standard image for the type of vehicle (determined by reading its number plate and consulting NVRC). <IMAGE>

Title: Controlling communications between master and slave stations
Inventor: KIMURA TAKASHI
IPC: B60R16/02
Filed: 1991-02-06
Abstract: In a system for controlling multiplex communication between a master station 10 and a plurality of slave stations 20, a predetermined signal (dummy signal) is transmitted to the plurality of slave stations via a communication circuit (serial bus) 5 from the master station when the master station does not (otherwise) communicate with any one of the slave stations. The predetermined signal indicates that the master station is operating normally, and each slave station receives the predetermined signal via the communication circuit so that each slave station may determine that the master station and communication circuit are operating normally. <IMAGE>

Title: Butt fusion heater releasable retention means
Inventor: HALLAM PETER JOHN
IPC: B29C65/20
Filed: 1992-01-20
Abstract: An apparatus for the butt-welding together of the ends of two plastics pipes (P) has two clamps (C) for clamping the respective pipes on each side of a heater plate (1). The clamps (C) are coupled through respective racks (8) to a pinion (6) which is rotatably mounted on a clamping block for movement of the clamps and therefore the pipes (P) towards and away from the heater plate (1). A retention mechanism releasably retains the heater plate in its operative heating position and is coupled to the pinion such that movement of the clamps away from the heater plate rotates the pin ion 6 in a direction to release the retention means and allow the heater plate to be withdrawn from its operative heating position so that the softened pipe ends can be brought together. Thus the heater plate is automatically released for immediate withdrawal as soon as the pipe ends are moved apart, enabling the jointing of the pipes to be effected as quickly as possible without undue cooling. <IMAGE>

Title: Faced fiber glass insulation
Inventor: MEIER SPENCER IVAN
IPC: F16L59/04
Filed: 1992-02-21
Abstract: An aircraft insulation product comprises a glass fiber blanket faced on at least one major face with an air permeable sheet. Insulating fibers (12) coated with unbonded binder are directed to a web (38) of the permeable sheet material supported on a moving collection chain (16), and the resulting fibrous layer and the web are sent to an oven (32) where the binder is cured. The collection web thus becomes bonded to the blanket by the binder to become an integral part of the insulation product. A plurality of stacked blankets, the edges of which are covered by a film, may be used instead of a single faced blanket. <IMAGE>

Title: Heatflow balancing thermometer
Inventor: FYFE ROBERT LENDRUM
IPC: G01K7/42
Filed: 1992-04-22
Abstract: A sensing surface 10 in contact with a medium or object whose temperature is to be measured is attached to a primary, thermally insulating support 11 which is mounted on a temperature-controlled, thermally conductive barrier 12. A heating or cooling device 22 and a secondary temperature sensor 23 are attached to the temperature controlled barrier 12. A pair of primary temperature sensors 20 and 21 are attached to the sensing surface 10 and to the barrier 12 respectively. The signals from the primary temperature sensors pass to an external control circuit, which regulates power supplied to the heating or cooling device 22 in such a way as to cause the temperature of the controlled barrier 12 to follow that of the sensing surface 10. This enables a secondary sensor 23 of normal size to measure quickly and accurately the temperatures of media and objects which are poor conductors of heat. A number of embodiments are described including one of sleeve form to fit around a tube containing fluid (Fig. 4); one intended for skin temperature measurement and having a tubular extension of the barrier 12 encircling the measured zone (Fig. 5); one for use as the wet bulb of a hygrometer (Fig. 6); and one in which the barrier 12 is extended to form a telescope tube capturing radiation from a remote body (Fig. 7). <IMAGE>

Title: Repelling permanent magnet motor with superconducting shields
Inventor: WHATFORD TREVOR LYN
IPC: H02K53/00
Filed: 1992-11-30
Abstract: A repelling permanent magnet motor comprises at least two sets of permanent magnets that oppose each other, of which one set is fixed to a shaft (the rotor) (A) and another set is fixed to the motor housing (the stator) (B). Superconducting shields (C) cover the magnets until one of the rotor magnets has just rotated past alignment with one of the stator magnets. At this point flux channels or holes (D) in the shields will come into line, exposing the magnets to repelling flux which will push the rotor magnets out of line with the stator magnets and close the flux channel. As one magnet leaves the cycle another one enters the cycle in which the flux channels are synchronized to open at the right time. A disc format allows multiple sets of magnets per stator and rotor and multiple sets of stators and rotors and shields per motor. <IMAGE>

Title: Power source switch circuit for TV or the like
Inventor: SUIZU KATSUTO
IPC: H04N5/63
Filed: 1993-03-11
Abstract: In a power source switch circuit comprising a first power circuit 3 fed from an alternating current source 1 when a main switch 2 is engaged, a second power circuit 5 fed from the main switch 2 via a sub-switch 4 and a control signal generator 9 operating when a voltage is fed from the first power circuits, detecting that the main switch 2 is switched on and generating a control signal for switching on the sub-switch, a further switch 11 is switched on with the main switch 2 and couples as a detecting signal a voltage stored by a first storing means 14 to a second storing means 15 which stores the detecting signal for a fixed period and controls the signal generator 9 so that the control signal to switch on the sub-switch 4 is produced. As the further switch 11 is only momentarily switched on when main switch 2 is turned on and remains off thereafter, if the AC supply is interrupted, when the AC supply is again supplied, no control signal is generated from generator 9 and the sub- switch 4 cannot be switched back on until the main switch 2 is again switched off and then on. The storing means 14 may be a battery. Storing means 15 is discharged via a resistor R3 and a transistor 16 which determines the fixed period. <IMAGE>
