Patent GB-2233118-A (GB)
Title: Vehicle braking control
Inventor: MILLER GEOFFREY DENNIS
IPC: B60L15/20
Filed: 1990-01-12
Abstract: A vehicle 1 constrained to travel along a pathway 2, for example a train, is brought to a desired velocity (eg zero) at any advanced position 10. Knowing the velocity of the vehicle 1 at its present position 4, an automatic control system estimates the maximum velocity achievable at locations between the present position 4 and the advanced position 10 (eg from track gradient data) and determines an intermediate position 7 at which a service brake should be applied. If the actual velocity exceeds a calculated maximum allowable velocity at any position between the intermediate and advanced positions 7 and 10, an emergency brake is automatically applied. The maximum allowable velocities may be calculated by the control system from track gradient data and the braking characteristics of the vehicle in question. <IMAGE>

Abstract: A dual circuit hydraulic braking system with an anti lock system (ABS) and drive slip control (ASR) for motor vehicles has a four-channel hydraulic unit (20) with control valves (31-34), a return pump (27) with two separate pump elements (28, 29) for each brake circuit and two low-pressure accumulators (41, 42) connected to the inputs of the pump elements (28, 29). To supply brake pressure during ASR, at least one brake fluid accumulator (43, 44) is provided, which is connected to a pump element (28, 29) associated with a brake circuit containing at least one driving wheel (11, 13), and a switchover valve (38, 39) is disposed in each connection line (36, 37) between the master brake cylinder (15) and the output of such a pump element (28, 29). In order to achieve trouble free braking during ASR without risking unstable driving conditions, the brake fluid accumulator (43, 44) takes the form of an active controllable accumulator and the switchover valve (38, 39) is so designed that, in its switched-over setting, a non-return valve (40) whose blocking direction is towards the master brake cylinder (15) is effective. <IMAGE>

Title: Collapsible trolleys.
Inventor: KALOGROULIS ALEXANDER JOSEPH
IPC: B62B1/12
Filed: 1992-06-22
Abstract: A fabric bag is carried by an A-frame 1 formed by two legs 4 that splay apart from a handled housing 5 when the trolley is erected. The legs 4 are held-apart by an over-centre mechanism involving two struts 7 pivoted to the legs 4 and one another, and the resilience of the taut back-panel fabric 9 of the bag 2. A bottom panel of the bag 2 is strutted with rods 17 to stand out from the common plane of the legs 4 when they are splayed apart. Flexible-strand struts 26 strengthen the edges of side panels 15 to resist crumpling of the fabric when interlinked zip-fasteners on the front panel of the bag 2 are operated to open and close an access flap. A third leg 30 pivots in the housing 5 to form a tripod strut to support the inclined trolley. Collapse of the trolley (Figures 5 and 6) involves upward movement of the common pivot-point 8 of the struts 7, allowing the legs 4 to come together side-by-side with the leg 30, and the base panel 13 to fold with the front panel 18 overlying the side panels, on the legs 4. <IMAGE>

Filed: 1993-03-19
Abstract: A fluid control valve for central heating systems includes a valve body (10) having a fluid inlet (11) and a fluid outlet (12) communicating with an internal chamber (13). A primary valve member (15) is movable between a first position in which a primary valve aperture (14) is closed to the passage of fluid from the inlet (11) to the outlet (12) and a second position in which fluid may flow from the inlet (11) to the outlet (12).

Flow through lateral ports in the valve member (15), which connect the two separate volumes, is controlled by a disc 50 on a secondary valve member (17) positioned within the valve member (15). The primary valve member (15) has a drain aperture (33) which is opened when the secondary valve member (17) closes the lateral ports, so as to allow fluid in that volume of the chamber (13) remote from the primary valve aperture (14) to drain out and the primary valve member (15) to open. Electromagnetic means (18, 19) actuates the secondary valve member (17). <IMAGE>

Title: Emulating a disk store
Inventor: DREWRY JOHN ROGER
IPC: G06F3/06
Filed: 1993-05-17
Abstract: Data storage apparatus for emulating a disk store comprises a random-access memory having a plurality of addressable locations, each location holding a plurality of data bits and an address mark bit. A programmable read-only memory 22 converts a geometric disk address into a track base address indicating the location of the start of an emulated track within the random-access memory. A track position counter 30 holds a count value representing a current position along the emulated track. An adder 40 adds the count value to the track base address to generate a memory location address. If the address mark bit in the addressed location of the random-access memory is set, an output address mark pulse is generated, to indicate the start of a data block. The count value is compared at 34 with a track length value and, when they are equal, the track position counter is reset, thereby emulating completion of a revolution of the disk. <IMAGE>

Patent GB-2276419-A (GB)
Title: A diesel engine fuel injection system
Inventor: BRYER JOHN GAVIN
IPC: F02M25/07
Filed: 1994-03-28
Abstract: A needle lift sensor (38, Fig.2) generates a raw injector sensor signal which varies with the velocity of the injector needle. The raw injector sensor signal is integrated by the electronic control unit (ECU) 31 and the integrated signal used to generate a fuel quantity signal. The ECU uses the fuel quantity signal for an injection timing control by the pump 16 and/or an exhaust gas recirculation (EGR) control by the valve 26. The integrated signal may be compared in a look-up table or further integrated and compensated as necessary to provide the fuel quantity signal. The integrated signal may be held by a peak hold circuit and used with the duration of injection to provide the fuel quantity signal. The start of injection is derived directly from the raw injector sensor signal whilst the end of injection is derived from the integrated signal when it falls below a reference value. The ECU receives engine speed and temperature signals and a signal of the position of the valve 26 or exhaust recirculation flow. <IMAGE>

Title: Traction control in a four-wheel drive vehicle
Inventor: MATSUNO KOJI
IPC: B60W10/18
Filed: 1996-09-25
Abstract: Traction control in a four-wheel drive vehicle involves wheel braking and reduction of engine torque. A target slip for each wheel is determined at 31 in dependence on a reference slip, vehicle speed, actual yaw rate, and yaw rate deviation. When traction control is needed, as determined in judging section 32 by a comparison of the actual and target slip for each wheel, a signal is outputted to calculating means 33 which produces a braking force, according to the difference between the target slip and the actual slip, for each wheel and to calculating means 35 which produces a signal to the engine control apparatus 15 to reduce engine torque. The reference slip is that acheived by a wheel when in a straight running condition or in a neutral steer condition when executing a turn.
