Patent GB-2245323-A (GB)
Title: Vehicle braking system
Inventor: YAGI EIJI
IPC: B60T8/26
Filed: 1991-06-14
Abstract: A vehicle braking system adapted to control brake forces at each of the vehicle wheels independently has a solenoid- operated shutoff valve (6) between a master cylinder (2) and a brake line (5) which includes a chamber (7a) of a modulating cylinder (7). A solenoid-operated flow control valve (9) controls the pressure delivered from an auxiliary source (12) to a control chamber (7b) of the cylinder (7). A control unit (13) controls operation of the shutoff valve (6) and flow control valve (9) in accordance with the vehicle running conditions e.g. as detected by pressure, steering, yaw, linear and lateral vehicle acceleration, vehicle speed and wheel speed sensors (15-22). The valve (9) controls the cylinder (7) to increase or decrease the brake pressure as required with respect to the master cylinder pressure and the reaction on the pedal is sudden, smooth or absent depending on whether the shutoff valve (6) is open, cycled or closed, respectively. The system may be used to effect differential front/rear or left/ right brake control. <IMAGE>

Abstract: Polyvinyl chloride or viscose rayon is laminated to leather by laying on a flat surface two sheets of polyvinyl chloride or viscose rayon placed face to face, coating the exposed surface of the upper sheet with adhesive, turning the sheets over adhesive side down onto a skin or split of leather on a flat surface, coating the upper side of the sheets with adhesive and turning the sheets and the leather layer over onto a second skin or split supported on a flat surface. The leather may then be buffed, cleaned up, and trimmed before opening up the centre of the product to produce two laminated leather products.
Patent GB-2252296-A (GB)
Title: Fluid sampling systems
Inventor: MASSIE KEITH JAMES
IPC: E21B49/08
Filed: 1991-12-05
Abstract: When sampling the fluids issuing from the geological formations into which a well, such as an oil well, has been drilled, it is highly desirable to bring the formation fluid to the surface in its original monophasic state. Various mechanical sampling arrangements have been proposed to ensure that this happens, and safely, but so far none have been entirely satisfactory. Both to keep the original state of the sample and to meet the requirements of avoiding the container bursting, there is required an arrangement that is in some way pressure compensated, so that as the container is lifted to the surface, and the ambient pressure and temperature drop, firstly the sample itself is sealed off to prevent it expanding (and separating) under the reducing pressure, and secondly the original ambient sample pressure is actually positively maintained despite any temperature change seeking to cause a corresponding pressure change (so that temperature-induced pressure drop and phase separation is avoided) even as there is provided the effect of a temperature-induced pressure-increase-absorbing gas cap without the actuality. This end, is attained by a sampler wherein the sample chamber (11), in which the sample itself is received and stored, is sealingly closed at one end by a movable partition (21) to the other side of which is applied either directly or indirectly (via a buffer fluid) a source of suitably pressurised gas. <IMAGE>
Patent GB-2254213-A (GB)
Title: Full-duplex optical transmission system.
Inventor: KWA PETER TJING HAK
IPC: H04B10/43
Filed: 1991-12-11
Abstract: An optical apparatus for transfer of full-duplex data signals over an optical waveguide 30 comprises electro-optic transducers 18, 26, coupled to the optical waveguide at opposite ends thereof. The electro-optic transducers are responsive, in a first mode, to drive signal pulses to produce transmit optical signal pulses for transmission along the optical waveguide and responsive, in a second mode, to receive optical signal pulses detected by the electro-optic transducer means to produce detected signal pulses. Drivers 142, 242 coupled to the electrooptic transducers, generate pairs of the drive signal pulses in response to each transmit bit of the data signals. Receivers 148, 248, also coupled to the electro-optic transducers, generate receive bits of the data signals in response to at least one of each pair of the detected signal pulses. A switch 143, 243 switches the electro-optic transducer means between the first mode and the second mode, couples the driver to the electro-optic transducer means in the first mode, and couples the electro-optic transducer means to the receiver in the second mode. The time delay between each pair of the transmit optical signal pulses differs from the time delay between each pair of the receive optical signal pulses, and the duty cycle of the pulses is limited so that at any point along the optical waveguide there is no interference between at least one transmit optical signal pulse and one receive optical signal pulse of each pair. <IMAGE>

Title: Band sizing and repairing device
Inventor: CHOU SCOTT M S
IPC: B25B11/02
Filed: 1991-12-19
Abstract: The device is provided with a base (12) and a plurality of blocks (60-63) rising from the base (12) for receiving and securing a watch band along its edge. The blocks (60-63) are separated by varying distances from each other to form channels of varying widths therebetween to accommodate watch bands of varying thickness. A pair of shoulders (26, 27) extend from one side of the base (12) and are separated from each other to form a gap (32) therebetween. A passageway in each shoulder (26, 27) permits a pair of bolts (51, 52) to extend through the pair of shoulders (26, 27). Upon rotation of the bolts (51, 52), a vice is formed wherein the passageways guide movement of the bolts (51, 52) therethrough in applying pressure to a pin of the band to insert or remove it. A hollow tip is provided at the inner end of at least one bolt (51, 52) so that the pin can be receivingly seated and held by the tip. Each block (60-63) also includes a receptor (71, 72) for seating a bit therein. The bit serves as a screwdriver to engage and thereby prevent rotation of a screw connecting the band to a watchcase when otherwise operating on the band. <IMAGE>

Title: A jewellery production process
Inventor: WHITE ROBERT
IPC: C23D3/00
Filed: 1995-04-21
Abstract: In production of jewellery there is a comprehensive metal preparation operation stage. This involves a dilute acid dip (25), a three-stage rinse (26), a concentrated acid dip (27), a hot rinse (28) and a drying stage (29). The concentrations and durations of these dips provide an extremely clean metal blank which is very suitable for reception and adherence of enamel. Enamel is wet-filled and there is direct flame heating for firing of the enamel. Both the enamel firing stage (32) and an annealing stage (24) are carried out by direct application of heat which has been found to be extremely effective and with a low defect rate. For plating, there is a sequence of steps involving a detergent dip (40), a rinse (41), an acid de-grease (42), and a rinsed step (43) which further prepares the jewellery item for nickel plating (44). After removal of all excess nickel the item is further plated, eg with gold.
