Title: Convertible vehicle seats
Inventor: BURGESS JOHN
IPC: B60N2/34
Filed: 1985-01-21
Abstract: A hatch-back vehicle is constructed and provided with means to form an uninterrupted level platform from facia to trailgate. The conversion can be easily and quickly effected for the 'passenger' side only thereby enhancing the vehicle's load capacity and providing a base for a full length sleeping bunk or for both sides of the vehicle thereby providing a double bunk (mobile tent) which can provide comfortable sleeping accommodation for two people. In this latter form the vehicle can form the basis of a frame tent by attaching an awning or extension to the raised tailgate.

Patent GB-2155220-A (GB)
Title: Electronic sound detecting unit for locating missing articles
Inventor: BAYER EDWARD B
IPC: G08B21/24
Filed: 1984-06-29
Abstract: A miniature, battery-powered electronic unit adapted to be attached to a common article such as keys or eyeglasses. The unit is responsive to a plurality of sounds for emitting audible tones to enable a misplaced article to be located. A sound detecting and indicating circuit provides the audible tones upon receipt of a sequence of sounds falling within predetermined frequency, time spacing and amplitude ranges. The correct sequence of sounds is generated by the user by clapping, whistling or making any other loud sounds, and no additional transmitting device is required. Improper sequences of sounds are prevented from producing false activation of the unit. Extremely low power consumption, resulting in part from CMOS technology, allows the unit to remain on continuously for a period of six to nine months using standard camera (button cell) batteries. Special battery-saver circuitry prolongs battery life. The unit can be fabricated using gate array or custom chip technology, which results in extremely small size and low cost of manufacture. A visual indicator (270) allows the user to learn proper operation.

Title: Electron multipliers
Inventor: SINK RONALD ALBERT
IPC: B01L3/00
Filed: 1986-09-19
Abstract: A microchannel electron multiplier is formed by placing into a glass tube (22) a plurality of bundles of optical fibres (16), each having an etchable glass core and a glass cladding which is non-etchable when subjected to the conditions used for etching the core material. The fibre bundles located around the inside surface of the glass tube are replaced by support fibres (24) having both a core and a cladding of a material which is non-etchable under the above-described conditions. The assembly of the tube, bundles and support fibres is heated to fuse the tube, bundles and support fibres together. The etchable core material is then removed and the assembly sliced into wafers. The inner surface of each of the claddings which bound the channel formed by the removal of the core material is rendered electron-emissive by reduction of the lead oxide by hydrogen gas. Metal films are deposited onto the opposed surfaces of each of the wafers to form contacts. <IMAGE>

Patent GB-2196009-A (GB)
Title: Structures of plastics material
Inventor: GREIG JOHN MARTYN
IPC: B29D23/00
Filed: 1987-08-17
Abstract: Large fittings or other structures are made by rotationally moulding a first component 18 of polyethylene and joining cylindrical pups 20, 22, 24 of polyethylene to the component by butt fusion joints 26, 28, 30. The structure within the boundary 50 is irradiated with gamma radiation followed by post-heating to remove free radicals. The extremities of the pups are shielded to prevent irradiation. Their capability to be joined to polyethylene pipes 12, 14, 16 by butt-fusion joints 32, 34, 36 is unimpaired. The irradiation introduces cross-linking to give improved properties such as impact resistance and stress crack resistance and to bring the fitting within the specification for polyethylene pipe for natural gas distribution. The joints 26, 28, 30 are made using differential heating of the ends to be joined to compensate for differences in melt flow index. Alternatively, the component 18 is slightly irradiated to lower its MFI before pups are joined to it.

Title: Load and synchronize computer architecture and process
Inventor: JOHNSON STEPHEN C
IPC: G06F9/46
Filed: 1989-02-22
Abstract: An architecture for a parallel processing computer system to implement a load and synch mutual exclusion indivisable operation is described. The individual processors have no special logic for implementing the instruction. However, additional circuitry in an interface unit and logic on the memory itself is used to detect and implement the indivisible operation. Thus, semaphore operations can be accomplished with a parallel processing computer architecture comprised of processing units that have no mutual exclusion primitives themselves. Each processor (as 50) uses virtual address mapping. A semaphore circuit 30 is coupled between the CPU and a multiplexer 21 for storing 31 the virtual address of the semaphore and the value 32 of the semaphore. A load and synch instruction stores the virtual address of the semaphore into the address decoder, 31, and retrieves an instruction from the semaphore value register, 32. <IMAGE>
