Title: Tile product
Inventor: DIAMOND IVAN
IPC: E04F15/10
Filed: 1992-02-20
Abstract: A tile product (1) having a substantially non-porous vinyl composition base (2) and a multilevel embossing and gloss which has a mechanically embossed mortar-line surround and which is free of gloss defects formed by pockets of air trapped between the wear layer (3) and embossing mold during embossing is produced by applying a vacuum to the press during embossing.

Title: Optical detectionsystem protected against electromagnetic pulses
Inventor: GRANCOIN BERNARD
IPC: H01L31/0216
Filed: 1992-03-12
Abstract: This optical detection system includes a photodetector (1) placed in an enclosure (4) electrically continuous except for an input window (10) through which the optical radiation to be detected is transmitted to the photodetector (1). The protection of the optical detection system against electromagnetic pulses is achieved by the input window (10) including two parallel plates (5 and 6), spaced apart and transparent to the radiation to be detected, the space (7) delimited by the parallel sides of the transparent plates (5 and 6) and the edge of the conductive enclosure (4) on which the plates (5 and 6) are mounted being occupied by a rarefied gas transparent to the radiation to be detected in normal operation, and ionizable in case of an electromagnetic pulse to form then a continuous enclosure around the photodetector (1). Rapid ionization of the gas may be speeded up by providing a trace of radioactive material in the space 7 or by providing conductive strips on the inner faces of plates 5 and 8.

Title: Vehicle transmission assembly.
Inventor: WEISMANN PATRICK
IPC: B60K17/02
Filed: 1993-07-14
Abstract: A transmission assembly (14), particularly for a mid-engined car has a short longitudinal extent. The clutch output shaft (30) is connected by gears (32) to a transversely extending lay shaft (34) which engages a transfer gear shaft (36) which, in its turn, engages, and is arranged to rotate, a final drive gear (38). The axis of rotation (R) of the final drive gear (38) is substantially transverse to a longitudinal axis (L) of the transmission assembly (14), and the gears (32) are laterally offset relative to the longitudinal axis (L). Thus, the final drive gear (38) and the clutch assembly (22) overlap so that the length (F) of the transmission assembly (14) is very much smaller than is traditional. <IMAGE>

Title: Metal casting employing electromagnetic levitation
Inventor: BROOMFIELD M J
IPC: B22D11/01
Filed: 1994-02-08
Abstract: In a method for continuously casting a metal, a jet 18 of molten metal emerging from a crucible 12 is controlled by magnetohydrodynamic forces producing electromagnetic levitation provided by electrical coils 24. The jet 18 falls vertically and is levitated by a tubular linear induction motor 20 so as to fall at constant speed, while being cooled by a coolant sleeve 28 and by forced gas flow 36, 32, to emerge as a solid. The jet may be of circular cross-section, to form a rod 18, or of annular cross-section to form a tube 60. The forces maintain the desired cross-sectional shape of the jet and control the rate of flow of the jet. <IMAGE>

Patent GB-2302849-A (GB)
Title: Fire safety system for vehicle fuel tanks
Inventor: WAKEFIELD STEPHEN ROGER
IPC: A62C3/07
Filed: 1995-07-06
Abstract: The fuel tank has a system for fighting fires and/or neutralizing the fuel before a fire can start, in the event of an accident. The best example of this system is shown at figure 1 where a twin walled fuel tank 101, 102 has the space between the walls filled with a fire extinguishing/neutralizing substance. The inner of the two walls is weakened so that any impact upon the outer wall will cause a breech of the inner wall allowing stored fuels to be neutralized before an escape can take place from a breeched outer wall. The first substance to escape would always be the extinguisher/neutralizer since it buffers the stored fuels. Other examples show a system where extinguiushing/neutralizing substances are injected directly in to a single walled fuel tank to act on the fuel. This may be done using a multi-strand hose system (218, fig.2) connected to an extinguisher reservoir (204) via an impact-triggered valve (217), each hose having a series of holes (427, fig.4) along its length. Alternatively (fig.3), a perforated container (321) of extinguishant may be located in a casing (320) sealed to the wall (301) of the tank, the container being impelled into the tank by a spring (323) on impact.

Title: Container having means for guaranteeing the authenticity of origin of a product therein
Inventor: BOUNEAU FRANCOIS
IPC: B65D55/02
Filed: 1994-02-11
Abstract: The device is characterised in that sealing means (6b) are associated with means (10) for visually indicating the first opening of a container, which consist of an engraved inscription (11) straddling said sealing means (6d), once they are in place, and an immediately adjacent part (1a) of the container (1), so that the part (11a) of the inscription (11), which is provided directly in the material of the container (1a), is thereby made indelible, whereas the complementary part (11b) of the inscription (11) which is provided on an adjacent zone (6c) of the sealing means (6b) is removed during the tearing open of said sealing means when the container is opened, thus leading to an irremediable separation of the two complementary parts (11a, 11b) of the inscription (11), without the possibility of subsequently realigning them with a view to fraudulent re-use of the container (1). <IMAGE>

Patent GB-2304844-A (GB)
Title: Tyre valve connector
Inventor: VAN DER BLOM NICOLAAS
IPC: B60S5/04
Filed: 1995-09-12
Abstract: The connector 1 for inflation valves of vehicle tyres, consists of a housing 2, connected to a pressure source, having a coupling hole for securing to the valve and coaxial sealing of varying size in the housing with minor diameters approximately corresponding to the major diameters of valves for attachment in use, closest to the housing mouth having the largest diameter. In the housing 2 a piston 4 equipped with sealing 5, has or carries a pin 12 for actuating the tyre valve. Without any physical load, the piston 4 is held in a sealing longitudinal position against the housing bore, so that compressed air from a pressure source causes piston movement to actuate the valve. Bores 9, 10 in the piston 4 allow pressure air flow to and through the valve. In a retracted position, the piston 4 does not 100% seal against the housing bore. The pin can be separate from the piston, spring biassed forwardly and retractable by abutment of a pin (15, Fig.3) against a housing shoulder. The connector can be used with different types of tyre valve.

Title: Programmable logic array interconnections
Inventor: MCCLINTOCK CAMERON
IPC: H03K19/177
Filed: 1996-05-14
Abstract: A programmable logic array integrated circuit device has regions of programmable logic grouped in blocks disposed on the device in a two-dimensional array of intersecting rows and columns. Each block includes a relatively small number of logic regions to reduce the size and complexity of the local feedback circuitry required in the block. Interconnection conductors extend along each row and column of blocks. Some of these conductors are segmented along their length to permit independent use of each segment. When longer interconnections are required, however, adjacent segments can be interconnected by programmable bi-directional switches between the segments. Connections between the interconnection conductors and blocks may be programmable in two stages.
