Patent GB-2323709-A (GB)
Title: Pressure-sensitive switch
Inventor: HARDING PIERS SEBASTIAN
IPC: E05F15/00
Filed: 1997-03-25
Abstract: A pressure-sensitive switch comprises an elongate hollow body 10 having a region formed of an electrically insulating material 11 and having two or more spaced-apart regions formed of an electrically conductive material 13, the arrangement being such that, upon an external force being applied to the switch, the body deforms so that one electrically conductive region may contact another electrically conductive region thereby closing an electrical circuit. The hollow body 10 has a generally circular external cross-section and is suitable for insertion at any random orientation in a generally circular channel of an elongate sealing member. After the electrically conductive regions 13 contact each other, the hollow body 10 continues to be deformed during a limited period of overtravel. The shape and location of the electrically conductive regions 13 are such that the maximum degree of deformation of the hollow body 10, as measured by the amount of travel between two parallel planar surfaces abutting diametrically opposed regions of the hollow body 10, does not vary too significantly in dependence upon the particular angular orientation of the switch. The switch is used for preventing entrapment of objects in a closable aperture, e.g. windows, sunroofs and tailgates in automobiles.
Patent GB-2313005-A (GB)
Title: Memory repair multiplexer with reduced propagation delay
Inventor: DEAS ALEXANDER ROGER
IPC: H03K19/01
Filed: 1997-04-29
Abstract: The output 34 of a memory repair multiplexer 30 is fed directly to an output terminal 16a. After a short delay the output is buffered by enabling a non-inverting driver 36 coupled at its input and output to the multiplexer output node. The direct connection of the multiplexer output 34 to the output terminal 16a avoids the propagation delay of the driver 36. A data latch may be interposed between the multiplexer output 34 and the input of the driver 36 (figure 4), so that the circuit may be used in EDO mode SIMMs.
Patent GB-2325867-A (GB)
Title: Filter press with two lining membranes
Inventor: PIERSON HENRI GERHARD WILLEM
IPC: B01D25/164
Filed: 1997-06-02
Abstract: A filter press apparatus comprises a plurality of parallel filter plates 4 assembled as a unit 2 and located within a substantially rigid outer shell 8 to provide a closed vessel to which pressurised filtrand is supplied, and two impermeable membranes 18 and 24 lining the shell. The first membrane 18 is inflated by pressurised material between the membrane and the shell to form a incompressible boundary wall around the plates. The second membrane 24 has a intermediate extent 26 between the first membrane and the plates, and may have a slack extent 28 at one end of the shell. The second membrane reduces stress between the unit of plates and the first membrane upon axial compression of the unit, as the second membrane moves axially with the unit, sliding relative to the first membrane. The second membrane may be inflated by the introduction of liquid, which may or may not be pressurised, to the region between the two membranes. The press may have a hydraulic ram for compressing the unit of plates, the ram having a piston that extends axially into the shell to engage the endmost filter plate. The space between the second membrane and the shell may be filled with pressurised liquid to urge the second membrane into engagement with the piston to seal the piston within the shell.

Patent GB-2318186-A (GB)
Title: Operating a limit-current air/fuel ratio sensor
Inventor: TAKAMI MASAYUKI
IPC: G01N27/416
Filed: 1997-10-03
Abstract: An A/F sensor (30) is driven by a voltage applied thereto at a command issued by a microprocessor (20), and outputs an A/F detection signal which is linearly proportional to the concentration of oxygen. The applied voltage is determined by different rules inside and outside a predetermined air-fuel ratio detection zone (A/F 12 - 18). In the predetermined detection zone, the applied voltage normally has a positive characteristic inclined at Ri to the I axis. Outside the predetermined detection zone, the applied voltage is controlled either to limit the current signal to a predetermined value, preferably by using feedback or according to a different current-voltage characteristic from that inside the zone. Preferably, in a rich zone outside the air-fuel ratio detection zone, the applied voltage is controlled so as to make the applied voltage approach a maximum value (0.9V) of the electromotive force of the A/F sensor and in a lean zone outside the air-fuel ratio detection zone, the applied voltage is controlled so as to make the applied voltage approach a minimum value (0V) of the electromotive force of the A/F sensor.
Patent GB-2331266-A (GB)
Title: Over-moulding onto a pre-formed part
Inventor: LEGROS HERVE
IPC: B29C65/70
Filed: 1997-11-18
Abstract: A sealing, trimming or finishing strip, for use in vehicle body construction for example, comprises two strip members (5,6) such as made by extrusion from vulcanised rubber which are joined together by a corner piece (8) produced by an over-moulding process. The over-moulding process is a bi-injection process. It produces relatively hard thin layers (10,12) of thermoplastic elastomer which respectively form interfaces with the vulcanised rubber of the two strip members (5,6). Relatively soft thermoplastic elastomer material (14) is positioned between and interconnects the relatively hard layers (10,12). By ensuring that the only interfaces are between (a) between the vulcanised rubber of the strip-like members (5,6) and the relatively hard thin layers (10,12), and (b) between the relatively hard layers (10,12) and the relatively soft material (14), risk of subsequent rupture between the strip-like members (5,6) and the overmoulded part (8) is reduced.

Title: Dry storage vault
Inventor: BLACKBOURN MICHAEL
IPC: G21F5/10
Filed: 1998-05-29
Abstract: Canisters 400 are stored above ground in separate chambers of a concrete vault. The vault is constructed from pre-cast concrete sections 120, 140, 150. Each chamber has a stainless steel liner 450, defining inner and outer annular spaces 510, 520 between the hot canister wall 402 and the concrete wall 465. Cooling air flows through both spaces 510,520 by natural convection. Cold air flows in through base level vents 170. Hot air from the outer annular spaces discharges through upper vents 172 formed in the concrete and that from the inner space discharges through a gap 436 between a metal lid 430 and flanges 432, 434. Slots 532 are formed between inner and outer annular spaces to allow discharge of all hot air even if one vent is to become blocked. The concrete walls are cooled by further ducts formed as an integral part of the pre-cast structures.

Patent GB-2330977-A (GB)
Title: Video recorder/reproducer
Inventor: KOHRI TOSHIYUKI
IPC: H04N5/783
Filed: 1998-06-09
Abstract: A video recorder/reproducer for recording/reproducing video signals (SvN) inputted from n different cameras (CMn). A frame switcher (2) selects one of the video signals (SvN) sequentially in a specified order, and identification signal adders (10a, 10b) add identification signals (Sid) representative of the camera number (N) corresponding to the selected video signal (SvN), thus producing video signals (Sr1, Sr2). The video signals (Sr1, Sr2) are modulated by a record signal processor (11) and recorded on a magnetic tape (4) by magnetic recording heads (16a, 16b). A video signal (Sr') is reproduced from the magnetic tape (4) by means of reproducting heads (15a. 15b) and demodulated by a reproduction processor (14). A camera number detector (23) detects the identification signal (Sid) from a demodulated video signal (Sr2'). A memory (24) stores the demodulated video signal (Sr2') while correlating it with the detected identification signal (Sid). Therefore the picture from a desired video signal source is reproduced at a high speed or a normal speed without mixing the video signals from the n video signal sources.
