Patent GB-2154651-A (GB)
Title: Key-operated security mechanism
Inventor: CRITCHLEY ALAN
IPC: E05B17/22
Filed: 1985-02-12
Abstract: To combine the operation of locking a container 10 with switching on and off equipment inside the container, bolt element 11 inside the container 10 is movable, by a key 15 inserted from outside, between a first position (not shown) in which equipment switch 16 is actuated and a second position (not shown) in which it is not. In both positions the container 10 is locked by engagement of the bolt element 11 with a locking member 17. The element 11 is also movable to a third position (Fig. 2) in which the equipment is switched off and the container lid 13 can be opened. <IMAGE>

Title: Heat-shrinkable elastomer production
Inventor: MATRAY ATTILA
IPC: B29C48/08
Filed: 1985-05-01
Abstract: A method of producing a heat-shrinkable elastomer comprising the steps of: (a) without the application of external heat, extending an elastomer comprising a copolymer of alternating polyamide and polyether repeat block polymer segments to an extension beyond that at which permanent deformation occurs thereby to orient said elastomer uniaxially, and (b) subsequently releasing the tension on said elastomer to allow natural relaxation thereof to a linear density substantially above the minimum linear density achieved in the extension of step (a) and substantially below that of said elastomer before the extension of step (a). Upon subsequent application of heat, the elastomer shrinks and recovers its elastic properties. Articles or garments such as disposable diapers advantageously use the heat-shrinkable elastomer of the present invention as a means to shirr portions thereof, such as waistbands.
Patent GB-2158265-A (GB)
Title: Sample carrier for flameless atomic-absorption and emission spectroscopy
Inventor: LERSMACHER BERNHARD
IPC: G01N21/74
Filed: 1985-05-01
Abstract: The sample carrier consists of expanded graphite cold-rolled or cold-pressed at high pressure. It is preferably made by deep-drawing from commercially available graphite foil. The sample carrier may be coated with pyrolytic graphite after forming to seal the surface and provide additional mechanical strength. In order to avoid damage to the foil during the deep-drawing process the graphite foil may be prior coated with a stabilising film comprising a soluble deformable polymer material. This material is preferably volatile at the preheating temperatures applied to the sample holder prior to the coating with pyrolytic graphite as this eliminates the necessity for a separate step to remove the film. <IMAGE>

Title: Fencing
Inventor: DARLEY MAURICE
IPC: E04H17/16
Filed: 1985-09-05
Abstract: A security fencing system, of the type used in locations where there is a high-level security risk such as prisons, factories, airports, docks, etc., comprises pairs of complementary uprights (1, 2) which are adapted to be fastened together to face each other one to each side of a fencing screen (6), such as a weldmesh screen. When fastened together the facing surfaces (3) define between them an internal cavity (4) which conceals bolts (14, 19) used to fasten the uprights together and used to fasten the screen (6) to the upright (1) in positive engagement therewith, and which preferably conceals joins between adjacent sections of the screen (6). The exterior surface (5) of the assembled uprights is generally convex and bolts (14) do not protrude so as not to give purchase for a foothold or handhold. The assembled fence may be mounted on top of a stub column (22) mounted in a concrete foundation, in an arrangement which has the advantage that disassembly of sections of the fence is possible without disturbing the foundation to any substantial depth below ground level. <IMAGE>

Patent GB-2173653-A (GB)
Title: Insulation displacement electrical connector
Inventor: JUNIPER ANTHONY JOHN
IPC: H01R4/24
Filed: 1986-04-03
Abstract: The connector comprises a housing (110) having an infeed opening (112) for an electrically-insulated wire. The housing (110) accommodates a fixed contact (114), a pivotally mounted pressure lever (116) acted upon by a compression spring (134) and a pivotally mounted operating member (118) having a cam surface (132) engageable with the pressure lever. The fixed contact (114) and the pressure lever (116) both have co-operating, longitudinally-offset, insulation-penetrating parts (120 and 126). Pivotable movement of the operating member (118) moves the pressure lever (116) against the action of the spring (134) into a position (as shown in the Figure) in which the penetrating parts (120 and 126) cut into the insulation of a wire extending through the infeed opening (112) and grip the wire in a manner which electrically connects the conductor of the wire to the fixed contact (114). The pressure lever (116) has an elongate pivot hole (128) so that it automatically compensates for different wire conductor diameters. <IMAGE>

Title: Bearing and mounting arrangement in a gas turbine engine
Inventor: KEETLEY REGINALD C
IPC: F01D25/16
Filed: 1986-04-28
Abstract: The engine comprises a turbine casing 10, an air intake housing 11, intake support structure 15, an exhaust system 30 and a fluid passage formed through the housing for fluidly connecting the air intake to the exhaust outlet. The stubs 19,21 of an air compressor 18 are rotatably mounted by bearing assemblies 20,22 to support housing 12 while the forward end of the air compressor 18 is open to the air intake 14. Turbine stages 36,38 are positioned within the exhaust passageway 30 and are secured to the rear stub 21 of the compressor 18 by a cone headed turbine bolt 48 so that the bearing assemblies 20, 22 which rotatably mount the compressor stubs 19, 21 to the housing 12 also rotatably mount the turbine stages 36,38 to the housing. The turbine stages 36,38 are located to each other and the compressor by labyrinth sleeves 60,61. The cantilevered mounting of the turbine allows the bearing assemblies 20,22 to be located in a relatively cool zone of the engine thus preventing rapid deterioration of lubricant. <IMAGE>

Title: Valve having an apertured ball shut-off member
Inventor: MITCHELL DENIS RICHARD HENRY
IPC: F16K5/20
Filed: 1986-06-23
Abstract: A shut-off valve has an apertured ball 12 as the valve closure member and valve seats 13 which contact the ball on opposite axial sides around the ends of the aperture in the ball in the open position of the valve. The valve seats 13 are of softer material than the ball, and axially movable members 1, 1a urge the seats into contact with the ball. In order that the seats 13 can be of relatively hard material able to withstand the action of fluids at very high pressure, each seat has a seat backing member 11 of material softer than that of the seat interposed between it and the axially movable member so that the axially movable member applies force via the backing member 11 to the seat. The backing members may be O-rings. <IMAGE>
