Patent GB-2108187-A (GB)
Title: Concrete forming apparatus
Inventor: MYGIND HANS HOLGER SYDNEY
IPC: E04G11/28
Filed: 1981-10-19
Abstract: Apparatus for forming hollow upright concrete structures by the jump-forming technique is disclosed which is particularly suited to structures where significant changes in circumference are required, as for example, in hyperbolic cooling towers. The apparatus comprises a plurality of units each consisting of a line of inner shutter panels (1A) and a line of outer shutter panels (1B), individual panels having common dimensions and being releasably incorporated in their line such that the overall length of the line can be changed (to suit changes in structure circumference) by adding or removing panels. Resultant changes in radius are simply accommodated by adjusting a tie assembly (6) interconnecting bracing carried by each panel. The lines of panels are carried by support post assemblies (9) relative to which they are pivotable and the lines of panels and their support post assemblies are securable to the structure being formed by brackets. During concrete formation the brackets are in lowered positions relative to the post assemblies (9). Lifting of the units for forming further concrete is effected by releasing the brackets but not the panels from the structure, raising the brackets and re-securing them to the structure at raised positions relative to the post assemblies, releasing the panels but not the brackets from the structure, raising the post assemblies and hence the panels relative to the brackets, and re-securing the panels to the structure with the brackets again at their lowered positions relative to the post assemblies. <IMAGE>

Title: Sign box
Inventor: RADIN GERALD KENT
IPC: G09F13/04
Filed: 1981-10-28
Abstract: The bottom edge of the front face of the top rail of the, or a, panel-carrying frame of a sign box is formed with an overhang 23 to encourage rain or condensation striking the front face to drip off the overhang, rather than running onto and down the panel. A relatively shallow channel (26) may run along the top face 27 of the top rail to lead water off the top face of the panel-carrying frame. Where the box pivots open about the top back edge of the panel- carrying frame, the configuration of the mating fit between the panel-carrying frame and the main box frame is preferably such that any water attempting to find its way into the box through the pivot region is confronted with, in succession, an overhang on the turned-up pivoting edge flange 32 of the back face of the panel-carrying frame, and a resiliently deformable seal 36 compressed between the panel-carrying frame and the main box frame. A double-faced sign box and single-faced box are described and illustrated. <IMAGE>

Title: Mine for combating land vehicles
Inventor: PETTERS WILLI J
IPC: F42C11/00
Filed: 1981-11-06
Abstract: A mine for combating land vehicles, comprising a hollow charge and a space charge for the removal, prior to ignition of the hollow charge, of a camouflage layer usually covering the mine, avoids undesired ignition of the space charge if a track or wheel of the vehicle applies pressure above the mine. Sensor S1 determining pressure4ree passage is activated at time t0 and feeds a signal to gate G1; in the absence of any further signal to G1 the detonators Z1, Z2 for the space and hollow charges are detonated after time intervals  DELTA t1,  DELTA t2 ( DELTA t2 >  DELTA t1). However if after time interval DELTA t3, ( DELTA t3 <  DELTA t1), sensor S2 determines pressure loading from a track or wheel, G1 and Z1 are blocked and Z2 is detonated after time interval  DELTA t2. <IMAGE>

Title: Improvements in or relating to vehicles
Inventor: COMER ARNOLD HENRY
IPC: B60P1/16
Filed: 1981-11-27
Abstract: A vehicle body is mounted on a turntable located on a chassis sub-frame enabling the body to be rotated through 90 DEG  about a vertical axis to both sides of the chassis. Rotation of the turntable is achieved through the action of one or two pneumatic piston and cylinder arrangements acting against the upper ring of the turntable. The body may be a van so that rotation provides easier access to its loading doors. Alternatively the body may be capable of end tipping so that rotation allows for discharge at the sides of the vehicle.
Patent GB-2091001-A (GB)
Title: Pressure unloading valve assembly
IPC: G05D23/185
Filed: 1981-12-10
Abstract: A pressure unloading valve assembly (2) includes a spool valve (24) and temperature-responsive valve (8) for selectively unloading hydraulic fluid to drain. (Via 66 and 74). In series with the temperature- responsive valve (8) is a threshold valve (100) comprising a body containing an axially slidable valve member biased to close the valve by a spring. An enlarged pressure- responsive area on the member, acted on only after initial opening of the valve (100), and a flow restriction in the passage through the valve (100) give it a hysteresis characteristic. When the pressure in an inlet passage (59) reaches a threshold value the threshold valve (100) is opened, and it remains open when the pressure in the inlet passage (59) falls below the threshold value. The flow restriction restricts the action of the unloading valve (24) so that even when the temperature-responsive valve (8) and threshold valve (100) are open, the pressure in the inlet passage (59) is slightly above drain pressure, to drive components in an associated hydraulic circuit (not shown) at idling speed. <IMAGE>
Patent GB-2125091-A (GB)
Title: Lock especially for vehicle boots
Inventor: WHITE WILLIAM
IPC: E05B35/04
Filed: 1981-01-23
Abstract: Lever 15 located in the saloon compartment of a vehicle may when unlocked, be moved to release the boot etc. lid. The movement is conveyed via Bowden cable 9 to slider 37, which releases one of the flats on the octagon 40 attached to a spring- urged drum on which wire 54 is wound. In this position the boot lid 60 may be raised; when it is lowered the tension of spring 57 winds up the cable slack.   The locking mechanism 1 only allows lever 15 to move when bolt 7 may slide transversely to blocking elements 14 and internal walls 13. This may happen when a pronged key has been inserted over stops 6 to push each blocking element 14 by the amount required to align its transverse slot 19 with slots 18 in the walls 13. This allows lugs 3 on bolt 7 clear paths so that the bolt 7 may move and allow the linked lever 17 to pivot. <IMAGE>

Title: Shot blasting equipment
IPC: B24C5/04
Filed: 1982-03-19
Abstract: In shot blasting equipment where blasting medium is directed against a surface from a nozzle, ricocheting grit is a major problem demanding extensive protection to the operative and to any equipment in the vicinity of the area to be cleaned. Dust is also a problem caused by disintegration of the grit as it strikes the surface. Such problems are eliminated to a substantial degree, by having a shield 1 secured to a nozzle 7 of the equipment said shield having divergent walls 2 surrounding the nozzle outlet with an operative edge 4 adapted to be held in close proximity to the surface to be cleaned. Thus any dust and any ricocheting grit is held in the enclosed space between the said surface and the shield and is allowed to fall through a gap between the lower end of the shield and the surface which may be created by especially formulating the edge of the shield. <IMAGE>

Patent GB-2106992-A (GB)
Title: Isothermal positive displacement machinery
Inventor: COLGATE STIRLING A
IPC: F02G1/053
Filed: 1982-09-13
Abstract: In such machinery, e.g. a Stirling cycle heat pump, improved heat flow, and thereby thermal efficiency, is achieved by providing a large chamber wall area to chamber volume ratio through the use of bellows-like walls for the compression and expansion chambers 1 and 2. The gas chambers have movable end walls 4 and 5 which are reciprocated by connecting rods driven by cranks 6 and 7 on a motor-driven shaft 8. The machinery may instead consist of a positive displacement engine or a compressor. Significant gains in thermal efficiency, up to a factor of 2, are attainable because the largest inefficiency in all isothermal machinery is imperfect control of heat flow. A regenerator for extracting heat from and returning it to the gas in the chambers is preferably provided between the chambers 1 and 2. The regenerator minimizes cycle losses due to gas transfer friction, gas thermal conduction, dead volume, regenerator heat mass, regenerator heat mass thermal skin depth, and regenerator mass thermal conductivity in the gas flow direction. <IMAGE>
