Title: Safety valve - for wells drawing from different strata
IPC: E21B34/10
Filed: 1973-02-19
Abstract: A safety valve for installation down a borehole comprises a sphere with a passage through it of the largest possible dia assembled in a holder and forming part of the line through which the oil or gas flows. The sphere is turned from a first closed position as it moves downwards to a second open position, by a sleeve in a hydraulic cylinder pressurised from teh surface. When for any reason the control pressure is reduced, a spring aided by the flow from below lifts a sleeve to move back the valve into the closed position.

Title: Vehicle hatch panel postioning and sealing device - has non-reversing rack-and-pinion motor drive for elastic membrane
IPC: B60J7/06
Filed: 1974-09-24
Abstract: The panel covers a hatchway enclosed by a rectangular frame, and comprises an elastic membrane between a fixed component and a housing consisting of two parts pivoting together. The housing is driven by a motor along parallel guides and via pinions meshing with racks and the drive from the motor is non-reversing, so that the panel automatically locks in position when the motor is switched off. The seal is formed by the housing automatically holding the membrane taut, and also by a crankshaft in the housing wih a protrusion which strikes a stop on each rack on reaching the closed position. This causes the shaft to rotate and actuate cams pressing down a flexible component surrounding the hatchway onto the membrane.

Title: Polyurethane foam block of rectangular section - produced by pressing non-porous cover sheet flat onto expanding foam
IPC: B29C44/46
Filed: 1974-12-23
Abstract: An appts. for producing continuous, flat, rectangular-section blocks of polyurethane foam comprises a moving floor or belt and also side walls, onto and between which the material is foamed with the intermediary of a lining sheet to the bottom and walls of the mould. In addn., a device supplies a non-porous covering sheet to constitute a fourth wall of the liner; at the initial foaming position a number of transversely rigid pivoting elements are mounted upon independent frames and extend transversely across the top of the foam to regulate its expansion; these transverse rigid elements, such as rolls or flat sliding plates, ensure that every point of the upper surface of the foam is guided. Adjustment devices enable the pressure exerted by these transverse rolls to be varied, the distance between the pivoting axis and the surface remaining however constant. Where expansion of the foam has ceased, heaters bond the top covering sheet to the foam and, downstream of this, a piercing device comprising needles or spikes forms apertures in the top covering sheet.

Title: Hydropneumatic shock absorbers for road vehicles - have cross linked pipes for oil flow allowing piston movement
IPC: B60G15/12
Filed: 1975-02-25
Abstract: The road wheel is provided with a hydro-pneumatic shock absorber consisting of a piston (9) in a cylinder (18, 20). The upper end of each cylinder is provided with a flexible diaphragm which separates the oil from nitrogen (16) in the space above. When the wheel attached to the rod (14) is forced upwards by a bump in the road, oil is forced through the orifices (6') into the space (18') and compresses the nitrogen (16). At the same time oil flows from the other shock absorber along the pipe (7) into the space (17). This reduces the pressure in the space (1), allowing the wheel attached to the rod (12) to rise and so prevents the vehicle from pitching.

Title: Support for end mill during profile milling - has top held by rotating spindle and bottom by bracket with support arm trailing cutter
Inventor: FORAY ROGER
IPC: B23C3/26
Filed: 1975-04-22
Abstract: The end mill support comprises a cage fitting onto the rotating machine spindle (2) by ball races (4). The cutter (3) is held by a plate on the spindle nose. A support arm (6) having a kidney shaped cross section is attached to the cage and has a bracket (7) at the bottom. A bearing (8) in this bracket, in line with that on the upper plate, holds the other end of the cutter to prevent bending. The cage is mounted free on the spindle nose. The friction of the ball races and the seal ring (15) automatically causes the support arm to trail behind the cutter.

Title: Box file with hooks on spine panels - has filing rings hooked to grip sheets or unhooked for filing sheets
IPC: B42F13/16
Filed: 1975-06-26
Abstract: A box file has its covers and back consisting of a central panel forming the spire, with a cover panel, and each side, and with a further narrow auxiliary panel between each cover and the spine panel. The rings which carry the documents are D shaped and are retained permanently on one of the auxiliary panels. Securing hooks for the rings are mounted on the other auxiliary panel and on the spine panel. By disengaging the rings completely from the hooks, the whole can be opened out flat for ease of filing. In this position, the joints of the rings are uppermost. The rings can alternately engage the hooks on the spine, so that the joints are sideways. Finally the rings can engage the hooks on the spine and also on the auxiliary panel so that the three panels form a U shape gripping the edges of the filed documents.

Title: Test bench for liq. meters - compares theoretical flow rate with flow rate measured by meters
IPC: G01F25/00
Filed: 1975-08-04

Title: Delayed action switch with moving contacts on sprung T piece - has return of T delayed by friction element acting on stem
Inventor: SULTAN JEAN-CLAUDE
IPC: H01H13/24
Filed: 1975-10-03
Abstract: The delayed action switch consists of an operating post moving axially to move a T-shaped contact axially away from fixed contacts. The contact buttons are at the ends of the top surface of the crosspiece of the T. The stem of the T is loaded by a return spring. To delay the return of the T-piece, a friction element is located in the base of the switch housing and acts on the end of the stem of the T as the latter passes through it. The friction is sufficient to delay the return of the T by 0.2 to 1 second.

Title: Clamp bolt for assembling structural sections - uses pointed grub screw bearing on ball to draw bolt against spring
IPC: F16B7/04
Filed: 1976-01-06
Abstract: Aluminium structural sections may be assembled by means of this sliding bolt, which essentially clamps one section (E1) to the other (E2) as a grub screw (23) is tightened. The bolt (15) slides in a housing (10) fixed to, or part of one section and is hollowed, so that it may contain two balls (19, 20). The balls are retained between the end flange (18) of the bolt and a similar flange (13) of a U section element (22) also in the housing. The other flange (14) of this element extends beyond the end flange of the bolt, so that a spring (21) may be inserted between the two. This spring tends to eject the bolt from the housing to a position limited by the ball diameter. A grub screw (23) with a pointed end screw through the web of the U element and penetrates between the balls, at the same time locating the U element by passing through the housing wall. As the screw is tightened, it forces the balls apart and draws the bolt into the housing.
