Patent FR-2479640-A1 (FR)
Inventor: ERLAM DAVID PAUL
IPC: A47B47/03
Filed: 1981-03-27
Abstract: The simply constructed and cost-effective frame of skeletal construction has vertical limbs (1) which are arranged at the corners of the frame and are connected to one another at the top and at the bottom of the frame by flexible endless metal strips (2 and 6). These endless strips are passed around the limbs and are tensioned by means of clamping devices (4 and 8) which are arranged between the limbs (1). Each clamping device (4, 8) has a central hub (11), elongated struts (12) which extend outward from the hub (11) and in each case engage with one limb (1) as well as an adjusting device having a screw (19) by means of which the struts (12) are pressed outwards in order to tension the endless strips (2, 6) such that the frame remains stiff. The bottom, top and other sides of the frame are clad with sheet metal and a door which can pivot.

Title: Machining and reshaping of laminated strip for spectacle side arms - to provide the supported end with the same surface finish as the body of the side-arm
Inventor: MINART FRANCOIS
IPC: B29D12/02
Filed: 1981-04-01
Abstract: Laminated sheet strip for use as spectacle frame side arms is modified at one end by longitudinal machining using a bell-section radial miller to remove part of the core material and leave a radiused end. The residual tip layer, comprising the original surface backed by a reduced depth of core material, is then reformed to follow the radiused surface. Improves the appearance of the side arms by allowing the surface finish to extend without a break over the end of the side adjacent to the frame. The reformed tip is fixed to the radiused end of the cut core by using an adhesive or, for thermoplastic materials, by solvent or pref. ultrasonic or friction welding. Any surplus tip may be trimmed off flush with the inner surface of the sidearm. While the machined strip is still clamped, ancillary fittings such as hinge sockets, may also be fitted.

Title: Insulating protection ring for overhead power cable - uses rings fitted onto outside of cable and having protrusions for mutual engagement
Inventor: MARTIN MAURICE ANDRE
IPC: H02G7/16
Filed: 1981-11-19
Abstract: The ring (1) which is to be attached to an overhead electric cable comprises an open cylinder (2) whose internal dia. exceeds the dia. of the cable. Inside this ring there is a half cylindrical portion (4) whose external dia. matches the internal dia. of the ring, and whose internal dia. fits the cable. A slot (5) extending along the two parts allows a plastics component to be bent to make it fit over the cable. Two such elements may be snap-fitted together to form a cylinder surrounding the cable. By putting these cylinders at intervals along a cable, the risk of damage by snow and ice is reduced. Each ring element is formed from one piece.
Patent FR-2496321-A1 (FR)
Inventor: CARLSON WILLIAM RALPH
IPC: G21C7/32
Filed: 1981-12-15
Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the watermoderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical- thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Title: Vehicle antitheft device - uses parallel electronic network including automatic alarm surveillance initiation
Inventor: LEROY MICHEL ANDRE
IPC: G08B13/08
Filed: 1982-03-15
Abstract: The device uses a number of surveillance contacts associated with different parts of the protected vehicle and each coupled to an alarm signalling device via an electronic control with a number of parallel circuits. Each of the parallel circuits has a multivibrator stage and is associated an input delay stage and an alarm delay stage, the former incorporating a logic gate for only allowing the alarm release signal to be transferred when the device is in the surveillance state.

Abstract: A clutch disengaging apparatus wherein an annular cylinder defines an annular cylinder chamber receiving a reciprocable annular piston with an annular outer clearance surrounding the outer skirt of the piston and an annular inner clearance surrounding the inner skirt of the piston. A membrane overlies the bottom wall of the piston and its marginal portions are clamped between the sections of the cylinder so that the membrane forms an outer corrugation in the outer clearance and an inner corrugation in the inner clearance. A throw-out bearing is radially movably mounted in the piston and is biased against the prongs of the diaphragm spring in a clutch by a coil spring which is surrounded by an inner wall of the cylinder, which surrounds an outer wall of the cylinder, or which is installed in the cylinder chamber between the bottom walls of the piston and the cylinder. The piston is guided against radial movement with reference to the cylinder by a tubular guide member which is connected to or forms an integral part of the inner wall of the cylinder and is tracked by one or more followers of the piston.

Title: Device forming a revolving joint for a cryogenic fluid, such as liquefied natural gas
Inventor: TUSON SAMUEL
IPC: F16L39/04
Filed: 1983-01-13
Abstract: The invention relates to a device forming a revolving joint for a cryogenic fluid. This device comprises a fixed part 1 and a rotary part 2, each part comprising at least one corresponding duct 6 suitable for the circulation of the cryogenic fluid through the joint. This device is characterised in that it further comprises thermal insulation means 8, sealed to the fluid, for at least the walls of the joint in contact with the cryogenic fluid, constituting vital parts of the joint, such as, in particular, the parts situated in the region of the plane of the joint between the fixed part 1 and the rotary part 2, relative to the surrounding medium 9, in order to avoid freezing of the joint at least in the region of its vital parts.
