Patent FR-2588092-A1 (FR)
Title: Method for producing an "adhered" polariser and polariser produced thereby
Inventor: POCHARD MARC HENRI
IPC: G02B5/30
Filed: 1985-05-21
Abstract: This method for producing a polariser including two solid transparent blocks 1 and 2 in contact, by means of plane faces, with a liquid transparent thin film 3 consists in assembling these blocks by means of a flange 4 which preserves a certain elasticity in order to reduce the effects of the mechanical stresses resulting from thermal variations. For this purpose, the edges 5 and 6 of the said plane faces are chamfered over 0.5 mm. The chamfered surfaces are covered with a non-stick (antiadhesive) substance 9-10 for the epoxy joint formed by the remote-manipulation device in the form of a flange 4 in the liquid. During manipulation, intermediate operations are performed for attaching the flange and for removing, by outgassing, the bubbles formed in the liquid. The block 1 of the polariser consists of a birefringent material. The liquid of the thin film 3 and the material of the block 2 have the same refractive index which is equal to the smallest index of the birefringent body. Application: light polarisers.

Patent FR-2593687-A1 (FR)
Title: Heating seat
IPC: A47C7/74
Filed: 1986-02-02
Abstract: The invention relates to seats of various types, having a self-contained built-in heat source. The model represented is an armchair having an enveloping shape, where the heat is produced by means of chemical resistors R, and carried by means of a natural hot air draught. A similar model comprises an accelerating fan. A variant, without air circulation, consists in incorporating the resistors into the inner padding of the armchair. The principle of the heating seat can be applied in sanitary equipment: the icy contact between the bidet and the skin is avoided by heating the periphery of the bowl by means of the hot water used.

Title: Compact and retractible head-up collimated-display device
Inventor: BOYER CLAUDE
IPC: G02B27/01
Filed: 1986-02-14
Abstract: The device enables the instantaneous elevation field of view to be increased using a mounting having two parallel mirrors and producing a minimum masking effect. The two mirrors 4, 5 are placed inside the casing 1 in order to produce the increase in the elevation pupil and a single mirror 6, placed outside the casing, constitutes the optical combining system. A mechanism 8 for retracting the combining mirror, which is positioned 6 above the casing beyond the field of view of the external background, is also added with the purpose of reducing the masking effect during the periods when the collimator is not being used. The invention applies to aeronautics in order to form a head-up sight, preferably for using in a low position.

Patent WO-8905383-A1 (WO)
Inventor: VINOCOUR ROBERT
IPC: E04B2/82
Filed: 1988-11-08
Abstract: The partition described is formed by assembling vertical panels (P1) along their vertical edges. Each panel is formed by assembling two half panels (P'1, P''1) into a single panel by means of a fastening device comprising two profiled framing elements (E) in the form of angles which cover the side edges of the panel and by clamping means (115) capable of exerting a clamping force on the two elements (E) which brings them closer together. The invention makes it possible to incorporate circuitry in the partition without affecting the mobility of the latter.
