Patent FR-2550455-A1 (FR)
Title: Hook for windsurfing harness
IPC: B63B35/79
Filed: 1983-08-12
Abstract: The invention relates to a controlled-opening hook for a windsurfing harness so that the user can release himself easily and instantly at any moment, whatever the tension on the harness and even in the absence of any tension. It comprises a strap-carrying plate 14 attached to the harness and fixed to this plate is a hook 12 which holds a cord 17 connected to the boom. The hook 12 is held in place by the piston 7 which is blocked by the catch 3. Action on the detent 1 releases the mechanism which throws the hook 12 forward. Returning the hook 12 to its position resets the whole mechanism. The invention may be applied to the harness of a sailboard or dinghy, and its detent system to any other use in which it is necessary to free oneself or some object instantly from a tension, whatever tension this may be: towrope, safety belt, crossbow, etc.

Patent FR-2553871-A1 (FR)
Title: Method of heating an object by solar radiation and solar sensors for implementing the method
IPC: F24S20/20
Filed: 1983-10-20
Abstract: The method involves the capture of solar energy. A converging optical system 1 forms a luminous spot 5 at the surface of the object 2 to be heated. The surface has a thermally insulating reflecting coating 3 which disappears at the position of the spot 5, producing a window 4 through which energy exchange can take place. The window, being coincident with the spot 5, moves with the spot as the sun moves across the sky. The reflecting coating 3 may consist of a metallic layer which is vaporised at the position of the spot 5 and is then deposited once more on the object 2, reconstituting the reflecting coating where it was before being displaced. The method makes it possible to dispense with a device for tracking the sun.

Patent FR-2577513-A1 (FR)
Title: Directional invertor and force-reducing gear for oars
IPC: B63H16/10
Filed: 1985-02-18
Abstract: This apparatus has the purpose of propelling a boat in the direction in which the rower is facing, and not backwards, like the current principle. Two of these appliances per boat are required. By pulling on the shaft 17 of the oar, the rower (oarsman) pivots a toothed sector 10 which meshes on another sector 2, and the latter drives the blade 5 of the oar. The boat thus progresses forwards. The apparatus 1 is mounted on an articulation 13 allowing the blade 5 to be taken out of the water. Furthermore, the diameter of the sector 10 is less than the sector 2, which has the advantage of reducing the force provided by the rower. By reversing (by virtue of the identical diameters of the shafts 3) the sectors 10 and 2, the speed is increased. The system is protected against corrosion and is provided with antifriction rings 7 and 14. The elements 6 and 11 protect the sectors. This invention is intended for any person using a boat with two or more oars, either for fishing, leisure or competition.
