Title: Floats for walking on water - are connected in pairs by central band, and may be joined by rings and cord to form e.g. seat or mattress
IPC: B63B35/81
Filed: 1980-10-03

The appliance consists of four lightweight floats which may or may not be inflatable, and are joined in pairs by a central, flexible or rigid band. Each pair of two floats has a small cord fixed to a ring at one end, on the ouside float. The floats can be tightened together by the cord and rings to form an inflatable structure.
Patent FR-2469499-A1 (FR)
IPC: E01H10/00
Filed: 1980-11-13
Abstract: In a casing (1) having an inlet (3) and an outlet (4), there is rotatably arranged a rotor (20) which has rows (25), which are arranged at intervals, of carriers made of plastic bristles. The axes of the inlet (3) and the outlet (4) are only inclined with respect to one another to the extent that at least two rows of bristles rest against the inside peripheral wall (2) and in so doing ensure that the scattering material is sealed off effectively. The shaft (22) of the rotor (20) is coupled by means of a coupling (32) which is torsionally elastic in the circumferential direction to the drive shaft (31) of an electric motor (30) in order to keep the starting load of the motor (30) small. The electric motor (30) is fully encapsulated and it is surrounded by a casing (33) which is connected to the casing (1). A collar (34) provides hermetic sealing at the connection point. The relatively small deflection of the scattering material between the inlet (3) and the outlet (4) means that friction losses in the rotor (20) are relatively small.

Title: Car anti-theft wheel-nut - has cylindrical head containing notches over which co-operating hexagonal key locates
Inventor: PAROLI GIOVANNI
IPC: F16B23/00
Filed: 1980-11-13
Abstract: The anti-theft wheel-nut (10) for cars has a cylindrical head (13), the external surface of which carries notches (14) in a predetermined angular position. A cooperating externally hexagonal key contains a cylindrical cavity, the internal surface of which carries projections complementary to the notches (14) in the nut. When the key is located over the head (13) of the nut, the projections on the key engage into the notches allowing the wheel-nut to be turned. The angular position of the notches and the projections varies so that each key only fits the nut to which it is associated.

Patent FR-2474749-A1 (FR)
Title: Solenoid winding for electrically operated valves - has insulating wing element extending to extremities of coil winding and situated at end of wire entry passage
Inventor: NOVELLONE ALESSANDRO
IPC: H01F/
Filed: 1981-01-16
Abstract: The winding is provided with a passage (22) for the supply wires to the winding. At the end (26) of the passage a fin of insulating material (28) connects to the winding. The former (12) for the coil rests between two arms of a magnetic material cup (10) with one arm holding a sleeve which forms the passage way for the wire from the wire entry to the end of the coil former. Locating studs in the sleeve mate with the cup and hold the coil former in place. Radial notches in the cap of the insulating sleeve serve to hold the supply wires. This form of construction obviates the need for moulded encapsulation. The device avoids splitting and underised displacements of the ends of the coil, even when the ends are made of flat, thin wire and are not reinforced.
Patent FR-2500076-A1 (FR)
Title: Vertical axis multi-blade wind turbine - uses opposing blades actuated by cross-coupled pneumatic cylinders to retract returning blade while opening facing blade
IPC: F03D3/06
Filed: 1981-02-17
Abstract: The arrangement uses cross linked pneumatic cylinders to open out the blade facing the wind flow and simultaneously retract the blade returning against the wind flow. In this way the net torque on the turbine is maximised. The turbine has an even number of diametrically opposite blades, mounted on a polygonal frame attached to the central hub. One pneumatic cylinder for each blade is pivoted from the central hub at one end, and is pivoted from a blade at the other end. Diametrically opposite cylinders have their air lines connected one to the other, so while one retracts, as the blade returns against thewind, it forces the opposite one outwards to face the wind. The mechanical energy obtained can be used for electricity generation.

Patent FR-2524760-A1 (FR)
Inventor: BINET MAX
IPC: H01L23/473
Filed: 1982-03-30
Abstract: The novel mounting simultaneously provides for the mounting, connection and vigorous cooling of a semiconductor component which has to withstand a high heat dissipation. The semiconductor component (30) is situated between two bodies (17, 17') of two cooling devices (20, 20') which are pressed against the component. The electrodes (1, 4) of the component are electrically connected by leads (19) which are formed at the heads (18) of the cooling devices (20'). The gate electrode (3) is electrically connected by an elastic attachment which is clamped in the gate hole (8) formed in the body (17) of the cooling device (20'). Cohesion is achieved by clamping the component (30) between the two bodies of the cooling devices (17, 17'). Cooling takes place as a result of a cooling fluid flowing through a labyrinth (11, 12, 13, 14, 15, 16) hollowed out in the interior of the body of the cooling device.

Title: Aluminium wire prodn. from continuously cast strand - using high cooling rate to modify sec. phases (HU 30.8.82)
Inventor: KERTESZ LASZLO
IPC: B22D11/00
Filed: 1982-04-09
Abstract: In the prodn. of aluminium wire by melting aluminium contg. max. 0.7% impurities, continuously casting the melt, naturally cooling the cast strand at about 100 K/sec. and then working to wire, the cast strand is cooled at a rate of at least 2.5 times the natural cooling rate (pref. at at least 1000 K/sec.), using a liq. or solid coolant, at the end of the first arrest during cooling. The compsn. of the sec. solid phase (eutectic of impurities with aluminium) is offset in the direction of the metastable eutectic (the supersaturated soln.) to avoid redn. in mechanical properties, without affecting the desired crystalline structure of the aluminium matrix which solidifies first. The resulting wire has unchanged electrical properties but has increased bending fatigue resistance, after heat treatment, similar to that of copper wire.
Patent FR-2508408-A1 (FR)
Inventor: KELLER JOSEF
IPC: F16H7/08
Filed: 1982-06-22
Abstract: The invention relates to a dérailleur, in particular for bicycles, which is set up for braking by backwards pedalling. For this purpose, in the region of the movable swivel head there is provided a wheel which can be set in rotation by the chain, on backwards pedalling locks the chain-tensioning device against rotation via a friction spring and thus prevents the upper strand of the chain from sagging too much and prevents the backwards pedalling movement for initiating the braking process resulting in too great a pivoting angle at the pedal spindle.
