Title: Metering device for fine powder - has endless discharge chain receiving powder fed by blades
IPC: G01F13/00
Filed: 1974-04-17
Abstract: The dosage of small quantities of fine powder such as silicon is achieved without use of vibration or fluidisation.

Title: Wind driven generator with twin vertical cylindrical rotors - having surfaces deformed by wind pressure to form blades
IPC: F03D3/02
Filed: 1974-12-16
Abstract: The generator is driven by two cylindrical rotors (6, and 7) mounted on vertical shafts (8 and 9) on a platform (1). The wind is directed by a venturi to blow into the small gap of about 10 cm between the rotors. The venturi is mounted on bogies (24-28) which run on a circular track (29, 30) so that the venturi together with the platform (1) can be rotated to face the wind. The rotors are made of thin flexible rubber sheet and inflated with low pressure air. As the wind blows between the rotors the pressure of the air causes local deformation of the rotors producing a temporary blade which causes the rotors to rotate.
Patent FR-2310143-A1 (FR)
Title: Toy using effects of static electricity - has light paper or plastic figures attracted or repelled by rubbing plastic container
IPC: A63H29/00
Filed: 1975-05-06
Abstract: The toy comprises a transparent plastic container which can be of any suitable shape. Inside this is placed a figure made of light paper or plastic sheet. This figure, animal or human, is either suspended by threads from the top of the container or mounted on a support fixed directly to the floor.

Title: IC engine oil press control/relief valves - design combining both and permitting smaller coolers and filters
IPC: F01M5/00
Filed: 1975-11-28
Abstract: The overpress. relief valve (12), operated by the press. at pump discharge (4) acting against a spring (15), also forms the seal for ports (16) in a sleeve valve (13) actuated by system pressure at entry to the engine, transmitted through a pipe (8) and acting on a piston (17) opposed by another spring (18); both valves discharge to a common return line (9). This arrangement, while maintaining the normal system characteristics, permits one valve assembly, substantially, to be used to do the work of two, and reduces the oil flow through the cooler and filter by short-circuiting oil surplus to the engine's actual requirements.

Patent FR-2354907-A1 (FR)
Title: Control valve for servo brakes - with stepped piston to enclose fluid volume for manual braking with servo failure
IPC: B60T13/14
Filed: 1976-06-15
Abstract: The servo control valve has a stepped piston (2) operated by the manual input shaft (17) and controlling the flow of fluid from the high pressure inlet (15) to the high pressure outlet (14), as well as the low pressure outlet (5) return to the sump. The piston encloses a trapped volume of fluid when displaced so that a manual braking effort can be provided on servo failure. When the stepped piston is displaced it seals the connections between the servo inlet and the outlet, if the servo pressure drops, while at the same time closing off the low pressure venting duct. The valve provides a fine degree of control over the servo force with the failsafe interlock of manual control.
