Title: Carburettor with auxiliary fuel pump - has bimetal strip closing return opening between float and pump chambers at low temp
Inventor: MENNESSON ANDRE LOUIS
IPC: F02M7/087

Title: Process for switching of load in and out of circuit - involves application of control voltages to thyristor
Inventor: PARMEE RICHARD JOHN
IPC: H02M1/32
Filed: 1975-02-25
Abstract: A thyristor (X1a) or similar semiconductor is connected in series with a load circuit.

Patent FR-2304749-A1 (FR)
IPC: E04H4/08
Filed: 1976-03-19
Abstract: In the case of the roller-blind-type swimming-pool covering, a roller blind (8) is wound onto a winding shaft (1) which can be rotated by a drive. The winding shaft is mounted at a different level from that of the water, with the result that the weight or the buoyancy of the roller blind is not compensated for by lifting forces or the force of gravity. The winding shaft (1) is intentionally dimensioned such that it is bent by the weight and the lifting force. Bending results in the individual roller-blind profile bars being slightly bent when the winding shaft rotates. Consequently, internal friction arises which produces a braking action which prevents the roller blind (8) from rolling out unintentionally, even in the case of interrupted drive connection, and from swelling up during unwinding.

Title: Ski boot manufacturing method - uses prefabricated standard mould shaped on users foot by heat treatment in oven
IPC: B29C61/02
Filed: 1976-04-22
Abstract: The manufacturing method is for ski boots using moulded prefabricated parts which for final shaping are put on the user's foot.
