Patent FR-2334222-A1 (FR)
Title: Extension cable reel with automatic wind:back system - is actuated by two buttons which also set cable tension and which are held by spiral springs
IPC: B65H75/48
Filed: 1975-12-04
Abstract: A cable reel provides an electrical power extension via five metres of three core, two to ten amp. cable. The reel provides automatic wind-back and a tensioning arrangement using a helical spring as the energy source, which is operated by pressing two buttons. Both buttons are held by spiral springs (13) trapping the cable in its released position by causing lateral movement of two plates. Each plate (11) has a hole (12) through which the cable passes freely when they are aligned and is trapped when they are in their offset rest position. The two-part reel casing is made of plastics and includes a permanent magnet for attachment to steel surfaces.

Title: Compressed air system adjustable pressure regulator - has membrane with control shaft engaging spring loaded valve seat cylinder
IPC: G05D16/06
Filed: 1976-02-09
Abstract: An adjustable pressure regulator included in a compressed air installation comprises a piston moving in a cylinder and across a connecting channel to a flow valve. Pressure of regulation remains unchanged for long periods and is unaffected by dust particles in the air flow. Air from a compressor flows into a pressure regulator connection (3) to a principal chamber. Flow is filtered before passing through channels where a non-return valve allows passage via a connecting socket to a reservoir. Air also flows into a chamber below a membrane (26) to raise a shaft (36) and valve (35) permitting air to enter a cylinder. This action lowers a piston and a plate is raised from its seat, allowing excess air pressure to exhaust the principal chamber via a sleeve. The shaft (36) moves a spring loaded valve cylinder (50) and has its upper surface forming a valve seat, the valve member being a sleeve (46) guided over a membrane plate extension.

Title: Rotation lock for strap hinge - may hold door open with pivoting bolt on axle pin engaging slot in eye
IPC: E05D11/10
Filed: 1976-08-23
Abstract: The rotation-lock for strap-hinges enables a side-hung door or window to be secured in a definitive angular relationship with the closure position.

Title: Electronic fuel injection system for IC engine - has air flow detector responding to pressure upstream of throttle, with signal fed to circuit which also receives tachometer output
IPC: F02D41/18
Filed: 1977-10-21
