Patent FR-2302168-A1 (FR)
Title: Metal sheet edge flanging machine - has tool mounted on carriage driven round profiled sidewall of support
IPC: B21J5/02
Filed: 1975-02-07
Abstract: The machine tool, for flanging or cutting the edge of a metal sheet, uses a support with a top which does not extend to the edge of the sheet, and a tool which is lowered for flanging or cutting. The tool is mounted on a carriage which is driven round the side wall of the support. The side wall possesses a contour similar to that required on the workpiece. Different types of tool may be mounted on the carriage. The support pref. consists of a box to which suction is applied for holding the sheet metal workpiece by vacuum during the flanging or cutting operation which uses a forming roll or milling cutter. A sheet of metal with any desired contour, e.g. an oval shape, can thus be provided with a flange.

Title: Friction spring for oscillation damping - has series of conical plates with connections at inner and outer edges
Inventor: STIEFEL CHRISTIAN
IPC: F16F1/32
Filed: 1975-07-21
Abstract: The spring consists of conical shaped circular discs which are situated on top of one another to accept axial loading. The conical surfaces of adjacent conical discs are at an angle to one another. The design is particularly for railway rolling stock and is a simple and cheap way of achieving the required friction and hence the specified damping. The conical discs (1, 2) have an interlocking connection at their outer (1a, 2a) and inner (1b, 2b) edges. This connection is, in principle, a beading with circular cross section (1c, 2c) fitting in a semi circular recess (2d, 1d). An alternative design has slotted or unslotted rings on the inner and outer edges of the conical plates.
Patent FR-2319391-A1 (FR)
Title: Automatically releasing safety belt lock - has spring lazy tongs mechanism freeing jaws to release key after severe shock
IPC: B60R22/32
Filed: 1975-07-30
Abstract: The lock releases a safety belt subsequent to a violent shock, and has a latch which, under the effect of the shock compresses the springs, controlling the release of the lock and mounted between latch and housing, and extends a lazy tongs mechanism. The rigid ends of the tongs engage between two jaws after depressing their spring heads. Immediately after the shock, the force acting on the latch relaxes, and it is thrust back by the springs into the initial position, and the tong ends thrust the spring jaw heads outwards, causing the jaws to rotate and freeing the locking key. As the tong ends come free of the jaws, the latter are returned to the starting position by leaf springs mounted between them and the housing.

Abstract: The electric traction system has a DC supply line and a thyristor controlled current feed to the asynchronous motor. The two lines to the system are each protected by control circuits, with one of the control circuits having thyristor elements and the other a simple switching protective element. This is closed when the motor is driven. If the brakes are applied the protective switch is opened to allow regenerative braking to take place, with the output from the motor switched to the correct polarity to feed back into the supply line.
