Title: Stop control for textile bobbin - where transfer tail is used to trigger stop during unwinding
Inventor: LAURENT MAURICE
IPC: B65H63/08
Filed: 1980-05-06
Abstract: Winding bobbin supports a main yarn winding, and a winding transfer tail and is mounted on a package support having a metal lever which occupies two positions. The first position allows unwinding to proceed, and this position is held by the first winding loop of the transfer tail. On the unwinding of this first spiral, the lever rocks to a second position, which completes (or breaks) an electronic circuit to stop unwinding before the transfer tail is run off. The unwinding process is arrested before complete exhaustion of the wound yarn from the package, by arranging the stop as the transfer tail begins to unwind.

Title: Magnetic mounting for electric starter motor - uses section of motor casing forced into dove-tail shaped hole in outer surface of magnet
Inventor: JOURNET ANDRE
IPC: H02K1/14
Filed: 1980-08-13
Abstract: The process for attaching magnetic poles into a motor casing is partic. suitable for constructing starter motors. The pole pieces (3) on which a winding (2) is formed has a concave surface facing the rotor of the motor, and a smaller convex surface fitting against the casing (1) of the motor. The convex surface has a dovetail shaped hole cut in it, the hole (4a) becoming wider as it cuts deeper into the pole piece. With the pole piece in situ inside the casing, a small part of the casing material is pushed through so that it touches the bottom of the dovetail hole. The projection is then further enlarged using a suitable tool so that it extends across the full width of the base of the hole, securing the pole piece to the casing. The technique does not require the accurate alignment which is necessary for rivetting or screw fitting.

Inventor: NAUER PAUL
IPC: G05D23/12
Filed: 1980-09-17
Abstract: The radiator control head (1) is provided with a vapour pressure/temperature sensor (7). A heat-conduction plate (14) set into the end of a control knob (3) of the control head (1) is in permanent contact with a surface (13) of the temperature sensor (7). This achieves better coupling between the temperature sensor (7) and the room temperature and, thus, a reduced influence of the radiator temperature on the temperature sensor (7).

Patent FR-2475099-A1 (FR)
Inventor: SCHWORER ARTUR
IPC: E04G17/04
Filed: 1981-02-05
Abstract: When lowering the floor shuttering, the supports are left in their support position. The shuttering has principal girders which are supported on the lowering head and bear the shuttering panels for the floor. To the side of the principal girders (3), there are provided, such that they can be displaced in stages, compensating girders (5) which have a bearing means for the shuttering panels (14). The amount by which the upper surface (56) of the compensating girder (5) is lower than the upper surface of the principal girder (3) corresponds to the distance between the shuttering surface and that surface of the shuttering panel resting on the upper surface of the compensating girder. A length compensation can thus be carried out in a simple manner.
