Patent FR-2569299-A1 (FR)
Title: Polarised electromagnet having a symmetrical arrangement
Inventor: GUERY JEAN-PIERRE
IPC: H01F7/08
Filed: 1984-08-20
Abstract: The invention relates to a symmetrical monostable polarised electromagnet in which a stationary permanent magnetic structure 15 and a moving magnetisable structure 2 passing through the coil 5 are of such a size that the departure from the rest position R of the moving structure, for a given number of ampere turns, can be produced with certainty by virtue of an air gap adjustment 33 whereas the return from the working position T is ensured by the presence of a second air gap 35 and by the action of a return spring 36. The invention allows in particular the reduction of the remanence holding effects appearing in the working position as well as the power necessary for supplying the coil in order to carry out its change of state when the coil is at rest.

Title: Loader for agricultural use
Inventor: MENGELE DIETER PAUL
IPC: A01D90/04
Filed: 1984-09-21
Abstract: The loader has a collection and transportation system in which the harvested product picked up from the ground by a collection drum is brought into a transport channel and is transported into a receiving vehicle. Above a scraper wall, on a toothed shaft, a row of teeth is supported. These are in the shape of rakes or combs which overlap the upper scraper wall. The teeth are able to pivot across the transport channel by the use of a hand lever. This lever can be immobilised in the rest position of the teeth on the vehicle superstructure. A spring device may be used to bring the teeth into a first position with their overlapping parts inside the passage slots in the scraper wall.
