[origin: US4497011A] PCT No. PCT/DE82/00096 Sec. 371 Date Jan. 13, 1983 Sec. 102(e) Date Jan. 13, 1983 PCT Filed May 5, 1982 PCT Pub. No. WO82/04160 PCT Pub. Date Nov. 25, 1982.A switching unit (1) for changing the polarity or the magnetic field-strength of ferromagnetic bodies, for example of permanent-magnet clamping devices, possesses a series-arrangement comprising at least one coil (3) which is suitable for receiving ferromagnetic bodies (6), a controllable electronic switch, and an energy-storage system (10). The object is to provide a compact switching unit which switches reliably and which possesses a simple electrical circuit. This object is achieved by means of a switching unit which comprises an electronic switch, in the form of a flashlamp (2).
Abstract (fr)
Un appareil de commutation (1) pour changer la polarite ou l'intensite du champ magnetique de corps ferromagnetiques, p.ex. celui de tendeurs a aimant permanent, presente un arrangement en serie. Cet arrangement contient au moins un enroulement (3) apte a recevoir des corps ferromagnetiques (6), un commutateur electronique commandable ainsi qu'un dispositif d'accumulation d'energie (10). Afin de creer un appareil de commutation de petite dimension, a circuit electrique simple et a commutation fiable, on choisit comme commutateur electronique une lampe eclair (2).
