Abstract: In order to render possible a compact means for power distribution and fuse protection on the basis of a printed circuit board, the apparatus has a multiple fuse arrangement which comprises a plurality of fuses and is connected to a plurality of output contacts. Furthermore, a printed circuit board is provided, which has a feed plate, which is connected to the multiple fuse arrangement, in particular by means of plug-in contact elements, arranged on one of its sides. The output contacts are arranged on that side of the printed circuit board which is opposite the feed plate.

Abstract: In order to render possible a compact means for power distribution and fuse protection on the basis of a printed circuit board, the apparatus has a multiple fuse arrangement (10) which comprises a plurality of fuses (14) and is connected to a plurality of output contacts (18). Furthermore, a printed circuit board (2) is provided, which has a feed plate (4), which is connected to the multiple fuse arrangement (10), in particular by means of plug-in contact elements (8), arranged on one of its sides. The output contacts (18) are arranged on that side of the printed circuit board (2) which is opposite the feed plate (4).

Abstract: A magnetic bearing is disclosed for an open-end spinning rotor having a shaft supported in a wedge-like gap formed between at least one pair of support rollers. The bearing comprises a housing for receiving the shaft, a magnet disposed in the housing to extend radially relative to the shaft, and a magnet disposed on and radially extending from the shaft axially adjacent and at a spacing from the magnet in the bearing housing. The magnets have respective poles of the same magnetic orientation disposed to face and thereby repel one another. According to the invention, a coupling connects the shaft and the magnet disposed on the shaft, the coupling being releasable in response to an axial force exerted on the shaft.
