Abstract: In the case of a wind power installation with at least one wind turbine and one current generator device, the current generator device has at least two generators. The generators are coupled to one another via at least one differential gear unit, the wind turbine being arranged on a balancing gear of the differential gear unit. The rotors of the generators are in each case connected to an axial gear of the differential gear unit, the stators of the generators being connected to one another to form an abutment on which the differential carrier of the differential gear unit is accommodated such that it can rotate.

Abstract: The invention relates to a cutting machine, in particular a tread cutting machine, having at least one cutting blade (8) linearly traversable on a blade carriage (1) for achieving a feed movement and rotationally driven by a motor (2), the motor (2) for the drive of the cutting blade (8) being arranged outside the blade carriage (1), and a torque-transmission means, which comprises a means for transmitting tensile forces, being provided between the motor (2) and the cutting blade (8), and that part of the torque-transmission means which is traversable with the blade carriage (1) having a markedly lower mass than the motor (2). In this case, the motor (2) is provided with a device which is designed as a closed-loop control or an open-loop control and is intended for keeping the rotational speed of the cutting blade (8) at least approximately constant during a feed movement of the cutting blade (8).

Abstract: The invention relates to a sintered material as friction material for a pole shoe, a pole shoe area or at least an area of the pole shoe friction surface of a magnetic track brake (300), more particularly an eddy current brake and/or magnetic track brake with a magnetic basic and/or carrier member.

Abstract: A sintered material is used as a friction material for a pole shoe area of a magnetic track brake, having at least one of a magnetic basic member and a carrier member. The sintered material contains at least one of a proportion of pulverized wear inhibitor and a proportion of powder forming a protective layer.

Abstract: A magnetic brake, particularly a linear eddy-current brake for rail vehicles, having a magnet yoke which extends substantially along the whole eddy-current brake, has a concave shape with respect to a plane rail in its installed position.

Abstract: A magnetic rail brake, particularly an eddy current brake for rail vehicles, has at least one exciter coil which comprises a coil around a pole core as well as a device for holding the coil and/or for the protection against outside environmental influences. The pole core and/or protection device are composed of individual components which are at least largely electrically insulated with respect to one another.

Abstract: A shaft stop bushing (1) is proposed which is retained in a given position on a shaft (6) by means of a radially resilient stop ring (12). The stop bushing (1) has a longitudinal bore (4) with two circular grooves (7 and 11) of different diameters, between which a funnel-shaped section (10) is formed. The stop ring (12) is inserted in the larger groove (11) so that stops bushing (1) and stop ring (12) form a pre-assembled subassembly (1, 12). The preassembled subassembly (1, 12) can be slid onto the shaft (6) by a simple automatized process without the stop ring (12) touching the shaft (6). The stop ring (12) is retained in its axial position relative to an annular groove (16) of the shaft (6) and is pressed into the annular groove (16) by the stop bushing (1) upon further axial movement of the stop bushing. The entry funnel-shaped section (10) presses the stop ring (12) until, in the assembled state, the smaller-diameter circular groove (7) engages over the stop ring (12).

Abstract: To provide an easily manufactured ignition distributor in which two bearings support the distributor shaft, the lower bearing is molded or otherwise secured into the housing structure, whereas the upper bearing is supported on a transversely extending support member, typically a support plate which is seated within the housing, for example bearing against a shoulder, against seating lugs, or the like, so that the entire ignition distributor structure can be constructed with small compact size.

Abstract: An annular permanent magnet affixed to the bottom of the timing shift plate of an ignition distributor exerts a force attracting the timing shift plate to the fixed carrier plate on which the timing shift plate is supported by spacers. Another permanent magnet is set into the inner flange of the carrier plate in the neighborhood of the cam-following portion of the interruptor to attract the nesting inner flange of the timing shift plate, so as to prevent the play between these flanges which form the bearing for the timing shift plate from interfering with the ignition timing. The timing shift plate and carrier plate are made of iron and there is only a small gap between the outer peripheries to provide a return magnetic circuit.
