Abstract: Disclosed is an electromagnetically released spring pressure brake that is to be mounted on a machine wall or similar. Said brake comprises a uniform rectangular coil support (1) with two preferably oval, adjacent coils (7, 7.1), to which two separately movable rectangular armature disks are assigned. Said armature disks apply pressure to a joint rotor encompassing two friction linings that are mounted on each side when the coils (7, 7.1) are de-energized. The rotor is axially movable on an axially toothed hub. Two respective fastening screws (9) are used for guiding each of the armature disks parallel along the central longitudinal axis (13, 13.1) thereof, on the radially largest possible diameter of the rotor. A manual lever (10) featuring manual releasing bolts is provided for each armature disk.

Abstract: The invention relates to a mounting of one or more electromagnetically bleeding spring-loaded brakes (a, b) on a machine wall or the like. The invention is characterized in that the brakes are, while distributed over the periphery on the face, act upon an axially moving brake rotor (5) with continuous friction linings (6) on both sides (i.e. left and right), whereby braking (left) surface of the friction lining (6) and on the opposite side with the armature discs of the brakes on the second (right) friction lining (6).

Abstract: The invention relates to a coupling/brake combination, characterised in that the unit is embodied as a so-called lantern (connector piece) with integrated static current operated spring pressure brake and with a central hub (for example, a bellows coupling or a plug-in coupling or a shaft in hollow shaft) between the input side (motor) and output side (gearbox/spindle/or similar) and the brake is arranged on the output side (gearbox/spindle side). The unit is embodied such that both shaft levels from the input side (motor) and output side (gearbox/spindle/or similar) lie directly adjacent each other in the central hub such that the shortest possible length of the whole unit can be achieved.

Abstract: The invention relates to a drive assembly for a carriage (13) that can be displaced preferably in a vertical manner. Said assembly comprises a stationary corresponding gear rack (1), with an assigned pinion of a drive motor (22) that is situated on the carriage and comprises a fail-safe brake (23) on the B end plate, said pinion being driven by a gear (21) to displace the carriage (13) in a vertical manner. An auxiliary carriage retaining device can be engaged if necessary to secure the vertically displaceable carriage (13). To obviate the need for manual work to increase the operational safety during the set-up of the carriage and its associated machine-tool, the retaining device is located on the carriage as an auxiliary brake unit (20) and is configured to engage directly in the gear rack (1) by means of its own pinion (2), which runs along inactively during the normal displacement of the carriage (13). The brake unit (20) can be operated independently of the fail-safe brake (23) of the drive motor (22).

Abstract: A brake coupling combination for a motor, preferably an electric motor, consisting of a brake which can be attached to the motor, the brake having a flange (1) with which it is directly connected to a correspondingly shaped part of the motor, characterized in that the brake is mounted on the end of the shaft (9) of the motor by means of a hub (4) and that a flexible coupling (K) connects directly to the brake for connection to a second shaft.

Abstract: The invention relates to a torsionally rigid, play-free, metal bellows-type, flexible shaft coupling for the torque-transmissive interconnection of two shafts. A metal bellows (1) has its generally axially flanged-out ends (1′) clamped on the ends of shafts (4) for frictional engagement. For the provision of a torsionally rigid, torsionally play-free and flexible coupling which can be manufactured inexpensively, which is readily available due to a modular design and which does not affect the drive train dynamics, the ends (1′) of metal bellows (1) have clamping rings (2, 2a) placed thereon which have slots (2′) therein and are adapted to be compressed by the width of slot (2′) to preferably directly clamp the ends (1′) of metal bellows (2) down on shafts (4).

Abstract: An extruder is purged of residual thermoplastic resin by passing purging compound through the extruder, the purging compound being particles of fluoropolymer which are non-melt flowing at the temperature of operation of the extruder.
