Abstract: The invention relates to an electromagnetically ventilating spring-pressure brake for mounting on the driving disk (15) or the driving disk shaft (16) of already existing elevators, which are operated with cables passing over a driving disk. The external-mounted brake (1) is situated concentric to the central axis of the driving disk (15) or driving disk shaft (16) on a separate base (23) of the structure on the free side (i.e. opposite the driving side) of the driving disk (15) and is fastened in a stationary and rotationally fixed manner. The rotor (5) of the brake (1) is connected in an essentially rotationally fixed manner to the free end of the driving disk (15) or of the driving disk shaft (16) in order to transmit the braking torque of the external-mounted brake to the driving disk (15).

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: A rotary piston pump has at least two rotors (8) with associated drive shafts (26), wherein for each rotor (8) an associated bearing tube (28) is provided, which extends into the associated rotor (8) and through which the associated drive shaft (26) passes. Between the inside (24) of each rotor (8) and the outside of the bearing tube (28) a first gap (64) is provided. In operation, the first gap (64) contains cooling fluid and is part of a cooling fluid circuit.

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).

The metal plate is thermally connected to the semiconductor device and has a mounting surface connectible to a heat sink and a lateral surface perpendicular to the mounting surface. Contacts extend from inside the housing cup through the bottom and are firmly connected thereto. Cutouts are formed in the metal plate at the edges thereof opposite said contacts. The mounting surface of the metal plate extends beyond the wall opposite the bottom. The housing is fillable with sealing compound through the cutouts to an extent where at least part of the lateral surface of the metal plate is wetted with sealing compound.

Abstract: This invention relates to immersion ultrasonic pulse-echo testing of tubes or bars for internal defects wherein means are provided to continuously monitor the operation of the test channel. As ultrasonic energy enters the workpiece, the round workpiece surface causes acoustic energy scatter responsive echo signals which are sensed by the transmitter probe, are amplified and applied to a threshold circuit. If the amplitude of the scatter responsive signal falls below a predetermined level, an output signal indicative of "loss of operation" is produced. Means are provided to inhibit such output signal in the event of only a momentary decrease of the scatter responsive signal below a predetermined value.

Abstract: A controllable semiconductor component element has a housing of two massive metal bodies, each of which has a flange which is axially and radially embraced by an insulating ring. A semiconductor element is mounted between the metal bodies and has a cathode side and an anode side carrying a cathode and an anode, respectively which are conductively connected, with respect to heat and current, to the respective metal bodies. The anode is in the form of a ring which circumscribes a control electrode. A lead is connected to the control electrode and extends through an axial opening in the cathode side metal body to the exterior for connection, by way of spring tension, solder or the like to a control lead. The opening is completely filled with an insulating material to center and rigidly fix the lead therein. Each of the metal bodies is conically shaped, tapering away from the semiconductor element, and includes a rounded end to be received in a pressure spring.
