Abstract: A voltage control circuit for electrically coupling a field device coupler to a bus line. An input voltage (UE) provided at the voltage control circuit by the bus line is converted into an output voltage (UA) that can be regulated and limited. If a current limitation is additionally provided, the “inherent safety” ignition protection type can be achieved. The voltage control circuit has a chopper-type regulator without galvanic isolation. A parallel path is formed parallel to the chopper-type regulator by a series connection of two buffer capacitors. Communication signals of higher frequency can be transmitted past the chopper-type regulator via the parallel path. The parallel path and a reference terminal of the chopper-type regulator are additionally connected via an impedance circuit to a reference potential at a second input terminal of the voltage control circuit.

Abstract: The invention relates to an assembly (14) of a cable-connecting device (10) and a multi-core cable (11), which form a mechanical, explosion-proof connection to each other. For this purpose, the cable-connecting device (10) has a plastically deformable outer sleeve (18) having a crimping section (23). A hollow cylindrical inner sleeve (19) made of elastically deformable material is arranged between a cable sheath (13) made of elastomer and the crimping section (23). An elastic deformation of the inner sleeve (19) and of the cable sheath (13) is caused by radially plastically deforming the crimping section (23). Any gaps (40) present within the cable sheath (13) are closed due to the radial forces in the crimping section (23) such that spark-gap-free contact between the cable sheath (13) and the cores (12) of the cable (11) and between the cable sheath (13) and the inner sleeve (19) is ensured.

Abstract: A cable hoist having an emergency braking arrangement comprising a dual toothed wheel assembly driven via a cable drum of the hoist. One of two toothed wheels of the toothed wheel assembly is sensed by a sensing lever of an anchor and an opposite end of the anchor interacts with a ratchet wheel of the toothed wheel assembly. As soon as an over speed occurs, the anchor engages in the ratchet wheel and causes a rotary movement of a carrier on which the anchor is mounted. This rotary motion is used to trigger a mechanical braking arrangement coupled to the cable drum.
