A series of gear motors, a gear motor, and a planetary-gear stage includes planet wheels that mesh with a sun wheel and inner gear teeth provided for the gear housing. The planet wheels are supported in a rotatable planet carrier, which forms the power take-off, and to which a sealing element is assigned on the output side. The planetary-gear stage is assigned a further sealing element on the input side. The gear housing is shaped on the input side such that an interface is formed for connection to further components, which include at least one shaft connected to the sun wheel.

A dual chain hoist having a lifting beam that can be telescopically extended and contracted, wherein load chains respectively extend to hook blocks suspended beneath the lifting beam in the vicinity of the ends of two telescoping sections that form the lifting beam. The distance between the telescoping sections can be varied with another chain. The chain for varying the length of the lifting beam extends over a chain wheel that is connected without rotational play to another chain wheel from which the load chain of the hook block of the respective telescoping lifting beam section.

A transmission system is indicated for digital signals combined into a multiplex signal, and a network element for such a transmission system. Each network element contains an adapter circuit to balance phase variations in an incoming multiplex signal. The adapter circuit has a buffer memory (1) for payload data bytes, a write address generator (2) which controls the buffer memory (1) in a way so that a number of payload data bytes is stored within one write cycle, and has a read address generator (3) which controls the buffer memory (1) in a way so that the number of payload data bytes stored within the write cycle is greater than the number of payload data bytes read during the read cycle. Each network element has a sort facility (5) which sorts the read payload data bytes, so that a multiplex signal that is transmitted by a network element has the established frame format.

The invention concerns a network element and an input-output unit (1) for a synchronous transmission system according to the standard for Synchronous Digital Hierarchy or according to the comparable Synchronous Optical Network (SONET) standard. The input-output unit (1) contains a signal processing device (2) that has a reception data memory (5), a transmission data memory (7), a control unit (6) and a processor (3). The processor (3) is a digital signal processor which essentially carries out the processing of a STM-N signal.
