Abstract: A safety device (10, 30, 40, 50), in particular a safety control apparatus and/or a safety diagnosis apparatus, for industrial automation, including a logic voltage zone (4), a load voltage zone (5) which is galvanically separated from the logic voltage zone (4), a transmission unit (6) for transmitting a communication signal between the logic voltage zone (4) and the load voltage zone (5) whilst maintaining the galvanic separation, a first voltage supply connection (7) for providing a first supply voltage (V1) for the logic voltage zone (4) and a first current limitation element (8), wherein the transmission unit (6) is connected on the first voltage supply connection (7) via the first current limitation element (8) and is fed from the first voltage supply connection (7) via the first current limitation element (8).

Abstract: An automated change speed gearbox is provided.

Abstract: Warp knitting machine, in particular stitch-bonding machine, a drive for the operation of a row of knitting needles and at least one row of guide needles. The drive for the row of knitting needles and the drive for the performance of oscillatory motions of the row of guide needles are each connected with a separate drive shaft, and the drive shaft of the drive for the oscillatory motions is located under or behind the working plane of the row of knitting needles and before the finished goods and is furnished with a plurality of units of drive means, distributed over the working width of the machine, for the oscillatory motions.
