Abstract: A connecting device for fastening holders, in particular lateral guide holders, to a frame profile of a conveying device for transporting unit loads includes, on one side, a linking arrangement and, on the other side, a mounting limb, wherein the linking arrangement is arranged on the holder and the mounting limb is arranged on the frame profile. For fastening the linking arrangement to the frame profile, the linking arrangement has a connecting element and a locking element, wherein the connecting element is insertable into a first hole on the mounting limb, wherein a rotation axis is defined about which the linking arrangement can be rotated until the locking element latches in a second hole on the mounting limb and locks the connecting device.

Abstract: A rotating data transmission device for transmitting data from a data source to a data sink between a rotating part and a stationary part comprises a transmitting conductor arrangement which is fed from a transmitter means, and also a receiver means which taps signals from the transmitting conductor arrangement with the aid of a receiving coupler arrangement. The connection between data source and rotating data transmission device, or rotating data transmission device and data sink, is effected by means of light-waveguides. The receivers of the light-waveguides are linear receivers followed by equalizers for correcting the frequency and phase response.
