Abstract: An arrangement and method for detaching an adhering charge from an inner wall of a grinding tube, wherein the grinding tube is rotated backwards in a drive-free manner from a pre-determinable, assumed rotary position by the weight force of the adhering charge, where at least one movement state variable of the grinding tube is detected and the grinding tube is braked while being rotated back in dependence on the at least one detected movement state variable in order to detach the adhering charge from the inner wall of the grinding tube, and where the arrangement includes a detecting device, a drive unit, a braking device and a control device.

Abstract: The invention relates to a method and an apparatus for bidirectional transmission of electronic data in a television data cable network having segments which each comprise two or more user interfaces, with each of the segments being connected via a cable connection to a feed point in the television data cable network. In the method, electronic downlink remote data is transmitted in a downlink radio-frequency band in an upper cut-off area of a transmission bandwidth of the cable connection, and electronic uplink remote data is transmitted in an uplink radio-frequency band in the upper cut-off area of the transmission bandwidth of the cable connection.
