A larry car, a quenching car, a pusher and other such accessory machines travel along the length of a coke-oven battery. Each coke oven is provided with coded structure absolutely indicative of the oven-number of the oven within the battery. The travelling accessory machines are provided with code readers which sense the coded structures and transmit oven-number feedback signals to a central control station. The travelling machines also transmit operation-completed signals upon completion of the individual operations of charging, pushing and the like. A programmed control system at the control station transmits travel-command and operation-command signals in preprogrammed sequences, but the transmission of these command signals is dependent upon the reception of predetermined feedback signals, which establish interlocks serving as conditions precedent to the travel of accessory machines and to their performance of individual operations.

The invention relates to a band clamp (1) for connecting a hose or pipe end (2) to a pipe (3). Said band clamp comprises flange sections (4,5) which are located opposite each other and which are essentially radially set apart. The band clamp (1) is clamped around the connection on said flange sections, with means for preventing the band clamp material from creeping under stress being configured in the area of at least one of the flange sections (4,5). A sliding segment for preventing leaks is also provided.

A contour collimator for radiation therapy has a plurality of diaphragm elements that are movable with respect to each other by means of drive units. The diaphragm elements of the invention are supported only on the side near the drive units for ease of movement. This allows larger contour collimators to be constructed having relatively heavy diaphragm elements while retaining relatively small motors.
