ABSTRACT:
Control units at each support have means for receiving function initiating signals from a communication system common to the supports, means responsive to those function initiating signals for issuing corresponding control signals to component elements of the associated support and means for transmitting data to the communication systems. A remote control unit has means for issuing control signals including such function initiating signals over the communication system, means for receiving data from the supports, means for specifying a sequential or automatic mode wherein support advancing means are successively operated sequentially, and means for displaying data from and relating to the supports. Advantageously, the sequential or automatic mode specifying means is operative relative to a preset distance, and the remote control unit further comprises means for specifying selective or manual modes wherein an individual support is selected and controlled without reference to any set sequence, one such selective or manual mode implementing the operation of the support advancing means to a, or said preset distance, and another allowing such operation without preset of its distance.
