ABSTRACT:
An apparatus having a stationary part and a movable part, with an electrical conductor running between one or more components on each part, includes a mechanism for winding and unwinding the electrical conductor as the movable part is moved relative to the stationary part. The mechanism includes a rotatable drum onto which, and from which, both the electrical conductor and a cable can be wound or unwound in opposite winding directions. By exerting a tensile force on the conductor, the conductor can be unwound from the drum while the cable is being wound onto the drum. Conversely, the cable can be unwound from the drum while the conductor is being wound onto the drum, given a tensile force on the cable. If both the cable and the conductor are mechanically connected to the movable part, the forces acting on the movable part during winding or unwinding of the conductor balance substantially to zero.
