Abstract: An overhead plural conductor trolley rail and flying pickup for supplying electrical power to a vehicle includes a plastic extrusion fastened to an overhead structure housing parallel flat conductors, the exposed underside of each of the conductors being engaged by shoes carried on vehicle supported trolley units. At one end of the rail a guide structure for the trolley includes a central, side skirted or inverted channel shaped portion, flanked at either end by oppositely extending side-skirted ramps each inclined upwardly from the central portion. The approach ramp also diverges horizontally outwardly of the rail support. To accurately engage the trolley carried shoes with the rails, the operator need only insure that the trolley enters the divergent portion of the guide at its widest open end.

Abstract: In a current supply system for wheeled vehicles which includes a DC generating device and substantially parallel running over-head lines provided with current collectors, a closed AC circuit is provided which is independent of the current collector and includes an AC generating device which feeds the over-head lines, as well as a device connecting the lines together. The DC and AC generating device includes a first rectifying device which is connected to a three-phase AC network and a generating DC network with a superposed AC component.
