Abstract
Abstract A current transmitting system for use with a self-propelled automatically steered electric vehicle includes a pair of parallel, circularly arranged bus bars connected to a low-frequency A.C. power source, an induction cable extending along the bus bars and connected to a high-frequency A.C. power source, and a current collecting shoe slidable on and along each of the bus bars for transmitting the current carried by the bus bar to an electric device mounted in the vehicle. In this system, each of the bus bars is divided into two sections one of which is connected to the low-frequency A.C. power source through a coil.
