ABSTRACT:
A rotative coupling allows the inductive transmission of power and the transmission of informational signals between a stationary part and a hollow, rotating part. The informational signals are transmitted on a modulated beam of light passing through and along the axis of rotation of the hollow, rotative part. The power is transmitted by induction from a coil on the stationary part to a coil on the rotative part, both coils being positioned within stationary core means and the rotative core means, which combine to establish a continuous flux path around the coils.
