PROCESS FOR THE TRANSMISSION OF ELECTRIC POWER BETWEEN PARTS ROTATING AT A LOW SPEED, AND DEVICE FOR THE USE OF SAID PROCESS

摘要

Device and method for transmission of electric power between two parts turning at low relative speed. A flexible electrical conductor connects an intermediate part to the turning. A driving device is located between the intermediate part and the turning part with clutching means and electrical switching means disposed between the intermediate and fixed parts. Control means is located between a position detector and the electrical switching means and the clutching means. Thus, when the turning part has been displaced by a certain angle with respect to the fixed part, the electrical connection is displaced so as to cancel the twist which it has undergone because of the rotation of the turning part. The connection between the fixed part and the turning part is then reestablished for another rotation.
