Abstract
To groove two regions simultaneously to different groove depths, a dual element/voltage electrode is disclosed. The electrode comprises an outer, cylindrical sheath element and an inner rod element separated by an insulator. Each element operates at a different voltage. The cylindrical element which grooves the conical bearing will, for example, operate at half the voltage of the rod element which grooves the pumping region, thereby achieving twice the groove depth.
