Abstract
This invention relates to a device for advancing an electrode-holder elem in particular mounted on a pulse generating apparatus of the type described in U.S. Pat. No. 2,559,227 to Rieber. This advance device comprises a radially projecting element fast with the rear part of the electrode-holder element and a member for controlling same, the radially projecting element being formed by a toothed wheel of fixed axial position with respect to the insulating support and controlled in rotation by two pistons mounted symmetrically on either side of the wheel to control a rotation in both directions. This device allows a greater precision of the advance of the electrode and an increase in the efficiency of destruction of the targets.
