DEFINITION

Classification: 205/710

With changing current:

(under subclass 705) Subject matter in which the metal or metal alloy is treated with alternating current, pulsed direct current, or any other electric current which is varied in direction or intensity during the electrolytic removal of foreign material.

(1) Note. This subclass and the subclasses indented hereunder do not include alterations in electric current which occur for or during a noncleaning treatment unless there is also some current change during the electrolytic removal of foreign material.
