DEFINITION

Classification: 205/709

With solid-workpiece moving contact (e.g., brushing, etc.):

(under subclass 705) Subject matter in which a workpiece of the metal or metal alloy is contacted with a relatively moving solid object (e.g., brushing, etc.).

(1) Note. This subclass includes the relative moving contact of two or more workpieces. Solid-workpiece moving contact may occur at any time before, during, or after the electrolytic treatment; and need not result in mechanical removal of foreign material from the metal or metal alloy workpiece, provided that there is relative movement between the workpiece and a contacting solid object. The relative moving contact of a conductive brush against the workpiece for sliding electrical contact is appropriate for this subclass, but the use of idling rollers contacting the workpiece and moving only therewith are classified below on some other basis.
