Abstract
An electrolytic cell comprised of a tank for holding electrolytic solution, and a drum rotatable about a horizontal axis having a non-conductive cylindrical outer surface disposed within the tank, and a plurality of elongated, like anodes arranged about the outer surface of the drum. The anodes together form a generally continuous cylindrical surface spaced from, and generally conforming to, the outer surface of the drum. Each of the anodes has at least one end projecting through the tank. A plurality of power sources is provided together with connection means for connecting groups of one or more of the projecting ends of the anodes to each power source.
