DEFINITION

Classification: 204/224

Electrolytic apparatus wherein means are provided to localize the areas to which electrolysis is applied.

(1) Note. This group of patents include portable coating electrodes, cells and half-cells specialized for localized application of the electrolytic coat; however, the subclass is not limited thereto but includes stationary devices in which the electrode or electrodes alone are moved to localize electrolytic action.
