Electrolytic process and apparatus
First Claim
1. An electrolytic process in which depositions on the cathode are removed by periodically rendering the polarity of the cathode anodic, comprising(a) using at least one anode and at least two electrodes which can function as cathodes;
- (b) passing an anodic current through the anode so that the anode always remains the anode;
(c) passing a portion of the anodic current through an electrode which can serve as a cathode to remove deposits formed thereon;
(d) passing a cathodic current through the other electrode which can serve as a cathode; and
(e) periodically changing the polarity of the electrode functioning as a co-anode and the electrode functioning as a cathode, characterized by the step ofperiodically reversing the polarity of the electrode functioning as a co-anode and the electrode functioning as a cathode in cycles having a period of between 80-330 minutes.

Abstract
Method and apparatus for electrolyzing halogen salt solutions having a low halogen salt concentration with direct formation of halogen, using an electrolytic cell comprising at least one anode and at least two electrodes which can function as cathodes. The anode is permanently connected as an anode, a portion of the anodic current is passed through one electrode which can function as a cathode, and a cathodic current is passed through the other electrode which can function as a cathode. The polarity of the electrode functioning as a co-anode and of the electrode functioning as a cathode is periodically changed in cycles of 80-330 minutes.
