Abstract
Abstract An adjustable electrode for use in electrolytic cells is provided. The electrode comprises two electrode surfaces positioned in parallel and having a space between them. A rotatable element is attached to each of the electrode surfaces. Upon rotation of the element, the space between the electrode surfaces may be varied. Variation in the space between electrode surfaces is desirable when assembling the electrodes in the cell and in providing the optimum gap between electrodes of opposite charge. The adjustable electrode is employed in cells for providing chlorine and caustic soda or oxychlorine compounds by the electrolysis of alkali metal chloride solutions.
