Abstract: An improved method for automatic adjustment of anodes in an electrolytic cell is described which utilizes the measurement of the rate of change in current density for a given unit of distance when a minor fraction of the anodes are lowered toward the liquid cathode. When the change in rate of current density exceeds a predetermined limit, movement of the minor fraction of anodes is stopped, and another minor fraction of anodes is adjusted.After positioning of the anodes is completed, control of the space between the anode and cathode is effected wherein current measurements and voltage measurements are obtained and compared with predetermined standards. Measurements of deviation from the predetermined standards are used to determine the direction of anode adjustment. A digital computer operably connected to motor drive means adapted to raise or lower anode sets upon appropriate electric signals from the computer is a preferred embodiment of this invention.

Abstract: A multi-component metal electrode and a method for its preparation is described in which a film-forming metal base such as titanium is coated with an oxide of a film-forming metal, and then further coated with a conductive oxide, such as ruthenium oxide. A corrosion resistant oxide such as tantalum oxide, is applied to the ruthenium oxide.The corrosion-resistant metal oxide is formed by applying to the ruthenium oxide a solution of an inorganic compound of the corrosion-resistant metal, and heating the solution-coated electrode to evaporate the solvent and form a corrosion-resistant metal oxide.The resulting multi-component metal electrode of this invention can be used as an electrode in mercury cells and diaphragm cells.
