Abstract
Abstract An improved method and apparatus for adjusting the space between an adjustable anode and a cathode in an electrolytic cell wherein current measurements and voltage measurements are obtained for conductors to the anode sets and compared with predetermined standards for the same conductors and anode sets. Measurement 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
77 words
In a mercury cell circuit having a plurality of flowing mercury amalgam cathode electrolytic cells in series, each of said cells being electrically connected to the cells adjacent thereto by bus bars, and a control circuit having a storable program digital computer, the improvement comprising shunts responsive to current flow on each of said bus bars; and first level multiplexing means and second level multiplexing means interposed between said bus bars and said storable program digital computer.
Claim 2
Dependent Claim
77 words
