INDUCING AND/OR ELIMINATING POLARIZATION IN ONE CELL OF A SERIES OF CELLS IN OPERATION
First Claim
2. A method according to claim 1 wherein when the auxiliary power supply has been shutoff, the cell is momentarily shorted out from the series so that substantially no current is passing therethrough to cause virtually immediate drop of voltage across the cell to the usual or normal value when the cell has been reinstated into the series and the main current supply is again being passed therethrough.

Abstract
A procedure for inducing anode effect or polarization by subjecting an anode in a cell, in a series of cells in operation, and being subjected to a main electrical current power supply source, capable of delivering current for said operation at higher than normal voltages across at least one cell in said series, to a higher than normal current density by supplying additional current to said cell from an auxiliary or secondary current or power supply connected to and across said cell in parallel and then discontinuing current supply from said auxiliary supply, thus eliminating the anode effect induced in said cell by thus subjecting the same to a higher than normal voltage. By starting each or less than all of the cells at a time in a series of cells, the anode effect will usually occur in a cell at a time or in less than all of the cells at a time, thus lessening the strain of a number of cells polarizing simultaneously. When an increased cell voltage or voltage oscillations of increased frequency occur across a cell, it is about ready for depolarization and the recited procedure can be applied.

3. A method according to claim 1 wherein the cells in the series of cells are placed into operation at different times so that the treatment of claim 1 will ordinarily be effected for a cell at a time different from that for another cell.
