Abstract
Abstract An electrode assembly adapted for arrangement between the terminal monopolar electrodes of a multipolar electrolytic cell includes a compartment wall, an anode carried by a lateral surface of the wall and provided with means for movement of the anode in a direction toward an opposed cathode surface to maintain a narrow gap between the electrodes and improve the cell power efficiency; a cathode carried by the opposed lateral surface of the same compartment wall and optionally provided with means for movement in a direction toward an opposed anode surface for maintenance of a narrow spacing of the electrodes. The electrode assembly provides for the construction of electrolytic cells of the membrane or diaphragm or diaphragm-less types which are useful for production of chlorine and caustic and for various other products of electrolytic processes.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A generally planar bipolar electrode assembly adapted for closely spaced parallel series arrangement intermediate to the terminal monopolar electrodes of a multipolar electrolytic cell having side, bottom and end walls, comprising: an electrically non-conducting, liquid tight partition, at least one rigid electrical conductor extending through said partition and beyond each lateral surface thereof; a dimensionally stable anode and a cathode connected to the rigid conductor on opposite sides of and parallel to the partition; movable, resilient, electrically conductive means connecting the non-working lateral surface of one electrode to the rigid conductor, the movable, resilient means being capable of causing movement of the lateral working surface of the electrode in a direction toward the working lateral surface of an opposed electrode of opposite charge of an adjacent bipolar assembly while maintaining intraelectrode electrical integrity.
