Abstract
Abstract A liner of resilient material formed to fit into an electrolytic cell. The liner is a one-piece layer of polymeric or plastic material impervious to liquid electrolyte. Protrusions are provided on the outer side of portions of the liner to space the layer from the cell wall. This spacing allows drainage of the electrolyte from leaks in the layer brought about by the impacting of the electrodes against the cell wall. The protrusions also act to cushion such impacts reducing the extent of damage caused thereby.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
77 words
A resilient liner for an electrolytic cell comprising a one-piece, resilient layer, said layer being impervious to electrolytes; and a plurality of protrusions disposed on at least a portion of the exterior surface of said layer, said protrusions being conical in shape and providing passageways between said layer and the cell for drainage of electrolytes trapped therebetween, said conical protrusions having a height to base diameter ratio of approximately one-third to facilitate the fabrication of the liner.
