Abstract
A gasket for preventing fluid flow from the interior to the exterior of a chamber is disclosed in which tab members or projections from a body portion lockingly cooperate with corresponding recesses in the chamber wall. Transverse openings in the gasket body allow access to the interior of the chamber. The apparatus is particularly applicable as a means for sealing an electrode terminal extending from the interior to the exterior of an electrodialysis filter press stack.
Claims13
A gasket device for sealing an opening in a chamber wall to prevent the flow of liquid through said opening, said gasket comprising in combination:
- a. a body portion arranged to substantially fill said opening;
- and
- b. upper and lower tab members of elastic material joined to and extending from said body portion, at least a portion of the edges of said tab members adapted to lockingly cooperate with corresponding recesses in said chamber wall to prevent the flow of liquid past the interface of said edges and said recesses.
In a filter press electrodialysis apparatus, an electrode support frame and gasket assembly comprising in combination:
- a. a rigid electrode support frame having an opening in one side extending from the interior to the exterior of said frame, said frame further having a pair of recesses one each disposed on opposite sides of said opening;
- and
- b. a gasket of elastic material comprising:
- 1. a body portion arranged to substantially fill said opening;
- and
- 2. a pair of tab members one each positioned on opposite sides of said body portion, said tab members arranged to substantially fill said recesses, at least a portion of the edges of said tab members adapted to lockingly cooperate with the edges of said recesses to prevent fluid flow past said edges from the interior to the exterior of said frame.
