Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
An electrolytic cell which comprises: a.-a first frame member housing an electrode, b. a second frame member housing an electrode, c. a separator positioned between said first frame member and said second frame member. d. a first gasket contacting a side of said first frame member and one side of said separator, e. a second gasket contacting a side of said second frame member and having a raised portion, said raised portion contacting the other side of said separator, the area of contact between said raised portion of said second gasket and said separator being less than the area of contact between said first gasket and said separator, and f. pressing means for pressing said frames together against said gaskets and said separator so as to form a substantially fluid-tight seal.
Claim 2
Dependent Claim
131 words
An electrolytic cell which comprises: a.-a first frame member housing an electrode, b. a second frame member housing an electrode, c. a separator positioned between said first frame member and said second frame member. d. a first gasket contacting a side of said first frame member and one side of said separator, e. a second gasket contacting a side of said second frame member and having a raised portion, said raised portion contacting the other side of said separator, the area of contact between said raised portion of said second gasket and said separator being less than the area of contact between said first gasket and said separator, and f. pressing means for pressing said frames together against said gaskets and said separator so as to form a substantially fluid-tight seal.
Claim 3
Dependent Claim
13 words
The electrolytic cell of claim 1 in which said separator is hydraulically permeable.
Claim 4
Dependent Claim
13 words
The electrolytic cell of claim 1 in which said separator is hydraulically impermeable.
Claim 5
Dependent Claim
36 words
The electrolytic cell of claim 3 in which said hydraulically impermeable separator is a cation exchange membrane comprised of fluorocarbon polymers having cation exchange means selected from sulfonic acid groups, carboxylic acid groups, and mixtures thereof.
Claim 6
Dependent Claim
26 words
The electrolytic cell of any preceding claim in which said second gasket is comprised of an elastomer selected from Neoprene, Hypalon@, ethylene-propylene dimonomer, and gum rubber.
Claim 7
Dependent Claim
28 words
The electrolytic cell of any preceding claim in which said first frame member and said second frame member are in the form of C channels or U channels.
Claim 8
Dependent Claim
26 words
The electrolytic cell of any preceding claim in which said first gasket has an inset portion for insertion of said raised portion of said second gasket.
