Abstract

Abstract 1. An electrolytic cell comprising: a concave member of dielectric material having a base; a flange integral with said base and projecting therefrom substantially adjacent the periphery thereof, said flange forming a side wall, and electrically conductive material on the internal surface of said base, said conductive material constituting a first electrode of said cell; a second electrode engaging said flange and essentially parallel to said internal surface, said second electrode covering said concave member, and forming with said concave member a chamber; a partition within said concave member, said non-conductive partition of dielectric material and said flange being so constructed and arranged as to form a continuous, inwardly turning passage for electrolyte extending from the periphery of said concave member to the center thereof; and said cell having passage means for passing electrolyte into and out of said chamber comprising an inlet adjacent one extremity and an outlet adjacent the opposite extremity of said partition.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 155 words
An electrolytic cell comprising: a concave member of dielectric material having a base; a flange integral with said base and projecting therefrom substantially adjacent the periphery thereof, said flange forming a side wall, and electrically conductive material on the internal surface of said base, said conductive material constituting a first electrode of said cell; a second electrode engaging said flange and essentially parallel to said internal surface, said second electrode covering said concave member, and forming with said concave member a chamber; a partition within said concave member, said non-conductive partition of dielectric material and said flange being so constructed and arranged as to form a continuous, inwardly turning passage for electrolyte extending from the periphery of said concave member to the center thereof; and said cell having passage means for passing electrolyte into and out of said chamber comprising an inlet adjacent one extremity and an outlet adjacent the opposite extremity of said partition.
Claim 2
Dependent Claim 155 words
An electrolytic cell comprising: a concave member of dielectric material having a base; a flange integral with said base and projecting therefrom substantially adjacent the periphery thereof, said flange forming a side wall, and electrically conductive material on the internal surface of said base, said conductive material constituting a first electrode of said cell; a second electrode engaging said flange and essentially parallel to said internal surface, said second electrode covering said concave member, and forming with said concave member a chamber; a partition within said concave member, said non-conductive partition of dielectric material and said flange being so constructed and arranged as to form a continuous, inwardly turning passage for electrolyte extending from the periphery of said concave member to the center thereof; and said cell having passage means for passing electrolyte into and out of said chamber comprising an inlet adjacent one extremity and an outlet adjacent the opposite extremity of said partition.
