Abstract
Abstract The invention relates to a cylindrical type cell employing an outer active metal anode, a separator and an inner disposed cathode or cathode collector in the form of at least two arcuate bodies, said cathode or cathode collector having outward resilient biasing means for providing continuous physical contact between the anode-separator-cathode or cathode collector interfaces.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
An electrochemical cell comprising a container; an anode disposed within said container; a porous separator disposed within and in surface contact with said anode; a cathode collector in the form of at least two arcuate bodies disposed within said separator; means for biasing said arcuate bodies radially outward against said separator which in turn contacts the anode; and a liquid, active reducible cathode-electrolyte disposed within said container.
Claim 2
Dependent Claim
67 words
An electrochemical cell comprising a container; an anode disposed within said container; a porous separator disposed within and in surface contact with said anode; a cathode collector in the form of at least two arcuate bodies disposed within said separator; means for biasing said arcuate bodies radially outward against said separator which in turn contacts the anode; and a liquid, active reducible cathode-electrolyte disposed within said container.
Claim 3
Dependent Claim
24 words
The cell of claim 1 wherein the cathode collector is in the form of two arc segments each ranging from about 140° to 180°.
Claim 4
Dependent Claim
24 words
The cell of claim 1 wherin the cathode collector is in the form of three arc segments, each ranging from about 90° to 120°.
Claim 5
Dependent Claim
40 words
The cell of claim 1 wherein the means for biasing the arcuate bodies of the cathode collector radially outward is a substantially "U" shaped spring member in contact with and disposed axially within an opening defined by said arcuate bodies.
Claim 6
Dependent Claim
39 words
The cell of claim 1 wherein the means for biasing the arcuate bodies of the cathode collector radially outward is a generally cylindrical spring member in contact with and disposed axially within an opening defined by said arcuate bodies.
Claim 7
Dependent Claim
67 words
The cell of claim 1 wherein the means for biasing the arcuate bodies of the cathode collector radially outward is an elongated spring strip embedded longitudinally in the arcuate bodies such that when the arcuate bodies are arranged in an opposing fashion to form a cylinder type configuration, the strip extending between the end faces of adjacent arcuate bodies will be bent into a "U" shaped configuration.
Claim 8
Dependent Claim
47 words
The cell of claim 1 wherein the means for biasing the arcuate bodies of the cathode collector radially outward is a cylindrical spring in which a longitudinal portion of said spring is embedded longitudinally within each of the arcuate bodies thereby forming an overall substantially cylindrical configuration.
Claim 9
Dependent Claim
40 words
The cell of claim 4 wherein said substantially "U" shaped spring member is a conductive member and wherein at least one of the legs of said substantially "U" shaped spring member is secured to the positive terminal of the cell.
Claim 10
Dependent Claim
40 words
The cell of claim 5 wherein said spring member is conductive and wherein a conductive tab is secured at one end of said spring and the other end of the tab is secured to the positive terminal of the cell.
Claim 11
Dependent Claim
46 words
The cell of claim 6 wherein said elongated spring strip is a conductive strip and wherein at least one end of the elongated spring strip extends beyond the end face of one of the arcuate bodies and is secured to the positive terminal of the cell.
