Abstract
Abstract The present invention provides a flexible intercell connector, suitable for connecting electrolytic cells, comprising a plurality of thin conductive metal sheets having a portion of their major surfaces in a spaced relationship to one another. The conductive metal sheets are preferably joined and laminated at their opposite ends by encapsulation and fusion in a casting of conductive metal around each end. The conductive metal castings encapsulating each of the ends of the conductive metal sheets are cast in such a manner to serve as attachment means.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
76 words
A flexible intercell connector, suitable for electrically connecting electrolytic cells, comprising a plurality of thin conductive metal sheets of a predetermined length joined and laminated at their opposite ends by encapsulation and fusion to form a conductive metal casting around each end, said metal sheets comprising a stack between said castings, and having a portion of their major surfaces in a spaced relationship to one another, each sheet in said stack being progressively greater in length.
Claim 2
Dependent Claim
76 words
A flexible intercell connector, suitable for electrically connecting electrolytic cells, comprising a plurality of thin conductive metal sheets of a predetermined length joined and laminated at their opposite ends by encapsulation and fusion to form a conductive metal casting around each end, said metal sheets comprising a stack between said castings, and having a portion of their major surfaces in a spaced relationship to one another, each sheet in said stack being progressively greater in length.
Claim 3
Dependent Claim
28 words
The flexible intercell connector of claim 1 wherein said conductive metal sheets number about 4 to about 100 and are about 10 to about 250 mils in thickness.
Claim 4
Dependent Claim
28 words
The flexible intercell connector of claim 2 wherein said conductive metal sheets number about 8 to about 35 and are about 30 to about 125 mils in thickness.
Claim 5
Dependent Claim
28 words
The flexible intercell connector of claim 1 wherein said conductive metal sheets are spaced at a maximum distance of about 10 to about 250 mils between major surfaces.
Claim 6
Dependent Claim
28 words
The flexible inteRcell connector of claim 4 wherein said conductive metal sheets are spaced at a maximum distance of about 20 to about 125 mils between major surfaces.
Claim 7
Dependent Claim
25 words
The flexible intercell connector of claim 1 wherein the extent of fusion of the said conductive metal sheets is about 40 to about 100 percent.
Claim 8
Dependent Claim
13 words

Claim 10
Dependent Claim
129 words
A process for fabricating a flexible intercell connector, suitable for connecting electrolytic cells, which comprises the steps of: A. positioning a plurality of thin conductive metal sheets on top of each other; B. overbending said conductive metal sheets to a predetermined angle; C. joining and laminating the opposite ends of said conductive metal sheets while at said predetermined angle by casting conductive metals around each end of said conductive metal sheets thereby encapsulating and fusing each end of said conductive metal sheets in cast conductive metal and forming a cast conductive metal attachment means at each end of said conductive metal sheets, D. thereafter backbending said conductive metal sheets to a desired position angle thereby producing spaces between said conductive metal sheets and imparting flexibility to the intercell connector.
Claim 11
Dependent Claim
129 words

Claim 12
Dependent Claim
37 words
The process of claim 9 wherein said conductive metal sheets are of the same length and form a stepped configuration at each of their opposite ends when overbent, said conductive metal being cast around said stepped configurations.
Claim 13
Dependent Claim
25 words
