Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
51 words
An electrolysis cell having bipolar elements arranged side by side, comprising an assemblage of a plurality of units of bipolar elements whose cohesion is ensured by individual assembly means on each unit, each said assembly means joining each unit to the next, said assembly means comprising positioning, attachment and clamping means.
Claim 2
Dependent Claim
51 words
An electrolysis cell having bipolar elements arranged side by side, comprising an assemblage of a plurality of units of bipolar elements whose cohesion is ensured by individual assembly means on each unit, each said assembly means joining each unit to the next, said assembly means comprising positioning, attachment and clamping means.
Claim 3
Dependent Claim
25 words
An electrolysis cell according to claim 1, wherein said positioning means consist of wheels attached to the end of each said unit of bipolar elements.
Claim 4
Dependent Claim
20 words
An electrolysis cell according to claim 2, wherein said wheels ride on rails fixed on the base of said cell.
Claim 5
Dependent Claim
84 words
An electrolysis cell according to claim 1 wherein said attachment and clamping means consist of at least one element integral with each unit having a movable system connected to preadjustable elastic linking means, comprising a female element which can mate with a movable male element in an assembly integral with an adjacent unit, the said male and female elements being adapted so that the insertion of the male element into the female element produces compression of the elastic means carried by the movable system.
Claim 6
Dependent Claim
17 words
An electrolysis cell according to claim 4 wherein said elastic linking means consist of a leaf spring.
Claim 7
Dependent Claim
13 words
An electrolysis cell according to claim 4, wherein said male element is threaded.
