Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 152 words
An electrolytic cell of the diaphragm type, comprising, in combination, a base of an electrically insulating material, a plurality of anodes fixed on said base of said cell by means of extensions of said anodes which pass through said base, said extensions comprising at least one core of a metal which is a good electrical conductor, connecting means connected to at least one of a plurality of current distributing bars, and a rigid structure with the distributing bar and the base of the cell resting thereon, said distributing bars being disposed between said base of said cell and said rigid structure, said plurality of current distribution bars being extended by a platform located in front of said cell, from which electrical connection between cells is provided, said rigid structure resting on supports and with at least one said current distributing bar resting on said rigid structure by means of an insulating element.
Claim 2
Dependent Claim 152 words
An electrolytic cell of the diaphragm type, comprising, in combination, a base of an electrically insulating material, a plurality of anodes fixed on said base of said cell by means of extensions of said anodes which pass through said base, said extensions comprising at least one core of a metal which is a good electrical conductor, connecting means connected to at least one of a plurality of current distributing bars, and a rigid structure with the distributing bar and the base of the cell resting thereon, said distributing bars being disposed between said base of said cell and said rigid structure, said plurality of current distribution bars being extended by a platform located in front of said cell, from which electrical connection between cells is provided, said rigid structure resting on supports and with at least one said current distributing bar resting on said rigid structure by means of an insulating element.
Claim 3
Dependent Claim 21 words
An electrolytic cell according to claim 1, wherein said electrical connection between cells is provided by means of bunches of foils.
Claim 4
Dependent Claim 26 words
An electrolytic cell according to claim 1, wherein said cell also comprises a component which extends the said platform laterally and acts as a short-circuiting component.
