Abstract: Electrolytic diaphragm cells are provided comprising a plurality of vertical substantially flat and hollow anodes formed, as regards at least one of their two substantially parallel faces, by a sheet of a film-forming metal, said anodes being secured to the base of the cell by means of extended portions which pass through the base, characterized in that the extended portions comprise a core made of a metal which is a good electrical conductor, which core is covered by a sheath made of a filmforming metal, a good electrical contact being ensured between the sheath and the core. The core of the extended portions is exposed where it passes through the base of the cell, with the electrical connection between the base and the core comprising resilient metal parts arranged between the core and the base.

Abstract: Processes for the electrolysis of alkali halides employing dismantleable bipolar electrodes are provided of which the anodically active portion comprises titanium or other filmforming metal or alloy of similar anodic properties covered with a conducting layer, and of which the cathodically active portion comprises a common metal such as mild steel. Said electrodes are characterized by the separation in space of said active portions, at least one of which is apertured or foraminous, and by the electrical connection between said portions, which is achieved by means of two series of parts, each of said series being mechanically and electrically secured to one of said portions, the corresponding parts of each series being of shapes such that once connected in order to form pairs of parts, said pairs have a sealed cavity for housing a device or means for establishing electrical contact between the two parts of each pair. These electrodes are particularly suited for being mounted in cells of the filter-press type, for the electrolysis of brines.

Abstract: Bipolar electrodes are provided having an anodically active part comprising a film-forming metal covered with a conducting layer which is inert to electrolytes, and a cathodically, active part comprising a metal which can be used cathodically, said anodically and cathodically active parts being separated in space and connected together by an electrical connection, characterized in that the two electrolytically active parts are apertured, that the electrical connection between them is made through the contact formed within a plurality of bonded members produced by plating a metal which can be used cathodically with a filmforming metal, and that said bonded members are part of a sealing partition separating the two electrolytically active parts.
