Abstract

A device for conducting the electric current from the cathode of a hooded, transverse electrolytic cell to the anode of a neighboring cell via cathodically polarized carbon blocks in the pot of a cell, cathode bars and individual conductor bars wherein the current from each cathode bar is passed under a cell to a compensating conductor bar which runs around the neighboring cell. This compensating conductor bar is connected to each anode of the cell it runs around via a flexible conductor strip. Each anode is provided on its uppermost side with a yoke which is inserted and firmly secured in place, together with the conductor strip, in a notch or recess provided in a device for holding the anode in place. The anode holding device remains in place during anode changes and can be adjusted vertically by means of a motor or the like as a function of the voltage or the desired interpolar distance between anode and cathode.

Dependent claims

An apparatus for conducting electrical current from the cathode to the anode of transversely disposed electrolytic cells comprising:

a first electrolytic cell having a cathode;
a second electrolytic cell having at least one anode and a compensating conductor bar, said at least one anode and said compensating conductor bar being in electrical contact;
said first electrolytic cell being provided with at least one cathode bar remote from said second electrolytic cell, at least one cathode bar proximate to said second electrolytic cell and at least one conductor bar passing under said first electrolytic cell, said at least one conductor bar having one end in electrical contact with said at least one cathode bar remote from said second electrolytic cell and the other end in electrical contact with said compensating conductor bar of said second electrolytic cell;
and
said second electrolytic cell being provided with at least one conductor bar passing under said second electrolytic cell, said at least one conductor bar having one end in electrical contact with said at least one cathode bar proximate to said second electrolytic cell and the other end in electrical contact with said compensating conductor bar of said second electrolytic cell.
