## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

An apparatus according to claim 1 wherein said compensating conductor bar is ring-shaped and extends around said second electrolytic cell at a height substantially equal to the height of the pot of said second electrolytic cell.

### Claim 3 (depends on 1)

An apparatus according to claim 1 further including a flexible conductor strip leading from said compensating conductor bar to said at least one anode.

### Claim 4 (depends on 3)

An apparatus according to claim 3 further including an anode holding device for suspending said at least one anode in said second electrolytic cell, said flexible conductor strip being in electrical contact with said anode holding device.

### Claim 5 (depends on 4)

An apparatus according to claim 4 further including a yoke member secured to the uppermost surface of said at least one anode such that said flexible conductor strip is in electrical contact with said yoke.

### Claim 6 (depends on 5)

An apparatus according to claim 5 wherein said anode holding device includes means for receiving said yoke and said flexible conductor strip.

### Claim 7 (depends on 6)

An apparatus according to claim 6 wherein said means for receiving comprises a recess.

### Claim 8 (depends on 7)

An apparatus according to claim 7 wherein said anode holding device includes a first element and a second element telescopically received within said first element, said first element and said second element being capable of movement relative to each other.

### Claim 9 (depends on 8)

An apparatus according to claim 8 wherein said second element comprises a holding rod and said first element comprises a clamping sleeve for securing said flexible conductor strip in said recess between said yoke and said clamping sleeve.

### Claim 10 (depends on 9)

An apparatus according to claim 9 wherein said first element is threadably received on said second element.

### Claim 11 (depends on 8)

An apparatus according to claim 8 wherein said first element comprises a hollow holding rod and said second element comprises a clamping pin for securing said flexible conductor strip in said recess between said yoke and said clamping pin.

### Claim 12 (depends on 11)

An apparatus according to claim 11 wherein said second element is threadably received in said first element.

### Claim 13 (depends on 1)

An apparatus according to claim 1 wherein said first electrolytic cell is provided with a plurality of cathode bars remote from said second electrolytic cell, a plurality of cathode bars proximate to said electrolytic cell and a plurality of conductor bars equal in number to said plurality of cathode bars remote from said electrolytic cell wherein each of said plurality of conductor bars is in electrical contact with one of each of said plurality of cathode bars remote from said second electrolytic cell wherein all of said current is passed to said second electrolytic cell by said plurality of conductor bars.
