Abstract
Abstract A novel circuit of electrolytic cells comprising novel electrolytic cells, novel jumper switches and novel arrangement of the jumper switches referring to the electrolytic cells which enable the novel circuit to be designed to operate at high current capacities upward to about 500,000 amperes while maintaining high operating efficiencies. These high current capacities provide for high production capacities which result in high production rates for given cell room floor areas and reduce capital investment and operating costs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A circuit of electrolytic cells installed in electrical series, comprising: a plurality of vertical electrode cells whose aspect ratio of cell length to cell width is at least 2:1, said cells being disposed in at least one row so that the anode lead-in and cathode lead-out busbars are disposed along the length of each cell, said cell circuit containing at least one portable jumper switch beneath a cell row and movable along the center line of the cell row, said portable jumper switch having cell connectors on opposite sides, said jumper switch permitting that a cell may be taken out of service by conducting the current through the jumper switch without interrupting continuous operation of the other cells in the circuit thereby ensuring that the electric current flow through said connectors of the jumper switch from one cell to the other cell connected to the jumper switch is rectilinear in the top view of the cell row.
Claim 2
Dependent Claim
157 words
A circuit of electrolytic cells installed in electrical series, comprising: a plurality of vertical electrode cells whose aspect ratio of cell length to cell width is at least 2:1, said cells being disposed in at least one row so that the anode lead-in and cathode lead-out busbars are disposed along the length of each cell, said cell circuit containing at least one portable jumper switch beneath a cell row and movable along the center line of the cell row, said portable jumper switch having cell connectors on opposite sides, said jumper switch permitting that a cell may be taken out of service by conducting the current through the jumper switch without interrupting continuous operation of the other cells in the circuit thereby ensuring that the electric current flow through said connectors of the jumper switch from one cell to the other cell connected to the jumper switch is rectilinear in the top view of the cell row.
Claim 3
Dependent Claim
44 words
A circuit of electrolytic cells according to claim 1 wherein the support means of the cells and the support structure carrying the cells are located outside the switch operating area permitting installation, movement and operation of the portable jumper switch beneath the cell row.
Claim 4
Dependent Claim
24 words
A circuit of electrolytic cells according to claim 2 wherein the support structure supporting the cells is also used for supporting the cell gangways.
Claim 5
Dependent Claim
27 words
A circuit of electrolytic cells according to claim 2 wherein the support structure carrying the cells is also used for supporting the piping of the cell room.
Claim 6
Dependent Claim
28 words
A circuit of electrolytic cells according to claim 1 wherein the anode lead-in and cathode lead-out busbars are uniformly disposed across substantially the entire length of the cells.
Claim 7
Dependent Claim
37 words
A circuit of electrolytic cells according to claim 1 wherein the anode lead-in and cathode lead-out busbars are provided with separate electrical contact areas for the cell to cell connection and for the cell to switch connection.
Claim 8
Dependent Claim
49 words
A circuit of electrolytic cells according to claim 1 containing at least one portable jumper switch, said jumper switch comprising a plurality of flexible cell connectors, a plurality of switch contacts all evenly disposed across substantially the entire length of the switch corresponding to the length of the cell.
Claim 9
Dependent Claim
27 words
A circuit of electrolytic cells according to claim 1 wherein means supporting the crossover busbars are arranged to be located below the level of the cell gangway.
