mthe cell. Each square foot of the cathode area in thecell has a current density of twenty amperes. Thecathodes are removed every twenty-four hours and av-erage 210 lb. to the cell. The strippers pull six cathodesfrom the cell at one time by means of a one-ton chainblock hooked to a frame which fits under the hook-shaped lugs and tightens up under them when theframe is raised. The pull of six cathodes, as it iscalled, is carried to a stationery steel stripping frameat the lower end of the cell room by means of the blockrunning on an overhead steel trolley. The cathodesare held in the stripping frame while the stripper in-serts a sharp chisel between the zinc and the aluminumcathode and peels off a sheet of zinc about -h in. thick.These sheets are piled near the stripper and thentrammed to the furnace room. Wooden strips whichstick tightly to the edges of the cathode are used to stopirregular deposits and make the zinc easier to handle. Because the amount of current carried by the cell

The busbars are 1.25 in. thick,4 in. wide, and taper to i in. wide in the length of thecell. The busbars holding the electrodes are on theoutside of the cell, the anode bar being on the inside 1122 Engineering and Mining Journal Vol. 110, No. 24
