Abstract: A laminating system for bonding, to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for de-laminating the carrier from the receiver stock after the material has been applied to the receiver stock includes a superposed sandwich of the lamination sheet and the receiver stock. A de-lamination leader is associated with one edge of the lamination sheet and the receiver, whereby the carrier can be easily peeled from the receiver stock starting at the one edge. The leader may be between the one edge of the lamination sheet and the receiver stock so that the edge does not laminate to the receiver stock upon application of heat and pressure. Alternatively, the leader may be butt joined to the one edge of the lamination sheet, such as by tape. A pair of adhesive stripes, one stripe being more adhesive than the other, may also be used to join the materials.

Abstract: A laminating system for bonding, to receiver stock, a lamination sheet of the type including a carrier, a material to be applied to the receiver stock, and a de-lamination leader associated with one edge of the lamination sheet; and for peeling the carrier from the receiver stock after the material has been applied to the receiver stock, includes a fuser through which a sandwich of receiver stock and lamination sheet, with material to be applied to the receiver stock between the carrier of the lamination sheet and the receiver stock, is fed with the de-lamination leader and the one edge facing in the direction of feed to apply the material to the receiver stock. A pair of driven nip rollers receive the de-lamination leader therebetween as the sandwich emerges from the fuser to tension the carrier, thereby breaking the bond between the carrier and the receiver stock.

Abstract: Disclosed is a method of conducting electrolysis in a bipolar electrolyzer. According to the disclosed method an electrical current is passed from anodes of a first electrolytic cell through an electrolyte to cathodes of the first electrolytic cell, evolving hydrogen at the cathodes.

The disclosed method is characterized in that the electrical current passes from the cathodes of the first cell through the bipolar unit to the anodes of the subsequent cell by first changing direction and passing laterally through a cathodic element of the backplate to conductor means between the cells, thereafter changing direction and passing through the conductor means, and then changing direction and passing laterally through the anodic element of the backplate to the anodes of the subsequent cell.

Additionally, the apparatus may interrupt the flow of catholyte liquor between the catholyte chambers of the individual electrolytic cells and the catholyte liquor trough, thereby reducing corrosion of the perc pipes. The emission limiting means and low catholyte liquor level indicating means include a top on the cell liquor trough.

Additionally, where each anode is formed from a pair of metal sheets, the anode sheets are jointed together with leachable joint at the end of the sheets spaced from the anode unit.
