Fluid output end apparatus for a mercury cathode electrolytic cell

Claim 1

IN A MERCURY CATHODE ELECTROLYTIC CELL IN WHICH BRINE AND MERCURY AMALGAM CATHODE MATERIAL FLOWS, AT AN OUTPUT END, FROM A SLOT BETWEEN THE PLANAR SURFACE OF A CATHODE BASE AND AN ANODE SPACED ABOVE SAID CATHODE BASE, AN END BOX INCLUDING A FLUID ENTRY COMPARTMENT HAVING SIDE WALLS, AN ENTRY END WALL SECURED TO SAID OUTPUT END OF SAID CELL, SAID ENTRY END WALL HAVING A FLUID ENTRY SLOT THEREIN, A STEEL MERCURY AMALGAM FLOW SURFACE EXTENDING INWARDLY FROM SAID FLUID ENTRY SLOT AND EXTENDING BETWEEN THE SIDE WALLS, MEANS SECURED TO SAID FLOW SURFACE AND EXTENDING CENTRALLY THEREOF AT AN ACUTE ANGLE FROM SAID SIDE WALLS FOR RESTRICTING THE WIDTH OF THE SURFACE OVER WHICH MERCURY AMALGAM MATERIAL MAY FLOW DURING OPERATION OF THE CELL, SAID FLOW SURFACE BEING SUBSTANTIALLY ALIGNED WITH THE PLANAR SURFACE OF THE CATHODE BASE OF SAID CELL FROM THE INLET SLOT PAST THE CENTRALLY EXTENDING MEANS FOR RESTRICTING THE WIDTH OF THE SURFACE, A STRAP HAVING AN INLET SIDE AND AN OUTLET SAID DISPOSED BEYOND SAID CENTRALLY EXTENDING MEANS FOR WITHDRAWING AMALAGAM FROM SAID FLUID ENTRY COMPARTMENT, AND BRINE REMOVAL MEANS DISPOSED IN AT LEAST ONE OF SAID SIDE WALLS ABOVE THE AMALGAM INLET OF SAID TRAP.
