Electrolytic cells of the liquid electrode type

Claim 1

AN ELECTROLYTIC CELL OF THE MERCURY CATHODE TYPE CAPABLE OF OPERATING AT HIGH ELECTROLYTE VELOCITIES, COMPRISING AN ELONGATED RECTANGULAR TROUGH-LIKE BASE HAVING A FLAT BOTTOM SECTION WHICH CARRIES A MERCURY ELECTRODE UPON ITS UPPER SURFACE, A LONGITUDINAL CHANNEL IN SAID BASE ALONG THE LENGTHWISE SIDES OF SAID BOTTOM SECTION, A PLATE-LIKE COVER EXTENDING ACROSS THE CELL BEYOND THE EDGES OF THE MERCURY ELECTRODE HAVING AN INTEGRAL SKIRT DEPENDING THEREFROM INTO SAID CHANNEL, AN INFLATED, RESILIENT TUBE DISPOSED BETWEEN A SIDE OF THE CHANNEL WALL AND SAID SKIRT, A SOLID ELECTRODE EXTENDING ACROSS THE INSIDE OF THE CELL WITHIN THE CONFINES OF SAID COVER, SAID SOLID ELECTRODE BEING CARRIED BY THE COVER WITH ITS UNDERSURFACE DISPOSED A SHORT DISTANCE ABOVE THE UPPER SURFACE OF THE MERCURY ELECTRODE AND SUBSTANTIALLY PARALLEL THERETO CONDUITS FOR WITHDRAWAL OF GAS FROM THE INTER-ELECTRODE SPACE EXTENDING THROUGH SAID SOLID ELECTRODE AND SAID COVER, ALL FREE SPACE WITHIN THE INNER CONFINES OF SAID COVER ABOVE THE LEVEL OF THE ANODE UNDERSURFACE, ASIDE FROM SAID CONDUITS, BEING FILLED WITH SOLID MATERIAL, AND MEANS EXTERNAL OF THE CELL FOR ADJUSTING THE INTER-ELECTRODE SPACE BY MOVEMENT OF SAID COVER RELATIVE TO SAID BASE.
