Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
AN ELECTROLYSIS CELL COMPRISING: A. AN IMPERVIOUS JACKET PROVIDED WITH OPENINGS FOR INLET AND EGRESS OF ELECTROLYTE, FEED AND PRODUCT, B. A POROUS ELECTRODE PLATE OF DISHED CONFIGURATION TO HOLD A LEVEL OF ELECTROLYTE NOT EXCEEDING 6 INCHES IN DEPTH, SAID POROUS ELECTRODE PLATE BEING POSITIONED WITHIN SAID JACKET, MEANS DEFINING A FEED INLET PASSAGEWAY AT THE BOTTOM SURFACE OF SAID POROUS ELECTRODE TO PASS THE FEED INTO THE PORES OF SAID POROUS ELECTRODE, C. AN ELECTRODE PLATE SITUATED WITHIN THE DISHED CONFIGURATION OF THE DISHED ELECTRODE PLATE REMOVED FROM SAID DISHED ELECTRODE PLATE A DISTANCE NOT EXCEEDING 3 INCHES SO AS TO BE SUBMERGED IN THE ELECTROLYTE CONTAINED BY THE DISHED CONFIGURATION OF SAID POROUS ELECTRODE PLATE, AND D. TERMINALS FOR CONNECTING SAID ELECTRODE PLATES WITH AN ELECTRICAL SOURCE.
Claim 2
Dependent Claim
