Multi-purpose electrode for electrochemical processes

Claim 1

A MULTI-PURPOSE ELECTRODE FOR ELECTRO-CHEMICAL PROCESSES, WHICH COMPRISES A POROUS ELECTRODE CORE CONSISTING OF A SOLID MASS OF AGGLOMERATED CONDUCTIVE PARTICLES AND OF SUBSTANTIALLY UNIFORM DENSITY THROUGHOUT AND PROVIDED WITH A FIRMLY ADHERENT POROUS COATING WHICH CONSISTS OF CONDUCTIVE PARTICLES, THE COATING HAVING PORES THE MEAN DIAMETERS OF WHICH ARE LESS THAN THE MEAN DIAMETERS OF THE INTERSTICES BETWESEN THE PARTICLES FORMING THE CORE, THE CORE BEING FORMED WITH SEPARATE SPACED DUCTS WHICH TERMINATE WITHIN THE BODY OF THE CORE, AND MEANS FOR SUPPLYING FLUID TO ONE DUCT TO CAUSE IT TO PERMEATE THE MATERIAL OF THE ELECTRODE AND FOR WITHDRAWING FLUID FROM THE OTHER DUCT WHEREBY ALL OF THE FLUID PASSES THROUGH THE MATERIAL OF THE CORE, THE PORES IN THE COVERING BEING OF SUCH SIZE AS TO BLOCK THE ESCAPE OF GAS INTO THE ELECTRLYTE WITHOUT JPREVENTING THE PENETRATRATION OF THE ELECTROLYTE INTO THE CORE.
