Claim 1
Independent Claim
121 words
A PROCESS FOR FILLING THE PORES OF A POROUS ELECTRICALLY CONDUCTIVE FRAME BODY COMPRISING SINTERED METAL POWDER OF A METAL SELECTED FROM THE GROUP CONSISTING OF NICKEL, IRON AND CADMIUM WITH NICKEL BYDROXIDE WHICH PROCESS COMPRISES THE STEPS OF IMMERSING SAID POROUS FRAME BODY AND AN ELECTRODE IN AN ELECTROLYTE BATH CONSISTING ESSENTIALLY OF AN ACIDIFIED AQUEOUS SOLUTION OF NICKEL NITRATE AND NITRIC ACID AND HAVING A PH OF ABOUT 3, CONNECTING SAID FRAME BODY CATHODICALLY AND CONNECTING SAID ELECTRODE ANODICALLY IN AN ELECTRIC CIRCUIT, AND PASSING ELECTRIC CURRENT WHILE MAINTAINING THE ELECTROLYTE BATH AT ABOUT THE INITIAL PH BY ADDITION OF ACID THERETO DURING SAID PASSAGE WHICH PREVENTS PRECIPITATION OF HYDROXIDE OF NICKEL WITHIN THE BULK OF THE ELECTROLYTE BATH.
Claim 2
Dependent Claim
