Claim 1
Independent Claim
132 words
THE METHOD OF SIMULATING BARREL PLATING OPERATION FOR LABORATORY EVALUATION COMPRISING SUSPENDING AN ANODE IN AN ELECTROLYTE; ROTATING A CATHODE IN SAID ELECTROLYTE AT A DISTANCE LATERALLY SPACED FROM SAID ANODE, SAID CATHODE CONSISTING OF A METALLIC MEMBER HAVING A CENTRALLY DISPOSED BASE PORTION AND A PAIR OF SPACED LEG PORTIONS PROJECTING LATERALLY THEREFROM TO DEFINE A RECESS THEREBETWEEN, SAID BASE PORTION EXTENDING IN SUBSTANTIALLY VERTICAL RELATIONSHIP AND EACH OF SAID LEG PORTIONS EXTENDING IN A SUBSTANTIALLY VERTICAL PLANE AND HAVING ITS OUTER FREE EDGE EXTENDING SUBSTANTIALLY VERTICALLY AND SUBSTANTIALLY RECTILINEARLY; AND SUPPLYING CURRENT TO SAID ANODE AND ROTATING CATHODE TO PRODUCE CURRENT FLOW THROUGH SAID ELECTROLYTE WITH VARIATION IN THE CURRENT DENSITY ALONG THE SURFACE OF SAID CATHODE LEG PORTIONS INWARDLY OF THE OUTER FREE EDGES AND TOWARDS SAID BASE PORTION.
