Method of electrocoating with variation of electrical inducement

Claim 1

IN A CONTINUOUS METHOD OF COATING WHICH COMPRISES PASSING ELECTRICALLY CONDUCTIVE OBJECTS THROUGH A LIQUID COATING BATH HAVING AN ORGANIC COATING MATERIAL DISPERSED THEREIN AND A FIRST ELECTRODE IN ELECTRICAL COMMUNICATION THEREWITH, EACH OF SAID OBJECTS WHILE PASSING THROUGH SAID BATH SERVING AS A SECOND ELECTRODE, AND PROVIDING A DIRECT CURRENT FLOW OF ELECTRICAL ENERGY THROUGH SAID BATH AND BETWEEN SAID FIRST ELECTRODE AND SAID SECOND ELECTRODE THEREBY ELECTRICALL INDUCING DEPOSITION OF SAID COATING MATERIAL UPON SAID SECOND ELECRODE, THE IMPROVEMENT WHICH COMPRISES PASSING SAID SECOND ELECTRODE THROUGH A ZONE OF PREDETERMINED ELECTRICAL INDUCEMENT TO COATING AS MEASURED BY THE CURRENT DENSITY UPON AN UNCOATED ELECTRODE AND THENCE INTO A ZONE OF GREATER ELECTRICAL INDUCEMENT TO COATING AS MEASURED BY THE CURRENT DENSITY UPON AN UNCOATED ELECTRODE BEFORE REMOVING SAID SECOND ELECTRODE FROM SAID BATH.
