Process for fabricating a cathode ray tube screen structure

Claim 1

IN A COLOR CATHODE RAY TUBE VIEWING PANEL HAVING A FIRST APERTURED SUBSTANTIALLY OPAQUE ELECTRICALLY CONDUCTIVE WEB BEING FORMED ON THE INNER SURFACE OF TH IEWING AREA OF THE PANEL A PROCESS FOR DISPOSING A SECOND APERTURED WEBBING OF A SECOND OPAQUE MATERIAL IN A CONTIGUOUS SUPERPOSED MANNER ON THE FIRST WEBBING SAID PROCESS COMPRISING THE STEPS OF: POSITIONING AN ELECTRODE MEMBER RELATIVE TO SAID PANEL IN SPATIAL RELATIONSHIP TO THE INNER SURFACE THEREOF AND SAID FIRST APERTURED CONDUCTIVE WEBBING THEREON, PLACING SAID PANEL IN SUPPORTIVE MEANS IN A TILTED MANNER TO ORIENT THE PANEL OPENING AND THE PANEL INNER SURFACE IN A SLANTED DOWNWARD DIRECTION, IMMERSING SAID PANEL AND ELECTRODE INTO AN ELECTROPHORETIC BATH IN A MANNER THAT BATH MAKES CONTACT WITH SAID CONDUCTIVE WEBBING AND SAID ELECTRODE MEMBER SAID BATH INCLUDING A SUSPENSION OF PARTICULATE SOLIDS INITIATING MOVEMENT OF SAID ELECTROPHORETIC BATH TO MAINTAIN A UNIFORMITY OF SUSPENSION AND EFFECT MOVEMENT OF SAID SUSPENSION RELATIVE TO SAID CONDUCTIVE WEBBING AND SAID ELECTRODE, APPLYING AN ELECTRICAL POTENTIAL BETWEEN SAID CONDUCTIVE WEBBING AND SAID ELECTRODE MEMBER FOR A TIME PERIOD TO EFFECT ELECTROPHORETIC DEPOSITION OF SAID PARTICULATE SOLIDS ON SAID FIRST APERTURED CONDUCTIVE WEBBING TO PROVIDE A DUO-WEBBING COMPRISING A SECOND APERTURED PROVIDE A CONTIGUOUSLY SUPERPOSED ON SAID FIRST WEBBING THE INNER DEFINING EDGE OF EACH WINDOW ENCOMPOASSMENT OF SAID SECOND WEBBING BEING SUBSTANTIALLY CONTIGUOUS WITH THE GLASS SURFACE OF SAID VIEWING PANEL EFFECTS A REDUCING OF THE SIZE OF SAID FIRST WEBBING APERTURES, REMOVING SAID PANEL FROM SAID ELECTROPHORETIC SUSPENSION, RINSING SAID PANEL AND DRYING SAID COATED WEBBING PREPARATORY TO THE SUBSEQUENT SCREENING OF PHOSPHOR ELEMENTS THEREON.
