Abstract
Abstract A method for coating metal anodes with electroconductive paint including the provision of a cylinder with a large enough volume of paint to coat an entire continuous surface of an anode, and delivering the paint from the cylinder to the anode at a constant and non-pulsating rate by the single displacement stroke of a piston in the cylinder.

Claim 1
Independent Claim
165 words
A METHOD OF COATING METAL ANODES WITH ELECTROCONDUCTIVE PAINT THE STEPS OF A. PROVIDING AN ELECTROSTATIC SPRAY GUM AT A HIGH ELECTRICAL POTENTIAL, B. PROVIDING A CYLINDER CONTAINING A PREDETERMINED VOLUME OF ELECTROCONDUCTIVE PAINT, SAID VOLUME OF PAINT IN SAID CYLINDER BEING LARGE TO COATED AN ENTIRE CONTINUOUS SURFACE OF A METAL ANODE TO BE COATED, C. PLACING A CONTINUOUS SURFACE OF A METAL ANODE TO BE COATED IN POSITION TO RECEIVE ELECTRONDUCTIVE PAINT FROM SAID SPRAY GUM, D. ENSURING THAT SAID METAL ANODE TO BE COATED IS AT GROUND POTENTIAL, E. POSITIVELY DELIVERING ELECTROCONDUCTIVE PAINT FROM SAID CYLINDER TO SAID SPRAY GUM AT A CONTINUOUS NON-PULSATING RATE BY THE SINGLE DISPLACEMENT STROKE OR A PISTON IN SAID CYLINDER, AND F. SPRAYING SAID DELIVERED ELECTROCONDUCTIVE PAINT FROM SAID SPRAY GUM ONTO SAID ANODE SURFACE AT SAID CONTINUOUS NON-PULSATING RATE THEREBY PROVIDING DELIVERY OF A SUFFICIENT VOLUME OF ELECTROCONDUCTIVE PAINT FROM SAID CYLINDER TO SAID CONTINUOUS METAL ANODE SURFACE TO COMPLETELY AND UNIFORMLY COAT SAID SURFACE.

Claim 3
Dependent Claim
36 words
A method as recited in claim 1 wherein said paint is delivered to said spray gun and is sprayed from said spray gun onto said anode at a constant rate of between 1 and 10 ml/minute.
Claim 4
Dependent Claim
16 words
A method as recited in claim 2 wherein said rate is between 1 and 5 ml/minute.
Claim 5
Dependent Claim
27 words
A method as recited in claim 1 comprising the further step of transversely moving said metal anode continuous surface to be coated relative to said spray gun.
Claim 6
Dependent Claim
24 words
A method as recited in claim 4 wherein said rate of movement of said anode with respect to said spray gun is 1 ft./minute.
Claim 7
Dependent Claim
64 words
A method as recited in claim 1 wherein the predetermined volume of paint in said cylinder is enough to coat a plurality of continuous anode surfaces during the single displacement stroke of said piston in said cylinder, and wherein said method comprises the further step of consecutively bringing a plurality of grounded metal anode continuous surfaces into position to receive paint from said gun.
Claim 8
Dependent Claim
77 words
A method as recited in claim 1 comprising the further steps of, after the volume of paint in said cylinder has been depleted, preventing delivery of paint from said cylinder to said spray gun, providing for communication between said cylinder and a paint reservoir, and withdrawing the piston in said cylinder and thereby simultaneously providing for the intake of another predetermined volume of electroconductive paint from said reservoir into said cylinder, whereby said method may be repeated.
Claim 9
Independent Claim
185 words
A method of coating metal anodes with electroconductive paint comprising the steps of a. providing a plurality of electrostatic spray guns at a high electrical potential, b. providing a plurality of cylinders, one associated with each of said spray guns and each containing a predetermined volume of electroconductive paint, the combination of said volumes of paint in said cylinders being large enough to coat an entire continuous surface of a metal anode to be coated, c. placing a continuous surface of a metal anode to be coated in position to receive paint from said spray guns, d. ensuring that said metal anode to be coated is at ground potential, e. positively delivering electroconductive paint from said cylinders to said spray guns at a continuous nonpulsating rate by the single displacement stroke of a piston in each of said cylinders, and f. spraying said delivered electroconductive paint from said spray guns onto said anode surface at said continuous non-pulsating rate thereby providing delivery of a sufficient volume of electroconductive paint from said cylinders to said continuous metal anode surface to completely and uniformly coat said surface.
Claim 10
Independent Claim
185 words
A method of coating metal anodes with electroconductive paint comprising the steps of a. providing a plurality of electrostatic spray guns at a high electrical potential, b. providing a plurality of cylinders, one associated with each of said spray guns and each containing a predetermined volume of electroconductive paint, the combination of said volumes of paint in said cylinders being large enough to coat an entire continuous surface of a metal anode to be coated, c. placing a continuous surface of a metal anode to be coated in position to receive paint from said spray guns, d. ensuring that said metal anode to be coated is at ground potential, e. positively delivering electroconductive paint from said cylinders to said spray guns at a continuous nonpulsating rate by the single displacement stroke of a piston in each of said cylinders, and f. spraying said delivered electroconductive paint from said spray guns onto said anode surface at said continuous non-pulsating rate thereby providing delivery of a sufficient volume of electroconductive paint from said cylinders to said continuous metal anode surface to completely and uniformly coat said surface.
