Abstract: THE APPARATUS INCLUDES A STORAGE TANK FOR SOLVENTS, A BALL MILL, AND A TINTING TANK. CARBON DIOXIDE SUPPLY LINES ARE CONNECTED TO EACH OF THESE. ADDITION OF CARBON DIOXIDE UNDER PRESSURE TO THE STORAGE TANK PRECARBONATES THE ORGANIC SOLVENT AND PROVIDES A CARBONATED PRODUCT WHEN MILLED WITH A PIGMENT. THE CARBON DIOXIDE CAN BE ADDED AT THE MILL EITHER ALONE, OR IN COMBINATION WITH PRECARBONATION. SOLVENTS OR DILUENTS ARE ADDED IN THE TINTING TANK AND THE RESULTING PRODUCT IS A CARBONATED PAINT OR INK WHICH HAS IMPROVED ANTI-SKINNING CARACTERISTICS. THE STORAGE TANK ARRANGEMENT REDUCES EMISSIONS OF ORGANIC SOLVENTS INTO THE ATMOSPHERE. THE USE OF CARBON DIOXIDE REDUCES FLAMMABILITY IN THE SYSTEM, OF THE PRODUCT, AND DURING SUBSEQUENT USE. IMPROVED CONDUCTIVITY OF THE CARBONATED SOLVENT ALSO RESULTS.

Abstract: Enclosed paint tanks are maintained substantially free of pain residue by heating liquid thinner to vaporize the same, conducting the vapor to the head space of the tank, and causing the vapor to condense on the inside of the tank so that the liquid thinner rinses the side walls and keeps them clean. When the thinner is flammable, an inert gas is fed into the head space to maintain an inert protective atmosphere therein. The disclosed apparatus includes a pair of large, enclosed storage tanks each having an impeller and a common paint supply line. Conduits interconnect the tanks and a pump is provided for discharging the paint from either tank. The lowermost conduit has a storage chamber at either end and a ball is propelled between the chambers to loosen residue in the conduit. At the top of the tanks is a container for the liquid thinner. A float in the container maintains the level of the liquid thinner. A float in the container maintains the level of the liquid thinner. A heating element in the container is adapted to vaporize the thinner. Conduits lead from the container to the tanks to feed the vapor thereto.
