Abstract: A method and apparatus for batch tinting paint by adding preselected amounts of selected paint colorants to a batch of base paint in a paint vessel at a mixing station. The different paint colorants are stored at a colorant storage station, and a charge of paint colorant consisting of preselected amounts of one or more selected paint colorants to be used in tinting a batch of base paint are delivered to the inlet end of a single tube delivery line extending from the storage station to the mixing station. The charge of paint colorant is thereafter purged from the line and delivered to the mixing vessel by passing a purging fluid including a purging liquid compatible with the colorant into the line while delivering the purging liquid and colorant to the mixing vessel.

Abstract: An outwardly extending discharge line is pivotally connected to a supply line. A torsion spring unit urges the discharge line from a lower dispensing position to a raised position. Apparatus is provided for automatically opening and closing a valve in the supply line in response to movement of the discharge line between its positions. An outlet valve is provided at the outlet of the discharge line and is opened and closed by a pneumatic cylinder controlled by movement of a scale. The outlet valve is a balltype valve having a valve insert with openings of a size such that surface tension of the fluent material will prevent dripping. The insert is formed of a bearing material and is adjustable against the ball valve element to accommodate any wear.

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 characteristics. 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. A container has a carbonated paint or ink therein and the carbon dioxide is interstitially spaced in an amount sufficient to evolve into the head space of the container to provide a protective atmosphere. The printing method includes placing carbonated ink in a gravure press fountain, and supplying the carbonated ink to the gravure roll which applies it with direct pressure to the paper. The carbon dioxide is interstitially spaced in the ink in an amount in excess of one volume per volume which reduces the static electricity charge on the rolls, evolves a protective carbon dioxide blanket in the fountain, and reduces fire hazard.

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.
