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.
