    摘要： The present invention is directed to apparatus and methods for effectively supplying, feeding, measuring, proportioning, mixing, pressurizing, and heating on a semi-continuous basis, a plurality of fluids. Preferably, the fluids comprise at least one substantially non-compressible fluid, such as coating formulation, and at least one substantially compressible fluid, such as carbon dioxide, to form a substantially accurately proportionated coating admixture in the supercritical state of the compressible fluid for spraying the combined mixture through a spraying means onto a substrate to produce a coating. The process employs vessels having a known displacement volume to feed and proportion the fluids. The pressurization, mixing and heating is accomplished in an oscillation loop wherein the mixture is pressurized and heated while in such oscillation loop. A spray gun connected to the oscillation loop is used to spray the mixture.

    摘要： Methods and apparatus are disclosed for forming a liquid spray mixture containing accurately proportionated amounts of viscous coating concentrate and compressed fluid diluent such as carbon dioxide. The proportionation is accomplished by passing the fluid diluent through two sets of flow restrictors under the same pressure drops to form two proportioned flows of diluent. One diluent flow is converted by volumetric displacement to an equal flow of liquid concentrate, which is mixed with the other diluent flow to form the liquid spray mixture.
