  • Patent number: 5989638
    Abstract: The invention is directed to a method and apparatus for coating substrates by a liquid spray so as to avoid entrapment of gaseous bubbles, particularly air bubbles, in the coating and desirably to thereby obtain bubble-free coatings. More particularly, the invention involves spray applying the coating to a substrate in an atmosphere consisting of gases having appreciable solubility in the applied coating, such as carbon dioxide, such that gas bubbles that may become entrapped in the coating are removed after application by the gases dissolving into the coating and diffusing to the surface.

  • Patent number: 5370812
    Abstract: Lubricant compositions are disclosed which comprise polyalkylene glycols and hydrocarbon solvents having 15 or less carbon atoms per molecule. The polyalkylene glycols are soluble in fluorocarbon-based refrigerants, such as for example, HFC-134a, and the hydrocarbon solvents are soluble in the polyalkylene glycols. Thus, the lubricant compositions are particularly well suited as lubricants in refrigeration systems, such as for example, automobile air conditioners, which contain fluorocarbon-based refrigerants. Refrigerant/lubricant compositions comprising refrigerants and the lubricant compositions are also disclosed.
