  • Apparatus for cleaning objects with volatile solvents
    Patent number: 5113883
    Abstract: A method for maintaining a flammable solvent in a nonflammable environment involves covering the flammable solvent with a nonflammable vapor blanket provided by a nonflammable solvent, such that vapors from the flammable and nonflammable solvents form a nonflammable gaseous mixture in the blanket. Such a method is used in removal of both oil-based and polar contaminants to control the flammability potential of an alcohol solvent. An apparatus for cleaning articles using fluorocarbon and alcohol solvents includes a chamber having a plurality of compartments for containing the solvents and a bounded vapor space. At least one of the compartments contains liquid fluorocarbon and at least one other will contain liquid alcohol. The solvents voltalize into the bounded vapor space to provide a nonflammable vapor blanket over the alcohol-containing compartment.
    Type: Grant

  • Washing of semipermeable membrane
    Patent number: 4767538
    Abstract: A method of preparing a dialyzer unit having a plurality of coextending hollow fibers includes washing interior fiber surfaces with an acetic acid both, flushing the interior surfaces with an aqueous glycerin solution, and removing the residual water while retaining a substantial quantity of absorbed glycerin in the fibers. The dialyzer can then be sealed and sterilized.
