    摘要: A method of precipitating colloidal materials from aqueous systems and a dynamic bimetallic galvanic cell is disclosed, said cell including a metallic electrode which provides a source of flocculating agent and an inert electrode to which the metallic electrode is short circuited. When water containing colloidal particles is passed through the galvanic cell and the electrodes are short circuited, the metallic electrode provides a source of flocculating agent which coprecipitates with the colloidal particles, forming a sediment which can be readily removed. The cell is constructed to maximize the contact between the water and the electrode surfaces and to maintain the metallic electrode short circuited against the inert electrode as the metallic electrode is consumed.

    摘要: A semipermeable composite membrane is prepared by glow discharge polymerization of a combination of an organic monomer and an inorganic monomer in the presence of a porous support, the polymerization resulting in deposition of a thin film of copolymer on the surface of the support.

    摘要: A soft corneal contact lens comprising a soft, highly oxygen-permeable, polymeric lens having formed on the surface thereof an ultrathin, optically clear, impermeable barrier coating. The barrier coating is tightly cross-linked and comprises the reaction product resulting from an electrical glow discharge polymerization process conducted in a gaseous atmosphere and will prevent diffusion into the lens of lipids and other large molecules from the eye's tear film. The lens is formed from silicone or polyurethane. The gaseous atmosphere consists essentially of compounds selected from the group consisting of hydrocarbons; halogenated hydrocarbons; halogenated hydrocarbons and hydrogen; hydrocarbons and a halogen; and a mixture of any two or more of these compounds. The surface of the fully formed lens is highly hydrophilic which is accomplished during the polymerization process or in an additional step comprising glow discharge in the presence of oxygen or argon.
