Abstract: Process and apparatus adds counterions into the aqueous solution of an electrode chamber of an electrolytic desalination or demineralization unit. In the demineralization unit, oppositely charged ions are electrolytically generated within electrode chambers and defused into the stream of aqueous solution to be demineralized. In their migration in response to the application of an electric potential, the ion streams are subjected to displacement steps in cation and anion exchange masses separated by selectively permeable ion exchange membranes. A counterion-containing liquid is subjected to an electrical voltage field, separate or in conjunction with the desalination unit, and the counterions to be added are passed through a selectively permeable ion exchange membrane into the respective electrode chamber of chambers of the desalination unit.

Abstract: A method of making contact lens materials which are identifiable from similar contact lens materials. This is done by selecting a fluorescent colored soluble organic fluorescent dye in solid state solution in a transparent organic resin. The fluorescent color pigment is added in small amounts ranging from 0.0003 to 0.009 parts by weight of the lens monomer mixture. The lens monomer mixture containing the fluorescent dye is polymerized to form a solid contact blank. A contact lens is made from the solid polymerized blank containing the colored fluorescent dye. The contact lens convex surface is placed on a dark flat surface. In the absence of visible light the lens is irradiated with ultraviolet light. The colored fluorescent light emanating from the dye within the lens is concentrated at the lens edge by reflecting between the lens polished optical surfaces. The colored fluorescent light exits the lens at the edge. The lens material is identified by observing the color visible at the lens edge.
