Abstract
1,173,179. Semi-permeable membrane; gas diffusion membrane. S. RUBENS. 29 Sept., 1967, No. 44370/67. Headings B1L and B1X. [Also in Divisions C7 and G2] Microperforated stainless steel sheet produced electrolytically (see Division C6-7) is impregnated with microporous-membrane-producing material to provide an element for use in dialysis or gaseous diffusion. Examples of such materials are polystyrene, co-polymers of polyvinylchloride and acrylonitrile, silicones, polyvinyl alcohol, cellulose esters and gelatine. Inorganic materials may also be used, for example, sodium silicate solutions, in which case the dried, treated sheet is subjected to acid to dissolve out the sodium and leave a microporous insoluble silica membrane. Thin fluorocarbon coatings may also be used to form permeable membranes.
