Abstract: Disclosed is a composition for forming or treating reverse osmosis (RO), forward osmosis (FO), microfiltration (MF), or nanofiltration (NF) membranes, which includes a stable liquid blend of two of the following polymers: an oxygen polymer, a nitrogen polymer, and a sulfur polymer, where each polymer in a blend have matched solubility parameters; provided, that a nitrogen polymer can be in the form of a powder; where the weight ratio of polymers in each blend can range from 1:99 to 99:1; where each polymer optionally can be halogenated; where any polymer can be dispersed in a solvent for forming the blend.

Abstract: A method for making a collagen strengthened cellulosic sheet by providing a cellulosic pulp slurry; adding solubilized collagen to the pulp slurry, and mixing for a time effective for interaction of the cellulosic pulp slurry and solubilized collagen; forming the interacted cellulosic pulp slurry and solubilized collagen into a sheet; and drying the sheet; also, a method for using solubilized collagen for strengthening paper by mixing the solubilized collagen with a cellulosic pulp slurry; and making a cellulosic pulp product from the mixture and drying.

Abstract: A needleless valve (16), which may be housed in a plastic housing (12), has a web (18) provided with a slit (20) for blunt cannula access therethrough. The web (18) is provided with a lubricious coating (22) on at least a portion thereof, the coating (22) being polymeric and covalently bonded to the web (18). Coating (22) enhances the ease of use of valve (16) and increases its useful life by decreasing the deleterious effects of repeated cannula insertion and removal.

Abstract: A multilayer electric discharge recording material comprising an electrically anisotropic support layer disposed on one surface of a conductive layer and a transfer layer disposed on the other surface of the conductive layer. The transfer layer comprises a material that has a melting point between about 25.degree. and 150.degree. C. and that is capable of melting and adhering to a receiving medium such that a desired pattern or image can be formed and recorded on the receiving sheet.
