Abstract: ABSTRACT OF THE DISCLOSURE                Method of preparing films of acrylonitrile polymer exhibiting very high tensile strength, stiffness, optical clarity, and outstanding gas barrier properties. Method en-tails extruding a hot, concentrated solution of said polymer in a solvent therefor that is water-soluble, e.g., dimethyl sulfoxide, onto a film-supporting surface, e.g., a flat surface, or a drum, which, preferably, has a low energy sur-face such as provided by wetting the surface with aqueous dimethyl sulfoxide, or coated with polytetrafluoroethylene, or other suitable means to thereby form a film. The resulting film is then contacted with as aqueous medium, e,g.,water to remove the solvent (e.g., dimethyl sulfoxide) and partially replace it with water, this treatment being effected under conditions that will prevent the film from curling or puckering. The resulting film is composed essentially of a???lonitrile polymer and water, and is ignition resistant. This film can be then biaxially stretched in a substantially non-drying environment at 100°C or less, preferably at 50-80°C followed by drying to remove the water, while maintaining the film under constained conditions to prevent or limit the degree of lateral and longitudinal shrinkage. The final film thus produced has a very high tensile strength and stiffness and very low gas permability.

Abstract: A GAS COMPRESSOR UNIT             Abstract of the Disclosure In the embodiment depicted, the unit comprises three, serially-coupled, multi-stage axial-flow gas compressors, having intercooling and demisting assem-blies interposed therebetween.  The compressor shafts are commonly coupled, in line, for powered drive from a single prime mover.  The intercooling and demisting assemblies are of exceptionally short axial length, define gas-entry areas of exceptionally large dimen-sion, and cause a pressure drop thereacross (i.e., across the intercoolers and demisters) not in excess of one p.s.i.  Each cooling assembly is only about one-third the total length of the compressor stages which deliver compressed gas thereinto, is fifteen to twenty-five times larger in area than a last-stage gas exit annulus, and constrains gas flow therethrough to unidirectional, axial conduct.
