Abstract: 1,081,048. Reverse osmosis. GENERAL DYNAMICS CORPORATION. Dec. 15, 1965 [Dec. 21, 1964], No. 53204/65. Heading B1X. Water is recovered by reverse osmosis from an aqueous solution, e.g. pure water from sea water, by supplying the aqueous solution to the outside of an envelope 16, which consists of two semi permeable membranes 18 and 20 sealed together around three edges with a porous backing material 24 disposed therebetween, at a pressure greater than its osmotic pressure and removing water from the porous backing material. The envelope may be spirally wound with a separator grid 17 around a hollow mandrel 15, with spaced holes 32 of the mandrel disposed adjacent the backing material at the unsealed edge of the envelope (see Fig. 3). This spirally wound envelope when enclosed in a pressure tight casing forms a unit, a plurality of such units fed through their inlet pipes 42 from a header forming a plant. The casing has an outlet 44 for waste aqueous solution and has a take off assembly 12 which communicates with the mandrel interior and with take-off tubes 70 (Fig. 4) which may be embedded in the backing material. The necessary pressure is obained by a pump in the inlet and valves in the outlet. The membranes are fabricated of a polymeric material with the backing material of cotton or wool felt and the casing of copper or another corrosion resistant material such as polyvinyl chloride.

Title: Method for Making Continuous Filament-like Products from Films
IPC: D01D5/42
Filed: 1966-12-02
Abstract: 1,161,568. Making filaments from films. BARMAG BARMER MASCHINENFABRIK A.G. 2 Dec., 1966 [23 July, 1965], No. 54084/66. Heading B5B. In a method for making continuous filamentlike products from thermoplastic polymeric material in which a film web of the thermoplastic polymeric material is cut longitudinally into strips, the strips are stretched longitudinally to a multiple of their original length, and are subsequently wound on to bobbin tubes, each strip of stretched film is, before being wound, caused to travel through an open guide whereby it is condensed by transverse compression in the guide into a filament-like form having a compact, substantially elliptical or rounded cross-section as it approaches a speed of travel corresponding to the winding speed. The film strips may be set in condensed form by the action of heat. The strip of film which, initially, is guided flat may be guided edgewise under tension over a fixed or rotating optionally heated guide or deflecting means arranged transversely of the direction in which the strip is travelling so that the strip is condensed by compressive force acting across the strip. The guide means may comprise two rotatable guide rollers spaced slightly apart to cross one another transversely of the direction in which the strip is travelling, the strip being thereby condensed by the velocity components of the guide rollers directed across the strip towards its centre. The condensed strips are wound to form cross-wound packages or elongated caplike packages of any desired layer structure on winding devices whose rotational speed is governed by the particular tension of the strip.
