Title: Air-cooled condenser
IPC: F28B9/00
Filed: 1963-03-27
Abstract: 978,067. Condensing vapours ; power plant. HAPPEL G.m.b.H., [trading as GEA LUFTKUEHLERGESELLSCHAFT HAPPEL G.m.b.H. & CO. KOMM.-GES.]. March 27, 1963 [March 31, 1962], No. 12175/63. Heading B1B. In an air-cooled condenser system comprising a group of downflow condenser elements 4 connected in parallel, and a group of reflux condenser elements 11 connected in parallel, the vapour-to-be-condensed is supplied to the two groups from pipe 3 via distributing pipes 5 and 12 respectively, a valve 6 being provided in pipe 5 so that the downflow elements can be shut off from pipe 3. The condenser elements may take the form of parallel-spaced, finned tubes, each group of elements having a separate fan for blowing cooling air over the outside surfaces of the tubes. The system is suitable for the condensation of steam from turbine 2 ; for in cold weather only the reflux elements are kept in operation, thus obviating the risk of ice-formation. A partial vacuum is applied by pump 9 and pipe 8 at the lower ends of the downflow elements and at the upper ends of the reflux elements. The condensate is collected, via pipes 7 and 13, in tank 14 which has an overflow pipe 15 leading to tank 16. A pressure-equalization pipe 19 extends between pipe 3 and tank 16. Tank 14 can be connected to either pipe 19 or to vacuum pump 9 via pipes 18 and 17, respectively. A pump 22 is connected to tank 16 to supply the condensate via a degasifier to the feed tank of the turbine. Specification 900,407 is referred to.

Title: Processes for rendering textiles water-repellent and products therefrom
IPC: D06M15/61
Filed: 1936-05-01
Abstract: Cellulose or cellulose derivative-containing textile materials, or wool, in the form of fibres, yarns or woven materials are rendered water-repellant by superficial reaction with isocyanates containing an alkyl, cycloalkyl or aralkyl residue with a saturated alkyl residue of at least 10 carbon atoms or a saturated or unsaturated residue of an alcohol of the sterol group.  The isocyanates may be of the general formula R.CO.N.CO, and may contain the atoms or groups O, S, N, COO, OCO, NR, CONR, NRCO, SO2, NRSO2, SO2NR when R represents hydrogen or a hydrocarbon radical.  Fatty acid azides may also be employed. The textile is passed through a solution of the isocyanate in a suitable solvent and thereafter subjected to a temperature of above 100 DEG  C. for several minutes.  Cellulose or cellulose derivative fibres may be treated immediately after spinning, or the isocyanate may be added to a cellulose acetate spinning solution.  In examples: (1) a printed cr<\>zepe, having a de-lustered viscose rayon warp and viscose cr<\>zepe weft, is treated with a solution of octadecylisocyanate and heated, first to 100 DEG  C. and then to 140 DEG  C.; (2) acetate satin having acetate satin warp and viscose cr<\>zepe weft is sprayed with a solution of dodecylisocyanate and heated to 130 DEG  C.; (3) cuprammonium silk is immersed in a solution of eicosylisocyanate and heated to 150 DEG  C.; (4) octadecylisocyanate is added to a spinning solution of cellulose acetate in acetone; (5) cotton fabric is treated with a solution of heptacosylisocyanate and heated to 150 DEG  C.; (6) a viscose rayon fabric is treated with a solution of 1-stearyl oxyphenylene-4 isocyanate and further treated as in (1); (7) wool muslin is treated with a solution of cholesterol adipic acid ester azide and heated to 140 DEG  C.; and (8) worsted fabric is treated with octacosane acid azide and heated to 140 DEG  C.  Cholesterol adipic acid ester azide is prepared by reacting cholesterol with adipic acid dichloride to form the semi-ester acid chloride and then reacting this with sodium azide.
