design and development of a 5,000 barrel collapsible fabric petroleum fuel tank assembly

ilc dover, after developing two leading candidate coated fabrics for use on the 5,000 barrel collapsible fabric fuel tank, designed and fabricated that fuel tank for testing in the tropics. the tank was built from the polyurethane coated kevlar fabric. ilc designed high stress compression rings and a wick-proff suction stub for use on the..

plastic foam coating: processes, formulations, and applications 1975-july, 1982 (citations from the rubber and plastics research association data base)

this bibliography contains citations concerning foam coating technology. equipment and processes for applying foam coatings for such applications as packaging, roof construction, foam lined fabrics, marine structures, and automobile parts are examined. latex, urethane, and vinyl foams are emphasized for such considerations as corrosion re..

carcinogenesis bioassay of c.i. disperse yellow 3 (cas no 2832-40-8) in f344 rats and b6c3f1 mice (feed study)

a carcinogenesis bioassay of c.i. disperse yellow 3 (87.6 dye), a textile dye, was conducted by feeding diets containing 5,000 or 10, 000 ppm of the test substance to groups of 50 f344 rats of either sex for 103 weeks. similar groups of 50 b6c3f1 mice received diets containing 2,500 or 5,000 ppm of the test substance for 103 weeks groups ..

an investigation of the effects of cavitating water jets on the surface preparation of structural steel prior to repainting

environmental constraints on the emission of particulate matter into the air during abrasive blast cleaning of steel structures prompted an investigation in to the use of cavitating water jets to propare surfaces prior to repainting. several cavitating water jet nozzles were lab tested to determine their area cleaning rate, effectiveness ..

surface treatment of glass substrates for the preparation of long-lived carbon stripper foils

glass substrates having uniformly distributed microscopic grains on the surfaces are useful for making long-lived carbon stripper foils for heavy ions. a method of surface treatment of glass substrates to form the surface structure is described. this method consists of precipitation of glass components, such as soda, onto the surfaces in ..

effect of several surface treatments on the strength of a glass ceramic-to-metal seal

test shells of inconel 625, inconel 718, 21-6-9 stainless steel, and hastelloy, c-276 were plasma and/or chemically cleaned before sealing with a multi-component glass-ceramic-to-metal seal was evaluated using a hydrostatic burst test. the results show that plasma cleaning can be used to increase the hydrostatic burst strength and hermeti..
