A process is described for preparing a stable aqueous emulsion of a polymer derived from an alkyl perfluoralkanoate and an alkylenimine, employing 2.5-10 percent (based on total solvent weight) of a water-miscible polymer solvent, and special emulsifiers. When fibrous cellulosic materials are treated with such emulsions using about from 1 to about 10 weight percent (based on the total emulsion weight) of the fluorinated ester, the resultant treated materials are rendered durably oleophobic and s...

A process for improving the bonding properties of high modulus graphite fibers is provided that comprises treating the fibers with a solution of sodium iodate in aqueous dioxane; washing and drying the treated fibers; contacting the treated fibers with a solution of tin tetrachloride in 2-butanone; and heating the fibers to remove the 2-butanone. An epoxy resin composite having a greatly improved interlaminar shear strength is obtained when the treated graphite fibers are employed as a reinforci...

An amusement ride device for a child or other person. The device including a rotatable outer tire and an inside hoop which is carried by roller bearing means within the tire, the hoop including a transverse handlebar, leg stretch bar against which a rider within the hoop may secure himself by bracing, the hoop remaining in a nonrotating position while the tire rotates during travel across the ground.

The cleaned surface of an aluminum or aluminum alloy product, for example, aluminum coil, is treated with a 0.5 to 3 second spray of a chromating bath heated to 40.degree. to 60.degree. C., said bath having a pH of 1.0 to 3.0 and containing 0.1 to 3.0 g/L of tungstate ions and/or molybdate ions, 0.5 to 4.0 g/L of hexavalent chromium ions, 5.0 to 30.0 g/L of phosphate ions, and 0.05 to 2.0 g/L of free fluoride ions. A highly corrosion-resistant, highly paint-adherent chromate coating can thereby ...

A textile having durability of maintaining water- and sufficient oil-repellency and soil releasability before and after cleaning can be obtained by a method of preparing a treated textile, having steps of: (1) preparing a treatment liquid containing a water- and oil-repellent agent, (2) adjusting pH of the treatment liquid to at most 7, preferably at most 3, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating...

Disclosed are compounds of Formula I: ##STR1## or a pharmaceutically acceptable salt or solvate thereof, wherein: R.sup.4 is alkenyl, alkoxy, or --OH. Also disclosed are pharmaceutical compositions containing compounds of Formula I, methods for inhibiting tumor necrosis factor-.alpha., and methods for treating septic shock, inflammation, or allergic disease.

A poromeric film is provided which is based on a polymer cement of polyurethane, polyvinyl chloride, and plasticizer. No internal non-solvent is used. The cement is applied to a water permeable substrate and coagulated in a water bath.

Excellent water repellency, Oil repellency, stain block property and yellowing-resistance are imparted to a textile by a method of preparing a treated textile has the steps of (1) preparing a treatment liquid containing a water- and oil-repellent agent and a stain blocking agent, (2) bringing a pH of the treatment liquid to at most 7, (3) applying the treatment liquid to the textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile. The trea...

A process for coating metal surfaces in which an uncured resin coating is formed on the surface of a metal by contacting the metal surface with an autodepositing coating composition that contains acid, oxidizing agent, and water-dispersible or water-soluble organic film-forming resin, and the uncured coating is thereafter dried, produces a strongly adherent, highly corrosion-resistant autodeposited coating when the uncured coating is brought, prior to its drying, into contact with an aqueous sol...

A chemically adsorbed monomolecular or a laminated monomolecular film comprising a monomolecular film formed on said substrate surface by covalent S-bonds is disclosed. For example, the covalent S-bond is selected of a group consisting of --(S.dbd.O)-- and --(O.dbd.S.dbd.O)--. A method of producing a chemical adsorption film comprising; contacting a substrate containing hydroxl groups present on the surface with a non-aqueous solvent containing a material having a thionyl halide group or sulfury...
