  • Patent number: 5955140
    Abstract: This invention has enabled a new, simple thin film nanoporous dielectric fabrication method. In general, this invention uses glycerol, or another low volatility compound, as a solvent. This new method allows thin film aerogels/low density xerogels to be made without supercritical drying, freeze drying, or a surface modification step before drying. Thus, this invention allows production of nanoporous dielectrics at room temperature and atmospheric pressure, without a separate surface modification step. Although this new method allows fabrication of aerogels without substantial pore collapse during drying, there may be some permanent shrinkage during aging and/or drying. This invention allows controlled porosity thin film nanoporous aerogels to be deposited, gelled, aged, and dried without atmospheric controls.

    Abstract: Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier substrate such as tissue paper web and a emulsion applied to the substrate, wherein the emulsion comprises a continuous external lipid phase and a dispersed internal polar phase (e.g., water). The continuous external lipid phase of this emulsion is sufficiently brittle that it ruptures when subjected to low shear during use to release the dispersed internal polar phase.

  • Patent number: 5948475
    Abstract: A process for providing elemental metals or metal oxides distributed on a carbon substrate or self-supported utilizing graphite oxide as a percursor. The graphite oxide is exposed to one or more metal chlorides to form an intermediary product comprising carbon, metal, chloride, and oxygen. This intermediary product can be further processed by direct exposure to carbonate solutions to form a second intermediary product comprising carbon, metal carbonate, and oxygen. Either intermediary product may be further processed: a) in air to produce metal oxide; b) in an inert environment to produce metal oxide on carbon substrate; c) in a reducing environment to produce elemental metal distributed on carbon substrate. The product generally takes the shape of the carbon precursor.

  • Patent number: 5948472
    Abstract: A torsion box, useful for skis, snowboards or the like, has a constant cross section and a hollow interior. The torsion box is made from a plurality of plies and a resin matrix, at least some of the plies consisting of fibers disposed at an angle with respect to a longitudinal axis of the torsion box. The plies include fibers preferably selected from the group consisting of glass, carbon and Kevlar.RTM.. Particularly, the fibers will be angled with respect to the longitudinal axis of the torsion box within a range of about 0.degree. to about 45.degree.. The torsion box may be made by a pultrusion process where the desired fibers are pulled through a resin bath, or injected with resin, and heated in a die, then cut to a desired length. The plies are arranged to impart a material imbalance to the torsion box so that, upon cooldown, the product exhibits a predetermined camber.

  • Patent number: 5939197
    Abstract: A surface treatment, especially for titanium and aluminum alloys, forms a sol-gel film covalently bonded on the metal surface to produce strong, durable adhesive bonds between the metal and an organic adhesive without using toxic chemicals and while significantly reducing or eliminating rinse water requirements of traditional anodizing or etching processes. An aqueous sol containing an zirconium and an organosilane with an organic acid catalyst and zirconium stabilizer is applied to etched or grit blasted substrates by dipping, spraying, or drenching, to produce bonds in a single application comparable in strength and performance to standard anodize controls. Parameters affecting performance include the sol composition, the Si/Zr ratio, the ratio of sol ingredients, the concentration of the sol, the carrier solvent, solution age, catalysts, surface pretreatment, application method, curing process, and primer used.

  • Patent number: 5939201
    Abstract: The subject of the invention is a process for depositing, especially continuously, on a glass ribbon (10) of a float line, a reflective layer (3) based on a metal whose melting point is less than or equal to the temperature at which the glass ribbon acquires dimensional stability. The deposition is carried out in a controlled atmosphere, this being inert or reducing, when the glass ribbon (10) has already acquired its dimensional stability, by bringing the surface of the said ribbon into contact with the metal (22) in pulverulent form or in molten form, the temperature of the ribbon during contacting being chosen so that the powder melts and coalesces, or so that the molten metal forms a sheet, at the surface of the ribbon, leaving a solid continuous layer when the temperature of the ribbon is at a temperature of less than or equal to the melting point of the metal.

  • Patent number: 5939194
    Abstract: A method for highly hydrophilifying the surface of an article by photoexcitation of a semiconductor photocatalyst and maintaining the hydrophilicity is disclosed. A layer containing a photocatalyst is formed on a substrate. Onto the surface of the layer are fixed a hydroxyl group upon photoexcitation of the photocatalyst and a physically adsorbed water molecule in the vicinity of the hydroxyl group upon photoexcitation of the photocatalyst. Thus, the surface is highly hydrophilified. Further, this surface, simultaneously with the hydrophilification, exhibits higher hydrophobicity.
