  • Patent number: 6736939
    Abstract: In a shoe press belt, in which the nip zone is narrower than the shoe width, the shearing force which normally acts on the belt at the outer boundary of the nip zone is made either weak or non-existent by forming the outer portions of the belt of less hardness than the inner, or central, portion of the belt, so that the less hard portions can be positioned directly opposite the outer boundaries of the nip zone. Alternatively, the outer portions of the belt can be made thinner than the central portion of the belt and the thinner portions positioned directly opposite to the nip zone boundaries. The shearing force applied to the belt at the nip ends of the roll is reduced or eliminated, cracking resulting from the shear force is reduced or avoided, and a belt having improved durability results.

    Abstract: The invented insulation is a ceramic fiber insulation wherein the ceramic fibers are treated with a coating which contains transition metal oxides. The invented process for coating the insulation is a process of applying the transition metal oxide coating to the fibers of the insulation after the fibers have been formed into a tile or other porous body. The coating of transition metal oxide lowers the transmittance of radiation through the insulation thereby lowering the temperature of the backface of the insulation and better protecting the structure that underlies the insulation.

The method enables reduction of the pore size of a porous inorganic membrane, such as metal oxides, metal carbides, metal nitrides and cermets. Mean pore diameters of below about 10 Å. Can readily and efficiently be achieved. After the conventional formation of an inorganic membrane, the pore size of the membrane is progressively reduced in a controlled manner to deposit one or more layers of an inorganic compound on the pore walls. This is done by exposing the membrane to the vapor of an inorganic precursor compound. The compound reacts with hydroxyl groups and or absorbed water molecules on the surface of the membrane and is thus bonded to the surface. Water vapor, oxygen, or vapors containing one or more oxygen ligands such as an alcohol are used to hydrolyze the deposited material to the inorganic membrane.

  • Patent number: 6592980
    Abstract: A process provides a ceramic film, such as a mesoporous silica film, on a substrate, such as a silicon wafer. The process includes preparing a film-forming fluid containing a ceramic precursor, a catalyst, a surfactant and a solvent, depositing the film-forming fluid on the substrate, and removing the solvent from the film-forming fluid on the substrate to produce the ceramic film on the substrate. The ceramic film has a dielectric constant below 2.3, a halide content of less than 1 ppm and a metal content of less than 500 ppm, making it useful for current and future microelectronics applications.

  • Publication number: 20030129378
    Abstract: A thermal barrier coating (TBC 26) and method for forming the TBC (26) on a component (10) characterized by a stabilized microstructure that resists grain growth, sintering and pore coarsening or coalescence during high temperature excursions. The TBC (26) contains elemental carbon and/or a carbon-containing gas that increase the amount of porosity (32) initially within the TBC (26) and form additional fine closed porosity (32) within the TBC (26) during subsequent exposures to high temperatures. A first method involves incorporating elemental carbon precipitates by evaporation into the TBC microstructure. A second method is to directly incorporate an insoluble gas, such as a carbon-containing gas, into an as-deposited TBC (26) and then partially sinter the TBC (26) to entrap the gas and produce fine stable porosity within the TBC (26).

  • Publication number: 20030104196
    Abstract: Silica-based refractories are impregnated with protective material that is more resistant towards attack by corrosive species. The protective material coats the surface of the refractory matrix and fills some of the cavity volume of its pores, crevices, surfaces imperfections and irregularities. The protective material is positioned by impregnating the refractory with a precursor which, under the input of energy, is converted into the corrosion resistant protective material.

  • Patent number: 6562444
    Abstract: A building material is provided in which fiber-cement is laminated to gypsum to form a single piece laminate composite. This single piece laminate composite exhibits improved fire resistance and surface abuse and impact resistance, but achieves these properties without the excessive weight and thickness of two piece systems. Additionally, because of the reduced thickness, the preferred laminate building material is easier to cut and is quicker and easier to install than two piece systems. Furthermore, forming the fiber-cement and gypsum into a single piece laminate eliminates the need to install two separate pieces of building material, thereby simplifying installation. In one embodiment, a ⅝″ thick laminate composite is provided in which a ½″ thick gypsum panel laminated to a ⅛″ thick fiber-cement sheet, the laminate composite having a fire resistance rating of 1 hour when measured in accordance with ASTM E119-98.
