  • Patent number: 6582555
    Abstract: The present invention is a method for uniformly applying a foam to a wet tissue web is provided. Specifically, a foam is first formed from a liquid-based composition and a gas, such as air. Once formed, the foam is applied by a foam applicator to the wet tissue web. In one embodiment, for example, the foam applicator applies the foam with a flexible scraper contacting the wet tissue web during the application of the foam. When applied with the foam, the wet tissue web typically has a solids consistency less than about 95% by dry weight of the tissue web. In some embodiments, one or more vacuum slots may be utilized in conjunction with the foam applicator to facilitate uniform application of the foam to the wet tissue web.

  • Patent number: 6572642
    Abstract: A prosthesis having an apertured structure is located in a chamber (11) which is taken to sub-atmospheric pressure. Once sub-atmospheric pressure has been reached, a liquid, optionally containing pharmacological agents, is introduced into the chamber. Drawn by the sub-atmospheric pressure, the liquid saturates the apertured structure of the prosthesis. In this way, the invention eliminates the risk of air being trapped in the apertured structure that could give rise to the formation of blood clots after implantation of the prosthesis. The liquid can contain drugs that penetrate the prosthesis, performing their therapeutic action locally and over time after implantation.

  • Publication number: 20030100691
    Abstract: The present invention pertains to a processing method to produce a porous polymer film that consists of sp2C—X and HC-sp3C&agr;—X bonds (wherein, X═H or F), and exhibits at least a crystal melting temperature, (“Tm”). The porous polymer films produced by this invention are useful for fabricating future integrated circuits (“IC's”). The method described herein is useful for preparing the porous polymer films by polymerizing reactive intermediates, formed from a first-precursor, with a low feed rate and at temperatures equal to or below a melting temperature of intermediate (T1m). Second-precursors that do not become reactive intermediates or have an incomplete conversion to reactive intermediates are also transported to a deposition chamber and become an inclusion of the deposited film. By utilizing a subsequent in-situ, post treatment process the inclusions in the deposited film can be removed to leave micro-pores in the resultant film.

    Abstract: The present invention is useful in growing complex films with high quality (low lattice strain, large grain size, high degree of perfection) at high rates and large area, and high efficiency use of material. A solid-state film is grown from a liquid, where atoms are supplied continuously by vapor deposition onto the liquid surface. The desired film material grows from or is precipitated from the liquid flux, which is in thermodynamic equilibrium with the desired film. The desired film growth starts at a substrate interface. If this is a biaxial textured surface suitable in chemical reactivity and lattice constant, the growth will be epitaxial with the substrate. The atomic mixture that forms the deposited film is supplied by the arrival of the atoms from a vapor onto the surface of the liquid flux. An important additional factor in the case of an oxide such as the HTSC YBCO is that activated oxygen needs to be present, along with molecular oxygen.

  • Publication number: 20030008068
    Abstract: A process for making high aspect ratio metal flakes comprises applying a multi-layer sandwich of vapor deposited metal and release coats in alternating layers to a rotating chilled drum or suitable carrier medium contained in a vapor deposition chamber. The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent-soluble materials applied by suitable coating or vapor deposition sources contained in the vapor deposition chamber. The release coat materials can be a thermoplastic solvent-soluble polymer. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free.

  • Patent number: 6503572
    Abstract: Improved silicon carbide composites made by an infiltration process feature a metal phase in addition to any residual silicon phase. Not only are properties such as mechanical toughness improved, but the infiltrant can be so engineered as to have much diminished amounts of expansion upon solidification, thereby enhancing net-shape-making capabilities. Further, multi-component infiltrant materials may have a lower liquidus temperature than pure silicon, thereby providing the practitioner greater control over the infiltration process. In particular, the infiltration may be conducted at the lower temperatures, where low-cost but effective bedding or barrier materials can terminate the infiltration process once the infiltrant has migrated through the permeable mass up to the boundary between the mass and the bedding material.

  • Publication number: 20030003232
    Abstract: A catalyst composition is applied to an interior of a hollow substrate. The composition is coated on the substrate by immersing the substrate into a vessel containing a bath of coating slurry. A vacuum is then applied to the partially immersed substrate. The intensity of the vacuum and its application time is sufficient to draw the coating slurry upwardly from the bath into each of a plurality of channels located in the interior of the hollow substrate. After removing the substrate from the bath it is rotated 180°. A blast of pressurized air is applied at an intensity and for a time sufficient to distribute the coating slurry within the channels of the substrate to form a uniform coating profile therein.

  • Patent number: 6479095
    Abstract: A high-pressure vessel is allowed to be in an initial state, and a first chamber is disposed downward. Copper or copper alloy is placed in the first chamber, and SiC is set in a second chamber. The high-pressure vessel is tightly sealed, and then the inside of the high-pressure vessel is subjected to vacuum suction through a suction pipe. An electric power is applied to a heater to heat and melt the copper or copper alloy in the first chamber. At a stage at which the molten copper in the first chamber arrives at a predetermined temperature, the high-pressure vessel is inverted by 180 degrees to give a state in which SiC is immersed in the molten copper. An impregnating gas is introduced into the high-pressure vessel through a gas inlet pipe to apply a pressure to the inside of the high-pressure vessel. Thus, SiC is impregnated with the molten copper.
