  • Patent number: 6623832
    Abstract: A sealing strip, such as for fitting to the frame of a door opening in a motor vehicle body, comprises a longitudinally extending channel-shaped mounting portion incorporating a channel-shaped reinforcing carrier. The hollow tubular longitudinally extending sealing portion is attached to the outside of the mounting portion. When such a strip is bent to follow curves in the door frame, the increased tension in the mounting portion at the curves can cause the sealing portion to move inwardly of the curve so as partially the bridge across the curve. In order to avoid this, the sealing strip, and particularly the mounting portion are longitudinally compressed at positions corresponding to the positions where curves are to be formed in the strip. This local longitudinal compression helps to maintain the sealing portion in its correct attitude.

  • Patent number: 6616965
    Abstract: Tantalum and niobium aluminum-doped hydrated mixed metal oxide sols may be made by a process comprising combining a first metal compound aluminum alkoxide, with a second metal compound selected from the group consisting of niobium alkoxide and tantalum alkoxide, and mixtures thereof to provide a substantially water-free precursor and combining the precursor with a ketone to provide a hydrated mixed metal oxide sol, wherein the ketone is substantially free of water. The sol may then be processed to obtain thin films, fibers, crystals (both micro- and meso-porous), powders and macroscopic objects and to provide mixed metal oxide that may be used in a variety of components of integrated circuits.

  • Patent number: 6602547
    Abstract: A new fluidized bed particle coating method is disclosed by the use of which coatings can be uniformly and conveniently deposited on the surfaces of fluidized particulate materials by vapor deposition processes at temperatures lower than those of the heated coating precursor transport lines. By this method, particle materials with relatively low surface temperatures may be brought into close proximity with a coating precursor containing gas stream characterized by a substantially higher gas volume temperature in such a way that the vaporized precursor molecules are caused to adsorb or condense on the relatively cold particle surfaces without also condensing on any other surface. Further, if the adsorbed precursor molecules are capable of reacting or polymerizing on the relatively cold particle surfaces, thus forming substantially continuous coatings on those surfaces, they may do so without also depositing such coatings on any other surfaces.

  • Patent number: 6592938
    Abstract: The invention relates to a method for coating particles thus obtained. According to the inventive method, the particles that are to be coated and at least one organo-metallic complex precursor of the coating material are brought into contact with each other in a liquid containing one or several solvents, whereby said particles are maintained in a dispersion in the liquid which is subjected to temperature conditions and supercritical pressure or slightly sub-critical pressure conditions; the precursor of the coating material is transformed in such a way that it is deposited onto the particles, whereupon the liquid is placed in temperature and pressure conditions so that it can eliminate the solvent in a gaseous state. The invention can be used to coat nanometric particles in paticular.

  • Patent number: 6586104
    Abstract: A coating liquid for forming a transparent coating comprising fine particles of an inorganic compound and a hydrolyzate of an organosilicon compound represented by the general formula (I): RnSi(OR′)4−n  (I) wherein R and R′ represent organic groups which may be identical to each other or different from each other, and n is an integer of 1 to 3. This coating liquid ensures excellent substrate wettability and compatibility with various organic solvents so that the printability and applicability thereof are desirable, with the result that a transparent coating film of high uniformity, for example, a flattening coating film, can be formed. The present invention comprises a substrate having a transparent coating film formed on the substrate surface from the above coating liquid.

  • Patent number: 6555177
    Abstract: A ceramic-based hardwood floor finishing method resistant to panelization, exhibiting improved durability, and suitable for on-site use. The method is comprised of laying down successive layers of water-based primer, armor coat and top coat. The water-based primer utilizes a low resin content and a low co-solvent concentration to substantially reduce panelization of hardwood boards. The water-based armor coat is comprised of large particulate size ceramic additives which, in combination with a low resin content, allow the formation of a microscopic bead structure on the surface of the finish which provides enhanced durability.
