  • Patent number: 7074479
    Abstract: Porous coatings on high-performance ceramics attempt to combine the mechanical and thermal characteristics, which fulfil stringent demands, of the substrate material with the advantageous properties of coating materials. The subsequent application of layers of this type to the pre-sintered substrate produces unsatisfactory results in several areas of use with regard to possible layer thickness, porosity and adhesion. According to the invention, a shaped body consisting of a sintered, inorganic material, whose surface comprises a porous layer is produced in such a way that the base body is first formed as a green body. A layer in the form of a suspension, also containing an inorganic material, is then applied to the surface or to one section of the surface of the base body. A predetermined fraction of a pore-forming substance is mixed with at least the material of said layer and the green body with its applied layer is subjected to the thermal treatments required for producing a monolithic sintered body.

  • Patent number: 6596404
    Abstract: This invention pertains to a siloxane resin composition comprising R1SiO3/2 siloxane units, R2SiO3/2 siloxane units and (R3O)bSiO(4-b)/2 siloxane units wherein R1 is an alkyl group having 1 to 5 carbons, hydrogen, or mixtures thereof; R2 is a monovalent organic group having 6 to 30 carbons; R3 is a branched alkyl group having 3 to 30 carbons, b is from 1 to 3; and the siloxane resin contains from 2.5 to 85 mole percent R1SiO3/2 units, 2.5 to 50 mole percent R2SiO3/2 units and 5 to 95 mole percent (R3O)bSiO(4-b)/2 units. The siloxane resin is useful to make insoluble porous resin and insoluble porous coatings. Heating a substrate coated with the siloxane resin at a sufficient temperature effects removal of the R2 and R3O groups to form an insoluble insoluble porous coating having a porosity of 1 to 60 volume percent and a dielectric constant in the range of 1.5 to 3.0.

  • Patent number: 6579396
    Abstract: A durable, low-density, high performance insulating material is suitable for use as a high temperature thermal and acoustic insulation. The insulation includes fiber batting made with non-thermoplastic fibers or blends of fibers such as aramid fibers and ceramic fibers, which are bound within at least some interstices by high temperature non-flammable thermoplastic binder such as polyphenylene sulfide. In addition, a fireblocking layer can be provided on at least one surface of the insulation to further improve fire ablation or flame retardance.

  • Patent number: 6521053
    Abstract: A substrate is protected by first providing the substrate, and applying a ceramic coating overlying and bonded to the substrate. The ceramic coating is formed of an open-cell solid foam of ceramic cell walls having an interconnected intracellular volume therebetween which is filled at least in part with a metallic alloy. The ceramic coating has an exposed surface remote from the substrate. The exposed surface of the ceramic coating is heated to an exposure temperature such that at least some of the metallic alloy is lost from the intracellular volume.

  • Patent number: 6491977
    Abstract: The present invention relates to a method and apparatus for forming a layer of blown cellular polyurethane on a textile material, such as a carpet backing. The method includes applying to a textile material a layer of reactive polyurethane forming agents containing a sufficient amount of water or heat-sensitive blowing agent so as to cause chemical blowing of the mixture when heated sufficiently, heating the layer so as to cause chemical blowing of the mixture and applying to the layer during the chemical blowing thereof a pressure of an amount and for a time sufficient to control the blowing of the mixture to a desired degree, the pressure being applied to the mixture continuously from an initial pressure to a final pressure, wherein said initial pressure is greater than the final pressure. Apparatus for performing the process is also disclosed.

  • Publication number: 20020072128
    Abstract: Methods and compositions are provided for producing arrays of polymeric binding agents. In the subject methods, the individual polymers of the array are synthesized using solid phase synthesis techniques on the surface of a substrate. A critical feature of the invention is that one or more locations on the substrate surface are spatially and temporally protected by a protective bubble during the synthesis protocol, where the protective bubble may be produced using any convenient bubble producing means. The bubble producing means may be a component of either a substrate or a structure separate from the substrate. Also provided are the arrays produced by the subject methods, kits for use in practicing the subject methods, and methods of using the arrays in analyte detection assays, including hybridization assays, such as gene discovery, differential gene expression and gene sequencing assays.

  • Patent number: 6376014
    Abstract: A spinning cone is positioned directly below a mixing head outlet to dispense and distribute a sticky mixture of polyurethane foam liquid chemical components. The mixing head and cone are reciprocated together across a longitudinally advancing metal strip to substantially uniformly distribute the mixture thereon. The procedure is practised in connection with the fabrication of overhead door insulated panels. In the prior art, plugging of dispensers would commonly occur within minutes, due to a build-up of adhering mixture on a surface followed by foaming. The spinning cone has dispensed satisfactorily for hours at a time.
