  • Patent number: 6971431
    Abstract: A tape dispenser for applying adhesive tape to a substrate surface. The dispenser includes an exterior application surface with an opening therein. A plurality of rotatable cylindrical rollers are mounted within the housing, wherein the surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface. At least two of the plurality of rollers are opposed rollers that engage the tape surfaces therebetween. The outer surface of at least one of the plurality of rollers protrudes through the opening enabling frictional contact of the roller surface with the substrate surface. When the dispenser is drawn over the surface, the outer surface of the this roller engages and rolls over the substrate surface. It also coacts with the outer surfaces of the other rollers, causing them to grip the tape and feed it through the opening, enabling the adhesive tape to be applied to the substrate surface.

  • Patent number: 6964718
    Abstract: Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.

  • Patent number: 6960554
    Abstract: A method of making an oxide superconductor article includes converting an oxide superconducting precursor into an oxide superconductor by thermo-mechanical processing using intermediate rolling deformation and heat treatment (including liquid-phase sintering and low temperature baking) and applying an additional heat treatment after the material is fully processed (including optional liquid-phase sintering and low temperature baking) to decompose any secondary phase remaining at the grain boundaries and to promote diffusion of the secondary phase into the oxide grain, where they form 2223 phase. The material has a better superconducting grain connectivity and improved superconducting transport property.

  • Patent number: 6884384
    Abstract: A method for making a thermal insulating material includes the steps of: providing a chamber, placing hollow geometric shapes in the chamber, closing the chamber, evacuating air from the chamber, feeding a slurry into an adjacent slurry chamber, pressurizing the slurry chamber and forcing the slurry in to the sphere chamber around the spheres against a fibrous material adjacent a side wall of the sphere chamber. The fibrous material allows capillary wicking of the liquid from the slurry around the spheres. Due to this pressure the spheres and slurry are semi dried into a green state. The material in its green state green is subsequently dried and fired to form the insulating material.

  • Patent number: 6878313
    Abstract: To furnish stably a sintered nuclear fuel compact of uranium dioxide with a large grain diameter, a fabrication method therefor requires sintering a starting material at two stages in an oxidizing atmosphere and in a reducing atmosphere at relatively low temperatures. The starting material is either a powder mixture of uranium dioxide fresh material powder and triuranium octaoxide in a weight ratio of 75/25 ˜ 55/45 or pulverulent mixed uranium oxides yielding a final O/U ratio equal to that of the powder mixture. The sintering process in the oxidizing atmosphere involves at least one time period of a temperature rise to a higher temperature of 1200 to 1100° C. and at least one time period of a temperature drop to a lower temperature of up to 1080° C. A temperature difference between the higher and lower temperatures is preferred to be 50° C. or more.

  • Patent number: 6872254
    Abstract: A method and apparatus for forming a generally uniform liquid layer on a surface of an upper surface microelectronic substrate. The apparatus can include a support that engages less than the entire lower surface of the microelectronic substrate and rotates the microelectronic substrate at a selected rate. A barrier can extend over the upper surface of the microelectronic substrate and can rotate at about the same rate as the substrate to separate a rotating air mass adjacent to the upper surface and within the barrier from a stationary air mass external to the barrier. The rotating air mass can reduce the likelihood for liquid/air interface disturbances that create non-uniformities in the liquid layer. Accordingly, the method and apparatus can increase the range of thicknesses to which the liquid layer can be formed and can reduce the topographical non-uniformities of the liquid layer.

  • Patent number: 6869550
    Abstract: A pre-alloyed stabilized zirconia powder suitable for use in thermal barrier applications is formed by alloying zirconia with a stabilizer, such as yttria, and processing the alloyed stabilized zirconia to form a very fine powder. The raw powder is then spray-dried to produce an agglomerated powder having an average particle size suitable for use in spray coating applications. The resulting powder can be used in a thermal-spray application to produce a porous thermal barrier coating having a substantially decreased thermal conductivity when compared to conventional TB coatings, such those produced using plasma-densified powders.

  • Patent number: 6869552
    Abstract: An improved lost wax method for fabricating dental devices, a prefabricated incisal veneer (1) is selected from among a group of said veneers having predetermined shapes, shades, and sizes. Wax is applied (2 and 3) to the incisal veneer to create a wax buildup onto a model (4) or prefabricated coping (5). Subsequently, a sprue is attached to the applied wax (2 and 3) and the wax buildup is removed from the model (4) for investing and burnout to create a lost wax mold. For a crown with a substructure, the incisal veneer (1) and the coping (5) are both cast in place with press ceramic, press thermoplastic material, or by injecting a curable resin, composite, or epoxy material into the lost wax mold.

  • Patent number: 6858083
    Abstract: For weld bonding polymeric components, a bond monitoring device is utilized to sense emissivity from a bonding site to preferably determine the temperature of the material at the surface of the bonding site, in order to provide feedback information to a current generator that controls the thermal energy that is transferred to the bonding site. The bond monitoring device preferably comprises an infrared detector or pyrometer that determines the temperature at the surface of the bonding site by sensing the infrared radiation, which information is used to control current generation. The current generation device preferably comprises a radio-frequency current generator, which RF current is controllably used to create a magnetic field within a magnetic flux concentrator. When used with an mandrel of magnetically permeable material that is positioned close to the magnetic flux concentrator, the mandrel can generate resistive heat based directly on the supply of RF current.

  • Patent number: 6849143
    Abstract: The invention relates to a method for laying a floor covering that includes a flexible material containing a thermoplastic wear layer made from, in particular, plasticized PVC. The basic panels that form the covering are glued to the ground and cold welded in between on the site to be covered. After a panel has been positioned and glued to the surface to be covered, a continuous bead of mastic, which is made on the actual site by mixing a hardener and a polyurethane resin in aqueous phase, is applied laterally along the entire depth of the covering. The next panel is positioned on the ground which is covered with adhesive and the lateral edge thereof is pinned against the edge of the preceding panel comprising the bead of mastic, thereby causing the excess material to come to the surface, where it is removed by simply wiping with water.
