  • Patent number: 7704546
    Abstract: A method and apparatus for a prosthesis. At least a portion of the prosthesis is made from a ceramic that is treated with ion implantation, which causes a controllable, bilateral compressive stress of the ceramic. A diamond-like-coating (DLC) can be coated on the ceramic and in the same chamber as the ion implantation. After treating by ion implantation and coating with DLC, the ceramic will be strengthened and have a low coefficient of friction and thereby be made much less likely to fracture under load.

  • Patent number: 7645485
    Abstract: There is provided a method for applying an improved chromium diffusion coating on an industrial item such as a turbine blade of a gas turbine engine. Chromium and other active metals are combined to form an alloy coating. Active elements include silicon, hafnium, zirconium, yttrium, tantalum, and rhenium. For producing the modified coatings through pack cementation chromium and a master alloy are mixed into a packing along with inert material and a halide activator. The packing surrounds a target in a diffusion box. The metals are then deposited by diffusion onto a target surface by pack cementation methods. The diffusion of the desired metals takes place during a coating thermal cycle. Alternatively, the diffusion can take place using an out-of-pack arrangement. Such modified coatings are utilized as improved performance coatings for environmental resistance applications over the current chromium diffusion coatings.

  • Patent number: 7575773
    Abstract: An optical compensatory sheet producing apparatus produces an optical compensatory sheet having a liquid crystal layer. In the apparatus, a rubbing unit is supplied with resin film having a first layer including resin, and subjects the first layer to a rubbing process, so as to form an orientation layer. A dust remover removes dust from the orientation layer by use of liquid such as perfluorocarbon, to which the orientation layer is insoluble. A liquid crystal layer coater is disposed downstream from the dust remover, for coating the orientation layer with coating liquid including liquid crystalline compound, so that the liquid crystal layer is formed.

  • Patent number: 7465473
    Abstract: A permanent, roughened or textured surface is applied to parts molded from polyolefins, particularly from polyethylene by applying to the surface of the part a coating mixture of a tackifier resin and polyolefin particles in a liquid carrier and incorporating a granular or particulate matter in the coating, either by application to the coating or by admixing the granular or particulate matter into the coating mixture. The coated surface is heated to the melt temperature of the polyolefin surface for a short time, sufficient to gel the polyolefin particles of the coating into the surface of the part, but insufficient to cause any thermal distortion of the part.

  • Patent number: 7387818
    Abstract: When stacking stackable items in layers on pallets, intermediate layers of paper/cardboard/film are often used for preventing loss of the items during transport. Even though the intermediate layers ensure to a large extent that items do not fall off the pallet, it cannot be entirely prevented that some of the stacked items fall off because the stacked items slid on the intermediate layers. Special intermediate layers are known, having a surface coated with non-skid coating which highly counteracts the unwanted sliding of the items in the layers stacked on a pallet. However, the laying of intermediate layers with non-skid surfaces constitutes a problem as the individual pieces of non-skid coated intermediate layer will adhere to each other. Thus, there is provided a method and a sheet dispenser where pieces of intermediate layers are successively dispensed, and where these layers are coated with a non-skid coating during dispensing.

  • Patent number: 7354621
    Abstract: In a method for forming an adhesive layer on the surface of a workpiece before the formation of a coating film containing a powder on the workpiece, the present invention provides a method for forming the adhesive layer having a desired thickness. This object is achieved by the following method: An adhesive layer formation medium m1 coated with an adhesive material is made to collide with a workpiece W so that the adhesive material is transferred from the adhesive layer formation medium m1 to the workpiece W and forms an adhesive layer on the workpiece. An adhesive layer having a desired thickness can be formed on the workpiece by regulating the thickness of the adhesive material applied to the surface of the adhesive layer formation medium (i.e. the amount of the adhesive material held by a single adhesive layer formation medium). This enables the thickness of the powder coating as the final product to be controlled as desired.

  • Patent number: 7354626
    Abstract: A direct charging electrostatic flocking method is provided for the fabrication of a fibrous structure. Fibers are deposited directly on a first electrically conductive surface while a second electrically conductive surface with an adhesive thereon is disposed over the first surface. A vacuum is created in the space between the first electrically conductive surface and the second electrically conductive surface. The vacuum is then filled with sulfur hexafluoride gas. An electric field is generated between the first and second electrically conductive surfaces. The fibers leave the first electrically conductive surface, accelerate through the electric field and sulfur hexafluoride gas, and are coupled on one end thereof to the adhesive. As a result of using sulfur hexafluoride rather than air there is an increase in fiber density of the fibrous structure.

    Abstract: A kit and a process for using it to impart wood grain appearances are provided. According to the method, a base coat comprising an opaque, pigmented, water-based paint emulsion is applied to a wood-grain textured substrate and dried. Then, a pigmented, water-based graining coat (most preferably a crosslinkable urethane/acrylic) is applied sparingly, preferably by use of a dampened foam/sponge pad or sprayed, in an amount sufficient to overcoat the base coat and color at least a majority of texture recesses in the substrate and drying. According to the kit aspect of the invention, the kit will comprise: an opaque, pigmented, water-based paint emulsion; a pigmented, water-based graining coat emulsion, optionally packaged in a bottle, such as one with a spray. Optionally, the kit can include an applicator or surface cleaner, a scraper, brush, cloth, sponge, or combination.
