  • Patent number: 7256425
    Abstract: A product produced in a PVD method is described, which consists of thin plane-parallel structures having a thickness in the range from 20 to 2000 nm and small dimensions in the range below one mm. Production is carried out by condensation of silicon suboxide onto a carrier passing by way of the vaporisers. The carrier is pre-coated, before condensation of the silicon suboxide, with a soluble, inorganic or organic separating agent in a PVD method. All steps, including that of detaching the product by dissolution, can be carried out continuously and simultaneously at different locations. As final step, the SiOy may be oxidised to SiO2 in an oxygen-containing gas at atmospheric pressure and temperatures of more than 200° C. or SiOy may be converted to SiC at the surface of the plane-parallel structures in a carbon-containing gas at from 500° C. to 1500° C. The products produced in that manner are distinguished by high uniformity of thickness.

  • Patent number: 6872444
    Abstract: Coating compositions, methods and articles of manufacture comprising a nanoparticle system employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces, are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of coating compositions, methods and articles of manufacture that create multi-use benefits to the modified surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that, in some embodiments, may include at least one of the following improved surface properties: cleaning, wettability, liquid strike-through, comfort, stain resistance, soil removal, malodor control, modification of surface friction, reduced damage to abrasion and color enhancement, relative to the surfaces unmodified with such nanoparticle systems.

  • Patent number: 6837918
    Abstract: A process and apparatus collects pigment nanoparticles by forming a vapor of a pigment that is solid at room temperature, the vapor of the pigment being provided in an inert gaseous carrying medium. At least some of the pigment is solidified within the gaseous stream. The gaseous stream and pigment material is moved in a gaseous carrying environment into or through a dry mechanical pumping system. While the particles are within the dry mechanical pumping system or after the nanoparticles have moved through the dry pumping system, the pigment material and nanoparticles are contacted with an inert liquid collecting medium.

  • Patent number: 6824604
    Abstract: The invention relates to coloring pigment granulates and a method for producing the same. The aim of the invention is to provide a granulate and a method for economically producing the same. The granulate disintegrates very quickly once added to a building material that is to be colored. To this end, the granulates are comprised of granulate cores which do not contain binding agents, which have a granular size ranging from 0.1 to 8 mm and which are enclosed by an enveloping layer made of a material that can be broken down. In addition, the granulates have a moisture content <30% and the granulates that do not contain binding agents are produced in a pregranulator, are compacted immediately after granulation and are subsequently subjected to a screening process. Lastly, the useful granular fraction that has been separated out during the screening process is enclosed with an enveloping material.

  • Patent number: 6749936
    Abstract: Achromatic multilayer diffractive pigment flakes and foils are provided having diffractive structures thereon. The diffractive pigment flakes can have a symmetrical stacked coating structure on opposing sides of a reflective core layer, an asymmetrical stacked coating structure on one side of a reflective layer, or can be formed with one or more encapsulating coatings around the reflective core layer. The diffractive pigment flakes can be interspersed into liquid media such as paints or inks to produce diffractive compositions for subsequent application to a variety of objects. The foils can be laminated to various objects or can be formed on a carrier substrate. The diffractive pigment flakes and foils can be formed with a variety of diffractive structures thereon to produce selected optical effects. The diffractive foils and diffractive compositions applied to an object exhibit an iridescent diffractive effect over an achromatic background.

  • Patent number: RE39339
    Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria.
