  • Patent number: 9637593
    Abstract: Organic materials are stripped and dried in a single column having two contact zones. A stripping gas is introduced into an upper contact zone and flows through the organic material in that zone. A drying gas is introduced into a lower contact zone. The drying gas contacts the organic material in both the upper and lower contact zones, and is removed from the top of the column together with the stripping gas. This process permits very efficiently removal of volatile organic compounds as well as efficient drying, while requiring on low levels of the stripping and drying gasses.

  • Patent number: 9637612
    Abstract: A method for alignment of high aspect ratio materials (HARMs) within a liquid matrix by means of magnetic particles. The application of an external magnetic field creates a forced motion of the magnetic particles. This in turn leads to a laminar flow within the matrix which imposes a drag force on the HARMs, aligning the HARMs across the matrix. The used magnetic particles eventually accumulate at one end side of the matrix container and can be removed either by an incision or an extraction process. Unlike the previously proposed methods, there is no need for the magnetic particles to be attached either physically or chemically to the HARMs. Thus, the ultimate aligned HARMs are mostly pure and free of any magnetic particles. Once the matrix is a polymeric solution, the mentioned method is capable of synthesis of aligned HARMs-polymer composites, which exhibit improved mechanical and electrical properties.

  • Patent number: 9637635
    Abstract: A method of waterproofing or damp proofing a protected member having a surface with a sulfur-extended elastomer asphalt binder composition uses a sulfur-extended elastomer asphalt binder composition that includes elemental sulfur, an elastomer and an asphalt binder. The method includes the steps of combining the elastomer with the asphalt binder maintained at an elastomer mixing temperature such that an intermediate asphalt binder mixture forms, and combining elemental sulfur with the intermediate asphalt binder maintained at a sulfur mixing temperature such that the sulfur-extended elastomer asphalt binder composition forms. The method also includes the step of applying the sulfur-extended elastomer asphalt binder composition to the surface of the protected member such that the sulfur-extended elastomer asphalt binder composition contacts, adheres to and forms a layer upon the surface of the protected member. The asphalt binder composition is applied at a temperature no greater than 145° C.

  • Patent number: 9637638
    Abstract: The present invention provides an iron oxide-coated layered silicate pigment that has no interference color, strongly exhibits the color inherent in iron oxide, and is excellent in gloss. The pigment of the present invention is an iron oxide-coated layered silicate pigment comprising a layered-silicate plate particle as base, and an iron oxide coated on the plate particle; wherein the iron oxide does not coat the surface portion of the plate particle or the iron oxide is localized on the edge portion rather than the surface portion of the plate particle. As the iron oxide, at least one kind selected from black iron oxide (Fe3O4) and red iron oxide (Fe2O3) can be used preferably. As the layered silicate, a mica-group layered silicate can be used preferably. The iron oxide-coated layered silicate pigment of the present invention can be incorporated into cosmetic preferably.
