  • Patent number: 9840807
    Abstract: A method for: (1) The application of solvent-based resin formulations to various forms and classes of textile fibers, fabrics, and finished goods which, when dyes or pigments are included, will impart color to textile materials; (2) The application of the formulations to various forms of rubbers, natural and synthetic, in the pre-formed state or subsequent to forming a finished product which will impart color and fortification; (3) The application of the same group of formulations to revitalize plastic surfaces and impart color to plastics prior to and subsequent to forming finished products; (4) The application of the same formulations to polymers for the purpose of carrying additives for purposes such as, but not limited to, sizing, mildew resistance, UV protection, glazing, creation of printable or paintable surfaces, artistic coloring effects, abrasion resistance, stain resistance, mercerizing, and many more, with or without dyes or pigments included.

  • Patent number: 9469660
    Abstract: Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

  • Patent number: 8388748
    Abstract: The present invention relates to the continuous preparation of alcohol- and plasticizer-free finished nitrocellulose solutions having a particularly low water content by partial distillative falling-film evaporation of comparatively water-rich, optionally emulsion-like crude nitrocellulose solutions which are preferably provided by dissolving nitrocelluloses of the customary solid forms offered, which are known to be initially water-moist as a result of the preparation, in preferably ethyl acetate.
