  • Patent number: 8581158
    Abstract: An electrically conductive coating composition is provided for use on aircraft and other substrate surfaces to prevent the formation of ice or to melt ice. The conductive coating composition may include a nanomaterial such as carbon nanotubes dispersed in a solvent which may be applied to a substrate surface to form a thin film which is resistively heatable. The conductive coating may also comprise a nanomaterial formed from carbon nanotubes or fullerenes grafted to a polymer containing an active functional group which renders a substrate surface icephobic and is also resistively heatable.

  • Patent number: 8357643
    Abstract: A lubricant from plant and/or animal oils and fats; methods for producing a lubricating oil, and the oil produced thereby. The lubricant is derived from an animal or plant fat or oil having an iodine number above about 7, and produced by epoxi-dising the fat or oil and (1) reacting the epoxidised fat or oil with a carboxylic acid anhydride in the presence of a basic catalyst to produce a diester, or (2) hydrogenating the epoxidised fat or oil to generate mono-alcohols and acylating the alcohol functionality with acid anhydrides, acid chlorides or carboxylic acids to produce a mono-ester.

  • Patent number: 8222367
    Abstract: A proton conducting hydrocarbon-based polymer has acid groups on side chains attached to the main chain, where the acid groups are between 7 and 12 atoms away from the main chain. Another polymer includes a semi-fluorinated aromatic hydrocarbon main chain and side chains that include at least one —CF2— group and an acid group. Another polymer includes an aromatic hydrocarbon main chain and side chains that include at least one —CH2-CF2— group and an acid group. Another aromatic polymer includes acid groups attached to both the main chain and the side chains where less than about 65 weight percent of the acid groups are attached to the side chains. Another aromatic polymer includes side chains attached to the main chain that include at least one aryl ring, and acid groups attached to both the main chain and to the aryl groups. Another polymer includes an aliphatic hydrocarbon main chain, side chains that include at least one deactivating aryl ring, and acid groups attached to the deactivating aryl rings.

  • Publication number: 20100093966
    Abstract: Broadly the invention provides for a deinkable toner composition, an image made with the deinkable toner, and a method for making the toner including a coloring agent; a thermoplastic polymer; and a protein. In another embodiment the toner includes a coloring agent and a thermoplastic polymer where the protein has been incorporated into the polymer itself. In typical embodiments the protein is derived from soybeans but may be from other plant or animal sources. Typically the toner has a positive triboelectric charge of between about 10 to about 40 microCoulomb/g, or a negative triboelectric charge of between about 10 to about 40 microCoulomb/g.

  • Publication number: 20050196441
    Abstract: The present invention provides a manufacturing process for quick dissolving products having active ingredients directed to agrochemical applications, such as plant applications and animal and animal health applications. Electrohydrodynamic (EHD) spraying is used to form a product form preferably comprised of fibers that contains a desired agrochemical compound formulated to quickly disintegrate on contact with a solvent such as water. The dispersed chemical is then provided as a sprayable solution. Because the product form contains little or no liquid, significant size and weight savings are gained, higher active ingredient loadings may be placed in a smaller amount of material, and manufacturing, packaging and transportation costs are thereby reduced without impacting user-friendliness. In addition, the EHD manufacturing method of the present invention also permits combining active ingredients previously not capable of effective use together in a single product.
