    Abstract: A closed-loop system and process is used for applying fire retardant chemicals to fibers. Fibers are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. Recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

  • Patent number: 6926763
    Abstract: The invention features compounds of the formula: or a pharmaceutically acceptable salt thereof, wherein A is CR2 and B is N; wherein n is 0-3; wherein R1 is (CH2)m—{(G)o—(CH2)p}q—L, in which G is CH2, CH?CH, C?C, CO, O, S, or NR5, where R5 is H or C1-6 alkyl, CHR6, where R6 is OH or C1-6 alkyl, CH(CR7R8), where each of R7 and R8 is, independently, H, halo, or C1-6 alkyl, OCO, CONR9, NR10CO, where each of R9 and R10 is, independently, H or C1-6 alkyl, SO2NH, or NHSO2; in which m is 1-4, o is 0-4, p is 0-4, and q is 0-4. The compounds disclosed herein have potent anti-microbial, e.g., both Gram-positive and Gram-negative anti-bacterial properties. The compounds inhibit DNA polymerase IIIC and DNA polymerase IIIE enzymes and thus act therapeutically by inhibiting the growth of a broad array of bacteria. The compounds can be administered to prevent or to treat Gram-positive or Gram-negative bacterial infections, e.g., in eukaryotic cell cultures, animals, or humans.

  • Patent number: 6896908
    Abstract: This invention relates to a leach-resistant borate preservative for lignocellulosic-based products, providing resistance against insect and fungal attack for use in exterior and ground contact applications. The preservative compositions of this invention may be provided as a high strength liquid concentrate, suitable for transportation, storage and easy on-site dilution, or as a ready-to-use treatment solution. These wood preservative compositions include a borate preservative component and a co-biocidal metal fixative such as copper or zinc. The preservative compositions also contain volatile organic acid, free ammonia and ammonium salts to aid dissolution. Methods for the application of these preservative compositions to wood are also provided.

  • Patent number: 6893752
    Abstract: A mold-resistant gypsum panel includes a core of an interlocking matrix of calcium sulfate dihydrate crystals, a facing material on at least one side of the panel and a salt of pyrithione dispersed through both the core and the facing materials. A method of making a mold-resistant gypsum product is also provided. A slurry of calcined gypsum, water and a water-soluble pyrithione salt is formed, then deposited on a sheet of facing material. The slurry on the facing material is shaped into a panel and maintained under conditions sufficient for the calcined gypsum to react with the water to form a core comprising an interlocking matrix of set gypsum crystals. Heating of the panel causes evaporation of the water that did not react with the calcined gypsum.

  • Patent number: 6827766
    Abstract: Improved area decontamination products and methods of use thereof are provided which include reactive nanoparticles (e.g., metal oxides, hydroxides and mixtures thereof) with one or more biocides and a liquid carrier for the nanoparticles and biocide(s). The products may be formulated for area decontamination as sprays, fogs, aerosols, pastes, gels, wipes or foams, and the presence of reactive nanoparticles enhances the neutralization of undesirable chemical or biological compounds or agents. The nanoparticles may be from the group consisting of the alkali metal, alkaline earth metal, transition metal, actinide and lanthanide oxides and hydroxides and mixtures thereof. In preferred forms, nanocrystalline oxides and hydroxides of Al, Ca, Ce, Mg, Sr, Sn, Ti and Zn are employed having single crystallite sizes of up to about 20 nm and surface areas of at least about 15 m2/g.
