  • Patent number: 7714056
    Abstract: Thermoplastic polymers, rubbery polymeric components and reinforcing fillers are mixed and heated to a range of 380° F. to 440° F. The resulting mixture is then fed into a Banbury mixer, with the resulting mixture fed into a diverter feeding two molds. The velocity of the piston of each mold being filled is controlled to thereby control the density of the molded product along its length. As each mold is filled, it is deposited in a cool water bath (50° F.-60° F.) while the next mold is being filled. The molds are sequentially transferred to an air cooling rack to complete the process. A texture, generally comprising indentations perpendicular to the longitudinal axis on the molded object, provides a frictional surface between the railway crosstie and the ballast beneath the crosstie.

    Abstract: The present invention relates to random form of nanoscale silicate plates produced by a process using an exfoliating agent. The exfoliating agent used in the present invention has the formula: where n=1 to 5 wherein n=1 to 5 and R is a polyoxypropylene group, poly(oxyethylene/oxypropylene) group, or polyoxyethylene group. In this invention, layered silicate clays are exfoliated into random silicate plates by acidifying AMO with inorganic acid, adding the acidified AMO to layered silicate clay with agitation, and adding sodium hydroxide or chloride of alkali metal or alkaline-earth metal, in ethanol, water and a hydrophobic organic solvent to the intermediate product and repeating phase separation procedures to isolate random silicate plates from water phase.

  • Patent number: 7635729
    Abstract: Zinc oxide and/or zinc carbonate coated particles, methods of coating particles with zinc oxide and/or zinc carbonate, and various applications of such coated particles, including applications in cosmetics, rubber, and other polymer materials, are disclosed. As compared to rubber formulations with zinc oxide and core materials added separately, formulations including the present coated particles may have a higher transparency, lower Mooney viscosity and lower minimum torque, improved dispersability, a higher modulus at 100% and/or at 300% elongation, a higher tensile strength, better aging resistance, better abrasion resistance, lower density, and/or lower heat build up. Thus, products containing the present coated particles may enjoy similar or better properties than comparative products that include a conventional filler and/or zinc oxide per se, and the present coated particles may result in cost savings for the corresponding product formulations.
