  • Publication number: 20030162865
    Abstract: A method for reducing the drag on an aqueous solution in a pipe or hose system such as a snow making system includes the introduction of drag reducing polymers into the aqueous solution prior to circulating the solution in a pipe or hose. In a preferred embodiment, the drag reducing polymers are a mixture of polyethylene oxide in a carrier solution. The introduction of the polyethylene oxide in a carrier solution reduces the overall frictional drag and therefore increases the snow making efficiency by reducing the power needed to pump the water. As a result, it is easier for greater quantities of snow to be made using existing equipment due to the increased flow rate as a result of the lower drag friction. In a preferred embodiment, the polyethylene oxide is approximately 20-30% by weight and is introduced into the water pipe so resulting concentrations are approximately 30-100 weight parts per million (WPPM).

    Abstract: The invention relates to a process for reprocessing plastic wastes, in which the plastic wastes filled into vessels are autoclaved as coherent, porous bundles with high water absorption capacity in a steam atmosphere at approximately 150.degree. to 220.degree. C., preferably 165.degree. to 190.degree. C., and melted by this means, at the end of the autoclaving process, the resulting bodies of molten plastic are at least partly dried by re-evaporating the water contained therein and are cooled.

  • Patent number: 5430127
    Abstract: Aqueous emulsions, at least 80% of which have been polymerized, are treated by a process which comprises the separate steps of: a) initially treating the emulsion with a sufficient amount of a free radical generator in an amount and for a time sufficient to reduce the residual monomer content to from about 1500 to about 6000 part per million, and b) subsequently subjecting the emulsion to steam stripping under vacuum, without significantly degrading or destabilizing the emulsion, to thereby reduce the residual monomer content to from about 5 to about 500 parts per million.

  • Patent number: 5399597
    Abstract: The present invention provides a new and improved method of producing coating materials comprising the steps of providing a first organic material which is solid at room temperature, providing a second organic material which is solid at room temperature and which is substantially different in chemical composition from the first organic material, providing a source of supercritical fluid, providing a first container having a mechanical agitator, providing a second container, introducing the first and second organic materials and the supercritical fluid into the first container and mechanically agitating such materials and the supercritical fluid, and discharging the contents of the first container into the second container so as to collect substantially all of the first and second organic materials in the second vessel, the second container being maintained at a lower pressure than the first container.

  • Patent number: 5232975
    Abstract: A process for preconsolidating a planar porous fiber-thermoplastic resin layer which is unconstrained in the inplane directions by heating the layer to above the melting point of the resin, then applying pressure to the plane of the layer causing resin flow, thus orienting the fibers in the plane of the layer.

  • Patent number: 5137942
    Abstract: The method of compounding a high strength, cost-effective, composite of a high temperature, water sensitive, polar, polyamide-inide resin mixed with a talc, water absorbent/adsorbent filler. The method comprises raising said mixture to a temperature of about; 500.degree. F. to develop plasticity in said engineering resin. Thereafter there is added a lower temperature softening, water repellant, polypropylene resin and a compatibilizing additive. Finally all components are mixed in a mixing chamber sufficiently to obtain complete dispersion and homogeneity of the composite.
