  • Publication number: 20050181152
    Abstract: A reticulated polyurethane foam having a density less than 1.0 pounds per cubic foot [16 kg/m3] forms an explosion suppressing material that is installed into the inner volume of a fuel tank to fill from 50 to 90% or up to 100% of the volume of such tank. The reticulated polyurethane foam has particular advantage when used in a fuel tank for an aircraft.

  • Patent number: 6720307
    Abstract: Novel analogs of fusidic acid are described with one or more carbohydrate units attached. Certain glycosylated analogs of fusidic acid have enhanced solubility properties in diluents or excipient of choice as compared to unmodified fusidic acid. Certain glycosylated analogs may be employed as chemotherapeutic agents and particular analogs may be useful for fighting anti-microbial infections.
    Type: Grant

  • Patent number: 6344494
    Abstract: The present invention discloses a method for the formation of a flexible slabstock polyurethane foam having substantially improved indentation force deflection and resilience characteristics while maintaining the other physical properties. The method comprises the steps of reacting a triol polyoxyalkylene polyether polyol having a plurality of internal blocks formed from oxyalkylene monomers with a plurality of terminal caps comprising ethylene oxide attached to said plurality of internal blocks, the internal blocks containing at least 80% by weight propylene oxide based on the total weight of all of the oxyalkylenes in said internal blocks and the amount of ethylene oxide in the terminal caps comprising from 5 to 25% by weight based on the total weight of the polyol, said polyol having a degree of unsaturation of less than or equal to 0.015 meq/g KOH with a polyisocyanate component in the presence of a catalyst and water as a blowing agent at a level of between 3 to 7% by weight.

  • Patent number: 6201035
    Abstract: The present invention discloses a method for the formation of and a flexible slabstock polyurethane foam having substantially improved indentation force deflection and resilience characteristics while maintaining the other physical properties. The method comprises the steps of: forming a polyol blend having a nominal functionality of at least 2.3 by combining at least one polyether polyol having a plurality of terminal ethylene oxide caps of from 5 to 25% by weight based on the total weight of the polyether polyol, a molecular weight of greater than or equal to 4000 Daltons, and an unsaturation of greater than 0.04 meq/g KOH; at least one graft polyether polyol having an equivalent weight of greater than 1000 Daltons, a solids content of at least 28%, and a plurality of terminal ethylene oxide caps of from 5 to 25% by weight based on the total weight of the graft polyether polyol; and at least one very low unsaturated polyether polyol having an unsaturation of less than or equal to 0.
