  • Patent number: 7434088
    Abstract: A fault router method and system for use in a parallel redundant network environment provide additional safeguards over traditional redundant networks. Where multiple connection faults on multiple machines would ordinarily stifle communications between two or more network entities, the fault router passes packets between redundant networks to bypass connection faults. Compatibility and timing improvements allow for the extension of the parallel network environment, and provide for time-synchronized network operation.

  • Publication number: 20080107748
    Abstract: A microcapsule comprising a chemical skeleton with at least one ligand attached to the chemical skeleton. The chemical skeleton is placed within a capsule. The capsule can then separate a substance from a mixture. The capsule is placed within the mixture and the substance is allowed to enter the capsule. The substance binds to the ligand and cannot escape the capsule. The capsule is then removed from the mixture, thus removing the substance. The preferred embodiment envisions the use of the capsule to remove substances from animal digestive systems.

  • Publication number: 20070042013
    Abstract: The application relates to long acting injectable (LAI) formulations for combating ectoparasites and endoparasites in mammals. In particular, this invention provides for a LAI formulation comprising a subcutaneously volatile solvent, a biologically acceptable polymer, a bioactive agents and optionally one or more anti-ectoparasitically or anti-endoparasitically acceptable additive or excipient. Surprisingly, the liquid long acting injectable formulations of the invention solve the problems associates with previous injectable formulations by having long term stability, being able to accommodate smaller needle diameters and achieving long acting effects in the control of pests in a mammal. The unique formulations of the invention also allow for combating ectoparasites and endoparasites which have become resistant to macrolide antibiotics.

  • Publication number: 20060247464
    Abstract: The present invention provides a process for the preparation of p-toluic acid by liquid phase oxidation of p-xylene using oxygen or air as oxidant in the presence of p-toluic acid, water as solvent and cobalt salt or its combinations with salts of Ce, Mn as catalyst. Oxidation is carried out at 130-190° C. and pressure sufficient to keep water in liquid state. Oxidation step is followed by filteration to obtain p-toluic acid as major product. Unreacted p-xylene is recovered and recycled and the catalyst is recovered from aqueous phase and is recycled.

  • Patent number: 6968737
    Abstract: The present invention is a system and method for automated position location using RF signposting. The present invention comprises a plurality of transmitting units placed throughout a service area. Each transmitting unit repeatedly transmits a signal including position information related to a position associated with the transmitting unit. The position information may be an absolute position or an encoded position based on the structure of a building in which the transmitting unit is located. A receiving unit receives the signal transmitted from a transmitting unit and determines the position of the receiving unit, based on the received indication. The transmitting units are placed to provide uniform coverage of the service area, thus providing position location indoors and in urban areas where GPS does not function properly.
