  • Publication number: 20060166843
    Abstract: Polymeric additives are disclosed for compressor lubricants which can reduce the tendency of the lubricant to become entrained in compressed gases and be carried forward as fine dispersed droplets in compressed gas systems such as compressed air, natural gas, and compression refrigeration systems.

  • Publication number: 20060020073
    Abstract: A process of forming a gel for gel packed transmission cable comprising the steps of dissolving a high molecular weight polymer in oil and thereafter through the use of a rotor and stator mixer effectively incorporating a colloidal silica(s) into the polymer in oil composition. Compositions made from this process having optimized viscosity are also claimed.

  • Patent number: 6195664
    Abstract: A system and method for controlling the conversion of a file from an input format to an output format is provided. The method includes a computer-implemented method for controlling the conversion of a computer file from an input format to an output format by determining the best path for converting the file from the input format to the output format using family objects. The method includes the steps of receiving the input format and the output format, and generating a node in memory for each family object that can read the input format. The method further includes the step of generating successful branches of nodes in memory that include one or more nodes such that each successful branch includes a first node that can read the input format and a last node that can write the output format. Finally, the method includes calculating a best path through the successful branches of nodes.
