  • Patent number: 10501670
    Abstract: A dielectric fluid and coolant for electrical apparatuses such as transformers. In one embodiment, the fluid contains more than 25% biobased base oil, such as a biobased hydrocarbon oil, which has a molecular weight greater than 300 g/mol and less than 595 g/mol. The biobased base oil may optionally be blended with other oils, such as mineral oils and vegetable oils.
    Type: Grant
    Filed: March 17, 2015
    Date of Patent: December 10, 2019
    Assignee: Novvi LLC
    Inventors: Hyeok Hahn, Jeffrey Brown, Paula Vettel, Jason R Wells

  • Patent number: 8858066
    Abstract: Methods, systems, and apparatus, including computer program products and implementing techniques for mixing liquid components. Quantities of two or more liquid components are transferred from pressurized source reservoirs to one or more destination locations by means of a fluid outlet that includes a dispense valve, and the two or more liquid components are mixed in the destination locations to create a plurality of fluid mixtures. Two or more dispensing technologies can be combined to provide for increased efficiency in the dispensing of high volume liquid components. The amounts of liquid components being dispensed can be monitored during the dispensing to provide feedback control of the dispensing.
    Type: Grant
