Pearl Crossen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low viscosity functional fluids
    Patent number: 8846588
    Abstract: Low viscosity functional fluids are described which comprises methoxy polyethylene glycol. The fluids are particularly well-suited for use as DOT 4 brake fluids and provide high ERBP, WERBP, low kinematic viscosity and low SBR volume % increase.
    Type: Grant
    Filed: June 22, 2011
    Date of Patent: September 30, 2014
    Assignee: Dow Global Technologies LLC
    Inventors: Pearl Crossen, Jin Zhao

  • LOW VISCOSITY FUNCTIONAL FLUIDS
    Publication number: 20070027039
    Abstract: The fluid compositions of the present invention include an alkoxy glycol component, where the composition includes no more than about 10 wt % of a borate ester based on the weight of the composition. The physical properties of the compositions of include a high dry equilibrium reflux boiling point (ERBP), a high wet equilibrium reflux boiling point (WERBP), and a low temperature viscosity. These compositions are particularly useful because their physical properties (e.g., WERBP, ERBP, and low temperature viscosity) meet or exceed the provisions for DOT 3 brake fluids under the Federal Motor Vehicle Standard No. 116.
