Pricha Klinsuttho 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).

  • Determination of isothermal secant and tangent bulk modules
    Patent number: 6279385
    Abstract: A method to measure both the isothermal secant and tangent bulk modules and the density of functional fluids. The instrumentation and methodology described in this invention use much smaller volumes of fluids which permits the measurement of these critical properties on experimental fluids which are available in only limited quantities.
    Type: Grant
    Filed: May 3, 1999
    Date of Patent: August 28, 2001
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: Arthur A. Krawetz, Phat A. Phan, Pricha Klinsuttho
  • Method for the measurement of bulk modulus and pressure viscosity of liquids
    Patent number: 5383352
    Abstract: A method is disclosed for determining bulk modulus of a liquid based on a pressure-volume-temperature relationship at constant volume corrected for changes in system volume due to elevated pressure and temperature. The apparatus used to determine bulk modulus comprises a pressure vessel in which the liquid to be tested is introduced, and from which all gases are removed. The vessel is placed in a constant temperature oven and the pressure is recorded. The method for determining bulk modulus and density requires calibration of the vessel volume changs due to pressure and temperature.
