  • Patent number: 9895668
    Abstract: A process for dispersing agglomerates or clusters of particles utilizing pressure generated from volatilization of an interstitial liquid. More particularly, the method relates to infusing the particles with a first liquid, placing the infused particles in a second liquid or fluid having a higher boiling point than the first liquid and heating the composition to a temperature above the boiling point of the first liquid thereby resulting in breakage of the particles. Compositions including particles dispersed by interstitial liquid vaporization are also disclosed.

  • Patent number: 6797158
    Abstract: A method and apparatus for acoustically enhanced particle separation uses a chamber through which flows a fluid containing particles to be separated. A porous medium is disposed within the chamber. A transducer mounted on one wall of the chamber is powered to impose on the porous medium an acoustic field that is resonant to the chamber when filled with the fluid. Under the influence of the resonant acoustic field, the porous medium is able to trap particles substantially smaller than the average pore size of the medium. When the acoustic field is deactivated, the flowing fluid flushes the trapped particles from the porous medium and regenerates the medium. A collection circuit for harvesting the particles flushed from the porous medium is disclosed. Aluminum mesh, polyester foam, and unconsolidated glass beads are disclosed as porous media.

  • Patent number: 6023961
    Abstract: A micro-viscosity sensor for measuring the viscosity of a lubricant. The micro-viscosity sensor including at least one finger-like element or an array of finger-like elements vertically extending from the surface of a semiconductor base, the at least one finger-like element being oscillated at a desired frequency. The power required to oscillate the at least one-finger-like element is monitored because the power required is a function of the viscosity of the lubricant. The sensor also includes a temperature detector, wherein the thermal conductivity of the temperature detector varies in correspondence with the temperature of the lubricant. A first set of electrical contacts provides for electrical connection to the at least one finger-like element; and a second set of electrical contacts provides for electrical connection to the temperature detector.

  • Patent number: 5085783
    Abstract: A method for separating particles from a flowing fluid suspension comprises the steps of providing an elongated chamber having closed first and second ends, flowing into the elongated chamber a fluid medium in which particles to be separated are suspended, and propagating an acoustic wave through the flowing fluid medium in the chamber. The acoustic wave is directed generally along the length of the chamber and is varied in frequency within a desired frequency range including a frequency resonant to the chamber to produce stationary coincidence excitations that separate particles from the fluid medium and urges the separated particles toward the second end of the chamber. The method also includes the steps of removing the fluid medium from the first end of the chamber and removing from the chamber the particles urged toward the second end of the chamber.
