Patents by Inventor Daniel A. Armstead

Daniel A. Armstead 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).

  • Publication number: 20220041914
    Abstract: A method of hydrating a dry powdered viscosifier such as a powdered polymer is disclosed. The method includes mixing the powdered viscosifier with a solvent such as water to form a mixture; moving the mixture through a cavitation zone; inducing energetic shock waves and pressure fluctuations in the mixture by mechanically inducing cavitation events within the mixture, the shock waves and pressure fluctuations untangling, separating, and straightening polymer molecule chains and distributing the chains throughout the mixture, and extracting the resulting hydrated viscosifier from the cavitation zone.

  • Patent number: 10173191
    Abstract: A controlled cavitation reactor is disclosed that is particularly suited to the treatment of abrasive fluids and slurries with a minimum of erosion and mechanical failure caused by abrasion. The reactor includes a generally cylindrical housing having a peripheral wall that extends between end plates. A rotor is rotatably disposed in the housing and has at least one outer peripheral surface spaced from the peripheral wall to define a cavitation zone therebetween. A plurality of bores extends through the peripheral surface of the rotor. The rotor may be formed with a central void zone between two lobes of the rotor with each lobe defining a separate cavitation zone with the peripheral wall of the housing. One or more inlet ports is arranged to introduce fluid to the housing tangentially and within one or more void zones. One or more exit ports is arranged to receive fluid from the housing tangentially within another void zone.
