  • Patent number: 10005682
    Abstract: A system is described herein which provides an ozonated liquid. The system comprises a liquid inlet arranged to continuously accept a liquid into the system at a desired flow rate; a liquid outlet to dispense ozonated liquid out of the system, the ozonated liquid having an oxidation-reduction potential of at least 450 mV due solely to ozone dissolved in the liquid, the liquid outlet being in fluid communication with the liquid inlet and arranged to dispense the ozonated liquid out of the system at the desired flow rate. The system has a tank-less ozonation flow path between the liquid inlet and the liquid outlet, the flow path adapted to ozonate the accepted liquid, producing the ozonated liquid to be dispensed out of the system. The accepted liquid has a fluid residence time in the ozonation flow path of less than 5 minutes prior to being dispensed as the ozonated liquid.

  • Patent number: 9987605
    Abstract: Continuous, three-dimensional control of the vorticity vector is possible by progressively transitioning the field symmetry by applying or removing a dc bias along one of the principal axes of mutually orthogonal alternating fields. By exploiting this transition, the vorticity vector can be oriented in a wide range of directions that comprise all three spatial dimensions. Detuning one or more field components to create phase modulation causes the vorticity vector to trace out complex orbits of a wide variety, creating very robust multiaxial stirring. This multiaxial, non-contact stirring is particularly attractive for applications where the fluid volume has complex boundaries, or is congested.

  • Patent number: 9339821
    Abstract: An apparatus is disclosed for separating minerals in drilling fluid based primarily on density. The separator creates and maintains a slurry with a controllable density for separating minerals from drill cuttings. The density is controlled through the use of an electrode array. The separator comprises a primary separation chamber containing the dense slurry, and a multiple number of secondary separation chambers used to separate cuttings from the drilling fluid. The invention also contains inlet hardware allowing the mixed mineral suspension to enter the first separation chamber, and hardware allowing the three outlet (separated) streams to exit the device. One of the three outlet streams carries the minerals that have a density greater than the user selectable density set point, while the second carries the minerals that have a density less than the density set point, and the third carries clean drilling fluid.

  • Publication number: 20150147560
    Abstract: A method for alignment of high aspect ratio materials (HARMs) within a liquid matrix by means of magnetic particles. The application of an external magnetic field creates a forced motion of the magnetic particles. This in turn leads to a laminar flow within the matrix which imposes a drag force on the HARMs, aligning the HARMs across the matrix. The used magnetic particles eventually accumulate at one end side of the matrix container and can be removed either by an incision or an extraction process. Unlike the previously proposed methods, there is no need for the magnetic particles to be attached either physically or chemically to the HARMs. Thus, the ultimate aligned HARMs are mostly pure and free of any magnetic particles. Once the matrix is a polymeric solution, the mentioned method is capable of synthesis of aligned HARMs-polymer composites, which exhibit improved mechanical and electrical properties.

  • Patent number: 8057686
    Abstract: A nanotube separation method includes depositing a tag on a nanotube in a nanotube mixture. The nanotube has a defect and the tag deposits at the defect where a deposition rate is greater than on another nanotube in the mixture lacking the defect. The method includes removing the tagged nanotube from the mixture by using the tag. As one option, the tag may contain a ferromagnetic material and the removing may include applying a magnetic field. As another option, the tag may contain an ionic material and the removing may include applying an electric field. As a further option, the tag may contain an atom having an atomic mass greater than the atomic mass of carbon and the removing may include applying a centrifugal force to the nanotube mixture. Any two or more of the indicated removal techniques may be combined.

  • Patent number: 8043486
    Abstract: A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis.

  • Patent number: 8034245
    Abstract: The present invention provides a method of driving liquid flow at or near a free surface using self-assembled structures composed of magnetic particles subjected to an external AC magnetic field. A plurality of magnetic particles are supported at or near a free surface of liquid by surface tension or buoyancy force. An AC magnetic field traverses the free surface and dipole-dipole interaction between particles produces in self-assembled snake structures which oscillate at the frequency of the traverse AC magnetic field. The snake structures independently move across the free surface and may merge with other snake structures or break up and coalesce into additional snake structures experiencing independent movement across the liquid surface. During this process, the snake structures produce asymmetric flow vortices across substantially the entirety of the free surface, effectuating liquid flow across the free surface.
