  • Publication number: 20140151938
    Abstract: The disclosed technology includes systems and methods for clustering particles, especially water contaminants, by liquid-phase electric plasma discharge. According to certain implementations, the discharge may be applied continuously, and may be of relatively low power, e.g., a voltage between 300 V and 5000 V and an amperage between 0.1 A and 1 A. The electrodes introducing the electric discharge may be in a point-to-point configuration and with at least one electrode having a large aspect ratio. In some implementations, one or more of the voltage and amperage of the electric discharge, electrode configuration and aspect ratio, and the conductivity of the medium may enable the generation of plasma containing hydroxyl and other radicals. The radicals may catalyze polymerization of the particles, resulting in an increase in particle size and, thus, improved filterability. The polymerization process may continue after the electric discharge is discontinued or removed from influence of the medium.

  • Publication number: 20120292828
    Abstract: Disclosed is a method of manufacturing a composite sheet. The method comprises (a) irradiating a sheet of fibres and a matrix film at an irradiation zone with a plasma at substantially atmospheric pressure, and (b) impregnating the sheet of fibres with the matrix at an adhesion zone. The processes (a) and (b) are performed simultaneously, and the matrix film is irradiated with a plasma at said irradiation zone after being unwound from a roller and prior to entering said adhesion zone.

  • Publication number: 20120273188
    Abstract: A method of forming a swellable oilfield apparatus provides an apparatus with a body of swellable elastomeric material which increases in volume on exposure to at least one triggering fluid, and the surface energy of the swellable elastomeric material is modified to increase the water-wettability of the swellable elastomeric material. The swellable elastomeric material may comprise a base elastomer and at least one additive selected to modify the surface energy. Alternately, the swellable elastomeric material may comprise a base elastomer treated by an electrical treatment process to modify the surface energy of the swellable elastomeric material. An apparatus constructed according to the method provides improved swelling performance in aqueous fluids.

  • Publication number: 20120263422
    Abstract: A method for processing ferrules for fiber optic connectors is disclosed herein. The method involves ablating a distal end face of the ferrule with the plurality of laser beam pulses to remove a distal layer of the ferrule without removing an optical fiber secured within the ferrule. By removing the distal layer from the ferrule, the optical fiber is caused to protrude distally outwardly from the distal end of the ferrule by a desired amount.
