  • Patent number: 8899127
    Abstract: The present invention discloses a safety trigger mechanism and functional frame for motion furniture for driving a drive mechanism of motion furniture. The safety trigger mechanism includes a mounting board, and a pull wire, a fork and a first restoring spring connected in turn. The fork is mounted turnably about a first rivet on the mounting board by the first rivet, and a bent hook is disposed on one end of the fork and interlocked with a driving arm of the drive mechanism. The safety trigger mechanism further includes a safety hook with a notch, which is mounted turnably about a second rivet on the mounting board by the second rivet. One side edge of the safety hook abuts against the bent hook of the fork, and the driving arm has an arresting pin disposed thereon. The initial position of the arresting pin is in the notch of the safety hook, and the arresting pin is detached from the notch of the safety hook when the safety hook turns clockwise.

  • Patent number: 7011790
    Abstract: A method and apparatus are provided for at least partially disinfecting biological fluid of a mammal, which comprises pathogens in addition to normal cellular fractions. The method includes placing the biological fluid in a reaction volume and contacting a non-thermal plasma with the biological fluid to thereby kill at least a portion of the pathogens within the biological fluid.

  • Patent number: 6911225
    Abstract: A non-thermal plasma reactor is provided for treating a liquid with non-thermal plasma species. The reactor includes a liquid inlet, a liquid outlet, a reaction volume between the liquid inlet and the liquid outlet and at least one non-thermal plasma electrode adjacent to the reaction volume. The non-thermal plasma electrode is isolated physically and electrically from the flow path by a dielectric barrier.

  • Patent number: 6565716
    Abstract: A dielectric barrier discharge system includes first and second non-thermal plasma reactors which are coupled together in series. The first reactor includes a first surface discharge electrode which defines a first discharge path along the first surface discharge electrode. The second reactor includes second and third electrodes which are separated by a gap and define a second discharge path which extends across the gap. The system can be used to decompose hazardous compounds in a liquid or a gas, such as in power plant flue gases.

  • Patent number: 6562386
    Abstract: A method and apparatus are provided for at least partially sterilizing a liquid that has pathogens living in the liquid. The liquid comprising living pathogens is placed in a reaction volume, and a non-thermal plasma is generated within the reaction volume to thereby kill at least a portion of the pathogens within the liquid.
