    Patent number: 5394293
    Abstract: Apparatus for ionizing a gas. The apparatus includes an ionizing generator with an insulating frame, an electrical insulator and a conductive brush formed of individual bristles. An ionizing power supply connects to the conductive frame and the electrically conductive brush. When a threshold potential is applied by the power supply, ionizing discharges emanate from the free ends of individual conductive wires in the brush and establish discharge paths with the conductive frame thereby to produce a volume of ionized gas.
