Abstract: A corona discharge static neutralizing device includes a wire electrode retained in tension between spaced ends of a resilient support member that is positioned within a flowing air stream. Another electrode aligned with and spaced from the wire electrode promotes a flowing ion stream, when connected to receive an ionizing difference of potential, that flows in skew orientation relative to the flowing air stream. Multiple wire electrodes are supported in tension on a resilient support member along with another electrode disposed on the support member intermediate the wire electrodes and in substantially the same plane therewith.

Abstract: An air ion collimator is added to ionizers with integrated fans that are used to remove static charge. Three mechanisms minimize air ion losses through recombination. Hence, the collimator increases the air ions that are available for charge removal. First, reducing turbulence slows air ion mixing. Second, air entrainment into fast moving air ion zones further slows the rate of air ion losses by dilution. The rate of recombination reaction slows with decreasing ion density. Third, vanes within the collimator delay mixing. In addition to conserving air ions, the collimator directs more ions to the target. Air ions lost to grounding are reduced. Again, more air ions are available to remove static charge from the target.

Abstract: An ionizer bar includes upper and lower housings having aerodynamically-shaped exterior surfaces to support laminar air flow over the structure. The upper housing forms an upper interior chamber for electrical circuitry isolated from a lower chamber within the lower housing that confines fluid under pressure therein. Outlets spaced along the length of the structure include ionizing electrodes that are disposed within fluid conduits and that are connected to a source of ionizing voltage mounted in the upper chamber. Fluid passages at the outlets release fluid under pressure within the lower chamber around associated ionizing electrodes mounted at the outlets.

Abstract: A first stream of pressurized gas is directed at high toward a target area through an ionization chamber. As the high-speed, pressurized gas flows through the ionization chamber, a low-pressure region is used to draw a second stream of gas into the ionization chamber. The second stream of gas is drawn into the ionization chamber from the target area. Re-circulation of gas from the target area supplements the pressurized gas, thereby increasing the efficiency of ionization while reducing the volume of pressurized gas that must be consumed. This helps to prevent recombination while increasing the rate of flow of ionized gas to the target area. A cost-effective, safe, low-level radiation source is used to direct soft X-rays through a filtering window at the gas as it passes through the ionization chamber. Use of the filtering window physically separates the low-level radiation source from the ionization chamber and only allows soft X-rays to pass into the chamber.
