20100269692 | Clean corona gas ionization for static charge neutralization - Clean corona gas ionization by separating contaminant byproducts from corona generated ions includes establishing a non-ionized gas stream having a pressure and flowing in a downstream direction, establishing a plasma region of ions and contaminant byproducts in which the pressure is sufficiently lower than the pressure of the non-ionized gas stream to prevent at least a substantial portion of the byproducts from migrating into the non-ionized gas stream, and applying an electric field to the plasma region sufficient to induce at least a substantial portion of the ions to migrate into the non-ionized gas stream. | 10-28-2010 |
20110095200 | Covering wide areas with ionized gas streams - Ion delivery manifolds with a gas transport channel, for receiving an ionized gas stream, and plural outlets that divide the gas stream into plural neutralization gas streams that are directed toward respective plural target regions are disclosed. At least generally equal ion distribution across the target regions is achieved by using different ion flow rates through the plural outlets. Methods of delivering plural neutralization streams to respective plural target regions include steps for receiving an ionized gas stream, for dividing the ionized gas stream into plural neutralization streams, and for directing the neutralization streams toward respective target regions. At least generally equal ion distribution across the target regions is achieved by differing the ion flow rates of the neutralization streams. | 04-28-2011 |

20130175459 | MULTI-SECTIONAL LINEAR IONIZING BAR AND IONIZATION CELL - A multi-sectional linear ionizing bar with at least four elements is disclosed. First, disclosed bars may include at least one ionization cell with at least one axis-defining linear ion emitter for establishing an ion cloud along the length thereof. Second, disclosed bars may include at least one reference electrode. Third, disclosed bars may include a manifold for receiving gas or air from a source and for delivering same past the linear emitter(s) such that substantially none of the gas/air flows into the ion cloud. Fourth, disclosed bars may include means for receiving the ionizing voltage and for delivering same to the linear emitter(s) to thereby establish the ion cloud. In this way, disclosed ionizing bars may transport ions from the plasma region toward a charge neutralization target without inducing substantial vibration of the linear emitter and without substantial contaminants from the gas/air flow reaching the linear emitter. | 07-11-2013 |

20150250044 | LINEAR IONIZING BAR WITH CONFIGURABLE NOZZLES - Ionizing bars for delivering charged carriers to charge neutralization target objects may include an ion emitter for establishing an ion cloud of charge carriers in response to application of an ionizing voltage. Disclosed bars may also include a reference electrode that presents a non-ionizing electric field to urge ions to move away from the ion emitter. The disclosed bars may also include a manifold. The manifold may receive and divide gas into plural gas streams directed past the ion emitter in a pattern to thereby urge charge carriers toward the target. The manifold may have plural apertures with nozzled inserts received therein. At least some of the inserts may have at least one aperture through which gas may flow and the nozzle inserts may collectively direct the divided gas streams away from the manifold and toward the target in one or more predetermined patterns. | 09-03-2015 |
