Patent number: 9661725Abstract: Methods and apparatus for cleaning contaminant byproducts off of ionizing wire electrodes in ionizing blowers are disclosed. Disclosed apparatus include a housing with a gas-flow channel, an stationary ionizing wire, and a rotatable frame with supports for resiliently supporting the stationary ionizing wire within the channel. The ionizing wire produces charge carriers and has a surface that develops a layer of contaminant byproducts when an ionizing signal is applied thereto. The frame is rotatably mounted such that the supports clean the layer of contaminant byproducts off of the surface of the ionizing wire when the frame is rotated. Disclosed methods include providing an ionizing signal to the ionizing wire to thereby produce charge carriers and rotating the frame relative to the housing to thereby clean contaminant byproducts off of the ionizing wire.Type: GrantFiled: May 20, 2014Date of Patent: May 23, 2017Assignee: Illinois Tool Works Inc.Inventors: Peter Gefter, Aleksey Klochkov, Leslie W.

Patent number: 8710456Abstract: 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.Type: GrantFiled: July 22, 2013Date of Patent: April 29, 2014Assignee: Illinois Tool Works Inc.Inventors: Aleksey Klochkov, Peter Gefter, Steven Bernard Heymann, Leslie W.

Patent number: 6118645Abstract: An air ionizing apparatus that produces both positive and negative ions has a housing with air inlet and outlet passages, a plurality of spaced apart air ionizing electrodes and a high voltage supply which applies positive and negative voltages to separate electrodes. A fan creates an airflow that carries the ions out of the housing, the fan preferably being between the electrodes and the outlet passages to promote intermixing of positive and negative ions.Type: GrantFiled: April 6, 1995Date of Patent: September 12, 2000Assignee: Ion Systems, Inc.Inventor: Leslie W.

Patent number: 6002573Abstract: An air ionizer comprises at least two electrodes contained within a recessed region of an insulating housing. When high voltages are applied to the electrodes, nearby air molecules are ionized and generally move towards a target region outside the housing. Because the insulating housing shields the electrodes, the production of ions is not significantly disturbed by charged or grounded objects other than those in the general direction of the target region. In one embodiment, the electrodes are placed close enough to the inner walls of the recessed region that the portions of the surfaces of the walls near the electrodes are electrostatically charged. This charge tends to repel the nearby ions, expelling many from the recessed region towards the target region.Type: GrantFiled: January 14, 1998Date of Patent: December 14, 1999Assignee: Ion Systems, Inc.Inventor: Leslie W.

Patent number: 5539631Abstract: A voltage converter circuit uses a silicon-controlled rectifier for converting input voltage to selected levels of output voltage. The silicon-controlled rectifier is connected in a circuit including a capacitor which oscillates between charging and discharging to produce a resulting waveform that is applied to a transformer for developing high positive and negative output voltages. Pulses are produced which are asynchronous with alternating line signal. Since the silicon-controlled rectifier operates on DC voltages, an electrolytic capacitor of high capacitance values can be connected between the silicon-controlled rectifier and AC or DC supply lines to substantially reduce noise signals conducted back into the supply line.Type: GrantFiled: June 16, 1994Date of Patent: July 23, 1996Assignee: Ion Systems IncorporatedInventor: Leslie W.
