Patent number: 7097695Abstract: An air conditioner device includes a housing, a first electrode disposed in the housing, and a second electrode removably disposed in the housing. The second electrode can be manually removed from the housing and then manually returned to a resting position within the housing. A base member is attached to a bottom portion of the second electrode. An at least partially flexible cleaning member is attached to the base member. The cleaning member frictionally cleans the first electrode when, after being removed from the housing, the second electrode is manually returned to the resting position within the housing.Type: GrantFiled: September 12, 2003Date of Patent: August 29, 2006Assignee: Sharper Image CorporationInventors: Shek Fai Lau, Jimmy L. Lee, Andrew J. Parker

Patent number: 6958088Abstract: A carbon separation and collection device used for a high performance dust collector includes a water supply tube, a water pump, a high pressure negative electrode discharge device, a high pressure positive electrode discharge device, a rotary brush, a removing plate, a carbon collector, a liquid tank, and a speed change device and an exhausting tube. The two discharge devices serve to achieve a function of electrolyte. When the cleaning liquid with carbon flows into the water supply tube by using the water pump. The carbon is adhered to the high pressure positive electrode discharge device. The high pressure positive electrode discharge device is driven to rotate by the speed change device. The carbon is moved from the high pressure positive electrode discharge device by the rotary brush and removing plate. Then, the removing carbon drops into the carbon collector.Type: GrantFiled: September 27, 2004Date of Patent: October 25, 2005Inventor: Toshio Moriyama

Patent number: 6899745Abstract: An air cleaner electrode assembly includes an elongated collector electrode and a plurality of elongated discharge electrodes arranged around the collector electrode. A fan may move air in a direction parallel to a length of the electrodes. The collector electrode may have a plurality of distinct faces where at least one discharge electrode is associated with a corresponding face. A cleaning shuttle may be configured to ride on and remove debris from the elongated electrodes. A voltage differential across the electrodes and the fan speed may be adjusted independently of each other.Type: GrantFiled: October 8, 2002Date of Patent: May 31, 2005Assignee: Kaz, Inc.Inventors: Stephen M. Gatchell, Chi-Hsiang Wang

Patent number: 6899748Abstract: A method and apparatus for removing contaminants from gas streams. A first step involves selecting a contaminant to be removed from a gas stream and determining a characteristic ionizing energy value required to selectively ionize the selected contaminant with minimal effect on other contaminants in the gas stream. A second step involves applying the characteristic ionizing energy value to the gas stream and selectively ionizing the selected contaminant. A third step involves capturing the selected contaminant after ionization.Type: GrantFiled: May 28, 2004Date of Patent: May 31, 2005Inventor: Moustafa Abdel Kader Mohamed

Patent number: 6749667Abstract: An electro-kinetic electro-static air conditioner with a bead member having a bore, through which a wire-like electrode passes. The bead is moved along the wire to frictionally clean the wire-like electrode when an electrode array is removed. A bead lifting arm is mounted to the electrode array. The bead lifting arm can move the bead to clean the electrode as electrode array is removed from the air conditioner for cleaning.Type: GrantFiled: October 21, 2002Date of Patent: June 15, 2004Assignee: Sharper Image CorporationInventors: John Paul Reeves, Shek Fai Lau, Andrew J.

Patent number: 6709484Abstract: An electro-kinetic electro-static air conditioner includes a mechanism to clean the wire-like electrodes in the first electrode array. A length of flexible Mylar type sheet material projects from the base of the second electrode array towards and beyond the first electrode array. The distal end of each sheet includes a slit that engages a corresponding wire-like electrode. As a user moves the second electrode array up or down within the conditioner housing, friction between slit edges and the wire-like electrode cleans the electrode surface. The sheet material may be biasedly pivotably attached to the base of the second electrode array, and may be urged away from and parallel to the wire-like electrodes when the conditioner is in use. Another embodiment includes a bead-like member having a through opening or channel, through which the wire-like electrode passes.Type: GrantFiled: August 8, 2001Date of Patent: March 23, 2004Assignee: Sharper Image CorporationInventors: Shek Fai Lau, Jimmy Luther Lee, Andrew J.

Patent number: 6656248Abstract: The invention relates to a method to clean air for separating materials in the form of particles and/or droplets from a gas flow. The gas flow is directed through a collection in which the outer walls are grounded, and in which high voltage is supplied to the ion yield tips arranged in the collection chamber. Thus an ion beam from the ion yield tips towards collection surfaces is established to separate desired material from the gas flow. The electrically conductive collection surfaces are electrically insulated from the outer castings and high voltage is supplied to the collecting surfaces, in which the direct-current voltage has an opposite sign as the high voltage directed to the ion yield tips. The collection surface is totally conveniently and rapidly detached for clean material replacement.Type: GrantFiled: October 3, 2001Date of Patent: December 2, 2003Assignee: Moira Ltd.Inventor: Toni Niko Ilmasti

Patent number: 6558456Abstract: The present invention relates to an apparatus for controlling the behavior of particulate matter such as mist and dust occurring in the manufacture of paper and board. A web (1) is passed to web treatment equipment (22, 23) wherein at least one treatment step is applied to the web (1) causing the emission of said particulate matter (24). In the vicinity of the emission point (21) of said particulate matter are placed at least two electrodes (25, 26) and at least one electrode, called a counter-electrode (26), is at a low potential. Further, at least one electrode (25) is at a potential higher than that of said counter-electrode (26), and the potential difference between said electrodes (25, 26) is made so high as to generate a corona discharge between said electrodes that causes an ion-blast wind toward the electrode (26) of the lower potential, said ion-blast wind being capable of transferring particular matter, which enters the gap between said electrodes, toward said electrode of lower potential.Type: GrantFiled: February 11, 2002Date of Patent: May 6, 2003Assignee: Valmet CorporationInventor: Vilho Nissinen

Patent number: 6126727Abstract: An electrode panel-drawing device of a static ion discharger, including a box body. A top section of the box body is formed with an opening. A bottom section of the box body is disposed with a connecting seat. The box body is disposed with ventilators, an activating switch and an adjustment button. A motor, a fan and an AC-to-DC circuit board are disposed in the box body. A drawer body is fitted into the opening of the box body. The drawer body is disposed with discharge needles and electrode panels at equal intervals. The positive terminal of the circuit board is connected to the discharge needles, while the negative terminal of the circuit board is connected to the electrode panels. The positive discharge needles ionize the air to eliminate the static electricity. The drawer body can be drawn out of the box body for directly washing the discharge needles and the electrode panels.Type: GrantFiled: January 28, 1999Date of Patent: October 3, 2000Inventor: Ching-Hsiang Lo
