Patent number: 7261762Abstract: A method and system for detecting and predicting air filter condition for an air handling system operates by determining a system resistance to air flow. The system resistance is utilized to determine a detection statistic indicative of current filter condition and to predict remaining life of the air filter. The system resistance is determined using models that approximate the expected operation of the air handling system. The approximation is then compared to actual values to obtain a difference. Once the difference between the approximated value exceeds a threshold value, an alarm is initiated that is indicative of system resistance. The remaining air filter life is then determined by using historically gathered data, or by using a known degradation rate of the air filter. Once the remaining life of the air filter is estimated, replacement can be scheduled that would coincide with other maintenance.Type: GrantFiled: May 6, 2004Date of Patent: August 28, 2007Assignee: Carrier CorporationInventors: Pengju Kang, Mohsen Farzad, Slaven Stricevic, Payman Sadegh, Alan M.

Patent number: 7041157Abstract: An apparatus for separating and converting exhaust particulates from a stream of exhaust gas, especially a diesel engine, into gaseous substances, in which the exhaust gas is guided through a honeycomb filter (6) made from a porous ceramic material whose axially extending channels (1, 2) are open merely at one face side of the filter and are closed off at the respective other face side, and a voltage is applied to electrodes (3, 4) extending parallel to the channels (1, 2) of the honeycomb filter (6). The closure of the channels (1, 2) at the face side is made in such a way that the channels (1, 2) each extending at the same normal distance from one of the electrodes (3, 4) are either all open or all closed off at their face side (9). The channels (1, 2) are mutually offset in a brickwork-like way.Type: GrantFiled: November 9, 2000Date of Patent: May 9, 2006Inventor: Carl Maria Fleck

Patent number: 7014673Abstract: A filtering apparatus for a reflow oven includes a contaminated-gas inlet for receiving contaminated gas from a reflow oven; a filtering device configured to filter the received contaminated gas; a returned gas outlet for returning filtered gas to the reflow oven; a gas removal arrangement for allowing gas to escape from the apparatus; and a control arrangement for controlling the rate of gas flow through the gas removal arrangement such that in use the flow rate of contaminated gas flowing from a hotter region of the reflow oven to a cooler region of the reflow oven is controlled.Type: GrantFiled: October 22, 2004Date of Patent: March 21, 2006Assignee: BTU International, Inc.Inventor: Philip Arthur Mullins

Patent number: 6989048Abstract: A particulate filter for purifying exhaust gases of an internal combustion engine, in particular of a diesel engine, comprises a filtering body and heating elements for initiating combustion of soot particles accumulated on and in the filtering body. The heating elements comprise at least a hot spot ceramic ignitor (3). The invention is applicable in the automotive industry.Type: GrantFiled: October 29, 2001Date of Patent: January 24, 2006Assignee: Saint-Gobain Centre de Recherches et d'Etudes EuropeenInventors: Sébastien Bardon, Craig Willkens

Patent number: 6969413Abstract: A flow rate of gas supplied to a diesel particulate filter is increased when it is determined that rapid combustion of collected particulates, which are collected by the particulate filter, is likely to occur based on an operating state of an internal combustion engine. Alternatively, the flow rate of gas supplied to the filter is increased when it is determined that rapid combustion of the collected particulates is initiated based on a state of the particulate filter.Type: GrantFiled: June 12, 2003Date of Patent: November 29, 2005Assignee: Denso CorporationInventors: Shigeto Yahata, Makoto Saito, Tsukasa Kuboshima, Shinichiro Okugawa, Masumi Kinugawa

Patent number: 6955704Abstract: A method and mobile system for cleaning dirty gas from a newly stimulated gas well. The entire system is supported on a trailer or other mobile support so that it can be driven from well site to well site for short-term, post-stimulation use only. The system comprises a gas separator, such as a membrane separator. The system also includes a pretreatment assembly for preparing the gas for the gas separator. The pretreatment assembly may include separators, a heater, a guard vessel and a polishing filter. A chiller or heat exchanger cools the treated gas to a marketable temperature. A generator and a hydraulics plant provide power to the system. Each mobile system will be designed to treat gases with widely different operating conditions varying from well to well.Type: GrantFiled: October 28, 2003Date of Patent: October 18, 2005Inventor: Ronald L. Strahan

Patent number: 6830600Abstract: A method for preventing migration of lubrication molecules into adjacent process chambers while coating a thin layer of lubricant over a storage surface of a disc using a vapor lubrication process. The method includes trapping the lubrication molecules that are not deposited onto the storage surface of the discs during the vapor lubrication process by using one or more cold traps including cold trapping surfaces in a vapor lubrication station.Type: GrantFiled: April 12, 2001Date of Patent: December 14, 2004Assignee: Seagate Technology LLCInventors: Paul Stephen McLeod, Michael Joseph Stirniman, Jing Gui

Patent number: 6800106Abstract: A filter apparatus includes a filter panel having inner and outer surfaces and a configuration for completely covering a computer housing ventilation opening. The filter apparatus includes an adhesive layer permanently adhered to the inner surface of the filter panel. A thermochromic region is positioned on the outer surface of the filter panel which changes color as temperature increases. The thermochromic region includes an ink layer and a wax layer positioned atop the ink layer. The wax layer includes a thermochromic dye having a color different from the color of the ink layer. The color of the thermochromic dye blocks the color of the ink layer at an ambient temperature and is transparent to allow the ink layer color to be seen at an activation temperature. Therefore, the filter apparatus provides an indication when the filter is full and heat is building within the housing as a result.Type: GrantFiled: February 25, 2003Date of Patent: October 5, 2004Inventors: William K.
