Patent number: 8142534Abstract: In one aspect of the present invention, a filter is provided including a first layer of sheet material having a first base portion, and a plurality of first raised portions extending from the first base portion and defining a corresponding plurality of first openings through the first layer. A second layer of sheet material also has a second base portion and a plurality of second raised portions extending from the second base portion and defining a corresponding plurality of second openings through the sheet material. The second layer of sheet material is positioned adjacent the first layer of sheet material such that the first raised portions extend from the first base portion toward the second layer, and the second raised portions extend from the second base portion toward the first layer. A gas generating system and a vehicle occupant protection system utilizing the filter are also described.Type: GrantFiled: December 20, 2007Date of Patent: March 27, 2012Assignee: TK Holdings, Inc.Inventors: David S.

Patent number: 8142545Abstract: Embodiments of the invention include a dust extraction system including an array of two or more centrifugal dust removal devices, e.g., axial cyclones. The array of axial cyclones is configured to operate in parallel. The array of axial cyclones includes one or more sensor and a controller in communication with the sensor and adapted to receive air flow information from the one or more sensor. Inflow valves are operatively connected to the controller such that air flow through the array of axial cyclones is monitored and maintained at an optimum operating condition for each of the individual cyclones in the array. This is done, in general, by opening inflow valves as the air flow increases above a predetermined air flow value and shutting inflow valves as air flow decreases below the predetermined air flow value threshold.Type: GrantFiled: May 15, 2007Date of Patent: March 27, 2012Assignee: Federal Signal CorporationInventor: Daniel P. Strauser

Patent number: 8142553Abstract: The present disclosure provides a method and apparatus for removing debris from an air cleaner of an internal combustion engine. The method includes receiving a flow of air from a source of air flow associated with an internal combustion engine at a first end portion of a conduit and passing the flow of air towards a second end portion of the conduit. The method also includes passing the flow of air into a scavenging conduit of the air cleaner towards an exhaust end of the scavenging conduit and creating a suction pressure at an end of the scavenging conduit connected to the air cleaner. The suction pressure results in a drawing in of the debris from the air cleaner.Type: GrantFiled: October 13, 2009Date of Patent: March 27, 2012Assignee: Caterpillar Inc.Inventors: Xiaoming Tan, Mehdi M. Daragheh

Patent number: 8137434Abstract: A first intake air control mode of setting an intake throttle valve to (or close to) a fully-opened state and setting an EGR valve to (or close to) a fully-closed state is performed when DPF temperature and a particulate matter deposition quantity are greater than corresponding predetermined values respectively, a no-injection operation state exists, and engine rotation speed is higher than a corresponding predetermined value. A second intake air control mode of setting the intake throttle valve to (or close to) a fully-closed state and setting the EGR valve to (or close to) a fully-opened state is performed when the DPF temperature and the particulate matter deposition quantity are greater than the corresponding predetermined values respectively, the no-injection operation state exists, and the engine rotation speed is lower than the corresponding predetermined value.Type: GrantFiled: December 30, 2008Date of Patent: March 20, 2012Assignee: Denso CorporationInventors: Shigeto Yahata, Tsutomu Soga, Tsukasa Kuboshima

Patent number: 8137424Abstract: An air cleaner device that has a reduced size achieved by curving an air introduction path, that has a cleaner element with extended service life, and in which air flows uniformly in a clean chamber. The air introduction path (21) having an exit (21o) open to a dust chamber (12) of an air cleaner chamber (11) of an air cleaner (10) has a bent path partitioned by a flow regulation plate (22) into an inside branch path (23) inside the curve and an outside branch path (24) outside the curve. Airflows separately flowing into the dust chamber (12) from the exit (21o) after passing through the inside and outside branch paths (23, 24) are deflected upward and directed toward the cleaner element (F) by a first deflection section (33) and a second deflection section (34) arranged in the dust chamber (12). The second deflection section (34) is located at a position closer in the front-rear direction to the exit (21o) than the first deflection section (33).Type: GrantFiled: August 12, 2008Date of Patent: March 20, 2012Assignee: Honda Motor Co., Ltd.Inventor: Miyuki Ohzono

Patent number: 8137425Abstract: An intake system (10, 20) for a vehicle internal combustion engine is provided in which a first air intake duct (16), having an air intake inlet (16a) to inhale external air, is connected to an air cleaner box (14). A second air intake duct (17, 27) is also connected to the air cleaner box. The air intake inlet is closer to the air cleaner box than the second air intake duct is. The cross section area of a second air intake duct is greater than the cross section area of the first air intake duct. The center axis of the second air intake duct at an end on the side of a second air intake opening (12, 22) intersects with the center axis of the first air intake duct at an end on the side of a first air intake opening (11).Type: GrantFiled: January 29, 2008Date of Patent: March 20, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Haruhiko Saito, Tatsuya Oyama
