Patent number: 7879142Abstract: A cyclone dust collector includes a cyclone body including a first cyclone chamber to centrifugally separate dust from drawn-in air for a first time, a plurality of second cyclone chambers to centrifugally separate dust from the drawn-in air for a second time, and a plurality of discharge ports to cause the drawn-in air to be discharged from the plurality of second cyclone chambers; an upper cover to cover an upper portion of the cyclone body, the upper cover having an inner wall facing the plurality of discharge ports; and a noise reduction part disposed between the plurality of discharge ports and the inner wall of the upper cover, to reduce noise generated inside the upper cover by the air discharged through the plurality of discharge ports. Therefore, it is possible to reduce noise generated inside the upper cover of the cyclone dust collector.Type: GrantFiled: June 5, 2008Date of Patent: February 1, 2011Assignee: Samsung Gwangju Electronics Co., Ltd.Inventors: Jung-gyun Han, Joung-soo Park, Byung-jo Lee, Tae-gwang Kim, See-hyun Kim

Patent number: 7789921Abstract: Portable devices for mitigating the accumulation and localized settling of airborne particulates are provided. The devices establish airflow patterns which push or carry various airborne particulates outwardly away therefrom, thereby establishing a localized zone having relatively fewer airborne particulates. Correspondingly, each the devices establishes a localized zone, defined circumferentially about the perimeter of the device, in which there is relatively less surface accumulation of particulates which were previously airborne and settled out. The devices establish such airflow patterns by proving a fan which draws a volume of air axially through a top portion of the device, then pushes the volume of air axially down through the device where it is radially emitted from the bottom portion of the device, defining a circumferentially expanding plane of airflow.Type: GrantFiled: May 29, 2007Date of Patent: September 7, 2010Assignee: S.C. Johnson & Son, Inc.Inventors: Matthew N. Thurin, Michael J. Maloney, Jeremy F. Knopow, Kevin L. Askling, René Maurice Béland

Patent number: 7763090Abstract: A cyclonic separating apparatus includes a chamber for separating dirt and dust from an airflow, an inlet to the chamber and a shroud. The shroud includes a wall having inner and outer surfaces and a multiplicity of through-holes forming an outlet from the chamber. Each through-hole has an axis. The inner surface of the wall has a serrated profile having a plurality of serrations arranged around at least a part of the circumference of the wall, each serration having a first face and a second face. At least one through-hole passes through the first face of at least one serration. By providing a plurality of serrations around the inner circumference of the wall, the airflow is forced to follow a longer path through each through-hole for when compared to conventional arrangements. This reduces the amount of dirt and dust which is able to pass through the shroud.Type: GrantFiled: June 25, 2008Date of Patent: July 27, 2010Assignee: Dyson Technology LimitedInventors: Ricardo Gomiciaga-Pereda, James Dyson, Edward Charles Ormerod, John Lee Gruenig

Patent number: 7753977Abstract: An air filtration system includes a support structure, an enclosure coupled to the support structure and including an air outlet, a filter and a fan operatively coupled to the enclosure, and a diffusion screen configured to cover the air outlet. The diffusion screen includes a screen frame configured to be removably attachable to the enclosure with at least one releasable fastener, and at least a diffusion layer substantially spanning the screen frame to cover the air outlet to provide unidirectional or laminar air flow from the air outlet.Type: GrantFiled: June 9, 2005Date of Patent: July 13, 2010Assignee: Filtration Group, Inc.Inventors: Edward F. Lyons, Wenli Wang, Philip J. Winters

Patent number: 7713332Abstract: A carbon dioxide separation system for a fuel cell system having a small volume and weight of a separation device and of a membrane, at simultaneous increase of the separated volume of carbon dioxide, comprises a separation device for containing a fluid phase, a carbon dioxide phase, and a two phase fluid including fluid and carbon dioxide. The separation device comprises a two phase fluid inlet, a fluid outlet, a carbon dioxide outlet, a carbon dioxide separation membrane, and a flow restrictor creating a backpressure which presses separated carbon dioxide through the carbon dioxide separation membrane. The flow restrictor comprises at least one narrow aperture, and is mounted downstream of the separation device. The carbon dioxide separation membrane is positioned in the separation device in such a manner that at least a part of the total membrane area is arranged above a two phase fluid level and is in touch with carbon dioxide contained in the separation device above the two phase fluid level.Type: GrantFiled: February 2, 2007Date of Patent: May 11, 2010Assignees: Samsung SDI Co., Ltd., Samsung SDI Germany GmbHInventor: Matthias Bronold

Publication number: 20100000413Abstract: An air filtration device configured for operational association with an electrical outlet mounted on a wall includes a housing the defines a front surface, a rear surface and an air flow path therethrough. A cover is attached to the front surface of the housing in a spaced-apart relationship. The cover and the front surface of the housing define a slot. An impeller is provided for moving air through the air flow path. A motor drives the impeller. The motor and the impeller are supported within the housing. A tray is removably positionable within the slot.Type: ApplicationFiled: July 1, 2008Publication date: January 7, 2010Applicant: HAMILTON BEACH BRANDS, INC.Inventors: Mark Francis Turner, Martin Patrick Brady
