Patent number: 6814783Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.Type: GrantFiled: March 14, 2003Date of Patent: November 9, 2004Assignee: Phillips Plastics CorporationInventors: Tom Fitch, Majid Entezarian, James R.

Patent number: 6699310Abstract: An HC adsorbing sheet inside an air cleaner is disposed such that a large amount of activated carbon is contained on the side of an engine and that a small amount of activated carbon is contained on the other side of the engine. Thus, the HC adsorbing sheet can efficiently adsorb evaporative fuel. That is, by changing the amount of activated carbon contained in accordance with differences in concentration of evaporative fuel, it becomes possible to prevent the pressure loss in an intake system from increasing. On the other hand, one end of a second intake pipe extends to a region where the amount of activated carbon contained in the HC adsorbing sheet is large, whereby it becomes possible to concentratively supply activated carbon with intake air in the region where the large amount of activated carbon is contained. Therefore, the efficiency in purging evaporative fuel can be prevented from declining.Type: GrantFiled: December 16, 2002Date of Patent: March 2, 2004Assignees: Toyoda Boshoku Corporation, Nippon Soken, Inc.Inventors: Kouichi Oda, Takanobu Kawano, Masaki Takeyama, Naoya Kato

In order to permit the wearer to rotationally position the color-changing display field in the line of sight through the transparent portion of the respirator facepiece, the cartridge is provided with a rotatable mounting assembly that is continuously rotatable in one direction and that forms a seal with the cartridge shell.Type: GrantFiled: September 12, 2000Date of Patent: December 24, 2002Assignee: North Safety Products, Inc.Inventors: Len Curado, Edna M. deMedeiros

Publication number: 20020189459Abstract: An isolation mechanism is provided for a trailer air dryer to limit transfer of forces from a trailer frame to the dryer. In a first embodiment, elastomeric bushings are interposed between the trailer frame and the dryer to reduce the forces transferred to end covers of the trailer dryer. In another embodiment, the mounting assembly is modified to include a connection directly to a central body of the air dryer. In yet another embodiment, U-shaped fasteners couple the body of the air dryer to the frame.Type: ApplicationFiled: June 13, 2001Publication date: December 19, 2002Applicant: Honeywell Commercial Vehicle Systems CompanyInventors: Fred Hoffman, Leonard Quinn, James Koenig

Publication number: 20020170437Abstract: A venting device that reduces the moisture of an enclosure containing a heat source and prevents the entrance of water or other liquids and contamination from entering the enclosure. The moisture reducing device comprises a drying agent or desiccant which is adjacent to said heat source (such as an automotive headlamp bulb or thermally cycling device), an air-impermeable, water-vapor permeable layer, a vent that allows bulk flow of air during thermal cycling of the heat source and a internal diffusion tube or channel that limits the entrance of moisture vapor from the external atmosphere to the drying agent or desiccant. The air-impermeable, water vapor permeable layer allows for continuous diffusion of water vapor, reducing the moisture in the enclosure when the heat source is de-energized. The location of the device to the heat source regenerates the drying agent in the device when the heat source is energized.Type: ApplicationFiled: March 25, 2002Publication date: November 21, 2002Inventors: David T. DeGuiseppi, Kerry L. DeWitt, Amy Elizabeth Johnson

Patent number: 6475270Abstract: A diffusion channel assembly for use with a device enclosure with two or more nested cups forming at least one diffusion channel. The nested cups are formed of a thermoplastic film material. Each of the cups has a perimeter seal portion substantially around the entire outer perimeter of the cups and surrounding a cup portion having a vent hole. The perimeter seal portions form a sealing surface and are generally integral with the cup portions. The cup portions have vent holes and at least one gap between adjacent cup portions that connect the vent holes of the adjacent cup portions. The gaps coupled with the vent holes of adjacent cup portions form at least one diffusion channel of a length of at least 5 mm. The perimeter seal portions are sealed to form an airtight seal around the cup portion forming an integral diffusion channel assembly.Type: GrantFiled: May 22, 2000Date of Patent: November 5, 2002Assignee: 3M Innovative Properties CompanyInventor: Eric G. Graeve

Patent number: 6471755Abstract: A gas conducting system, particularly a compressed air system for a motor vehicle, which includes a filter containing a desiccant for removing moisture from a gas passed therethrough. The housing structure of the filter is provided with a seal with a weakened area 18, which specifically causes any overpressure to be reduced through failure of the weakened area if the pressure inside exceeds a permissible maximum. This process can be repeated multiple times until the seal with the weakened area 18 must be replaced due to aging. The weakened area can be used as a substitute for a pressure relief valve or as supplemental protection in case the pressure control valve fails, e.g., due to ice. This can prevent, for instance, bursting of the filter housing which could present a safety risk.Type: GrantFiled: August 9, 2001Date of Patent: October 29, 2002Assignee: Filterwerk Mann & Hummel GmbHInventors: Walter Binder, Markus Kolczyk, Christian Fischer

Patent number: 6468334Abstract: An elongated adsorbent unit for use in combination with an elongated refrigerant-containing housing includes a housing having first and second ends, and an interior and an exterior. Adsorbent is compacted in the interior of the housing. First and second porous end members are secured to the first and second ends of the housing, respectively. One or more fluid communication channels extend along the exterior of the housing between the first and second ends of the housing.Type: GrantFiled: January 2, 2001Date of Patent: October 22, 2002Assignee: Multisorb Technologies, Inc.Inventors: Samuel A. Incorvia, Rodney L. Dobson, Leo J. Schwartz

Patent number: 6454837Abstract: Gas mixtures of SF6 and N2, which have been used, for example, as an insulating filler gas for underground cables, for insulating-gas window panes or as a filler gas for car tires and SF6/air mixtures which have been used as a protective gas when casting magnesium can be separated if they are contacted with hydrophobic zeolites of a certain pore size as selective adsorption agent for sulfur hexafluoride. For a relatively high SF6 concentration, the mixture is preferably first subjected to a membrane separation process and the permeate is contacted with the adsorption agent. The invention also relates to an apparatus for carrying out the process. The process may also be used for separating SF6 from exhaust gases.Type: GrantFiled: February 20, 2001Date of Patent: September 24, 2002Assignee: Solvay Fluor und Derivate GmbHInventors: Michael Pittroff, Thomas Schwarze, Heinz-Joachim Belt, Pierre Barthélemy
