Patent number: 6599348Abstract: Methods are provided for the reduction in entrainment of solids and liquids, and loss of valuable chemicals such as catalysts, in processing and refining sequences that employ separation devices in which non-vapors are to be separated from vapors. The methods comprise regulating the velocities of the incoming stream and the vapor being separated, and creating and maintaining the flow of the incoming stream tangentially to the inner surface of the separation vessel, so as to aid in the reduction in entrainment and loss of valuable chemicals.Type: GrantFiled: June 1, 2001Date of Patent: July 29, 2003Assignee: Celanese International CorporationInventors: Jack Chosnek, David William Ford, Michael B. Lakin

Patent number: 6471751Abstract: A vacuum collector is provided comprising a suction hose, a first drum with a cover having a cylindrical head capable of generating powerful, small-diameter cyclones, a second drum capable of generating large-diameter cyclones, and a stack of three modules containing vacuum-producing motors atop a HEPA filter atop primary filters. The suction hose is connected to the inlet of the small-diameter cyclone-generating head on the cover of the first drum. The stack of modules containing motors, HEPA filter, and primary filters is mounted on the second drum. The two cyclonic drums communicate through a flexible vacuum hose. When the vacuum-producing motors pull air from the interior of the vacuum collector, the suction hose sucks atmospheric air mixed with contaminants from a surface into the head, which spins the contaminant-laden air-stream into a powerful, small-diameter cyclone.Type: GrantFiled: September 11, 2000Date of Patent: October 29, 2002Assignee: Houston Industrial CorporationInventors: Stavros Semanderes, John M. Lunardini

Patent number: 6436161Abstract: Provided herein is a granular filtration apparatus for the removal of particulate material from hot gas by contacting said hot gas with granular filtration material. The apparatus being of the type having a filtration chamber containing granular filtration material and having a tapered lower portion comprising at least one inlet tubing for feeding therein hot gases to be filtered and at least one outlet tubing for drawing filtered hot gas. The main feature of the present invention consists in a filtration unit mounted in the filtration chamber above each inlet tubing. The filtration unit comprising a first tubular member mounted above the inlet tubing so as to prevent granular material from entering or blocking said inlet tubing and a second tubular member having a bottom and a top end and being mounted essentially in a co-axial and spaced relationship above the first tubular member.Type: GrantFiled: October 5, 2001Date of Patent: August 20, 2002Assignee: Kemestrie Inc.Inventors: Nicolas Abatzoglou, Jacques Bureau, Aca Mincic, Esteban Chornet

Patent number: 6395048Abstract: The invention is an inlet device or snow valve adapted to fit an air cleaner housing for a motor vehicle. The inlet device has an annular door with an open window that rotates between first and second positions. In the first position, the window of the annular door aligns with an outside air opening in the housing to allow the flow of outside air into the air cleaner apparatus. In the second position, the annular door rotates so the sidewall of the annular door covers the outside air opening and blocks the flow of outside air into the air cleaner apparatus. The second position allows the flow of under hood air into the air cleaner apparatus. In either position, the device preferably totally closes the other opening to assure all under hood intake air flow comes from the desired location.Type: GrantFiled: August 30, 2000Date of Patent: May 28, 2002Assignee: International Truck Intellectual Property Company, L.L.C.Inventors: Lamar D. Yoder, Gerald J. Nix
