Patent number: 7150773Abstract: A liquid device for extracting liquids entrained in gasses flowing through a pipeline consists of a housing having a separation and collection chamber for the extracted liquids and a flow through passage for the gasses being dried. As the gasses flow into an extractor insert, they first flow through a diffuser which aligns the gas flow and reduces the pressure in the flow. As the gasses hit the concave end of the extractor insert they are forced into a spiraling flow within the insert. The combination of reduced pressure and the spin cause any entrained liquids to be spun out of the gas flow. Both the gas and the liquids them pass through apertures in the lower surface of the extractor insert, with the liquids dropping into the collection chamber for later evacuation, while the gasses rise to an outlet port which exits to the pipeline.Type: GrantFiled: April 10, 2006Date of Patent: December 19, 2006Inventor: Bobby G.

Patent number: 7044999Abstract: An oil separator usable with a welder and air compressor combination unit. The oil separator includes a cylindrical housing having an inlet that receives the stream of compressed air containing oil from the air compressor. Within the oil separator, there is a deflector baffle that redirects the flow of the oil to a swirling, downwardly directed path along the inner surface of the cylindrical housing where the air is separated out therefrom and passes upwardly to exit through a fluid outlet formed in the cover of the separator. The swirling oil flows downwardly through an annular slot formed between a circular plate and the inner surface of the cylindrical housing into a lower chamber where the oil is channeled by radially directed baffles into radial channels to redirect that oil toward an oil outlet at the center of the circular bottom where that oil exits to be re-circulated in the combination unit or for disposal.Type: GrantFiled: March 22, 2004Date of Patent: May 16, 2006Assignee: Illinois Tools Works Inc.Inventors: Herbert A. Bankstahl, Joseph Gitter

Patent number: 6977004Abstract: A vapor-liquid separator includes an outer tube, an introduction tube, a delivery tube, and a discharge tube. The introduction tube allows passage of a vapor-liquid two-phase fluid in a swirling state. The delivery tube allows passage of the vapor phase separated from the vapor-liquid two-phase fluid. The introduction tube and the delivery tube are coaxially provided at the corresponding axially opposite ends of the outer tube. The discharge tube is provided on the outer tube in the vicinity of the axial end face of the outer tube on the side toward the introduction tube. The discharge tube is adapted to discharge therefrom the liquid phase separated from the vapor-liquid two-phase fluid. An outlet of the introduction tube and a delivery port of the delivery tube are located axially inside the outer tube by respectively predetermined axial distances while facing each other with a predetermined axial distance therebetween.Type: GrantFiled: December 24, 2002Date of Patent: December 20, 2005Assignee: Maruyasu Industries Co. Ltd.Inventors: Yasufumi Sakakibara, Haruhiko Kamino

Patent number: 6936085Abstract: A specially arranged vacuum loader and industrial dust collector with a perforated plate tangential cyclone separator is provided to efficiently remove, readily collect, effectively separate and safely dispose of wet, dry and fibrous materials, including liquids and slurries. The special vacuum loader and industrial dust collector has a solids-gas separation compartment comprising a tangential cyclone separator, preferably a perforated plate tangential separator, which is positioned generally alongside and laterally offset from one or more filtering compartments to minimize turbulence and re-entrainment of the collected particulate material.Type: GrantFiled: March 17, 2003Date of Patent: August 30, 2005Assignee: DeMarco Maxvac CorporationInventor: Thomas M. DeMarco

Patent number: 6929670Abstract: An apparatus for the separation of sand from an air stream in a thermal sand removal oven is disclosed. The preferred embodiment of the apparatus comprises a plurality of members comprising two planar members joined to form “V” shaped members. The vertex of the “V” shape points generally in the direction of the air current. The apparatus is installed in the recirculated air stream of a thermal sand removal oven, in a location between the sand molds and the air circulation means. The present invention is also installed in ovens containing metal castings containing sand cores, and ovens containing metal castings both encased in a sand mold and containing a sand core.Type: GrantFiled: January 25, 2002Date of Patent: August 16, 2005Assignee: Can-Eng Furnaces Ltd.Inventors: Mohamed S. Hamed, Alan Van Geyn

Patent number: 6896719Abstract: A dirt collecting system for a vacuum cleaner includes a dirt cup formed from a cylindrical sidewall having a disc shaped member separating the dirt cup into an upper portion and a lower portion. The dirty airstream flows past the disc shaped member from the upper portion to the lower portion through a small gap between the outer periphery of the disc shaped member and the sidewall of the dirt cup. The disc shaped member is supported on a centrally located conduit which has apertured walls located both above and below the disc shaped member. The apertured walls allows the airstream to flow into the conduit for further filtering or exiting the dirt cup. The apertured wall located above the disc shaped member improves sustained performance by enabling the airstream to continue to flow through the dirt cup as the lower portion of the dirt cup fills with large dirt particles and the apertured wall located beneath the disc shaped member becomes increasingly restricted.Type: GrantFiled: September 26, 2002Date of Patent: May 24, 2005Assignee: The Hoover CompanyInventors: Donald A. Coates, Steven W. Blate
