The method comprises introducing a first liquid into the fluid delivery system and contacting the interior surface with the first liquid; forming a slurry by introducing a particulate into the first liquid and contacting the interior surface with the slurry; introducing a second liquid into the fluid delivery system and contacting the interior surface with the second liquid; and introducing a third liquid into the fluid delivery system and contacting the interior surface with the third liquid. The first liquid is substantially soluble or substantially insoluble in the second liquid, the second liquid is substantially insoluble in the third liquid, and the particulate is substantially insoluble in the first and second liquids and substantially soluble in the third liquid.Type: GrantFiled: October 10, 2008Date of Patent: March 22, 2011Assignee: PPG Industries Ohio, Inc.Inventors: Jonathan N. Warren, Phillip J. Beauchamp, Finn Bergishagen, Denise A. Palumbo

Publication number: 20110061681Abstract: A cleaning and obstruction locating pipeline pig according to this invention includes a magnetic nose bumper at its forward end and a disc located in the central bypass flow passageway that prevents product from flowing through the central bypass flow passageway while the pig is travelling forward in the pipeline. If debris ahead of the pig causes the pig to become stuck in the pipeline, product flow pressing upon the disc ruptures the disc, thereby allowing product to flow through the central bypass flow passageway until the pig is located and removed from the pipeline. The pig may also be used to locate a previously launched but stuck pipeline pig.Type: ApplicationFiled: September 16, 2009Publication date: March 17, 2011Inventor: Andrew Brian Cassidy

Patent number: 7896971Abstract: Methods for removing accretions of cured concrete from within a mixing drum are herein disclosed. One method includes an inserting impact tool mounted upon a boom into the interior of the mixing drum, addressing a bit of the impact tool to an accretion adhered to the inner surface of the mixing drum, and actuating the impact tool to apply a force to the accretions through the bit so as to remove the accretion from the interior surface of the mixing drum.Type: GrantFiled: June 2, 2009Date of Patent: March 1, 2011Assignee: HammerRock, Inc.Inventor: Alan E. Molter

Patent number: 7875121Abstract: A pipe maintenance method and device is particularly suited for maintaining a pipe of a gas-insulated high-voltage line with a particle trap system extending along the pipe. The novel method enables poorly accessible sections to be reached. To this end, a maintenance unit is displaced along the particle trap system, and it is guided thereby.Type: GrantFiled: July 4, 2006Date of Patent: January 25, 2011Assignee: Siemens AGInventor: Hermann Koch

Patent number: 7862660Abstract: A method for cleaning interior surfaces of a header region of a hemodialyzer includes steps of: introducing an insertion device having an end portion and a shaft through a hemodialyzer plug port so that the end portion of the insertion device is within the header region; rotating the shaft at a speed sufficient to generate mechanical stresses for the removal of contaminants from interior surfaces of the header region; removing the insertion device from the header region; and rinsing and flushing away the removed contaminants from the header region. An apparatus and an insertion device for cleaning a header region of a hemodialyzer are disclosed.Type: GrantFiled: January 12, 2007Date of Patent: January 4, 2011Assignee: Princeton Trade & Technology, Inc.Inventors: Joseph J. Murawski, Yacoob Tabani, Mohamed Eman Labib

Publication number: 20100300486Abstract: A method for removal of wax deposited on an inner wall in contact with a fluid stream. The method includes the steps of cooling the inner wall and the fluid stream to a temperature of or below the wax appearance temperature, enabling wax to dissolve and precipitate on the inner wall, and heating of the inner wall for a short period of time to release the deposited wax from the surface of the inner wall, mainly in the form of solid parts. The thickness of wax deposits in a pipe section can be determined by computing the temperatures obtained upstream and downstream in the said pipe section, before and after applying heat pulse.Type: ApplicationFiled: October 20, 2008Publication date: December 2, 2010Applicant: STATOIL ASAInventors: Ryan Hoffman, Lene Amundsen
