Patent number: 7828903Abstract: A method for removing pipe tuberculation includes the initial step of preparing an access point in the existing pipe by digging to the pipe and sawing a section from the pipe or creating an access port. The section of the pipeline to have its tuberculation removed is isolated by closing valves or creating another access point and sealing the end. Then, a reaming tool is introduced to the interior of the pipe. The reaming tool is attached to a hollow rod string capable of producing moderate thrust and pullback force, and must also produce sufficient torque when rotated. A horizontal directional drilling or “HDD” machine on the surface or in a pit dug out for this purpose applies the aforementioned forces to the rod string.Type: GrantFiled: May 18, 2007Date of Patent: November 9, 2010Assignee: Earth Tool Company LLCInventor: Steven W.

Patent number: 7799144Abstract: A method of cleaning a filter component comprises subjecting the component to an atmosphere of superheated steam at a pressure of a least 0.5 bar in a vessel and subsequently decompressing the vessel to achieve a pressure reduction of at least 0.5 bar in at most 5 seconds. The method is particularly useful for the cleaning of filter components that have been used for the filtration of molten polymer (e.g. polyester) and which are at least partially blocked by solidified polymer.Type: GrantFiled: May 28, 2004Date of Patent: September 21, 2010Assignee: Longworth Engineering Ltd.Inventors: Peter John Norris, John Norris, Christopher Reid, James Peter Millington

Patent number: 7793676Abstract: The invention relates to a method for supplying a paint application device with paint, whereby a determined amount of paint is transported between two scrapers through a scraper line, from a first scraper station which can be connected to a paint supply source, to a second scraper station which can be connected to the paint application device. Said scraper line is cleaned on the return path from the second scraper station to the first scraper station, by a cleaning product which is also transported between the two scrapers. In this way, the scraper line can be cleaned in a reliable manner, with a simple embodiment of the scraper, thus rendering the inventive method especially useful when a color change is carried out.Type: GrantFiled: June 18, 2003Date of Patent: September 14, 2010Assignee: Eisenmann Lacktechnik GmbH & Co.

Patent number: 7789970Abstract: Means for obtaining accurate knowledge of location and amount of fouling inside a heat exchange system, such as a boiler of a power plant, are provided. According to the invention this knowledge can be used to optimize cleaning of a heat exchange system. The system of the invention comprises: Means for measuring particles in the exhaust gas stream of the heat exchange system. These particles are at least partly released when cleaning a certain part of the heat exchange surface of the heat exchange system. Means for creating information of the fouling in an electronic memory by linking together coordinates of the part of the heat exchange surface being cleaned and the measurement data created during the cleaning of said part.Type: GrantFiled: March 31, 2004Date of Patent: September 7, 2010Assignee: Foster Wheeler North America Corp.Inventor: Tomas Rosin
