Publication number: 20080053493Abstract: A processing liquid stored in a recovery tank is stored in a purification tank after passing through an impurity removal filter and an ion component removal filter via a pipe by a suction operation of the pump. In the impurity removal filter, impurities (e.g., water, an etching residue, particles, or the like) included in the processing liquid are removed. In the ion component removal filter, an ion component (mainly anions) in the processing liquid including an acid liquid, HFEs, and a hydrophilic organic solvent is removed. In a case where hydrofluoric acid (HF) is used as the acid liquid, fluorine ions (F?) are removed by the ion component removal filter. The ion component removal filter also removes water, a hydrophilic organic solvent, metal ions, or the like included in the processing liquid.Type: ApplicationFiled: September 5, 2007Publication date: March 6, 2008Inventor: Masahiro Kimura

Publication number: 20070186964Abstract: A dishwasher includes a cabinet and a wash system slidably mounted within the cabinet in such a manner that it may be withdrawn horizontally out of the cabinet for loading with dishes. The wash system includes an open top wash chamber having a floor and side walls adapted to accommodate dishes within which wash liquid is sprayed. Two rotating spray arms are mounted in the bottom of the chamber for producing a spray of wash liquid within the chamber. A wash pump for pressurising wash liquid discharges into a manifold located on the floor of the chamber. The spray arms receive wash liquid from the manifold. A drain pump evacuates wash liquid from said chamber. A wash chamber closure is mounted in the top of the cabinet. The closure engages with the wash chamber opening to sealably close off the wash chamber on its retraction into the cabinet.Type: ApplicationFiled: February 12, 2007Publication date: August 16, 2007Inventors: Wayne Andrew Mason, Robert William Todd

Patent number: 7255116Abstract: A system for removing paint and other coatings from hard surfaces is mounted on a truck for over-the-road travel. The truck bed carries a high power vacuum pump, a self propelled tractor with an attached blast head, a liquid reservoir, a sump or vacuum tank, and a ramp for loading the tractor. The reservoir is connected to a low pressure pump that transfers water to the high pressure pump. The high pressure pump is connected to the blast head by a high pressure hose. A vacuum hose is connected to the sump which has an internal enclosure for separating the waste materials from the liquid for easy dumping of semi dried materials.Type: GrantFiled: July 2, 2004Date of Patent: August 14, 2007Inventor: James P. Crocker

Patent number: 7243512Abstract: A filter assembly for a washing machine is provided which uses a simple structure to separate dirt and/or particles from washing water using. The filter assembly includes a filter case with an inlet and an outlet each positioned along its circumference, and an opening within the filler case which allows for communication between the inlet and outlet. A filter is provided in the filter case, the filter having a plate disposed in front of the opening to prevent particles from passing through the opening. Rather, the heavy particles are gathered in a central area of the filter by a centrifugal force generated by the water flowing in the filter case.Type: GrantFiled: November 21, 2003Date of Patent: July 17, 2007Assignee: LG Electronics Inc.Inventors: Keon Kim, Yu Beom Kang, Sang Man Je

Patent number: 7232525Abstract: An automatic tank cleaning system includes a water recycling unit having a weir therein and a conically-shaped bottom, a cutting box having a portable weir therein, a hydrocyclonic separator, and a mud tank. Tank slop is pumped from the mud tank to the water recycling unit where solids collect at the bottom. The solids are removed and collected in the cutting box. Water in the recycling unit may be pumped through the hydrocyclonic separator. Solids removed by the separator are collected in the cutting box and the water is directed into a clean water compartment defined by the weir within the recycling unit. Water in the cutting box is collected by the portable weir therein and pumped to the clean water compartment. Water from the clean water compartment is pumped to one or more rotary jet heads within the mud tank. Overflow from the water recycling unit may be directed to the cutting box. A chemical inductor may be used to add cleaning chemicals to the water prior to being directed through the wash nozzle.Type: GrantFiled: March 18, 2005Date of Patent: June 19, 2007Assignee: M-I L.L.C.Inventor: Frank Eriksen
