The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. This cleaning and disinfecting method works in a variety of industrial water systems including cooling water systems.Type: GrantFiled: April 30, 2002Date of Patent: March 11, 2014Assignee: Nalco CompanyInventors: Andrew J. Cooper, Jasbir S. Gill, Amit Gupta, Robert F. Kelly, Douglas G. Kelley, Eric R. Myers

Patent number: 8657964Abstract: A method for dispensing a liquid or pasty cleaning agent and a liquid or pasty bleaching agent into a wash tub of a household dishwasher that includes a housing and a dispensing system disposed in the housing. The dispensing system separately stores and discharges the cleaning agent and bleaching agent. The method includes providing the dispensing system with respective reservoirs for each of the cleaning agent and the bleaching agent that have different capacities from each other. Each of the capacities are larger than needed for a single wash cycle. A first quantity of the cleaning agent and a second quantity of the bleaching agent are dispensed during a wash cycle, and the ratio of the dispensed quantities corresponds to the ratio of the capacities of the respective reservoirs.Type: GrantFiled: November 14, 2006Date of Patent: February 25, 2014Assignee: Miele & Cie. KGInventors: Markus Druecker, Joerg Kinnius, Monika Seifert, Dirk Wegener, Cornelius Wolf

Patent number: 8652267Abstract: There is disclosed a coated-type silicon-containing film stripping process for stripping off to remove a coated-type silicon-containing film obtained by coating a silicon-containing film composition used in a lithography on a substrate, comprising, at least: a first step of treating the silicon-containing film with an acidic stripping solution containing sulphate ion and/or fluoride ion; and a second step of treating the silicon-containing film with an alkaline stripping solution containing a nitrogen compound. There can be provided a process for allowing a silicon-containing film, which has not been conventionally removed unless dry stripping is adopted, to be removed by a stripping process based on a stripping solution (wet stripping).Type: GrantFiled: November 9, 2009Date of Patent: February 18, 2014Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Tsutomu Ogihara, Takafumi Ueda, Toshiharu Yano, Shozo Shirai

Patent number: 8647443Abstract: A method of cleaning an automatic biochemical analyzer, wherein the cleaning solution includes: at least one anionic surfactant, at least one nonionic surfactant, an alkali metal hydroxide, an alkali metal citrate, and a buffering agent stabilizing the pH value above 13.0. In some embodiments, the cleaning solution provides low residual rate of proteins, low residual rate of lipids, desirable within-batch repeatability in clinical testing, low level of cross-contamination, and low level of reactant deposit after cleaning, without affecting test results of the biochemical analyzer. In some embodiments, the cleaning solution has no corrosive effects on the liquid path and reaction cup of the analyzer. The ingredients of the cleaning solution may also be biodegradable.Type: GrantFiled: May 20, 2011Date of Patent: February 11, 2014Assignee: Shenzhen Mindray Bio-Medical Electronics Co., Ltd.Inventors: Yuping Zhang, Mulong Liu, Wenjuan Xu, Jun Cheng

Patent number: 8591662Abstract: A method for cleaning a substrate is provided. The method initiates with applying an activation solution to a surface of the substrate. The activation solution and the surface of the substrate are contacted with a surface of a solid cleaning surface. The activation solution is absorbed into a portion of the solid cleaning element and then the substrate or the solid cleaning surface is moved relative to each other to clean the surface of the substrate. A method for cleaning the surface of the substrate with a solid cleaning element that experiences plastic deformation is also provided. Corresponding cleaning apparatuses are also provided.Type: GrantFiled: October 26, 2012Date of Patent: November 26, 2013Assignee: Lam Research CorporationInventors: Erik M. Freer, John deLarios, Katrina Mikhaylichenko, Michael Ravkin, Mikhail Korolik, Fred C. Redeker

Patent number: 8557049Abstract: The present invention relates to a method for the purification of substrates, characterized in that the purification is carried out by at least one oxidation agent, selected from the group consisting of permanganate and ferrate (VI), and subsequently by a reduction agent. Organic residue, such as legionella or extracellular polymer substances (EPS) can be removed from surfaces of filtration or classification devices and from transport and storage devices utilizing said method. The use of oxidation agents further relates to the oxidation of extracellular polymer substances (EPS).Type: GrantFiled: August 27, 2008Date of Patent: October 15, 2013Inventor: Rainer Fulling
