Patent number: 6162302Abstract: A cleaning method for a quartz substrate includes mixing a rinsing solution and mixing a cleaning solution such that the solutions are electrically conductive. The rinsing solution is carbonated and is used in more than one step within the method. The cleaning solution includes ammonium hydroxide. As a result of the electrical conductivity of the solutions, the cleaning method is less susceptible to surface damage caused by electrostatic discharge. The sequence of steps includes rinsing the quartz substrate with the carbonated rinsing solution, removing loose contaminants by a high pressure application of the cleaning solution, and removing organic contaminants in a strong oxidation environment using a solution of sulfuric acid and hydrogen peroxide. The carbonated rinsing solution is again applied, followed by another high pressure application of the cleaning solution and a final rinse with the carbonated rinsing solution.Type: GrantFiled: November 16, 1999Date of Patent: December 19, 2000Assignee: Agilent TechnologiesInventors: Nadipuram V.

C., and mixtures of such solvents;(b) an effective amount of at least one semi-polar nonionic surfactant, said surfactant having the structure: ##STR1## wherein R.sup.1 is C.sub.5-20 alkyl, R.sup.2 and R.sup.3 are both C.sub.1-4 alkyl, or --(CH.sub.2).sub.p --OH, although R.sup.2 and R.sup.3 do not have to be equal, and p is 1-6;(c) an effective amount of a buffering system which comprises a nitrogenous buffer which will result in a pH of greater than 6.5; and(d) the remainder as substantially all water.Type: GrantFiled: June 3, 1996Date of Patent: October 6, 1998Assignee: The Clorox CompanyInventors: Aram Garabedian, Jr., Scott C. Mills, William P. Sibert, Clement K. Choy

Patent number: 5804541Abstract: A floor stripper composition is provided, having a pH-value above 9.0, and comprising a soap, water and a glycine-N,N-diacetic acid compound, which is preferably methylglycine diacetic acid (MGDA). The diacetic acid is desirably in the form of a divalent metal complex thereof. A process is also provided for removing a zinc containing acrylate polymer film from a floor surface, wherein a floor stripper composition of the invention is applied. A good floor stripper performance could be obtained with this composition owing to its low foaming behaviour.Type: GrantFiled: June 19, 1997Date of Patent: September 8, 1998Assignee: Diversey Lever, Inc.Inventor: Josef Jans

Patent number: 5782989Abstract: Polymer scale removal from vinyl polymerization reactors is effected without the use of polar aprotic solvents or aromatic solvents, by adding to the reactor, a scale removal composition comprising acetone, a most minor amount of a strong base, and a minor amount of a hydroxyl- or amino-functional polar organic solvent. The composition may contain surfactants, chelating or sequestering agents, detergent builders, and the like, and water in amounts of up to about 3 weight percent. Scale removal is efficient and rapid when the scale removing composition is agitated in the reactor at temperatures ranging from about 50.degree. C. to 120.degree. C.Type: GrantFiled: November 19, 1997Date of Patent: July 21, 1998Assignee: Arco Chemical Technology, L.P.Inventor: Michael A. Rueter
