Patent number: 6076229Abstract: An aqueous surface cleaning composition consists essentially of water and a surfactant. The surfactant is incorporated, preferably, at a concentration of 10-100 parts per million, by weight as a proportion of the entire composition, and more preferably is within the range of about 70-93 ppm. The preferred surfactant is sodium octyl sulfate, which is resistant to combining or interacting with ozone and has the desired foaming characteristics. Other ozone resistant surfactants may be employed, alone or in combination with one another. The liquid cleaning composition is used advantageously in a fluid cycling cleaning system or a recycling system in which the liquid is provided from a canister to a cleaning tool head, then returned over a vacuum conduit to the canister for filtration and reuse.Type: GrantFiled: November 25, 1997Date of Patent: June 20, 2000Assignee: CFR CorporationInventor: Edward D.

Patent number: 6066611Abstract: The invention herein provides bleaching compositions comprising a protease enzyme which is a carbonyl hydrolase variant having an amino acid sequence not found in nature, which is derived by replacement of a plurality of amino acid residues of a precursor carbonyl hydrolase with different amino acids, wherein said plurality of amino acid residues replaced in the precursor enzyme correspond to position +76 in combination with one or more of the following residues: +99, +101, +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274, where the numbered positions corresponds to naturally-occurring subtilisin from Bacillus amyloliquefaciens or to equivalent amino acid residues in other carbonyl hydrolases or subtilisins (such as Bacillus lentus subtilisin) and a bleaching agent.Type: GrantFiled: May 1, 1997Date of Patent: May 23, 2000Assignee: The Procter & Gamble CompanyInventors: Chanchal Kumar Ghosh, Michael Eugene Burns, David Neil DiGiulio, Edward Eugene Getty, Richard Timothy Hartshorn, Alan David Willey, Philip F.
