Patent number: 5261967Abstract: A method of removing rosin soldering flux or other residues from a printed wiring board comprises directly adding to the wash water which contacts the boards a powdered cleaning composition which comprises water soluble alkaline salts. The method of directly adding the cleaning composition to the water supply in the form of a powder eliminates the need to incorporate organic stabilizers which previously have been required to maintain surfactants and the like in solution in aqueous concentrates. By reducing the organic content of the cleaning compositions, the aqueous effluents from the cleaning method have substantially reduced biological oxygen demand (BOD) and chemical oxygen demand (COD) levels.Type: GrantFiled: June 10, 1992Date of Patent: November 16, 1993Assignee: Church & Dwight Co, Inc.Inventors: Anthony E. Winston, Keith A. Jones, Francis R. Cala, Alfredo Vinci, M. Stephen Lajoie

Patent number: 5225225Abstract: The present invention provides an improved leavening system which comprises at least one leavening acid and at least one novel chemical leavening base. The new chemical leavening bases comprise a baking bicarbonate, preferably an alkali metal bicarbonate, ammonium bicarbonate, or a mixture thereof, which has been intimately admixed with a food grade, essentially water insoluble salt or oxide, such that the baking carbonate acts as a carrier for the insoluble salt or oxide which is essentially uniformly distributed throughout and in the surface of the bicarbonate. The leavening system can be used in any type of baked goods which is leavened by a leavening system which includes a gas generating base such as a baking carbonate and a neutralizing acid.Type: GrantFiled: September 30, 1992Date of Patent: July 6, 1993Assignee: Church & Dwight Co., IncInventors: Mary E. C. Thomas, M. Stephen Lajoie
