Patent number: 8956665Abstract: Stable aqueous compositions of silane quaternary ammonium compounds are provided by diluting an alkanol solution of the silane quaternary ammonium compound in water with at least one nonionic surfactant. The weight ratio of the silane quaternary ammonium compound and nonionic surfactant is provided to yield a composition which can remain stable in dilute aqueous compositions, can be applied to any surface and dry quickly to provide an anti-microbial film. The addition of an alkali metal bicarbonate salt to the composition improves the anti-microbial properties as well as the drying time of the composition.Type: GrantFiled: December 13, 2007Date of Patent: February 17, 2015Assignee: Church & Dwight Co., Inc.Inventors: Steven A.

Patent number: 8679803Abstract: The present invention is directed to the enhanced production of ethanol from fermentation using an ethanol producing microorganism. In particular, the present invention provides a process for the enhanced growth and metabolism of an ethanol producing microorganism (e.g., yeast), for the purpose of increasing or enhancing ethanol production, both in terms of total ethanol produced and in terms of the time required for ethanol producing microorganisms to convert carbohydrates and/or sugars to end products (i.e., ethanol). In accordance with this invention bicarbonate ions are used to enhance ethanol fermentation and/or reduce the time required for ethanol producing microorganisms to convert carbohydrates and/or sugars to end products, i.e., ethanol. The present invention can also be used for enhancing fermentation end products in, for example, the fuel ethanol, industrial, cheese, brewing, and wine making industries.Type: GrantFiled: April 28, 2011Date of Patent: March 25, 2014Assignee: Church & Dwight Co., Inc.Inventors: Melvin H. Czechowski, Steven A. Bolkan

Patent number: 8182851Abstract: This invention provides a control release formulation or rumen-bypass dietary supplement in compacted form. The formulation or supplement has the capability to transport fatty acid calcium salt and between about 1-75 percent of one or more rumen-protected undegraded biologically active agents to the post-ruminal digestive system of a ruminant. A feedstock containing the formulation or supplement for ruminants beneficially improves feed efficiency and body growth. The feedstock also is adapted to improve the lactational performance of dairy cattle.Type: GrantFiled: April 9, 2009Date of Patent: May 22, 2012Assignee: Church & Dwight Co., Inc.Inventors: Edward A.

Patent number: 7615109Abstract: A vacuum cleaner bag filter with one or more filter walls forming a generally air permeable enclosure having a bag opening through it, and a flange attached to the one or more filter walls to cover the bag opening. The filter walls have a working surface area through which air can pass during use, and the flange is a relatively rigid structure having an air inlet passing into the air permeable enclosure. One or more deodorizing sheets are attached to an inner surface of the one or more filter walls. The deodorizing sheets include a first sheet layer, and sodium bicarbonate particles operatively associated with the first sheet layer. The deodorizing sheets may cover less than about 30% of the working surface area, a single deodorizing sheet may be provided, and the deodorizing sheets may be attached to the filter walls by an air impermeable adhesive that covers at least about 5% of the surface area of the deodorizing sheets.Type: GrantFiled: May 4, 2006Date of Patent: November 10, 2009Assignee: Electrolux Home Care Products, Inc.Inventors: Arnold Sepke, Steven A.

Patent number: 5863877Abstract: A non-bleaching cleaning composition, e.g. laundry detergent, wherein the solids content comprises at least about 70 wt. % of sodium carbonate, and up to about 12 wt. % of elemental magnesium in the form of a water soluble salt, e.g., magnesium sulfate or magnesium chloride, based on the total weight of the solids composition. Preferably the composition also contains an active surfactant and, when used as a laundry detergent, a polymeric polycarboxylate, e.g., an acrylic acid polymer. Incorporation of magnesium ions in the foregoing cleaning composition containing carbonate ions is intended to minimize negative interactions that will occur between the precipitation of calcium carbonate and the substrate being cleaned, e.g., fabric encrustation when the composition is used as a laundry detergent.Type: GrantFiled: May 17, 1996Date of Patent: January 26, 1999Assignee: Church & Dwight Co., Inc.Inventors: Charles D.
