Patent number: 7225757Abstract: A method of cleaning bedding sand soiled with animal manure removes the bedding sand from an animal bedding area. An aqueous slurry of the bedding sand is made. The slurry is subjected to cyclonic action so as to separate the sand from the manure. The separated sand is then respread back into the animal bedding area for reuse. The clean bedding sand is free of organic contaminants such as manure, urine and milk. In addition, the bedding sand may contain inorganic contaminants such as clay and silt particles as well as fine particles which are undesirable in a bedding material. Processing the sand removes these inorganic contaminants and fine particles to produce a superior bedding sand for animals.Type: GrantFiled: March 8, 2005Date of Patent: June 5, 2007Inventor: Paul J. Fagan

Patent number: 6613923Abstract: The present invention is a process for the catalytic hydrogenation of ketones and aldehydes to alcohols at low temperatures and pressures using organometallic molybdenum and tungsten complexes and the catalyst used in the process. The reactants include a functional group which is selected from groups represented by the formulas R*(C═O)R′ and R*(C═O)H, wherein R* and R′ are selected from hydrogen or any alkyl or aryl group. The process includes reacting the organic compound in the presence of hydrogen and a catalyst to form a reaction mixture. The catalyst is prepared by reacting Ph3C+A− with a metal hydride. A− represents an anion and can be BF4−, PF6−, CF3SO3− or Bar′4−, wherein Ar′=3,5-bis(trifluoromethyl)phenyl.Type: GrantFiled: April 19, 2000Date of Patent: September 2, 2003Assignee: Brookhaven Science Associates, LLCInventors: R.
