Patent number: 7384562Abstract: The invention is a process for treatment of brown grease, where the brown grease comprises water, food solids and free-oil. This process starts with the collection of the brown grease into a container. The brown grease's pH is adjusted with a chemical treatment to produce an adjusted brown grease phase. To the adjusted brown grease phase an anionic copolymer treatment mixture is added along with a cationic copolymer to form a reaction mixture. The reaction mixture reacts for a period of time, and during this time wastewater is discharged from the reaction mixture to produce resulting solids. The resulting solids are then transferred from the container for disposal or are processed further into a fuel or soil additive.Type: GrantFiled: August 2, 2005Date of Patent: June 10, 2008Assignee: EcoPlus, Inc.Inventor: Ralph W. Rogers

Patent number: 7365219Abstract: The invention relates to a novel extraction method for obtaining at least one unsaturated, optionally derivatized compound, from mixtures of said compounds with other less saturated constituents, e.g. for obtaining polyunsaturated fatty acids or the derivatives thereof from mixtures with saturated and/or less unsaturated, optionally derivatized fatty acids, by means of selective complexation with a cation exchanger which is partially or fully charged with silver ions, and subsequent decomplexation.Type: GrantFiled: June 5, 2002Date of Patent: April 29, 2008Assignee: Nutrinova Nutrition Specialties & Food Indredients GmbHInventors: Dirk Fabritius, Silke Reimann, Doreen Neumann, Daniel Minoer

Patent number: 7351088Abstract: An electrical connector, a ring-like locking sheet with inner and outer teeth of which is fixed at the end of its plug connector; and a circumferential bulge, with trapezoid cross section which has an upslope, a flat top and a down-slope, is provided on the surface of the outer conductor of the socket connector. Therefore, in the process of connection, the inner teeth reach the max flexural deformation when go up along the slope to the flat top. When reach the down-slope, the deformed inner teeth gradually restore the original state in tangential direction of the down-slope, and finally stop at the down-slope or at the juncture of the down-slope and the flat top. The electrical connector according to the present invention can have a rigid zero clearance between the interfaces in connection, and at the same time can keep a very strong axial force.Type: GrantFiled: June 14, 2007Date of Patent: April 1, 2008Inventor: Jinliang Qu

Patent number: 7243600Abstract: An ink pan for a rotogravure printing press has a reservoir and a dam. The dam is located within the reservoir and divides the reservoir into an intake section and an outtake section. A gate is within the dam. The gate has an open position and a closed position. When the gate is closed the dam maintains an ink in the intake section until the ink exceeds a depth greater than the height of the dam, and then the ink flows over the dam into the outtake section. When the gate is in an open position the gate allows ink in the intake section to be emptied into the outtake section.Type: GrantFiled: May 3, 2006Date of Patent: July 17, 2007Assignee: Flxon IncorporatedInventor: Steven E. Boettcher
