Patent number: 8241388Abstract: 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: October 28, 2009Date of Patent: August 14, 2012Assignee: EcoPlus, Inc.Inventor: Ralph W. Rogers

Patent number: 3984259Abstract: An improved cartridge case is fabricated from rod or bar stock formed from a billet of an alloy containing, by weight, 5.2 to 6.2% Zn, 1.9 to 2.5% Mg, 1.2 to 1.9% Cu, 0.18 to 0.25% Cr, the remainder essentially aluminum. The method of fabrication of the cartridge case from a billet of the alloy comprises a controlled sequence of steps in forming rod or bar working stock so as to ensure against the formation of coarse recrystallized grains and the consequent forming of surface cracks or checks in subsequent metal working operations which include segmenting the rod, annealing the segmented parts and thereafter forming such segments into cartridge cases by cupping and wall ironing procedures. The mouth of the case can be annealed for ease of forming a retaining groove about a projectile positioned in the mouth of the case and in some instances for providing resistance to stress corrosion cracking.Type: GrantFiled: August 22, 1975Date of Patent: October 5, 1976Assignee: Aluminum Company of AmericaInventors: Ralph W. Rogers, Jr., Charles H. Deveney, Edsel W. Johnson

Patent number: 3945861Abstract: An improved automotive bumper or bumper back-up bar is provided in an aluminum alloy containing selected amounts of zinc and magnesium with a small amount of zirconium and copper, with small amounts of chromium and manganese being optional but preferred. Copper is included to enhance strength. The alloy can contain 5.5-9% Zn, 0.8-2% Mg, 0.11-0.25% Cu, 0.05-0.2% Zr, and preferably 0.05-0.35% Mn or 0.05-0.25% Cr, or both. The alloy products contemplated include shaped sheet and extrusion bumper products. The improved method contemplates homogenization at a controlled temperature and control of subsequent thermal exposure to, in cooperation with the homogenization, assure good performance from the standpoint of both strength and resistance to stress corrosion cracking.Type: GrantFiled: April 21, 1975Date of Patent: March 23, 1976Assignee: Aluminum Company of AmericaInventors: William A.
