Patent number: 8088354Abstract: Process for the preparation of quasi-crystalline boehmite comprising the steps of: (a) preparing an aqueous precursor mixture comprising a water-insoluble aluminum source; (b) decreasing the pH of the precursor mixture of step (a) by at least 2 units; (c) increasing the pH of the mixture of step (b) by at least 2 units, and (d) aging the mixture of step (c) under hydrothermal conditions to form a quasi-crystalline boehmite. This process provides for the hydrothermal preparation of quasi-crystalline boehmites with high peptizability. The invention therefore further relates to quasi-crystalline boehmites with a high peptizability, measured as the Z-average submicron particle size. This Z-average submicron particle size preferably is less than 500 nm, more preferably less than 300 nm, even more preferably less than 200 nm, and most preferably less than 100 nm.Type: GrantFiled: November 19, 2004Date of Patent: January 3, 2012Assignee: Albemarle Netherlands B.V.Inventors: Erik Jeroen Laheij, Paul O'Connor, Dennis Stamires, Edisson Morgado, Jr., Marco Antonio Santos de Abreu, Márcio Fernandes, Michael Brady

Patent number: 7975896Abstract: Friction plug welding methods and systems plug a hole extending through a component part from front and back faces thereof. A sacrificial plate having an opening therethrough may be positioned against the back face of the component part with assistance from a restraint part (which is also preferably provided with a space of sufficient dept to receive a terminal end of the male plug) so that the opening is coaxially aligned with the hole to be plugged. Upon advancing a male plug of a plug rod into the hole under friction plug welding conditions, a friction weld region will therefore be formed between the male plug and defining surfaces of both the hole extending through the component part and the opening extending through the sacrificial plate. The plug rod may include an annular shoulder flange which defines a plane parallel to the front face of the component part so that flash flow from the friction welding will be displaced laterally of the hole. The male plug may be frustroconically shaped.Type: GrantFiled: December 9, 2009Date of Patent: July 12, 2011Assignee: Embraer—Empresa Brasileira de Aeronautica S.A.Inventor: Marcio Fernandes Maciel

Publication number: 20050039167Abstract: A compiling method compiles an object program to be executed by a processor having a plurality of execution units operable in parallel. In the method a first availability chain is created from a producer instruction (p1), scheduled for execution by a first one of the execution units (20: AGU), to a first consumer instruction (c1), scheduled for execution by a second one of the execution units (22: EXU) and requiring a value produced by the said producer instruction. The first availability chain comprises at least one move instruction (mv1-mv3) for moving the required value from a first point (20: ARF) accessible by the first execution unit to a second point (22: DRF) accessible by the second execution unit.Type: ApplicationFiled: October 7, 2002Publication date: February 17, 2005Inventors: Marcio Fernandes, Raymond Livesley
