Patent number: 11331166Abstract: Embodiments relate to aligners that are capable of immobilizing a patient's jaw after orthognathic surgery while also applying forces to reposition a patient's teeth. In embodiments, a processor determines, for a treatment stage, a dentition for an upper dental arch and a lower dental arch. The processor applies one or more stabilizing features to the upper dental arch and the lower dental arch. The processor determines whether the one or more stabilizing features will prevent jaw movement while the upper dental arch is engaged with the lower dental arch. Responsive to a determination that the one or more stabilizing features will prevent the jaw movement, the processor stores a first digital model comprising the dentition for the upper arch and the one or more stabilizing features for the upper arch and stores a second digital model comprising the planned dentition for the lower arch and the one or more stabilizing features for the lower arch for each increment of treatment.Type: GrantFiled: July 25, 2018Date of Patent: May 17, 2022Assignee: Align Technology, Inc.Inventors: John Y. Morton, Ken Wu, Juan Carlos Alvarez

Publication number: 20170335275Abstract: A method for leaching secondary and primary sulphides of copper in a ferrous chloride medium with iron-oxidising bacteria adapted from the crushing of the mineral from the mine, includes steps of: mixing the mineral from the crushing with concentrated sulphuric acid; transporting the material mixed with sulphuric acid by means of a belt; adding a liquid leaching solution at an intermediate point during transport on the belt, the solution consisting of: iron (II) sulphate to reduce the redox potential of the solution-mineral mixture to values less than 550 mV Ag/AgCl; iron (III) sulphate; bacteria and archaea of the mesophile- and thermophile-type belonging to the genera Acidithiobacillus, Leptospirillum and Sulfulobos; and sodium chloride to produce a chlorinated environment in solutions. The method also comprises the subsequent steps of: heaping the material on heap pads; during the resting step, injecting air warmed by a liquid/air exchange system; and leaching the heaped material.Type: ApplicationFiled: August 24, 2015Publication date: November 23, 2017Inventor: Juan Carlos Alvarez RodrÃguez

Patent number: 6295816Abstract: An apparatus (11) for controlling the peak pressure in the combustion chamber (46) of a turbo-charged diesel locomotive engine (12). A pressure relief valve (56) is disposed in the compressor discharge downstream of the turbo-charger (18). The relief valve (56) is operable to release a selected amount (58) of the compressed air (24) produced by the compressor section (20) of turbo-charger (18). The actuation of valve (56) may be a function of the pressure of the compressed air (24), and/or a manifold air temperature signal (52) and a fuel injection timing signal (40). An actuator (60) attached to valve (56) is responsive to a valve position signal (62) generated by a controller (38) having the appropriate inputs and programmed logic capability.Type: GrantFiled: May 24, 2000Date of Patent: October 2, 2001Assignee: General Electric CompanyInventors: Shawn Michael Gallagher, Ihab Khalil, Doug Glenn, Juan Carlos Alvarez
