Patent number: 7736606Abstract: A process for leaching a value metal from a base metal sulfide ore, comprising the step of leaching the ore with a lixiviant comprising a chloride, an oxidant and hydrochloric acid is disclosed. The leaching is controlled, by use of low concentrations of hydrochloric acid and a redox potential, to effect formation of hydrogen sulfide from the base metal sulfide ore. The hydrogen sulfide is stripped from the leach solution, thereby reducing the amount of sulfate generated in the leach to very low levels. The leaching may also be conducted to limit the co-dissolution of platinum group metals and gold with the base value metals. The leach forms a value metal-rich leachate and a solids residue. The solids residue may be subsequently leached to recover the platinum group metals and gold. The value metal-rich leachate can be is oxidized and neutralized to recover the value base metals. In an embodiment, the chloride is magnesium chloride and lixiviant solution is regenerated.Type: GrantFiled: September 28, 2004Date of Patent: June 15, 2010Assignee: Jaguar Nickel Inc.Inventors: G. Bryn Harris, Vaikuntam I. Lakshmanan, Ramamritham Sridhar, George Puvvada

Patent number: 7704534Abstract: Oil seed protein isolates, particularly canola protein isolate, are produced continuously from oil seed meals, preferably at a high purity level of at least about 100 wt % (Nx 6.25), by a process wherein oil seed protein is continuously extracted from oil seed meal, the resulting protein solution is continuously concentrated, preferably to a protein content of at least about 200 g/L, and the concentrated protein solution is continuously mixed with chilled water having a temperature below about 15° C. to form protein micellar, which are settled in the settling vessel to provide a protein micellar mass (PMM) while supernatant overflows the vessel. The PMM, when accumulated to a desired degree, may be separated from supernatant and dried. The supernatant may be processed to recover additional oil seed protein isolate.Type: GrantFiled: August 26, 2008Date of Patent: April 27, 2010Assignee: Burcon NutraScience (MB) Corp.Inventors: Larry D.

Patent number: 7484508Abstract: Method and apparatus for non-invasively determining the time onset (Tonset) and end (Tend) of patient inspiratory efforts. A composite pressure signal is generated comprising the sum of an airway pressure signal, a gas flow pressure signal obtained by applying a gain factor (Kf) to a signal representing gas flow rate and a gas volume pressure signal obtained by applying a gain factor (Kv) to a signal representing volume of gas flow. Kf and Kv values are adjusted to result in a desired linear trajectory of composite pressure signal baseline in the latter part of the exhalation phase. The current composite pressure signal is compared with (i) selected earlier composite pressure signal values and/or (ii) value expected at current time based on extrapolation of composite pressure signal trajectory at specified earlier times and/or (iii) the current rate of change in the composite pressure signal with a selected earlier rates of change.Type: GrantFiled: June 27, 2003Date of Patent: February 3, 2009Assignee: YRT LimitedInventor: Magdy Younes
