Patent number: 11439536Abstract: A contact assembly (301,400) for laser surgery may include a contact lens (402) and an optical filter (404). The contact lens (402) may be configured to be positioned in an optical path of therapeutic radiation (310) directed at an eye (100) of a patient. The optical filter (404) may be coupled to an outer surface (402A) of the contact lens (402). The optical filter (404) may be transparent to the therapeutic radiation (310) with a first wavelength and may be opaque to radiation (318) with a second wavelength different than the first wavelength.Type: GrantFiled: November 22, 2017Date of Patent: September 13, 2022Assignee: LUTRONIC VISION INC.Inventors: Dayan Ban, Rongping Dai, Cameron Graeme Cooke, Heechul Lee

Publication number: 20160288071Abstract: Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. The reactor system may include various system components, such as one or more pre-heaters, heat exchangers and reactor vessels. The system components may be configured to receive a reactor fluid corrosive to an inner surface thereof and to separately receive a protective fluid that has a higher density and is substantially immiscible with the reactor fluid. A rotating element may be configured to generate a rotational force that forces at least a portion of the protective fluid to flow in a layer between the reactor fluid and at least a portion of the inner surface, the layer operating to reduce corrosion by forming a barrier between the reactor fluid and at least a portion of the inner surface.Type: ApplicationFiled: November 12, 2013Publication date: October 6, 2016Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventors: George Charles PEPPOU, Benjamin William MILLAR, Cameron Graeme COOKE

Publication number: 20160075957Abstract: Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. Corrosion protection layers may be configured to provide a physical barrier between component surfaces and subcritical fluid present in one or more subcritical zones during operation of the reactor system. The corrosion protection layers may include glass and silicon carbide, and may be positioned within the one or more subcritical zones to prevent the subcritical fluid from contacting component surfaces susceptible to corrosion from corrosive ions present in the subcritical fluid.Type: ApplicationFiled: May 2, 2013Publication date: March 17, 2016Applicant: EMPIRE TECHNOLOGY DEVELOPMENT LLCInventor: Cameron Graeme COOKE

Patent number: 9132433Abstract: The present invention provides a diverter or flow controller 1.060, 26.060 for controlling a flow on or within an apparatus 1.001, 26.500, including at least one diverter or flow controller element 1.065, 26.2 and one or more displacement members 1.064, 26.064 adapted to move at least part of the diverter or flow controller element 1.065, 26.2 or a corresponding one of the diverter or flow controller element 1.065, 26.2 into or out of contact with a flow path. The invention also provides a remotely controlled diverter or flow controller and is applicable to flow devices or apparatus such as spiral concentrators and banks of these as up-current classifiers, hydraulic classifiers, teeter bed style classifiers, sluices, weirs, or channels.Type: GrantFiled: April 28, 2011Date of Patent: September 15, 2015Assignee: Mineral Technologies Pty LtdInventors: Graeme Cooke, Mark Palmer

Publication number: 20140048159Abstract: The present invention provides a distributor for distribution of a liquid to a mineral processing apparatus, the distributor including a housing formed by an outer wall and a central chamber formed by an inner wall and located in the housing, the central chamber being adapted to receive the liquid for distribution to distribution chambers located between the outside of the central chamber and an internal surface of the housing, characterised in that passage from the central chamber to respective ones of the distribution chambers is by means of respective apertures which are formed through a generally horizontally oriented surface formed as part of the inner wall.Type: ApplicationFiled: April 30, 2012Publication date: February 20, 2014Applicant: MINERAL TECHNOLOGIES PTY LTDInventors: Graeme Cooke, Tom Lawson, Mark Palmer, Andrew Foster

Patent number: 8459465Abstract: A spiral concentrator has a spiral trough (2.001) has a concentrate gutter (2.010) and a pocket (2.008) located near the outer edge of the gutter. An inflatable bladder (2.012) is located in the pocket and can be deformed from a first state in which the bladder does not interfere with the flow of the slurry, to a second state, in which the bladder diverts the concentrate towards a concentrate gutter (2.101). Alternatively, a spiral trough has a deformable device that sits above and separate from the trough and acts as a flow diverter. As the device changes form, shape or state, it gradually contacts the trough or flow diverting more or less concentrate in a controlled manner.Type: GrantFiled: July 30, 2009Date of Patent: June 11, 2013Assignee: CPG Resources-Mineral Technologies Pty LtdInventor: Graeme Cooke
