Patent number: 9394109Abstract: A spiral conveyor for positively driving a hinged, modular conveyor belt along a helical path. The spiral conveyor includes a rotating cylindrical tower with parallel drive members extending from the bottom to the top of the tower on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the tower for engaging the inside edges of the belt. In one version, the ridges at the entrance end of the spiral are movable to provide a gradually decreasing spacing between consecutive ridges as the belt enters the spiral. In another version, alignment elements at the entrance end align belt-edge structure with the tip ends of associated ridges to help engagement. In another version, the ridges at a discharge end of the tower are retractable between an extended position driving the belt and a retracted position.Type: GrantFiled: March 12, 2013Date of Patent: July 19, 2016Assignee: Laitram, L.L.C.Inventors: Casper Fedde Talsma, David W. Bogle, Achraf Elhassouni, David A. Wickham

Patent number: 8721643Abstract: An instrumented orthopaedic implant, such as an intramedullary (IM) nail, is disclosed. The implant has the capacity to provide an accurate measurement of the applied mechanical load across the implant. The implant includes sensors and associated electronic components located in recesses on the outer surface of the implant. The implant houses the sensing apparatus, the interface circuitry, the data transmitter, and the power receiver. The hermetically sealed housing is adapted for implantation in the body of a patient. The implant is used with a controller which communicates with it by telemetry, and there is an acting unit connected to the electronic components which is adapted to carry out a function based upon a condition detected by the sensors.Type: GrantFiled: July 16, 2012Date of Patent: May 13, 2014Assignee: Smith & Nephew, Inc.Inventors: Robert L. Morgan, Mark David Wickham, Peter A. Brady, Sied W. Janna, Gene Edward Austin, Darren James Wilson

Patent number: 7442669Abstract: The present invention provides metal-exchanged hexaaluminate catalysts that exhibit good catalytic activity and/or stability at high temperatures for extended periods with retention of activity as combustion catalysts, and more generally as oxidation catalysts, that make them eminently suitable for use in methane combustion, particularly for use in natural gas fired gas turbines. The hexaaluminate catalysts of this invention are of particular interest for methane combustion processes for minimization of the generation of undesired levels (less than about 10 ppm) of NOx species. Metal exchanged hexaaluminate oxidation catalysts are also useful for oxidation of volatile organic compounds (VOC), particularly hydrocarbons. Metal exchanged hexaaluminate oxidation catalysts are further useful for partial oxidation, particularly at high temperatures, of reduced species, particularly hydrocarbons (alkanes and alkenes).Type: GrantFiled: March 5, 2003Date of Patent: October 28, 2008Assignee: TDA Research, Inc.Inventors: David Wickham, Ronald Cook
