Patent number: 9653961Abstract: A hybrid system includes an electric motor/generator or eMachine with a stator received in a cooling sleeve. The stator is pressed into the cooling sleeve to form a press-fit connection. The press fit connection has sufficient strength to carry the complete torque generated by the eMachine, so the stator will never move relative to the sleeve through the life of the hybrid system.Type: GrantFiled: March 9, 2015Date of Patent: May 16, 2017Assignee: ALLISON TRANSMISSION, INC.Inventor: Jorge E. Silva

Patent number: 9611794Abstract: Various systems and method for controlling exhaust gas recirculation (EGR) in an internal combustion engine are provided. In one embodiment, a method includes during a first operating condition, directing exhaust gas from a first cylinder group into an engine air intake stream and directing substantially no exhaust gas from a second cylinder group to the engine air intake stream. The method further includes during a second operating condition, directing exhaust gas from the second cylinder group through a turbocharger bypass into the engine air intake stream and reducing a fuel injection amount of the first cylinder group relative to a fuel injection amount of the second cylinder group.Type: GrantFiled: July 31, 2012Date of Patent: April 4, 2017Assignee: General Electric CompanyInventors: Neil Xavier Blythe, Shawn Michael Gallagher, James Robert Mischler, Luke Henry

Patent number: 9559366Abstract: In some embodiments, a solid oxide fuel system is provided. The solid oxide fuel cell system may include a chromium-getter material. The chromium-getter material may react with chromium to remove chromium species from chromium vapor. The solid oxide fuel cell system may also include an inert substrate. The chromium-getter material may be coated onto the inert substrate. The coated substrate may remove chromium species from chromium vapor before the chromium species can react with a cathode in the solid oxide fuel cell system.Type: GrantFiled: March 20, 2014Date of Patent: January 31, 2017Assignee: VERSA POWER SYSTEMS LTD.Inventors: Hongpeng He, Anthony Wood

Patent number: 9505991Abstract: There is provided an apparatus (1) and methods for processing biomass to produce charcoal, bio-oil(s) activated carbon, recarburizer carbon, or nut coke by means of microwave energy. The apparatus has a rotatable tube (5) for receiving biomass (108), an electromagnetic generator (7). One method provides applying electromagnetic energy to the biomass (108) and an absorbing material (109). An alternative method provides allowing an indirect, black body radiation field to develop, and exposing the biomass (108) to the black body radiation field and the electromagnetic energy. Another method provides allowing plasma to form and exposing the biomass to the plasma and the electromagnetic energy. Another method provides introducing the biomass to a second container (205), introducing the second container to a first reaction container (5), applying electromagnetic energy to the biomass and an absorbing material (109), allowing a plasma to form in the first container, which heats the biomass in the second container.Type: GrantFiled: November 21, 2012Date of Patent: November 29, 2016Assignee: Carbonscape LimitedInventors: Gregory Thomas Conner, Forrest John Tyrrell-Baxter
