Patent number: 11827336Abstract: A system for controlling a propeller having a plurality of blades having a primary control system and a backup control system. The primary control system including a sensor responsive to a propeller state, and a controller connected to the sensor and to an electrohydraulic control actuator. The electrohydraulic control actuator is connected via a bypass valve to a hydraulic actuator that controls at least a blade angle of a blade of the propeller. The controller generating commands to the electrohydraulic control actuator based on at least the propeller state. The backup control system including a second controller, an electrohydraulic solenoid operably connected to the bypass valve. The backup control system is operable to hydraulically disable the primary control system via the bypass valve upon the occurrence of a selected condition, the second controller modulates the operation of the electrohydraulic solenoid to control the bypass actuator based on the propeller state.Type: GrantFiled: December 17, 2019Date of Patent: November 28, 2023Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Timothy Maver, Julien Lassalle, Thibaut Marger, Gregory Giddings, Charles L. DeGeorge, Stephen J. Bukowinski, Romain Bouloc

Patent number: 10125859Abstract: A gearbox system includes a gearbox having integrated therein a pump system, a plurality of fluid passages and a clutch control system. The pump system is in fluid communication with the clutch control system via the fluid passages to flow at least one pressurized stream. A first pressurized stream controls a first pressure-responsive device included in the clutch control system. The gearbox system further includes a hydro-mechanical control unit (HMCU) in fluid communication with the gearbox to receive a second pressurized stream and to generate at least one actuator control stream. The actuator control stream controls an actuator integrated in the gearbox.Type: GrantFiled: November 25, 2015Date of Patent: November 13, 2018Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Timothy P. Walgren, Dean A. Norem, Charles L. DeGeorge, Alex Rak, Raymond N. Weyl, Ricky D. Reimers

Patent number: 6159256Abstract: A fuel processing system is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, naphtha, light hydrocarbon fuels such as butane, propane, natural gas, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds react with the nickel reactant, and are converted to nickel sulfide while the desulfurized organic remnants continue through the remainder of the fuel processing system. The system does not require the addition of steam or a hydrogen source to the fuel stream prior to the desulfurizing step.Type: GrantFiled: November 12, 1999Date of Patent: December 12, 2000Assignee: International Fuel Cells, LLCInventors: Leonard J. Bonville, Jr., Charles L. DeGeorge, Peter F. Foley, Jay Garow, Roger R. Lesieur, John L. Preston, Jr., Donald F. Szydlowski
