Patent number: 10005180Abstract: Herein is disclosed a multifunctional tool with replaceable tool tips. The disclosed multifunctional tool may be used as an end-effector on a robotic arm in space. Each tool tip, when in the tool holder, is driven by a common motor. The same motor can also be used to control the orientation of the tool tip about an axis. The tool tips are replaceable in the tool holder by simple and robust means, resulting in a lighter and cheaper multifunctional tool. The tool tips can be variously adapted to perform a variety of functions, including cutting, grasping, drilling, driving, etc. Since the tool may be driven by only one actuator, and the single actuator may be used to drive both the tool and rotation of the tool, mass can be saved. Use of such a multifunctional tool also reduces overall system power requirements, and system complexity.Type: GrantFiled: June 12, 2017Date of Patent: June 26, 2018Assignee: MACDONALD, DETTWILER AND ASSOCIATES INC.Inventors: Paul Roberts, Stephen Bratsberg, Giuseppe Rago

Patent number: 8292597Abstract: A gear pump comprises a casing having an inlet, an interior, and an outlet. An inlet gear is positioned at the inlet and pressurizes fluid received at the inlet. A drive gear is positioned at the outlet of the casing, the drive gear receiving fluid pressurized by the inlet gear to output pressurized fluid at the outlet. A speed-reduction gear is meshed to the drive gear and connected to the at least one inlet gear, the speed-reduction gear having a greater number of teeth than the drive gear to reduce a rotational speed from the drive gear to the inlet gear, such that the inlet gear has a lower speed that the drive gear. An input shaft is coupled to the drive gear and receives a rotational input to actuate the drive gear.Type: GrantFiled: October 16, 2008Date of Patent: October 23, 2012Assignee: Pratt & Whitney Canada Corp.Inventor: Giuseppe Rago

Patent number: 7043898Abstract: A gas turbine engine including a gas exhaust duct assembly which comprises an annular shroud forming at least a section of an inner wall of a gas exhaust duct, a plurality of strut members radially projecting from the shroud, and a plurality of insert members. The strut members are disposed in a circumferentially, substantially equally spaced-apart relationship, and extend in a substantially axial direction. The insert members each define a circumferential section of an outer wall of the gas exhaust duct and are positioned in a space between adjacent strut members, and are secured to same.Type: GrantFiled: June 23, 2003Date of Patent: May 16, 2006Assignee: Pratt & Whitney Canada Corp.Inventor: Giuseppe Rago
