Patent number: 8327752Abstract: Disclosed is an actuator that includes a cylinder having an input port, a piston disposed at least partially inside of the cylinder, and one or more piston rings disposed in a circumferential piston ring groove or grooves. The actuator also includes at least one spring, inserted into the circumferential piston ring groove adjacent to the one or more piston rings and a high pressure side of said piston ring. The spring preloads the one or more piston rings to seal between a low pressure face of the one or more piston rings and a low pressure face of the circumferential piston ring groove. The invention also includes a method for moving an adjustable seal in a radial direction using the piston-ring sealed actuator. The method includes moving the adjustable seal in an axial direction, breaking a primary axial contact between the adjustable seal and a primary sealing face.Type: GrantFiled: October 27, 2006Date of Patent: December 11, 2012Assignee: General Electric CompanyInventors: Kripa Kiran Varanasi, Shorya Awtar, Frederick George Baily, Mark Edward Burnett, Farshad Ghasripoor, Imdad Imam, Norman Arnold Turnquist

Patent number: 8251659Abstract: An insert and method for altering a through-hole in a body, such as a steam balance hole in a steam turbine rotor wheel. The insert has a body with oppositely-disposed first and second ends, a flange radially extending from the second end of the body, and an outer surface at a perimeter of the body between the first end and the flange. A first bore within the body defines a first opening at the first end, and the first bore and outer surface of the body cooperate to define therebetween a wall capable of being plastically deformed in a radially outward direction. A second bore within the body communicates with the first bore and has a smaller cross-section than the first bore. The installation method entails installing the insert in a through-hole and flaring the wall to clamp the axial thickness of the body between the flange and flared wall of the insert.Type: GrantFiled: November 26, 2008Date of Patent: August 28, 2012Assignee: General Electric CompanyInventors: Nicholas Tisenchek, Frederick George Baily, John Matthew Sassatelli, James Royce Howes

Patent number: 7549834Abstract: An actuation pressure control system effects actuation of adjustable seal segments between stationary and rotating turbomachinery members. At least one actuator is coupled with each of the adjustable seal segments and controls a position of the seal segments, respectively.

Patent number: 6669443Abstract: In a steam turbine, a combined brush and labyrinth seal is provided between a diaphragm web and a radially outwardly projecting platform between axially adjacent wheels on the rotor. The brush seal is located upstream of the labyrinth seal teeth. The platform has at least one and preferably a pair of flanges or fins projecting in opposite axial directions adjacent radial outer ends of the platform. Non-uniform heat distribution resulting from the frictional contact between the bristles of the brush seal and a sealing surface on the platform along the rotor surface affecting rotor dynamics is thereby eliminated or minimized.Type: GrantFiled: November 16, 2001Date of Patent: December 30, 2003Assignee: General Electric CompanyInventors: Mark Edward Burnett, Christopher Edward Wolfe, Frederick George Baily, Norman Arnold Turnquist, Bruce William Brisson, David Alan Caruso
