Patent number: 9267602Abstract: A seal assembly between a rotor and a stator is disclosed. In one embodiment, the seal assembly includes: a rotor; a stator positioned around the rotor; and a plurality of seal leaves positioned between the rotor and the stator, the plurality of seal leaves circumferentially stacked around the rotor to define a seal ring between the rotor and the stator, wherein gaps between adjacent seal leaves are partially filled, such that contact faces and residual gaps are between adjacent seal leaves, wherein the contact faces generate friction to dampen vibrations during operation. Such damping effects still allow the compliant motion of the seal leaves with minimal leaf vibration. Also, thicker and more resilient leaves may be applied with reduced leakage through the root gaps.Type: GrantFiled: November 19, 2012Date of Patent: February 23, 2016Assignee: General Electric CompanyInventors: Yuefeng Luo, William Edward Adis, Hrishikesh Vishvas Deo

Publication number: 20160010721Abstract: Engaging inclined surfaces of an inner ring and an outer ring create wedge action inducing an inward radial force as the rings are forced together longitudinally, holding the adjustor on a rotating body. An inner total arcuate length of each ring is smaller than an outer total arcuate length of a respective target body (inner ring for outer ring, rotating body for inner ring). Arcuate segments of each ring can have inner surfaces with radii of curvature equal to or smaller than that of the target body outer surface, and with a total arcuate length smaller than the circumference of the target body's outer surface.Type: ApplicationFiled: March 15, 2013Publication date: January 14, 2016Inventors: Douglas Arthur Lupe, William Edward Adis, Robert Edward Deallenbach, Mehmet Muhittin Dede, Andrzej Korabik, Noah Matthew Rothe

Publication number: 20150315717Abstract: Various embodiments include a sealed laminated metal structure. This laminated metal structure has a metal layer, where the metal layer has a first surface and an opposite second surface. A material is laminated on each of the first and second surfaces of the metal layer. In some cases, the laminated metal structure is removed from a larger laminated sheet of metal. The laminated metal structure is subjected to alternating current electrolytic deburring and cleaning to remove any burrs along the perimeter edge. After deburring and cleaning, a sealer, which is a phosphate compound, is deposited on the perimeter edge of the laminated metal structure where the metal is exposed using alternating current.Type: ApplicationFiled: July 13, 2015Publication date: November 5, 2015Inventors: Yuefeng Luo, William Edward Adis, Michael Lewis Jones
