Patent number: 9399922Abstract: Described are a gas turbine engine fan blade platform, related rotor assembly and gas turbine engine, as well as a method of assembling the same. The platform has a forward portion proximal to an axis of rotation, an aft portion, and a transition portion between the forward and aft portions. The forward portion has a forward interface surface facing axially forward, the aft portion has an aft interface surface facing radially outward, and the transition portion has at least one mounting feature. For the method of assembly, an aft support is installed on a fan disk and booster spool assembly. A plurality of fan blades are installed into a fan disk, followed by installing a fan platform between adjacent blades and securing the mounting features to the disk, thereby filling the annulus of the fan disk. Finally, a forward support is installed on the fan disk.Type: GrantFiled: December 31, 2012Date of Patent: July 26, 2016Assignee: General Electric CompanyInventors: Jorge Orlando Lamboy, Matthew Glen Gann, Nicholas Joseph Kray, Gerald Alexander Pauley, Daniel Allen Wilkin, II, Ming Xie

Publication number: 20110132684Abstract: A ladder brace assembly includes a U-shaped frame member having a base plate and a raised collar section positioned about a portion of an inner periphery thereof. The base plate includes, in a preferred embodiment, four holes for receiving screws, nails, pins, stakes, or other attachment means, which may be used to secure the brace assembly to a surface. Once the pair of ladder braces are in place, the shoes of the ladder may be placed within the U-shaped frames, so that the ladder shoes but up against the raised collar sections, thus preventing the ladder from sliding along the ground while the ladder is in use.Type: ApplicationFiled: December 8, 2009Publication date: June 9, 2011Inventor: David Allen Wilkins

Patent number: 7784532Abstract: Shunt tube flowpaths extending through swellable packers. A well system includes a packer assembly including a base pipe and an annular seal element which is swellable in response to contact with a selected fluid, and a shunt tube flowpath extending through the seal element for delivery of a slurry in a gravel packing operation. A swellable packer assembly includes a base pipe; a swellable annular seal element having a shunt tube flowpath extending through a swellable material; and a valve connected to the flowpath and positioned within the swellable material. Another well system comprises a packer assembly including a base pipe and an annular seal element which is swellable in response to contact with a selected fluid; a shunt tube flowpath extending through a swellable material of the seal element; and a connection between the flowpath and a shunt tube assembly, the connection being positioned within the swellable material.Type: GrantFiled: October 22, 2008Date of Patent: August 31, 2010Assignee: Halliburton Energy Services, Inc.Inventors: Alf K. Sevre, Tom R. Koloy, Allen Wilkins, Rutger Evers
