Patent number: 10460714Abstract: Broadband acoustic absorbers may be capable providing good absorption performance between 0 and 3,000 Hz, and particularly below 1,000 Hz. Reeds may be incorporated in a single layer, multiple layers, or bundles. Such broadband acoustic absorbers may be applied for acoustic absorption in aircraft, spacecraft, residential and commercial buildings, vehicles, industrial environments, wind tunnels, or any other suitable environment or application where noise reduction is desired.Type: GrantFiled: February 6, 2017Date of Patent: October 29, 2019Assignee: United States of America as Represented by the Administrator of National Aeronautics and Space AdministrationInventors: Lisa Danielle Koch, Michael G. Jones, Peter J. Bonacuse, Christopher J. Miller, J. Chris Johnston, Maria A. Kuczmarski

Patent number: 8776374Abstract: A datum is created in an axle housing. A finished brake flange is welded to the axle housing with reference to the datum to make an axle sub-assembly. The axle sub-assembly is fixed to a first part of a machine. A finished spindle is supplied to a second part of the machine. The spindle is welded to the axle sub-assembly with reference to the datum. A dial indexing table is rotated to a first position. An axle is placed on the dial indexing table with its longitudinal axis oriented vertically. The dial indexing table is rotated to a second position, wherein the axle aligned with a CNC machine. A machining operation is performed on the axle with the CNC machine. The dial indexing table is rotated to a third position. The axle is removed from the dial indexing table. An axle and an apparatus for manufacturing an axle are described.Type: GrantFiled: April 30, 2010Date of Patent: July 15, 2014Assignee: Trimtool Ltd. O/A 1823912 Ontario Inc.Inventors: Chris Johnston, Robert Taves

Patent number: 8142137Abstract: A gas turbine vane to improve vane performance by addressing known failure mechanisms. A cooling circuit to the trailing edge of a vane airfoil is fed from the outer diameter platform, which prevents failure due to an oxidized and eroded airfoil trailing edge. The gas turbine includes an outer diameter platform, a hollow airfoil and an inner diameter platform with a plurality of cooling tubes extending radially through the airfoil. The cooling tubes are open at the outer diameter end and closed with covers at the inner diameter end. The inner diameter platform is also cooled and includes a meterplate for a portion of the cooling passageway and includes an undercut to improve thermal deflections of the inner diameter platform.Type: GrantFiled: November 26, 2008Date of Patent: March 27, 2012Assignee: Alstom Technology LtdInventors: Chris Johnston, Gary Bash, Tim teRiele, David Parker, James Page Strohl
