Patent number: 8012273Abstract: A metallic article is produced by furnishing one or more nonmetallic precursor compound comprising the metallic constituent element(s), and chemically reducing the nonmetallic precursor compound(s) to produce an initial metallic particle, preferably having a size of no greater than about 0.070 inch, without melting the initial metallic particle. The initial metallic particle is thereafter melted and solidified to produce the metallic article. By this approach, the incidence of chemical defects in the metal article is minimized. The melted-and-solidified metal may be used in the as-cast form, or it may be converted to billet and further worked to the final form.Type: GrantFiled: June 28, 2010Date of Patent: September 6, 2011Assignee: General Electric CompanyInventors: Andrew P.

The stable-oxide-forming additive element forms a stable oxide in a titanium-based alloy. At least one additive element is present at a level greater than its room-temperature solid solubility limit in the titanium-base alloy.

Patent number: 7245701Abstract: A system and method for verifying the integrity of a DSL circuit on a shared telephone line. The invention uses the amplitude modulation principles to overcome the difficulty associated with a blocking capacitor that isolates a DSLAM on the DSL circuit from the rest of the shared telephone line. A transmitter of the invention mixes a high frequency carrier signal and a low frequency audio signal to produce an amplitude-modulated test signal. The amplitude modulated signal is supplied to the telephone line at a main distributing frame side of the blocking capacitor and is detected by a receiver at the DSLAM side of the blocking capacitor.Type: GrantFiled: September 20, 2004Date of Patent: July 17, 2007Assignee: AT&T Intellectual Property, Inc.Inventors: Gary Tennyson, Eric Ott Brockman

Publication number: 20060263231Abstract: A compositionally graded gas turbine disk is made by placing a cylindrically symmetric slip case concentrically into an interior of a cylindrically symmetric outer container. A first nickel-base superalloy powder is loaded into a radially inner first portion of the interior and a second nickel-base superalloy powder is loaded into a radially outer second portion of the interior. The slip case is removed so that the first nickel-base superalloy powder and the second nickel-base superalloy powder contact in the transition region and form a non-compacted powder mass. The non-compacted powder mass is processed into a gas turbine disk, typically by compacting the non-compacted powder mass to form a compacted powder mass, and thereafter heat treating the compacted powder mass.Type: ApplicationFiled: September 19, 2005Publication date: November 23, 2006Applicant: GENERAL ELECTRIC COMPANYInventors: Jon Groh, Eric Ott, Robert Schafrik, Daniel Krueger
