US Patent:

48201197, Apr 11, 1989

Filed:

May 23, 1988

Appl. No.:

7/197726

Inventors:

Michael J. Joyce - West Hartford CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F01D 1102

US Classification:

415172A

Abstract:

An inner turbine seal is formed of a full annular vane platform structure (32) and a full annulus seal land structure (60). These two structures are splined together (48, 50, 64) and piston ring (70) seals against leakage between the two structures. Radial differential growth between the structures is permitted. Vane platform structure (32) may therefore be designed to minimize stresses in the vane area (26, 28) while seal land structure (60) may be designed to minimize leakage through knife edge seals (22, 62).

International Classification:

B23K 2012

US Classification:

228113

Abstract:

A method for inertia welding axially symmetric articles while controlling the gripping force applied to the rotating component is described. A spacer inserted into the rotating headstock creates an alternative path for the axial force in excess of that required for causing gripping of the rotating component, and thus minimizes distortion of the inertia welded article. This is particularly useful in welding high strength superalloy articles, where extremely high axial forces are required to produce an adequate weld joint.

International Classification:

G01V 1/52
G01V 1/44

Abstract:

An embodiment of the present disclosure is an acoustic logging tool for determining a characteristic of a ground formation during a drilling operation. The acoustic logging tool includes a transmitter section that houses a transmitter that is configured to emit an acoustic signal and a receiver section spaced from the transmitter section along an axial direction. The receiver section includes a receiver that is configured to receive at least a portion of the acoustic signal. The acoustic logging tool also includes an isolator section positioned between the transmitter section and the receiver section along the axial direction.
