Filed:

Apr 23, 2002

Appl. No.:

10/128803

Inventors:

Roger A. Bown - Seattle WA
Michael L. Watts - Tacoma WA

Assignee:

The Boeing Company - Chicago IL

International Classification:

B24B 100

US Classification:

451 51, 451 57

Abstract:

A portable precision flange grinder grinds a flange on a duct. The flange has an axis, a radius, and a periphery. A mount mounts the grinder within the duct. The mount attaches to openings at ends of the duct. A grinding wheel grinds a flange on a duct and arranged to rotate along a periphery of the flange. A first linkage translates the grinding wheel along an axis of the flange to bring the grinding wheel laterally in grinding contact with the flange. The first linkage engages with the mount along an axis of the flange. A second linkage translates the grinding wheel along a radius of the flange bringing the grinding wheel radially in grinding contact with the flange. The second linkage attaches to the first linkage. A bearing assembly rotates the grinding wheel about the periphery of the flange. The bearing assembly is attached to the first linkage.

Appl. No.:

11/536431

Inventors:

James D. Cotton - Issaquah WA, US
William L. Merrick - Des Moines WA, US
Michael L. Watts - Tacoma WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

C22F 1/18

US Classification:

148670, 148671

Abstract:

A method is provided for improving the machinability of a titanium alloy includes heating the alloy at a temperature and time period that imparts to the alloy a microstructure having between about 10 and 15 vol. % alpha phase in a beta phase matrix. According to one embodiment, the alloy is thereafter annealed at a temperature lower than the temperature for the initial heating step, and for a duration that is longer than the time period for the initial heating step.

Michael Watts - Seattle WA, US

Assignee:

COCHRAN, INC. - Seattle WA

International Classification:

H02J 3/18

US Classification:

307 99

Abstract:

A shore power system includes a primary switchgear, a secondary switchgear, a dual output power transformer disposed in electrical communication between the primary switchgear and the secondary switchgear, a grounding switch section, and a vessel connector assembly. The shore power system further includes an automation and control system for automating and/or controlling the delivery of power to the vessel from a source of power, such as a medium voltage power source. In embodiments of the present disclosure, the medium voltage power source may be from the power grid or may be from a discrete power generation station.

International Classification:

B21D 3908

US Classification:

72 42

Abstract:

A hole is formed in a high-strength steel part and a lubricant consisting essentially of one or more metal powders, preferably of nickel or molybdenum; a metal powder which is more reactive than the steel of the workpiece such as zinc; and an organic medium is applied. A forming mandrel having a generally cylindrical shape with a frustoconical portion on either end is centered over the hole. The mandrel is pushed through the hole at a rate such that the steel adjacent the hole is coldworked and its microstructure is transformed from an austenitic to a normal tempered martensitic structure.
