US Patent:

7089728, Aug 15, 2006

Filed:

Dec 17, 2003

Appl. No.:

10/738935

Inventors:

Michael Carney - York ME, US

Assignee:

Ingersoll-Rand Energy Systems Corporation - Portsmouth NH

International Classification:

F02C 3/00
F02C 7/36

US Classification:

60 39511, 148524

Abstract:

A power transfer assembly comprises a power turbine constructed of a nickel alloy; a gear shaft constructed of a low-carbon carburized gear material; and a transition portion between and welded to each of the power turbine and gear shaft. The nickel alloy may be welded to the transition portion by inertia welding, and the low-carbon carburized gear material may be welded to the transition portion by electron beam welding, for example. The power transfer assembly may be used in a microturbine engine, for example, to transfer rotation of a power turbine to an electric generator.

International Classification:

US Classification:

707200

Abstract:

A configuration parameter value access system used in connection with a computer system performs an access operation in connection with a configuration parameter in response to a configuration parameter access request from an applications program. Each configuration parameter access request includes a parameter class identifier, a filename and a parameter identifier. The configuration parameter value access system includes a plurality of configuration file path class lists, each of which has at least one entry, each entry defining a storage subsystem path in the computer system's storage subsystem. A file identifier generator tests successive entries of the configuration file path class list identified by the parameter class identifier to determine whether the storage subsystem contains a file which has the filename provided in the configuration parameter access request along a path defined by an entry. If so, a configuration parameter access module performs an access operation to retrieve or update the configuration parameter identified by the parameter identifier provided in the configuration parameter access request in the file identified by the file identifier generator. If the access operation is a retrieval operation, to retrieve the value of the configuration parameter, the configuration parameter value access system will retrieve the value of the parameter, if any, in the file identified by the file identifier generator.
