Filed:

Apr 3, 2001

Appl. No.:

09/824132

Inventors:

Mark M. Stephenson - New Carlisle OH, US
Steven A. Walters - Dayton OH, US

Assignee:

Science Applications International Corporation - San Diego CA

International Classification:

G06F 15/16

US Classification:

709227, 709218

Abstract:

A system and method for exchanging information between clients separated by firewalls is disclosed. A server may receive the information as posted through a browser client from beyond a first firewall and relay it to another client beyond a second firewall without lowering the security levels of the firewalls.

Filed:

Nov 12, 1992

Appl. No.:

7/974637

Inventors:

Ivan H. Peterson - Hamilton OH
Steven A. Walters - Cincinnati OH
Dale E. Hampshire - Mason OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16M 1300

US Classification:

248550

Abstract:

A support system for coupling elements of different temperatures while reducing thermal and dynamic stress. The support system couples a fuel manifold to a combustor in a gas turbine engine and includes first and second elongated brackets connected, respectively, to the combustor and to the fuel manifold. Distal ends of each of the brackets are positioned in overlapping relationship. A slot is formed in one of the overlapping distal ends and an aperture formed in the other aligned generally with the slot. A fastener extends through the aperture and slot compressing the ends against each other with a preselected force such that the ends cannot separate but can exhibit a sliding motion in the slot direction. The compressive force is controlled by a spring member positioned between one end of the fastener and an adjacent surface of one of the first and second brackets. A second disk fits around the stud similar to a large flat washer and the spring member fits around the stud between the two disks.

Appl. No.:

8/338063

Inventors:

Michael A. Umney - Mason OH
Steven A. Walters - Canton MI
Christopher R. Koss - West Chester OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F16L 1706

US Classification:

285367

Abstract:

A coupling assembly for fluid carrying tubes in a gas turbine engine include first and second fittings fixedly joined to respective ones of the tubes. The first and second fittings include respective first and second mating flanges which are joined together by a clamping band which is adjustable therearound. The first and second flanges include oppositely facing first and second flat faces, with the first flange having a counterbore extending inwardly from the first face, and the second flange having a pilot tube extending outwardly therefrom for being inserted into the counterbore. An annular seal is disposed between the first and second fittings for providing a leak-proof coupling upon clamping together of the two fittings by the clamping band.

Appl. No.:

8/093912

Inventors:

Steven A. Walters - Fairfield OH

Assignee:

General Electric Company - Cincinnati OH

International Classification:

F02C 720

US Classification:

60 3931

Abstract:

A variable friction force damper utilizes geometric variations in a sliding surface to vary the frictional force. In particular, variation in thickness of the member on which the sliding surface is formed produces a corresponding variation in the displacement of a compression spring. This variation in spring displacement produces a variation in the compression force exerted by the spring, i. e. , the force with which the sliding member is pressed against the sliding surface. This in turn causes a variation in the frictional force which the sliding surface exerts on the sliding member. The result is a variable friction force damper having a variable damping capability which allows a controlled response at variable input levels.
