Appl. No.:

09/896355

Inventors:

William B. Watkins - Tequesta FL
Fred Honeycutt, Jr. - Palm Beach Garden FL
Robert Carroll - West Palm Beach FL
Donald R. Connell - Jupiter FL

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F04B 1700

US Classification:

417381, 422179, 60214

Abstract:

A catalyst bed assembly, comprising: an outer housing having an open interior, an inlet leading to the open interior, and an outlet from the open interior; a catalyst bed in the open interior; and a gap between the outer housing and the catalyst bed. The open interior receives material from the inlet. A portion of the material enters the catalyst bed to expose said material to a catalyst so that the material and the catalyst react and create heat within the catalyst bed assembly. A remainder of the material enters the gap between the outer housing and the catalyst bed to cool the catalyst bed assembly. The catalyst bed assembly could be part of a turbopump assembly. The turbopump assembly would further include a nozzle downstream of the outlet; a turbine downstream of the nozzle; and a pump driven by said turbine.

International Classification:

B01D 6138

US Classification:

21032178

Abstract:

Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness. The modules have a module case and bundle of a dense plurality of hollow fiber membranes contained in the case. One set of the fiber membranes in the bundle constitutes feed-fibers while another set of the fiber membranes in the bundle constitutes strip-fibers for use in contained liquid membrane separations. The feed-fibers and strip-fibers are disposed within the elongate module case in opposite generally wave-like paths such that the feed-fibers and strip-fibers converge at generally lengthwise-separated crossing regions within the module. This disposition of the feed-fibers and the strip-fibers minimizes the effective membrane thickness value of the module as compared to conventional contained liquid membrane modules thereby enhancing the efficacy of fluid separations.

William J. Egan - Lake Park FL

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

H01S 305

US Classification:

331 945G

Abstract:

A gas dynamic laser is formed having a combustor with a cylindrical combustion chamber, said combustion chamber is formed having a discharge opening at one end and primary injection means at the other end with a plurality of injector tubes for injecting a combustible mixture into said combustion chamber; an igniter is included for igniting said mixture; a secondary injection means is located adjacent the discharge opening and has a plurality of nozzle tubes for injecting an oxidizer, one nozzle tube being included for each injector tube; each cooperating nozzle tube and injector tube being axially aligned, with said nozzle tubes directing the oxidizer towards the injector tubes, a mixing chamber being located downstream of the secondary injection means for directing the gases to a nozzle array. The secondary injection means is constructed to have easy accessibility to the nozzle tubes.

Appl. No.:

5/653187

Inventors:

Sidney D. Parker - Lake Park FL
Robert G. Carroll - West Palm Beach FL
William L. Howell - North Palm Beach FL

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F02K 306
F02C 702

US Classification:

60204

Abstract:

A turbofan-ramjet engine is provided with optional duct burning in the turbofan mode. A core engine is provided with a first annular passage therearound for directing airflow around the inlet of the core engine. A second annular passage having a fan directs air flow into the inlet of the core engine and said first annular passage. A third annular passage extends around the first and second annular passage with the first and third annular passage each directing their flow into a common annular combustion chamber. Variable vanes are provided in the first and third annular passages to provide for blocking off the passage or acting as swirl vanes depending on mode of operation. Blocking vanes are also provided in the annular exhaust passage of the core engine. Coannular nozzles are provided with one located at the exhaust of the core engine and an outer one located aft of the common annular combustion chamber. Air bleed means are provided for providing a positive pressure behind vanes in the first or third annular passage when either one is placed in its flow-blocking position to prevent undesired propagation of flame into that passage.

Force - Washington DC

International Classification:

F02C 722

US Classification:

60739

Abstract:

A segmented, zoned fuel injection system for use within the entrance area of a combustor. The fuel injection system has a plurality of spray bars formed as part of closely-spaced apart segments. The spray bars are zoned to permit additional control of profile and flow rate of fuel injected into the combustor. This design permits radial profile control within the combustor, maintains higher efficiency at low fuel flows and easy replacement and/or maintenance of the components thereof.

8/556316

Inventors:

Tyler T. Evans - Palms Beach Gardens FL
Robert G. Carroll - West Palm Beach FL

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F23R 336

US Classification:

60 39463

Abstract:

A gas turbine engine combustor can operate on either liquid fuel or gaseous fuel while maintaining low levels of nitrous oxide emissions. An upstream end of each of a plurality of mixing tubes includes an external manifold that is supplied with gaseous fuel. The gaseous fuel is injected into the mixing tubes through a plurality of orifices with sufficient momentum to be uniformly distributed across the flow path of each mixing tube. The optimum fuel/air ratio for low nitrous oxide emissions does not exceed seventy five percent (75%) of the stoichiometric ratio for a given fuel.

US Classification:

21050023

Abstract:

The present invention is directed to a thermoplastic, unibody transfer device. This transfer device includes a membrane, and a housing surrounding the membrane. The housing includes a thermoplastic end cap and a thermoplastic shell. The end cap and shell are butt welded together. Additionally, there is a method of manufacturing with the aforementioned device. The method includes forming a bundle of a membrane, inserting the bundle into a shell, butt welding an end cap to the bundle and the shell so that the cap, bundle, and shell are fused together.
