Appl. No.:

10/231324

Inventors:

Joseph Unkyung Han - Irvine CA
Aleksandr V. Prokopenko - Bordentown NJ
Robert Michael Jensen - East Brunswick NJ

Assignee:

American Standard Inc. - Piscataway NJ

International Classification:

E03D 134

US Classification:

4391, 4415, 4378, 4379, 4380

Abstract:

A toilet includes a toilet bowl assembly having a toilet bowl and a trapway extending from the bottom of the toilet bowl to a sewage line. The toilet bowl has a rim channel provided along an upper perimeter portion thereof. In this toilet, the flush water flows through the rim channel in a path which is asymmetric and unidirectional along the entire perimeter portion thereof. The rim channel includes a plurality of rim openings distributed evenly along the perimeter of the rim channel. Flush water passing through the plurality of rim openings pre-wets the entire perimeter of the toilet bowl. The rim channel further includes a pair of water discharge slots which directs water directly into the toilet bowl in two powerful streams. The flush valve allowing passage of water from the water tank to the toilet bowl assembly is in the form of a valve inlet having a radiused port to generate greater energy throughput of the flush water.

International Classification:

B05B 710

US Classification:

239405, 239406, 239432, 239596

Abstract:

An injection system, injector, and associated method are provided for injecting and combusting combustion fluids in a combustion chamber. The system includes a faceplate that faces the combustion chamber and a plurality of injectors that extend through the faceplate. Each of the injectors has an injector body with an outlet side. A fuel bore extends from a fuel bore inlet to a fuel bore outlet located at the outlet side of the injector. Each injector also includes a swirler chamber with at least one inlet for receiving steam and an oxidizing fluid and an oxidizing fluid outlet located on the injector outlet side. A converging channel extends from the oxidizing fluid outlet to the swirler chamber, and the converging channel converges relative to the fuel bore so that steam and oxidizing fluid exiting the injector through the oxidizing fluid outlet impinge on a stream of fuel in the combustion chamber flowing from the fuel bore.

Assignee:

The Boeing Company - Chicago IL

International Classification:

F02C 320

US Classification:

60 39463, 60746

Abstract:

There are provided an injector and an associated method for injecting and mixing gases, comprising a carbonaceous fuel and oxygen, in a combustion chamber of a combustion device. The injector has jets, which can be used to separately inject different combustion fuels. The injector is compatible with combustion devices that inject only gases, for example, a reheater that provides initial combustion in a power generation cycle or a reheater that recombusts a discharged gas from a gas generator and turbine. Further, the injector defines an annular space through which a recycle gas can be injected into the combustion chamber to lower the combustion temperature.

James J. Fang - Chatsworth CA, US
Steven C. Fisher - Simi Valley CA, US
Robert J. Jensen - Thousand Oaks CA, US

Assignee:

Pratt & Whitney Rocketdyne, Inc. - Canoga Park CA

International Classification:

F02K 9/44

US Classification:

60204, 60258

Abstract:

There is provided an injector assembly having two or more oxidizer manifolds and/or two or more fuel manifolds for delivery of liquid propellants to a combustion chamber such that combustion instability is reduced or eliminated during throttling. Delivery of the oxidizer to the oxidizer manifolds is controlled by an oxidizer valve, which may comprise an integral valve. The oxidizer passes from the oxidizer manifolds into the oxidizer element and then into the combustion chamber. The multiple oxidizer manifolds allow the oxidizer to be provided through selective openings of the oxidizer element thus reducing the change in pressure drop across the oxidizer element to thereby reduce or eliminate combustion instability and other problems. Additionally, the injector assembly may also include a lift-off seal or a filler fluid source to fill any temporarily unused oxidizer manifolds with an oxidizer or filler fluid.

International Classification:

E04H012/00

US Classification:

052633000

Abstract:

A steel sub-purlin for use in roof construction, the sub-purlin being fabricated using metal roll forming techniques. The sub-purlin has an upper, angled portion, a lower angled portion, a vertical section connecting the upper and lower sections and vertical extensions from said upper and lower angled portions positioned in contact with the vertical section. The ends of sub-purlin are positioned on steel truss caps, the truss caps being used in place of conventional wood nailers.
