US Patent:

6422735, Jul 23, 2002

Filed:

Sep 20, 1999

Appl. No.:

09/399390

Inventors:

John Stewart Lang - San Pedro CA 90732

International Classification:

B01F 502

US Classification:

3661624, 3661752

Abstract:

A hydraulic jet flash mixer injects chemicals in the form of liquids, or slurries, or gases, into a fluid stream. The mixing system withdraws a side stream of fluid from a main fluid stream. The side stream is pressurized and directed through a convergent nozzle, producing a high-velocity jet. This jet is directed onto a deflector plate located on the center line of the conduit that carries the main fluid stream and is thereby diverted in the radial directions normal to the flow direction of the main fluid stream. The deflector is provided with an open port for injecting the chemicals that are to be mixed into the main stream. The even distribution of the injected chemicals is ensured by the hydrodynamic forces generated by the flow of the high-velocity jet over the deflector.

Abstract:

A invention mixes chemicals in the form of gases, into a fluid stream. The mixing system withdraws a side stream of fluid from a main fluid stream. The side stream is pressurized and directed through a convergent nozzle, producing a high-velocity jet. This jet is directed onto a deflector plate located on the center line of the conduit that carries the main fluid stream and is thereby diverted in the radial directions normal to the flow direction of the main fluid stream. The deflector is provided with a gas diffusion port for injecting the chemicals that are to be mixed into the main stream. The even distribution of the injected chemicals is ensured by the hydrodynamic forces generated by the flow of the high-velocity jet over the deflector. The invention is a continuation in part of application Ser. No. 09/399,390.

Appl. No.:

5/755835

Inventors:

John M. Lang - Bellevue WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

B65G 2510

US Classification:

198746

Abstract:

A shuttle conveyor for moving articles fore and aft on a cargo support, such as the baggage area in an aircraft cargo compartment, comprises a trolley assembly moved fore and aft by a cable means travelling in downwardly canted tracks and a means to raise and lower selectively one of two cargo-engaging pawls adapted to move cargo forward or aft of the compartment and operated by cable or chain operators.

Appl. No.:

6/709354

Inventors:

John S. Lang - Arcadia CA

Assignee:

James M. Montgomery, Consulting Engineers, Inc. - Pasadena CA

International Classification:

B01F 308

US Classification:

366137

Abstract:

Chemicals are injected and mixed in a fluid to be treated by hydraulically creating turbulence for mixing across the cross-section of the flow path of the fluid and injecting undiluted chemical into the turbulence.

International Classification:

B01F 518
B01F 504

US Classification:

366174

Abstract:

A hydraulic jet flash mixer in a system for treating waste water jets a secondary flow of water through a high-velocity nozzle towards a deflector assembly. In one embodiment, the deflector assembly is formed by a tip and a body, and the tip is spaced from, but spring biased toward, the body. The space between the tip and body acts as a nozzle for radially injecting a coagulant fed to the body by a pressurized supply line. In another embodiment, the deflector assembly is one piece, and the supply line is inside of and extends through the high-velocity nozzle such that coagulant is injected from a point between the nozzle and the deflector assembly.

Appl. No.:

5/864734

Inventors:

John M. Lang - Bellevue WA

Assignee:

The Boeing Company - Seattle WA

International Classification:

B65G 2504

US Classification:

198748

Abstract:

A shuttle conveyor for moving articles fore and aft on a cargo support such as the baggage area in an aircraft cargo compartment comprises a shuttle carriage assembly travelling in tracks moved fore and aft by a cable. A control mechanism is provided to raise and lower selectively one of two cargo engaging pawls mounted on the shuttle carriage. The pawls are adapted to move cargo forward or aft in the compartment and are operated by a cable or chain operator.

Appl. No.:

7/692584

Inventors:

Susumu Kawamura - San Gabriel CA
R. Rhodes Trussell - Pasadena CA
John S. Lang - Arcadia CA

Assignee:

James M. Montgomery Consulting Engineers, Inc. - Pasadena CA

International Classification:

B01D 2101
B01D 2128

US Classification:

210709

Abstract:

A flocculation system for water treatment facilities comprises a flocculation tank having a plurality of baffles which divide the interior of the flocculation tank into a plurality of compartments. The baffles are arranged to provide intercompartmental openings between adjacent upstream and downstream compartments, which, in turn, are arranged to provide a serpentine flow path through the flocculation tank. A mechanical mixer is mounted in each compartment for supplementing the mixing energy provided by the serpentine flow, particularly during periods of low water flow rates.

Appl. No.:

7/824909

Inventors:

John S. Lang - Arcadia CA

International Classification:

B01F 304

US Classification:

422224

Abstract:

A chemical reactor comprises packing media which promotes plug flow through the reactor. The packing media comprises a plurality of stacked plates, each plate comprising an array of upwardly protruding dimples separated by downwardly protruding dimples. The plates are stacked with the down dimples lying above the up dimples of the plates below to thereby form rows of compartments. The up dimples comprise four transfer ports to provide even flow of fluid from a compartment in one row to each of the adjacent compartments in the adjacent rows. The method achieves plug flow in the reactor and causes two fluids to mix by the use of turbulence and shear at each transfer port.
