Appl. No.:

09/837811

Inventors:

Joseph E. Wolfe - Richboro PA

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

A62C 502

US Classification:

239 8, 239310, 239312, 239315, 239318, 239548, 169 43, 169 44, 169 14, 169 15

Abstract:

An apparatus for creating a fine liquid mist includes a container capable of holding fluid; one of a perforated basket and a porous bag disposed in the container; a liquid supply connector connected to the container; a mixing chamber connected to the container; and at least one convergent/divergent nozzle connected to the mixing chamber. A method of forming an effervescent fine liquid mist includes mixing liquid and chemical reactant to form non-toxic, noncombustible gas bubbles; mixing the liquid and the gas bubbles to form a two-phase fluid flow; and directing the two-phase fluid flow through at least one convergent/divergent nozzle.

Abstract:

An apparatus for mixing two or more fluids, gases or other substances and conveying said fluids, gases or other substances through a convergent-divergent (C-D) nozzle to produce a highly atomized output flow that is adjustable from no atomization to full atomization, said preferred embodiment of said apparatus having a housing and a nose portion and a gripping portion, the housing including an outer conduit and an inner conduit, the outer and inner conduits positioned and arranged to convey fluids, gases and other substances from an entry point to an exit point and into the entry end of a C-D nozzle and through said C-D nozzle to produce an output flow. The location of the outer conduit, inner conduit and C-D nozzle may be adjusted to vary the output flow from no atomization to full atomization. The pressure and flow rate in each conduit may also be separately adjusted to obtain the desired output flow.

International Classification:

B05B 7/12

US Classification:

239413000, 239418000, 239304000, 239407000

Abstract:

An apparatus to amalgamate substances which includes at least two substance holding tanks, an inert gas tank, an amalgamation mixing chamber, and a nozzle. The inert gas tank is in fluid communication with the at least two substance holding tanks such that when actuated, inert gas will further pressurize substances contained in the at least two substance holding tanks. The amalgamation mixing chamber is in fluid communication with the at least two substance holding tanks such that when actuated, the substances in the at least two substance holding tanks enter and mix in the amalgamation mixing chamber. The nozzle is in fluid communication with the amalgamation mixing chamber such that when actuated, the mixed substances in the amalgamated mixing chamber are discharged from the nozzle.

International Classification:

B05B 7/04
B05B 7/12
B05B 7/06

US Classification:

239398, 2394175, 2394245

Abstract:

The fluids mixing nozzle includes a mixing chamber, a first fluid supply port, a second fluid supply port, a nozzle port and a converging-diverging nozzle. The mixing chamber includes a first side and a second side. The first fluid supply port flowably communicates with the mixing chamber. The second fluid supply port flowably communicates with the mixing chamber. The first fluid supply port and the second fluid supply port are disposed on the first side of the mixing chamber. The nozzle port is disposed on the second side of the mixing chamber and allows fluid communication between the mixing chamber and the converging-diverging nozzle. The converging-diverging nozzle includes a nozzle intake section, a convergent mixing flow zone, a throat section, a divergent mixing flow zone and a nozzle exit section.

Appl. No.:

8/308335

Inventors:

Joseph E. Wolfe - Southampton PA

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

A62C 3102
B05B 704

US Classification:

239 8

Abstract:

A convergent/divergent gas nozzle atomizes a liquid provided through a lid delivery tube having an aperture which is centered within a central gas conduit of an upstream mixing block connected to the nozzle. The aperture of the liquid delivery tube is located just upstream of a narrowed throat of the nozzle. The throat of the nozzle is dimensioned such that its inside diameter is equal to the outside diameter of the liquid injector tube. A spout is located at the discharge end of the nozzle which has an inside diameter equal to two times the inside diameter of the throat. This nozzle displays superior performance, providing an extremely fine mist having high momentum. This nozzle is particularly well-suited to fire extinguishment.
