US Patent:

6799571, Oct 5, 2004

Filed:

Mar 31, 2003

Appl. No.:

10/401848

Inventors:

Nathaniel Hughes - Palm Springs CA
Leon Shaw - Santa Monica CA

Assignee:

Molecular Rotation, LLC - Concord CA

International Classification:

A61M 1500

US Classification:

12820312, 12820315

Abstract:

A medicinal delivery system utilizing a gaseous propellant source. The system includes a nozzle having an entrance and exit for passing medicinal powder material threrethrough. A conduit is also utilized to direct gaseous propellant to a place adjacent the nozzle exit. A flow shaper produces a vortex stream of the gaseous propellant which mixes with the medicinal powder material exiting the nozzle. The medicinal powder, gaseous propellant, and air are mixed in a vessel chamber and forced from the vessel chamber through an exit for use as a homogeneous aerosol.

Appl. No.:

10/410685

Inventors:

Nathaniel Hughes - Palm Springs CA, US
Leon Shaw - Santa Monica CA, US

International Classification:

G01F001/37

US Classification:

7386152

Abstract:

A mass flow meter device utilizing a housing having a wall portion forming a chamber with an entrance and exit for passing fluid through the same. A body is located within the chamber and is composed of a first conical portion, a second conical portion, and a cylindrical portion positioned intermediate the first and second conical portions. The body is held within the chamber in a standard or reverse direction. A first pressure probe or sensor measures the fluid pressure at the apex of the first conical portion while a second pressure probe or sensor obtains a second pressure measurement at the cylindrical portion of the body. The comparison of the first and second pressure measurements serves as an indication for the mass flow of fluid through the housing. The flow meter device may be adapted to existing fluid sources such as aerosol generators.

Assignee:

Fluid Energy Conversion, Inc. - Palm Springs CA

International Classification:

G01F 1/37

US Classification:

7386152

Abstract:

A flow metering apparatus possessing a housing with a chamber including and entrance and an exit for the passageway of fluid therethrough. A flow directing body is located in the chamber and includes first and second conical portions positioned on either side of a cylindrical portion. The body is supported in the chamber in a fixed manner. An orifice is located within the chamber upstream of the first conical portion of the body and is of a predetermined size to control the passage of fluid through the housing chamber. First and second sensors sense the dynamic pressures at the apex of the first conical portion and at a position between the body and a wall of the chamber.

Abstract:

A fluid reactor for facilitating mixing and/or chemical reaction and including an elongated cylindrical flow chamber having a first for receiving a flow of a first fluid, a second flow inlet through which a relatively low mass flow of a second fluid may be admitted to the chamber; and a cone-pi element disposed downstream of the second flow inlet and having an upstream conical portion with a leading apex generally facing the first flow inlet, an intervening cylindrical portion, and a downstream conical portion with a trailing apex generally facing the flow outlet, the cone-pi element being operable to produce cavitation and/or vortical flow within the flow stream to effectuate mixing and/or chemical interaction of the first fluid and the second fluid, and to deliver a mixed and/or reacted fluid from the flow outlet. The reactor may also include a catalytic component disposed within the chamber between the cone-pi element and the flow outlet for further influencing the interaction between the first fluid and the second fluid prior to its exit through the flow outlet.

Abstract:

A liquid medicament delivery system utilizing a carrier for a dose of liquid medicament. A conduit having an entrance and exit communicates with the carrier to permit the same to travel along the conduit. A propellant and the liquid medicament carried by the conduit are formed into a stable vortex eddy and passed to a mixing chamber where the medicament is delivered through an outflow aperture for use.

US Classification:

239405

Abstract:

A vortex is formed in fluid flowing through a flow passage from the inlet of the passage to its outlet. A bluff body is disposed at the outlet external to the passage to interrupt vortically flowing fluid. In one embodiment, the bluff body, which could comprise one or more frustums or discs, has a flat surface facing the outlet. In another embodiment, the body comprises a sphere. In a third embodiment, the body comprises a frustum and a sphere adjacent to each other on the flow axis.
