Filed:

May 14, 2001

Appl. No.:

09/858033

Inventors:

Kenneth S. Wrye - Palos Verdes Estates CA
David W. Crowe - Palos Verdes Estates CA

Assignee:

Dow Imaging, Inc. - Paramount CA

International Classification:

G03D 302

US Classification:

396626

Abstract:

A recirculating system including a fluid supply tank with a plurality of flow sites for directing flow in and out of the tank along with a pump for driving the fluid flow and a set of fluid connectors providing fluid communication between such tank and a medical image processor which is particularly useful for sustaining prolonged operation of such processor during times of inadequate water supply.

Appl. No.:

8/581880

Inventors:

Mohamed Ahmed Hashish - Bellevue WA
David Arthur Crowe - Webster NY
Neil Dean Armstrong - Greece NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B24B 100
B24C 100

US Classification:

451 40

Abstract:

A method and apparatus for polishing a glass surface by directing an abrasive fluid through a nozzle exit maintained in close proximity to the surface. The fluid is constrained between the nozzle exit and the surface so the fluid flows radially outwardly tangential to the surface as it changes from high pressure in the nozzle to high velocity in the tangential direction. Polishing is controlled by regulating the proximity of the nozzle exit to the surface. Apparatus is provided including a nozzle extension for delivering the abrasive liquid to the surface and a nozzle body supporting the extension for relative movement automatically to balance the axial forces on the nozzle extension.

Appl. No.:

16/910805

Inventors:

- Seattle WA, US
David Crowe - Lake Forest Park WA, US

International Classification:

A24F 40/485
A24F 40/10
A24F 40/42
A24F 40/46

Abstract:

The present invention is directed towards a vaporization device that uses a vaporization media, The vaporization media used is an inherently non-porous solid having a plurality of frustal voids that are specially formed to provide improved capillary action and vaporization properties of high vaporization rate, tolerance to wide gamut of Extract types and viscosities, dramatic reduction in non-Extract media-emitted inhalable particulate or vapor, as well as collateral benefits such as fluid containment sealing, and manufacturability that are presently impossible with traditional vaporization media.

Inventors:

David Crowe - Seattle WA, US

International Classification:

A24C 5/54

International Classification:

H05B 3/00

Abstract:

The present invention is a method for vaporizing concentrate that will substantially eliminate general or localized burning of concentrate during the vaporization process and a vaporizer device adapted for carrying out the vaporization method. The vaporization method is based on heating concentrate that has been absorbed into a frit, preferably fritted glass. Fritted glass is characterized by open-pore interstices that allow free passage of fluid through the frit. It is commonly used as a filtering element, particularly in high-temperature applications. It is discovered that concentrate placed in contact with fritted glass is absorbed through capillary action. The concentrate at room temperature may not readily seep fully into fritted glass, as concentrate is heated its viscosity is reduced such that it is readily absorbed by the fritted glass and upon further heating the fritted glass and absorbed concentrate, the vapor of the concentrate is generated for inhalation.

Abstract:

The present invention is a method for vaporizing concentrate that will substantially eliminate general or localized burning of concentrate during the vaporization process and a device adapted for carrying out said method. The vaporization method is based on heating concentrate that has been absorbed into a frit, preferably fitted glass. Fritted glass is characterized by open-pore interstices that allow free passage of fluid through the frit. It is commonly used as a filtering element, particularly in high-temperature applications. It was discovered that concentrate placed in contact with fitted glass is absorbed through capillary action. Although room temperature concentrate may not readily seep fully into fritted glass, as concentrate is heated its viscosity is reduced such that it is readily absorbed by the fitted glass.
