Appl. No.:

8/984743

Inventors:

James M. Weiler - Shakopee MN
Ryan A. Erickson - Farmington MN
Scott Darrell Isebrand - Minneapolis MN
Audrey Duane Preston - New Prague MN

Assignee:

MVE, Inc. - New Prague MN

International Classification:

F17C 702

US Classification:

62 501

Abstract:

A device for pressurizing a tank containing a supply of cryogenic liquid features a tubular enclosure disposed within the cryogenic liquid. The tubular enclosure features an opening in its bottom and is in communication with a pressure builder coil external to the tank. The vapor side of the pressure builder coil is in communication with the head space of the tank. An electric heater element is disposed in the bottom of the tubular enclosure. An insulating tube may optionally be disposed about the tubular enclosure. In addition, a ball may optionally be positioned adjacent the opening in the tubular enclosure so that a check valve is formed. The device fits through the tops of existing cryogenic tanks.

International Classification:

A61M 39/16
A61M 39/20

Abstract:

An article comprises a cap and a cover. The cap comprises an opening to an interior cavity, and has an inner surface defining the interior cavity and an outer surface. The cover is disposed within the interior cavity of the cap near the opening. The cover comprises a base having an inner surface facing the cap opening and an opposite outer surface. A sidewall of the cover extends from a perimeter of the base toward the cap opening. The sidewall has an outer surface facing the inner surface of the cap and an opposite inner surface. Micro features are provided on at least the inner surface of the sidewall. The cover is displaceable into the interior cavity of the cap.

International Classification:

B05B 7/08

Abstract:

Provided are nozzle assemblies for a spraying apparatus having an outer wall () having opposed inner and outer surfaces, a central aperture () extending through the outer wall, and a pair of auxiliary apertures () disposed on the outer wall (). Each auxiliary aperture is aligned along a respective auxiliary axis () and areas of the inner surface () of the outer wall () adjacent to the auxiliary apertures () are countersunk to define ledges () that are axially symmetric about the auxiliary axes (). These assemblies obviate problems associated with rotatable molding pins and also provide the unexpected advantage of providing axial alignment of the air flow profile as air is emitted from the auxiliary apertures.

International Classification:

G01N 27/22
G01N 33/00

Abstract:

A portable device includes an outer housing including an inlet port and a outer slot adapted to receive a vapor sensor card; an operating circuit disposed at least partially within the outer housing; a sensor holder at least partially disposed within the outer housing. The sensor holder includes: an inner housing including a gas intake chamber in downstream fluid communication with the inlet port. The gas intake chamber has a gas outlet in fluid communication with an inner slot retaining a sensor card socket for engaging the vapor sensor card. The sensor holder further comprises an electrical heater element, a fan, and a turbulent-flow-inducing member. The vapor sensor card comprises a sensor housing and a capacitive sensor element.
