International Classification:

F25B 21/02
US Classification:

62 362
Abstract:

The present invention provides a device for keeping medical materials, such as medicine, cool. The device allows for easy transportation provided infrequent access to electricity. The device incorporates a thermoelectric cooler (TEC) inside an insulated container. The TEC is in contact with a freezable material which is frozen when the TEC is electrically powered. Upon disconnect from electrical power, the freezable material provides passive cooling inside the container while the medical material is transported. This portable device helps patients to travel with their medicines confidently and safely.

The water filters or purifiers in the various housing may include, but are not limited to, a sediment filter, a carbon filter, a reverse osmosis filter, a forward osmosis filter, a chemical purifier (or purification sub-system), and/or an ultraviolet light water purifier (or purification sub-system).

Insulating Tubular Conduit Apparatus
view source
US Patent:

44444206, Apr 24, 1984
Filed:

Jun 1, 1983
Appl. No.:

6/499996
Inventors:

David M. McStravick - Houston TX
David V. Chenoweth - Houston TX
Assignee:

Baker International Corporation - Orange CA
International Classification:

F16L 918
US Classification:

285 47
Abstract:

A concentric insulating tubular conduit member for use in forming a conduit string, such as a tubing string in a subterranean well, is disclosed. Each individual concentric conduit comprises an outer tubing and an outwardly flared inner tubing welded to the outer tubing at the end of the flared section. The inner tubing member is formed from an initially straight cylindrical member having enlarged ends and, when outwardly flared, the flared ends, although stretched, have a thickness at least equal to the nominal thickness of the inner tubular member. Insulation may be contained within the annular cavity between the inner and outer tubing members and between inner and outer coupling members at the juncture between adjacent tubing sections.

Plastically Deformed Seals In Downhole Tools

US Patent:

45823499, Apr 15, 1986
Filed:

Jun 4, 1982
Appl. No.:

6/384839
Inventors:

David V. Chenoweth - Houston TX
David M. McStravick - Houston TX
Everett H. Smith - Houston TX
Assignee:

Baker Oil Tools, Inc. - Orange CA
International Classification:

F16L 1500
US Classification:

2853323
Abstract:

A metal-to-metal fluid tight seal configuration formed between two abutting tubular members for use in subterranean oil and gas wells is disclosed. A metal-to-metal fluid tight seal is utilized in a shear release expansion joint assembly mounted by means of an anchor seal assembly in a conventional downhole packer. Sealing engagement is provided by plastic deformation of an annular seal ring between two abutting tubular members which are less ductile than the seal ring. In the preferred embodiment the metal-to-metal fluid tight seal is formed between abutting box and pin tubular members and the plastic deformation of the circular ring occurs as the ring is received within a groove in one of the abutting tubular members which has a dissimilar profile in comparison to the cross-section of the circular ring. Plastic deformation occurs as the box and pin members are rotationally threaded together and a continuous fluid tight seal is maintained along surfaces of both tubular members.

Method Of Testing And Reconditioning Insulating Tubular Conduits

US Patent:

46736522, Jun 16, 1987
Filed:

Dec 1, 1986
Appl. No.:

6/936222
Inventors:

David M. McStravick - Houston TX
David V. Chenoweth - Lahaina HI
David M. Anderson - Whittier CA
Assignee:

Baker Oil Tools, Inc. - Orange CA
International Classification:

G01N 3318
US Classification:

436 2
Abstract:

A non-destructive on-site method of inspection, and testing of the insulating performance and reconditioning of a concentric insulating tubular conduit member is disclosed. The insulating tubular conduit members comprise concentric walled members with an intermediate annular insulating cavity defined therebetween. This non-destructive method of testing and inspection is based on a determination of the presence of an unacceptable level of moisture in the annular insulating cavity. Visual, auditory, electrical, and radioactive indicating means can be employed in accordance with the principles of this invention. The use of a vacuum pump to establish at least a partial vacuum in the annular insulating cavity in conjunction with the testing technique employed herein, additionally provides a means for reconditioning and improving the insulating performance of insulating tubular conduits and permits reassembly of a fluid transmission conduit in which each of the tubular conduit sections will have the desirable insulating capacity.

US Patent:

42102073, Jul 1, 1980
Filed:

Appl. No.:

6/020307
Inventors:

David M. McStravick - Houston TX
William M. Roberts - Deer Park TX
Assignee:

Baker International Corporation - Orange CA
International Classification:

E21B 4312
US Classification:

166330
Abstract:

Camway ball means are secured to the valve seat means and carriable in the camway slot means to pivot the valve head means as the head is rotated relative to its seat.

Seal Assembly With Energizing Mechanism

US Patent:

44114354, Oct 25, 1983
Filed:

Jun 15, 1981
Appl. No.:

6/273514
Inventors:

David M. McStravick - Houston TX
Assignee:

Baker International Corporation - Orange CA
International Classification:

F16J 1518
US Classification:

277 95
Abstract:

A seal assembly for downhole use in a subterranean well comprises inner and outer concentric annular sealing elements adapted to seal between an inner mandrel and an outer housing. The sealing elements are mounted in concentric annular recesses defined in relatively axially movable seal carrier members. In a preferred form, a spring loaded mechanism is provided to bias the seal carriers axially towards each other, thereby exerting an axially compressive force on the sealing elements between them. The compressive force is sufficient to expand the sealing elements against the sealing surfaces of the mandrel and outer housing, whereby non-elastomeric sealing elements, or seal elements which have become effectively non-elastomeric, can be utilized. Releasable latches are provided for attachment of the seal assembly to the associated housing.
