Appl. No.:

5/723912

Inventors:

Jack C. Swan - Boulder CO

Assignee:

Hanson Industries Inc. - Boulder CO

International Classification:

B29D 2700

US Classification:

264 26

Abstract:

Methods involving the use of high frequency heating means and temperature-compensating means to expand hollow, thermoplastic resinous microbeads in a controllable manner. The heat-expanded microbeads are suitable for use, for example, in providing viscous, flowable, pressure-compensating fitting materials or compositions.

Appl. No.:

5/723981

Inventors:

Jack C. Swan - Boulder CO

Assignee:

Hanson Industries Inc. - Boulder CO

International Classification:

A43B 720
A43B 1900
A43B 504

US Classification:

36 89

Abstract:

Viscous, flowable, pressure-compensating fitting materials or compositions retained within closures suitable for a variety of uses and applications, including fitting pads for footwear. More particularly, pressure-compensating fitting pads suitable for sports footwear or boots, such as ski boots, which provide proper and ready fitting, firm support, and comfort to desired portions of the foot of the wearer, including, for example, selected portions of side areas of the foot (including the ankle extremities). Footwear which includes such fitting pads as means for effectively providing proper and ready fitting, firm support, and comfort.

6/833892

Inventors:

Jack C. Swan - Boulder CO
Paolo Poggioli - Mirandola, IT

Assignee:

Cobe Laboratories, Inc. - Lakewood CO

International Classification:

B01D 1900

US Classification:

55193

Abstract:

A flow-through chamber for conveying blood including an elongated container having sides, a top and a bottom for mounting with its longitudinal axis in a vertical orientation, an inflow tube formed integrally with the container, extending vertically along a side of the container and entering the container through a chamber inlet at a flow direction transverse to the longitudinal axis and at a location spaced from the bottom of the chamber, and an outflow tube formed integrally with the chamber, extending vertically along a side of the container and entering the container at its bottom at a chamber outlet.

Appl. No.:

7/013353

Inventors:

Gary B. Heath - Aurora CO

Keith J. Manica - Littleton CO
Jack C. Swan - Boulder CO

Assignee:

Cobe Laboratories, Inc. - Lakewood CO

International Classification:

G01L 708
B01D 3500

US Classification:

73715

Abstract:

A fluid flow chamber cassette that can be mounted with either its front wall or rear wall against a supporting machine and has a flexible tube that extends from a sidewall and forms a loop that is symetrical about a loop axis that is transverse to the side wall so that the loop will be acted upon by a pump roller on the machine both when the front wall is against the machine and when the rear wall is against the machine. Also disclosed is automatically fixing the initial liquid levels and amounts of air in venous and arterial chambers of fluid flow transfer device apparatus by having the arterial chamber inlet enter the arterial chamber at a position higher than the arterial chamber outlet, having the venous chamber inlet enter the venous chamber at a position higher than the venous chamber outlet, and priming the apparatus by causing reverse flow, so that the liquid rises in the venous and arterial chambers to the level of the entrances of the inlets. Also disclosed is sensing pressure of fluid in a fluid flow chamber by placing an impermeable flexible diaphragm over a hole in a rigid wall of the fluid flow chamber, providing a second chamber on the other side of the diaphragm, and sensing the pressure in the second chamber.

US Classification:

210646

Abstract:

A fluid flow chamber cassette that can be mounted with either its front wall or rear wall against a supporting machine and has a flexible tube that extends from a sidewall and forms a loop that is symmetrical about a loop axis that is transverse to the side wall so that the loop will be acted upon by a pump roller on the machine both when the front wall is against the machine and when the rear wall is against the machine. Also disclosed is automatically fixing the initial liquid levels and amounts of air in venous and arterial chambers of fluid flow transfer device apparatus by having the arterial chamber inlet enter the arterial chamber at a position higher than the arterial chamber outlet, having the venous chamber inlet enter the venous chamber at a position higher than the venous chamber outlet, and priming the apparatus by causing reverse flow, so that the liquid rises in the venous and arterial chambers to the level of the entrances of the inlets.
