US Classification:

210685, 210281, 210284, 210289, 2105021

Abstract:

An ion exchange apparatus includes at least one fluid passage that extends between an inlet and an outlet for transporting a fluid having ions therein. At least one cartridge includes an ion exchange material and the cartridge has an ion removal rate of removing the ions from the fluid that varies in response to a concentration of the ions in the fluid.

Appl. No.:

11/220159

Inventors:

Barbara M. Peyton - Windsor CT, US
John W. Steele - Hartford CT, US

Assignee:

Hamilton Sundstrand Space Systems International, Inc. - Windsor Locks CT

International Classification:

B05D 1/00
C09D 5/14

US Classification:

424405, 106 1505, 106 145

Abstract:

An antimicrobial coating slurry includes about 15. 5 wt % of a wetting agent, about 6. 0 wt % of an insolubilizer, about 1. 1 wt % of a biocide agent, and about 7. 8 wt % of an inorganic material that includes lithium oxide and the balance water. The slurry is applied to a heat exchanger surface, cured, and washed to form a hydrophilic coating that includes lithium silicate. The hydrophilic coating provides improved moisture wicking and a reduced dissolution rate of biocide, which is held within a lithium silicate matrix.

Abstract:

An aqueous-based coolant for cooling and reducing corrosion potential in applications having high aluminum or nickel surface area to coolant volume ratios has a pH between 8 and 9 and includes about 35 weight % to about 65 weight % propylene glycol, about 1. 0 weight % to about 4. 0 weight % 2-ethylhexanoic acid, about 0. 25 weight % to about 1. 0 weight % sebacic acid, about 0. 25 weight % to about 1. 0 weight % benzoic acid and about 0. 03 weight % to about 0. 1 weight % molybdate oxyanion. A cooling system includes an aluminum or nickel surface and the aqueous-based coolant. A method of cooling a component surface containing aluminum or nickel includes delivering the aqueous-based coolant to the component surface and cooling the component surface with the aqueous-based coolant.

Oct 15, 2004

Appl. No.:

10/966654

Inventors:

Barbara Peyton - Windsor CT, US
John Steele - New Hartford CT, US

International Classification:

G01N 21/00

US Classification:

436165000

Abstract:

A chemical measuring apparatus and method that include a flexible sample bag for unmasking and measuring an amount of a chemical in a sample while under microgravity conditions. The sample includes a biocide that masks the presence of the chemical in the sample. The flexible sample bag includes first and second fluidly connectable chambers. The first chamber includes a pH adjuster for adjusting the pH of the sample, thereby unmasking the presence of a chemical in the sample. The second chamber includes a chemical measuring device and indicator for measuring the amount of the chemical in the sample.

US Classification:

205740, 210763, 204232, 204240

Abstract:

A method for controlling microbial growth in potable water stored in a vessel having a metallic surface includes heating the metallic surface to a temperature between about 480 C. (900 F.) and about 870 C. (1600 F.), exposing the metallic surface to oxygen during heating to oxidize potential reduction sites on the metallic surface and charging potable water containing silver ions to the vessel. A vessel having a metallic surface is prepared for long-term storage of potable water containing silver ions by heating the metallic surface to a temperature between about 480 C. (900 F.) and about 870 C. (1600 F.) and exposing the metallic surface to oxygen during heating to oxidize electropositive metals on the metallic surface or by treating the metallic surface with an aqueous solution containing on oxidizing agent to oxidize potential reduction sites on the metallic surface.

International Classification:

C23C 28/00
B32B 15/04

US Classification:

148276, 148400

Abstract:

The sublimation capability of a porous metal plate used in a sublimator is maintained by heating the porous metal plate at an elevated temperature in a flowing stream of oxygen for an extended period of time to form an oxidized surface. A short chain molecule, such as citric acid, is attached to the oxidized surface having multiple functional carboxylate groups and no hydrophobic tail.
