US Patent:

6395200, May 28, 2002

Filed:

Dec 18, 2000

Appl. No.:

09/740210

Inventors:

Robert L. Crouch - Phoenix AZ
Darla D. Burchert - Surprise AZ

Assignee:

Fire-Trol Holdings, L.L.C. - Phoenix AZ

International Classification:

C09K 2102

US Classification:

252603, 252601

Abstract:

In a fugitive color fire retardant composition, the colorant initially colors the composition to a hue which contrasts with the hue of ground vegetation. A non-fugitive component is included in the colorant, in an amount sufficient to provide improved aerial visibility when the composition is first aerially applied to the vegetation. However, the amount of non-fugitive pigment is less than an amount which would prevent the composition from fading after application to an acceptable neutral hue.

Appl. No.:

6/159128

Inventors:

Robert L. Crouch - Phoenix AZ

Assignee:

Early California Industries, Inc. - Phoenix AZ

International Classification:

C23F 900

US Classification:

148 627

Abstract:

A method of inhibiting the fatigue of aluminum comprising the steps of immersing aluminum in an aqueous solution of a water soluble cyanide compound at room temperature and continuously maintaining the aluminum in contact with the aqueous solution. The aqueous solution is substantially free of chromium.

Appl. No.:

8/931907

Inventors:

Robert L. Crouch - Phoenix AZ

Assignee:

Fire-Trol Holdings, L.L.C. - Phoenix AZ

International Classification:

A62D 100

US Classification:

169 46

Abstract:

This invention relates to fire suppressant compositions and methods of preparing and using such compositions. The compositions consist of water, at least about 5% by weight of a fire retardant salt, which includes at least 1. 5% by weight of ammonium thiosulfate. These compositions may contain other optional functional components such as corrosion inhibitors, suspending agents, coloring agents, antimicrobials and stabilizers.

Christine Chang - Hsin-Chu, TW

Assignee:

Fire-Trol Holdings, L.L.C. - Phoenix AZ

International Classification:

A62D 100

US Classification:

106 1811

Abstract:

A gum-thickened fire retardant composition with improved stability and/or corrosion resistance contains a fire retardant salt, a gum thickener, an aqueous liquid carrier and at least one non-toxic water-soluble additive which is at least one carboxylic acid or salt thereof, having the structural formula ##STR1## wherein R is a substituted or unsubstituted phenyl group, or a substituted or unsubstituted carbon chain containing conjugated unsaturation, and X is hydrogen or a metal. The additive component is present in an amount effective to improve the stability of said composition and/or reduce the corrosivity of the composition to iron. Preferred compositions containing the combination of at least one compound in which R is a phenyl group, especially sodium benzoate, and at least one compound in which R is a carbon chain containing unconjugated unsaturation, especially sorbic acid.
