Abstract
Abstract This invention relates to a safety fuel which is characterized as a combustible high internal phase ratio emulsion which, although relatively non-ignitible, can be ignited under conventional ignition. This safety fuel is a high internal phase ratio emulsion having a combustible internal phase and an aqueous external phase containing sufficient volatile combustible materials in the external phase to ignite under conventional ignition conditions.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
26 words
A high internal phase ratio fuel in water emulsion, said emulsion containing sufficient volatile combustible materials in the exterior phase to render the emulsion more ignitible.
Claim 2
Dependent Claim
26 words
A high internal phase ratio fuel in water emulsion, said emulsion containing sufficient volatile combustible materials in the exterior phase to render the emulsion more ignitible.
Claim 3
Dependent Claim
13 words
The emulsion of claim 1 where the volatile combustible material is an alcohol.
Claim 4
Dependent Claim
131 words
The high internal phase ratio fuel in water emulsion of claim 1 which is a thixotropic, hydrocarbon-in-water emulsion fuel comprising (1) water, (2) an emulsifiable hydrocarbon, and (3) an emulsifying agent, said hydrocarbon being present in said emulsion fuel in an amount of at least 80% hydrocarbon by volume of the emulsion, said emulsion having the characteristics of a solid fuel when at rest and the characteristics of a liquid fuel when a force is exerted upon it, said emulsion tending to be non-adhesive, said emulsion having a critical shear point sufficient to permit pumping at high rates, and said emulsion having an apparent rest viscosity greater than about 1000 CPS and wherein the additional sufficient volatile combustible material is in the exterior aqueous phase to render the emulsion more ignitible.
Claim 5
Dependent Claim
18 words
Th emulsion of claim 3 where the volatile combustible material is methanol, ethanol, acetone or methyl ethyl ketone.
Claim 6
Dependent Claim
18 words
The emulsion of claim 1 where the volatile combustible material is methanol, ethanol, acetone or methyl ethyl ketone.
Claim 7
Dependent Claim
12 words
The emulsion of claim 2 where the volatile combustible material is methanol.
Claim 8
Dependent Claim
12 words
The emulsion of claim 2 where the volatile combustible material is ethanol.
Claim 9
Dependent Claim
12 words
The emulsion of claim 4 where the volatile combustible material is methanol.
Claim 10
Dependent Claim
12 words
The emulsion of claim 4 where the volatile combustible material is ethanol.
Claim 11
Dependent Claim
23 words
The emulsion of claim 1 wherein the volatile combustible material has a vapor pressure at room temperature at or above that of water.
Claim 12
Dependent Claim
23 words
The emulsion of claim 3 wherein the volatile combustible material has a vapor pressure at room temperature at or above that of water.
