Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
82 words
A fuel composition comprising a major amount of a hydrocarbon base fuel, up to about 20% by volume of a supplemental fuel component having a research blending octane number in excess of about 100 and at least about 1% by volume of a polyether more soluble in said hydrocarbon base fuel than in water, said fuel composition being capable of tolerating water in an amount greater than the tolerance of a blend of the hydrocarbon base fuel and the supplemental fuel component.
Claim 2
Dependent Claim
82 words
A fuel composition comprising a major amount of a hydrocarbon base fuel, up to about 20% by volume of a supplemental fuel component having a research blending octane number in excess of about 100 and at least about 1% by volume of a polyether more soluble in said hydrocarbon base fuel than in water, said fuel composition being capable of tolerating water in an amount greater than the tolerance of a blend of the hydrocarbon base fuel and the supplemental fuel component.
Claim 3
Dependent Claim
22 words
The fuel composition of claim 1 wherein said polyether is present in an amount of from about 1 to 15% by volume.
Claim 4
Dependent Claim

Claim 10
Independent Claim
81 words
A method of preparing a fuel composition which comprises blending a major amount of a hydrocarbon base fuel with up to about 20% by volume of a supplemental fuel component having a research blending octane number in excess of about 100 and containing water and adding thereto at least about 1% by volume of a polyether more soluble in the hydrocarbon base fuel than in water, said polyether being present in an amount sufficient to provide a single phase fuel composition.
Claim 11
Independent Claim
81 words
A method of preparing a fuel composition which comprises blending a major amount of a hydrocarbon base fuel with up to about 20% by volume of a supplemental fuel component having a research blending octane number in excess of about 100 and containing water and adding thereto at least about 1% by volume of a polyether more soluble in the hydrocarbon base fuel than in water, said polyether being present in an amount sufficient to provide a single phase fuel composition.
Claim 12
Dependent Claim
51 words
A fuel composition comprising a major amount of a hydrocarbon base fuel and at least about 1% by volume of a polyether more soluble in the hydrocarbon base fuel than in water, said fuel composition being capable of tolerating water in an amount greater than that of the hydrocarbon base fuel.
Claim 13
Dependent Claim
51 words
A fuel composition comprising a major amount of a hydrocarbon base fuel and at least about 1% by volume of a polyether more soluble in the hydrocarbon base fuel than in water, said fuel composition being capable of tolerating water in an amount greater than that of the hydrocarbon base fuel.
Claim 14
Dependent Claim
81 words
An additive for imparting increased water tolerance to a fuel composition containing a hydrocarbon base fuel and having a certain, anticipated amount of water comprising a mixture of a supplemental fuel component having a research blending octane number in excess of about 100 and a polyether more soluble in a hydrocarbon base fuel than in water, the relative amounts of said supplemental fuel component and said polyether being capable of providing a single phase composition upon addition to said fuel composition.
Claim 15
Dependent Claim
81 words
An additive for imparting increased water tolerance to a fuel composition containing a hydrocarbon base fuel and having a certain, anticipated amount of water comprising a mixture of a supplemental fuel component having a research blending octane number in excess of about 100 and a polyether more soluble in a hydrocarbon base fuel than in water, the relative amounts of said supplemental fuel component and said polyether being capable of providing a single phase composition upon addition to said fuel composition.
