Abstract
Abstract A method for projecting a gelled liquid hydrocarbon, whereby a solution of a suitable compound in a normally liquid hydrocarbon is projected under pressure from a reservoir tank through an orifice, at which orifice a solution of a suitable compound is added under pressure to the first hydrocarbon solution, causing a gelling reaction between the two suitable compounds; and at which orifice the combined stream of thickened fuel is caused to be ignited.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A METHOD FOR GELLING A NORMALLY LIQUID HYDROCARBON COMPRISING ADMIXING SAID HYDROCARBON WITH AN ADDITIVE CAPABLE OF EFFECTING GELATION OF THE HYDROCARBON UPON REACTION WITH A SUITABLE GELLING INITIATOR; PLACING SAID GELLING INITIATORIN A SECOND CONTAINER; MIXING THE LIQUID FUEL AND ADDITIVE WITH THE GELLING INITIATOR IN THE BARREL OF A FLAME THROWER IN PROXIMITY TO THE ORIFICE OF THE BARREL; EJECTING THE HYDROCARBON AS A GELLED JET FROM SAID ORIFICE AND IGNITING THE FUEL AT A POINT BEYOND THE ORIFICE.
Claim 2
Independent Claim
81 words
A METHOD FOR GELLING A NORMALLY LIQUID HYDROCARBON COMPRISING ADMIXING SAID HYDROCARBON WITH AN ADDITIVE CAPABLE OF EFFECTING GELATION OF THE HYDROCARBON UPON REACTION WITH A SUITABLE GELLING INITIATOR; PLACING SAID GELLING INITIATORIN A SECOND CONTAINER; MIXING THE LIQUID FUEL AND ADDITIVE WITH THE GELLING INITIATOR IN THE BARREL OF A FLAME THROWER IN PROXIMITY TO THE ORIFICE OF THE BARREL; EJECTING THE HYDROCARBON AS A GELLED JET FROM SAID ORIFICE AND IGNITING THE FUEL AT A POINT BEYOND THE ORIFICE.
Claim 3
Dependent Claim
40 words
The method of claim 1, wherein said additive is an admixture of an amine having 1 to 30 carbon atoms and said gelling initiator is carbon dioxide in excess of 1 mole carbon dioxide per 2 moles of said amine.
Claim 4
Dependent Claim
14 words
The method of claim 2, wherein traces of water are added to said admixture.
