Abstract
Abstract A burner in the form of a flame jet drill bit engine for liquid fuels is disclosed. The burner has particular utility in a flame jet drill and comprises an axially elongated body with a combustion chamber disposed therein. At least one flame jet nozzle is disposed through the body adjacent the bottom so as to communicate with the reaction chamber. At least one set of water or other liquid jet nozzles is also disposed on the bottom of the body which produce a pulsating water jet at extremely high velocities. The flame jet nozzle and the water jet nozzles are arranged and configured on the bottom of the body so as to be substantially parallel to the axis of the body. By the use of the combination of flame jets and water jets, a cutting means is produced which can cut through a wide range of amorphous and sedimentary rocks.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A rotatably mounted drill bit engine for liquid fuels having particular utility in a flame jet drill comprising an axially elongated body with a combustion chamber disposed therein, at least one flame jet nozzle opening through said body adjacent the bottom thereof so as to communicate with said combustion chamber, and a first set of liquid jet nozzles disposed on said engine adjacent said bottom thereof, said flame jet nozzle and said first set of liquid jet nozzles mounted substantially parallel to the axis of said body, said first set of liquid jet nozzles configured to direct a pulsating stream of liquid jet projectiles at high velocities such that as said engine is rotated, the area adjacent the bottom of said engine is subjected to flame jets and pulses of liquid projectiles at predetermined intervals whereby spalling of rock and the like is encouraged.
Claim 2
Dependent Claim
144 words
A rotatably mounted drill bit engine for liquid fuels having particular utility in a flame jet drill comprising an axially elongated body with a combustion chamber disposed therein, at least one flame jet nozzle opening through said body adjacent the bottom thereof so as to communicate with said combustion chamber, and a first set of liquid jet nozzles disposed on said engine adjacent said bottom thereof, said flame jet nozzle and said first set of liquid jet nozzles mounted substantially parallel to the axis of said body, said first set of liquid jet nozzles configured to direct a pulsating stream of liquid jet projectiles at high velocities such that as said engine is rotated, the area adjacent the bottom of said engine is subjected to flame jets and pulses of liquid projectiles at predetermined intervals whereby spalling of rock and the like is encouraged.
Claim 3
Dependent Claim
33 words
A rotatably mounted drill bit engine according to claim 1 wherein said liquid projectiles are pulsed out of said first set of liquid jet nozzles at the rate of one pulse per second.
Claim 4
Dependent Claim
23 words
A rotatably mounted drill bit engine according to claim 1 wherein said water projectiles have a velocity of approximately 2,000 to 5,000 meters/second.
Claim 5
Dependent Claim
50 words
The drill bit engine of claim 1 wherein, in addition thereto, at least one coolant wash opening is provided adjacent said bottom of said body, said coolant wash opening being directed in a generally upward direction so as to make an obtuse angle with respect to said flame jet nozzle.
Claim 6
Dependent Claim
52 words
The drill bit engine of claim 1 wherein said drill bit has two flame jet nozzles and first and second sets of liquid jet nozzles, said flame jet nozzles and said first and second sets of liquid jet nozzles arranged on said bottom of said body in an alternating and symmetrical configuration.
Claim 7
Dependent Claim

The drill bit engine of claim 1 wherein said drill bit has two flame jet nozzles, and first, second, and third sets of liquid jet nozzles, said flame jet nozzles and said first, second and third sets of liquid jet nozzles arranged on said bottom of said body in an alternating and symmetrical configuration.
Claim 9
Dependent Claim
29 words
The drill bit engine of claim 7 wherein each of said flame jet nozzles and each of said liquid jet nozzles extends radially along said bottom of said body.
Claim 10
Dependent Claim
38 words
The drill bit engine of claim 1 wherein said drill bit has a plurality of flame jet nozzles and a plurality of sets of liquid jet nozzles arranged on said bottom of said body adjacent the periphery thereof.
Claim 11
Dependent Claim
29 words
