Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
66 words
A METHOD OF PRODUCING AN INCENDIARY CASING FOR AN ORDNANCE DEVICE COMPRISING THE STEPS OF: INSERTING A TUBE OF PYROPHORIC MATERIAL INTO A TUBULAR MEMBER TO FORM A LINER THEREOF SAID PYROPHORIC MATERIAL BEING SUSCEPTIBLE OF EITHER HOT OR COLD FORMING, FORMING SAID TUBULAR MEMBER AND SAID TUBE OF PYROPHORIC MATERIAL INTO DESIRED FINAL CONFIGURATION AND HEAT-TREATING THE FINAL CONFIGURATION TO PRODUCE THE DESIRED PHYCISCAL CHARACTERISTICS.
Claim 2
Independent Claim
66 words
A METHOD OF PRODUCING AN INCENDIARY CASING FOR AN ORDNANCE DEVICE COMPRISING THE STEPS OF: INSERTING A TUBE OF PYROPHORIC MATERIAL INTO A TUBULAR MEMBER TO FORM A LINER THEREOF SAID PYROPHORIC MATERIAL BEING SUSCEPTIBLE OF EITHER HOT OR COLD FORMING, FORMING SAID TUBULAR MEMBER AND SAID TUBE OF PYROPHORIC MATERIAL INTO DESIRED FINAL CONFIGURATION AND HEAT-TREATING THE FINAL CONFIGURATION TO PRODUCE THE DESIRED PHYCISCAL CHARACTERISTICS.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said pyrophoric material is zirconium.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said tubular member is made of 1020 Steel.
Claim 5
Dependent Claim
34 words
The method of claim 1 wherein the heat treatment comprises the steps of: heating said tubular member and liner to a temperature of approximately 1600* to 1700* F.; and water quenching the heated Elements.
Claim 6
Independent Claim
77 words
A method of producing an incendiary casing for an ordnance device comprising the steps of: inserting a tube of zirconium into a tubular member of 1020 Steel to form a liner thereof; cold forming said tubular member and liner into a desired final configuration; heating said tubular member and liner to a temperature of approximately 1600* to 1700* F.; and water quenching said tubular member and liner to produce an incendiary casing having the desired physical characteristics.
Claim 7
Independent Claim
77 words
A method of producing an incendiary casing for an ordnance device comprising the steps of: inserting a tube of zirconium into a tubular member of 1020 Steel to form a liner thereof; cold forming said tubular member and liner into a desired final configuration; heating said tubular member and liner to a temperature of approximately 1600* to 1700* F.; and water quenching said tubular member and liner to produce an incendiary casing having the desired physical characteristics.
