Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20060180253, Method for manufacture of microcrystalline nitrocellulose.

1. A composition comprising microcrystalline nitrocellulose.

2. The composition of claim 1 wherein said microcrystalline nitrocellulose is in pellet form.

3. The composition of claim 1 wherein said microcrystalline nitrocellulose is compacted into a cylindrical form to axially receive a projectile at a first end, and to axially receive a primer means at a second end, said second end opposite said first end.

4. A high-nitrogen fuel comprising between 10 to 98 percent microcrystalline nitrocellulose by weight.

5. The high-nitrogen fuel of claim 4 further including at least one additive selected from a set of additives including crystalline salts, crystalline oxidizers, carbonaceous fuels, and powdered metals.

6. The high-nitrogen fuel of claim 5 wherein said crystalline salts comprise between 2 to 20 percent of the high-nitrogen fuel by weight.

7. The high-nitrogen fuel of claim 5 wherein said crystalline oxidizer comprises between 2 to 40 percent of the high-nitrogen fuel by weight.

8. The high-nitrogen fuel of claim 5 wherein said carbonaceous fuel comprises between 1 to 10 percent of the high-nitrogen fuel by weight.

9. A process for producing microcrystalline nitrocellulose, comprising nitrating microcrystalline cellulose particles.

10. The process of claim 9 for producing microcrystalline nitrocellulose further including the step of producing said microcrystalline cellulose particles from the hydrolytic degradation of cellulose.

11. The process of claim 9 for producing microcrystalline nitrocellulose wherein said microcrystalline cellulose particles are nitrated with an acidic solution including at least nitric acid.

12. The process of claim 11 for producing microcrystalline nitrocellulose wherein said microcrystalline cellulose particles are nitrated with an acidic solution including at least sulfuric acid.

13. The process of claim 9 for producing microcrystalline nitrocellulose further including the step of compacting said nitrated microcrystalline cellulose into pellets.

14. The process of claim 9 for producing microcrystalline nitrocellulose further including the step of regulating said nitration of said microcrystalline cellulose particles by selecting a size of said microcrystalline cellulose particles for nitration.

15. A process for producing a pyrotechnic composition, comprising: nitrating microcrystalline cellulose to produce microcrystalline nitrocellulose; and combining said microcrystalline nitrocellulose with at least one additive selected from a set of additives including crystalline salts, crystalline oxidizers, carbonaceous materials, and powdered metals.

16. The process of claim 15 for producing a pyrotechnic composition further including the step of compacting said combination of microcrystalline nitrocellulose and said at least one additive into pellet form.
