Abstract

The present invention is directed to a device for dispensing pyrophoric decoy particulates where the device is comprised of at least one payload vessel having a structural wall that forms a cavity for housing a plurality of pyrophoric particles. The structural wall has at least one opening to facilitate dispersal of the pyrophoric particles. The payload vessels are inserted inside a tubular sleeve and hermetically sealed inside the sleeve. Within the sleeve the at least one payload vessel is also in direct contact with an expulsion assembly that upon activation pushes the payload vessels and its pyrophoric contents out of the sleeve to react with the air.

First claim

What is claimed is:

1. A device for dispensing pyrophoric decoy particulate comprising:
a. a plurality of payload vessels, wherein each of the plurality of payload vessels is comprised of a structural wall forming a cavity, at least one opening on the structural wall, wherein the cavity comprises a plurality of pyrophoric particles;
b. an expulsion assembly in contact with one payload vessel of the plurality of payload vessels and further comprising a piston and an impulse cartridge;
c. a tubular sleeve surrounding the plurality of payload vessels and expulsion assembly; and
d. wherein the pyrophoric particles are hermetically sealed inside the sleeve with an end-cap and an ejection impulse of the expulsion assembly is transmitted through the plurality of payload vessels to pop-off the end-cap without compressing the plurality of pyrophoric particles.

2. The device of claim 1 , wherein the pyrophoric particles are comprised of pyrophoric foam.

3. The device of claim 1 , wherein the pyrophoric particles are loose granules or spheres.

4. The device of claim 1 , wherein the plurality of payload vessels are comprised of cardboard, plastic or metal.

5. The device of claim 1 , wherein the plurality of payload vessels are less than 6.

6. The device of claim 1 , wherein the structural wall is comprised of greater than 2 and less than 5 openings.
