Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
305 words
A pyrotechnic assembly comprising: a launch tube; a pyrotechnic round positioned within said launch tube, said pyrotechnic round including a load of pyrotechnic material, a base member supporting said load of pyrotechnic material, a spring-holding member mounted on said base member on the opposite side of said base member from said load of pyrotechNic material, a biased spring member pivotally mounted on said spring holding member, one end of said spring member braced against said base member on the opposite side of said base member from said load of pyrotechnic material, a cup fixedly mounted on the other end of said spring member, said cup containing pyrotechnic ignition material; a piston member positioned within said launch tube adjacent said base member, said piston member serving to hold said cup in a cocked position with the closed end of said cup held against said base member on the opposite side of said base member from said load of pyrotechnic material, said piston member having a small opening therethrough communicating with the pyrotechnic ignition material in said cup; and a squib means positioned on the opposite side of said piston member from said cup and aligned with said small opening in said piston member for simultaneously asserting a force on said piston member to expel said piston member and said pyrotechnic round from said launch tube and igniting said pyrotechnic ignition material in said cup through said small opening in said piston member whereby upon expulsion of said pyrotechnic round and said piston member from said launch tube said biased spring member will act upon said cup containing the ignited pyrotechnic ignition material and pivotally rotate said cup up and back so that the ignited pyrotechnic ignition material will contact said load of pyrotechnic material of said pyrotechnic round thereby igniting said load of pyrotechnic round material.
Claim 2
Dependent Claim
305 words
A pyrotechnic assembly comprising: a launch tube; a pyrotechnic round positioned within said launch tube, said pyrotechnic round including a load of pyrotechnic material, a base member supporting said load of pyrotechnic material, a spring-holding member mounted on said base member on the opposite side of said base member from said load of pyrotechNic material, a biased spring member pivotally mounted on said spring holding member, one end of said spring member braced against said base member on the opposite side of said base member from said load of pyrotechnic material, a cup fixedly mounted on the other end of said spring member, said cup containing pyrotechnic ignition material; a piston member positioned within said launch tube adjacent said base member, said piston member serving to hold said cup in a cocked position with the closed end of said cup held against said base member on the opposite side of said base member from said load of pyrotechnic material, said piston member having a small opening therethrough communicating with the pyrotechnic ignition material in said cup; and a squib means positioned on the opposite side of said piston member from said cup and aligned with said small opening in said piston member for simultaneously asserting a force on said piston member to expel said piston member and said pyrotechnic round from said launch tube and igniting said pyrotechnic ignition material in said cup through said small opening in said piston member whereby upon expulsion of said pyrotechnic round and said piston member from said launch tube said biased spring member will act upon said cup containing the ignited pyrotechnic ignition material and pivotally rotate said cup up and back so that the ignited pyrotechnic ignition material will contact said load of pyrotechnic material of said pyrotechnic round thereby igniting said load of pyrotechnic round material.

Claim 8
Dependent Claim
17 words
The pyrotechnic assembly of claim 1 wherein said load of pyrotechnic material includes infrared radiating flash pellets.
Claim 9
Dependent Claim
17 words
The pyrotechnic assembly of claim 1 wherein said load of pyrotechnic material includes electromagnetic wave reflective material.
Claim 10
Dependent Claim
13 words
