Abstract
Abstract A bullet-proof armor formed of a pad made of a number of loose sheets woven of heavy gauge, linearly oriented nylon threads, the pad being enclosed within a cloth envelope, and means for holding the envelope containing the pad upon the object to be protected. The sheets are treated by subjecting them to super-cooling in a cryogenic atmosphere to thereby increase their impact resistance capabilities.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A bullet-proof protective armor comprising: a relatively flexible pad formed of a number of sheets, such as one to two dozen sheets, of cloth arranged in face to face relationship and secured together along one edge, with the sheets being substantially free of positive securement together between their opposite edge portions for relative flexing of each of the sheets; said cloth being of a tightly woven material formed of heavy, nylon thread, such as roughly on the order of 1,050 denier; and means for positioning and holding the pad upon an object to be protected, for stopping bullets and the like missiles impacted against said pad.
Claim 2
Dependent Claim
106 words
A bullet-proof protective armor comprising: a relatively flexible pad formed of a number of sheets, such as one to two dozen sheets, of cloth arranged in face to face relationship and secured together along one edge, with the sheets being substantially free of positive securement together between their opposite edge portions for relative flexing of each of the sheets; said cloth being of a tightly woven material formed of heavy, nylon thread, such as roughly on the order of 1,050 denier; and means for positioning and holding the pad upon an object to be protected, for stopping bullets and the like missiles impacted against said pad.
Claim 3
Dependent Claim
53 words
An armor as defined in claim 1, and wherein the nylon material has a molecular structure resulting from linearly orienting the molecules and then subjecting the material to a cryogenic, super-cold temperature, relatively near absolute zero for a relatively short period of time, such as on the order of roughly a few hours.
Claim 4
Dependent Claim
91 words
An armor as defined in claim 1, and said pad being encased within a flat, cloth-like envelope having attached straps for fastening the pad upon the body of a wearer of the armor; and including a pocket formed within the envelope and opening at one edge thereof, the pocket being arranged withIn the pad, between the sheets thereof, and a metal insert plate, arranged within and being removable from said pocket, so that the plate is arranged between the sheets forming the pad and may be removed and replaced as desired.
Claim 5
Dependent Claim
52 words
A construction as defined in claim 1, and comprising: said pad being encased within a flat, clothlike envelope; and a pocket formed within the envelope and opening at one edge thereof, the pocket being arranged within the pad, between the sheets thereof, and a metal insert plate removably arranged within said pocket.
