Abstract
Abstract A weapon for firing a ballistic disc at an explosive ordnance device for disabling the target device. The ballistic disc, which is spherically curved and being of greater thickness at its central portion than at its peripheral portion, is positioned transversely within a cartridge casing with its concave side toward the target. A planar shock front is generated by an explosive train in the cartridge to propel the disc toward the target at very high velocities and, during initial flight, the concave disc configuration inverts to a convex streamlined teardrop shape.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
An ordnance disabling weapon comprising: an elongate casing having a cylindrical bore extending longitudinally therethrough, a spherically curved ballistic disc having concave and convex sides and a central portion of greater thickness than the peripheral portion, said disc yieldingly retained about its periphery within said bore at a first end of said bore with the concave side facing outwardly, main pressure generating means disposed within said bore behind said disc for generating a planar shock front to propel said disc from its yieldingly retained position, an elongate plug received and fitting the diameter of a second end of said bore and having a length less than the length of said casing, said plug having a stepped axial bore defining a small igniter chamber and a large booster chamber having a length greater than its diameter, an igniter charge received in said igniter chamber, a booster charge received in said booster chamber whereby said booster charge contacts said main pressure generating means and said initiator charge, and a platform adapted for supportingly engaging said casing when firing said ordnance disabling weapon.
Claim 2
Dependent Claim
180 words
An ordnance disabling weapon comprising: an elongate casing having a cylindrical bore extending longitudinally therethrough, a spherically curved ballistic disc having concave and convex sides and a central portion of greater thickness than the peripheral portion, said disc yieldingly retained about its periphery within said bore at a first end of said bore with the concave side facing outwardly, main pressure generating means disposed within said bore behind said disc for generating a planar shock front to propel said disc from its yieldingly retained position, an elongate plug received and fitting the diameter of a second end of said bore and having a length less than the length of said casing, said plug having a stepped axial bore defining a small igniter chamber and a large booster chamber having a length greater than its diameter, an igniter charge received in said igniter chamber, a booster charge received in said booster chamber whereby said booster charge contacts said main pressure generating means and said initiator charge, and a platform adapted for supportingly engaging said casing when firing said ordnance disabling weapon.
Claim 3
Dependent Claim
21 words
The device of claim 1 further comprising: a severable closure cap attached to said plug and hermetically sealing said igniter chamber.
Claim 4
Dependent Claim
71 words
The device of claim 1 wherein said platform comprises: a flat rectangular body of manually bendable material having a U-shaped cutout portion formed in one end thereof to define an elongate key and additionally having a plurality of longitudinal slits cut therein whereby said platform may be stored and transported in a flat knocked down configuration and bent by hand to form legs to hold said ordnance disabling weapon in use.
Claim 5
Dependent Claim
30 words
The device of claim 3 wherein said casing has a complementary keyway formed therein along a portion of the length of said casing and adapted to slidably receive said key.
Claim 6
Dependent Claim
22 words
The device of claim 3 further comprising: an optical sighting mechanism mounted on the exterior of said casing for aiming the weapon.
