Abstract
Abstract A device for safe containing mini-charge rounds and controlled dispersal ofhe rounds by tiers into a swarm of desired size and density when actuated by a fusing signal. The device utilizes chambered gas in a series of metered pressure drops to inflate diaphragms and develop controlled forces. These forces are imposed upon the mini-charge rounds to deploy the rounds from each tier by lateral force into radial patterns expanding at different rates to provide the pattern density required.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
120 words
A device for deploying multi-tiered charged rounds into radial patterns expanding at different rates therefrom, said device comprising: a sectional enclosing case; stops in said device to separate each tier of charged rounds from a succeeding tier; a gas generator associated with said case for producing gas; a tube disposed on said generator, said tube being provided with a plurality of lateral openings spaced longitudinally of said tube; a plurality of cylindrical resilient diaphragms, each diaphragm being attached to the tube at points enclosing a horizontal set of lateral tube openings and a plurality of internal restrictions in said tube that provide progressively sized horizontal orifices for developing the controlled forces to deploy said tiered rounds into radially expanding patterns.
Claim 2
Independent Claim
120 words
A device for deploying multi-tiered charged rounds into radial patterns expanding at different rates therefrom, said device comprising: a sectional enclosing case; stops in said device to separate each tier of charged rounds from a succeeding tier; a gas generator associated with said case for producing gas; a tube disposed on said generator, said tube being provided with a plurality of lateral openings spaced longitudinally of said tube; a plurality of cylindrical resilient diaphragms, each diaphragm being attached to the tube at points enclosing a horizontal set of lateral tube openings and a plurality of internal restrictions in said tube that provide progressively sized horizontal orifices for developing the controlled forces to deploy said tiered rounds into radially expanding patterns.
Claim 3
Dependent Claim
28 words
A device as set forth in claim 1 wherein said sectional enclosing case is provided with a latch for holding and releasing said case into its separate sections.
Claim 4
Dependent Claim
16 words
A device as set forth in claim 2 including a primer for igniting said gas generator.
