Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A rotating rod warhead for rapidly erecting an expanding screen of pellets in a uniform pattern, comprising: (a) two similar housing units connected together to form a substantially cylindrical shaped housing assembly, (b) a plurality of rod-shaped pellets retained within said cylindrical housing assembly for dispersing the pellets in a uniform pattern upon release thereof, said two housing units each having a circumferential retaining means thereabout for effectively retaining said pellets in a bundle within said housing parallel to each other and to the spin axis, (c) pellets positioned about the outer circumference of said bundle of pellets being longer than the others and in the form of rocker type restraint beams which hold the other pellets in restraint at a point midway between the ends thereof to equalize any differential forces tending to perturb the pellets during spin-up and at release, the ends of the restraint beams having their ends held by said circumferential retaining means, (d) drive means for spinning said housing assembly about its cylinder axis at a desired rotational speed for suitably dispersing said pellets upon their release, (e) actuator means for quickly separating said two housing units and releasing said pellets.
Claim 2
Dependent Claim

A rotating rod warhead for rapidly erecting an expanding screen of pellets in a uniform pattern, comprising: (a) two similar housing units connected together to form a substantially cylindrical shaped housing assembly, (b) a plurality of rod-shaped pellets retained within said cylindrical housing assembly for dispersing the pellets in a uniform pattern upon release thereof, said two housing units each having a circumferential retaining means thereabout for effectively retaining said pellets in a bundle within said housing parallel to each other and to the spin axis, (c) pellets positioned about the outer circumference of said bundle of pellets being longer than the others and in the form of rocker type restraint beams which hold the other pellets in restraint at a point midway between the ends thereof to equalize any differential forces tending to perturb the pellets during spin-up and at release, the ends of the restraint beams having their ends held by said circumferential retaining means, (d) drive means for spinning said housing assembly about its cylinder axis at a desired rotational speed for suitably dispersing said pellets upon their release, (e) actuator means for quickly separating said two housing units and releasing said pellets.
Claim 3
Dependent Claim
52 words
A device as in claim 1 wherein said pellets are retained within said housing parallel to each other and to the spin axis of the housing, and upon release therefrom will remain substantially oriented with their longitudinal axes parallel to said spin axis while dispersing to form an expanding screen of pellets.
Claim 4
Dependent Claim
24 words
A device as in claim 1 wherein said cylindrical housing forms an annular container for retaining said pellets in an annular bundle until released.
Claim 5
Dependent Claim
18 words
A device as in claim 1 wherein said rod-shaped pellets are in the form of hollow slender rods.
Claim 6
Dependent Claim
26 words
A device as in claim 1 wherein said actuator means comprises a detonator device for quickly separating said housing units on signal to release said pellets.
Claim 7
Dependent Claim
42 words
A device as in claim 5 wherein said detonator device is located in an area where upon actuation there will be an absence of any explosion around the cylindrical periphery of said housing units that could perturb said pellets on their release.
Claim 8
Dependent Claim
45 words
A device as in claim 1 wherein said housing units and pellets are supported on a spool means which permits unrestrained equal and opposite motion of the two housing units upon actuation of said actuator means for release of the pellets in a uniform pattern.
