Abstract
Abstract A magazine for caseless propellant charges which are entirely consumed leaving no residue after burning, for use in both military and commercial applications, including an extended flexible band having a plurality of recesses, each adapted for receiving a single propellant charge, spaced along the length of said band. Additionally, the band may incorporate a plurality of depressions, apertures and/or projections spaced along the length thereof for indexing of the magazine relative to the activating device. Further, a readily detachable foil may be secured adhesively along one or both major surfaces of the band to retain the propellant charges with the respective recesses and simultaneously shield them from heat which could cause accidental detonation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A magazine for caseless propellant charges, which burn completely leaving no residue, comprising a relatively flexible, coilable band having a width substantially greater than its thickness and a constant cross section over the entire length thereof so as to have a uniform thickness and width at all points, said band being provided with a plurality of recesses therein spaced at intervals along the length thereof, a propellant charge in each of said recesses being axially disposed at right angles to the plane of the band for receiving said propellant charge, the thickness of the band corresponding at least to the length of the propellant charge disposed therein.
Claim 2
Dependent Claim
107 words
A magazine for caseless propellant charges, which burn completely leaving no residue, comprising a relatively flexible, coilable band having a width substantially greater than its thickness and a constant cross section over the entire length thereof so as to have a uniform thickness and width at all points, said band being provided with a plurality of recesses therein spaced at intervals along the length thereof, a propellant charge in each of said recesses being axially disposed at right angles to the plane of the band for receiving said propellant charge, the thickness of the band corresponding at least to the length of the propellant charge disposed therein.
Claim 3
Dependent Claim
21 words
A magazine according to claim 1, wherein said band means is further provided with indexing means spaced along the length thereof.
Claim 4
Dependent Claim
18 words
A magazine according to claim 2, wherein said band means is formed from a thermoplastic synthetic resin material.
Claim 5
Dependent Claim
16 words
