Abstract
Abstract The invention relates to a cartridge (1) for launching decoy material, for example chaff. The cartridge (1) contains several cassettes (11, 12, 13, 14), each cassette containing several payloads (15) with chaff or other passive and active decoys. An electronic ignition signal device (5) ensures that the payloads (15) and the cassettes (11, 12, 13, 14) may be launched in an arbitrary sequence. By means of the invention a compact cartridge is obtained which may contain a great number of payloads (10) and which has a high reliability.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A cartridge for launching decoy material, said cartridge comprising: (a) a tubular envelope having a launching end from which the decoy material is to be ejected; (b) a plurality of tubular cassettes longitudinally-arranged in the envelope, each cassette having a launching end from which decoy payloads are to be ejected; (c) a first plurality of electrically-triggered igniters, each disposed at an end of a respective one of the cassettes remote from the launching end of the envelope for effecting ejection of the cassette from the envelope; (d) a plurality of the decoy payloads, arranged transversely with respect to each other, in each cassette; (e) a second plurality of electrically-triggered igniters, each disposed at an end of a respective one of the payloads remote from the launching end of its respective cassette for effecting ejection of the payload from the cassette; and (f) an electronic signal ignition device electrically-connected to the igniters, said device including means for selectively triggering the igniters and thereby selectively ejecting the respective payload or cassette associated with any triggered igniter.
Claim 2
Dependent Claim
174 words
A cartridge for launching decoy material, said cartridge comprising: (a) a tubular envelope having a launching end from which the decoy material is to be ejected; (b) a plurality of tubular cassettes longitudinally-arranged in the envelope, each cassette having a launching end from which decoy payloads are to be ejected; (c) a first plurality of electrically-triggered igniters, each disposed at an end of a respective one of the cassettes remote from the launching end of the envelope for effecting ejection of the cassette from the envelope; (d) a plurality of the decoy payloads, arranged transversely with respect to each other, in each cassette; (e) a second plurality of electrically-triggered igniters, each disposed at an end of a respective one of the payloads remote from the launching end of its respective cassette for effecting ejection of the payload from the cassette; and (f) an electronic signal ignition device electrically-connected to the igniters, said device including means for selectively triggering the igniters and thereby selectively ejecting the respective payload or cassette associated with any triggered igniter.
Claim 3
Dependent Claim
62 words
A cartridge as in claim 1 where each of the igniters includes first and second electrical connection points for connection to the electronic signal ignition device, the first points of all igniters being electrically connected to the device by a common conductor, and the second connection point of each igniter being electrically connected to said device by a respective individual electrical conductor.
Claim 4
Dependent Claim
43 words
A cartridge as in claim 2 where the individual electrical conductors electrically connected to the igniters associated with each cassette and its associated payloads are electrically connected to respective ones of the individual electrical conductors for the other cassettes and their associated payloads.
Claim 5
Dependent Claim
50 words
A cartridge as in claim 2 or 3 where any of the electrical conductors which extend beyond the launching end of a cassette includes a frangible portion adjacent said launching end for effecting separation of the conductor when a cassette to which it is connected is ejected from the envelope.
