Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
156 words
Apparatus for dispensing a BW-CW agent, comprising; a. A cylindrical seamless metal canister tube having reduced wall thickness at its opposite ends, b. A commercially flat tin can lid secured to each of the reduced end portions with a conventional tin can crimp, c. A centrally disposed cylindrical burster tube extending between said lids, d. The annular space between the canister and burster tube being filled with a BW-CW agent, e. said agent being in gel form and thickened by a thickening agent to a viscosity between 10,000 and 100,000 centipoise, f. said burster tube containing an explosive propellant of a type and in a quantity that when initiated, it produces pressure within the container of low order and considerably below the pressure attendant with a high explosive shock wave, to effect rupture of the canister and dispersion of the agent in relatively large particles considerably larger than would be dispersed by an attendant shock wave.
