A safety fuze for use in military and commercial applications, includes a fuze body that is attached to a trigger mechanism, an energetic train contained within the fuze body, and a non-energetic fuze delay mixture that is formed in a rod form so that it can dropped inside the fuze body, without modification to the other components of the safety fuze. Preferably, the non-energetic fuze delay mixture is made of foamed celluloid.

Foamed celluloid delay fuze

The present invention relates in general to a pressure discharge mechanism for closed vessels having an internal chamber designed to hold volatile and/or explosive substances in a sealed manner comprised of an at least one eutectic composition and a threaded joint designed to open or vent the closed vessel when the contents of the closed vessel reaches a predetermined temperature while maintaining full structural integrity during normal operation. In one aspect, the closed vessel is a munitions casing which functions as intended under normal operating environments, but then when exposed to extreme temperatures, reduces the munition's high order explosion capability, and is transformed into a safe, low order reaction with significantly less reactive potential. In one aspect, the closed vessel is a transport tanker which should not release substances contained therein. However, if the tanker catches fire, the pressure relief mechanism of the present invention reduces risk of explosion.

A safety valve is provided for metallic ammunition cans having lids which form an environmental seals when closed, the safety valve automatically vents cook-off gases generated when ammunition or other energetic in the ammunition can reach elevated temperatures. The safety valve is deployed in a hole formed in a wall of the ammunition can. The safety valve employs a vent cover which is soldered by means of a eutectic material either directly to an outer surface of the ammunition can or to an insert extending through the hole in the wall of the ammunition can. The vent cover seals gases in the ammunition can until elevated temperatures cause eutectic solder to melt thus freeing a vent cover and releasing cook-off gases from inside of the ammunition can.
