An incendiary cutting torch comprising: A. a cylindrical housing having an elongate cylindrical bore formed the length thereof defining a fuel receiving chamber and having an open end and a closed end; B. a nozzle detachably connected to said open end of said housing and having at least one aperture
An incendiary cutting torch comprising: A. a cylindrical housing having an elongate cylindrical bore formed the length thereof defining a fuel receiving chamber and having an open end and a closed end; B. a nozzle detachably connected to said open end of said housing and having at least one aperture their in; C. a retaining member connected to said open end of said housing having means to receive said nozzle and hold it in position and a bottom portion integral therewith effectively closing said open end; D. a diaphragm integral within said retaining member adapted to withstand a predetermined internal pressure within said fuel receiving chamber; E. a first fuel component in the form of a stack of cylindrical pellets each having a bore hole in its center and aligned such that an elongated bore hole runs through the center of the pellet stack for its entire length, said stack leaving a space in the fuel receiving chamber at the closed end away from the nozzle, wherein said first fuel component pellets are pressed from an intimate powder mixture of (1) nickel, (2) metal oxide, (3) a component selected from the group consisting of (a) aluminum and (b) a mixture of at least 50 weight percent aluminum and a metal selected from the group consisting of magnesium, zirconium, bismuth, beryllium, boron, and mixtures thereof, and (4) solid material which will decompose to form a gas when exposed to the heat of the reacting fuels; F. a second fuel component in the form of a loose powder which fills the bore hole in the stack of first fuel component pellets and fills the space left between the stack and the closed end of the fuel receiving chamber, wherein the second fuel component is (1) Mg powder, (2) an intimate mixture of Mg and CuO powders, (3) an intimate mixture of Mg and Fe2O3 powders, (4) an intimate mixture of Mg and Co3O4 powders, (5) an intimate mixture of Al and CuO powders, (6) an intimate mixture of Al and Fe2O3 powders, (7) mixtures thereof, wherein from about 0.80 to about 1.25 times the stoichiometric amount of Mg is used for mixtures (2), (3), and (4), and wherein from about 0.80 to about 1.25 times the stoichiometric amount of Al is used for mixtures (5) and (6); and G. means by which a standard military incendiary grenade fuse may be inserted into the closed end of the reaction chamber such that the grenade fuse is positioned to ignite the second fuel component powder filling the space at the closed end of the fuel receiving chamber.
