Portable metal cutting pyrotechnic torch

Abstract

A portable metal-cutting pyrotechnic torch comprising a solid thermite fuel for pyrotechnics, an igniter and a thermally non-conducting handle. Further provided is a tubular body which preferably burns away with the composition.

What is claimed is:  
     
         1 . A portable metal-cutting pyrotechnic torch comprising: (a) a solid thermite fuel for pyrotechnics; (b) an igniter; and (c) a thermally non-conducting handle connected to the solid thermite fuel.  
     
     
         2 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the handle is connected to the tubular body; and (c) the igniter comprises a solid inflammable material and a strike head.  
     
     
         3 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises a strongly reducible metal oxide, Cu 2 O, and a strong reducing agent; and (c) the handle is connected to the tubular body.  
     
     
         4 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO, Cu 2 O, and Al; and (c) the handle is connected to the tubular body.  
     
     
         5 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO provided in an amount in the range of about 35-55% by weight, Cu 2 O provided in an amount in the range of about 20-55% by weight, and Al provided in the range of about 5-20% by weight; and (c) the handle is connected to the tubular body.  
     
     
         6 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO, Cu 2 O, NaClO 3  and Al; and (c) the handle is connected to the tubular body.  
     
     
         7 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO, Cu 2 O, NaClO 3  Al, and a binder; and (c) the handle is connected to the tubular body.  
     
     
         8 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO provided in an amount in the range of about 35-55% by weight, Cu 2 O provided in the range of about 20-55% by weight, NaClO 3  provided in the range of about 0-20% by weight, Al provided in the range of about 5-20% by weight, and a binder provided in the range of about 0-2% by weight; and (c) the handle is connected to the tubular body.  
     
     
         9 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises a strongly reducible metal oxide, Cu 2 O, a strong reducing agent, and a supplemental strong oxidizing agent; and (c) the handle is connected to the tubular body.  
     
     
         10 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises a strongly reducible metal oxide, Cu 2 O, a strong reducing agent, a supplemental strong oxidizing agent and a binder; and(c) the handle is connected to the tubular body.  
     
     
         11 . The torch of  claim 1 , wherein: (a) the solid thermite fuel is contained in a tubular body; (b) the thermite fuel comprises CuO provided in an amount of about 46% by weight, Cu 2 O provided in the range of about 31% by weight, NaClO 3  provided in the amount of about 12% by weight, Al provided in the amount of about 11% by weight, and a binder provided in the amount of about 1% by weight; and (c) the handle is connected to the tubular body.
