First Claim
Patent Images
1. A thermite igniter/heat source comprising:
- a housing being comprised of a thermally insulative material capable of withstanding relatively high temperatures, said housing comprising a first portion having a bottom exit port, a relatively open top forming a center thermite receiving area, and having a relatively low profile with a relatively small height relative to its width, said housing further comprising a second portion forming a top for said thermite receiving area, said housing having means for passing a fuse into said center thermite receiving area;
high-density thermite located in said thermite receiving area; and
low-density thermite located in said thermite receiving area between an outer top member and said high-density thermite such that a fuse passing into said passing means can ignite said low-density thermite which in turn can ignite said high-density thermite and can exit heat from said exit port with a torch-like ejection of hot reaction products.
