Abstract: Linear ignition fuse having an elongated core of non-detonating ignitive material, a longitudinally extending gas channel adjacent to the core for supporting an ignitive reaction which travels along the fuse, a frangible sheath of inorganic material surrounding the core and the channel, and a jacket of braided filaments encasing the sheath.

Abstract: The invention comprises a tube-tire patch, and a method and apparatus for applying said patch. The patch comprises a cured rubber member with a concave surface internally reinforced with a fabric and having a stem integral with said member and upraised generally centrally from said concave surface. The patch includes an uncured rubber layer covering the concave surface and a removable protective cover generally coextensive with the concave surface and fully covering the uncured rubber layer. The patch is especially useful for patching a punctured tube-tire. A tube-tire patch as described above is inserted through the puncture after appropriate buffing and cleaning about the puncture with the stem portion of the patch extending through the puncture. The protective cover is removed from the concave surface through the puncture and thereafter a pulling force is exerted upon the stem and away from the puncture.
