Abstract: What is presented is a metal magnalium thermite pellet that is used to create heated gas. The metal magnalium thermite pellet is made to be inserted into the cutting apparatus that is used for cutting a conduit for oil, gas, mining, and underwater pressure sealed tool applications. To cut the conduit, the cutting apparatus radially projects a flow of heated gas from the internal surface of the conduit through to its external surface. The metal magnalium thermite pellet is also made to be inserted into the high power igniter that releasably secures to the cutting apparatus. Generally, the metal magnalium thermite pellet comprises a metal magnalium thermite composition that consists of between 1 to 44 percent magnalium alloy, 1 to 44 percent aluminum, 40 to 60 percent iron oxide, and 10 to 20 percent polytetrafluoroethylene.

Abstract: A kinetic energy penetrator for use in small caliber ammunition, which penetrator can utilize composite material small sabots. A large shear area in the sabot having a small number of decreasingly sized buttress grooves, mate to the penetrator shaft making use of composite material sabots feasible. Lightening of the penetrator through substitution of composite material sabots results in greater velocity with higher kinetic energy on lethal impact. The fewer grooves aerodynamically lessen drag and likewise tend to boost velocity plus lethal impact.
