Abstract: A caseless formed propellant powder charge including a shaped propellant powder charge having a central continuous recess or hole and a percussion-sensitive primer charge with an H-shaped cross section disposed in the recess. Preferably, the shaped propellant charge and the primer charge are fabricated from materials such as nitrocellulose, polyvinyl nitrate, nitroguanidine, penthrite, or mixtures thereof, and tetrazene or tetrazene tricinate, respectively. The compression and dimensioning of the various portions of the H-shaped primer charge may be modified to achieve the desired sensitivity.

Abstract: Heating and temperature maintenance device including a hollow body portion containing a core housing, a material to be heated, a first chamber disposed about the core containing a first pyrotechnic composition capable, upon ignition, of rapidly heating the material to a desired temperature, a meltable metal or alloy disposed about the first chamber capable of being melted by the ignition of the first pyrotechnic composition, and a second chamber, disposed between the body periphery and the metal or alloy, containing a second pyrotechnic composition having, upon ignition, a slower burning rate than the first pyrotechnic composition and capable of maintaining the metal or alloy in a molten condition for a predetermined time.
