ABSTRACT:
An ignitable charge for producing pressurized gas to power industrial tools; that is made of plentiful, common materials at a very low cost, lower in cost than conventional charges by orders of magnitude. The charge is comprised of a hollow plastic jacket of triangular cross section that is open through its center to both opposite ends and contains a nitrocellulose propellant in uncompressed, or expanded form that may be electrically ignited through one end of the jacket by a spark, hot wire, or the like in an open chambertype feed and firing mechanism. The charge produces pressurized gas at the desired burning rate and peak pressures for operating the tool.
