Claims11
A gas-forming pyrotechnic fuel composition load for use in apparatus for severing conduits in high pressure environments comprising a plurality of stacked fuel pellets of a mixture of (a) a metal selected from the group consisting of aluminum, magnesium, niobium, titanium and mixtures thereof, (b) a metal oxide selected from the group consisting of ferric oxide, ferrous oxide, ferrosoferric oxide, cupric oxide, chromium trioxide and mixtures thereof, and (c) a gas-forming component which vaporizes to form a gas when heated to the temperature at which said metal and said metal oxide react when ignited wherein alternate fuel pellets of said load have alternate amounts of said gas-forming component.
