Patent ID: 7695007

Claim:
A device for deploying an element comprising: a first chamber enclosing at least one primary pyrotechnic compound having a characteristic of a ballistic propellant; a passageway connected to and extending from the first chamber; at least one initiator equipped with a reinforcing charge to initiate decomposition of the primary pyrotechnic compound(s); a second chamber enclosing a secondary compound having a decomposition rate less than the decomposition rate of the primary pyrotechnic compound(s), the secondary compound that decomposes in response to decomposition of the primary compound that receives gases generated as a result of a decomposition of the primary pyrotechnic compound(s) as said gases emanate from the first chamber; and a weakly confined reaction chamber having a vent opening and positioned between the passageway and the second chamber and in communication with the first and second chambers such that the weakly confined reaction chamber receives combustion products generated as a result of decomposition of the primary pyrotechnic compound(s) and oxidizing gaseous entities generated as a result of decomposition of the secondary compound for at least one post-combustion oxidoreduction reaction between the combustion products and the oxidizing gaseous entities and vents gases generated by the post-combustion oxidoreaction to the element through the vent.
