Abstract: A testing tank for securing and enclosing a plurality of gas discharge ports of a hybrid inflator during test firing of the inflator, the testing tank having a tank container, a lid and an adaptor system. The tank container has an open top communicating with an enclosed test chamber while the lid covers the opening in the tank container and has an aperture communicating with the test chamber through the opening. The adaptor system has an adaptor ring secured to the testing tank surrounding the opening, and an inflator housing having a sleeve-like body fitting within the adaptor ring. The inflator housing is snugly positionable around a hybrid inflator so that the cylindrical sidewall of the hybrid inflator will extend into the test chamber of the testing tank with the gas discharge ports located therein. Sealing means and securing means secure the gas discharge ports of the hybrid inflator within the test chamber in a gas-tight manner.

Abstract: Apparatus for x-ray viewing of the firing cycle of an air bag inflator includes a pressure tank for containing an inflator during a firing cycle thereof having an access opening in a wall for receiving the inflator. A mounting ring is secured in place in the access opening having a stop flange at an inner open end for engaging the base of the inflator when inserted into the open end of the housing and limiting the amount of insertion of the inflator into the tank. A pressure plug is removably securable in the mounting ring to engage the base of the inflator for rigidly securing the same in a fixed position in the tank and sealing off the tank during a firing cycle. An x-ray apparatus and film pack or recorder are disposed on opposite sides of the tank to view the progress of the ignition process during a firing cycle of the inflator.
