The dynamics of accounting change: inter-play between new practices

This invention relates to a method of obtaining the release of a large amount of epurated gas at a moderate temperature in an extremely short time whereby, for example, a safety cushion or bag for automobile vehicles may be very quickly filled, e.g. to protect passengers in the event of a collision. A solid propellant is burned and the gases resulting from its combustion is placed in contact with a vaporisable cooling liquid. This liquid is an oxidizing compound so as simultaneously to cause epuration of the combustion gases by oxidation of the noxious ingredients in these gases into non-harmful products and also cooling of these gases by mixing them with the said liquid and vaporisation of the latter. The invention also provided a gas generator for carrying out this method.
