Abstract
An autoignition system for use in an inflator or method of inflating includes a separator which divides a composition capable of spontaneous combustion or autoignition so that it cannot combust until the separator is removed or altered in form. The separator is made of a material which melts at a select temperature so that autoignition will occur upon melting of the separator. The system can also use the separator or a burst disc to sensitize a desensitized spontaneous combustion mixture to achieve autoignition at a desired temperature.
Claims34
A system producing an autoignition at a select temperature comprising:
- (a) a composition having at least one first component and at least one second component which when combined together autoignite;
- and
- (b) a separator interposed between the at least one first component and the at least one second component, the separator having a melting point generally corresponding to the autoignition select temperature, so that when the system is subjected to the autoignition select temperature, the separator melts and the at least one first and the at least second components are combined for the autoignition, wherein the melting point of the separator ranges between about 60.5.degree. C. and 199.degree. C.
A system producing an autoignition at a select temperature comprising:
- (a) a composition having at least one first component and at least one second component which when combined together autoignite;
- and
- (b) a separator interposed between the at least one first component and the at least one second component, the separator having a melting point generally corresponding to the autoignition select temperature, so that when the system is subjected to the autoignition select temperature, the separator melts and the at least one first and the at least second components are combined for the autoignition, the separator being made of an eutectic metal alloy.
