Abstract From the Canadian patent
Liquid monopropellants for passive vehicle restraint systems (e.g. air bags) include an aqueous solution of a water-soluble oxidizer and a water-soluble organic fuel miscible with the oxidizer. The oxidizer is most preferably ammonium nitrate, hydrogen peroxide or nitric acid while the fuel is a lower , alcohol such as methanol ethanol, propanol or glycerol. The liquid monopropellants will advantageously have an oxidation ratio (O~R?) of greater than about 0.90.

Why it's free to use
- Filed December 20, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 20, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
