Abstract: A fire suppression system for producing an inert gas mixture having a minimal amount of carbon monoxide, particulates, or smoke. The inert gas mixture may be generated by combusting a gas generant. The gas generant may be a composition that includes hexa(ammine)-cobalt(III)-nitrate. The fire suppression system also includes a heat management system to reduce a temperature of the inert gas mixture. A method of extinguishing fires is also disclosed.

Abstract: Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite ammine, metal nitrate ammine, and metal perchlorate ammine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices, such as automobile air bags.

Abstract: A method and system for selling a software product, and for preventing theft at the point of purchase, comprises: manufacturing a product (26), preferably at a sales outlet (20); generating a unique unlock code for the product, without which the product will not operate; displaying the product for sale at the sales outlet, while storing the unlock code separately form the product; and, on purchase of the product by a customer, supplying the customer with both the product and the unlock code. Since the unlock code is not printed onto the packaging, nor is it burned to the CD or other machine-readable media, the product can safely be left out for display and purchase in store without substantial risk of theft.
