    • A gas generator composition reduced in the concentration of harmful gases, particularly carbon monoxide and nitrogen oxides, in the gas generated therefrom to such a level as to put the composition to practical use as an automotive air bag system. The composition comprises a nitrogenous organic compound such as an organic compound having an amino or amido group or a tetrazole derivative and an oxygenous inorganic oxidizing agent such as KNO3, Sr(NO3)2 or KC1O4 as the essential components and contains manganese dioxide having a specific surface area of 50 m /g or above, copper oxide having a specific surface area of 1 m /g or above, a molybdenum oxide catalyst comprising at least one member selected from the group consisting of molybdenum dioxide, molybdenum trioxide, molybdic acid and ammonium molybdate, or a mixed catalyst comprising manganese dioxide and one or more metal oxides selected from the group consisting of copper oxides, cobalt oxides, iron oxides and silver oxides.

    • This invention pertains to an article that emits infrared radiating for a period of about 15 minutes or more, depending on the size and shape, and to a process for preparing the article. The article includes, in a preferred embodiment, a combustible aerogel or other nanocellular substrate with iron metal impregnant formed by thermal decomposition of iron pentacarbonyl deposited on and in the substrate in an amount of at least about 5 % or at least about 20 % of the weight of the substrate, depending on the substrate. The impregnant reacts exothermically on contact with air or an oxygen-containing gas and imparts sufficient energy to the substrate to cause it to burn for about 30 seconds to about 30 minutes depending on size and shape, thereby emitting infrared radiation. The process pertains to deposition of the impregnant on and in the substrate by flowing a carrier gas saturated with the impregnant precursor over and through the substrate. Liquid impregnant precursors can be transported to the substrate by bubbling a carrier gas through the precursor. Solid impregnant precursors can be thermally volatilized and similarly deposited on and in the substrate. Soluble impregnants, or their precursors, can be deposited on the internal and external surfaces of the substrate by diffusing the precursor solution into the pores and distilling off the solvent under inert atmosphere, leaving the pyrophoric impregnant in and on the substrate surfaces.
    • 本发明涉及根据尺寸和形状发射约15分钟或更长时间的红外辐射的制品以及制备该制品的方法。 在优选实施方案中,该制品包括具有铁金属浸渍剂的可燃气凝胶或其它纳米细胞基质,所述浸渍剂以沉积在基材上和底物中的铁五羰基铁的热分解形成,其量为至少约5%或至少约20% 取决于衬底的重量。 浸渍剂在与空气或含氧气体接触时放热反应,并向基材赋予足够的能量以使其燃烧约30秒至约30分钟,这取决于尺寸和形状,从而发射红外辐射。 该方法涉及通过使浸渍剂前体饱和的载气流过衬底并在衬底上沉积浸渍剂而沉积在衬底中。 液体浸渍剂前体可以通过使载气鼓泡通过前体而被输送到基底。 固体浸渍剂前体可以被热挥发并且类似地沉积在基材上和底物中。 通过将前体溶液扩散到孔中并在惰性气氛下蒸除溶剂,可溶性浸渍剂或其前体可沉积在基材的内表面和外表面上,将自燃浸渍剂留在基材表面上和基材表面上。
