摘要： Disclosed is a stabilized substrate composition for smoking articles, particularly cigarettes. In general, the stabilized substrate composition comprises an admixture of a binder and an aerosol forming material which plasticizes the binder, together with optional fillers and/or base materials. In the stabilized substrate compositions of the present invention the relative amounts of binder and aerosol former depend particularly on the situation in which the substrate composition is used. In general, the ratio of aerosol former to binder is between about 3:1 and about 40:1. When the stabilized composition is used on a base material such as tobacco cut filler, the ratio of aerosol former to binder should be at least about 15:1, and preferably is from about 25-35:1, with a maximum ratio of about 40:1. If the composition is formed into a cast sheet, the minimum ratio is about 3:1, the preferred ratio is about 8:1, and the maximum ratio is about 10:1. When the stabilized mixture is printed on a sheet or web substrate, the ratio of aerosol former to binder is generally about 6:1, the maximum ratio is about 10:1, and the minimum ratio is about 3:1.

摘要： It has been found that the addition of specific levels of sodium, advantageously in the form of sodium carbonate, to low sodium level binder, e.g., ammonium alginate, containing carbonaceous fuel compositions results in dramatic changes in the performance of both the fuel element themselves and, cigarettes (or other smoking articles) incorporating the fuel elements. These performance differences include variation in the yields of aerosol and/or flavorants. The addition of sodium carbonate to the fuel elements greatly improves the smolder rates and also improves puff calories, without overheating the cigarette, thereby resulting in substantial improvements in total (and puff by puff) aerosol yield.

摘要： The present invention is directed to cigarettes and other smoking articles which contain a catalytic composition, preferably as part of the fuel element, that substantially decreases the amount of carbon monoxide contained in the mainstream smoke during smoking. The present invention also relates to the catalyst-containing carbonaceous fuels themselves, as well as to methods of making such carbonaceous fuels. Fuel elements which contain a catalytic composition in accordance with the presentation are especially useful in smoking articles having an aerosol generating means which is physically separate from the fuel element.

摘要： This invention features an improved spinning process for pitch-based carbon fibers, that will provide a continuous pitch-based carbon fiber having a uniform pattern of graphite crystallites over a substantial portion of the fiber cross-section and/or aligned along the fiber axis in the form of undulating ribbons. Continuous carbon fibers having the preferred orientation of graphite crystallites will exhibit greater mechanical properties.
