  • Patent number: 5560376
    Abstract: A method of and apparatus for adjusting and controlling the moisture content of carbonaceous fuel components used in making smoking articles comprises a mass flow accumulator and a dryer through which the fuel components are conveyed. Unheated air is flowed over the fuel components in the accumulator to adjust and maintain the moisture content of the fuel components to a level which permits cutting of the fuel components without chipping or cracking. After the fuel components are cut into individual fuel elements and combined with an aerosol generator or substrate they are conveyed through the dryer where heated air is flowed over them to further reduce the moisture content to a desired level for further processing and manufacture into smoking articles.

  • Patent number: 5345955
    Abstract: The present invention is directed to improvements in carbonaceous fuel elements wherein (a) the fuel elements are provided with a composite support member which assists in retaining the fuel element within the cigarette structure during smoking, and (b) the fuel elements burn at a lower average temperature than previously known carbonaceous fuel elements. In one preferred embodiment of the present invention, the fuel element comprises at least two different materials contiguous throughout the length thereof, and including one material which burns, and another material which preferably does not burn, or burns more slowly than the burnable material. The non-burning, or substantially non-burning material is advantageously a heat exchange material such as graphite.

  • Patent number: 5247947
    Abstract: A cigarette including a longitudinally segmented combustible fuel element, and a substrate carrying tobacco extract and glycerin positioned physically separate from the fuel element is disclosed. The substrate is a gathered paper-type material, and is positioned in a spaced apart relationship from the fuel element. One preferred smoking article of the present invention is a cigarette which comprises (i) a symmetrical and longitudinally segmented combustible fuel element; (ii) a physically separate aerosol generating means including at least one aerosol forming material; and (iii) means for securing, maintaining or retaining the fuel element within the smoking article.
