  • Method and apparatus for using, cleaning, and maintaining electrical heat sources and lighters useful in smoking systems and other apparatuses
    Patent number: 5878752
    Abstract: Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.

  • Smoking compositions containing an .alpha.-alkylcinnamaldehyde-release additive
    Patent number: 5301693
    Abstract: This invention provides smoking compositions which contain a novel .beta.-hydroxycarboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases .alpha.-hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

  • Smoking compositions containing a tartrate salt flavorant-release additive
    Patent number: 5199450
    Abstract: This invention provides smoking compositions which contain a novel tartrate salt flavorant-release additive, such as an acetal derivative corresponding to the formula: ##STR1## Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive as illustrated above pyrolyzes and releases benzaldehyde flavorant as a volatile component of the cigarette smoke.
