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.

Abstract: A method and apparatus are provided for preparing discrete blanks from a wound strip comprising a plurality of connected blanks. Each blank has a determined separation point and a marker at a determined distance from the determined separation point for making soft-type wrappers. First, the wound strip is unwound under tension. Next, at least a section of a particular blank of the unwound strip is cut and any other milling and preparatory steps are performed by appropriate rollers and mechanisms. The tension of the unwound strip is slackened periodically, e.g., via chocking these rollers, and the unwound strip is realigned relative to the marker of the particular blank during this slackening, e.g, by identifying the marker via a sensor and driving the strip via rollers. The particular blank of the realigned strip is separated at the determined separation point of the particular blank to separate the particular blank from the realigned strip.

Abstract: A smoking article is provided in which a replaceable tobacco flavor unit containing tobacco flavor material is electrically heated by a set of permanent reusable heaters to evolve flavors or other components in vapor or aerosol form for delivery to a smoker.

Abstract: A process for expanding tobacco is provided which employs carbon dioxide gas. Tobacco temperature and OV content are adjusted prior to contacting the tobacco with carbon dioxide gas. The disclosed process is suitable for impregnating and expanding tobacco having a high bulk density. In order to achieve a high bulk density, the tobacco may be compacted or compressed to achieve an increased and more uniform bulk density prior to its impregnation with carbon dioxide. The process may be carried out with a short cycle impregnation in an apparatus according to the invention. A thermodynamic path is followed during impregnation which allows a controlled amount of the carbon dioxide gas to condense on the tobacco. This liquid carbon dioxide evaporates during depressurization helping to cool the tobacco bed uniformly. After impregnation, the tobacco may be expanded immediately or kept at or below its post-vent temperature in a dry atmosphere for subsequent expansion.

Abstract: Reconstituted tobacco sheets manufactured from tobacco dust and binder are described herein. More particularly, the tobacco dust has a mean particle size in the range of from about 60 mesh to about 400 mesh to afford reconstituted tobacco sheets having about 80% to about 90% tobacco content with improved quality and survivability. The reduced particle size of the tobacco dust allows an increase in the solids content of the slurry without an increase in slurry viscosity. The increased solids content reduces the drying load of the cast sheet thereby allowing an increased production rate. The reconstituted tobacco sheets may be prepared from a slurry comprising tobacco dust and binder that may be subjected to a means for removing air trapped within the slurry before casting the slurry into sheets. An apparatus for determining the amount of air trapped within the slurry prepared according to the process of the present invention is also described herein.
