Abstract: The present invention relates to a smoking article which produces an aerosol that resembles tobacco smoke, but contains no more than a minimal amount of incomplete combustion or pyrolysis products.Preferred embodiments of the present smoking article comprise a short combustible carbonaceous fuel element, a heat stable substrate bearing an aerosol forming substance, a heat conducting member which contacts a portion of the fuel element and the substrate, and an insulating jacket surrounding at least a portion of the fuel element.The smoking article of the present invention is capable of providing an aerosol "smoke" which is chemically simple, consisting essentially of air, oxides of carbon, water, and the aerosol which carries any desired flavorants or other desired volatile materials, and trace amount of other materials. The aerosol "smoke" from the preferred embodiments has no significant mutagenic activity as measured by the Ames Test.

Abstract: In one aspect, the invention provides a simple, readily manufacturable, low tar cigarette with individual puff deliveries similar to those obtained from conventional cigarettes which have a higher total smoke delivery such as a full flavor cigarette. The low tar cigarette includes a tobacco rod segment having a length of 53 mm. or less abutting a filter segment having an overall length of at least 31 mm. wherein the filter segment includes a synthetic fiber filter plug and provides a smoke delivery reduction of at least 55% and wherein the cigarette has an average puff count of 6.5 or less. In another aspect, the invention provides nonconventional smoking articles which have an elongated nonsmokable mouthend portion, i.e.

Abstract: A method and system for effecting sensory evaluation of a smoking product wherein selected smoking parameters are monitored precisely while a smoking product is being smoked ad libitum by a sensory evaluation panelist. The monitored smoking parameters are used to coordinate a sequence of instructions and prompts that is communicated to the sensory evaluation panelist and is designed to elicit sensory ratings from the panelist for the product being smoked. This allows the smoking product to be evaluated with the least possible disruption to the panelist's normal smoking patterns and leads to a better understanding of the smoking characteristics of the product being evaluated.

Abstract: Filter cigarettes can be manufactured in a highly cost effective manner. Filter cigarettes include a tobacco rod having two segments of smokable material. The first segment is positioned at the lighting end of the cigarette and includes expensive, normally high quality tobaccos. The second segment is positioned at the filter end of the rod and includes cost effective smokable materials. A cellulose acetate filter element is axially aligned with the rod and is positioned adjacent to the second segment. Tipping material attaches the filter element to the tobacco rod. The second segment extends along the rod up to about 20 mm past the foremost point which the tipping material extends. The combined longitudinal length of the filter element and the second segment extends up to about 60 percent of the total length of the smoking article.

Abstract: Filter cigarettes exhibiting a low amount of visible staining have a tobacco rod, an axially aligned filter element having a barrier region positioned on the back face thereof such that air and smoke traveling through the filter element exits the filter element towards the periphery thereof, and an axially aligned tubular mouthpiece element positioned in a spaced apart relationship with the filter element such that air and smoke exiting the filter element travels through the path of least resistance provided by the spaced apart region and the hollow region of the tube.

Abstract: A smoking article such as a filter cigarette can have an adjustable delivery air dilution while exhibiting a reduced pressure drop decrease during air dilution thereof. The pressure drop decrease is controlled during various stages of air dilution by providing a mouthpiece which exhibits greater effective length at a low or non-air dilution setting than at a high air dilution setting. Filter cigarettes of this invention are capable of exhibiting a somewhat constant smoking character at various air dilution levels.

Abstract: A smoking article such as a filter cigarette can have an adjustable delivery air dilution while exhibiting a reduced pressure drop decrease during air dilution thereof. The pressure drop decrease is controlled during various stages of air dilution by positioning the structure for greatest air dilution on the cigarette a greater distance from the extreme mouthend of the cigarette relative to the structure for least air dilution. Filter cigarettes of this invention are capable of exhibiting a somewhat constant smoking character at various air dilution levels.
