Abstract: A cigarette, having a tobacco rod consisting of at least two segments. The segment toward the filter end of the tobacco rod has a density at least 20% greater than the fire-end segment. The density differential may be combined with a nicotine differential, such that the fire-end segment has a higher nicotine content than does the filter-end segment. This configuration alters the nicotine delivery of the invention, providing a nicotine delivery either uniform during the last half of the cigarette or at levels reduced from those seen during the first few puffs.

Abstract: A non-volatile source of ketone to flavor tobacco smoke is provided by a .beta.-ketocarboxylic acid ester of a sugar or related compound. The ester is applied to the smoking material and remains in place until the burning coal releases the ketone.
Abstract: A blend of dark-fired and one-sucker tobacco and a cased cigar type tobacco are cut to obtain a shredded product. After the addition of water and a binder, the resultant mixture is heated, dried and then pelletized into individual discrete pellets. Various additives can be added prior to or during pelletizing. The pellets are sized to give the user the desired taste and flavor of a conventional smokeless tobacco.

Abstract: A substantially cylindrical foamed, extruded, tobacco-containing smoking article is provided which has properties substantially equivalent to those of a conventional cigarette and which contains from about 5 to about 98 wt. % of tobacco particles having a particle size of up to about 5 mesh, from 0 to about 60 wt. % of a filler having a particle size of up to about 350 .mu.m mesh, from about 2 to about 40 wt. % of a cellulosic binder selected from the group consisting of hydroxypropyl cellulose, carboxymethyl cellulose, and its sodium, potassium and ammonium salts, cross-linked carboxymethyl cellulose, and its sodium, potassium and ammonium salts, hydroxyethyl cellulose, ethyl hydroxyethyl cellulose, hydroxypropyl methyl cellulose, methyl cellulose, ethyl cellulose, and mixtures thereof, and from about 5 to about 20 wt. % water. The article has a density within the range of from about 0.05 to about 1.5 g/cc.
Abstract: The invention concerns a method for modifying the peripheral conformation of a cigarette, which has an external, heat deformable, wrapper comprising a proportion of thermoplastic fibers or filaments. The method comprises the application of heat to the wrapper. Heat is applied by a heat forming means moved relatively and in contact with the cigarette, in a direction transverse to the longitudinal axis of the cigarette.

Abstract: Smoking articles comprising a high density, relatively low porosity coherent mass of combustible tobacco-containing material having at least one passage extending therethrough are disclosed. In a preferred embodiment the smoking article is a cylinder having at least one passage axially therethrough. The smoking article may further comprise a plug of ignitable material in passage blocking position at one end of the passage, said plug being such as to permit puff induced air flow therethrough. At least one additional plug may be similarly disposed at the opposite end of the passage or at an intermediate point in the passage. By adjusting the density, the surface area and/or the porosity of the mass available for combustion, the per puff delivery of tar by the smoking article upon combustion may be controlled.
