A lighter is provided having a tobacco flavor heating system which includes a rotatable tobacco containing disc or spiral. This disc or spiral is registered in thermal proximity to a heating element and heated to generate tobacco flavors in response to a sensor. The disc and spiral are sized to provide a convenient number of puffs before disposal. Housings are provided for the disc and spiral to store, register and dispose the tobacco product efficiently. An induction heating system can be employed.

A method and apparatus are provided for applying an adhesive solution to the coal end of a cigarette by means of a precisely controlled liquid jet spray to bond shreds of tobacco in the cigarette end and to thereby reduce the amount of tobacco which falls out of the cigarette when shaken. Electronic controls are employed to synchronize the formation and charging of a series of droplets which are deflected in prescribed paths to contact the coal end of the cigarette in a predetermined pattern. Circuits are provided to adjust the timing and phase of the charging mechanism to compensate for variations in the speed at which the cigarette is conveyed to a target area and for variations in the timing of droplet formation.

Droplet jet application of adhesive to cigarette ends

An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.

In one embodiment this invention provides a cigarette product which contains a novel type of encapsulated flavorant-release filament. The flavorant is released under normal smoking conditions.

Process for making a flavorant-release filament

Filamentary flavorant-release additive for smoking compositions

This invention provides a dispensing assembly which is adapted to deliver two separate instantaneously coreactive liquid streams into an external contacting zone. The two reactants do not make contact within the body of the dispensing assembly, which prevents solid product formation and clogging within the dispensing assembly nozzles. The dispensing assembly is suitable for the coreaction of liquid carbon dioxide and liquid ammonia to produce free-flowing ammonium carbamate powder having a purity of substantially 100 percent.

Ammonium carbamate production

In the course of continuous transport of filamentary material, mutually spaced portions thereof are selectively stretched, yielding articles having a longitudinal profile varying in filamentary material volume and of essentially constant filament density per unit volume. In producing cigarette filters, additive material is applied to the stretched material portions.

Method and apparatus for making cigarette filters of filamentary material

A practice for measuring porosity wherein a plurality of medium flows of different volumetric flow rates are provided to a predetermined area of a material under test in dependence upon the pressure difference thereacross and wherein certain measured pressure /differences and their corresponding flow rates are employed to determine the material porosity.

Method and apparatus for measuring porosity

Material is collected in radially extending slots opening into the outer periphery of a first wheel intermittently rotated about a first axis to successively dispose material-containing slots at a registration location. A second wheel is rotated synchronously with the first wheel about an axis perpendicular to the first axis to successively dispose slots extending axially therein at the registration location. Material is forcibly discharged from the first wheel slots to the second wheel slots as they are maintained in stationary facing relation at the registration location.
