Abstract: A shisha device comprises a cooling element (13) disposed along an airflow channel to cool an aerosol. The cooling re) element unit utilizes active cooling and may additionally utilize passive cooling. The cooling element may comprise a conduit (21) comprising a thermally conductive material. The cooling element may be integrally formed with an accelerating element (14) disposed along the airflow channel. Cooling may occur before or during acceleration of the aerosol by the accelerating element. The cooling may contribute to the condensation in the aerosol.

Abstract: A heated aerosol-generating article is provided, including an aerosol-generating substrate including a rod, the rod including a gathered sheet of homogenised tobacco material circumscribed by a wrapper. The gathered sheet of homogenised tobacco material includes one or more plasticisers and at least about 5 percent by weight triethyl citrate on a dry weight basis. The one or more plasticisers may be selected from the group consisting of propylene glycol, sugars, and polyhydric alcohols. The sheet of homogenised tobacco material may be crimped or otherwise textured.

Abstract: An aerosol-generating system is provided, including a nicotine source; and a delivery enhancing compound source, which includes a reaction product of one or both of: (i) an alpha-keto carboxylic acid and a compound of formula (I) where R1 is selected from alkyl, phenyl, or substituted phenyl, and (ii) an alpha-hydroxy acid and a compound of formula (II) where X is a halogen and R2 is selected from H, alkyl, phenyl, or substituted phenyl.

Abstract: A rod is provided, formed from a first sheet including an aerosol-forming material and a second sheet including a non-tobacco material, the first and second sheets being gathered together and circumscribed by a wrapper. The rod may be used as a component part of an aerosol-generating article. The second sheet preferably includes a material configured to modify an aerosol evolved from the aerosol-forming material or to modify other properties of the rod.

Abstract: There is provided a machine for producing an aerosol-forming composition for an aerosol-generating system, the machine including a plurality of reservoirs configured to contain components of an aerosol-forming composition; a mixing mechanism in communication with the plurality of reservoirs; a controller connected to, and configured to control, the mixing mechanism; a user interface connected to the controller for a user to operate the machine, the mixing mechanism being configured to mix selective quantities of components from the plurality of reservoirs according to specified ratios to create an aerosol-forming composition; a testing mechanism including a heater assembly configured to vaporize a test sample to form an aerosol, and at least one outlet configured to deliver the aerosol to the user; and a transfer mechanism configured to deliver the test sample to the testing mechanism. There is also provided a machine and process for producing and delivering the test sample.

Abstract: A method of reducing the amount of matrix-bound NNK in cured tobacco plant material is provided comprising reducing the amount of lignin in the cured tobacco plant material. A further method of reducing the formation of matrix-bound NNK during the curing of tobacco plant material is described comprising reducing the amount of lignin therein prior to curing.

Abstract: A rod for an aerosol-generating article is provided, including at least two sheets of tobacco material gathered together and circumscribed by a wrapper. The rod includes a first sheet of a first tobacco material and a second sheet of a second tobacco material. The second sheet of the second tobacco material is physically or chemically different to the first sheet of the first tobacco material.

Abstract: A rod is provided, formed from a first sheet including a tobacco material and a second sheet including a non-tobacco flavourant, the first and second sheets being gathered together and circumscribed by a wrapper. The rod may be used as a component part of an aerosol-generating article.

Abstract: The fastener is in a single piece and adapted to achieve the blind assembly and fixing of sumperimposed elements (A, B) provided with openings (C, D) which have a substantially square-shaped common part in which the fastener is engaged so as to fix together the element (A, B) after rotation of the fastener. For this purpose, it comprises a head (1) so shaped as to pass through the common part and connected to a rectangular-sided stem (3) so as to define two shoulders (4). This stem (3) is enlarged at one end in the form of a foot adapted to cooperate with the shoulders (4) by means of wings (6) of the foot to trap therebetween the elements (A, B).
