Abstract: This invention relates to the control of the burn rate of a cigarette. The burn rate is controlled by the use of a paper wrapper to which regions of cellulosic material is applied and bonded. The cellulosic material is applied during a manufacturing step for the base paper wrapper, either off or on-line of the paper wrapper-forming machine.

Abstract: A flavor source to be used as a thermally releasable flavorant for smoking articles that do not combust tobacco. The flavor source includes tobacco particles, an aerosol precursor that forms an aerosol upon exposure to heat, and a gelling agent that imparts sufficient structural framework for rigidity to the flavor source. The material is mixed, extruded through a die, and cut into the shape of a one-piece flavor source. The flavor source is loaded into a chamber for inclusion in a smoking article as a flavor generator.

Abstract: Apparatus for winding the stator of an electric motor with two wires simultaneously are provided. The apparatus includes a stator winding needle having two separate wire delivery channels. The leads of the two wire to be wound are passed through the winding needle and are held by start lead holders. When winding is complete, the wires are identified by a lead pulling apparatus which rotates in a predetermined direction to grip an appropriate wire. The lead pulling apparatus draws each of the wires to a termination lead holder. Each wire is gripped and cut by a gripping assembly, which holds the cut leads in a predetermined position to facilitate winding of a subsequent stator.
