Abstract: A process for manufacturing reconstituted tobacco with reduced nitrogenous content by submitting cured tobacco material, including whole leaf, stems, scraps, fines and lamina, as well as burley leaf and stem, to an extraction with a solution containing sodium acetate, sodium hydroxide, potassium hydroxide or mixtures thereof. The extraction process, in addition to denitrifying the tobacco material, also produces reconstituted tobacco paper with characteristics similar to flue cured tobacco leaf.

Abstract: A device and method for enabling a user to draw upon a liquid contained within the device includes a container, a holder for fastening the container to a principal apparatus, a conduit for carrying liquid, and a support for rigidly supporting the conduit in a variety of positions adjacent the user's mouth. The method includes providing the device, fastening the device to the principal apparatus in a manner that resists vibration, and positioning an outlet of the conduit adjacent to the user's mouth so as to enable the user to drink with only slightly moving his head or mouth. Therefore, the device and method may be employed to enhance independence of persons with disabilities, among other uses.

Abstract: A process for the manufacture of a reconstituted tobacco product wherein the process comprises extraction of tobacco furnish with an aqueous solvent in the presence of at least one ammonium salt or urea or a urea derivative or a mixture of urea or a urea derivative and at least one ammonium salt to provide an aqueous solvent extract and a fibrous material and forming the fibrous material into a sheet-like product using the papermaking process. The aqueous extract is then applied to the formed sheet-like material and further processing provides a reconstituted tobacco product having improved smoke quality.
