  • Patent number: 6782892
    Abstract: Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes which involve the use of manganese oxide mixtures that include nanoparticle manganese oxide and other nanoparticle additive(s) capable of converting carbon monoxide to carbon dioxide and/or converting nitric oxide to nitrogen. The compositions, articles and methods of the invention can be used to reduce the amount of carbon monoxide and/or nitric oxide present in mainstream smoke reaching the smoker and/or given off in secondhand smoke. The manganese oxide can be co-precipitated with the additive(s), or mechanically mixed with the additive(s) to form the manganese oxide mixture. The manganese oxide may have a lower light-off temperature than the additive, such that during smoking of the cigarette, the heat generated from the oxidation of carbon monoxide by manganese oxide is capable of activating the additive. The additive may include iron oxide (Fe2O3) nanoparticles.

  • Patent number: 6782890
    Abstract: The distributor of a cigarette rod making machine employs a zig-zag sifter which receives a mixture of tobacco ribs and shreds from a reservoir by way of a duct or an elevator conveyor. The shreds leave the uppermost stage of the sifter and are conveyed, by a Coanda separator, into an upright gathering duct which discharges shreds for delivery onto the concave surface(s) of one or more guides serving to direct one or more streams of shreds against the underside(s) of one or more foraminous belt conveyors which advance the stream(s) past one or more trimming devices serving to remove the surplus and to thus convert each stream into a rod-like filler which is ready to be draped into a web of cigarette paper. The removed surplus is returned into the reservoir or directly into the zig-zag sifter.

  • Patent number: 6782891
    Abstract: The components of cigarette smoke, known until now, do not explain the overwhelming hazardous effects of smoking; this invention describes the isolation, identification and procedures for determination of the structure, properties and assay of a relatively stable major harmful oxidant (cs-oxidant) present in the cigarette smoke, the content of which is about 190±10 &mgr;g per cigarette; the cs-oxidant alone almost quantitatively accounts for the oxidative damage of proteins produced by the aqueous extract of whole cigarette smoke, it is also responsible for the oxidative damage of DNA; since the cs-oxidant is relatively stable, it further explains the deleterious effects of the side stream smoke and passive smoking; a number of chemical compounds/agents including vitamin C have been found to prevent the cs-oxidant induced protein oxidation in vitro.

  • Patent number: 6779530
    Abstract: A process for reducing the permeability of a paper wrapper used in the construction of a smoking article is disclosed. The paper wrapper is treated with a film-forming composition that forms treated discrete areas on the wrapper. The treated discrete areas have a permeability within a predetermined range sufficient to reduce the ignition proclivity properties of a smoking article made with the wrapper. In accordance with the present invention, the film-forming composition contains a film-forming material. The film-forming material has a relatively low viscosity. In this manner, the film-forming composition can have a relatively high solids content and still be applied to the wrapper using conventional techniques, such as by using a gravure printer.

  • Patent number: 6779528
    Abstract: Fibers are produced from an acetone solution of cellulose acetate by pulling or extruding such material through a spinneret in a dry spinning process. A vacuum is applied to the thus formed fibers after a certain degree of drying. A dried outer skin is formed, and the vacuum causes the solvent inside the skin to explode or pop and exit the fiber along micro-porous paths thereby producing high surface area fibers with micro-porous cavities and internal void volume. Such micro-cavities are particularly useful for retaining solid and/or liquid reagents in a cigarette filter for selective filtration of various smoke components.
