摘要： A cigarette is provided which comprises a tobacco rod 1, and an integral axially aligned substantially cylindrical assembly at the mouth end of the cigarette which preferably includes a wrapped cylindrical filter plug 7, 8 and tipping paper 2, and which is provided with means to adjust the air dilution value of the cigarette. The assembly has first and second ends, which are open to permit the passage of air and smoke, and at least two openings 6 in addition to the open ends. Means are provided for rotating one opening relative to the other so that the openings are in varying degrees of registry to permit varying amounts of air to combine with and dilute the smoke. In accordance with another aspect of the invention a filter cigarette is provided which has a wrapped filter plug 202, 203 aligned in end-to-end abutting relationship with a substantially cylindrical tobacco rod 201. The filter plug and tobacco rod are circumscribed and joined by a substantially air permeable first layer of tipping paper 204. Circumscribing the first layer of tipping paper is a second layer of substantially air impermeable tipping paper 206. The second layer has a circumferentially extending row of closely spaced perforations 210 intermediate the two ends of the second layer which divides it into a mouth-end sleeve 207 attached to the first layer at the mouth end of the cigarette and a second rod-end sleeve 208 detachable from the mouth end sleeve by rotating the sleeve relative to the first sleeve so that it can move axially between the mouth-end sleeve and positions along the tobacco rod allowing airto enter the filter through the exposed portions of the air permeable layers.

摘要： A hydrophilic polymer membrane or membranes (17, 18 and 19) for separating tar and other toxic components from tobacco smoke. The membrane having a controlled pore size that is prepared in an oil in water system where the water is the continuous phase and the oil phase contains the polymer. More particularly, the present invention relates to a membrane comprising a cross-linked, water insoluble hydrophilic polymer having micropores of a controlled porosity. Suitable polymers include cellulosics, polyvinyl alcohol, polyvinyl formal, polyviral pyrrolidone, polyacrylic acid, polyfurfuryl alcohol and compatible mixtures thereof. Water soluble silicone polymers, for example silane terminated polyorganosilanes such as polydimethylsilofane, polyoctamethyltrisilofane and polyhexamethyldisilofane, are also suitable.

摘要： Un filtre pour fumee de cigarette est forme par un organe generalement tubulaire (10) ayant une premiere paroi formant barriere (24) s'etendant en travers de la region mediane de son interieur. La fumee est acceleree depuis la chambre d'amont vers la chambre d'aval (50) dans le filtre au travers d'une petite ouverture d'acceleration (26) dans la region mediane de cette barriere. Une cible ou barriere d'aval (28) dont la surface n'est pas superieure a la surface de la section de l'ouverture d'acceleration, est placee en aval de l'ouverture a une distance qui, de preference, n'est pas superieure au diametre de l'ouverture d'acceleration. Des ailettes de recuperation (52-56) a l'extremite d'amont de la chambre d'aval (50) sont formees en amont de la barriere (24) et leur action se combine a l'action de la cible (28) pour separer les liquides et les semi-solides de la fumee et les recuperer a l'extremite d'amont de la chambre d'aval (50).

摘要： A continuous rod of a product such as cigarette filter material is coated with a treating liquid by being passed axially through a cylindrical applicator zone comprising a permeable cylindrical wall, the cylindrical wall being concentrically enclosed within a reservoir and manifold zone connected to a source of liquid. The feed supply forthe liquid additive can be pressurized and/or heated, so that application of the additive can be in either liquid or vapor form. The process and apparatus of this invention may be used alone or in conjunction with prior art homogeneous applicators and processes. When used to apply a plasticizer to a rod of continuous filament tow, e.g. for use in producing cigarette filters, annular regions of varying concentrations of the plasticizer are produced in the rod. A relatively dense region of plasticized fiber can be produced on the outside of the filter. Filter rods having wrapping paper uniformly adhered about the periphery of the rod can be produced. By installing the applicator apparatus between the transport jet and the garniture tongue of a typical cigarette filter rod making machine, the invention permits the production of satisfactory paper wrapped filter rods having unique depression on loading characteristics,

摘要： The present invention relates to a process for producing a tasteless carbon heat source from a preformed article of a lingo-cellulosic material according to which the article is pyrolyzed in a continuously exchanged inert atmosphere at a temperature within the range of from about 800° to about 1100 °C, for from about 0.5 to abour 3 hours, then cooled in the inert atmosphere at a rate of from about 500° to about 10°C per hour to a temperature within the range of from about 275°C to about 25°C, and then subjected to at least one additional process step selected from an oxygen absorption step, a salt impregnation followed by heat treatment step, and a water desorption step. The present invention also relates to a smoking article including the carbon heat source, and a flavor generator comprising a substrate material containing at least one thermally releasable flavorant.

摘要： A filter tow blooming jet device (14) for applying an additive to a continuous, multifilament filter tow is provided with orifice means (20) transversely positioned in an elongated passageway (21) through which the advancing filter tow passes. Additive is applied to the tow by nozzle means (60) concentrically positioned with respect to the advancing filter tow at a point downstream of the orifice means (20). The additive may additionally be applied to the filter tow by nozzle means (38,42) positioned adjacent to the wall surface of the elongated passageway (21) or by injecting the additive via a nozzle (50) into a stream of gaseous fluid introduced into the jet device via conduit (18) for blooming the filtertow.

摘要： A tobacco smoke filter comprising a rod (314) of smoke filter material having a thin plastics sleeve (318) extruded therearound, the outer surface of the sleeve conforming to the outer surface of the rod. The sleeve is suitably at least 100 times thinner than the greatest transverse dimension of the rod, and may be of the same material as the rod. The sleeve may be extruded over the rod with application of suction via the rod to vacuum from the sleeve to the rod periphery, especially if the rod has previously been grooved and/or squashed over parts of its length to a reduced cross-section.

摘要： Waste or other recovered fibrous material, for example fibres from waste or reject cigarette filters, filter rods and tows employed in making them, is converted into useful products by depositing the fibres 11, preferably dispersed in an aqueous medium 12, on an advancing screen 16 to form a fibrous web. The web is caused to adhere to a carrier or backing sheet 14, either during or after deposition, and the assembly 20 of fibres and carrier is sub-divided into portions for the manufacture of fibrous products, preferably after being dried in a ventilated drier 21. Plasticizer may be applied by an applicator 22 for the purposes of softening and bonding the fibres in subsequent stages of the production of the desired fibrous products. The divided portions of the assembly 20 can be used to form such products as cigarette filters or absorbent ink carrier elements for pens.

摘要： The present invention relates to high speed processes and apparatus for the manufacture of cigarette filter rods. In accordance with this invention it has been discovered that in a process of manufacturing filter element from opened and deregistered crimped continuous filament tow, wherein said tow is conducted from a mechanical forwarding means through an aspirating jet positioned adjacent a compacting means, and wherein means are provided for dissipating aspirating fluid, that filter rod pressure drop and weight variations are reduced by causing the opened and deregistered tow to contact a drag inducing tow width and direction controlling means positioned substantially intermediate said mechanical forwarding means and said aspirating jet.
