Abstract: Apparatus and method are described for manufacturing a filter rod from a continuous multifilament filter tow which is treated with a smoke-modifying agent during the filter rod manufacturing process.

Abstract: A smokeless tobacco product is disclosed which contains cut or otherwise comminuted tobacco treated with a particulated gum composition that adheres as a discontinuous coating to the surface of the tobacco. The gum composition provides improved "gathering" characteristics and other benefits when the treated smokeless tobacco product is placed in the mouth of the consumer of such products.

Abstract: A variable air volume air conditioning system is disclosed which is capable of accurately controlling temperature and humidity levels in a conditional zone while achieving significant economy of operation.

Abstract: Apparatus is disclosed for withdrawing a bloomed, continuous multifilament filter tow from a jet device and conveying the filter tow to filter rod-forming means in such a way that compaction or compression of the filter tow prior to its entry into the rod-forming means is minimized.

Abstract: A combustible smoking material having a color other than that of conventionally cured tobacco leaves is coated with finely divided, toasted cereal grain to impart a tobacco-like brown color to the combustible smoking material.

Abstract: A combustible smoking material having a color other than that of conventionally cured tobacco leaves is coated with finely divided vermiculite that has previously been subjected to heat treatment to develop a brown color therein. The vermiculite coating imparts a tobacco-like brown color to the combustible smoking material.

Abstract: A filter tow blooming jet device for applying an additive to a continuous, multifilament filter tow is disclosed wherein the jet device is provided with orifice means transversely positioned in an elongated passageway through which the advancing filter tow passes and the additive is applied by nozzle means concentrically positioned with respect to the advancing filter tow at a point downstream of the orifice means. The additive may also be applied to the filter tow by nozzle means positioned adjacent to the wall surface of the elongated passageway or by injecting the additive into a stream of gaseous fluid introduced into the jet device for blooming the filter tow.

Abstract: Porous metal filters are adapted for use as liquid applicators for applying a liquid additive to a continuous, multifilament filter tow in connection with the manufacture of filter rods from the tow.

Abstract: A cold trap for collecting components of an aerosol stream comprises an elongated vessel provided with an aerosol stream inlet and an aerosol stream outlet, a cooling jacket for subjecting a substantial portion of the walls of the vessel to temperatures below 0.degree. C. and a baffle assembly that includes a plurality of spaced baffle plates which cooperate to present a tortuous path to the flow of the aerosol stream as it moves through the vessel.

Abstract: An improved jet device for treating a continuous, multifilament filter tow is disclosed wherein discharge means affixed to the exit end of the jet tube of the device are modified to present a smooth streamlined surface to the moving filter tow and to prevent accumulation therein of liquid addendum dislodged from the filter tow.

Abstract: Cut shredded or otherwise comminuted tobacco is treated with a volatile flavoring additive in a continuous process wherein the additive is combined with a polyhydric alcohol carrier and the additive/polyhydric alcohol combination is applied to the tobacco [by gas-atomizing spray nozzle means] under controlled conditions.

Abstract: A continuous process and apparatus for applying treating fluids to tobacco involves a vertically disposed tower or chamber that is provided with tobacco inlet and outlet means, a plurality of cooperating, vertically spaced baffles arranged in alternating fashion and a plurality of spraying devices located within the tower or chamber at points intermediate the inlet and outlet means. Tobacco and treating fluid are introduced into the tower or chamber at controlled flow rates via the tobacco inlet means and spraying devices, respectively, to give tobacco treated with the desired quantities of treating fluid.

Abstract: Filter-tipped cigarettes, cigars and similar smoking products which employ self-supporting non-wrapped fibrous filters are disclosed wherein the tobacco-containing portions are attached to the fibrous filters by tipping paper that is coated in a specified manner with a hot-melt adhesive.

Abstract: Loss of texture in vegetable and fruit material caused by heating such material in connection with the preservation thereof can be minimized by contacting the fresh vegetable and fruit material with certain organic compounds for a short period of time and then removing the organic compound by rinsing the material with water or a water-based medium prior to heating the vegetable and fruit material.

Abstract: Filter-tipped cigarettes, cigars and similar smoking products which employ self-supporting non-wrapped fibrous filters are disclosed wherein the tobacco-containing portions are attached to the fibrous filters by tipping paper that is coated in a specified manner with a hot-melt adhesive.

Abstract: Glucose is converted to fructose in the presence of an enzyme produced by Flavobacterium arborescens.

Abstract: This invention relates to a process for expanding tobacco wherein tobacco impregnated with an expansion agent is rapidly heated in the presence of a fluidized bed of hot inert solid particles to effect expansion of the tobacco.

Abstract: A stationary elongated vessel of substantially circular cross section having side walls and end closures is provided with a plurality of rod-like projections rigidly secured to and extending radially inwardly from the side walls at predetermined locations. A rotatably supported shaft concentrically positioned within the vessel is provided with a plurality of finger-like appendages rigidly secured thereto and extending radially outwardly from predetermined locations on the sides of the shaft. Support means maintain the concentric position of the shaft and restrict axial movement of the shaft so that the finger-like appendages intermesh with the rod-like projections in non-contacting relationship during rotation of the shaft. Inlet and outlet means are provided to introduce into and withdraw from the vessel liquids and aerosol streams. Rotation of the shaft at appropriate speeds provides effective contact between the liquid medium and the aerosol stream in the vessel.
