Abstract: A multi-sectional filter tip assembly is initially made with two charcoal filter sections and alternate sections of cellulose acetate fibrous material with a fibrous section at each end. The filter tip assembly is then compacted by a pin compactor which punches a recess into each fibrous end of the filter tip assembly while at the same time forcing the displaced acetate fibrous material into the charcoal sections to compact the charcoal. Upon removal of the pins of the pin compactor, a recess is formed in each end of the filter tip assembly.

Abstract: A filter tipped cigarette includes a cylindrical tobacco section and a cylindrical filter axially aligned therewith. The filter is comprised of an axially aligned tube extending from said tobacco section, a layer of filter material positioned circumferentially about said tube and a diffuser adjacent an end of the tube for dispersing the smoke received from the tube prior to entering the smoker's mouth.

Abstract: A process for improving, enhancing or modifying the organoleptic properties of tobacco products which comprises adding thereto a compound selected from the group of alpha-cyclogeraniol, beta-cyclogeraniol, and certain ether, ester, thiol and thioether derivatives thereof.

Abstract: The apparatus employs two pairs of cutting discs which are diametrically spaced apart on a rotating drum to sever two filter plugs at a time from a travelling rod of filter material. The plugs are cut in uniform size, for example, in sizes between 5 millimeters and 14 millimeters and can be subsequently spaced apart so as to receive charcoal or other particulate filter material in the intermediate spaces. The drum rotates in synchronism with a recessed ledger through which the respective pairs of cutting discs pass to sever the travelling rod of filter material. Sharpening means are provided to maintain the cutting discs sharp.

Abstract: This invention relates to a cigarette filter composed of two concentric cylindrical layers of fibrous filter materials, in which the inner cylindrical layer has a lower draw resistance than the outer cylindrical layer, and a method and apparatus for the manufacture thereof.

Abstract: The sensing and correcting apparatus is employed in a machine for making cigarette filter rods containing hollow tubes on a continuous in line basis. The apparatus senses the position of the hollow tubes in a stream of tow and corrects the insertion position of subsequent hollow tubes if the position of the inserted tubes does not coincide with the proper cutting position. Sensing is accomplished by measuring the density of the moving stream and generating a position signal in response for comparison with a reference signal generated on cutting of a filter rod. If there is a difference exceeding acceptable tolerance limits, the comparison means generates a correction signal which is delivered to a timing assembly in the transmission for inserting the hollow tubes.

Abstract: The apparatus employs two cutting discs which are spaced apart from each other laterally to sever plugs of different lengths from a travelling rod of filter material. The plugs alternate in size, for example, between 24 millimeters and 14 millimeters and are subsequently spaced apart so as to receive charcoal or other particulate filter material in the intermediate spaces. The resulting filter has the charcoal chamber closer to the tobacco end of the cigarette than to the exposed end of the cigarette. The cutting discs are mounted on a drum which rotates in synchronism with a recessed ledger through which the respective cutting discs pass to sever the travelling rod of filter material.

Abstract: An apparatus for the high speed transportation of cigarette filter rods from a magazine containing the rods to a transfer drum. The apparatus has a magazine, a downwardly extended chute connected to the magazine adapted to receive filter rods singularly, a rod separation means at the junction of the magazine and chute, and a vacuum means adjacent to the chute exit. The vacuum means creates a negative pressure within the chute to hold the lowermost rod in the chute in a fixed position for accurate transfer to the transfer drum.

Abstract: The amount of polycyclic aromatic hydrocarbons in tobacco smoke is reduced and a substantially diminished biological activity of the tobacco smoke condensate when evaluated on experimental animals following conventional protocol is achieved by adding to the tobacco palladium, either in metallic or salt form, and an inorganic nitric oxide generating compound.

Abstract: The machine produces a filter rod made up of a cylinder of tow and spaced apart hollow plastic tubes within the tow. The machine includes a means for supplying a continuous tow stream to an injection station below a rotatable wheel which delivers the plastic tubes in spaced apart fashion. Plungers on the wheel eject the tubes from the wheel and positively push the ejected tubes into the cylinder of tow at the injection station. The tubes are cut from a continuous tubing by means of a cutter which is timed with respect to the operation of the machine. The cut tubes are initially pushed forward on the wheel by a pushing roll and thereafter slid backwardly by a cover so as to be properly positioned for injection into the tow.

Abstract: This invention relates to a cigarette filter composed of two concentric cylindrical layers of fibrous filter materials, in which the inner cylindrical layer has a lower draw resistance than the outer cylindrical layer.

Abstract: The apparatus is constructed to produce a hollow filter rod. The apparatus includes a mandrel through which a supplied length of tubing is passed, a nozzle surrounding the mandrel for shaping a stream of fibrous filter material about the mandrel and a forming means for enveloping a web of paper about the fibrous filter material and the tubing to produce the filter rod. The mandrel can be adjusted relative to the forming means to ensure an accurate centering of the tubing within the filter rod.The hollow filter includes a rigid non-deformable tube defining a smoke passage having a draw resistance to control the amount of unfiltered smoke, a concentric layer of filter material and a perforated outer wrap for passage of air into the layer of filter material.

Abstract: The cigarette mouthpiece is made of one-piece construction in which two semi-cylindrical shells are hinged together along one edge and are releaseably secured together at the free edges. The mouthpiece has an internal cylindrical smoke chamber which is separated from a tobacco column at one end by a baffle means while the opposite end of the smoke chamber is defined by a pair of abutting walls which are each slotted to define an orifice. The orifice is of a predetermined diameter less than the diameter of the smoke passage to control the amount of smoke flowing out of the smoke passage for a given draw. The exterior surface of the mouthpiece is provided with longitudinal grooves which cooperate with an overlying perforated tipping paper to define flow paths for ventilation air. For a given draw, an amount of undiluted unfiltered smoke is drawn from the tobacco column into the smoke chamber and through the outlet orifice.

Abstract: The first conveyor is inclined to move the cigarettes from the cigarette making machine upwardly in single line fashion to the second conveyor which conveys the cigarettes horizontally in stacked fashion into the hopper of the cigarette packaging machine. The packaging machine is linked in a one-to-one relationship with the cigarette making machine and is capable of high speed production of at least 3600 cigarettes per minute.

Abstract: A method of forming a bright-drying floor finish on a resilient flooring comprising applying a polish containing an aqueous dispersion of fine particles of a resin with a Tg of 30.degree. to 80.degree.C to a flooring, preferably a resilient flooring, with at least one of said polish or said flooring having been preheated to a temperature above the glass transition (Tg) temperature of said resin, and drying said polish to produce said bright-drying floor finish.
