    摘要: Cigarette filter rods having individual pellets positioned at predetermined intervals therein are prepared by cutting a strand of plasticized material into pellets which are then inserted into a web of filter tow. A wheel having a series of grooves is rotated within a rim-like housing, and introduction of a plasticized flavor-containing strand into each groove results in a cutting of the strand into pellets of the desired size. Each pellet is positioned within the moving web of tow. The web filter material and the pellets positioned within the web are introduced into a rod-making unit wherein the rod is formed. The rate of feed of the strand, the rate of feed of the filter tow, the rate of rotation of the grooved wheel and the rate of pellet formation are controlled relative to one another such that pellets of well controlled size are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.

    摘要: Rods are manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands of about 1/32 inch width. The strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod. The continuous rod is severed at regular intervals to provide a plurality of rods of the desired length. The resulting rods have a plurality of substantially longitudinally extending strands provided from shredded sheet-like material. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.

    摘要: CATALYTIC CRACKING APPARATUS COMPRISING AN ELONGATED TRANSFER LINE CONDUIT CONNECTED TO A RECEPTION VESSEL SAID TRANSFER LINE CONDUIT BEING CONNECTED TO A SERIES OF CYCLONE SEPARATION MEANS WHICH AR WITHIN SAID RECEPTION VESSEL. THE TRANSFER LINE CONDUIT IS CONNECTED TO THE INLET OF A FIRST CYCLONE SEPARATION MEANS WHICH IS LOCATED WITHIN THE RECEPTION VESSEL. THE FIRST CYCLONE SEPARATION MEANS CONTAINS AN INLET WHICH IS IN COMMUNICATION WITH THE INTERNAL PORTION OF SAID RECEPTION VESSELS. THE FIRST CYCLONE SEPARATION MEANS IS CONNECTED TO A SECOND CYCLONE SEPARATION MEANS WHICH ACCEPTS MATERIAL FROM THE OUTLET OF SAID FIRST CYCLONE SEPARATION MEANS AND PASSES A PORTION OF THOSE MATERIALS OUT OF THE SECONG CYCLONE SEPARATION MEANS THROUGH AN OUTLET WHICH PASSES OUT OF THE RECEPTION VESSEL.
