  "abstract": "Apparatus for dispersing pneumatically conveyed pulverulent material particularly adapted for use in dispersing pulverulent material throughout the fluid bed of a fluidized bed reactor. The apparatus includes plates which are formed in an X shape with other plates mounted at an angle to the longitudinal axis of the first plates between the branches of the X shape. The apparatus extends into the open end of the conveying pipes and into the material chamber of a fluid bed reactor. The apparatus serves to disperse the particulate material in the fluid bed.",
  "claims": [
    "1. A fluidized bed reactor including a vessel, gas permeable grid means dividing the vessel into an upper material chamber and a lower plenum chamber and adapted to support a bed of material in the material chamber, means for supplying gaseous fluid to said plenum chamber for passage through said grid to fluidize the bed of material; and conduit means for conveying a stream of pulverulent material to be processed from a source to material to the the improvement comprising means mounted in said conduit means and extending into said material chamber for dividing the stream of pulverulent material and dispersing the divided portions of the stream upwardly and outwardly into the fluidized bed of material.",
    "2. A fluidized bed reactor according to claim 1 wherein the means mounted in the conduit means for dividing the stream of pulverulent material includes primary plate means which is an X shape mounted in the end of said conduit means and extending into the material chamber for dividing the stream of pulverulent material, and a plurality of secondary diamond-shaped plate means each mounted on said primary plate means in the material chamber between the branches of the X shape; each of said diamond-shaped plate means further dividing each of said divided portions of said stream into at least two flow paths and dispersing the divided portion of the stream upwardly and outwardly into the fluidized bed of material.",
    "3. Apparatus for pneumatically conveying pulverulent material from a source to a point at which the material is to be used comprising: conduit means adapted to be connected at one end to a source of gaseous fluid and at its other end to the point at which the material is to be used and having an open end at the point at which the material is to be used; means for admitting pulverulent material into the conduit means whereby a stream of pulverulent material is conveyed in said conduit means; and means mounted in the open end of said conduit means for dividing the stream of pulverulent material and dispersing the divided portions of the stream upwardly and outwardly including primary plate means having an x shape mounted in the end of said conduit means and extending out of said conduit means into the material chamber and a plurality of secondary diamond-shaped plate means each mounted on said primary plate means in the material chamber between the branches of the x shape; each of said diamond-shaped plate means further dividing each of said divided portions of the stream into at least two flow paths.",
    "4. A fluidized bed reactor according to claim 2 wherein the primary plate means having an X shape is formed from at least two substantially flat plates and the secondary diamond-shaped plate means are formed from a plurality of substantially flat plate means.",
    "5. Apparatus for pneumatically conveying pulverulent material from a source to a point at which the material is to be used according to claim 3 wherein the primary plate means having an X shape is formed from at least two substantially flat plates, and the secondary diamond-shaped plate means are formed from a plurality of substantially flat plates."
