  • Patent number: 7568642
    Abstract: An apparatus for installation of a material having discrete elements. The apparatus includes a supply material having discrete elements and a transporter system downstream of the supply material having discrete elements. In embodiments, the transporter system includes: a high speed, inline blower; a material agitator upstream of the inline blower, the material agitator including a plurality of concentric rings with serrations on the upper surface of each arm, wherein at least one outer ring includes saw tooth serrations on the upper surface of the ring; a transmission connected to the shaft of the blower for providing a lower speed mechanical output to the material agitator; and an orifice substantially adjacent to the inlet of the blower for receiving the supply material having discrete elements. In embodiments, the apparatus further includes an applicator assembly connected downstream to the transporter system.

  • Patent number: 7279073
    Abstract: An apparatus for treating fibrous material is disclosed. The apparatus may include a fiber separator, a de-liquefier, a dry-to-wet blender and a flash dryer. The fiber separator may be a liquid-based fiber separator. The de-liquefier is for removing liquid from the fibrous material. The blender downstream, which may be a dry-to-wet blender, is for adding a dry material to the de-liquefied fibrous material. The de-liquefier and a dry-to-wet blender are downstream from the fiber separator and the dry-to-wet blender may be downstream from the de-liquefier. The flash dryer, which is even further downstream, is for drying the treated fibrous material.
