  • Solid fuel nozzle tips
    Patent number: 10174939
    Abstract: A solid fuel nozzle tip for issuing a flow of mixed solid fuel and air to a boiler includes a tip body having an inlet and an outlet defining a longitudinal axis therebetween. The tip body includes a slot on an inlet side of the tip body extending in a direction parallel to the longitudinal axis. The slot includes an opening facing the inlet side of the tip body and a recess formed at an angle with respect to the longitudinal axis to at least partially retain a pivot pin. A solid fuel nozzle assembly for issuing a flow of mixed solid fuel and air to a boiler includes a solid fuel nozzle tip with a tip body, as described above, and a locking plate operatively connected to the tip body to assist in retaining a pivot pin within the slot of the tip body.
    Type: Grant

  • Weatherseal having a contact layer with thermoplastic particles in a thermoset carrier
    Patent number: 6406785
    Abstract: A weatherseal for repeatedly and releasably contacting a panel to provide a weather resistant seal therebetween. The weatherseal includes a substrate having a contact layer on the portion of the substrate that contacts the panel. The contact layer includes a multitude of surface treated ultra high molecular weight olefinic particles, such as ultra high molecular weight polyethylene, in a thermoset material such as cross linkable urethane, wherein some of the embedded particles define the area of contact between the weatherseal and the panel.
