  • System and method having control for solids pump
    Patent number: 9970424
    Abstract: A system includes a solid feed fuel pump configured to route a solid fuel flow from an inlet to an outlet. The solid feed fuel pump includes an actuated valve that is disposed within the outlet. The actuated valve is configured to adjust a compaction of the solid fuel flow while in the outlet. The actuated valve adjusts the compaction in response to active control based on sensed feedback from the system.
    Type: Grant

  • Apparatus for applying tension to studs
    Patent number: 4604918
    Abstract: A stud tensioning apparatus includes an array of arcuate jaw segments that are movable inwardly to cause grooves on the segments to engage the threads of the studs. The tensioning force is applied to the segments by a pull member that has hangers received by apertures in the segments. The hangers fit loosely into the apertures, permitting the segments to move pivotably in two perpendicular directions to compensate for misalignment between the stud and the tensioning apparatus.
