Abstract: A pulper for pulping a fiber suspension includes a vessel, an extraction plate assembly and a rotor. The extraction plate assembly is disposed within the vessel and includes a metal plate with a plurality of holes extending therethrough. A plurality of metal inserts are respectively disposed within the holes and project from the plate. Each insert is removably attached to the plate. A rotor is disposed within the vessel adjacent to the extraction plate assembly. The inserts are removably attached to the plate by brazing the inserts within the holes, or slightly shrinking the inserts using liquid nitrogen and placing the inserts in the holes.

Abstract: A fuel control valve (100) includes a rotary throttling valve assembly (4,7) providing one or more of the benefits of being lightweight, having a relatively low power consumption, having a fail-closed structure and/or zero leakage. The fuel control valve (100) is a rotary, throttling valve that is actuated via a rotary torque motor (70). The valve (7) can be spring loaded for providing positive shutoff. Position indication of the valve (7) is obtained via a position sensor (31) and cam (13) mounted to the throttling valve shaft at a driven end (98). In a de-energized state, a torsion spring (45) is provided that is loaded to rotate the valve (7) to the closed position. The fuel control valve (100) may be advantageously utilized in extreme operating environments, e.g., such as extreme temperature and vibration environments found in missile control fuel systems.

Abstract: A fuel control system (10) in a turbine engine includes a centrifugal boost pump (20) that receives fuel from a fuel tank and increases the pressure of the fuel. A piston pump (40) boosts the fuel pressure to levels required by the turbine engine and meters an amount of fuel delivered to the turbine engine. A speed controlled electric motor (30) drives the piston pump (40). The electric motor (30) is driven by an electronic speed control wherein by controlling motor speed, fuel flow to the turbine engine is controlled, and fuel flow is directly proportional to the speed of the motor (30). Accordingly, the system (10) seeks precision of fuel control that can be achieved with an accuracy of better than +/−3% over a 30:1 fuel flow range.
