    Abstract: A system for cooling and recuperative heating of a slurry in a metallurgical process which includes heat exchangers, pumps and autoclaves is described herein. The heat exchangers use a non-scaling common liquid heat transfer medium. Preferably, the heat exchangers are tube-in-tube heat exchangers with 3 to 7 slurry tubes in each heat exchanger. An advantage of this system is that it does not use flash tanks. To minimize abrasive wear on impinged surfaces, the velocity of the slurry is not more than 5 meters per second. The slurry comprises a solids concentration of 25% to 50%. Preferably, the pumps in the system are float-type pumps in which the driven liquid from the discharge pumps is also used as the drive liquid for the feed pumps.

    Abstract: A method of protecting a cylinder of a compressor comprising a piston, a linear permanent magnet (PM) having a coil and a magnet, and a sensor-less control of the PM for moving the piston in and out of the cylinder. The method including the steps of receiving a reference position of the piston from a temperature control loop; deriving a compensation voltage and a load spring effect information from a current through the coil; providing a model input voltage to a model of a mechanical structure of the compressor for predicting position of the piston, the model input voltage comprising a first voltage derived from the reference position; a compressor input voltage comprising the first voltage and the compensation voltage; and using a position control loop to recognize when the maximum compression ratio is desired and controlling the piston to achieve maximum compression ratio without causing damage to the discharge valve.

    Abstract: A prime mover includes a shaft assembly that is supported for reciprocal movement between first and second ends of a stroke, and that includes first and second portions having a first material, and a third portion in between the first and second portions, having a second material, different from the first material. A single inductive proximity sensor makes a first indication when proximate the first material, and makes a second indication, when proximate the second material. A portion of the sensor is proximate the first portion when the shaft is at the first end of the stroke, the same portion of the same sensor is proximate the second portion when the shaft is at the second end of the stroke, and the same portion of the same sensor is proximate the third portion the entire time the shaft is in between the first and second ends of the stroke.
