  • Solenoid controlled cold head for a cryogenic cooler
    Patent number: 3991586
    Abstract: A solenoid control means for controlling the movement of a regenerator-diacer in a cryogenic cooler. The control means comprises sensing and power switching means for activating solenoids that assist in moving or restraining the movement of the regenerator-displacer in synchronism with pressure waves from a compressor.

  • Modified rotary compressor yielding sinusoidal pressure wave outputs
    Patent number: 3941522
    Abstract: A rotary compressor in which a slice is cut back under one rotor flank and continuous groove is cut in the rotor housing cover adjacent the slice and intersecting it. The two adjacent rotor flanks can be ported to prevent pressure buildup therein. This arrangement permits the volume under the modified rotor flank to be in constant communication with the compressor output and produce a true sinusoidally varying pressure output.
