  • Tilt pad bearing with through-pivot lubrication
    Patent number: 9739310
    Abstract: A tilt pad bearing may include a support structure having first and second support structure surfaces. A pivot may have first and second pivot surfaces, and the first pivot surface may be coupled to the second support structure surface. A pad may have first and second pad surfaces, and the first pad surface may be coupled to the second pivot surface. A path of fluid communication may extend from the first support structure surface, through the pivot, and to an opening in the second pad surface.
    Type: Grant

  • System and method of expanding a fluid in a hermetically-sealed casing
    Patent number: 8961120
    Abstract: An expander-generator is disclosed. The expander-generator is disposed within a hermetically-sealed housing and includes a high-pressure expander stage and a low-pressure expander stage. A working fluid, such as ammonia, is introduced into the high and low pressure expander stages and expanded therein so as to provide rotational torque to a shaft. A generator, such as a motor, pump, or compressor, may be coupled to a free end of the shaft such that rotation of the shaft will provide useful work for the generator.
