  • Publication number: 20110241443
    Abstract: In accordance with various aspects of the present invention, a method and circuit for reducing power consumption of a power strip is provided. In an exemplary embodiment, a power strip is configured for reducing or eliminating power during idle mode by disengaging an outlet from power input. A power strip may include two or more outlets and two or more outlet circuits, with AC power input connected to the outlets through the outlet circuit(s), which may include a current transformer, a control circuit, and a switch. The current transformer secondary winding provides an output power level signal proportional to the outlet load. If behavior of the current transformer secondary winding indicates that the outlet is drawing substantially no power from the AC power input, the switch facilitates disengaging of the current transformer primary from the outlet.

  • Patent number: 5533338
    Abstract: A process and system for removing condensable vapors contained within the gas stream in accordance with the process and system, condensable vapors contained within the gas stream are condensed within one or more condensers through indirect heat exchange of the gas stream with a refrigerant stream. This produces a refrigerated gas stream and a heated refrigerant gas stream. Further heat is exchanged from at least part of the heated refrigerant stream to the refrigerated gas stream and in economizing heat exchanger to form a cooled refrigerant stream from the heated refrigerant stream. The refrigeration stream is produced by combining a cryogenic stream with the at least part of the cooled refrigerant stream in a mixing chamber of an ejector or analogous equipment.
