  • Patent number: 10619568
    Abstract: A system includes a controller configured to control a heated flow discharged from an outlet of a mixing chamber to an inlet control system to control a temperature of an intake flow through a compressor inlet of a compressor of a gas turbine system. The controller is configured to control a turbine extraction gas (TEG) flow to the mixing chamber. The controller is configured to control at least one of a pressurized flow of the compressor to the mixing chamber and a steam flow to the mixing chamber. The TEG flow is extracted through a turbine casing. The heated flow includes the TEG flow and the at least one of the pressurized flow and the steam flow.

  • Patent number: 10591547
    Abstract: A solid state circuit breaker, including a solid state switch, an inductor connected with the solid state switch in series and a fault detection circuit. The solid state switch has a gate electrode, a source electrode and a drain electrode. The fault detection circuit is used for detecting health status of the solid state switch and identifying fault type of the solid state switch in a condition that a fault occurs on the solid state switch based on one or more of a measured voltage between the source electrode and the drain electrode of the solid state switch, a measured voltage of two terminals of the inductor, a reference voltage and a switching control signal provided to the gate electrode of the solid state switch. A motor driving system having the solid state circuit breaker is further disclosed.

  • Patent number: 5796214
    Abstract: A ballast circuit for a gas discharge lamp comprises a resonant load circuit incorporating the gas discharge lamp and including a resonant inductance and a resonant capacitance. A d.c.-to-a.c. converter circuit induces an a.c. current in the resonant load circuit. The converter circuit comprises first and second switches serially connected between a bus conductor at a d.c. voltage and a reference conductor, and which are connected together at a common node through which the a.c. load current flows. The first and second switches each comprise a control node and a reference node, the voltage between such nodes determining the conduction state of the associated switch. The respective control nodes of the first and second switches are interconnected. The respective reference nodes of the first and second switches are connected together at the common node.

  • Patent number: 5345481
    Abstract: A boiling-water reactor plant employs a baffle that parallels the interior surface of a thermally-conductive containment wall, defining an intermediate condensate channel. When the plant turbine becomes isolated from the boiling-water reactor, the reactor is shut down and steam is released from the reactor pressure vessel to the containment. Steam rises through an opening at the top of the baffle, allowing some of the steam to condense on the interior surface of the containment. Condensate then flows into the channel, which is dimensioned so that noncondensable gases are dragged into the channel along with the condensate. This minimizes thermal insulation due to the noncondensables and enhances the transfer of heat from the containment. Furthermore, the noncondensable gases are dragged at a sufficient velocity to induce turbulence. The resulting mixing of condensate flow layers further improves heat transfer to the containment wall.

  • Patent number: 5292138
    Abstract: A split ring seal having an outer split ring and an inner split ring with the inner and outer split rings having overlapping portions. The split ring seal is located between a seating seal and a carrier and separates a high pressure cavity from a low pressure cavity. Movement of the split ring seal is restricted by sidewalls of the carrier. A diagonal edge on the outer ring reacts against centrifugal loading from the inner ring so that said outer ring is urged axially against a sidewall of the carrier to form a positive seal for blocking any leakage path between the high and low pressure cavities.

  • Patent number: 5077524
    Abstract: A method for obtaining high resolution NMR spectra without the need for phase cycling includes the application of magnetic field gradient pulses to select specific coherences. By using actively shielded gradients, a gradient pulse is applied during the evolution period of the selected coherence to dephase the transverse magnetization and another gradient pulse refocuses the desired coherences remaining during the acquisition period.
