  2. Limit switch - Wikipedia

    en.wikipedia.org/wiki/Limit_switch

    A limit switch with a roller-lever operator; this is installed on a gate on a canal lock, and indicates the position of a gate to a control system A limit switch mounted on a moving part of a bridge In electrical engineering , a limit switch is a switch operated by the motion of a machine part or the presence of an object.

  3. Open-circuit saturation curve - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_saturation_curve

    A diagram with multiple synchronous machine curves; open-circuit saturation curve is the leftmost one The open-circuit saturation curve (also open-circuit characteristic, OCC) of a synchronous generator is a plot of the output open circuit voltage as a function of the excitation current or field.

  4. Open collector - Wikipedia

    en.wikipedia.org/wiki/Open_collector

    Open drain output uses MOS transistor (MOSFET) instead of BJTs, and expose the MOSFET's drain as output. [ 1 ] : 488ff An nMOS open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate.

  5. Heat recovery steam generator - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_steam_generator

    A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).

  6. Thermal cutoff - Wikipedia

    en.wikipedia.org/wiki/Thermal_cutoff

    A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip , often encased in a tubular glass bulb to protect it from dust or short circuit .

  7. Infinite switch - Wikipedia

    en.wikipedia.org/wiki/Infinite_switch

    The infinite switch itself was described in a 1975 patent of George F. Esker Jr. and Otto J. Cousins of the Harper Wyman Company. This switch would reset itself as the bi-metallic strip cooled, provided a cycle of calibrated opening and closing. It also provided an indicator light that remained on as long as the knob was not in the closed position.

  8. Open-circuit test - Wikipedia

    en.wikipedia.org/wiki/Open-circuit_test

    Circuit diagram for open-circuit test. The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of ...

  9. United States Penitentiary, Coleman - Wikipedia

    en.wikipedia.org/wiki/United_States_Penitentiary...

    It is part of the Coleman Federal Correctional Complex (FCC Coleman) and is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. USP Coleman I was opened in 2001, and in 2004 Clark Construction completed a 555,000-square-foot (51,600 m 2) additional component for USP Coleman II.
