  • Patent number: 11711902
    Abstract: Systems and methods for improved circuit board removal and/or reinstallation are provided. A circuit board removal system can include a frame including a channel arranged in a plate of the frame. A disengagement slider can include a mounting surface and a first portion including a first cam surface, where the disengagement slider is arranged within the frame. A separator can include a second cam surface and can be arranged in the channel of the plate. The first cam surface and the second cam surface can be nested with each other when the disengagement slider is in an inserted position. The disengagement slider can be configured to slide the separator in the longitudinal direction when the disengagement slider is removed from the frame due to the interaction of the first cam surface with the second cam surface.

  • Publication number: 20160273396
    Abstract: A power generation system includes: a first gas turbine system including a first turbine component, a first integral compressor and a first combustor to which air from the first integral compressor and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first integral compressor having a flow capacity greater than an intake capacity of the first combustor and/or the first gas turbine component, creating an excess air flow. A second gas turbine system may include similar components to the first except but without excess capacity in its compressor. A control valve system controls flow of the excess air flow from the first gas turbine system to the second gas turbine system. A heat exchanger may be coupled to the excess air flow path for exchanging heat with the excess air flow.

  • Publication number: 20160273408
    Abstract: A power generation system may include a gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied. The combustor is arranged to supply hot combustion gases to the turbine component, and the integral compressor has a flow capacity greater than an intake capacity of the combustor and/or the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to an exhaust of the turbine component. An eductor positioned in the excess air flow path uses the excess air flow as a motive force to augment the excess air flow with additional gas, creating an augmented excess gas flow.

  • Publication number: 20160273409
    Abstract: A power generation system may include a gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied. The combustor is arranged to supply hot combustion gases to the turbine component, and the integral compressor has a flow capacity greater than an intake capacity of the combustor and/or the turbine component, creating an excess air flow. A turbo-expander powers a generator. A first control valve controls flow of the excess air flow along an excess air flow path to the turbo-expander. An eductor may be positioned in the excess air flow path for using the excess air flow as a motive force to augment the excess air flow with additional air.
