Publication number: 20170052087Abstract: A method for detecting leakage at a fluid connection for a gas turbine fuel supply system is disclosed herein. The method includes closing a flow control valve at an upstream end of the fuel supply system and pressurizing the fuel supply system with a compressed medium via a compressed medium supply to a target pressure. The target pressure is less than a pressure threshold of a check valve that is disposed downstream from the compressed medium supply and upstream from a corresponding combustor of the gas turbine. The method further includes pointing a receiver portion of an ultrasonic detection device proximate to at least one tube fitting of the fuel supply system located between the flow control valve and a combustor which is fluidly coupled to the fuel supply system. Detection of an increase in sound level and/or the sound of popping at the tube fitting is indicative of a leak at the tube fitting.Type: ApplicationFiled: December 14, 2015Publication date: February 23, 2017Inventors: Bouria Faqihi, Abdul Khaliq, James Frederik den Outer, Thomas Earnest Moldenhauer, Michael Lynch, Richard Preston Epley, Steven Castellaw, Sheng Jia Zheng

Publication number: 20050118780Abstract: An improved and new process of fabricating high dielectric constant MIM capacitors. These high dielectric constant MIM capacitor met all of the stringent requirements needed for both for both RF and analog circuit applications. For the high dielectric constant MIM capacitor, the metal is comprised of copper electrodes in a dual damascene process. The dielectric constant versus the total thickness of super lattices is controlled by the number of layers either 4/4, 2/2, and 1/1 artificial layers.
