  • Patent number: 6907738
    Abstract: A pilot air system for a combustor of a gas turbine including: a pilot air compressor having inlet connectable to in to a main passageway, wherein the main passageway receives compressed air from a compressor for the gas turbine; a pilot air platform positioned adjacent to the combustor of the gas turbine, wherein the pilot air compressor is positioned on the platform; an inline throttling valve coupled to the first main passageway; a by-pass passageway for the pilot air, proximate to the platform, and arranged in parallel to the main passageway and compressor, wherein the by-pass passageway receives pilot air from the main passageway downstream of the pilot air compressor and passes a portion of the compressed pilot air to the main passageway upstream of the pilot air compressor; a by-pass throttling valve inline with the by-pass passageway to meter pilot air flowing through the by-pass passageway, and the main passageway having an outlet connectable to the combustor.

  • Patent number: 6901761
    Abstract: A pilot air system for providing pilot air to a combustor of a gas turbine wherein the system includes: an inlet to receive a portion of compressed air discharged by a compressor of the gas turbine, wherein the portion of the compressed air is pilot air; a main passageway coupled to the inlet and providing a passage for the pilot air; an inline throttling valve coupled to the main passageway and metering a pressure of the compressed air in the main passageway; a pilot air compressor in series with the main passageway; a by-pass passageway for the pilot air and arranged in parallel to the main passageway and compressor, wherein the by-pass passageway receives pilot air from the main passageway downstream of the compressor and passes a portion of the compressed pilot air to the main passageway upstream of the compressor; a by-pass throttling valve inline with the by-pass passageway to meter pilot air flowing through said by-pass passageway, and the main passageway is connectable to the combustor.

  • Publication number: 20050031259
    Abstract: An apparatus for monitoring an input optical signal at a plurality of distinct optical frequencies is disclosed wherein a demultiplexing arrayed waveguide grating (AWG) having a plurality of M>1 Vernier input ports is disposed between an optical switch and a photodiode array coupled to the output ports of the AWG. In operation, the optical switch sequentially provides the input optical signal into each of the Vernier ports, and signals detected by photodiodes are stored in a memory unit. The apparatus is capable of monitoring the input optical signal with a frequency step which is M times smaller than a frequency spacing between the AWG transmission bands, and obtain M frequency-resolved readings from each photodiode.

  • Patent number: 4961159
    Abstract: A cellular automaton which generates pseudorandom data comprises a series of cells arranged such that each cell receives signals from electrically adjacent first and second cells. Each cell comprises a D-type flip-flop for storing a data bit, and logic circuitry which couples the flip-flop of the cell to those of associated first and second adjacent cells. The logic circuitry responds to the current state of the data bits stored by a particular cell and its associated first and second electrically adjacent cells by changing the value of the data bit stored by the particular cell according to a predetermined one of the following relationships:a(t+1)=a .sub.first (t) XOR a.sub.second (t), ora(t+1)=a .sub.first (t) XOR a(t) XOR a.sub.second (t)where, a(t) represents the current state of the data bit stored by the particular cell, a(t+1) represents the next state of the data bit stored by the particular cell, a.sub.
