  • Publication number: 20040103662
    Abstract: A system for cooling at least one gas turbine liquid fuel component located in a high temperature environment to eliminate coking in the component is disclosed. The system includes a sleeve surrounding the liquid fuel component, a device for providing a current of cool air, and a conduit connected between the cool air device and the sleeve to direct the current of cool air into the sleeve to cool the liquid fuel component. The system can also include a manifold connected to the conduit and a plurality of second conduits for connecting the manifold to a plurality of sleeves surrounding a plurality of liquid fuel components, each sleeve being connected to a corresponding second conduit. Each sleeve includes a plurality of spacing devices for centering the sleeve around the at least one liquid fuel component so as to form an annulus between the sleeve and the liquid fuel component through which the current of cool air flows.

  • Patent number: 6626635
    Abstract: The clearance control system includes a closed air circuit having a heat exchanger, a circulation compressor and an air heater in series for flowing air heated or cooled to higher and lower system-set discharge temperatures in the casing of rotating machinery to expand or contract the casing, respectively, to maintain optimum clearances between the rotating blade tips and the casing. At start-up, the air heater is energized to supply heated air to and expand the casing. During start-up and subsequent to this initial phase, the air heater is deenergized and the air cooling system is actuated by closing a heat exchanger bypass valve and opening a shutoff valve, enabling the air to be cooled in the heat exchanger. By controlling the flow of coolant to the heat exchanger, the lower set discharge temperature of the air exiting the circulation compressor can be regulated during steady-state operation to maintain the casing contracted for optimal clearance.

  • Patent number: 6438963
    Abstract: A liquid fuel purge system is disclosed for flushing liquid fuel from the combustion chambers of a gas turbine. The liquid purge system includes a three-way valve to pass liquid fuel and, alternatively, purge air to the combustion chambers. The gas turbine may operate on liquid fuel or gaseous fuel. When the turbine is switched to burn gaseous fuel, the liquid fuel remaining in the liquid fuel system is flushed by purge air provided by a liquid fuel purge system.

  • Patent number: 6145318
    Abstract: Compressor discharge air flows through a heat exchanger in heat exchange relation with cooling water and is supplied at reduced temperature in atomizing air and purge modes to combustors in a dual-fuel gas turbine. The heat exchanger has a pair of bypass passages in parallel with a temperature regulating valve controlling flow of water through the heat exchanger in response to the temperature of the compressor discharge air exiting the heat exchanger. Should the flow control valve close in response to low temperature of the compressor discharge air, in the air atomizing mode, the bypass passages with orifices therein provide a minimum protective flow of cooling water to the heat exchanger. In the purge mode where only half the air flow and heat rejection is required in the heat exchanger and the flow control valve closes, a bypass valve in one of the bypass passages closes to enable reduced flow of cooling water through the heat exchanger.

  • Patent number: 6079198
    Abstract: A positive displacement pump supplies a low lubricity liquid fuel through a main supply line to the combustors of a turbine. A pressure transducer and a flow meter are provided in the main fuel supply line. The fuel is supplied to a pressure compensated fuel delivery valve which divides the fuel equally among the combustors and affords pressure compensation. A controller is responsive to the pressure in the main fuel supply line to control a bypass pressure valve to supply fuel in the main supply line at a predetermined pressure. The controller also controls the total volume of fuel flow rate through the pressure compensated fuel delivery valve responsive to the flow meter. In another form, a centrifugal pump supplies fuel to the pressure compensated fuel delivery valve. A controller responsive to the flow meter in the main supply line controls the total fuel flow rate to the valve which divides the fuel equally among the combustors at equal flow rates.

  • Patent number: 4902079
    Abstract: A data entry terminal includes a front panel, a shroud and a base plate. The terminal may be assembled as a desk mounted unit or a wall mounted unit, depending upon the orientation of the front panel to the shroud and base plate.

  • Patent number: 4903230
    Abstract: In a computer terminal an electronic device allows the selection of the terminal address and baud rate via a DIP switch (Dual In-Line Package) located internally in the terminal or via external selection means by allowing the setting of signal line voltage level by means of jumper wires in a communication connector. To enable the external option, predetermined pins in the communications connector are jumpered to disable the DIP switch, whose settings are then ignored. By jumpering other predetermined pins in the communications connector, the signal line levels define the terminal address and the terminal baud rate.

  • Patent number: 4727934
    Abstract: A data entry terminal for use in a hostile environment is sealed from the outside environment. The terminal has a housing made up of a front panel, shroud and base plate that are fastened together in two different orientations to facilitate desk top and wall mounting, and electronic equipment is mounted inside the terminal enclosure. A fan circulates air around the inside of the terminal enclosure for cooling the electronic equipment inside. The enclosure base acts as a heat sink to transfer the heat to the outside environment in whatever position the terminal is mounted.

  • Patent number: 4558839
    Abstract: A mounting bracket system mounts a factory data collection terminal vertically to a wall to secure the terminal rigidly to the wall surface and also to permit a quick disconnect of the terminal. This is accomplished by fastening two brackets with keyhole slots which are attached to the upper area of the terminal and using two spring loaded captive fasteners which are accessible from the front of the terminal and attached to the bottom of the terminal.

  • Patent number: 4112926
    Abstract: A method of measuring hyperactivity includes determining the total number of movements of the subject as well as the number of movements which occur at a rate exceeding a preselected threshold. When the rate exceeds the threshold, biofeedback conditioning may be employed to alert the patient in order to condition him against such activity. An apparatus employing the method includes a counting unit worn on the belt of the subject. The counting unit records movement detected by a set of mercury switches. The total number of times a mercury switch is opened is counted as well as the number of times the rate threshold is exceeded. This information is stored in the counters for subsequent evaluation. An oscillator circuit gated by the counting unit provides an audible signal to the subject when the rate threshold is exceeded. A readout and display circuit is utilized for obtaining the information stored in the counting unit.
