20100231598 | Serving Font Glyphs - A computer-implemented method for obtaining a font for a document includes determining each glyph of a font that is specified in contents of an electronic document, the determination identifying a subset of multiple glyphs included in the font, the subset determined on a first device that does not have the font stored thereon. The method includes generating on the first device a request to a second device based on the determination, the request identifying the subset to the second device. The method includes receiving, at the first device, information sent from the second device in response to the request and defining the subset of the multiple glyphs, the information not defining a remainder of the multiple glyphs other than the subset. The method includes generating on the first device a presentation of the electronic document using the received information, the presentation including the subset of the multiple glyphs. | 09-16-2010 |

20090025389 | Turbine Systems and Methods for Using Internal Leakage Flow for Cooling - A cooling system for a turbine with a first section and a second section. The first section may include a first line for diverting a first flow with a first temperature from the first section, a second line for diverting a second flow with a second temperature less than the first temperature from the first section, and a merged line for directing a merged flow of the first flow and the second flow to the second section. | 01-29-2009 |
20090238679 | STEAM TURBINE AND A METHOD OF DETERMINING LEAKAGE WITHIN A STEAM TURBINE - A steam turbine includes a shaft operatively connecting a first turbine section and a second turbine section. A packing assembly is positioned about the shaft. A first conduit is fluidly connected to the packing assembly. The first conduit is configured to introduce a flow of low temperature, low pressure steam to the packing assembly. A second conduit is also fluidly connected to the packing assembly downstream from the first turbine section and upstream from the first conduit. The second conduit receives a portion of the high temperature, high pressure steam passing into the packing assembly from the first turbine section. A valve is fluidly connected to the second conduit. The valve is configured to be selectively operated so as to allow the high temperature, high pressure steam to mix with the low pressure, low temperature steam in the second conduit. | 09-24-2009 |
20090257878 | LOW EXHAUST LOSS TURBINE AND METHOD OF MINIMIZING EXHAUST LOSSES - Disclosed herein is a method of minimizing losses in a multiple-last-stage bucket turbine. The method includes, determining an inlet flow available for the multiple-last-stage bucket turbine, and selecting multiple last-stage buckets from a set of pre-designed last-stage buckets. The multiple last-stage buckets having inlet flows different from one another that when combined match the inlet flow available with a lower total exhaust loss than from multiple same sized last-stage buckets from the set of pre-designed last-stage buckets. | 10-15-2009 |
20090285670 | APPARATUS AND METHOD FOR DOUBLE FLOW TURBINE FIRST STAGE COOLING - A method of cooling a double flow steam turbine includes supplying steam flow to each nozzle of the sections of the turbine; reversing a portion of each steam flow to provide a reverse steam flow from an aft side to a forward side of each section. Each reverse steam flow is directed to an annular space between a rotor and a tub. The method further includes removing the reverse steam flows through a pipe, the pipe having a first end at the annular space at a first pressure and a second end at a second pressure that is lower than the first pressure. A double flow steam turbine, includes a pair of nozzles, each nozzle being provided at a section of the turbine; a rotor supporting buckets of the sections; a tub supporting the pair of nozzles; and a pipe extending from an annular space between the tub and the rotor. The pipe has a first end at the annular space and second end. A pressure at the first end of the pipe is greater than a pressure at the second end. | 11-19-2009 |
20100158666 | OPPOSED FLOW HIGH PRESSURE-LOW PRESSURE STEAM TURBINE - An opposed flow high pressure-low pressure steam turbine balances thrust of the high pressure steam turbine with the thrust of the low pressure steam turbine allowing a reduction in size of thrust bearings. Higher stage reactions in both turbines may be incorporated since they are offset with the opposed flow, allowing a higher steam path efficiency. Opposed flow may be established through a cross-over pipe or utilizing a double high pressure shell. | 06-24-2010 |
20100175378 | Method and apparatus for varying flow source to aid in windage heating issue at FSNL - A method and apparatus are disclosed for alleviating the problem of windage heating when flow, in a turbine running at full speed, no load, decreases greatly at the exhaust of the high pressure sections of the turbine. Valves connecting the different pressure levels of a heat recovery steam generator to the input of the turbine are adjusted to mix steam coming from the different pressure levels to create desired steam conditions at the inlet and the exhaust output of the turbine that allow the use of existing steam path hardware and thereby reduce the cost of such piping. In an alternative embodiment for a single pressure HRSG, high pressure saturated steam is extracted from the HSRG evaporator and then flashed into superheated steam when passing thru a control valve, that is then used to create the desired steam conditions at the inlet and the exhaust output of the turbine. | 07-15-2010 |
20100178156 | STEAM TURBINE HAVING EXHAUST ENTHALPIC CONDITION CONTROL AND RELATED METHOD - A steam turbine includes a casing including a steam inlet and an exhaust, the casing enclosing operative structure of the steam turbine; a valve controlling introduction of a steam flow at a location of the steam turbine to impact an enthalpic condition of steam exiting the exhaust; and a controller controlling operation of the valve to attain a desired enthalpic condition of steam exiting the exhaust. Controlling operation of the valve allows for attainment of a desired enthalpic condition of the steam exiting the exhaust for use in another industrial process without having to modify the steam turbine structure. | 07-15-2010 |
