Non-Iterative Method For Obtaining Mass Flow Rate

View page
US Patent:
6352001, Mar 5, 2002
Filed:
Aug 30, 1999
Appl. No.:
09/385572
Inventors:
Thomas Edward Wickert - Clifton Park NY
Ravi Rajamani - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01F 137
US Classification:
7386152
Abstract:
The present invention provides a method for calculating flow rate of a fluid using a pressure differential device, based on detected pressure and temperature upstream of and detected pressure adjacent a flow constriction of the pressure differential device, and calibration coefficients calculated from the results of a flow calibration performed on the pressure differential device. By incorporating the results of the flow calibration in the computation, a non-iterative method for obtaining mass flow rate is realized.

On-Line Color Measurement System For Cooled Product

View page
US Patent:
6469789, Oct 22, 2002
Filed:
Aug 22, 2000
Appl. No.:
09/643245
Inventors:
Ravi Rajamani - Schenectady NY
Vijay Kumar Mallikarjun Hanagandi - Evansville IN
Assignee:
General Electric Company - Niskayuna NY
International Classification:
G01J 350
US Classification:
356402, 250226, 356425
Abstract:
An on-line color sensor supplies light to a spectrophotometer for color measurement of product after cooling. The product is extruded in a main extruder having a bypass section. The on-line color sensor includes an housing having an interior portion. The housing is positioned proximate to the bypass section and is used to direct the product from the bypass section into the interior portion. A receptacle that is connected to the housing is positioned in the interior portion of the housing to hold the product directed into the interior portion. The product is allowed to cool while being held on the receptacle. A light source is connected to the housing and supplies light to the interior portion of the housing. A light receiver is connected to the housing to capture the light from the light source in the interior portion that is affected by the cooled product. The captured light is supplied to the spectrophotometer to measuring the color of the cooled product in the interior portion of the housing.

Model-Based Detection Of Leaks And Blockages In Fluid Handling Systems

View page
US Patent:
6526358, Feb 25, 2003
Filed:
Sep 25, 2000
Appl. No.:
09/669231
Inventors:
Anju Narendra - Beaverton OR
Ravi Rajamani - West Hartford CT
Bruce G. Norman - Charlton NY
John Harry Down - Lanesboro MA
Sal A. Leone - Glenville NY
Jonathan Carl Thatcher - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01F 100
US Classification:
702 51, 702 45, 702 50
Abstract:
A fault detection and isolation system for detecting leaks and blockages in a fluid handling system having at least one component through which fluid flows includes sensors for measuring fluid conditions upstream and downstream of the component. The sensors generate signals that are representative of the upstream and downstream fluid conditions and are fed to a control algorithm. The control algorithm uses the measured fluid conditions to generate estimates of an inlet state for the component and an outlet state for the component. The control algorithm also calculates innovation sequences for the estimated inlet and outlet states, and then compares the innovation sequences to predetermined thresholds to detect leaks and blockages.

On-Line System For Measuring Properties Of A Product

View page
US Patent:
6678052, Jan 13, 2004
Filed:
Oct 3, 2000
Appl. No.:
09/677612
Inventors:
Mark Erik Nelson - Mt. Vernon IN
Ravi Rajamani - West Hartford CT
Assignee:
General Electric Company - Niskayuna NY
International Classification:
G01N 2159
US Classification:
356440, 356410, 356436
Abstract:
An on-line sensor is provided that supplies light to a spectrophotometer to measure the color a product extruded through a conduit having a bypass section. The on-line sensor includes a transparent member with an opaque outer surface and an interior portion extending from a first end to a second end to the transparent member. The interior portion is connected to the bypass section, and the product that flows through the bypass section is supplied to the interior section of the transparent member. A light source connected to the transparent member and provides light to the transparent member inside the opaque outer surface. A light receiver is connected to the transparent member and captures light from the light source in the transparent member that is affected by the product. The captured light is supplied to the spectrophotometer to at least measure the properties of the product supplied to the interior portion of the transparent member.

Gas Turbine System Operation Based On Estimated Stress

View page
US Patent:
6694742, Feb 24, 2004
Filed:
Jun 26, 2002
Appl. No.:
10/179277
Inventors:
Ravi Rajamani - West Hartford CT
David Allen Flodman - Rowley MA
Robert Scott Garry - Delmar NY
Bruce Gordon Norman - Charlton NY
Leroy Tomlinson - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
F02C 100
US Classification:
60772, 60 39281
Abstract:
Critical stress in a gas turbine can be estimated using one or more readily measurable temperatures in the gas turbine. First and second critical temperatures can be estimated based on the at least one measurable temperature using heat conduction and convection equations. Subsequently, the critical stress can be estimated in real time according to a stress model prediction based on the difference between the critical temperatures, and possibly the rotational speed of the turbine, and some parameter, such as air pressure, that is indicative of air flow around the turbine component. Operation of the gas turbine can thus be controlled using the estimated critical temperatures.

Method And Apparatus For Reduction Of Combustor Dynamic Pressure During Operation Of Gas Turbine Engines

View page
US Patent:
6973791, Dec 13, 2005
Filed:
Dec 30, 2003
Appl. No.:
10/748360
Inventors:
Steven Keith Handelsman - Cincinnati OH, US
Michael Richard Durling - Fort Edward NY, US
James David Rackmales - Hardy VA, US
Mark Stephen Lipton - Mason OH, US
William Lee Barrow - Kings Mills OH, US
Robert John Pearson - Middletown OH, US
Ravi Rajamani - West Hartford CT, US
Assignee:
General Electric Company - Schenectday NY
International Classification:
F02C009/00
US Classification:
60773, 60725, 60 39281
Abstract:
Methods and apparatus for operating a gas turbine engine without sustained detrimental levels of dynamic pressure are provided. The engine includes a combustor. The method includes determining the combustor acoustic level amplitude, comparing the acoustic level to a predetermined upper acoustic limit, and adjusting a fuel flow distribution to the combustor using a closed loop controller to facilitate reducing the acoustic level to a predetermined lower acoustic limit that is less than the upper acoustic limit.

Rotable Inventory Calculation Method

View page
US Patent:
7647255, Jan 12, 2010
Filed:
Jan 23, 2004
Appl. No.:
10/763803
Inventors:
Jihua Wang - Unionville CT, US
Ravi Rajamani - West Hartford CT, US
Robert Tomastik - Rocky Hill CT, US
Thomas Gannon - East Hampton CT, US
Assignee:
United Technologies Corporation - Hartford CT
International Classification:
G06Q 10/00
US Classification:
705 28, 705 8
Abstract:
A method for conducting a repairable inventory analysis calculates the minimum number of repairable parts to be held in inventory while still being able to satisfy the demand for spare parts even in view of uncertain repair lead times. The method uses a set of equations that relates a customer service level to arbitrary probability distribution functions of a repair lead-time and a part arrival process. The distributions are then searched to locate the optimal inventory level in the distribution.
