| 20090103081 | Calibration of a radiometric optical monitoring system used for fault detection and process monitoring - The present invention is directed to a system and method for radiometric calibration of spectroscopy equipment utilized in fault detection and process monitoring. Initially, a reference spectrograph is calibrated to a local primary standard (a calibrated light source with known spectral intensities and traceable to a reference standard). Other spectrographs are then calibrated from the reference spectrograph rather than the local primary calibration standard. This is accomplished by viewing a light source with both the reference spectrograph and the spectrograph to be calibrated. The output from the spectrograph to be calibrated is compared to the output of the reference spectrograph and then adjusted to match that output. The present calibration process can be performed in two stages, the first with the spectrographs calibrated to the reference spectrograph and then are fine tuned to a narrow band light source at the plasma chamber. Alternatively, the reference spectrograph can be calibrated to the local primary standard while optically coupled to the plasma chamber. There, the local primary standard calibration light source is temporarily positioned within the plasma chamber, or in a light chamber disposed along the interior of the chamber for calibrating the reference spectrograph. Other spectrographs can be calibrated to the reference spectrograph while coupled to the plasma chamber with the local primary standard calibration light source, thereby calibrating every component in the entire optical path to the reference spectrograph. | 04-23-2009 |
| 20100032587 | Electron beam exciter for use in chemical analysis in processing systems - The present invention is directed to a gas line electron beam exciter, gas line electron beam excitation system and method for exciting a gas using an electron beam exciter. The electron beam exciter generally comprises a variable density electron source for generating a cloud of electrons in an electron chamber and a variable energy electron extractor for accelerating electrons from the electron chamber as an electron beam and into an effluent stream for fluorescing species in the effluent. The electron density of the electron beam is variably controlled by adjusting the excitation power applied to the variable density electron source. The electrons in the electron chamber reside at a reference electrical potential of the chamber, typically near ground electrical potential. The electron energy of the electron beam is variably controlled by adjusting an electrical potential across the variable energy electron extractor, which energizes the electrons through an extraction hole of the chamber and toward the extractor. The greater the difference in the electrical potential between the electron extractor and the electron source, the higher the energy imparted to the electrons in the electron beam. The excitation power applied to the electron source can be adjusted independently from the electron energy of the electron beam, thereby altering the electron density of the electron beam without changing the energy level of the electrons of the electron beam. | 02-11-2010 |

| 20110214440 | REFRIGERATING APPARATUS AND METHOD - A refrigerating apparatus having two or more climate controlled compartments is disclosed. The refrigerating apparatus has a climate control device capable of controlling the climate of the compartments. The control device is electrically connected to an interactive display, wherein the display presents a compartment selection element to a user and, upon selection of a compartment by the user, the display presents a predetermined climate control element corresponding to the selected compartment. The compartment selection element comprises a plurality of compartment icons corresponding to the climate controlled compartments of the refrigerating apparatus. The climate control element may comprise, for example, a temperature control icon or a plurality of food-type icons. Preferably, the elements of the display are presented sequentially as the user makes selections. It is also preferred that the user's selections should be highlighted in some manner, for example a color change of the selected icon within an element. | 09-08-2011 |

| 20090155062 | METHOD OF DESIGNING A MULTISTAGE TURBINE FOR A TURBOMACHINE - A method of designing a multistage turbine for a turbomachine in which each turbine stage comprises a stator row and a rotor row each made up of an annular row of airfoils, wherein, for all of the stator or rotor rows, it consists in simultaneously modifying the shapes of the airfoils of said rows to straighten out the wakes from the trailing edges of said airfoils, then in angularly positioning the rows in such a manner that the wakes from the airfoils of the stator (or rotor) airfoils impact against the leading edges of the stator (or rotor, respectively) airfoils of the rows situated downstream, in order to achieve multistage aerodynamic coupling simultaneously over the turbine as a whole. | 06-18-2009 |
| 20110014056 | BLADE WITH NON-AXISYMMETRIC PLATFORM - A blade for a turbomachine impeller including an airfoil and at least one platform at one end of the airfoil, the blade configured to be arranged with a plurality of substantially identical blades so as to form a ring, the platform surface having a suction surface profile and a pressure surface profile respectively along the suction surface and the pressure surface. In the blade, the pressure surface profile including a pressure surface recessed part is located axially in an upstream half of the airfoil. Due to this configuration, efficiency of the blade is improved. | 01-20-2011 |
| 20110110788 | BLADE WITH 3D PLATFORM COMPRISING AN INTER-BLADE BULB - A blade for a turbomachine impeller including an airfoil, and a platform extending at one of the ends of the airfoil in a direction globally perpendicular to a longitudinal direction of the airfoil, the blade configured, together with other identical blades, to form a ring around a ring axis, with the adjacent blade platforms joining in pairs so as to form an inter-airfoil surface linking the pressure surface of one airfoil to the suction surface of the neighboring airfoil. In this blade, the inter-airfoil surface includes, in an upstream half of the airfoil, a boss located closer to the pressure surface than to the suction surface, and a recessed passage located between the same and the suction surface. | 05-12-2011 |
| 20110189023 | BLADE WITH NON-AXISYMMETRIC PLATFORM: RECESS AND BOSS ON THE EXTRADOS - A blade for a turbomachine impeller including an airfoil, and at least one platform at one of the ends of the airfoil, the blade configured to be arranged with a plurality of substantially identical blades so as to form a ring around a ring axis. In the blade, a suction surface profile at the surface of the platform and along the suction surface has a first recessed part located axially in an upstream half of the airfoil and a first boss-like part located axially downstream of the first recessed part. Due to this configuration, efficiency of the blade is improved. | 08-04-2011 |
