Title: A method of calibrating a spectrometer using correlation between calibration sample spectra and measured spectra
Inventor: GETHNER JON S
IPC: G01N21/35
Filed: 1991-10-09
Abstract: A method of operating a spectrometer to determine property (13) and/or composition data of a sample comprises an on-line spectral measurement (1) of the sample using a computer controlled spectrometer, statistical analysis of the sample data based upon a statistical mode (2, 3, 4) using ample calibration data, and automatically, identifying a sample if necessary based upon statistical and expert system (rule-based) criteria.     Sample collection based upon statistical criteria consists of performing a statistical or rule-based check against the model to identify measurement data which are indicative of chemical species not in the samples already stored in the model. Samples identified either by a statistical criteria or using an expert system (rule-based decisions) are used preferably to isolate the liquid sample using a computer controlled automatic sampling system.      The samples can by saved for subsequent laboratory analysis in removable sample containers. The results of the laboratory analysis together with the on-line spectroscopic measurements are preferably used to update the model being used for the analysis.

Title: Methode et appareil de suppression de bruits a spectre etale
Inventor: BRUCKERT EUGENE J
IPC: H04B1/7107
Filed: 1993-06-14
Abstract: L'invention concerne un dispositif de suppression (182) du bruit d'étalement du spectre. Ce dispositif consiste à déterminer une phase reçue et une amplitude reçue pour une première (216) et une seconde (236) composante d'un signal (200) à étalement du spectre reçu. La seconde composante (236) présente une structure similaire à celle de la première composante (216), mais elle est différente dans le sens où elle est reçue à un moment différent, où elle est transmise le long d'une voie différente et où elle possède une phase différente. De plus, le signal (200) à etalement du spectre comprend un premier et un second signal connus. On supprime une partie du signal du bruit d'étalement du spectre dans le signal reçu (200) en générant un signal estimé (270) par étalement (260) du second signal connu au niveau de la phase reçue de la seconde composante (224) avec le premier signal connu au niveau de la phase reçue de la première composante (204) et en réglant le gain (268) d'une forme intégrée du second signal connu étalé en fonction des amplitudes reçues des première (216) et seconde (236) composantes. Par la suite, on traite le signal à étalement du spectre reçu (200) pour en extraire le second signal connu en soustrayant (166) le signal estimé (270) d'une forme démodulée (216, 236) du signal à étalement de spectre reçu (200).

Title: Diaphragm valve
Inventor: ITOI SHIGERU
IPC: F16K7/16
Filed: 1994-05-31
Abstract: A diaphragm valve is disclosed in which a diaphragm is movable to engage or disengage from a valve seat in a replaceable seat ring to restrict or permit fluid flow.  The seat ring includes a valve hole for communicating with a valve flow-in passage mouth and a communication hole for communicating with a valve flow-out passage mouth.  The annular valve seat is provided projecting from the surface of the seat ring, formed along the peripheral edge of the valve hole.  On a back side face of the seat ring spaced from the diaphragm, a seal part is formed projecting along the peripheral edge of the valve hole and a ring contact part is formed projecting along the peripheral edge of the valve ring.  The projection of the seal part from the ring back side is set slightly larger than that of the ring contact part such that when the ring contact part is brought into contact with a bottom wall of the valve under compressional forces, the valve ring is bent elastically, and hence the contact surface pressure of the seat part to the valve bottom is increased.  The increased contact surface pressure preventing fluid from leaking out between the flow-in passage mouth opening in the bottom surface of the valve and the seat ring.

A center sill assembly (16) has first and second spaced apart side plates (18, 20) spaced to either side of the longitudinal centerline of the car body.  A top plate (28) extends along the center sill assembly, the width of the top plate corresponding to the width between the side plates.  The top plate is attached to the side plates to form part of the center sill assembly.  A weld support (50) is installed on both sides of the assembly.  Part of the respective side plates and top plate are cut-away at the junction formed between to form a pocket (56) in which welding material pools.  Weld support members (52, 54) are attached to the top plate adjacent the pockets.          The weld supports provide a substantial contact surface between the center sill assembly and the cradle pad.  Each weld support helps dam the pooled welding material so it is available to effect a strong and durable weld between the cradle pad and center sill assembly.  This allows the tank car to carry heavier loads than could previously be carried.

Title: Analyzing an image showing a graphical representation of a layout
Inventor: MAHONEY JAMES V
IPC: G06V30/40
Filed: 1994-10-03
Abstract: Input image data define an input image set that shows a graphical representation of a layout with two or more segments. The graphical representation can be a sketch, and can include, for example, a rectangular boundary with lines parallel to its sides defining rectangular segments within the boundary. The input image data are used to obtain segment source data indicating a source for each segment and segment position data indicating a position for each segment. The segment source data can indicate, for each segment of the layout, one of a number of source images in the input image set. The segment position data can indicate a reference point and a width and height for each segment. The source image for a segment can be a sketch of a graphical representation-such as a node-link structure, a parallel length graph, a proportioned parts graph, a row/column representation, a perimeter relationship representation, or a two-dimensional graph-that can be categorized and rendered to obtain data defining a precisely formed graphical representation. The segment source data for other segments and the segment position data can be used with the data defining the precisely formed graphical representation to obtain output image data defining an output image that includes a layout as represented by the graphical representation.
