Title: Method for regulation of the surface level and the consistency in a tank for metering of a component stock
Inventor: HUHTELIN TAISTO
IPC: D21F1/66
Filed: 1999-06-04
Abstract: A method for regulation of the surface level (L20) and the consistency (C s20) in a stock chest (20) for metering of a component stock (M1). Stock is fed as an outward flow (F11) out of the bottom portion (10a) of a stock column (10) by means of a first pump (11) into the stock chest (20). Into this outward flow (F11) a first dilution water flow (F15) is passed, by means of which dilution water flow the consistency of the stock fed into the stock chest (20) is regulated to the desired level. The stock is fed as a metering flow (F1) from the stock chest (20) by means of a third pump (21) into the short circulation of the paper or board machine. The surface level (L20) in the stock chest (20) is kept invariable by means of an overflow (F13) passed from the stock chest (20) into a pumping tank (20a). From the pumping tank (20a) stock is fed as a return flow (F12), by means of a second pump (12), back into the bottom portion (10a) of the storage tower (10). Into this return flow (F12) a second dilution water flow (F16) is passed, by whose means the consistency in the bottom portion (10a) of the storage tower (10) is regulated to the desired level. The stock (M1) is stirred intensively in the bottom portion (S10) of the storage tower (10) and in the stock chest (20, S20) in order to provide a uniform consistency.

Title: Telephone test set-installed low pass filter circuit for preventing corruption of digital communication signals
Inventor: WONG WAYNE
IPC: H04M1/24
Filed: 2001-04-12
Abstract: Corruption of digital data on a telephone line to which a telephone test set is to be coupled is obviated by inserting a low pass filter circuit in the tip-ring connection path to the test set. The low pass filter provides a low impedance path for only voice band signals, while blocking signals that fall within the high frequency range of digital data.  The low pass filter circuit includes inductors coupled with respective tip and ring leads and a controllably switched, shunt-capacitor circuit coupled across the tip and ring leads. Also, resistors that compensate for impedance variations are coupled in series with the leads and are controllably by-passed, when said telephone test set is to go off-hook.

Title: Ensemble de microphones a haute directivite
Inventor: RUNG MARTIN
IPC: G10L15/28
Filed: 1999-11-12
Abstract: L'invention concerne un ensemble de microphones à haute directivité, qui comprend une multitude de microphones disposés dans un logement allongé (10). Les microphones sont regroupés par paires, les microphones distincts de chaque paire étant placés de chaque côté d'une ligne centrale de l'ensemble de microphones. Les signaux émis par les microphones font l'objet d'une sommation pour former un signal de sortie de l'ensemble de microphones. Les microphones sont situés de chaque côté de la ligne centrale à une distance l'un de l'autre qui n'est pas équidistante ; un filtre passe-bas (F¿1+?, F¿2+?, F¿3+?, F¿4+?, F¿1-?, F¿2-?, F¿3-?, F¿4-?) est placé entre chaque microphone (M¿4-? M¿4+?) et une liaison de sommation (S). les microphones associés à l'une et à la même paire sont connectés à des filtres passe-bas avec la même fréquence de coupure, la fréquence de coupure des filtres de passe-bas étant différente pour chaque paire de microphones. En effet, la fréquence de coupure est plus faible pour la paire de microphones (M¿4-?, M¿4+?) qui se situe le plus loin de la ligne centrale. Plus la paire de microphones se rapproche de la ligne centrale, plus la fréquence de coupure s'élève. L'ensemble de microphones est disposé de telle manière que les distances entre les microphones et les fréquences de coupure des filtres passe-bas soient ajustées les unes par rapport aux autres.

Abstract: Methods for assessing the risk of developing Type 2 diabetes and other related disorders include obtaining an NMR derived reference spectrum for a known glucose concentration sample and storing this information as a reference standard. A patient blood sample is collected and NRM derived patient spectrums for the blood sample are obtained.  The two NMR data sets (the reference and the patient) are compared and a glucose concentration is determined for the patient sample.  The glucose concentration can be evaluated with a blood sample undergoing lipoprotein cholesterol evaluation. The NMR based test can be used to concurrently provide a glucose concentration and lipoprotein constituent values based on a single testing event. The disclosure also includes a multi-purpose test, i.e., a test which concurrently provides lipoprotein screening and coronary heart disease risk evaluation along with a diabetes screening and risk assessment for developing Type 2 diabetes. A method for assessing diabetes includes identifying the presence of diabetic dyslipidemia based on the values of predetermined NMR measured lipoprotein constituents.

Title: Optical attenuator
Inventor: NAKATA HIDENORI
IPC: G02F1/09
Filed: 2000-06-16
Abstract: Disclosed is an optical attenuator capable of increasing its dynamic range and reducing the temperature-dependence of the dynamic range.     The optical attenuator uses a device which applies external magnetic field to a garnet single crystal having a Faraday effect, from two or more directions, to vary the combined magnetic field to thereby control the Faraday rotational angle of passing light, the optical attenuator having a polarizer and an analyzer disposed at the front and rear of the optical axis of the device. Let x be an angle which is formed between the plane of polarization of a single incident light to the garnet single crystal, or the plane of polarization of one of two lights, whose planes of polarization intersect at right angles, and the direction of the magnetic field orthogonal to the optical axis, and let y be an angle which is formed between the polarizer and the analyzer, then the angle x is set to satisfy [(-z/2) + 90 x n] - 12 x [(-z/2) + 90 x n] + 12 (n = 0, 1, 2 or 3), where z y ~ 90; z is the angle of rotation of the plane of polarization caused by the Faraday rotational angle variable device.
