Title: Introduction de mousse sans fibres dans la caisse de tete ou a proximite de celle-ci pendant un procede de fabrication de papier a la mousse
Inventor: JANSSON JUHANI
IPC: D21F11/00
Filed: 1998-09-03
Granted: 2006-12-12
Abstract: Dans un procédé de fabrication à la mousse servant à fabriquer une bande de non-tissé en matériau fibreux (tel qu'un matériau en fibres synthétiques ou cellulosiques), on introduit de la mousse sensiblement exempte de fibres à différents emplacements d'une caisse de tête, ou en position contiguë à cette dernière, afin de produire des résultats améliorés. L'introduction de mousse pure dans le mélange constitué par de la mousse et des fibres à proximité (par exemple, immédiatement avant) du point d'introduction dudit mélange dans la caisse de tête, permet d'atteindre un profil plus uniforme du poids de base de la bande de non-tissé fabriquée (par exemple, une variation du poids de base égale ou inférieure à 0,5%). L'introduction d'une autre quantité de mousse sensiblement exempte de fibres dans la caisse de tête au niveau d'une surface située à distance de l'élément foraminé, afin que ladite quantité s'écoule le long de la surface (normalement parallèle à l'écoulement du mélange de fibres et de mousse), permet de limiter le cisaillement des fibres dans la caisse de tête, de sorte que les fibres ne se trouvent pas dirigées dans un seul sens, au sens de déplacement de l'élément foraminé et de conserver la propreté de la surface. Cette surface se présente sous la forme de la couverture d'une caisse de tête inclinée.

Title: Process and apparatus for electrocoagulative treatment of industrial waste water
Inventor: PETRU JONATHAN M
IPC: C02F1/52
Filed: 1998-11-23
Granted: 2003-08-19
Abstract: An electrocoagulation system for removing contaminants from waste effluents comprising an electrocoagulation reactor (140) having charged and uncharged plates and allowing serial flow of water therethrough. The reactor (140) is connected to a voltage source (160) to charge some of the plates positive and negative plates. The system allows waste water to enter the reactor (140) for coagulation therein, the waste water leaving the reactor (140) to enter a defoam tank (200) for agitation which allows trapped bubbles to rise to the surface of the tank (200) as foam. From the defoam tank (200), waste water goes through a sludge thickener, to allow sludge to settle at the bottom thereof and waste water is drawn off from the sludge thickener to flow to a clarifier (250). The pump removes sludge forming at the bottom of clarifier (250) to take it back to the sludge thickener. The sludge is drawn out the bottom of the sludge thickener for transport to a press (280) where most of the water is removed therefrom. Water is drawn off the top of the clarifier (250) for transport to a conventional sewer system, or for reuse.

Abstract: Both an apparatus and method are provided for electromagnetically braking a flow of molten metal during a continuous casting operation. The apparatus includes an electric electromagnetic inductor of the traveling-magnetic-field polyphase stator-type connected to a source of electrical power. The inductor is mounted on a casting plant opposite one face of the product being cast, and has two or three phase windings. The electrical power supply of the apparatus includes two or three elementary DC sources, each of which can be adjusted in terms of current intensity independent of one another. Each of the elementary electrical DC sources is connected to one, and only one of the phase windings of the inductor. The arrangement of the apparatus allows a flow of molten, ferromagnetic metal such as steel to be adjustably braked by merely adjusting the parameters of the source of electrical supply.

Abstract: An in line feed method and apparatus for forming slugs of incoming items, which are standing on edge and aligned front-to-back is disclosed. The process uses a conveyor belt and a vacuum chamber aligned end to end for separating the flow of items and creating slugs. The items introduced to the system are on a conveyor belt. The belt is periodically stopped and the items blocked from being sucked into the vacuum chamber. While the product is blocked from entering the vacuum chamber a moving finger which travels through the chamber is introduced at the mouth of the vacuum chamber and the items are released from the conveyor belt such that they are sucked into the vacuum chamber but are limited by and stack up against the finger. In this manner slugs are formed.

Title: Calibrated measurement of blood vessels and endothelium after reactive hyperemia and method therefor
Inventor: RAINES JEFFREY K
IPC: A61B5/022
Filed: 2000-03-24
Granted: 2003-02-18
Abstract: The calibrated method for characterizing blood flow in a limb of a patient during reactive hyperemia utilizes a blood pressure cuff (14). The method establishes a predetermined, near diastolic, pressure in the blood pressure cuff (14) during the reactive hyperemic episode, continually senses via a sensor (68) the pressure in the cuff, and periodically changes the internal volume of the blood pressure cuff by a predetermined volumetric amount to calibrate the system. The resultant change in the pressure is a calibration pressure pulse (P-cal), and is used to calculate pulsatile blood volume through the blood vessel. A calibrated method for determining the condition of blood vessels, and endothelium includes determining, for each calibration cycle, a respective peak value (t-P) for the blood volume, and comparing the peak blood volume values with peak blood volume values for healthy blood vessels, and endothelium. The comparison preferably utlizes a waveform (W1).
