Abstract: Un débitmètre pour déterminer le débit ou la masse d'un flux mobile de particules fines comprend un système de guidage pour guider la matière à mesurer le long d'une voie prédéterminée comportant une extrémité d'entrée et une extrémité de sortie. Un transducteur est raccordé de manière fonctionnelle à une extrémité du système de guidage; il comprend une colonne mécanique raccordée entre une cellule de mesure et l'extrémité de sortie du système de guidage. La cellule de mesure émet un signal électrique de sortie proportionnel au débit de la matière dans le système de guidage. Un système pour faire vibrer le système de guidage sert à maintenir le mouvement du flux; comme le plan des vibrations est perpendiculaire au plan de mesure, cela élimine les erreurs de mesure dues aux forces de vibration.

Abstract: A fabric flow restriction and method for adjusting the flow resistance throu gh a fabric duct (12, 14, 16, 18 and 20) enables balancing the airflow through a network of fabric ducts. The fabric ducts are air permeable and/or include discharge openings that evenly disperse supply air from within the duct to a room being heated, cooled, ventilated, or otherwise conditioned by the air. Disclosed embodiments include flow restrictions (28, 30 and 32) that are adjustable by tightening a drawstring (90) that constricts an annular web disposed within the duct or inside the duct, or by interchanging fabric mesh es (38) or various flow resistance. In any case, the flow restriction consists of flexible fabric that tends to conform to the changing shape of a fabric duct as the duct alternately inflates and deflates due to changes in air pressure within the duct.

Abstract: L'invention concerne une composition contenant certains colorants avec un décolorant capillaire de catégorie 2 pouvant simultanément éclaircir les cheveux jusqu'à sept niveaux et déposer diverses teintes de couleur en une seule étape. Les colorants sont des dérivés stables au décolorant de colorants azo, triarylméthane, thiazine ou nitro. Lorsqu'ils sont liés au niveau des positions ortho et/ou para par rapport aux centres chromophores et aux groupements auxochromes situés sur ou fixés aux cycles aromatiques de ces colorants, des groupes chimiques de désactivation ou faiblement activateurs améliorent la stabilité des colorants dans le décolorant alcalin. L'absence de substituants désactivateurs ou faiblement activateurs en position ortho et/ou para, ou la présence de groupes fortement activateurs dans ces positions rendent la molécule du colorant susceptible d'une attaque par le décolorant et constituent une probabilité de destruction de ces colorants. Ces groupes chimiques désactivateurs et protecteurs peuvent être des groupes nitro, halogène, cyano, carboxyle, sulfoniques, alkyle ou aromatiques mais pas des groupes amino, hydroxy, alcoxy ou alkylamide.
