Abstract: This invention provides a coated abrasive article (10) comprising a backing (12) bearing on one major surface thereof a layer of abrasive grains (14) overcoated with a loading resistant coating (16) and on the other major surface thereof a layer of pressure-sensitive adhesive (18). The loading resistant coating comprises a lithium salt of a fatty acid. It may also contain additives selected from the group consisting of surfactants, wetting agents, binders, anti-foaming agents, fillers, plasticizers, and mixtures thereof.

Abstract: L'invention concerne un dispositif pour mesurer la pression dans un récipient ou un tuyau (11) comprenant un milieu de pression mélangé avec de la matière solide, un indicateur de pression étant relié au récipient/tuyau au moyen d'une sortie de mesurage (12). Un conduit d'impulsions (14) est adapté de manière à transporter la pression mesurée à la sortie de mesurage vers l'indicateur de pression. Un volume tampon est installé entre ladite sortie et le conduit d'impulsions. Un conduit d'alimentation (16) est relié au volume tampon de manière à envoyer continuellement audit volume tampon un milieu de pression propre, l'écoulement de purge continu étant porté au maximum afin d'assurer la technique de mesurage ou de traitement. L'invention se caractérise en ce que le conduit d'alimentation (16) est conçu de manière à envoyer continuellement au volume tampon un liquide de purge à proximité de l'ouverture du conduit d'impulsions. L'écoulement de purge maximal continu sert à réaliser une contre-pression, ce qui empêche la matière solide d'aboutir au conduit d'impulsions. La création d'une telle contre-pression dans le volume tampon s'effectue par le dimensionnement dudit volume tampon de manière à tenir compte du volume du conduit d'impulsions, de l'écoulement du milieu de pression propre, de l'écoulement de purge, et de l'écoulement maximal d'entrée possible à travers la sortie de mesurage résultant d'une perturbation dans le récipient/tuyau, et de l'écoulement perturbateur, selon la formule volume tampon/volume du conduit d'impulsions = k (écoulement perturbateur/écoulement de purge), où k est un facteur de dimensionnement qui est supposé en prenant en considération le genre et la fréquence des impulsions de pression, et qui varie entre 0,1 et 1.

Abstract: Des ribozymes, des séquences clivant l'ARN, dérivées de séquences présentes dans le virus de l'hépatite delta, ont été manipulés génétiquement pour augmenter la spécificité sans accroître la taille. Les séquences de ribozymes spécifiques sont utiles comme réactifs pour cliver l'ARN pour des études expérimentales ainsi que pour des thérapies antivirales. Des exemples démontrant le ciblage de ces séquences contre HIV et contre la maladie de Crohn sont décrits en détail. Les séquences sont également utiles comme agents diagnostics pour la détection du virus de l'hépatite delta dans des échantillons de tissus et de fluides, ainsi que dans une banque de sang, également pour l'isolement et la caractérisation de nouveaux viroïdes ayant une activité de ribozymes, en utilisant un procédé d'hybridation spécifique à l'ARN. En se basant sur l'analyse de la structure à deux domaines du virus de l'hépatite delta, il est possible de construire un vecteur pour l'expression des protéines du virus de non hépatite delta dans des cellules mammifères.
