Abstract: L'invention concerne des systemes de distribution d'air et plus particulierement un appareil d'extraction d'air depuis une conduite d'alimentation principale vers une tubulure de derivation. Dans les systemes de distribution d'air conventionnels d'un immeuble, l'air est conduit a partir de la conduite d'alimentation d'air principale vers les diverses gaines de derivation au travers d'ouvertures amenagees dans la paroi de la conduite principale. Dans de telles configurations, le niveau de bruit a l'entree de la gaine de derivation est sensiblement le meme que le niveau de bruit dans la conduite principale. Pour reduire le niveau de bruit, un silencieux est utilise generalement ayant des caracteristiques dimensionnelles tres grandes a la sortie ou l'entree d'une soufflante placee dans la conduite d'alimentation principale, ce qui presente le desavantage evident d'etre couteux, volumineux, et necessitant beaucoup d'espace. Pour eviter ces problemes, un dispositif composite de derivation-silencieux comprend une section de regain de pression statique (SPR) (100) et une section de canal (101) adaptee pour connecter le flux d'air provenant d'une gaine d'entree (102A) sur une gaine de sortie (102B) et au moins une derivation (106, 108). La paroi externe de la section SPR et les parois internes et externes de definition du chemin de la section de canal definissent un canal perimetrique, dont les parois externes ont une section composite caracterisee par une courbe continue, et dont la paroi interne possede une section caracterisee par une courbe continue, les deux courbes continues ayant des composantes de direction radiale.

Abstract: Il est proposé de matérialiser l'élément chauffant d'une sonde détectrice électrochimique par une résistance à coefficient de température positif (PTC) ou de brancher une telle résistance en série avec l'élément chauffant, la sonde étant plongée dans le milieu à mesurer. On obtient ainsi une baisse du rendement du chauffage de l'élément de chauffage de la sonde de mesure lorsque la température du gaz de mesure est élevée. L'endommagement de la sonde par la surchauffe est alors exclue. Comme fil de résistance on peut utiliser du nickel ou des alliages nickel-fer.

Inventor: POST HANS DR
IPC: A61B5/05
Filed: 1983-03-05
Abstract: For the purpose of limiting NMR spectroscopy to a selected area of a body the said area is prepared by applying first a homogeneous magnetic field passing through the entire body and superimposing thereafter upon the said magnetic field a first magnetic field of identical orientation whose strength varies in a first sense (first field gradient), exciting thereafter all the selected nuclear spins present within the body and in addition, selectively, only the nuclear spins present in a first body plane containing the volume element and extending vertically to the said first field gradient so that the selected nuclear spins contained in this body plane are returned to the direction of the homogeneous magnetic field while the nuclear spins outside this plane receive an orientation differing from the sense of the homogeneous magnetic field. This process is repeated twice, using each time a different gradient field, so that thereafter only the nuclear spins located within the volume element selected by means of the three gradient fields are parallel to the homogeneous magnetic field and can be excited by means of one or more pulses to obtain an oscillation generating an induction signal.
