Abstract: L'invention a pour objet un appareil destiné à purifier l'air, notamment l'air pollué de fumées plus ou moins épaisses. Cet appareil comprend un réservoir cylindrique allongé contenant une petite quantité de liquide non volatil, tel que de l'eau, et à l'intérieur duquel tourne une vis sans-fin réalisée en un matériau grillagé ou en un matériau plein perçé de nombreuses perforations. Un jeu de conduites d'air reliées à un ventilateur, sert à faire circuler l'air pollué à l'intérieur du réservoir cylindrique dans lequel  la vis sans-fin brasse en permanence le liquide non volatil, et à recueillir l'air ainsi débarrassé de ses fumées. Cet appareil peut être avantageusement utilisé dans des endroits comme des départements à soudure, des salles de conférence ou tout autre endroit où l'air est, ou peut être, notablement pollué par des fumées.

Abstract: ABSTRACT OF THE DISCLOSURE           A non-impact printer having a support for magnetic ink particles loosely distributed on its surface in mutually spaced aggregates of irregular height.  An electrical field of short duration, established in a print position between the particles and a shaped print electrode, charges the particles and attracts them to an intervening recipient sheet.  The printed image is rendered more uniform by magnetic reorientation of the aggregates of greater height before printing, in a field having components normal to the electrical field in the region of the print position.

On met d'abord en état d'alerte cette ligne de transducteurs à l'approche d'un iceberg; on commande alors à intervalles réguliers l'émission de signaux acoustiques à partir de l'organe d'émission, certains de ces signaux étant réfléchis par la partie immergée de l'iceberg et atteignant les récepteurs acoustiques; on détecte les signaux réfléchis, on détermine leurs temps de transit entre l'organe d'émission et certains au moins des récepteurs de la ligne, situés de part et d'autre dudit organe d'émission, et on en déduit les distances correspondantes parcourues par les signaux acoustiques connaissant leur vitesse de propagation dans l'eau.  On répète ensuite les étapes de commande et de détection et on détermine un ensemble de valeurs comprenant la valeur minimale des temps de transit, pour un même signal émis, correspondant sensiblement au passage du point le plus bas de l'iceberg dans un plan vertical.  On déduit enfin de l'ensemble de valeurs minimales des temps de transit, la configuration géométrique de la partie immergée de l'iceberg en section par le plan vertical, ainsi que le tirant d'eau de l'iceberg.

Abstract: PULP SHEET FORMING DEVICE                 ABSTRACT OF THE DISCLOSURE      A high consistency pulp slurry is prevented from floccing by at least one pivotable member located in the vat at the area where the pulp slurry leaves the inlet box and enters the vat.  The pivotable member is located with respect to the inner surface of the vat and is structured to speed-up-the pulp slurry as it enters the vat to prevent floc formations.    If pulp fibers should become stuck in the small space between the outer surface of the pivotable member and the inner surface of the vat, the pivotable member will automati-cally pivot away from the inner surface of the vat, thereby automatically loosening the stuck fibers.  As soon as the stuck fibers are loosened, the pivotable member will return to its initial position.

Abstract: Abstract of the Invention A welded wire mesh strip employed to reinforce a concrete pipe coating has its longitudinal wires deformed to an extent that increases progressively across the strip. The coating is applied to the pipe by rotation of the pipe while moving it past a concrete spraying station and simultaneously winding the reinforcing strip onto the concrete to become embedded therein.  The non-uniform deformation of the longitudinal wires enables the strip to accomodate to the frustoconical shape that the exposed concrete temporarily assumes at the spraying station.

Granted: 1982-06-08
Abstract: U.S. 904,826 ABSTRACT OF THE DISCLOSURE          An increased yield of hydrogenated liquid product is obtained from coal by contacting the feed coal with a hydrogen-donor solvent and a hydrogen-containing gas in a series of two or more liquefaction zones arranged in series and operated in such a manner that the temperature in each zone increases from the initial to the final zone.  The effluent from each liquefaction zone is passed to the next succeeding higher temperature zone in the series.  Liquid hydrocarbonaceous products are recovered from the effluent with-drawn from the last zone.  Hydrogen-donor solvent may be produced in the process by catalytically hydrogenating at least a portion of the liquid product from the last liquefaction zone, recovering a liquid fraction from the product of the catalytic hydrogenation and separating a hydrogen-donor solvent from the liquid fraction.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to apparatus for tracking the peak of a correlation function between two signals.          A first correlator is responsive to the signals and provides a coarse measure of the position of the peak.  A second correlator is also responsive to the signals and tracks the position of the peak when the coarse measure corresponds to the tracking range of the second correlator.  The first correlator is connected to the second correlator for causing the tracking range thereof to correspond to the coarse measure.  The apparatus finds particular use as a flowmeter in which flow velocity is deter-mined by identifying the time delay between the two signals.          If the distance between the points of derivation of the two signals is constant, the flow velocity is inversely proport-ional to the identified time delay.
