    摘要: An improved motionless mixer, referred to herein as an acceleration valve, for dissolving gases in liquids is disclosed. The valve incorporates a helical mixing element (1) in which the pitch of the blade or vane of the helical mixing element (1) decreases continuously along the length of the mixing element (1). The linear velocity of the flowing liquid is thereby subjected to increasing angular acceleration resulting in centrifugal force against the retaining walls (3). This additional pressure generated on the liquid increases the amount of gas that may be dissolved in the liquid.

    摘要: In a process for the generation of a cold gas comprising introducing a relatively warm gas and a liquid cryogen into the upstream end of a mixing zone: permitting the gas and liquid cryogen to mix in the mixing zone, the amount of gas being sufficientto vaporize the liquid cryogen; and withdrawing the cold gas downstream in the mixing zone, the improvement comprising:
    (a) choking the gas prior to its entry into the mixing zone: (b) providing a linear mixing zone having, at its downstream end, a dead end; and (c) withdrawing the cold gas as a slipstream from the mixing zone at a point intermediate between its upstream end and the dead end
    provided that the distance from the upstream end to the dead end is at least twice the distance from the upstream end to the point of withdrawal of the slipstream.

    摘要: Die Erfindung betrifft ein Verfahren zur biologischen Rei nigung von organische Schmutzstoffe enthaltenden Flüssig keiten und/oder Flüssigkeits-Feststoffgemischen sowie eine Vorrichtung zur Durchführung des Verfahrens. Die zu behan delnden Flüssigkeiten und/oder Flüssigkeits-Feststoffgemi sche werden dabei durch einen Reaktor geleitet, in dem die Schmutzstoffe mit Hilfe von auf mindestens einem Trägerele ment angesiedelten Mikroorganismen gegebenenfalls unter Zufuhr von Sauerstoff und/oder Sauerstoff enthaltenden Ga sen abgebaut werden. Um auf einfache Weise unter Einhaltung geringer Investitions- und Betriebskosten einen möglichst ho hen Wirkungsgrad zu erreichen, wird mit Hilfe des Trägerele ments in der Strömung eine vollständige statische Durchmi schung im Mikrobereich erzeugt.

    摘要: There is provided a method and apparatus for delivering a substantially constant ratio of two gases to an air intake where a varying suction exists. One gas is passed through an inlet port (10) of a body to the inlet end of a passageway in a rotary valve (80) captured within a suitable chamber (73) in the body, thence to the outlet end of the passageway, thence through an outlet portion (69), thence to the air intake. The other gas is passed to a first tube (95) extending along the axis of the rotary valve within the passageway, with a second tube (97) closely enveloping the first. One tube rotates with the rotary valve, the other is fixed. Both tubes have apertures which are in registry when the rotary valve is oriented such that the passageway communicates with both ports. The angular orientation of the rotary valve is adjusted in such a way as to maintain a substantially constant pressure drop between two points respectively upstream and downstream of the rotary valve.

    摘要: Die Vorrichtung dient zur Be- und Verarbeitung unter schiedlichster Stoffe, beispielsweise zum Homogenisieren, Vordosieren, Plastifizieren oder Mischen. In einem Arbeits raum (5) der Vorrichtung ist ein drehbar angetriebenes Bearbeitungswerkzeug (2) untergebracht, das die Stoffe während der Bearbeitung einem Gehäuseauslaß (6) zuführt. Der Arbeitsraum (5) hat einen in Richtung auf den Auslaß (6) im Querschnitt sich verjüngenden Förderabschnitt (7), der in Förderrichtung (8) der Stoffe in einen Bearbeitungs abschnitt (9) des Arbeitsraumes (5) übergeht. Der Bearbei tungsabschnitt (9) verjüngt sich im Querschnitt ebenfalls in Richtung auf den Auslaß (6), jedoch stärker als der Förder abschnitt (7). Die Bearbeitung der Stoffe findet im Bearbei tungsabschnitt (9) statt, während im Förderabschnitt (7) die Stoffe in den Bearbeitungsabschnitt (9) gefördert werden. Je nach Querschnittsverjüngung können die Stoffe gemischt oder homogenisiert oder plastifiziert werden.

    摘要: A blending bin for particulate having a plurality of vertically extending passageways is provided. Each passageway includes multiple vertically spaced ports. Blending vanes are provided within each passageway to control the proportion of material withdrawn from the bin through the ports. The streams of material are in turn proportionally combined into a single outlet stream. The ports are spaced such that lots of material loaded into the bin will be blended together in the outlet stream and such that thin layers of off-grade or non-uniform material will not reach disproportionate levels in the outlet stream.
