Abstract:
Verfahren und eine Vorrichtung zum Trocknen von zur Herstellung von Faserplatten vorgesehenen Fasern, die zuvor im trockenen Zustand mit Leim benetzt worden sind. Die mit Leim benetzten Fasern werden von unten axial durch einen vertikal verlaufenden Fasertrockner mittels Transportluft hindurchgesaugt. Bei dem Fasertrockner handelt es sich um einen vertikal aufgerichteten Trocknungsturm (21) und die Fasern werden im Wesentlichen über dessen gesamte Länge hindurchgesaugt. Die Transportluft strömt durch ringförmige Spalte (25) hindurch in den Trocknungsturm. Die ringförmigen Spalte sind in einem Mantel (26) des Trocknungsturmes übereinander angeordnet und in Gruppen von benachbarten ringförmigen Spalten Warmluftversorgungskammern (24) zugeordnet. Die Warmluftversorgungskammern (24) sind über die Länge des Trocknungsturmes (21) angeordnet und führen dem Trocknungsturm (21) über seine Höhe unterschiedlich einstellbare Warmluftmengen pro Zeiteinheit zu.

Abstract:
A device for dispensing individual components of a two-component adhesive includes first and second manifold members, each having a distribution chamber therein. A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. The second manifold member has an array of passages therethrough. Each tube extends substantially concentrically through a respective passage to define annular flow spaces that collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. First and second components emanating from the tubes and the flow spaces are able to intermix with and diffuse into each other on the discharge area of the second manifold member. The cross-sectional flow areas presented to the first and second distribution chambers are equal.
Abstract:
A device for analyzing a whole blood sample is provided. The device comprises a conventional hematology analyzer integrated with a fluorescence cyometry analyzer. A controller is provided for controlling the analyzers, obtaining and utilizing data from both and reporting a quantitative result. Methods are also provided for analyzing a whole blood sample. One such method comprises the steps of performing on a single instrument an analysis of impedance associated with the blood sample, an analysis of light scatter associated with the blood sample, and an analysis of fluorescence associated with the blood sample. Data is collected and utilized. A result is reported.
Abstract:
The present invention generally relates to multiple emulsions, and to methods and apparatuses for making multiple emulsions. A multiple emulsion generally describes larger droplets that contain one or more smaller droplets therein. The larger droplets may be suspended in a third fluid in some cases. These can be useful for encapsulating species such as pharmaceutical agents, cells, chemicals, or the like. In some cases, one or more of the droplets can change form, for instance, to become solidified to form a microcapsule, a liposome, a polymerosome, or a colloidosome. Multiple emulsions can be formed in one step in certain embodiments, with generally precise repeatability, and can be tailored to include one, two, three, or more inner droplets within a single outer droplet (which droplets may all be nested in some cases).
Abstract:
A mixing apparatus includes coaxial first and second nozzles (104,105) that taper toward respective discharage ends (110,132) and that have rectangular cross sections. The apparatus may be used to mix fluids, for example to mix phosgene with amines to produce and isocyanates.
Abstract:
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Herstellen eines Schaums. Hierbei durchströmt ein Fluid (Fl 1 ) einen kanalförmig ausgebildeten Zuführraum. Das Fluid (Fl 1 ) tritt durch eine Öffnung an einem Ende des Zuführraums aus dem Zuführraum aus und gelangt zum Bilden von Einlagerungen des Fluids (Fl 1 ) in eine die Öffnung umgebende Bildungskammer. Ein anderes Fluid (Fl 2 ) wird in der Bildungskammer eingebracht, so daß es an der Öffnung vorbeiströmt. Beim Austreten des Fluids Fl 1 aus dem Zuführraum durch die Öffnung werden in dem an der Öffnung vorbeiströmenden Fluids (Fl 2 ) Einlagerungen des Fluids (Fl 1 ) gebildet, wobei eine Ausdehnung der Einlagerungen durch eine Abmessung der Bildungskammer im Bereich der Öffnung begrenzt wird und die Abmessung der Bildungskammer im Bereich der Öffnung kleiner oder gleich einer Ausdehnung einer Blasen/eines Tropfens des Fluids (Fl 1 ) in einem freiströmenden Fluidstrom des anderen Fluids (Fl 2 ) ist. Zum Ausbilden eines Schäums strömt das andere Fluid (Fl 2 ) mit den Einlagerungen in einen Sammelraum.
Abstract:
The invention relates to reactor apparatus (1) comprising an assembly of a plurality of separate conduits (2) disposed within a vessel (3) for heat exchange between the conduits (2) and a medium (not shown) in the vessel (3), the separate conduits (2) being connectible to define one or more flow paths through the reactor (1), the length of the or each flow path being variable by adjusting the number of conduits connected such that the residence tine of reactants flowing in the or each flow path can be varied, and a mixing inlet (100) for mixing fluids comprising a conduit (200) adapted to be inserted into a fluid flow device (300) and means (400) disposed about the outer surface (700) of the conduit (200) to create turbulence in fluid in the device (300), there being at least one aperture (600) in the conduit (200) for addition and an additive, the turbulence causing mixing of the additive into the fluid show. Such a mixing inlet (100) can be used with reactor apparatus as described above.
Abstract:
A device (10) for dispensing individual components of a two-component adhesive includes first (12) and second (14) manifold members, each having a distribution chamber (12C, 14C) therein. A set of conveying tubes is supported within the dispensing device and collectively present a predetermined total cross-sectional flow area to the first distribution chamber. An array of openings (14G) and an array of passages (14P) extend through the second member (14). The openings receive the discharge ends of the conveying tubes. The passages are disposed in fluid communication with the second distribution chamber (14C). The passages collectively present a predetermined total cross-sectional flow area to the second distribution chamber member. The openings and the passages are laterally spaced with respect to each other such that the discharge ends of the tubes are interspersed among the passages.
