摘要:
Mixing systems and methods include a mixing device comprising a primary tube having a proximal end, a distal end, an outer surface and an inner lumen and at least one secondary tube having a proximal end, a distal end, an outer surface and an inner lumen. The at least one secondary tube is substantially parallel to the primary tube. The distal end of the at least one secondary tube is fluidly connected to the primary tube at a junction located on the primary tube close to the distal end of the primary tube.
摘要:
Ein Verfahren zur Nassbeleimung von Holzfasern, die zuvor in einem Refiner (4) aus zu Schnitzeln zerkleinertem Holz zerfasert wurden, damit diese nach der Nassbeleimung in einer Beleimungszone (BZ) in einem Trockner (5) getrocknet, anschließend in einer Streuvorrichtung (6) zu einem Faserkuchen gestreut und in einer Heißpresse (7) zu einer Holzwerkstoffplatte gewünschter Dicke verpresst werden können, wobei die Holzfasern innerhalb eines Förderrohres (R) in einem Strom aus gesättigtem Dampf in die Beleimungszone (BZ) transportiert werden, zeichnet sich dadurch aus, dass - zur Beruhigung des Faserstromes das Förderrohr (R) sich am Anfang (A) der Beleimungszone (BZ), innerhalb der sich eine Mehrzahl von Beleimungsdüsen (D 1 , D 2, ... D i, ... D L ) befindet, aufweitet, wodurch die Geschwindigkeit des Faserstromes noch vor dem Erreichen der ersten Beleimungsdüse D 1 reduziert wird, - die Fasern in dem beruhigten Faserstrom mittels der Beleimungsdüsen (DE, D 2 ,... D i ,... D L mit Klebstoff beleimt und dann - dem Trockner (5) zugeführt werden.

The invention relates to a device for the purification of exhaust gases for an exhaust strand of an internal combustion engine, having an exhaust-gas duct which is of multi-flow design in a predefined region and which has a plurality of partial exhaust strands (4, 5), and having a dosing device (14), by means of which a predefined quantity of a reducing agent can be dosed into the exhaust-gas duct in the region upstream of a catalytic converter arrangement (7, 8) at predefined times. According to the invention, each of the partial exhaust strands (4, 5) is assigned a dosing duct (19, 20) which branches off from a single dosing device (14), wherein a predefined proportion of the dosed reducing agent quantity can be supplied via the dosing ducts (19, 20) to each partial exhaust strand (4, 5).

A water emulsion production apparatus characterized by comprising a water emulsion container, a pump for applying a pressure to an oil-water mixture, an injection nozzle injecting the oil-water mixture supplied through the pump into the water emulsion container, and a collision plate which is arranged opposed to the injection nozzle in the water emulsion container and with which the oil-water mixture injected through the injection nozzle is caused to collide.
摘要:
Eine Misch- und Knetanordnung (1) hat einen Knetbottich (2) und mindestens ein Knetwerkzeug (3, 4). Eine Sprüheinrichtung (14) der Anordnung (1) hat mindestens eine Sprühdüse (10) zur Erzeugung eines Sprühnebels im Knetbottich (2). Ferner hat die Sprüheinrichtung (14) eine Zuführeinrichtung (31) zum Zuführen von flüssigen oder verflüssigten Teigkomponenten zu der Sprühdüse (10). Die Sprüheinrichtung (14) hat weiterhin eine Quelle (26, 29) für ein sauerstoffhaltiges Gas und eine Druckeinheit (27, 30), die das sauerstoffhaltige Gas unter Druck setzt. In einem Sprühkopf der Sprühdüse (10) werden die flüssigen oder verflüssigten Teigkomponenten mit dem unter Druck stehenden sauerstoffhaltigen Gas zur Erzeugung des Sprühnebels vereinigt.
摘要:
In at least one embodiment, the present invention relates to a method and system for providing blends of virgin polyethylene terephthalate (VPET) and a VPET property modifying component (PCM). In one embodiment, separate sources of solid VPET (12) and solid PMC (16) are provided. A conduit (10) is provided between the sources and a bulk-container, which is suitable for delivery to an end user. VPET from the source of VPET and PMC from the PMC source are selectively dispensed into the conduit in a desired amount to form a uniform blend of materials comprising a predetermined ratio of VPET relative to PMC. The blend of materials is transported to the bulk-container for delivery to an end user.

The invention relates to a device (1) comprising at least two juxtaposed compressed-gas containers (2, 3) which each contain a foamable liquid product (4, 5) containing a liquefied propellant gas. Both compressed-gas containers (2, 3) are provided with a valve (6, 7; 6.1, 7.1) and both of said valves (6, 7; 6.1, 7.1) can be jointly actuated by means of an attachment (8, 8.1). By way of the attachment (8, 8.1) each valve (6, 7; 6.1, 7.1) is provided with a connecting port (9, 10). Said connecting ports (9, 10) discharge into a mixing chamber (11) which is linked to an expansion port (12) whose one end has a foam delivery opening (13). The cross-sections of the connecting ports (9, 10) and the mixing chamber (11) are so small that during the dispensing of a product the products (4, 5) flowing through the connecting ports (9, 10) and the mixing chamber (11) remain in the liquid phase.
