Description
In Theatern werden zur Erzielung szenischer Effekte und für Bühnenverschleierungen Vorrichtungen benutzt, die Wasserdampf von bestimmter Spannung ausströmen lassen. Das Verfahren hat im großen keine Anwendung gefunden, z. B. zur Herstellung großer zusammenhängender Vorhänge, die den bisherigen Stoffvorhang vollwertig ersetzen könnten. Denn zur Herstellung derartigerIn theaters they are used to achieve scenic effects and for stage veils Devices used that allow water vapor to flow out of a certain voltage. That Method has found no application in large, e.g. B. for the production of large contiguous Curtains that could fully replace the previous fabric curtain. Because for the production of such
ίο zusammenhängender Nebelschleier bis io m Höhe und 50 und mehr Meter Breite ist Dampf von mehreren Atmosphären Spannung und in beträchtlicher Menge nötig. Daraus ergibt sich der Nachteil, daß der Raum mit großen Wasserdampfmengen überschüttet wird, die sich in der Höhe kondensieren und als Regen herabrieseln; außerdem stört das Zischen beim Ausströmen der großen Menge hochgespannten Dampfes, und schließlich stehen auch die Kosten für den Dampf entgegen.ίο continuous veil of fog up to io m Height and width of 50 or more meters, steam of several atmospheres of tension and in considerable quantities is necessary. This has the disadvantage that the room is showered with large amounts of water vapor will condense in the air and trickle down as rain; aside from that disturbs the hissing when the large amount of high-pressure steam escapes, and finally there is also the cost of the Against steam.
Gemäß der vorliegenden Erfindung wird die Dampfmenge und Dampfspannung dadurch außerordentlich herabgesetzt, daß in den ausströmenden Dampf Preßluft eingeblasen wird. Hierdurch findet eine plötzliche Kühlung des Dampfes infolge der durch die Entspannung der Luft verursachten Wärmeentziehung statt, so daß die Undurchsichtigkeit des Schleiers bereits mit sehr geringen Dampfmengen bewirkt wird (es genügt etwa 1Z10 bis 1Z50 derjenigen Spannung, die ohne Verwendung der Preßluft notwendig wäre). Der kräftig ausströmende Luftstrom veranlaßt außerdem die Stabilisierung des Nebelschleiers, indem er den Nebelbläschen eine er-.According to the present invention, the amount of steam and the steam tension are extremely reduced in that compressed air is blown into the outflowing steam. This causes a sudden cooling of the steam as a result of the removal of heat caused by the expansion of the air, so that the opacity of the veil is already made with very small amounts of steam (about 1 Z 10 to 1 Z 50 of the voltage that can be achieved without the use of compressed air is sufficient would be necessary). The powerful outflow of air also causes the fog veil to stabilize by engaging the fog bubbles.

Die Erfindung ist auf der Zeichnung in zwei Figuren schematisch dargestellt.The invention is shown schematically in the drawing in two figures.
Fig. ι zeigt eine zylindrische Düse a, in deren Hohlraum sich zentrisch die Zuführung d für die Preßluft befindet, die durch die Rohrleitung l· eintritt, während der Wasserdampf durch das Rohr c in die Düse strömt. Die Anordnung, die auch in anderer Weise getroffen werden kann, ermöglicht die Herstellung einzelner Nebelsäulen, die durch Nebeneinandersetzen gleichartiger Düsen zu einer zusammenhängenden Wand ausgebildet werden können.1 shows a cylindrical nozzle a, in the cavity of which the feed d for the compressed air is centrally located, which enters through the pipeline l , while the water vapor flows through the pipe c into the nozzle. The arrangement, which can also be made in a different way, enables the production of individual fog columns, which can be formed into a coherent wall by juxtaposing similar nozzles.
Fig. 2 zeigt eine andere Anordnung, die es gestattet, ohne Einzeldüse eine zusammenhängende Nebelwand herzustellen. Das Dampfrohr i, in dem der Wasserdampf strömt, hat an seinem Scheitel einen beliebig langen Schlitz /, unter dem ein mit Löchern versehenes Rohr k, aus dem die Preßluft ausströmt, so angeordnet ist, daß die Gasstrahlen in den Dampfschleier einströmen. Die Rohre h und g, die in beliebiger Anzahl nach Erfordernis angeordnet werden können, dienen zur Zuführung des Wasserdampfes bzw. der Preßluft.FIG. 2 shows another arrangement which makes it possible to produce a coherent smoke screen without a single nozzle. The steam pipe i, in which the steam flows, has at its apex a slot of any length / under which a perforated pipe k, from which the compressed air flows, is arranged so that the gas jets flow into the steam curtain. The tubes h and g, which can be arranged in any number as required, are used to supply the steam or the compressed air.
