Description
Verfahren zur Erzeugung von leuchtenden Schriftzeichen am nächtlichen Himmel mittels Flugzeuge Es ist bekannt, Schriftzeichen am Himmel dadurch zu erzeugen, daß ein Flugzeug unter Ausstoßung nebelerzeugender Stoffe Schriftzeichen an den Himmel schreibt. Diese Schriftzeichen werden entweder für militärische Zwecke (als Morsezeichen) oder aber für Zivilzwecke (als Reklameschrift) verwendet. Bedeutend eindrucksvoller als die Schrift am Tageshimmel ist eine Schrift in leuchtenden Buchstaben am nächtlichen Himmel, nur hat es bis jetzt an geeigneten Verfahren zu diesem Zweck gefehlt. Erfindungsgemäß lassen sich solche leuchtenden Schriftzeichen dadurch hervorrufen, daß das schreibende Flugzeug nicht Nebelwolken ausstößt, sondern Staub oder Flitter stark reflektierender oder lichtbrechender Stoffe. Als geeignet hierfür wurde Aluminiumstaub oder Aluminiumflitter gefunden. Da solche Reklameflüge am nächtlichen Himmel nur über Großstädten in Frage kommen, so genügt die Lichtreflektion der Stadtbeleuchtung an den glänzenden Metallflächen, um die Schrift sich als leuchtende Wollee gegen den nächtlichen Himmel abheben zu--lassen. Man kann die Wirkung noch dadurch bedeutend verstärken, daß die Schriftzüge vom Boden oder einem anderen Luftfahrzeug aus mittels Scheinwerfer in weißem oder farbigem Licht bestrahlt werden. Als Vorrichtung für die Ausstoßung der Staubwolken können die üblichen Vorrichtungen benutzt werden, wie sie z. B. für die Schädlingsbekämpfung zum Ausstoßen von Calciumarsenat verwendet werden.Process for generating luminous characters at night Sky by means of airplanes It is known to generate characters in the sky by that an aircraft emitting smoke-producing substances characters on the Heaven writes. These characters are either used for military purposes (as Morse code) or for civil purposes (as advertising font). Significant More impressive than writing in the daytime sky is writing in luminous letters in the night sky, only until now there has been an appropriate procedure for this purpose absent. According to the invention, such luminous characters can be produced by that the writing plane does not emit clouds of fog, but rather dust or tinsel highly reflective or refractive materials. Aluminum dust was found to be suitable for this or aluminum tinsel found. Since such advertisements only fly in the night sky over large cities come into question, the light reflection of the city lighting is sufficient on the shiny metal surfaces, around which the writing stands out as luminous wool to let the night sky take off. The effect can still be significant reinforce that the lettering from the ground or another aircraft by means of Headlights are irradiated in white or colored light. As a device for the usual devices can be used to expel the dust clouds, how they z. B. used for pest control to expel calcium arsenate will.
In Fällen, wo eine Reflektionsmöglichkeit nicht vorhanden ist, sondern die Schriftzeichen selbst leuchtend sein müssen, kann erfindungsgemäß eine Lösung von weißem Phosphor in öl verwendet werden. Diese Lösung muß jedoch durch Zerstäuberdüsen in feine Tröpfchenform gebracht werden. An der Berührungsfläche der Tröpfchen mit der Luft findet eine langsame Oxydation des Phosphors statt, so daß eine deutlich sichtbare Leuchterscheinung auftritt. Als Zerstäuber für die Ölflüssigkeit können die bekannten Zerstäuberdüsen Verwendung finden.In cases where there is no possibility of reflection, but rather the characters themselves must be luminous can be a solution according to the invention of white phosphorus in oil can be used. However, this solution must be through atomizing nozzles be brought into fine droplet form. At the contact surface of the droplets with In the air there is a slow oxidation of the phosphorus, so that a distinct visible glow occurs. Can be used as an atomizer for the oil liquid the known atomizer nozzles are used.
