Description

Verfahren zur Erzeugung einer Projektionsfläche Die Erfindung betrifft ein. Verfahren zur Erzeugung einer Projektionsfläche und ist dadurch gekennzeichnet, daß die in der Luftenthaltenen Staub-, Gas- und Wasserteilchen durch Hochfrequenzströme zwischen zwei sich gegenüberliegenden Hochfrequenzvorrichtungen zu -einer Wand verdichtet werden, und daß die Hochfrequenzströme beim Bilden der Wand durch elektromagnetische Felder unterstützt werden.Method for producing a projection surface The invention relates to a. Method for generating a projection surface and is characterized by that the dust, gas and water particles contained in the air by high frequency currents condensed into a wall between two opposing high-frequency devices be, and that the high frequency currents in the formation of the wall by electromagnetic Fields are supported.

Durch die Erfindung wird erreicht, in geschlossenen Räumen, insbesondere aber im Freien, mittels der in der Luft enthaltenen Wasser- -oder Staubteilchen eine Projektionsfläche ohne jedes weitere Mittel und unabhängig von Wind und Wetter zu .erzeugen, auf welche man im bekannter Weise Buchstaben, Bilder, Texte, insbesondere zu Reklamezwecken, projizieren kann.The invention achieves in enclosed spaces, in particular but outdoors, by means of the water or dust particles contained in the air a projection surface without any further means and independent of wind and weather to .generate, in which one in the known way letters, pictures, texts, in particular for advertising purposes, can project.

Die Erzeugung der Projektionsfläche erfolgt mittels Hochfrequenzströme, durch welche ein Anbellen und Ansammeln von Wasserteilchen, Gas- oder Staubteilchen in solcher Dichte erzielt wird, daß diese eine wirksame ProjektIonäschicht bilden. 'Man ordnet z: B. im Dachfirst zweier in einer Straße gegenüberliegender Häuser Hochfrequenzvorrichtungen in gleicher Höhe von der Straße an. Durch Einschalten der Hochfrequenzströme bildet sich von Dach zu Dach durch Anballung, z. B. vorn Wasser- oder Staubteilchen, eile Band in jeder gewünschten Breite, auf welches die Projektion -erfolgen kann.The projection surface is generated by means of high-frequency currents, by which a barking and accumulation of water particles, gas or dust particles is achieved in such a density that they form an effective projection layer. '' One arranges, for example, in the roof ridge of two houses opposite one another in a street High frequency devices at the same level from the street. By switching on the high-frequency currents are formed from roof to roof by accumulation, e.g. B. front Particles of water or dust, rush tape of any desired width to which the Projection can be done.
