Abstract
In a pyrotechnic composition that continuously burns down, graphite compounds that form additional components of the composition are capable of thermally expanding in the c-axis perpendicular to the plane of the grid, expand in the reaction zone of the pyrotechnic composition and are released together with the reaction products of the burning pyrotechnic composition. Camouflage fogs may thus be generated that are effective in the optically visible range, in the IR range and in the millimetre range of electromagnetic radiation.
Claims
1. Pyrotechnischer Nebelsatz für Tarnzwecke, dadurch gekennzeichnet, daß in einem kontinuierlich abbrennenden pyrotechnischen Nebelsatz zur thermischen Expansion fähige Verbindungen von Graphit eingebracht sind, die in der Reaktionszone des pyrotechnischen Satzes freigegeben werden und dort expandieren, wobei die Expansion der Verbindungen des Graphits in Richtung der zur Gitterebene senkrechten c- Achse erfolgt.1. Pyrotechnic fog set for camouflage purposes, characterized in that in a continuously burning pyrotechnic mist set for thermal expansion capable compounds of graphite are introduced, which are released in the reaction zone of the pyrotechnic composition and expand there, wherein the expansion of the compounds of graphite in the direction of to the grid plane vertical c-axis takes place.

Nebelsatz nach Anspruch 1, dadurch gekennzeichnet, daß der kontinuierlich abbrennende pyrotechnische Satz Reaktionsprodukte erzeugt, welche im sichtbaren Bereich des Spektrums der elektromagnetischen Strahlung einen tarnfähigen Nebel bilden.2. mist set according to claim 1, characterized in that the continuously burning pyrotechnic set generates reaction products which form a camouflaged fog in the visible region of the spectrum of electromagnetic radiation.
3. Nebelsatz nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Verbindungen von Graphit in einem Anteil zwischen 40 und 65 Gewichtsprczer- , vorzugsweise etwa 50 Gewichtsprozent, im pyrotechnischen Nebelsatz vorliegen.3. fog set according to claim 1 or 2, characterized in that the compounds of graphite in a proportion between 40 and 65 Gewichtssprczer-, preferably about 50 weight percent, are present in the pyrotechnic fog set.
4. Nebelsatz nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß die in der Reaktionszone des pyrotechnischen Satzes expandierten Teilchen im wesentlichen strangförmig sind und Dimensionen zwischen 0,001 und 10 Millimeter, vorzugsweise zwischen 0,001 und 5 Millimetern aufweisen.4. mist set according to one of the preceding claims, characterized in that the particles expanded in the reaction zone of the pyrotechnic composition are substantially strand-shaped and have dimensions between 0.001 and 10 millimeters, preferably between 0.001 and 5 millimeters.
5. Nebelsatz nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß dem pyrotechnischen Nebelsatz zusätzlich Graphitpulver beigemischt ist.5. Fog set according to one of the preceding claims, characterized in that the pyrotechnic mist additionally graphite powder is admixed.
6. Nebelsatz nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß die expandierende Graphi erbindung Graphithyrogensulfat ist. INARTIKEL19GENANNTEERKLÄRUNG6. mist set according to one of the preceding claims, characterized in that the expanding Graphi compound is graphite hydrogen sulfate. INARTIKEL19GENANNTEERKLÄRUNG
In dem neuen Patentanspruch 1 sind die Graphi Verbindungen bereits bei der ersten Erwähnung als "zur thermischen Expansion fähige" Verbindungen bezeichnet; ferner ist klargestellt, daß die GraphitVerbindungen in der Reaktionszone des pyrotechnischen Satzes expandieren. In the new claim 1, the Graphi compounds are already designated at the first mention as "thermal expansion capable" compounds; it is further clarified that the graphite compounds expand in the reaction zone of the pyrotechnic charge.
