KAISERLICHESIMPERIAL PATENTAMTPATENT OFFICE KLASSE 78: Sprengstoffe.CLASS 78: Explosives. in CHESTER (England).in CHESTER (England). Alle explosiven körnigen Pulver, welche Nitrocellulose oder andere festen organischen Nitroverbindungen enthalten, waren bisher verhältnifsmäfsig lose in ihrer Textur und leicht zusammendrückbar, so dafs die ballistische Wirkung von solchem Pulver und die durch die Explosion im Laufe des Gewehres hervorgerufene Spannung je nach dem Compressionsgrade, welchem sie während des Ladens der Patrone oder des Gewehres unterworfen waren, sich änderten.All explosive granular powders containing nitrocellulose or other solid organic nitro compounds contained, were so far relatively loose in their texture and easily compressible, so that the ballistic effect of such powder and that of the explosion tension evoked in the course of the rifle, depending on the degree of compression it has were subjected during loading of the cartridge or rifle changed. Der Zweck dieser Erfindung ist, ein hartkörniges und homogenes Pulver herzustellen, welches im Gebrauch von den Ungleichmäfsigkeiten, die von dem verschiedenen, während des Ladens der Patronen oder Gewehre ausgeübten Drucke herrühren, frei ist.The purpose of this invention is to produce a hard-grained and homogeneous powder, which in the use of the irregularities inherent in the various while pressure exerted during the loading of the cartridges or rifles is free. Die Erfinder wenden zu diesem Zweck explosive, Nitrocellulose oder andere festen organischen Nitroverbindungen enthaltende, in üblicher Weise granulirte Pulver an. Das gekörnte Pulver wird mit Aethyl- oder Methyläther oder -Alkohol, oder mit einer Mischung derselben entweder mit einander oder mit anderen Flüssigkeiten angefeuchtet. Die Menge und Beschaffenheit der Flüssigkeit, welche für die Sättigung des körnigen Pulvers nöthig ist, hängen von der Gröfse der Körner und der Beschaffenheit der Composition ab; fünfzig bis achtzig "Volumen der Flüssigkeit genügen jedoch in den meisten Fällen, um damit hundert Volumen des in der üblichen Weise gekörnten Pulvers anzufeuchten. Nach dem Anfeuchten wird das Pulver getrocknet, wobei man die flüchtigen Theile wieder gewinnen und nachher abermals benutzen kann. Die etwas zusammenhängenden Körner werden dann durch ein Sieb gerieben und somit von einander getrennt. Das Pulver ist dann zum Gebrauch fertig.The inventors use explosive, nitrocellulose or other solid organic for this purpose Powders containing nitro compounds and granulated in the usual way. The granular powder is either with ethyl or methyl ether or alcohol, or with a mixture of the same moistened with each other or with other liquids. The amount and texture the liquid which is necessary for the saturation of the granular powder depend on the The size of the grains and the nature of the composition; fifty to eighty "volume however, in most cases, the liquid is sufficient to produce a hundred volumes of the in the usual way to moisten granular powder. After moistening, the powder is dried, the volatile parts can be recovered and used again afterwards. The somewhat coherent ones Grains are then rubbed through a sieve and thus separated from each other. The powder is then ready for use. Wenn nöthig, kann man passende Substanzen, welche in den oben erwähnten Flüssigkeiten löslich sind, diesen beimischen, entweder um das Pulver wasserdicht zu machen oder um dessen explosive Eigenschaften zu modificiren; die Erfinder haben aber gefunden, dafs Compositionen von Nitrocellulose, welche, wenn ihre Textur lose ist, hygroskopisch sind, Feuchtigkeit nicht absorbiren, wenn sie in der beschriebenen Weise gehärtet worden sind.If necessary, suitable substances can be found in the liquids mentioned above are soluble, mix them in, either to make the powder waterproof or to make it to modify its explosive properties; but the inventors have found that compositions of nitrocellulose, which when their texture is loose, are hygroscopic, moisture do not absorb when cured as described. Patenτ-Anspruch:Patenτ claim: Das Verfahren für die Härtung von explosivem, körnigem, Nitrocellulose oder andere festen organischen Nitroverbindungen enthaltenden Pulver, bestehend in der Behandlung desselben mit Aethyl-, Methyläther oder -Alkohol, oder Mischungen beider Substanzen.The process for hardening explosive, granular, nitrocellulose or others solid powder containing organic nitro compounds, consisting in the treatment of the same with ethyl, methyl ether or alcohol, or mixtures of both substances.
