KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Pyrophore, d. h. beim Ritzen mit genügend harten Körpern funkengebende Metallegierungen sind bisher erhalten worden durch Einfügung von gewissen Prozentsätzen Schwermetall in die elektrolytisch erschmolzenen, für sich kaum funkenden Legierungen der Metalle der sogenannten Edelerden (D. R. P. 154807).Pyrophores, d. H. when scratching with enough Hard body sparking metal alloys have heretofore been obtained by incorporation of certain percentages of heavy metal in the electrolytically melted, hardly sparking alloys of the Metals of the so-called precious earths (D. R. P. 154807).
Erfinderin hat nun gefunden, daß es einer derartigen Legierung mit Schwermetall garnicht bedarf, um die Metalle der Edelerden oder deren Gemische pyrophor zu gestalten, und daß diese Metalle ohne weiteres gewisse pyrophore Eigenschaften aufweisen, wenn sie zerkleinert durch hohen Druck verdichtet sind. Durch das dichter gestaltete Gefüge wird bedingt, daß bei Abtrennung kleiner Teilchen von den gepreßten Massen ein höherer Wärmegrad erzeugt wird, welcher ausreicht, um die Teilchen zur Reaktion mit dem Sauerstoff der Luft, d. h. zur Entzündung, zu bringen.The inventor has now found that such an alloy with heavy metal is not at all required to make the metals of the noble earths or their mixtures pyrophoric, and that these metals readily certain Have pyrophoric properties when crushed and compressed by high pressure. The denser structure means that small particles are separated a higher degree of heat is generated by the pressed masses, which is sufficient to the Particles to react with the oxygen in the air, d. H. to cause inflammation.
Es wurde weiter gefunden, daß die pyrophore Eigenschaft der verdichteten Metalle wesentlich erhöht wird durch geeignete Zusätze, welche beim Ritzen eine Erhöhung der Wärmeentwicklung infolge ihrer Härte hervorrufen und damit die Reaktion der Erdmetallteilchen mit dem Sauerstoff der Luft einleiten (z. B. Carborundum, Bor, Silicium, Metalle in pulverigem Zustande) oder aber infolge der durch die Reibung erzeugten Wärme mit den abgetrennten Teilchen des Erdmetalles unter gesteigerter Wärmeerzeugung chemisch reagieren (Oxyde, Superoxyde, Salze, Phosphor, Schwefel, Arsen, Antimon). Eventuell können beide Arten Zusätze zugleich in Anwendung gebracht werden, so daß beide Wirkungen nebeneinander vor sich gehen. Die Menge der Zusätze wird zweckmäßig im Einzelfall auf das Optimum der Wirkung bemessen. It was further found that the pyrophoric property of the densified metals is significantly increased by suitable additives, which when scratching an increase in the Induce heat generation due to their hardness and thus the reaction of the earth metal particles introduce with the oxygen in the air (e.g. carborundum, boron, silicon, metals in powdery state) or else as a result of the heat generated by the friction with the separated particles of the earth metal with increased heat generation react chemically (oxides, super oxides, salts, phosphorus, sulfur, arsenic, antimony). Possible Both types of additives can be used at the same time, so that both Effects happen side by side. The amount of additives is appropriate in the Measure individually for the optimum of the effect.
