Description

Statischer Frequenzwandler, insbesondere für drahtlose Telegraphie und Telephonie. Gelegentlich bekannter Laboratoriumsversuche wurde bereits ermittelt, daß gewisse Nickel-Eisen-Legierungen, insbesondere wenn sie heiß behandelt werden, bemerkenswerte magnetische Eigenschaften besitzen.Static frequency converter, especially for wireless telegraphy and telephony. Occasionally known laboratory tests have already been determined that certain nickel-iron alloys, especially if they are hot treated, have remarkable magnetic properties.

Diese Eigenschaften wurden bei Legierungen beobachtet, welche mehr als 30 Prozent Nickel enthalten und deren innere Struktur mehr der des Nickels als der des Eisens ähnelt. Die besten Resultate wurden mit Legierungen erhalten, die ungefähr 8o Prozent Nickel und 2o Prozent Eisen enthalten. Diese Legierung ist in der Fachliteratur unter der Bezeichnung »Permalloy « bekannt. Die Permeabilität dieser Legierung ist bei schwachen Feldern ein Vielfaches derjenigen aller bisher bekannten Materialien.These properties have been observed in alloys which contain more than 30 percent nickel and whose internal structure is more similar to that of nickel than that of iron. The best results have been obtained with alloys containing approximately 80 percent nickel and 20 percent iron. This alloy is known in the specialist literature under the name "Permalloy". The permeability of this alloy in weak fields is a multiple of that of all previously known materials.

Der Gegenstand der vorliegenden Erfindung ist die Nutzanwendung dieser Laboratoriumserfolge, indem solche Eisen-_L#ickel-Legierungen, die etwa 8o Prozent Nickel und 2o Prozent Eisen enthalten, als Kern für Hochfrequenztransformatoren verwendet werden. Durch die Verwendung dieses Materials zu dem genannten Zweck wird ein außerordentlich hoher Wirkungsgrad bei Herausfilterung von höheren Harmonischen eines verzerrten Wechselstroms zum Zwecke der statischen Frequenzwandlung, insbesondere für drahtlose Telegraphie und Telephonie, erzielt.The object of the present invention is the useful application of these Laboratory success in producing such iron-nickel alloys which are about 8o percent Contains nickel and 20 percent iron, as the core for high-frequency transformers be used. By using this material for the stated purpose an extremely high degree of efficiency when filtering out higher harmonics a distorted alternating current for the purpose of static frequency conversion, in particular for wireless telegraphy and telephony.
