Description

Hitzebeständige Spulen und Wicklungen Zusatz zum Patent 513 689 Gegenstand, des Hauptpatents 513 689 sind hitzebeständige Spulen und Wicklungen, bestehend aus asbestisolierten Drähten, die mit Kittmassen, die Silicofluoride enthalten, imprägniert sind. Man kann die Drähte solcher Wicklungen auf Temperaturen von ,etwa 750° erhitzen.Heat-resistant coils and windings Addendum to patent 513 689 Subject matter of the main patent 513 689 are heat-resistant coils and windings, consisting of asbestos-insulated wires, which are impregnated with cement compounds containing silicofluoride. The wires of such windings can be heated to temperatures of around 750 °.

Es wurde nun gefunden, daß die Temperatur der in die Kittmasse eingelegten Drähte auf etwa iioo°C gesteigert werden kann, wenn man der Masse größere Mengen Quarzglasmehl, im allgemeinen etwa 5o%, beimengt. Die so hergestellten Wickelkörper haben bei höheren Temperaturen eine wesentlich höhere mechanische Festigkeit, ihre Empfindlichkeit gegen Temperaturschwankungen ist 'nn wesentlichen beseitigt und das Schwinden der Masse auf Bein unbedeutendes Maß herabgedrückt. Spulen und Wicklungen können nach der irr Hauptpatent beschriebenen Arbeitsweise hergestellt werden.It has now been found that the temperature of the laid in the putty Wires can be increased to about 100 ° C. if the mass is given in larger quantities Quartz glass powder, generally about 5o%, is added. The wound body produced in this way have a significantly higher mechanical strength at higher temperatures, their Sensitivity to temperature fluctuations is essentially eliminated and the shrinkage of the mass on the leg depressed an insignificant amount. Coils and windings can be produced according to the procedure described in the main patent.

Gegenüber der bisherigen Herstellungsart; die Drähte in keramische tonhaltige Massen einzupressen und dann gegebenenfalls zu brennen, bedeutet das vorliegende Verfahren einen erheblichen Fortschritt, weil die . Anwendung hoher Drücke und Brenntemperaturen fortfällt.Compared to the previous production method; the wires in ceramic To press in clayey masses and then to burn them if necessary, that means The present proceedings represent significant progress because the. Application high Pressures and firing temperatures no longer apply.
