Description
wurde gleichzeitig durch die Öffnimg 7 die Zündschnur eingeführt. Die Zündung erfolgte elektrisch.At the same time, the fuse was inserted through the opening 7. The ignition was electrical.
Das verwendete Glaspulver hatte folgende Zusammensetzung: The glass powder used had the following composition:
B2O3 13 Gewichtsprozent, La2O3 38 Gewichtsprozent, ThO2 24 Gewichtsprozent, Nb2O3 8 Gewichtsprozent, Ta2O5 17 Gewichtsprozent.B 2 O 3 13 percent by weight, La 2 O 3 38 percent by weight, ThO 2 24 percent by weight, Nb 2 O 3 8 percent by weight, Ta 2 O 5 17 percent by weight.
Das kompakte Glas wies nach dem Verdichten einen Brechwert von /^ 2,02 auf. Dieses Glas läßt sich nach einem der üblichen Schmelzverfahren nur in sehr kleinen Einheiten herstellen.After compression, the compact glass had a refractive index of / ^ 2.02. This glass lets can only be produced in very small units using one of the usual melting processes.
2. Der Druckbehälter wurde, wie unter 1. beschrieben, hergerichtet. Das Glaspulver hatte folgende Zusammensetzung: 2. The pressure vessel was prepared as described under 1.. The glass powder had the following composition:
CaF2 23 Gewichtsprozent, SrF2 32 Gewichtsprozent, LaF3 2 Gewichtsprozent, AlF3 22 Gewichtsprozent, NaPO3 21 Gewichtsprozent.CaF 2 23 percent by weight, SrF 2 32 percent by weight, LaF 3 2 percent by weight, AlF 3 22 percent by weight, NaPO 3 21 percent by weight.
Das kompakte Glas wies nach dem Verdichten einen Brechwert von nd 1,5527 auf. Nach einem der üblichen Schmelzverfahren wird bei dieser Glaszusammensetzung nur ein Brechwert von nd 1,4644 erreicht.After compression, the compact glass had a refractive index of n d 1.5527. According to one of the usual melting processes, this glass composition only has a refractive index of n d 1.4644.
3. Bei Verwendung von gereinigtem und getrocknetem Lithiumfluoridpulver als zu verdichtende Substanz wurde ein kompaktes Material mit 98% der theoretischen Dichte erhalten. Es zeichnete sich durch besonders gute Durchlässigkeit im sichtbaren und im infraroten Spektralbereich aus.3. When using purified and dried lithium fluoride powder as the substance to be compressed a compact material with 98% of the theoretical density was obtained. It stood out due to particularly good permeability in the visible and infrared spectral range.
