BIDTEL und FILLEN in MITTELWALDE.
Sicherheitszünder mit die Pulverseele einschließender wasserdichter Garnhülle.BIDTEL and FILLEN in MITTELWALDE.
Safety fuse with a waterproof thread cover enclosing the powder core.
Patentirt im Deutschen Reiche vom 21. August 1877 ab.Patented in the German Empire on August 21, 1877.
Der bisherige Sicherheitszünder für Massenbesatz besteht aus einem mit einer oder mehreren Schichten Guttapercha überzogenen rohen Bickfordzünder. Dieser Ueberzug hat den Nachtheil, dafs er:The previous safety detonator for mass occupation consists of one with one or more Layers of gutta-percha coated raw Bickford fuse. This coating has the disadvantage that he:
1. mit der Zeit spröde wird, und1. becomes brittle over time, and
2. dafs er, irgend wie verletzt, dem Wasser gestattet, das die Pulverseele umhüllende rohe Gespinnst zu nassen und damit den Brand des Zünders zu verlöschen.2. that he, somehow injured, allows the water to be raw which envelops the powder soul Spun too wet and thus extinguish the fire of the detonator.
Unsere Verbesserung des Zünders besteht nun darin, dafs wir:Our improvement of the detonator consists in that we:
1. den Zünder so imprägniren, dafs er auch ohne äufsere Hülle im Wasser brennt, und1. impregnate the detonator so that it burns in the water even without an outer cover, and
2. dafs wir ihn mit einem Ueberzug versehen, der wesentlich den Zweck hat, den imprägnirten Zünder dem Einflufs der Luft zu entziehen, dabei aber niemals spröde wird.2. that we provide it with a coating which essentially has the purpose of impregnating it To withdraw the igniter from the influence of the air, but never become brittle.
Dieses Ziel erreichen wir durch eine eigenthümliche Behandlung des Steinkohlentheers.We achieve this goal by a peculiar treatment of the coal horse.
Wir dampfen nämlich zuvörderst das Wasser vom Theer ab, setzen dann 30 pCt. pulverisirte Laming'sche Masse und 2opCt. Gaskalk zu und kochen das Gemenge unter Zusatz von 10 ρ Ct. Salmiak. Ein so zubereiteter Theer, auf den Zünder in geeigneter Weise aufgetragen, hat die Eigenschaft:First of all we steam the water from the tar, then add 30 pCt. pulverized Laming mass and 2opCt. Gas lime and boil the mixture with the addition of 10 ρ Ct. Salmiac. A tar prepared in this way, applied in a suitable manner to the detonator, has the Characteristic:
1. den Zünder elastisch zu erhalten;1. to keep the detonator elastic;
2. ihn gegen Wasser unempfindlich zu machen,2. to make it insensitive to water,
3. ihn zu befähigen, mit einem äufseren gleichmäfsigen Ueberzug versehen zu werden, und3. to enable it to be provided with an outer uniform coating, and
4. was die Hauptsache ist, beim Brande des Zünders derart fest zu bleiben, dafs derselbe nicht etwa durch das Eindringen der schmelzenden Theercomposition in die Pulverseele erlischt. 4. What is the main thing, when the detonator burns, to remain so firm that it stays the same does not go out through the penetration of the melting tar composition into the powder core.
Die über den imprägnirten Zünder gezogene Umhüllung besteht zur Hälfte aus Guttapercha, zur anderen Hälfte aus unserer Theercomposition, bleibt im Gegensatz zu reinem Guttapercha immer elastisch und verbindet sich auf das innigste mit dem' darunter befindlichen Theercompositionszünder. Half of the covering pulled over the impregnated fuse consists of gutta-percha, the other half from our tar composition, unlike pure gutta-percha always elastic and connects in the most intimate way with the 'composition fuse below.
