KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das nachstehend beschriebene Verfahren zur Herstellung von zu einem Stück verschweißten Doppelfokusgläsern (Verbundgläsern, wie in Fig. ι und 2 dargestellt) vermeidet eine Reihe'von !!beiständen und Schwierigkeiten, die sonst bei dem Verschmelzen der beiden Glasbestandteile auftreten und hat außerdem den Vorzug der billigeren Ausführung.The method described below for the manufacture of welded into one piece Double focus glasses (laminated glasses, as shown in Fig. Ι and 2) avoids one Number of !! assists and difficulties, which otherwise occur when the two glass components fuse and also has the advantage of the cheaper version.
Das Verfahren besteht im wesentlichenThe procedure essentially consists
ίο darin, daß der stärker lichtbrechende Glasteil, also die Zusatzlinse, aus kleinen Teilchen erweichten Glases aufgebaut wird, welche fortschreitend in den entsprechenden Ausschliff des Hauptglases eingebracht werden.ίο in the fact that the more refractive glass part, so the additional lens, made up of small particles of softened glass, which progressively introduced into the corresponding cutout of the main glass.
Selbstverständlich. kann man auch umgekehrt den Zusatzteil des Glases als Form benutzen und den Hauptteil auf die eben beschriebene Art herstellen, doch ist dieses Verfahren naturgemäß nicht so wirtschaftlich.Of course. the other way around, you can also use the additional part of the glass as a shape and manufacture the main part in the manner just described, but this process is natural not so economical.
Die Ausführung der Erfindung bietet keine technischen Schwierigkeiten. Man kann das Glas im gepulverten oder körnigen Zustand durch eine Flamme rieseln und die geschmolzenen Glaströpfchen in die vorgearbeitete Höhlung des Hauptteiles fallen lassen, ein Verfahren, das an sich von der Herstellung der synthetischen Edelsteine bekannt ist. Andererseits ist es aber auch möglich, nach dem bekannten Schoopschen Metallisierungsverfahren das Glas ζ. B. in Stangenform mittels einer Flamme und gleichzeitiger Einwirkung von Druckluft zu' zerstäuben und so in die Höhlung schleudern lassen. .There are no technical difficulties in carrying out the invention. You can do it Glass in powdered or granular state trickle through a flame and the melted Dropping glass droplets into the pre-machined cavity of the main part, a process which is known from the manufacture of synthetic gemstones. on the other hand but it is also possible to use the well-known Schoop metallization process Glass ζ. B. in rod form by means of a flame and the simultaneous action of compressed air to 'atomize and let it hurl into the cavity. .
Nebenher sei erwähnt, daß bei dem vorstehend beschriebenen Verfahren als Ausgangsstoff für die teilchenweise aufzubauende Linse natürlich auch fehlerhaftes (blasiges und schlieriges) Glas verwendet werden kann, das für sonstige optische Zwecke völlig wertlos ist.Incidentally, it should be mentioned that in the process described above as a starting material for the lens to be built up in parts, of course, defective (blistered and streaky) Glass can be used, which is completely worthless for other optical purposes.
