Description

Instrumentenglas mit leitfähiger Schicht Die Erfindung betrifft ein Instrumentenglas mit leitfähiger Schicht.Instrument glass with conductive layer The invention relates to a Instrument glass with conductive layer.

Ein großer Nachteil der bisher bekannten Instrumentengläser besteht darin, daß diese sich elektrostatisch aufladen, wodurch das Arbeiten mit Präzisionsinstrumenten beeinträchtigt wird und Fehlmessungen entstehen.There is a major disadvantage of the hitherto known instrument glasses in that they become electrostatically charged, which makes working with precision instruments is impaired and incorrect measurements occur.

Zur Vermeidung einer solchen elektrostatischen Aufladung von Instrumentengläsern ist es bereits bekannt, diese teilweise zu metallisieren, wobei dann die Teile der Scheibe, durch welche hindurch die Ablesung vorgenommen wird, nicht metallisiert werden. Hierdurch wird aber nur eine unvollkommene Leitfähigkeit erzielt, und es besteht die Gefahr, daß der Zeiger des Meßinstrumentes gerade an dem durchsichtig bleibenden Teil des Fensters durch elektrostatische Anziehung haften bleibt.To avoid such an electrostatic charge on instrument glasses it is already known to partially metallize this, in which case the parts of the Disc through which the reading is taken, not metallized will. As a result, however, only an imperfect conductivity is achieved, and it there is a risk that the pointer of the measuring instrument is just at the transparent The remaining part of the window will adhere to it due to electrostatic attraction.

Es ist weiter bereits bekannt, die gesamte Glasscheibe durch Aufdämpfen von halbdurchsichtigen Metallschichten oder Halbleiterschichten leitfähig zu machen. Da Instrumentengläser insbesondere in Fabrikbetrieben wegen der starken Einstäubung häufig gewischt und geputzt werden müssen, werden die dünnen aufgedampften Schichten wegen der begrenzten Wischfestigkeit leicht beschädigt oder zerstört. Außerdem verschluckt jede aufgedampfte Schicht einen Teil des auffallenden Lichtes, so daß die Skalen stets verhältnismäßig dunkel oder trübe erscheinen und sich daher beim Ablesen Schwierigkeiten ergeben. Schließlich ist auch das Aufdampfen von leitfähigen Schichten im Hochvakuum verhältnismäßig kostspielig.It is also already known to vaporize the entire pane of glass of semi-transparent metal layers or semiconductor layers to make conductive. As instrument glasses especially in factories because of the heavy dusting The thin vapor-deposited layers have to be wiped and cleaned frequently Easily damaged or destroyed due to the limited wipe resistance. Also swallowed each vapor deposited layer part of the incident light, so that the scales always appear relatively dark or cloudy and therefore difficult to read result. Finally, there is also the vapor deposition of conductive layers in a high vacuum relatively expensive.

Erfindungsgemäß werden diese Nachteile dadurch vermieden, daß die leitfähige Schicht die Zwischenschicht eines mehrschichtigen Glases bildet.According to the invention these disadvantages are avoided in that the conductive layer forms the intermediate layer of a multilayer glass.

Als besonders geeignet haben sich solche Mehrschichtengläser erwiesen, deren Zwischenschicht ionisierte Metallsalze enthält. Die Zwischenschicht kann dabei aus einer Flüssigkeit bestehen, in der die Metallsalze gelöst sind, und die in dem von einer Doppelglasscheibe eingeschlossenen Hohlraum angeordnet ist.Such multilayer glasses have proven to be particularly suitable, the intermediate layer of which contains ionized metal salts. The intermediate layer can consist of a liquid in which the metal salts are dissolved, and which is arranged in the cavity enclosed by a double pane of glass.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die ionisierten Metallsalze aber in einer filmartigen Zwischenschicht angeordnet, wobei der Film die Deckscheiben nach der Art des Sicherheitsglases vereinigt.According to a preferred embodiment of the invention, the ionized Metal salts but arranged in a film-like intermediate layer, the film the cover panes combined according to the type of safety glass.
