Description
Schreibfläche für Registriervorrichtungen Bisher erfolgte die Aufzeichnung von Zeitvorgängen unter Zuhilfenahme einer mit einer Schreibfeder verbundenen Stimmgabel, z. B. bei Rücklaufmessern für innere Ballistik, auf einer mit Ruß geschwärzten Glasplatte. Will man nun Zeitregistrierungen mit einer sehr schnell schwingenden Stimmgabel vornehmen, welche z. B. iooo Schwingungen pro Sekunde ausführt, so genügt eine solche Aufzeichnungsplatte nicht mehr. Die aufgezeichneten Kurven werden ungenau und sind für eine Auswertung nicht mehr zu gebrauchen.Writing surface for registration devices So far, the recording has been made of time processes with the help of a tuning fork connected to a pen, z. B. for return knives for internal ballistics, on a glass plate blackened with soot. If you want time registrations with a tuning fork that vibrates very quickly make what z. B. executes 10000 vibrations per second, one is sufficient Recording disk no longer. The recorded curves are inaccurate and are no longer usable for an evaluation.
Es sind daher auch schon Schreibflächen aus einem lichtdurchlässigen Träger, insbesondere Glas, zur Anwendung gekommen, die mit einem undurchsichtigen Überzug aus einer dünnen Metallschicht, vorzugsweise aus Silber, versehen waren. Es hat sich aber herausgestellt, daß Silberschichten für den oben angegebenen Zweck auch nicht geeignet sind, da diese Schicht bei der Gravierung ausreißt und abblättert, was aber in Fällen, wo die Registrierkurven sehr eng aneinander zu liegen kommen und so dünn sind, daß sie erst bei etwa 5ofacher Vergrößerung ausgewertet werden können, von großem Nachteil ist. Um diese Nachteile zu beseitigen, soll nach der Erfindung daher für eine derartige Registrierung eine Glasplatte Verwendung finden, welche mit einer dünnen Goldschicht überzogen ist. Das Aufbringen des Goldes kann in bekannter Weise auf dem Wege der Kathodenzerstäubung erfolgen. Der auf diese Weise auf die Glasplatte aufgebrachte Überzug ist so gleichmäßig, daß die Schreibfeder der Stimmgabel eine vollkommen scharfe Markierung ergibt und die aufgezeichneten Schwingungen bequem unter einem Mikroskop ausgewertet werden können.There are therefore already writing surfaces made of a translucent one Carriers, especially glass, have been used with an opaque Coating of a thin metal layer, preferably silver, were provided. However, it has been found that silver layers can be used for the above-mentioned purpose are also not suitable, as this layer tears off and flakes off during engraving, but what in cases where the registration curves come very close to one another and are so thin that they can only be evaluated at about 5x magnification can, is of great disadvantage. In order to eliminate these disadvantages, after the Invention therefore find a glass plate use for such a registration, which is covered with a thin layer of gold. Applying the gold can take place in a known manner by way of cathode sputtering. The one on this The way the coating is applied to the glass plate is so even that the nib the tuning fork gives a perfectly sharp mark and the recorded Vibrations can be conveniently evaluated under a microscope.
