Description

Es ist bekannt, die elektrisch zu erregenden Quarzscheiben mit metallischen Belägen zu versehen, die von der Umgrenzungslinie der Quarzscheibe genügenden Abstand aufweisen, um überschlag zwischen den Elektroden und damit Zerstörung der Quarze zu verhindern. Ebenso werden die Halterungen auf beiden Seitenflächen der Quarzscheiben so ausgeführt, daß die Haltearme mehr oder weniger in den Quarz oder über seine Umgrenzungsflächen fassen.It is known to electrically excite the quartz disks with metallic To provide coverings at a sufficient distance from the boundary line of the quartz disk have to flashover between the electrodes and thus destruction of the quartz crystals to prevent. Likewise, the brackets are on both side surfaces of the quartz disks designed so that the holding arms more or less in the quartz or over his Grasp the boundary areas.

Die Erfindung kennzeichnet sich dadurch, daß die Elektroden (metallischen Beläge) auf beiden Seitenflächen der Quarze mindestens diese gesamten Seitenflächen überdecken und daß zur uneingeschränkten Wahrung des daraus entspringenden offensichtlichen Vorteiles die Halterung des Quarzes so erfolgt, daß er in keinem Teile seiner Oberfläche oder seines Rauminhaltes von der Halterung selbst beansprucht wird. Der Quarz scW-#vingt vielmehr mit seinen Elektroden in einem den Quarz auf allen Umgrenzungsflächen fest und dicht berührenden Hohlraum.The invention is characterized in that the electrodes (metallic Coatings) on both side surfaces of the quartz at least these entire side surfaces cover and that for the unrestricted preservation of the obvious arising therefrom Advantageously, the quartz is held in such a way that it does not appear in any part of its surface or its volume is claimed by the bracket itself. The quartz scW- # vingt rather, with its electrodes in one, the quartz is fixed on all boundary surfaces and tightly contacting cavity.

Die Zeichnung veranschaulicht in Fig. i einen Querschnitt durch die Mitte eines Quarzes und in Fig. 2 eine Draufsicht.The drawing illustrates in Fig. I a cross section through the Middle of a quartz and in Fig. 2 a plan view.

Quarz i sitzt in einer seiner runden oder eckigrunden Form (nach Straubel) angepaßten Gummimasse 2, 3 von zweckmäßig konischer Form und ist auf beiden Seitenflächen von den metallischen Elektroden 4 und 5 überdeckt, die über die Gummiumhüllung nach allen Seiten übergreifen. Die Elektroden q. und 5 sind überdeckt durch die Glasplatten 6 und 7, die durch Zwingen 8 und 9 stark auf die Elektroden aufgepreßt werden. Die Stromzuführungen sind mit i o und i i angedeutet.Quartz i sits in one of its round or square shape (according to Straubel) adapted rubber compound 2, 3 of suitable conical shape and is on both side surfaces covered by the metallic electrodes 4 and 5, which are over the rubber cover encompass all sides. The electrodes q. and 5 are covered by the glass plates 6 and 7, which are strongly pressed onto the electrodes by forcing 8 and 9. the Power supply lines are indicated with i o and i i.

Die Elektroden sind einerseits fest verbunden mit dem Quarz und andererseits fest verbunden mit den Glasdeckplatten. Die Glasdeckplatten sollen etwa den doppelten Durchmesser aufweisen wie die Quarze.The electrodes are on the one hand firmly connected to the quartz and on the other hand firmly connected to the glass cover plates. The glass cover plates should be about twice as large Have a diameter like the quartz.

Die Einrichtung gestattet das Schwingen des Quarzes ohne Inselbildung, wie sie besonders bei ausgedehnten Quarzen zu beobachten ist. Jede Verstimmung des Quarzes als Folge seiner Halterung wird vermieden. Die Elektroden werden über die ganzen Ouarzseiltenflächen wirksam. Die Glasplatten können den Quarzschwingungen restlos folgen.The device allows the quartz to vibrate without island formation, as can be observed especially with extensive quartz crystals. Any upset of the Quartz as a result of its support is avoided. The electrodes are placed over the whole ouarz rope surfaces effective. The glass plates can absorb the quartz vibrations follow completely.
