Abstract

Σε κυκλώματα ταλαντώσεων κατασκευαζόμενα απο ένα κυλινδρικό προϊόν συνδετικής μεμβράνης με συχνότητες κείμενες κάτω από την ονομαστική συχνότητα, που συνδέονται μεταξύ τους μέσω μιας τουλάχιστον κοινής συνθετικής μεμβράνης, για την προσαρμογή της ζώνης συχνοτήτων των κυκλωμάτων ταλαντώσεων των αποτελουμένων από μια συνδετική μεμβράνη μετάλλου- συνθετικού υλικού-μετάλλου για ετικέττες αναγνωρίσεως, υπό σχεδόν συνεχή κίνηση δια μέσου δύο μετρητικών κυψελών συχνότητος 5,6 με μία μεταξύ τους κείμενη μονάδα βραχύνσεως 7 και μέσω συγκρίσεως ονομαστικής/πραγματικής τιμής, προσαρμόζεται η ζώνη συχνοτήτων ενός κυκλώματος ταλαντώσεως κατόπιν βραχύνσεως του τμήματος πυκνωτού του κυκλώματος τούτου ταλαντώσεως, και με την βοήθεια της μονάδας βραχύνσεως 7 που ρυθμίζεται δια της διορθωτικής μονάδας 8. Η θέσις της μονάδας βραχύνσεως 7 που καθορίζεται από την διορθωτική μονάδα χρησιμοποιείται ως τιμή βάσεως κατά την ρύθμιση της μονάδας βραχύνσεως 7, για ένα επόμενο κύκλωμα ταλαντώσεως, οπότε για την τελική ρύθμιση της μονάδας βραχύνσεως 7 ώστε να βραχύνεται το επόμενο κύκλωμα ταλαντώσεως θα πρέπει να εκτελούνται μόνο ελάχιστες διορθώσεις. Η μέθοδος είναι χρησιμοποιήσιμη όταν η συνδετική μεμβράνη δεν χρειάζεται, κατόπιν επιλεκτικής επιλογής των συστατικών στοιχείων και των διαστασεών τους, έντονες αποκλίσεις της συχνότητος σε κυκλώματα ταλαντώσεως που δεν ευρίσκομαι σε πολύ μεγάλη απόσταση μεταξύ τους. ωIn oscillation circuits made of a cylindrical product of a connecting membrane with frequencies below the nominal frequency, connected to each other through at least one common synthetic membrane, to adapt the frequency band of the oscillation circuits of those composed of a connecting membrane of metal-synthetic material- of metal for identification tags, under almost continuous movement through two frequency measuring cells 5,6 with a shorting unit 7 located between them and by means of nominal/actual value comparison, the frequency band of an oscillating circuit is adjusted after shortening the capacitor part of this oscillating circuit , and with the help of the shortening unit 7 adjusted by the correction unit 8. The position of the shortening unit 7 determined by the correction unit is used as a base value during the adjustment of the shortening unit 7, for a subsequent oscillation circuit, so for the t helical adjustment of the shortening unit 7 to shorten the next oscillating circuit only minimal corrections should be performed. The method is usable when the connecting membrane does not need, after a selective selection of the components and their dimensions, sharp deviations of the frequency in oscillating circuits that are not very far apart. oh
