Description
Verfahren zur Aufzeichnung von Tonschwingungen auf lichtempfindlichen Materialien Die Erfindung betrifft eine vorteilhafte Weiterbildüng des! Verfahrens zum Aufzeichnen, voln Ton, schwingungen gemäZ Patent S35 Sio. Bei diesem Verfahren gemäß dem Hauptpatent wird die in an. sich bekannter Weise mit einer kapillaren Einschnürung als Belichtungsquelle versehene Entla,-dungs,röhre mittels Hochfrequenzspannung, die rait den aufzuzeichnenden, Tänischwinpgungen mold'uliert wird, zum Leuchten gebracht. Es wird hierbei die positive Säule der Gasentla;dung, als, Leuchterscheinung ausgenutzt.Method for recording sound vibrations on photosensitive Materials The invention relates to an advantageous development of the! Procedure for recording, full of sound, vibrations according to patent S35 Sio. In this procedure according to the main patent in an. known way with a capillary Constriction provided as an exposure source discharge, discharge, tube by means of high frequency voltage, which raises the Tänischwungen to be recorded, is molded to glow brought. The positive pillar of the gas discharge is used as a luminous phenomenon exploited.
Es hat sich bei der Verwendung derartiger Lam-1--.en herausgestellt, daß bei geringeren Strominten.-sitäten, des speisenden Hochfrequenzstromesi da,-durch Verzerrungen bei der Aufzeichnung enitstehen, daß die Entladung sich nicht gleichmäßig ausbildet (Schichtenbilldüng). Wesentlich im Interesse einereinwandfreien Leuchterscheinung- ist, daß eine derartige Schichtenbildung innerhalb, d'ex# als: Leuchterscheinung dienenden positiven Gasentla,-dun,gssüule vermieden wird, denn ersti damit ist eine Gewähr für verzerrungsfreie Tolnaufzeichnungen gegeben.It has been found when using such Lam-1 -. En, that at lower Strominten.-sities of the feeding high-frequency currentsi da, -through Distortion in the recording arises that the discharge is not evenly forms (layered budget fertilization). Essentially in the interest of a flawless luminous appearance- is that such stratification within, d'ex # as: luminous phenomenon Serving positive gas discharge, -dun, gssüule is avoided, because only with it is a Guarantee for distortion-free Toln recordings.
Erfindungsgeimäß werden nun bei dem vorliegenden. Aufzeichnungsverfahren Mittel vorgesehen, um irgendwelche Schichtenbüdung innerhaffi der leuchtenden Entladungssäule zu vermeid'en. Diese Mittel bestehen nach einem weiteren Gegenstand der Erfindung darin, daß die in an sich bekannter Weise aus Ouecl<#silberdamp#f und Edelgasgerniisch bestehende Z#asfüllung- von außen erwärmt wird. Es ist dadurch möglich, den im Interesse der Vermeid, ung von. Schichtenbildung erforderlichen Gas.-diuck in der Röh-re genau einzustellen.According to the invention are now in the present. Recording method Means are provided to create any stratification within the luminous discharge column to avoid. These means exist according to a further object of the invention in that the in a known manner from Ouecl <# silberdamp # f and noble gas generic existing filling is heated from the outside. It is thereby possible to do the in the interest the avoidance ung of. Stratification required gas.-diuck to be set precisely in the tube.
Bei den zur Durch£ührung des vorliegenden Erfindungsgedankens; dienenden Entladun#gslampen wird nach einem weiteren Gegenstand der Erfindung der Dampfdruck innerhalb der -Entladungslampe dadurch einreguliert, daß die Lampe von außen durch eine besondere Heizquelle oder durch besonderes Einbetten in Isoliermaterial, wodurch die beim Betrieb der Lampe auftretende Wärme zurückgehalten wird, eine zusätzliche Erwärmung erfährt. Beispielsiweise läßt slich durch eine hinter der Lampe angebrachte Heiz-weadel die Lampentemperatur so weit steigern, daß der erfordeeliche Dampfdruck erzielt wird. Durch Übertemperaturen von :2o bis 3o' wird bereits dieser notwendige Gasdruck erreicht. Reguliert man die Heizung elektrisch, so läßt sich -der' Gasdruck sehr genau einstellen und während des; Betriebes einhalten.In the case of the implementation of the present inventive concept; serving According to a further subject matter of the invention, the vapor pressure is discharge lamps inside the discharge lamp is regulated by the fact that the lamp passes through from the outside a special heating source or by special embedding in insulating material, whereby the heat generated during the operation of the lamp is retained, an additional one Experiences warming. For example, you can see one behind the lamp Heiz-Weadel increase the lamp temperature so far that the required vapor pressure is achieved. This becomes necessary due to excess temperatures of: 2o to 3o ' Gas pressure reached. If the heating is regulated electrically, the gas pressure can be reduced adjust very precisely and during the; Comply with operation.
Der Vorteil des erfindungsgemäßen Verfahrens und der genannten Einrichtungen zur Durchführung desselben besteht daxi.n, daZ es möglich ist, mit der Lampe gemäß dem Hauptpatent mit Sicherheit verzerrungsfreie Ton-aufzeichnuligen, zu erhalten.The advantage of the method according to the invention and the devices mentioned in order to carry out the same it is necessary that it is possible with the lamp according to the main patent with certainty to get distortion-free sound recording.
