Description

Es ist bekannt, eine selbsttätige Regelung der Tonstärke bei der Wiedergabe photographisch aufgezeichneter Laute in Übereinstimmung mit einer bei der Aufzeichnung nach Gutdünken vorgenommenen Regelung dadurch zu erzielen, daß man bei der Aufnahme eine zweite, die Verstärkungen und Abschwächungen des Tones bewirkende- Lichtaufzeichnungsreihe auf den Film bringt (deutsches Patent 405 982, britisches Patent 309 208).It is known to have an automatic control of the tone strength during playback photographically recorded sounds in accordance with a control made in the recording at will to achieve that when recording a second, the gains and attenuations brings the sound-effecting series of light recordings to the film (German Patent 405,982, British Patent 309,208).

Es ist auch vorgeschlagen worden, außerdem durch Löcher oder Einkerbungen an den Rändern des Films (britisches Patent 309 208) Kontaktfedern zu steuern, die ihrer-It has also been suggested, moreover, through holes or notches on the Edges of the film (British patent 309 208) contact springs to control the

X5 seits bestimmte Betätigungsorgane auslösen. Jedoch verlangt das eine mühsame und peinlich sorgfältige Behandlung einer jeden einzelnen Kopie:X5 trigger certain actuators. However, this requires painstaking and painstaking care for each individual Copy:

Wo es zweckmäßig ist, außerdem noch andere Betätigungen automatisch zu bewerkstelligen, z. B. Überblendung von Szenen, Aufhellen 'des Saales, eine der Stellung der handelnden Personen in der Szene entsprechende Auswahl aus mehreren LautsprechernWhere it is expedient to also carry out other operations automatically, z. B. Cross-fading of scenes, "brightening up" the hall, one corresponding to the position of the characters in the scene Choice of multiple speakers

as usw., steht eine entsprechende Anzahl von Lichtaufzeichnungsreihen auf dem Film nicht zur Verfügung.as etc., there is a corresponding number of Light recording arrays on the film are not available.

Die Erfindung überwindet diese Schwierigkeiten, indem sie vorschlägt, außer den über das Mikrophon aufzunehmenden Tonaufzeichnungen auch noch verschiedenartige bestimmte infraakustische Wechselströme in dieselbe Tonreihe zu photographieren, die bei der Wiedergabe abgestimmte Relais auslösen, welche die den einzelnen Wechselströmen zugeordneten oben angedeuteten Arbeiten ausführen. Es werden also bei der Aufnahme des Tonfilms von einer Reihe von Tonsendern (z. B. Röhrensendern oder auch einer Wechselstrommaschine, welche verschiedene Perioden abgibt o. dgl.) gelieferte Wechselströme infraakustischer Frequenzen dem in Aufnahme befindlichen Tonstück (Musik oder Sprache) bedarfsweise unterlagert. Bei der Wiedergabe werden diese nicht hörbaren Wechselströme *5 aus dem Tongemisch ausgesiebt und den entsprechenden Relais zugeführt.The invention overcomes these difficulties by proposing, in addition to the above sound recordings to be recorded by the microphone also of various types to photograph infraacoustic alternating currents in the same series of tones that are used during playback Matched relays trigger, which are assigned to the individual alternating currents carry out the work indicated above. So it will be when recording the sound film from a number of sound transmitters (e.g. tube transmitters or an alternating current machine, which emit different periods or the like) supplied alternating currents infraacoustic Frequencies of the piece of sound being recorded (music or speech) as required subordinate. During playback, these inaudible alternating currents * 5 Sieved out of the clay mixture and fed to the appropriate relay.

Die Zeichnung gibt eine beispielsweise Ausführung einer Einrichtung gemäß der Erfindung schematisch an, und zwar istThe drawing gives an example of an embodiment of a device according to the invention schematically, namely is

Abb. ι Schema der Aufnahmeeinrichtung undFig. Ι Scheme of the receiving device and

Abb. 2 Schema der Wiedergabeeinrichtung. Von einer Wechselstrommaschine ι (Abb. 1) für Abgabe verschiedener Perioden gehen die Leitungen 2 bis 6, die verschiedene Frequenzen in dem Intervall von etwa 5 bis 25 Hertz führen, zu dem Transformator 9, während die Schwingungen des Mikrophons 7 über den Vorverstärker 8 und den Hauptverstärker 10 der Aufzeichnungslampe 11 zugeführt werden, die die Schwingungen über den Kondenser 12 auf dem Film 13 aufzeichnet. Wird nun, während z. B. Musik auf das Mikrophon 7 gegeben wird, der Schalter in einer Leitung, etwa 2, niedergedrückt, so unterlagert sichFig. 2 Scheme of the display device. From an alternating current machine ι (Fig. 1) lines 2 to 6, which have different frequencies, go for delivery of different periods in the interval of about 5 to 25 Hertz lead to the transformer 9, while the Vibrations of the microphone 7 via the preamplifier 8 and the main amplifier 10 the recording lamp 11 are fed to the vibrations via the condenser 12 is recorded on film 13. Now, while z. B. Music on the microphone 7 is given, the switch in a line, for example 2, is depressed, it is superimposed

auf Film 13 dem Ton der Musik die Schwingung der Leitung 2 von beispielsweise 5 Hertz. Läuft der Film 13 mit solcher Aufzeichnung (Abb. 2) vor einer lichtempfindlichen 5- Zelle 14 vorbei, deinen Schwingungen, durch 15 verstärkt, über den Ausgangstransformator 16 dem Lautsprecher 17 zugeführt werden, so kommt in 17 auch die unterlagerte Frequenz zum Schwingen; sie wird aber wegenon film 13 the sound of the music the vibration of the line 2 of, for example, 5 Hertz. If the film 13 with such a recording (Fig. 2) runs in front of a photosensitive 5- Cell 14 over, your vibrations, through 15 amplified, fed through the output transformer 16 to the loudspeaker 17, so in 17 the subordinate frequency also vibrates; but it is because of

to ihrer Tiefe vom Ohr nicht gehört.to their depth not heard from the ear.

Auf dem Ausgangstransformator. befindet sich ferner noch die Wicklung 18, die die Schwingungen auch an die Siebketten 19 bis 23 weitergibt. Diese Ketten lassen nur solche Schwingungen durch, die den Frequenzen der Leitungen 2 bis 6 in Abb. 1 entsprechen. Die durch die Siebketten durchgelassenen Schwingungen gehen den Relais 24 bis 28 zu, die verschiedene Schaltungen entsprechend den ihnen zugewiesenen Aufgaben, wie Regelung der Tonstärke usw., vornehmen.On the output transformer. there is also the winding 18, which the Vibrations are also passed on to the sieve chains 19 to 23. These chains leave only such Vibrations that correspond to the frequencies of lines 2 to 6 in Fig. 1. the Vibrations transmitted through the sieve chains go to the relays 24 to 28, the different ones Make circuits according to the tasks assigned to them, such as adjusting the tone level, etc.

Wenn durch Überlagerung der tiefen Frequenzen Störungen, etwa Tremulieren und ähnliche, auftreten, so kann man in die Leitung zum Lautsprecher eine Sperrkette einbauen, welche die infraakustischen Schwingungen vom Lautsprecher fernhält. If, due to the superposition of the low frequencies, interference such as tremulation and similar ones occur, a locking chain can be built into the line to the loudspeaker, which keeps the infraacoustic vibrations away from the loudspeaker.
