  Stift zur Herstellung einer Tonaufzeichnung in Berlinersehrift auf einem bandförmigen Lautschrift- träger und Stift zum Abtasten einer solchen   Tonaufzeichnung.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 zur Achse des Stiftes 22  bis 32 , im günstigsten Falle   270 beträgt. Durch Variierung   der Breite 15 des Steges 11 hat man es nunmehr in der Hand, die Tonaufzeichnungsrille des Filmbandes. 1 in verschiedenen Höhen a, b, c abtasten zu können, je nachdem, ob die Tonaufzeichnungsstellen in den Höhen a, b und c schon abgespielt sind oder nicht   (Fig. 3). Wesentlich   ist, dass die Abrundung des Steges 1 immer einen grösseren Radius besitzen muss als die Abrundung zwischen den Prägekanten 7 des Schreibstiftes. 



  Dadurch wird erreicht, dass der Grund der Rille des Tonaufzeichnungsträgers 1 vom Abtaststift nicht berührt wird. Die Abtastung der Tonaufzeichnung der Rille des   Lautschriftträgers 1   wird daher nur an den Punkten   i1-i   vorgenommen, niemals aber über die gesamte Länge der Geraden   i1-f oder g-i.   



  Dadurch wird erreicht, dass die Lebensdauer der Tonaufzeichnung bedeutend   erhöht wird.   



   PATENT-ANSPRÜCHE :
1. Stift zur Herstellung einer Tonaufzeichnung in Berlinerschrift auf einem bandförmigen Lautschriftträger, vorzugsweise einem Kinofilm, dadurch gekennzeichnet, dass an seinem zylindrischen Teil ein Kegel angesetzt ist, der einen Scheitelwinkel von   800 bis 1000 aufweist,   wobei dieser Kegel knapp oberhalb der Spitze zur Erzeugung der Prägekanten einen ebenen Anschliff besitzt und der Winkel zwischen der   Anschliffläche   und der Stiftachse 22  bis 32  beträgt.

 to the axis of the pin 22 to 32, in the best case 270 is. By varying the width 15 of the web 11 it is now in the hand, the sound recording groove of the film tape. 1 to be able to scan at different heights a, b, c, depending on whether the sound recording points in heights a, b and c have already been played or not (Fig. 3). It is essential that the rounding of the web 1 must always have a larger radius than the rounding between the embossed edges 7 of the pen.



  This ensures that the bottom of the groove of the sound recording medium 1 is not touched by the stylus. The sound recording of the groove in phonetic carrier 1 is therefore only scanned at points i1-i, but never over the entire length of straight line i1-f or g-i.



  This means that the life of the sound recording is increased significantly.



   PATENT CLAIMS:
1. Pen for making a sound recording in Berlin script on a tape-shaped phonetic transcription carrier, preferably a movie, characterized in that a cone is attached to its cylindrical part, which has an apex angle of 800 to 1000, this cone just above the tip to generate the Embossed edges have a flat bevel and the angle between the bevel surface and the pin axis is 22 to 32.

 

Claims (1)

2. Stift zum Abtasten einer Tonaufzeichnung, die mit einem Stift nach Anspruch 1 hergestellt ist, dadurch gekennzeichnet, dass dieser Stift einen schmalen Steg besitzt, der unten eine Abrundung aufweist, deren Achse zur Stiftachse geneigt ist und die zur Führung in der Tonrille dient, und dass ein besonderer Schrägschliff an diesem Steg vorhanden ist, dessen Neigung zur Achse des Stiftes 220 bis 320 beträgt.
