Description
Schallnadel für Sprechmaschinen Schallnadeln für Sprechmaschinen aus den Dornen oder Stacheln von gewissen Gewächsen herzustellen, ist an sich bekannt.Sonic needle for speaking machines Sonic needles for speaking machines To produce the thorns or thorns of certain plants is known per se.
Nach der Erfindung soll nun nicht ein Stachel oder ein Dorn an sich als Schallnadel benutzt werden, sondern das in den Stacheln der Fackeldistel- oder Agavenart der Xerophyten enthaltene Keratin (Hornsubstanz). Zu diesem Zwecke werden die Stacheln oder Dornen einer Behandlung unterworfen, um das Keratin zu isolieren, welches dann gehärtet und mit einem Material überzogen wird, das dem Charakter des Materials entspricht, von dem die Sprechplatten hergestellt werden.According to the invention, a sting or a thorn per se is not intended be used as a sonic needle, but that in the spines of the torch thistle or Agave type of xerophytes containing keratin (horny substance). Be for this purpose the spines or thorns subjected to a treatment to isolate the keratin, which is then hardened and coated with a material that matches the character of the Material from which the speech plates are made.
Die so gebildeten Nadeln für Sprechmaschinen beschädigen oder zerkratzen die Schallplatten nicht, denn sie nutzen sich zusammen mit den Sprechplatten ab, da sie einen ähnlichen Härtegrad haben.Damage or scratch the needles for speaking machines formed in this way not the records, because they wear out together with the speech records, as they have a similar degree of hardness.
Zur Ausführung des Verfahrens wird ein Stachel oder ein Dorn der Agaven- oder Fackeldistelart der Xerophyten zunächst mit einer sehr verdünnten Säure aufgeweicht, um die Fasern weicher zu machen. Dann wird der Dorn etwas angewärmt, d. h. etwa einer Temperatur von 35 bis 5o° C ausgesetzt, und zwar wenige Stunden lang und in einer Lösung oder Mischung getränkt, die als Holzdetektor benutzt wird, z. B. Jodlösung. Im getrockneten Zustande kann man alsdann das Holz leicht von dem Keratin unterscheiden, so daß das Holz sorgfältig von dem Keratin durch Aus- oder Abschneiden entfernt werden kann. Das so vom Holz befreite Keratin wird dann in Alkohol oder Äther eine Zeitlang eingetaucht und hierin entsprechend der Beschaffenheit des Keratins zwischen zwei und vierundzwanzig Stunden belassen, wodurch das Keratin sich verdichtet und erhärtet. Das so geschaffene Keratin wird dann in die erforderliche Form gebracht, um in die Rille der Sprechplatte zu passen. Alsdann wird das Keratin durch Eintauchen oder Besprengen oder sonstwie mit einem Überzug von Harz und Cellulose versehen, welche Mischung durch geeignete Lösungsmittel erhalten wird, um einen vollkommen luftdichten Überzug zu erzielen. Ist das Material vollkommen getrocknet, so wird es in die richtigen Nadellängen zerschnitten, worauf es sich zum Gebrauch eignet.To carry out the procedure, a sting or a thorn of the agave or torch thistle type of xerophytes first softened with a very dilute acid, to soften the fibers. Then the mandrel is warmed up a little, i. H. approximately exposed to a temperature of 35 to 50 ° C for a few hours and in soaked in a solution or mixture that is used as a wood detector, e.g. B. iodine solution. In the dried state one can then easily distinguish the wood from the keratin, so that the wood is carefully removed from the keratin by cutting or cutting can be. The keratin freed from the wood then becomes a in alcohol or ether Immersed for a while and in between according to the nature of the keratin Leave for two and twenty four hours, causing the keratin to condense and hardened. The keratin created in this way is then brought into the required form, to fit into the groove of the speech plate. Then the keratin is made by immersion or sprinkling or otherwise provided with a coating of resin and cellulose, which mixture is obtained by suitable solvents in order to achieve a perfect to achieve airtight coating. If the material is completely dry, it will cut it into the correct needle lengths, upon which it is suitable for use.
Wie bereits oben hervorgehoben, besteht der luftdichte Überzug aus einer Lösung aus Harz und Cellulose. Zusammen mit diesen Nadeln verwendet man Schallplatten, die aus einer Mischung hergestellt sind, welche gleichfalls Harz enthält, so daß in dieser Beziehung das Schallplattenmaterial dem der Nadeln ähnlich ist.As already pointed out above, the airtight cover consists of a solution of resin and cellulose. Together with these needles one uses records, which are made from a mixture which also contains resin, so that in this respect the record material is similar to that of the needles.
