Patentirt im Deutschen Reiche vom 6. November 1889 ab.Patented in the German Empire on November 6, 1889.
Phonogramme in der Form von Bändern oder Streifen, welche in einem ihrer Ränder die Schwingungscurve von Lauten oder Tönen darstellen, lassen sich zur Wiedergabe dieser Laute oder Töne benutzen, indem sie zwischen einem Stromkreise, in den ein Telephon eingeschaltet ist, und einem Stromerreger bewegt werden, vorausgesetzt, dafs das Material des Bandes oder" Streifens geeignet ist, die Wirkung des Stromerregers auf den Stromkreis zu hemmen. In solchem Falle wird die Wirkung des Stromerregers nur nach Mafsgabe der durch die Schwingungscurve bedingten Ausschnitte oder Lücken im Rande des Bandes erfolgen können. Um zu erreichen, dafs die Laute einzeln in der ursprünglichen Folge wahrnehmbar werden/ ist das Band in derselben Richtung und mit derselben Geschwindigkeit zu führen, welche ihm bei Herstellung der Schwingungscurve ertheilt wurden, und die Wirkung des Stromerregers ist in jedem Augenblick der Bewegung des Bandes auf je eine Lücke oder einen Ausschnitt im Rande des Bandes zu beschränken. Zur Erreichung des letzteren Zweckes ist erforderlich, dafs zwischen dem Bande und dem Stromkreise eine feststehende Wand mit einem Spalt angebracht wird, dessen Höhe oder Länge der' Höhe oder Tiefe des tiefsten Ausschnittes oder der tiefsten Lück"e in dem Rande des Bandes gleich ist, und das Material der Wand mufs geeignet sein, die Wirkung des Stromerregers auf den Stromkreis neben dem Spalt zu he'mmen.Phonograms in the form of ribbons or stripes running in one of their edges the oscillation curve of sounds or tones can be used to reproduce them Use sounds or tones by switching between a circuit in which a telephone is switched and a current exciter is moved, provided that the material of the tape or "strip is suitable, the effect the current exciter to inhibit the circuit. In such a case the effect will be of the current exciter only according to the details of the sections caused by the oscillation curve or gaps can occur in the edge of the tape. In order to achieve that the sounds individually in the original sequence become perceptible / is the tape in the same direction and at the same speed which were given to him when the oscillation curve was made, and the effect of the exciter is in each one Moment of movement of the tape to a gap or a cutout in the edge of the tape to restrict. To achieve the latter purpose it is necessary that a fixed wall with a gap was placed between the band and the circuit whose height or length is the 'height or depth of the deepest cutout or the deepest gap in the edge of the band is equal, and the material of the wall must be be suitable to the effect of the current exciter on the circuit next to the gap inhibit.
Bringt man vor das Band' mit der Schwingungscurve, dem Spalt gegenüber, eine Lichtquelle und hinter den Spalt eine Selenzelle, welche in den Schliefsungskreis einer galvanischen Batterie eingeschaltet ist, so wird ein in denselben Stromkreis eingeschaltetes Telephon Laute vernehmen lassen, welche den Lauten entsprechen, deren Schwingungen in dem Rande des Bandes dargestellt sind, da die Selenzelle nach Mafsgabe der bezüglichen Schwingungscurve belichtet wird und dementsprechend die Stärke des durch die Drahtwindungen des Telephons fliefsenden Stromes ändert.Bring a light source in front of the band with the oscillation curve opposite the gap and behind the gap a selenium cell, which is in the closing circuit of a galvanic When the battery is switched on, a telephone connected in the same circuit becomes Let sounds be heard which correspond to the sounds whose vibrations in the Edge of the tape are shown, since the selenium cell according to the relevant Vibration curve is exposed and, accordingly, the strength of the wire windings the current flowing through the telephone changes.
Zu demselben Zwecke und in derselben Anordnung lassen sich Wärmestrahlen statt Lichtstrahlen anwenden, wenn man hinter dem Spalt eine Thermosäule, in Stelle der galvanischen Batterie mit der Selenzelle, anbringt.Heat rays instead of light rays can be used for the same purpose and in the same arrangement use if there is a thermopile behind the gap, instead of the galvanic one Battery with the selenium cell, attaches.
Selbstverständlich mufs das Material des Phonogrammbandes und der Wand in dem einen Falle für Licht, in dem anderen Falle für Wärme undurchlässig sein.Of course, the material of the phonogram tape and the wall must be in the one trap for light, in the other trap for heat.
