Description
Selbsttätiges Umschaltgetriebe; Zum Umsteuern von kinematographischen Vorführungsapparaten.Automatic change gear; For reversing cinematographic Demonstration machines.
Zusatz zum Patent q.17590. Die Erfindung betrifft eine Anwendungsform des selbsttätigen Umschaltgetriebes nach Patent q.17590.. Bekanntlich ist, während der Film bei der Vorführung abrollt, die Lichtquelle eingeschaltet, welche das Bildband durchleuchtet und das Bild auf der Projektionsfläche zur Erscheinung bringt. Wird nun der Film mit der den Gegenstand des Patents q.17590 bildenden Vorrichtung auf Rücklauf umgesteuert, dann ist während dieser Zeit die Lichtquelle ausgeschaltet, es würde also während des Rückrollens die Projektionsfläche unbeleuchtet bleiben.Addition to patent q.17590. The invention relates to an application form of the automatic changeover gear according to patent q.17590 .. is known while the film unrolls during the screening, the light source switched on, which is the illustrated book is illuminated and the image appears on the projection surface. Will now the film with the device forming the subject of patent q.17590 Return reversed, then the light source is switched off during this time, the projection surface would therefore remain unlit while it is being rolled back.
Nach der Erfindung soll diese Zeit für Vorführungszwecke dadurch ausgenutzt werden, daß im Moment der Umsteuerung auf Rücklauf der Kippschalter eine Lichtquelle einschaltet, die ein stehendes Bild auf der Projektionsfläche zum Erscheinen bringt, und die wieder selbsttätig ausgeschaltet wird, sobald der Schalter bei Umsteuerung auf Vorführung zurückkippt.According to the invention, this time is to be used for demonstration purposes be that at the moment of reversing the toggle switch to reverse a light source switches on, which brings a still image to appear on the projection surface, and which is automatically switched off again as soon as the switch is reversed tilts back on demonstration.
