Description
V'ecschlussscheibe für Kinematographen. Um die - Blendung des Auges erzeu gende - Kontrastwirkung beim Öffnen und Schliessen des Verschlusses und eine daher nötig werdende Steigerung der Lichtstärke zu vermeiden, hat man bereits vorgeschlagen, die Verschltissscheibe für Vorführungs-Kine- matographen mit gefärbten, durchscheinen den Flügeln zu versehen. Versuche haben er geben, dass eine besonders günstige Wirkung dann erreicht wird, wenn die Flügel in Farb- sektoren unterteilt sind, die sich für jeden einzelnen Flügel annähernd zu weiss ergän zen.
So kann man zum Beispiel jeden Flügel in vier gleich breite Kreisausschnitte zer- legen, von denen je einer rot, grün, blau und weiss ist.
Closing disc for cinematographs. In order to avoid the - dazzling of the eye generating - contrast effect when opening and closing the shutter and a consequent increase in light intensity, it has already been proposed to provide the wear disc for demonstration kinematographs with colored, translucent wings. Tests have shown that a particularly favorable effect is achieved when the wings are divided into color sectors that are almost white for each individual wing.
For example, each wing can be broken down into four circular sections of equal width, one each of which is red, green, blue and white.
