Description:
Manual of German manufacturer and distributor of projection tools with an emphasis on education. The manual explains the optical laws of how projection works, how to operate diverse projection apparatus – magic lanterns (also called sciopticons or stereopticons), dissolving views, epidiascopes and film projectors. It treats the operation of diverse light sources, the manufacture of slides for projection including several possibilities for adding color. In another part, it explains how to use a magic lantern and projected images in a lantern performance to demonstrate physical, chemical and optical experiments as well as explain special effects achieved by animated slides. In the end (pages 308-319) advertisings of manufacturers of projection devices and accessories are included. To learn more about Ed.

Das elektrische Bogenlicht. 129 nennt das „Kurzschluß“ — so wird die Leitung infolge des ge- ringen Widerstandes plötzlich von einem starken Strome durchfloßen, der bei andauerndem Kurzschluß den Draht über- mäßig erhitzen und durchbrennen würde. Um dies zu verhin- dern, wird an jede Abzweigsleitung eine Sicherung eingeschal- tet; diese besteht im wesentlichen aus einem Stück Bleidraht, der bei einer bestimmten Stromstärke durchschmilzt und da- durch den Strom öffnet. Natürlich wird die Stärke des Blei- drahtes in jedem Falle der Stärke der Leitung derart angepaßt, daß eine zu starke Belastung der letzteren unmöglich gemacht wird. Die Zahl der Amperes, die durchgelassen wird, ist auf die Sicherung aufgeschlagen. Wenn beim Projizieren mit Liesegang, Projektionskunst. 12 . Aufl. 9
