I work with a pair of Kinoton 35mm projectors at UC Irvine in So. California. They are made in Germany and the manuals and data plates are in German. I've had to learn a few new words: [Linked Image]

Tonformatumschaltung = Sound Format
Projektoren = Projector
Bildformate = lens format (?)
Objektivrevolver = lens turret
Bildmaskenwechslern = aperture changer
Xenonkurzbogenlampe = Xenon lamp (I may have that spelled wrong..)

(All above come from the translations in the service manuals.)

There's more, but you get the idea. It has been quite educational.

Stupid should be painful.
