Abstract

Mejoras aplicable a los aparatos de proyección cinematográfica de desarrollo continuo de la película que permiten la proyección de películas de uno o de varios tamaños en el mismo aparato caracterizadas porque la reducción de la imágen de la película en una o varias veces se efectúa por dispositivos ópticos convergentes que están constituídos con preferencia por varias lentes con objeto de dar una imágen reducida perfecta.Improvements applicable to cinematographic projection apparatus of continuous film development that allow the projection of films of one or several sizes in the same apparatus characterized in that the reduction of the image of the film in one or more times is carried out by optical devices convergent which are preferably constituted by several lenses in order to give a perfect reduced image.
