APPENDIX Motion picture projectors, screens and accessories are not discussed in the body of this book. Portable Projectors For classroom teaching a portable projector is essential. Even if the school has already bought a big theater type machine for permanent installation in an assembly room, the portable classroom projector is needed for showings in the several classrooms. A good reliable portable can be had, weighing only twenty-five pounds. As these are light enough to be carried easily by a teacher or pupil, and can be attached to any light socket in the room, they will be used ten times to every once of the big machines. With these machines and daylight screens, pictures of professional quality can be shown in only a semi-darkened room. A student or teacher can be taught in a half hour to operate these machines. The projectors should handle film of full standard professional size (35 millimeters) such as is used in theaters, so that the whole world of motion pictures may be available. Off-standard or narrow width machines are limited to the special films made of that size for those special machines, or else special production prints from the standard negatives, and the illumination is insufficient for classrooms and assembly rooms. Up-to-date portable and semi-portable projectors are supplied with a stop-on-the-film shutter which, if the shutter is of the proper kind of glass, permits the teacher to stop on any picture for several minutes, without danger.
