We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

reel — The flanged spool upon which film is wound for use in projecting machines. reel — An arbitrary unit of measure for film — approximately a thousand feet of length. rewind — The process of reversing the winding of a film, usually so that the end to be first projected shall lie on the outside of the roll. rewinder — The mechanism by which rewinding is accomplished. safety shutter (also known as the fire-shutter) — The automatically operated door (in a projecting machine) which intercepts the light when the machine runs below normal speed. screen — The surface upon which a picture is optically projected. shutter — The obscuring device, usually a segmental revolving disc, employed to intercept the light during the movement of the film in motion picture apparatus. shutter — working blade (also known as the cutting blade or obscuring blade) — That segment which intercepts the light during the movement of the film at the picture aperture. shutter — intercepting blade (also known as the flicker blade) — That segment which intercepts the light one or more times during the rest or projection period of the film. sprocket — The revolvable toothed member (in motion picture mechanisms) which engages the perforations in the film. take-up (verb) — The process of winding the film (in a motion picture machine) after it passes the picture aperture. take-up (noun) — The mechanism which receives and winds the film (in a motion picture machine) after it passes the picture aperture. throw — The distance to the screen from the objective of a lantern or a motion picture projecting machine. still — ^A picture printed from a single negative.
