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.
MENDING THE FILM FINDING DEFECTS IN THE FILM Defects in a film, which call for mending, or for cutting and joining are looked for on a rewinding machine. The film is rewound, and as it passes from one reel to the other, it is passed through the fingers of one hand. Rough spots, where the film has been badly joined are easily detected by the feel; a joining, which is on the point of giving way is thus found. MENDING A FILM A joining should be so done as not to throw a single picture out of phase. This does sometimes occur, when the mending has been done by an incompetent or careless person. This defect is not found by feeling, and it is very hard to find by sight in the rewinding. To mend a film it is necessary to sacrifice one picture. The film is cut through, using a straight edge or ruler, exactly on the edge of a picture. The other piece of film is cut through between the first and second holes and midway between them. The straight edge is now placed across the second piece of film, exactly on the edge of the picture, and the film outside the ruler is moistened with water, put on with a camel hair brush. This will soften the film, so that it can be rubbed off with a bit of rag, after the film has been cut through along the edge of the straight edge. This cut must be only enough to cut through the film, and the lightest possible pressure on the knife may be quite sufficient. A coating of film cement is now applied to the surface just cleaned, and it is quickly placed on the celluloid side of the other piece of film, and it is placed with the holes in exact register, one over the other. A tapering stick of wood, or better a metallic pointed wire or slender rod, like a scribe awl, may be used to insert in the two holes, first on one side and then on the other, to ensure their being in perfect correspondence and one on top of the other. The teeth of the sprockets have to go through every hole on the film, so it is absolutely essential that the two holes should correspond. A film mender is a little press which holds the film in per- fect registration as it is drying, and pressses the pieces together as they dry, so as to produce a flat mend. 255
