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.
MANAGERS AND PROJECTIONS 2X1
ANOTHER FORMULA.— Equal part? of amyl acetate and acetone. Will not turn white on film, and will not dissolve the film as ether will. Works on all kinds of stock. Best used with an all steel 3 flap film mender. Can be used by those making patches by hand if worked properly. Scrape film, use small camel hair brush; keep bottle tightly corked when not in use.
STILL ANOTHER.— One ounce collodion; 1 ounce banana oil or bronzing liquid; Vi ounce ether. For Pathe hand colored films, J4 acetone and V2 ether.
N. I. CEMENT.— For non-inflammable film add 1 part glacial acetic acid to 4 parts of flexible collodion to any of the film cements. It is satisfactory for either N. I. or regular film
FILM REEL CONSTRUCTION.— For many years the weak, flimsy construction of reels worked huge damage to the films the reels were supposed to protect. The earlier practice wa§ to use a wooden hub \l/2 inches in diameter, to which the thin, weak sheet metal sides were attached by means of three or four ordinary wood screws on either side. The hub itself was often made of rather poor wood, its diameter was so small that it furnished little support to the weak metal sides, with result that within a very short time the reels would have bent, crimped sides, and be in more or less wretched condition — condition which actually offered more of damage than protection to the films.
Another fault commonly found was due to the punching out of the sheet metal sides. There was a decided tendency, especially after the dies became worn, for the metal to drag through, leaving a fringe of sharp metal points around the openings in the sides of the reel, and perhaps around its edges too.
In the rush of production, and the insane demand for cheapness in first cost, these rough edges were not ground off, and the points cut and tore the film edges sadly.
Another common source of damage to films by reason of the use of such flimsy reels, was that their bent sides would often rub on the sides of the projector upper magazine, thus acting as a more or less powerful brake, against which the film must pull. This braking action was often so bad, particularly toward the end of the reel, that the sprocket holes would be cracked, or the film actually pulled in two. Also the sides would often be so bent inward
