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.
138 MOTION PICTURE HANDBOOK many operating rooms. The average foot shutter you will find attached to the shutter by a scrap of wire—often two or three pieces of wire patched together. The pedal will be a little piece of board about 4 by 8 inches, attached to the floor by a strap hinge, which, in nine cases out of ten, is partly or wholly loose. Do things right, or get out and give someone the job who will! One of the Jirst things my father taught me was "if a thing is worth doing at all, it is worth doing well." The longer I live, the more firmly I am convinced that the old gentleman was absolutely right. The "Oh, that's good enough!" workman is a miserable failure at any- thing he undertakes. The "Oh-that's-good-enough-I'll-do- just-as-little-as-I-can-and-keep-on-the-payroll" man is not an operator, or much of anything else, for that matter, no mat- ter how much he may know. In fact, it is not what you know that counts, but what application you make of your knowledge. To be a real operator you must not only know, but you must also do. Wages are too low, I am well aware, but when the writer gets to the point where he doesn't feel ambitious enough to do his work right, owing to low wages or anything else, he will quit, and he will do it very suddenly, too. There is absolutely no excuse under the heavens for doing things any other way than right. THE ELECTRIC METER. The meter is a very simple affair, consisting of a small motor which actuates the pointers to the dail by means of a train of gears. This motor is placed in the series with the lamps or motors using the current passing through it. The motor is so constructed that if it were operating under a pressure of one volt, with one ampere of current flowing, it would require, under those conditions, precisely one hour to record one Watt, which would, therefore, be one Watt hour. It, therefore, follows, that if it were working under a pressure of no volts with one ampere of current flowing, the Watts being the product of the volts times the amperes, the instrument would record no Watts in one hour; or if the pressure be one volt with no amperes flowing, the rec- ord for one hour would be no Watts. If, on the other hand, 30 amperes were flowing under a pressure of no volts, then
