Сторінка 515 - With naked open fuses, of ordinary shapes and not over 500 amperes capacity, the maximum current which will melt them in about five minutes may be safely taken as the melting point, as the fuse practically reaches its maximum temperature in this time. With larger fuses a longer time is necessary.
Сторінка 349 - ... generators it is also likely to cause flickering in the lamps. In lacing belts, the ends should be cut perfectly square, and there should be as many stitches of the lace slanting to the left as there are to the right; otherwise the ends of the belt will shift sidewise, owing to the unequal strain, and the projecting corners may strike or catch in the clothing of persons.
Сторінка 519 - When incandescent lamps are used for decorative purposes, as in the use of miniature colored lamps, and it is necessary to run two or more in series, permission should always be secured, in writing, from the Inspection Department having jurisdiction. Arc Lamps should be carefully isolated from inflammable material, should be provided at all times with a glass globe surrounding the arc and securely fastened upon a closed base. No broken or cracked globes should be used, as they are designed to prevent...
