Not illustrated. 1917 edition. Excerpt: ...and Its Applications." 1915, page 168. interesting aspects of reflection and of colors are touched upon to show how intricate the reflection of radiant energy is and as a consequence the measurement of reflection factor. The author acknowledges the assistance of H. H. Kirby in obtaining the data and making the illustrations for this paper. Characteristics of Standard Inclosed Fuses--II Results of an Investigation of Suitable Construction Materials, Performance of Fuses Under Different Operating Conditions, and Effect of Size, Kind and Amount of Filler on Operation By Walter Arthur 0 10 20 3Q 40 50 60 70 60 90 100 110 120 Time Seconds nO. 3--CURVES SHOWING EFFECT OF INITIAL TEMPERATURE ON TIME OF FUSE BLOWING standard inclosed fuses, are taken up the effect of length, diameter and heat conductivity of the fuse case, location of the fusible element, temperature of surrounding air, initial temperature, indicator wires, etc. Considerations necessary in testing fuses are also pointed out in this article. The heat conductivity of the inclosing case has an influence on the time-blowing of fuses, but no data are at hand to enable the determination of the relative conductances of cases of different materials. It is obvious, however, that a wholly metal or porcelain case would conduct heat more rapidly than fiber cases. A greater conductance would tend to increase any errors due to this cause. The same may be said to be true of heat capacity. The length and diameter of the fuse case is of considerable significance in so far that there is a certain minimum length and diameter beyond which we can go without materially affecting the results. At the same time there is a certain maximum length and diameter beyond which we cannot hope to go and...show more
