Page 290 - Lulled in the countless chambers of the brain, Our thoughts are linked by many a hidden chain. Awake but one, and lo, what myriads rise ! * Each stamps its image as the other flies.
Page 128 - In this pyrometer the radiation which emanates from a hot body, or which passes out through an observation hole in the wall of a furnace, falls upon a concave mirror and is thus brought to a focus. In this focus is a thermo-electric couple, whose temperature is raised by the radiation falling upon it ; the hotter the furnace, the greater the rise of temperature of the couple.

The Titus Sheard Company was indebted to the knitting company and, upon the insolvency of the latter, it took up the paper which it had indorsed and discounted with the bank, and set it off against its debt to the knitting company.

About one-half of the fluorspar purchased by this company does not contain over 5 per cent. silica. In the making of open hearth steel castings the function of fluorspar is to thin a limey slag when in the judgment of the melter it seems thick or sluggish. A moderate addition of fluorspar will liven it and its action may be likened to certain fluxes used in brazing...

Page 188 - Therefore 4.26 parts of calcium fluoride are necessary to flux 2.73 parts of silica in the coke. "Since there are 82.28 lt>s. available CaF2 in one hundred pounds of fluorspar; then 82.28 : 100 : : 4.26 : x =5.18 pounds; or 5.18 lbs. of fluorspar are necessary to flux one hundred pounds of coke. "The amount needed to flux the sulphur and the sand on the iron, may be gone through in a similar manner.
