Side xii - The total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the gases in the mixture.
Side 184 - Without interrupting the current, siphon off the acid solution, at the same time filling the beakers with distilled water. Remove the cathodes quickly and rinse them in distilled water and two successive baths of alcohol. An experienced operator can quickly remove a cathode and immerse it in water without loss. Throw off the excess alcohol by a quick motion of the hand and ignite the remainder by bringing the cathode quickly to the flame of an alcohol lamp; then keep the cathode moving continually...
Side 280 - C. require larger proportions of air to gas; however, a strongly reducing atmosphere is not so essential at the higher temperatures, as refractory ashes, owing to their low iron-oxide content, are only slightly affected by oxidizing or reducing atmospheres. After a test has been completed, turn the supply of gas and air off gradually to avoid cracking the muffle crucible. The softening temperature is...
Side 279 - While such a flame is maintained above the furnace, gradually increase the temperature by a suitable adjustment of gas and air to 800° C., then reduce the rate of heat increase to not less than 5° C. and not more than 10° C. per minute. Maintain this rate until the end of the test. It is also important that the 6-in.
Side 279 - Fig. 2, place the loosely fitting cover g on the crucible, and ignite the gas. It is necessary to let the gas burn about 10 minutes to heat the furnace parts before the large cover plate of the furnace is replaced; otherwise the flame is apt to blow out. During this time increase the flow of gas and air sufficiently to cause the combustion to take place just above the tuyeres and yet maintain a yellowish flame at least 6 in.
Side 277 - ... from the top of the cylinder (excluding cover plate), and a 1-in. thermocouple hole 90 deg. to the right of the observation hole; the bottom of these two holes being in the same horizontal plane. The interior of the furnace is cylindrical and approximately 7 in. in diameter and 1 1 in.
Side 278 - ... the bottom of the crucible, and a thermocouple hole 1 in. in diameter, 90 deg. to the right of the observation hole. The bottom of this hole should be in the same horizontal plane as the bottom of the observation hole.
Side 264 - After the more rapid discharge of volatile matter has subsided, as shown by the disappearance of the luminous flame, tap the cover lightly to more perfectly seal the crucible and thus guard against the admission of air.
Side 264 - C. ± 20° C. in the crucible, as shown by a thermocouple kept in the furnace. If the determination of volatile matter is not an essential feature of the specifications under which the coal or coke is bought, a Meker burner may be used. Method For Coal and Coke, Usual Method : Weigh 1 g.
Side 415 - HC1, evaporated nearly to dryness, taken up with cold water, and any residual matter is filtered off. The solution is then boiled with oxalic acid until the gold is all precipitated. It is well to let the solution stand overnight before filtering off the gold. The gold is filtered off and the platinum, recovered by boiling the solution, which has first been neutralized with sodium carbonate, with formic acid, is then filtered off, ignited, and its weight added to that of the platinum already found....
