Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ... (s) armature; (t) steel valve chamber; (u) plunger with rubber washer and mercury seal working against end of gas-supply pipe (v) and wired to armature (s); (w) needle valve to regulate size of pilot flame; (x) micro-burner with needle valve; (y) gas-cocks to relay and rough heater (z); (zz) high-voltage lamp spanning spark-gap of thermostat. D. Stirring mechanism: (aa) Shaft; (bb) Q-shaped bracket; (cc) oil cups and bearings; (dd) pulley with oil trap filled with waste; (ee) oil trap; (ff) six-bladed propeller. E. Cooling system: (oo) Standpipe; (hh) supply; (n) overflow; (jj) petcock in cap; (kk) regulating valve to coils; (i.i, ) inlet pipe to coils; (mm) interchangeable unions (here ice or hot water coils may be inserted for very low or high temperatures); (nn) cooling coils; (oo) waste pipe. F. Diagram of top (smaller scale): (b), (d), (f), (h). (j), and (k) the same as in A; (mm) same as in E; (it) aper tures in cover for conductivity cells; (qq) lugs supporting cover; (rr) handle to removable section of cover. The acetone was dried over calcium chloride for at least a week before using and was then redistilled several times immediately before making up the mixed solvents. It had a mean specific gravity of 0.787 at 25, and a specific conductivity of about 4X10"7 at that temperature. The conductivity water was obtained by the method of Jones, McKay, and Schmidt, and had a mean specific conductivity of 1.5X10 at 25. The mixed solvents were prepared by mixing one or two parts of each of the above components with varying proportions of the other two. Seven such combinations proved to be possible, and were prepared for solvents in one-liter quantities immediately before using. The specific data relating to each solvent are to be found in...show more
