What reading level is Sangamo a History of Fifty Years book?
To quickly assess the difficulty of the text, read a short excerpt:
necessary flotation of the armature could be ob- tained by the use of a small cylinder of wood, or composition, attached to the armature disk, instead of which Otis White had gone to much trouble to develop a hollow copper dome, riveted over a raised groove in the disk. This worked fine for a time, but eventually, in many meters, the mercury amalgamated its way through this joint, the float chamber filled with mercury, and the moving sys- 40 Forty Years ofSangamo tern became a "sinker, " as we ...called these after the trouble developed.
Again, as in the case of leaking contact ears a year before, it required only the simple change to a wood float (later replaced by bakelite, as still used) to eliminate the trouble, but, again, we had hundreds of meters out in which armatures eventually had to be replaced.
The worst of this trouble, for some reason, oc- curred in the type "E" alternating current meters, and to a great extent in Texas, probably due to average higher temperatures there which hastened the leakage into the floats.
