What reading level is Radiotelegraphy U S Signal Corps 1914 book?
To quickly assess the difficulty of the text, read a short excerpt:
In some cases it may be possible to mount the alternator and gap so that short leads can be brought out from the latter through well-insulated bushings into the next room, which should be sound proof, and thus all the circuits be contained in the same room with the operator for convenience and promptness in making changes in wave length and other adjustments, etc. .
QUENCHED SPARK GAPS.
Most modern sets use the quenched spark gap, a brief description of which will be given here and the theory o...f the quenched spark transmitter later. The gap is essentially a series gap consisting of a number of plates with small separations between the sparking sur- faces, which are inclosed in air-tight chambers formed between the plates themselves.
40 KADIOTELEGRAPHY.
In figure 33 is shown a section of a gap where P are the plates often made of copper, which, on account of good conductivity for heat, will carry off the heat of the spark; F are the flanges, which help the cooling by exposing a large area to the air or to the air blast to be mentioned later; S are the sparking surfaces between which the sparks pass, which may be of the same copper stock as the rest of the plate or of heavy silver plate fastened in place at S; M the separators or insulating rings, also called gaskets, between the plates, often made of mica, about 0.
