Ments employing frequency division techniques by which the telephone message-carrying potentialities of the coaxial cable system are realized.
Which shows that the "normal" substitution voltage equals the open circuit voltage for all types of acoustic measurements and for any value of electric impedance loading the microphone.
that, for any given class and length of pole, all six species are equal in strength.
1. During "all-daylight" path conditions, the usual multiplicity of waves distributed in or near the great-circle plane, which constitutes normal propagation, has been predominant.
This paper describes briefly the voltage and current relations, preliminary tests on a small-scale rectifier, the phase shifting transformers and their application to this particular situation, and

Quently, copious references to the experimental results of other workers have been included.
The changes in emission from a coated filament produced by changes in plate potential and by currents sent into or drawn from it, are ascribed to electrolysis of the oxide.

A new high vacuum pumping system is described in which oil is used in a diffusion type pump, and a trap containing activated cocoanut charcoal replaces the usual liquid air trap.
