Abstracts of Technical Articles from Bell System Sources (01 July 1936)

Another phase of radio with automobiles is the use of broadcast receivers in pleasure cars. Under-the-car antennas, made necessary by introduction of all metal automobile tops, inclusion of the radio control as a part of the instrument board, and the use of circuits for reducing ignition noise are the more important features of 1935 developments. Photons and Electrons.2 KARLK . DARROW . In a book entitled "Biological Effects of Radiation" edited by Professor B. M. Duggar of the University of Wisconsin, Dr. Darrow contributes the first chapter of 42 pages.
