Pliodynatron (exctract)

The Pliodynatron by Dr. Hull of General Electric is mentioned in the book "Radio Telephony", written by Alfred N. Goldsmith (fellow of the 'Institute of Radio Engineers', member of the 'American Institute of Electrical Engineers', director of the 'Radio Telegraphic and Telephony Laboratory' and professor at 'The College of the City of New York') , issued in 1918 at 'The Wireless Press, Inc., New York).

I have extracted the Pliodynatron related pages 102 and 174 to 181, even if there is a mixture between Pliodynatron and Pliotron (in general, see also CA_Pliotron, G_Pliotron, P_Pliotron and later U_Pliotron) and Dynatron.

The chapters are

• Pliodynatron Construction (page 102)
• Hull's Pliodynatron Modulation Control (page 175)
• Modulation Characteristics of Pliodynatron (page 176)
• General Electric Company Pliodynatron Radiophone (page 177)
• Effect of Internal Bulb Coupling (page 179)

Enjoy!

May I add that according to Tyne, "Saga of the Vacuum Tube" (p.146, fig.8-14 and 8-15) Dr.Albert W.Hull had sent a paper to the I.R.E., where he described both his Dynatron and the Pliodynatron. (Proc. I.R.E., 1918, 6).
