 Ten-Stage CoJd-Cathode Stepping Tube, Elec. Eng., 71, pp. 1136- 

 1139, Dec, 1952 (Monograph 2054). 



Developments in the art of transferring a gas discharge from one point to 

 another in a multi-electrode tube have led to the design of a 10-stage counting 

 tube operating up to about 2,000 pulses per second. Such a tube can be used 

 for pulse counting, frequency division, time measurements, and similar 

 functions.

 Information-Bearing Elements of Speech, J. Acoust. Soc. Am., 24, 

 pp. 629-637, Nov., 1952. 



This study deals with those aspects of speech which are phonetically signifi- 

 cant. A technique has been developed with which phonetically equivalent 

 speech samples may be obtained in different phonetic contexts and from 

 different speakers. Data on two front vowels by different types of speakers 

 are presented. The technique has also been appUed to the evaluation of words 

 containing these two vowels.

 New Method of Calculating Microwave Noise in Electron Streams, 

 I.R.E., Proc, 40, pp. 1675-1680, Dec, 1952. 



The noise in a temperature-limited electron beam in a drift space is calculated 

 by a new means. Noise maxima and minima are found. The results agree 

 with calculations made by the Rack-Llewell^m-Peterson method.

 Statistical Fluctuations of Radio Field Strength Far Beyond the 

 Horizon, I.R.E., Proc, 41, pp. 274-281, Feb., 1953. 

 When a sinusoidal radio wave of extremely high frequency is sent out by a 

 transmitter, the wave received far beyond the horizon is often observed to 

 fluctuate. Here some of the statistical properties of this fluctuation are derived 

 on the Booker-Gordon assumption; namely, that the received wave is the 

 sum of many Uttle waves produced when the transmitter beam strikes "scat- 

 terers" distributed in the troposphere. Expressions are obtained for the 

 periods of the fluctuations in time, in space, and in frequency. These expres- 

 sions extend closely related results obtained by Booker, Ratcliffe and others.
