A report on an investigation of a commutated magnetometer detector
(1949)
The subject of this investigation is a commutated rotating coil magnetometer element. One detector with quadrature sets of brushes could be used to align a second element with the total earth's field. It was lay contention ...
An investigation of the catalyzed reaction between methane and steam
(1949)
An investigation was made of the reaction between methane and steam over a reduced nickel catalyst at one atmosphere pressure to form carbon monoxide, carbon dioxide, and hydrogen. Data wore obtained from five-series of ...
A report on an investigation of the change in the natural frequency of quartz crystal oscillators produced by high intensity, long-wavelength x-rays
(1949)
During World War II it was discovered that the elastic constants and hence the natural frequencies of quartz crystal oscillator plates could be changed by radiation v/ith high intensity, long-wavelength X-rays. This discovery ...
A systematic investigation of the lethal effect of high frequency electric fields on staphylococcus aureus
(1949)
A suitable oscillator was designed and constructed to supply the high frequency electric power used In the course of this investigation,. A combination cooler and condenser was used to expose the organisms to the high ...
A wave synthesizer
(1949)
A wave synthesizer has been constructed that converts a 60 cycle saw-tooth input into an output consisting of either 120 cycle, 300 cycle, or 600 cycle sine wave (the second, fifth, and tenth harmonics of 60 cycles), or ...
An investigation of polyphase machinery from a consideration of magnetic energy
(1949)
Statement of Problem: The purpose of this paper is to develop torque formulas for polyphase machinery from a consideration of the energy change in their magnetic fields due to a displacement of the magnetic axes of the ...
A survey of geophysical prospecting methods
(1948)
Existing geophysical prospecting methods were studied with the emphasis on reflection seismic practices. From the wave equation, the derivation of the transmission and reflection coefficients for plane polarized waves in ...
