Sorption-desorption properties of dual oxide gels in the system BeO-In_O3
Water vapor sorption-desorption isotherms at 2° and 12° have been obtained for a series of eleven heat-treated (2 hour periods) gels selected at every 10 mole per cent in the system Be0-1n203. Two zones of enhanced adsorption ...
On extending audio feedback loops to include electrodynamic speakers
Summary. The purpose of the investigation was to determine the applicability of extending inverse feedback techniques to electrodynamic loudspeakers by finding first, what the general limitations were, and second, how much ...
The ultrasonic measurement in nitrogen, carbon dioxide and nitrogen-carbon dioxide mixtures at medium pressure and temperature
Velocity of sound measurements have been made in pure nitrogen, pure carbon-dioxide and mixtures of these two gases at a constant pressure of 50 psi over a temperature range from 75°F to 530°F. From the experimental data ...
A neighborhood unit
When World War II broke out in 1941 many housing projects were erected to provide living accommodations for war workers. In most cases these developments were constructed under an accelerated program that could accommodate ...
