Saturday's fray was marked by the air-tight playing of both teams. In the first half they battled on nearly even terms, but in the second period Falcon Club managed to pierce their opponents' defense to score the winning goals...
...primary cause of cables breaking down in service is due to the fact that small voids or air spaces are formed within the paper insulation. With present methods of manufacture, these voids appear to be inevitable. When such voids form, a minute electric discharge takes place within the void; that is, small electric arcs form, and the molecules of air find themselves in an electric field which causes them to attain high velocities. This effect is called ionization. The ions then impinge on the paper and oil, and have the effect of a rapid and continual bombardment. They not only...
...extremely high voltages, with very great precision. By means of the bridge, we are determining the electric properties of oils and papers at different temperatures and frequencies, and under different conditions of impregnation. Also, we are investigating the electrical characterisics of the electric discharges which take place in small air spaces...
...have already determined some of the essential electrical properties of these ionized gas films. With this information, we have been able to determine from simple power measurements on a cable just how much power is being lost as ionization in the destructive air films. Naturally, the life of the cable is associated with the amount of this loss. Experiments have shown that cables which have the highest value of this ionization loss also appear to be the poorest cables. A paper on this subject was presented at the last Midwinter Convention of the American Institute of Electrical Engineers...
...roar of the ventilating apparatus in the upper lecturer room and the Library is so loud as to prove a distraction in the latter and even to drown out a low-voiced lecturer in the former, while the air in the upstairs room seems to benefit not at all from the uproar when a large course such as Fine Arts 9a is in session...
