摘要:
A ``zigzag'' type of spring for supporting current‐carrying filaments is described and compared with the tungsten helical type of spring. The zigzag spring is particularly useful when a combination of high current‐carrying capacity and low spring constant is desired. Designs and stress analyses are deduced both for the helical and the zigzag spring, to meet a wide range of requirements. An approximation is given for the elastic limit of molybdenum and the rolling and annealing of molybdenum sheets for tube parts are discussed.

摘要:
A generating voltmeter type automatic electric field recorder designed for continuous measurement of surface electric fields in thunderstorms is described. The performance of the instrument in the field under thunderstorm conditions is discussed. The application of this instrument to the study of the normal potential gradient of the earth is suggested.
