摘要:
The rotary voltmeter is shown to be a practical instrument for the measurement of both voltages and wave forms up to 830 kilovolts peak. A comparison of voltages so measured with the sphere gap shows that a downward revision of the A. I. E. E. standards is necessary.

摘要:
A two‐stage oil diffusion pump built of glass is described which makes possible the utilization of the advantages of oil without requiring the use of an unusually good coarse vacuum. The novelty of the pump resides in the first stage which is so designed that it cannot clog even with the small clearances needed to work against high pressures.

摘要:
A very general method is given for the calculation of lattice constants from powder photographs in which there is taken into account the various systematic errors inevitable in such photographs, including radius errors, film shrinkage, absorption, eccentricity and finite slit height. While the solution of the data is made by least squares, it is not at all laborious and is much simpler than the various methods, both analytical and graphical, which have previously been proposed. Examples are given of cubic, hexagonal and orthorhombic structures solved in this way using data from Debye and focusing cameras, extension to other structures and cameras being made evident. In effect, powder cameras become absolute instruments, independent of calibrating substances, and dependent only on the value of the x‐ray wavelength.
