The need for improvements in scattered x‐ray spectroscopic technique along the lines of increased intensity and contrast is discussed and a new instrument composed of fifty small units, each a Seeman Spectrograph in itself cooperating to form a single spectrogram, is described in detail. The...
It is pointed out that the ordinary Toepler‐Holtz static machine is the two‐symmetric member of a whole family of poly‐symmetric static machines of the same general type, in which the number of symmetries (or inductors) can be both even and odd. Historically only the even‐symmetric...
When radiation is allowed to pass alternately through one and the other of two filters having identical transmissions for all wave lengths except those lying in a narrow spectral region, a flicker is produced which is a function of the intensity of the radiation within that region. A radiometer...
