Abstract
The use of the North American Philips spectrometer for the radial and azimuthal scanning of the transmitted x‐ray diffraction of rayon tire yarns involved a change in the slit system from convergent to divergent, design of a rotating sample holder, a reproducible sample preparation and positioning, and calibration and control checks which guarantee that the x‐ray intensity remain constant to ±2 percent as automatically recorded by the rate meter. Typical data are presented and compared with data obtained photographically.
