Otis King Cylindrical slide rule
The Otis-King rule uses concentric telescoping metal cylinders with a
continuous long spiral logarithmic scale. Calculations are done by
sliding and rotating the cylinders relative to each other. The purpose
of using a cylinder design slide rule is to increase the length of the
scales, thereby improving the accuracy, relative to the linear type.
