A Cylindrical Sector Driven by Either Water or Air

Abstract

The cylindrical sector designed by Yuster1 is more compact and simpler in construction than the disk sector. A further development is a cylindrical sector driven by either water or compressed air in place of the usual electrical motor. It is designed to operate in either the water system for cooling the electrode holders, or in the compressed air line circulated from a central location in the laboratory building. The term sector defines the rotating disk or cylinder that controls the gradient of the light illuminating the spectrographic slit. Each gradient desired (step, log function, intensity reduction, etc.) requires a different sector design. A small air turbine driven step sector is described elsewhere.2
