Cochran Chieftain Mark 4 Steam Boiler Control System Revised Design and Construction

Abstract

In this paper an attempt has been made to show how problems created by machinery can be solved locally and expeditiously using innovative and adaptive approaches. The technologies used were appropriate and easily understood. A timer control system and an electronic switch have been designed and constructed entirely from locally available materials to replace and improved malfunctioning one. The reliability of the locally designed and constructed one is high. It is still functioning one year after it was installed and tested. Transistors, pneumatic timers and conductors were used.
