It is a coupling device used to secure two adjacent cylindrical segments of a pressure vessel common in tactical rocket motors. The key is made of elongated rectangular metal bar stock, such as steel, and is inserted into juxtaposed annular grooves around the circumference of the mating parts. An Edmund key also provides a feature at the end of the key to allow the key to be extracted from the groove for disassembly. == Sources == Patent number: 6729004 Nov 13, 2002 == References == - [[Environmental Design/Energy Efficiency]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 04 - Fire and Life Safety]] - [[Interior Architecture/Renovation and Conservation/Building Assessment]] - [[History and Theory/World History/Ancient Architecture]] - [[History and Theory/Vernacular]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 2 - Soils and Foundations]] - [[Design/Building Typologies/Healthcare Architecture]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 09 - Plumbing Services/Section 2 - Drainage and Sanitation]] - [[Environmental Design]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 10 - Landscape and Signs/Section 2 - Signs and Display]]
