Abstract: Exemplary methods and systems for a distributed control system (DCS) in an industrial environment such as a plant. The DCS includes sensors for monitoring plant processes, and controllers for controlling plant processes. The sensors and controllers each have an associated communication protocol. The DCS also includes an interface that receives data from the sensors, translates the data into a common protocol, and generates control signals based on the translated data to the controllers over a network. The interface communicates with each sensor and controller based on their respective communication protocols.

Abstract: An apparatus and method for connecting bimetallic members by explosive bong. The apparatus comprises a bimetallic collar having an outer aluminum ring and an inner steel ring that are connected by explosive bonding. The steel fitting is welded to the steel ring and the aluminum ring is welded to the aluminum deck. The method of making the bimetallic collar is by vertically and concentrically mounting an inner solid steel cylinder, an intermediate hollow aluminum cylinder, and an outer cardboard cylinder and thereby forming an annular acceleration cavity between the steel and aluminum cylinders and an annular powder cavity between the aluminum and cardboard cylinders. The annular powder cavity is filled with powder and ignited. The explosion causes the aluminum of the aluminum cylinder to accelerate across the acceleration cavity and become bonded to the outer surface of the solid steel cylinder.

The solid steel cylinder is then bored out leaving an aluminum cylinder explosively bonded to a hollow steel cylinder.
