The Carter system, also known as the Chicago system, was a method of wiring three-way switches in the era of early knob-and-tube wiring. This now-obsolete wiring method has been prohibited by the USA National Electrical Code since 1923, [ 2 ] even in new knob-and-tube installations which are still permitted under certain circumstances.
The ARC-210 program began in 1990 as an improved version of the AN/ARC-182, adding jam-reisistant SINCGARS capability to communicate with Army radios for close air support. [2] The Arc-210 is installed on more than 180 platforms and is operating in more than 40 countries. As of 2010, 30,000 have been produced [3] and by October 2016, 40,000 ...
The Viking model was born out of discussions at Downer for a bigger version of the "Model 260" with at least 300 horsepower. The company was based in Minnesota and employed skilled craftsmen who manufactured the wing from spruce, and the new 300 hp model was named the "Viking" in respect to the many Scandinavians of the area.
DBL has an English-like syntax that was designed to be self-documenting and highly readable, but not verbose. The language is procedural and, since 2007 (version 9.1), object-oriented. [1] Support for Microsoft’s .NET Framework was added in 2010 (version 9.5). [2] Code is split into two divisions (data and procedure) and uses a rigid hierarchy.
The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine.
