Abstract: A method of automatically realigning a steam generator secondary piping system, such as the feedwater system, in the event of a pipe break to a given steam generator in a system having plural steam generators sharing, in part, a common secondary piping system.

Abstract: A digital spark and dwell ignition control system is disclosed. Maximum advance and reference sensors are utilized to determine positions of maximum and minimum possible advance for spark ignition with respect to the position of the engine crankshaft. For each maximum advance sensor pulse a main counter starts sequentially counting clock pulses wherein the maximum count obtained by the counter is related to engine crankshaft speed. The count of the main counter is utilized by a dwell circuit to determine the time prior to the maximum advance pulse at which spark coil excitation should occur. The main counter count also determines several inputs to a read only memory (ROM) circuit whose output controls a rate multiplier. The rate multiplier receives input clock signals and provides selective frequency division for these clock signals in accordance with the ROM output.
