"Throwing The Book" At The Regulator. "Regulations" are regular for the "Quick Flash Flasher Regulator" — which means that these nerve center gadgets of the flashing buoys are allowed no lee-way in accuracy. These regulators or valves, which the students in this photo are timing so carefully, are adjusted on the split-second, so that the six flashes, each of two-tenths of a second duration, are spaced at six-tenths of a second intervals, with an "eclipse" of six-tenths of a second between. These flash groups, or cycles, are separated from each other by an "eclipse" of four and two-tenths of a
"Throwing The Book" At The Regulator. "Regulations" are regular for the "Quick Flash Flasher Regulator" — which means that these nerve center gadgets of the flashing buoys are allowed no lee-way in accuracy. These regulators or valves, which the students in this photo are timing so carefully, are adjusted on the split-second, so that the six flashes, each of two-tenths of a second duration, are spaced at six-tenths of a second intervals, with an "eclipse" of six-tenths of a second between. These flash groups, or cycles, are separated from each other by an "eclipse" of four and two-tenths of a second between, thus using eight and four-tenths seconds for the combined cycle of "eclipses" and flashes. (Decimal point sharks are invited to check the arithmetic.) The students in this class at the Coast Guard's aids to navigation school, Detroit, Michigan, who have learned that safety is the first rule of the sea, are now studying, by actual test, the secrets of the acetylene-fed buoys.
