	OK  --  so I Don't know.    After doing a Giggle search it
appears as though it could be someone's name applied to the
signal, probably the developer's name.    Many organic chemists
with this name doing doing Nuclear Magnetic Resonance (NMR)
testing of materials.

		for Pacific Electric:::::::

	The signals used were the Nachod type.    Signals' normal
indication was dark; they were located ahead of switch points so
trainmen could see them operate.    Trains were held to four mph
while passing signal contactors.    After trolley contacted
contactor, car could proceed if signal showed white light and
white disc; approaching signal showing white indicated a train in
block ahead going in same direction; train could proceed if
signal blinked when the trolley passed contactor.    If signal
displayed red light and red disc, train had to stop until signal
cleared.    If opposing trains passed contactors at the same
instant, signals remained dark; both then had to back into the
siding, not allowing trolley pole to touch contactor; inbound
then proceeded if able to get correct signal indication; outbound
train had to wait three minutes if signal remained dark, then
proceed if able to get correct indication.    Trains could not
reverse direction between contactors.    If power failed, signals
remained dark and all trains had to stop.
