Good  way to get double use out of a circuit!

What  Duncan is talking about is a WW-II expedient to increase  traffic
capacity.  A two-headed XD was made with the usual start and  stop
distributor segments and the other five divided in two.  One  read
head was connected the the early segments and the other to the  late
segments.  For receiving you would adjust the range finder on a  printer
so that it would sample in the early half of the pulse time or in  the
late half.  Thus you have two-channel multiplex, assuming the  circuit
was good enough to deliver sufficiently distortion-free  signals
to the printers.
