If you mean the difference between Tungar and Rectigon, I don't think
there is any difference. These are gas filled half wave rectifers intended 
for use
in battery chargers. The gas is usually argon. Tungar is the GE name
and Rectigon (I think, but  never saw one) is the Westinghouse trade name.
They were widely used during the 1930's and into the 40s.

The transformer used with these things is a step-down to bring the DC voltage 
to
something near the battery voltage. The filaments are tungsten.
