1. The combination with conductor se- 90
ries conductors constituting one terminal
of circuit-controller, means formaintaining
a stream jet conducting fluid the
other terminal with which the conductor
makes intermittent contact, close recepta- 95
cle containing the terminals, and means for

is conducting fluid, such mercury, a
receptacle inclosing the same and means for
maintaining inert gas under pressure in
the receptacle. The combination with receptacle, of
a conductor series spaced conductors

ing said conductors, one moré nozzles for no

conductor, and force-pump direct con
nection.

convenience, the receptacle metal cup

to will now more readily appear.
