Without limiting myself therefore any
specific form, what claim is—
1. The combination, with independent elec
tric transmission-circuits, transformers con
sisting annular similar cores wound with
primary and secondary coils, the opposite pri
mary coils each transformer being connected 40
to one the transmission-circuits, alter
nating-current generator with independent in
duced armature coils connected with the
transmission-circuits,whereby alternating cur
rents may directed through the primary 45
coils the transformers the order and man
ner herein described. refer more particularly
to the form the core, the relative lengths
io and resistances the primary and secondary
coils, and the arrangements for running op-
' erating the same. 35

The modifications which are applicable to
other forms converter are many respects
