.~.~ Relatively movable core and coil-type transformer
DEFINITION
Classification: 315/281
(under subclass 276) Systems in which the transformer is provided with means for varying the inductive coupling between the windings, the inductive coupling being varied by (1) arranging one of the transformer windings so as to have free relative movement with respect to the other winding and/or the transformer core, or (2) arranging the transformer core so as to have free relative movement with respect to the transformer windings, or (3) using a transformer having a
core made of two or more parts, at least one of the parts being arranged so as to have free relative movement with respect to another of the core parts.
