(under subclass 137) Subject matter having adjustable means to selectively form a closed circuit with one or more turns of the coil.
(1) Note. An illustrative example is: [figure]
SEE OR SEARCH THIS CLASS, SUBCLASS:
15, for inductor devices in which the number of effective turns of a coil is changed by winding or unwinding the coil conductors upon a short circuiting member.
73+, for inductor devices with closed coil, particularly indented subclasses 75+ where the closed coil (e.g., the short circuited turns) is movable relative to the coil.
138, for similar adjustable inductor devices having a plurality of parallel spaced coil members, a bridging member being movable along the coils to short circuit equivalent portions of both coils.
