DEFINITION

Classification: 336/155

(under the class definition) Inductor devices comprising an inductor with no relatively movable parts wherein (1) the inductance thereof is variable in response to current flow therethrough or (2) a magnetic shunt or air gap is provided to cause a high leakage reactance between at least two magnetically coupled windings, or (3) the core saturation of the device is controlled by an auxiliary bias means such as a D.C. control winding.

(1) Note. A disclosure in the specification of any of the above enumerated subject matter is sufficient to cause classification in this or indented subclasses of any patent that would otherwise be classified in the succeeding subclasses of this class.
