DEFINITION

Classification: 315/39.59

(under subclass 39.55) Devices which have a movable element for varying the tuning or impedance of the distributed impedance structure, the movable element being actuated by a thermal or magnetic motor means.

(1) Note. The thermal motor means may be a thermostat. The magnetic motor means may be an electromagnet.

(2) Note. The thermal or magnetic motor means may vary the position of one portion of the distributed impedance structure with respect to some other portion or a tuning element may be moved into proximity to or away from some portion of the impedance structure.
