DEFINITION
Classification: 331/95
(under the class definition) Subject matter wherein the
frequency determining element of the oscillator comprises a variable split stator capacitor, the stator plates being in general circular discs having a symmetrical opening therein of butterfly wing configuration, the rotor plates having a corresponding butterfly shape and being in interleaving or meshing relation to the stator plates and being rotatable about an axis normal to and passing through the center of symmetry of the surface of the rotor plates. The arrangement is such that both the capacitance and inductance of the device vary at a function of the rotor position.
