ABSTRACT:
Adjustable capacitors for incorporation with any substrate design, and for other general or specific capacitor uses, comprising a dielectric housing means, having base and sidewall eminating therefrom, a rotatable rotor (within said housing means), constructed from a highly conductive metal, having a cylindrical hub and at least one contoured blade plate emanating from the base of said hub, and a metallic retainer, coaxial with and encompassing said rotor hub, to captivate itself against said sidewall in a convex-concave relation to cover and to seal said capacitor assembly and to abut the inner portions of said blade plates to uniformly distribute plate pressure upon the active surface of said dielectric housing base. Displaced from the rotor blade plate by the dielectric housing base are contoured conductive metallized receptive stator electrode layers deposited upon or within said base for connection with receptive substrate circuitry. Thus, simplicity of design results in only three basic parts, the dielectric housing means, the rotor and the retainer.
