Abstract: A variable inductor is provided. The variable inductor includes a dielectric core having a helical thread on an outer surface thereof for receiving the coil, and a non-magnetic element positioned coaxially within the core. The non-magnetic element could be provided in the form of a bushing or a solid rod, and could be manufactured from any suitable, non-magnetic metal, such as copper, brass, etc.

Abstract: A coaxial attenuator is provided. The attenuator includes a central body with first and second sockets at opposite ends thereof, outer conductors threadably engageable with the first and second sockets, inner conductors coaxial with the outer conductors, a resistive element or “chip” positioned within the central body, and a floating shroud or jack adapter captured between the central body and one of the outer conductors. Transverse slots are formed in ends of the inner conductors to create flexible ends which contact and bias sides of the resistive element. The floating shroud includes an internal, annular projection which is captured between a shoulder formed in the outer conductor and a side of the central body, allowing the shroud to be captured on the attenuator while permitting movement of the shroud with respect to the central body and the outer conductor.

Abstract: A trimmer capacitor is provided which includes a conductive bushing having a first terminal of the capacitor formed integrally therewith, a rotor threadably engageable with the bushing, and a dielectric portion attached at one end to the bushing and having a metallized stator surrounding the dielectric portion near the opposite end thereof. The metallized stator forms the second terminal of the capacitor, and is positioned above the bottom edge of the dielectric portion. The rotor includes transverse slots which bias the rotor in position against the bushing, to prevent undesired rotation of the rotor.

Abstract: The disclosure describes a connector for fiber optic transmission cables, incorporating into it a variable attenuator. The variable attenuation is achieved by having a screw arrangement vary an air gap, and additional embodiments of the invention feature ways of fixing the attenuation at a given level and of minimizing back-reflection.
