Abstract: Disclosed is a method of using a flow of abrasive-filled air to adjust an inductive device having a solid core by removing a portion of the core. The dimensions of the resulting air gap thus determine the final value of the device. The inductive device is adjusted after being connected in a circuit to provide the desired frequency response characteristic of the circuit by comparing the actual voltage amplitudes of selected frequency pairs with the desired voltage amplitudes of the same frequency pairs.

Abstract: Disclosed is a subminiature tunable circuit in modular form and the method of making the modular circuit. A capacitor is mounted on an inductor to form a modular tunable circuit. By appropriate connections, either series or parallel reactive circuits are formed with intermediate tap connections, when desired. The circuit is tuned by changing the value of the capacitor by air abrasion techniques.
