Resistor rig from the patent can be compared with radio ham where we adjust frequency by moving a contact along the solenoid and using only part of the coil … this is what rotary commutator doing with resistor rig.

Easy to understand why resistance is used as parametric excitation in this way, where we can manipulate inductance, impedance and capacitance of the whole circuit and how frequency of changing influence all of them.
