Full titles differ between systems:

IPC:

Generation of oscillations using amplifier with regenerative feedback from output to input

CPC:

Generation of oscillations using amplifier with regenerative feedback from output to input (H03B9/00, H03B15/00 take precedence)

Tank circuit a parallel LC circuit, particularly in a high power transmitter circuit
