Full Title
Full titles differ between systems:
IPC:
Processes or apparatus for generating mechanical vibrations of infrasonic, sonic or ultrasonic frequency > making use of mechanical energy > operating with systems involving reciprocating masses
CPC:
Methods or apparatus for generating mechanical vibrations of infrasonic, sonic, or ultrasonic frequency > making use of mechanical energy (B06B1/18, B06B1/20 take precedence) > operating with systems involving reciprocating masses
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
