B06B 1/14 the masses being elastically coupled
Introduced: September 1968
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 > the masses being elastically coupled
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 > the masses being elastically coupled
No child classifications to compare. This is a leaf node in both IPC and CPC.
