Full Title

Full titles differ between systems:

IPC:

Arrangements for handling mechanical energy structurally associated with dynamo-electric machines, e.g. structural association with mechanical driving motors or auxiliary dynamo-electric machines > Means for converting reciprocating motion into rotary motion or > Electromechanical oscillators; Vibrating magnetic drives

CPC:

Arrangements for handling mechanical energy structurally associated with dynamo-electric machines, e.g. structural association with mechanical driving motors or auxiliary dynamo-electric machines > Means for converting reciprocating motion into rotary motion or vice versa > Electromechanical oscillators; Vibrating magnetic drives

No child classifications to compare. This is a leaf node in both IPC and CPC.
