Titles differ between systems:

IPC: Handling the filter cake in the filter for purposes other than for regenerating

CPC: Handling the filter cake in the filter for purposes other than for regenerating (B01D29/94 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Filters with filtering elements stationary during filtration, e.g. pressure or suction filters, not covered by groups; Filtering elements therefor > Handling the filter cake in the filter for purposes other than for regenerating

CPC:

Filters with filtering elements stationary during filtration, e.g. pressure or suction filters, not covered by groups B01D24/00 - B01D27/00; Filtering elements therefor > Handling the filter cake in the filter for purposes other than for regenerating (B01D29/94 takes precedence)

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1990.
