Full Title

Full titles differ between systems:

IPC:

Separation of liquids, not provided for elsewhere, e.g. by thermal diffusion > Separation of non-miscible liquids > Breaking emulsions

CPC:

Separation of liquids, not provided for elsewhere, e.g. by thermal diffusion (devices for separating or removing fatty or oily substances or similar floating material from water, waste water, or sewage C02F1/40; cleaning or keeping clear the surface of open water from oil or like materials E02B15/04; arrangements for separating lubricants from refrigerants F25B43/02) > Separation of non-miscible liquids > Breaking emulsions
