transformer spanned » transformer based
dc transformer » _ transformer, 3 transformer, a transformer
spanned across » shared across, space across
net transfer » net transfers, heat transfer, money transfer
transfer bei » transfer beim, transfers bei, transfer der
ende dc » ende der, ende des, ende den
luis a » luis f, luis c
a net » a new, _ net, a neo
bis » bias

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( bis ende dc transformer spanned across ) OR ( luis a net transfer bei (mark OR mary) ))~.
• Adding a wildcard symbol may retrieve word variants: (( bis ende dc transformer spanned across ) or ( luis a net transfer bei (mark or mary) ))*.
