Perhaps you should try some spelling variations:
dc transformer » _ transformer, 3 transformer, se transformer
a transformer » _ transformer, a transformed, 3 transformer
net transfer » net transfers, heat transfer, money transfer
transfer bei » transfer beim, transfers bei, transfer der
bias ende » bis ende, bias index, das ende
4 across » 19 across, eu across, ct across
bei marc » bei marx, bei maria, bei carl
luis c » luis f
c net » ic net, _ net, a net

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: (( bias ende ((dc transformer) OR (a transformer)) 4 across ) OR ( luis c net transfer bei marc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bias ende ((dc transformer) OR (a transformer)) 4 across ) or ( luis c net transfer bei marc ))~".
• Adding a wildcard symbol may retrieve word variants: (( bias ende ((dc transformer) OR (a transformer)) 4 across ) or ( luis c net transfer bei marc ))*.
