Perhaps you should try some spelling variations:
den transformer » dc transformer, se transformer, _ transformer
transformer ct » transformer 1, transformer _, transformer 4
transfer beim » transfer bei, transfers bei, transfer axiom
bias ende » bis ende, bias index, das ende
ct across » cil across, 19 across, eu across
beim marc » bei marc
ende den » ende der, ende des, wende der
luis 1 » luis f, luis c, luis a
1 heat » 1 wheat, 10 heat, c1 heat

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 den transformer ct across ) OR ( luis 1 heat transfer beim marc ))~.
• Adding a wildcard symbol may retrieve word variants: (( bias ende den transformer ct across ) or ( luis 1 heat transfer beim marc ))*.
