Differences between “Polytechnic” and “Technology”? Some universities are called Polytechnic and some other contain Technology in their name, for example the Valencia Polytechnic University (UPV) vs. the Technical University of Berlin (TUB).

What are the differences between them?
Wikipedia has a nice summary of this distinction (or lack thereof).  In essence: the term "polytechnic" comes from the French École Polytechnique.  Thus, a university with 'Polytechnic' in its name is typically one that was influenced in its founding in some way by the French system.  Today, however, there is generally no significant difference.
