  Weakly nonlocal thermodynamic theories are critically revisited. A
relocalized, irreversible thermodynamic theory of nonlocal phenomena is given,
based on a modified form of the entropy current and new kind of internal
variables, the so called current multipliers. The treatment is restricted to
deal with nonlocality connected to dynamic thermodynamic variables. Several
classical equations are derived, including Guyer-Krumhansl, Ginzburg-Landau and
Cahn-Hilliard type equations.
