Abstract: An electronic device comprises a microprocessor having a data input; a data output and a control input as well as at least one memory unit, especially a memory unit formed by means of a persistent memory component. The microprocessor includes at least two operating modes selectively activatable via the control input and is adapted to execute in a first operating mode at least one predetermined control program, in order to process digital data incoming via the data input and/or in order to output digital data on the data output, and in a second operating mode to be reprogrammable, in such a manner that at least one value of a parameter, which influences execution of the at least one process flow program by the microprocessor, is changeable.

Abstract: A vessel for the storage of cooled liquids, particularly beverages, is surrounded by a thermally insulating jacket. First and second cooling coils or analogous devices are interposed between the vessel and the jacket and surround the vessel from opposite sides of the same over 50-75% of its surface area. Water refrigerated to about 0.degree. C. is circulated through these cooling coils.
