Process for the synthesis of FLECAINIDE comprising the reaction between 2,5-dihydroxybenzoic acid with trifluoroethanol perfluorobutanesulphonate to give the intermediate trifluoroethanol 2,5-bis-trifluoroethoxybenzoate, the reaction of said intermediate with 2-aminomethylpiperidine to give FLECAINIDE. The hypothesis tester checks a received sequence against a group of predetermined sequences that possibly could have been sent to the UE. Preferably, the lotion emulsion is a waterless micro-emulsion which is also capable of forming an aqueous micro-emulsion with water. The pinions, disposed between the guiding components, are meshed with the racks, and the guiding components are engaged with the guiding portions so as to be slidable.
