    摘要： The present invention relates to a method for preparing a highly pure trifluoromethanesulphinic acid. The method of the invention for preparing a highly pure trifluoromethanesulphinic acid, starting from an aqueous mixture comprising a trifluoromethanesulphinic acid salt, a trifluoroacetic acid salt and saline impurities resulting from the method for preparing same, is characterized in that said mixture is subjected to the following operations: —acidification such that the trifluoroacetic acid salt and the triflinic acid salt are released in an acid form, —separation of the trifluoroacetic acid and trifluoromethanesulphinic acid by distillation enabling the trifluoroacetic acid to be recovered at the top of the distillation and the trifluoromethanesulphinic acid to be recovered at the bottom of the distillation, —separation by distillation of the trifluoromethanesulphinic acid present in the distillation residue previously obtained.

    摘要： A server system is connected to a number of remote displays for messages for broadcasting by a communication network. The audiovisual messages received from the server system are made perceptible for customers. The customers can send coded instruction signals to a first access device, located near a display, by portable customer badges, which are transmitted to the server system which then establishes a back-up communication with the customer, for example, through a portable telephone. The customer can thus simply establish communication and, when the server system has information specifically concerning the above, the information need not be transmitted over the network.
