Abstract
Installation for the remote transmission of facsimiles, comprising a telecopy transmitter device connected by a telephone line to a telecopy receiver device and comprising two buffer memories adapting the transmission speed of the line to that of the transmitter and to that of the receiver respectively. The buffer memories are each constituted by a multi-track magnetic tape driven by a motor controlled by a time base having high stability; the buffer memory on the receiver side comprises, moreover, an electronic assembly, between the magnetic tape and the telecopy receiver device, intended for compensating short-term changes in speed of the tapes.
