Abstract: The method involves a transmission arrangement (10), in which at least one auxiliary signal is generated with a frequency which is higher than that of the digital signal and is fed under the control of the status information to a transmission unit (22), whence it is transmitted via a transmission path to a receiving arrangement (11). The auxiliary signal is used there to reconstitute the digital signal and status information. A digital transmission signal is generated in the transmission arrangement (10) by combining the digital signal and the auxiliary signal in an OR-operation and is fed to the transmission unit (22) only if one of the two possible status information conditions prevails. The digital signal and status information are regenerated in the receiving arrangement (11) due to the occurrence of changes in state and due to the current state of the digital transmission signal. <IMAGE>

Abstract: To recover binary information from a faulty composite baseband signal, particularly a D2-MAC signal, a control signal for a control amplifier (V) is derived from a peak-value detection (SD1, SD2). Signal components located outside this data burst are gated out during the control process. The output signal of the control amplifier (V) is supplied to a duo binary/binary decoder (DB) the decider thresholds of which are controlled in dependence of the positive and negative peak values of the data burst. Due to the measures of the invention, the duo binary/binary decoder (DB) always operates optimally independently of the signal amplitude of the signal to be decoded. <IMAGE>

Abstract: A franking machine is disclosed in which printing of a franking impression is effected by exposing a layer of micro-capsules containing ink to light to thereby cause hardening of the exposed micro-capsules and then subjecting the layer to pressure to rupture the un-exposed micro-capsules in the presence of a developer with which the ink reacts to become visible. The layer of micro-­capsules may be coated on envelopes (21) or label tape (30) during manufacture or by coating means (36) in the franking machine (10, 11). The developer may be applied as a coating in a similar manner. Alternatively one or both the micro-capsules and the developer may be carried on a transfer film (31) brought into contact under pressure (34, 35) with a mail item (30) after exposure (33) of the film.
