Patent ES-391039-A1 (ES)
Title: Receiver timing and synchronization system
IPC: H03L7/099
Filed: 1971-05-11
Abstract: A receiver timing and synchronization system useful in a digital data communication system for providing timing signals synchronized with received digital data. The receiver system includes means for providing small incremental changes in the locally generated timing signals to maintain synchronization as well as means for enabling synchronization to be maintained during signal fades. In addition, means are provided for rapidly re-synchronizing the timing signals to data received from a new transmitter. Incremental timing signal adjustments are made by determining whether a data signal transition occurs during an early, on time, or late portion of a bit period. If a data transition occurs during early or late portions, the timing signal is either incrementally advanced or retarded. If data transitions occur during corresponding portions of n successive bit periods outside of the on time portion, then the timing signal is jammed into synchronization with the recurring data transitions.

Title: Method and device for enclosing a cable splice
IPC: H02G1/14
Filed: 1977-01-21
Abstract: The covering comprises a compressibly foamed plastic (24, 26), wound around the cables (12, 14) at a distance from the splice (10), and flexible film material (22) as a covering of the splice, which material is held securely on the compressibly foamed plastic (24, 26). The consequently enclosed cavity is filled by rigid-foamed plastic (46). This covering can be produced at low costs for labour and material, because the splice does not have to be fixed during curing this is since the compressibly foamed plastic (24, 26) and the film material (22) form a housing in which the curing plastic (46) is pressed into all the cavities. Therefore, lashing errors are greatly reduced and any installation errors can be seen immediately and can be rectified.
