Abstract: RIBBON ADVANCING MECHANISM                ABSTRACT OF THE DISCLOSURE            In order to advance an inked ribbon in a printing apparatus in which a printing carriage moves across the width of a platen, one-way brakes are placed on ribbon guide rollers on the carriage to permit relative movement between the carriage and the ribbon as the carriage is advancing from left-to-right across the paper.  One-way brakes are placed on return rollers in the ribbon path in order to prevent the ribbon from moving with respect to the platen as the carriage is moving from left-to-right across the paper.  when the carriage moves from right-to-left in order to return to the left-hand margin, the one-way brakes on the ribbon guide rollers on the carriage apply sub-stantial friction to the inked ribbon and drag the ribbon with the carriage as the carriage returns from right-to-left.  In this same motion the return rollers rotate freely to allow the ribbon to move in accordance with the carriage motion.

Abstract: PHN.8795 ABSTRACT     When a colour television signal is recorded on a video disc and said signal is read a complication arises owing to the asymmetry which is produced in the signal by the various process steps. This gives rise to spurious components whose influence should be minimized by a suitably selected coding system. The invention proposes a device with which the influence of this asymmetry is automatically reduced. This device comprises two separator stages for supplying two sub-signals which respectively represent the rising and falling edges of the information signal. The phase relationship between these two sub-signals is controlled with the aid of a phase shifter. The control signal required for this is produced with theaid of a detector which responds to an asymmetry component in the information signal. The two corrected sub signals are subsequently recombined to the information signal.

Abstract: ABSTRACT OF THE DISCLOSURE  A file security system for data files associated with a host data processing system.  The host system includes a data security device which contains a secure host master key and is capable of performing a variety of cryptographic operations.          At initialization time, the host system generates a series of file keys for the associated storage media and protects them by enciphering the file keys under a variant of the host master key.  When a data file is to be created, a random number is generated and defined as an operational key enciphered under the file key of a designated storage media.  The host data security device, using the enciphered file key of the designated storage media, transforms the enciphered operational key under control of the host master key into a form which permits the operational key to be used for enciphering host data.  The operational key enciphered under the file key of the designated storage media, as header information, together with the host data enciphered under the operational key is written on the storage media as an enciphered data file.  When the data file is recovered, the host data security device, using the enciphered file key of the designated storage media, transforms the enciphered operational key header information under control of the host master key into a form which permits the operational key to be used for deciphering the enciphered data file to obtain the file data in clear form.
