    摘要: The system comprises at least one teleprinter station (1) connected to an exchange (3) by means of a transmission-reception line (2) and comprising a polarity detector (31) for the line circulating current, and a device (30) for reversing the connection of the line wires. If the wires erroneously become reversely connected following maintenance work on a line of single current type, then false call and conversation signals are generated which automatically trigger a checking operation in which the polarity detector is suitably examined under control of a ROM routine E controlling a CPU 84. If the current is found to be the reverse of the correct current, the reversing device is operated in order to reverse the polarity of the connection. In contrast, in the case of a double current line, the reversing device is operated when current is absent in the reception line, thus indicating an erroneous line connection. If the line current interruption is prolonged, a warning device (28) is activated.

    摘要: The device comprises an electrically insulating ink container containing one electrode and a counter-electrode disposed adjacent to the jet nozzle which is laser-bored through the container cover plate. The two electrodes are excited by a voltage pulse such as to generate a spark between the ink meniscus and the counter-electrode, and to expel a plurality of ink particles, rather than a single blob. The ink can be kept in circulation between the container and a reservoir 51 by means of a pump. The meniscus can be kept outside the nozzle by means of a second nozzle coaxial to the first, or by a suitable arrangement of the ink hydraulic circuit. In the case of magnetic ink, the meniscus is pulled back by a magnetic field. The ink can also be brought in front of the nozzle by capillarity.

    摘要: A printing device comprising a printing head having 18 wires actuated by a corresponding number of control electro-magnets for writing on a recording support symbols and characters in conformity with dot matrices. The writing ends of the wires are aligned along a single line, the slanting of which relative to the direction of movement of the carriage is variable. With the writing ends vertically aligned the height of the 18 wires is equal to that of two lines of writing, as a result of which it is possible to print two rows of characters simultaneously. By inclining the head and suitably selecting the speed of movement it is possible to print a line at a time with high definition dot matrices.

    摘要: The tracing element is carried by one vertex of an articulated parallelogram, of which the arms are constituted by thin steel or glass fibres associated with a plastics coating or matrix for damping vibrations. The arms are moved by servocontrols constituted by electromagnets with moving coils having a length less than the length of the corresponding magnet pole piece. The coils are formed from a conductor of square or rectangular cross-section in order to provide maximum packing for the turns.

    摘要: The printer comprises electrodes arrayed in circumferential rings and rows parallel to the axis of a cylinder. This axis corresponds to the vertical direction of characters printed on a sheet of paper. The print cylinder is moved in the direction of a line of print transversely to the direction of feed movement of the paper and rotates with respect to the paper in order to avoid sliding movement. A movable inked ribbon is disposed against the top face of the paper on which the printing is to be effected, and on the opposite side to the print cylinder. The inked ribbon is electrically conducting and connected to one terminal of the power supply which selectively energizes the electrodes. The ribbon is moved in the same direction as the print cylinder by means of drive rollers. The inked ribbon passes through an inking station for continuously renewing the layer of ink. The inked ribbon is also moved in the same direction as the paper by a face cam to ensure there is always a freshly inked band of the ribbon opposite the electrodes but this may not be necessary and is a feature omitted from a modified embodiment in which the ribbon rollers drive it in the direction of paper feed.

    摘要: An electronic typewriter having a display device which shows just the last entered characters of a printing line. The typewriter comprises a selector for an immediate typing mode of the entered character, a line/line mode in which each line is set up in memory and typed on operating a service key, and a word/word mode in which the set up words are typed word by word, i.e. on each operation of the space bar. This facilitates typing with checking to eliminate all errors. The display device shows emphasized characters, different kinds of emphasis (heavy type, light type on dark background being indicated by different luminous dot patterns under the characters. The display device is of the dot matrix type and, by suitable circuits thereto superposed characters, e.g. 0 and 1 yielding .phi., are correctly shown.

    摘要: In a copying machine having a movable carriage 5 for carrying the original, the correct velocity ratio between the carriage and the drive shaft 18 which advances the photosensitive sheet 21 (or photosensitive drum) is established by driving the carriage from a shaft 25 at overspeed through a friction clutch 38 and limiting the carriage velocity to the correct value by a coupling (rack 32, gears 40,43, one-way clutch 29) between the carriage 5 and the drive shaft 18. The correct velocity is thereby maintained irrespective of wear and tolerances in the drive to the carriage and the carriage guides.

    摘要: An apparatus for recording binary information on a flexible magnetic disk of small dimension, comprises a rotatable hub connected to a plate on a first surface of which is formed a spiral guide. The hub has a cylindrical portion engageable accurately with a corresponding central hole of the disk and it is provided with a radial driving dog engageable on the fly, and with play, with a corresponding radial notch opening out of the central hole. A recording head is mounted at the end of an arm which has an element cooperating with the spiral guide of the plate for being moved, radially with respect to the disk, in synchronism with the rotation of the plate and of the same disk.
