  • Capillary processing unit
    Patent number: 4327058
    Abstract: A system for the manufacture of synthetic hydrocarbon products from coal or similar carbonaceous solids is described. This coal liquefaction system includes means for reducing the pressure of high pressure and temperature liquid reaction product streams without attendant corrosion of the metal parts in the pressure reducing unit.

  • Control unit for a serial printer
    Patent number: 4324499
    Abstract: In a serial printer of the type having a carriage continuously moved along a printing line and supporting a type-member intermittently rotated for selecting the next character being printed, a control unit is provided which performs an algorithm for executing a forecast calculation of the residual time missing in every moment to the type-member for positioning the character being printed. The same control unit calculates a correspondent speed of the carriage depending on that residual time and on the position reached by the carriage on the printing line. The speed of the carriage is thereby continuously controlled from the preceding to the new printing position for causing the printing of the selected character exactly on the printing position at the maximum speed of the carriage consistent with a good print operation.

  • Electronic typewriter with display device
    Patent number: 4323315
    Abstract: 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.

  • Machine for typing characters
    Patent number: 4320980
    Abstract: Characters are typed in reverse, i.e. light characters on a dark background by first typing all over the field of the character using an ink ribbon, back spacing and typing the character using a correcting ribbon. The first typing may be effected with a solid character covering the whole field in one or a few operations but, in the preferred embodiment is effected by repeatedly typing a vertical bar with tiny line feed increments, say 1/120". The first typing may take place on depression of a special key, which also effects the back spacing and the correcting ribbon; the character key is then struck. Preferably the whole sequence takes place automatically upon depression of the character key while a mode selector is in REVERSE mode.

  • Method and device for assembling in particular a roller with a journal with interposition of needles
    Patent number: 4317602
    Abstract: The process comprises placing on the journal the roller provided with its needles and the annular member for axially retaining the needles. Thereafter, one end of an elastically yieldable ring is engaged in a passageway provided on the journal and the ring is shifted along this passageway until it is completely received in a groove. This method is much more reliable and lends itself to a thorough automatization.

  • Digital device for synchronizing and decoding coded signals
    Patent number: 4317111
    Abstract: A digital device generates a local frequency and phase signal adapted for the conversion of one of a plurality of codified signals into binary code. The received codified signals are continuously stored in a shift register which is able to contain the signals received in a predetermined period at a time. The output of the shift-register addresses a memory. At predetermined instances of time the memory produces a control word which is input to a counter dependent on the phase of the received signals stored in the shift register. The counter activates output signals at predetermined instances of time in order to produce a local signal in synchronism with the received signal.

  • Support structure for shadow mask of color cathode ray tube
    Patent number: 4315189
    Abstract: In a color cathode ray tube having a glass envelope and panel, a shadow mask is positioned adjacent a phosphor screen in the panel. Supporting members secure the shadow mask to the panel. These supporting members are responsive to the heat generated in the shadow mask to compensate for the thermal expansion of the shadow mask by displacing the shadow mask toward the phosphor screen. The supporting members each comprise a pair of plate-like segments spaced apart along at least a portion of their lengths. The plate-like segments are formed of metals having different coefficients of thermal expansion. No bi-metallic elements are used to form the plate-like segments of the supporting members.

  • Weight portioning method and apparatus
    Patent number: 4313507
    Abstract: Methods of portioning by weight a plurality of articles of randomly varying weight. An array of articles is randomly assembled and then individual weights sensed. Some of these articles are then selected, to add up to the desired total weight. A preliminary step can be used wherein articles of unknown weight are first assembled to form a preliminary weight portion known to be short of the desired final weight, and then articles of known weight are added to reach the final target weight. An apparatus for accomplishing the methods comprises an array of scales dischargable upon signal from a control system, means for resupplying the scales, and a control system for sensing, storing and analyzing the weights of articles in the scales, and causing the proper scales to be discharged.
