Definitions

  • the present invention relates to an improved release or trigger control apparatus particularly adapted, although not limited, for application with ofhce printing machines .and the like.
  • the inventive release or trigger apparatus serves for the timely triggering of an electric operation in dependence upon a revolving scanning or read-out system and storage of the operational information in magnetic storage rings which can assume two different states of magnetization or magnetic conditions.
  • One of the more essential aspects of the present invention resides in the feature that after reading-in or keyingin information corresponding to a desired operation, such information for example representing. a symbol, mark, command or the like, a magnetic storage ring operably associated with such read-in information is brought into one magnetic condition or state and moves out of such one magnetic condition into the other magnetic condition after switching-in an impulse generator, whereby in consequence of the attendant magnetic reversal a trigger or control pulse arrives at a further impulse generator which, in turn, initiates the desired operation, for example a printing operation.
  • the apparatus of the present invention designed for triggering a desired operation generally comprises read-in means for reading-in information relevant to an operation desired to be undertaken, means for storing such read-in information, said storing means incorporating magnetic storage rings capable of assuming two different magnetic states or conditions, one such condition being in response to information stored by said magnetic storage means.
  • read-out means for retrieving the stored information
  • impulse generator means operatively connected with said read-out means for driving the magnetic storage rings into the other magnetic condition
  • conductor means cooperating with said magnetic storage rings such that the magnetic reversal of a given magnetic storage ring from the aforesaid one magnetic condition into the other magnetic condition generates a trigger pulse in said conductor means
  • imulse generator means responsive to the trigger pulse for initiating the desired operation.
  • the readout means or scanning system can be so constructed that it serves as the pulsing means or timing valve for the driving impulse generator.
  • the readout system preferably incorporates a number of contact lamellae or disks corresponding in number to the number of individual items or bits of information, that is, symbols, marks, commands or the like capable of being read-in, each such denoting a desired operation for example, with such contact disks being wiped or operably acted upon by a revolving contact arm driven at constant or substantially constant rotational speed together with a type Wheel of the printing mechanism.
  • the impulse generator "ice operably associated with the read-out means can also be designed to embody means rotatable about an axis, what may be conveniently considered herein as a revolving or rotatable impulse generator.
  • a further important object of the present invention resides in the provision of improved apparatus for triggering a desired operation incorporating magnetic storage means capable of assuming two magnetic conditions, one such condition corresponding to stored information and the other magnetic condition being brought about during retrieval of the stored information, wherein the driving of a given magnetic storage ring from the aforesaid one magnetic condition to the other is utilized to initiate the desired operation.
  • Another important object of this invention is the provision of improved apparatus for triggering a desired operation manifested by its relatively simple construction yet highly reliable performance and accuracy.
  • Still a further important object of the present invention is to provide improved apparatus for triggering a desired operation comprising magnetic storage rings for storing information relevant to the operation desired to be performed, read-out means for retrieving the stored information from a corresponding magnetic storage ring, said read-out means being designed as a timing valve for an impulse generator for magnetically driving said magnetic storage rings.
  • FIGURE 1 schematically illustrates a first embodiment of release or trigger control apparatus designed according to the present invention
  • FIGURE 2 is an arrangement similar to FIGURE 1, yet incorporating a diiferent type of scanning or read-out system;
  • FIGURE 3 shows details of a magnetic storage ring arrangement employed in the embodiment of FIGURE 1;
  • FIGURE 4 illustrates details of a magnetic storage ring arrangement employed in the modified embodiment of FIGURE 2.
  • FIGURE 5 schematically depicts details of a so-called revolving impulse generator adapted to be employed in the embodiment of FiGURE 2.
  • a drive motor 2 having a shaft 1 driven at constant rotational speed and upon which there is arranged a suitable type wheel 3 and contact arm 4.
  • This revolving contact arm 4 forms part of a scanning or readout system which embodies at least as many contact lamellae or disks 20A, 20B, 20C, 20D etc. as the type wheel 3 carries symbols, marks, indicia or the like. It is further to be recognized that each contact disk 20A, 20B, 20C, 20D, etc. is electrically coupled via a respective conductor ltia, 10b, 19c, 10d etc.
  • the operating contact 10 is closed, whereby the impulse generator 11 is electrically coupled via conductor 17 with the revolving contact arm 4.
  • the impulse generator 11 has imparted to it zero potential. Consequently, such impulse generator 11 delivers a steep or abrupt rectangular pulse of negative polarity. Such pulse occurs so quickly that the contact arm 4 is still located upon the contact disk 20A and permits current flow through the conductor 10a piercingly extending through the associated magnetic storage ring 8A. As a result, the magnetic storage ring 8A is driven or switched into the other magnetic state or condition.
  • a voltage or trigger pulse is induced in conductor 16 piercingly extending through all of the magnetic storage rings 8A, 8B, 8C, 8D etc. which, in turn, causes an impulse generator 12 electrically coupled with conductor 16 to deliver a rectangular pulse of positive polarity.
  • an electromagnet 13 At the output side of this impulse generator 12 there is operatively connected an electromagnet 13 which attracts an armature or tongue 15a subjected to the action of spring means 14, thereby pressing a paper tape, band 15 or the like against type wheel 3. Since the type wheel 3 travels in synchronism with the revolving contact arm 4 the infed information e.g. symbol read-in by means of the read-in key A, is printed upon such paper tape or band 15.
  • the aforedescribed embodiment employs so-called flying or continuous printing, that is to say, the type wheel rotates continuously.
  • so-called stationary printing wherein the type wheel is brought to standstill during the actual printing activity.
  • a type wheel drive incorporating a slipping clutch, ratchet wheel and magnetic triggered pawl.
  • FIGURE 2 The variant embodiment of FIGURE 2 is constructed to operate with a different read-out or scanning system.
  • a given information read-in key E, F, G, H etc. of the operating key arrangement 27 the corresponding information e.g. symbol, command or otherwise is stored in the associated magnetic storage ring 28E, 28F, 28G, 28H etc. in the manner aforedescribed.
  • the scanning or read-out system of this embodiment includes a revolving magnet 24 which sweeps past ringshaped induction coils 25, each such coil being operably associated with a respective conductor 25E, 25F, 25G, 25H
  • the revolving magnet 24 of the embodiment of FIGURE 2 it will be appreciated that such is a permanent magnet for example.
  • a revolving electromagnet could also be employed, whereby under these circumstances a tripping pulse of sufficient strength may be generated to render the impulse generator 43 superfluous.
  • the impulse generator 43 for rotating or revolving movement. Such an arrangement is shown for example in FIGURE 5, wherein the so-called revolving impulse generator depicted thereat embodies a suitable revolving magnet 51 which is synchronously driven with the revolving magnet 24 of the read-out system.
  • This revolving magnet 51 of the impulse generator cooperates in known manner with suitable coils 50, advantageously corresponding in number to the number of coils 25 of the aforesaid read-out system. It should thus be apparent that as the magnet 24 of the read-out system rotates the magnet 51 is driven in synchronism therewith and thereby induces generation of suitable pulses in the coils 50 of the impulse generator 43, for reasons previously explained in detail herein.
