Definitions

  • This invention relates to impulse counting systems and more particularly to a counting chain made up of a plurality of electromagnetic impulse counting devices of the type having multiple armatures associated with a common energizing system and separate contact means associated with each armature.
  • the invention is particularly directed to an arrangement whereby a plurality of electromagnetic devices of the type above-mentioned operate in succession to count more than the number of impulses which is the limit of each.
  • the type of counting device utilized may be of the type for instance disclosed in the copending application of U. Hubner, filed June 23, 1954, bearing Serial No. 43 8,713 and entitled Electromagnetic Impulse Counter, or similar to reissue Patent No. 23,089 to Bellamy.
  • Relay counting chains are known and serve as test distributors, test selectors, or key senders, etc. in com munications applications and are either controlled by impulses or when started, continue their progress automatically. In the normal system, a separate distributor is required to switch successive counters into circuit. This invention eliminates the necessity for any distributing means. Accordingly, it is an object of this invention to provide an impulse counting circuit utilizing a plurality of counting devices of the type above mentioned so interconnecting said devices that they are formed into a chain and operate in succession.
  • This invention permits the realization of a relay chain which is simple and which may serve as a test distributor or test selector having a large number of outlets.
  • the electromagnetic impulse counting device utilized in this invention is of the type having a plurality of armatures associated with a common energizing winding and the operation of the first armature of the device prepares the next succeeding armature for operation upon the receipt of the impulse.
  • These devices are decadic and have a separate recycling or release windings which releases all of the armatures at the conclusion of the tenth impulse and movement of the tenth armature in response thereto.
  • the arrows shown above the relay windings indicate the direction of the flux in the energizing winding necessary to attract armatures 1 to 0 sequentially.
  • the windings marked A F represent the recycling or release windings associated with each of the impulse counters A F and the arrow over the winding indicates the direction of the magnetic flux necessary to cause release of the associated counting device.
  • an impulse sender IS which essentially consists of transfer contact i which has its movable contact connected to ground through break contact p1 which is associated with test relay P and the front contact of transfer contact set m2 associated with starting relay AN.
  • the series of lines 1 54 are each coupled to a make contact a1 f9 and which contacts are associated with the several armatures of the counting devices A 'F.
  • the break contacts a1 f9 are also associated with the several devices A F.
  • the relay H is a slow release relay and its purpose will be explained later in connection with the description of the operation of the circuit.
  • each counting device (a0 f0) serves to transfer impulses from one device to the next in the chain upon the receipt of the tenth impulse to that device.
  • Starting relay AN is closed by a suitable means and which for the purposes of this description is shown as switch SW.
  • Contact art-1 completes a circuit to operate impulse sender IS and which impulse sender may be of a known form.
  • Transfer contact an2 is now in its make position and completes a path from ground to the movable contact i of the impulse sender via normally closed contact pl.
  • a path for the energization and the operation of device A is completed via: an2front p1, i front, b0 back, winding A, Counting device A will respond to the next 9 impulses, pulling up a dif 'ferent one of its armatures upon the receipt of each impulse from impulse sender IS.
  • contact at) closes and prepares a path for the energization of the energizing winding of counting device B via: winding of device B, back contact 00, all make, back contact of impulse sender IS.
  • an energizing circuit for winding B upon the next excursion of the movable contact i to its operating back contact, an energizing circuit for winding B, will be completed via: (1112 front, p1 make, i back, a0 make, 00 back, energizing winding of device B, Upon each excursion of the movable contact i to its front contact, an impulse will be applied to the energizing winding of counter A, but since counter A has responded to the tenth impulse and all its armatures are attracted to its core, these further impulses will have no effect and will continually be applied until contact changes its position, as will now be explained.
  • the contact b0 Upon the receipt of the 19th impulse the contact b0 moves to its make position and completes a circuit for the energization of device C which operates in a similar manner to that described with respect to device B.
  • the devices D, E and F operate sequentially upon receipt of the 27th to 35th impulse, 36th to 44th impulse, 45th to 54th impulse, respectively.
  • transfer contact it Upon receipt of the 54th impulse, transfer contact it) moves to its make position and completes a circuit for the energizing of the recycling or resetting winding A via: negative, winding A, f0 front, d0 front, b0 front, through impulse sender contact 1' to positive via contacts p1 and 11112 to positive.
  • relay P and contact 121 will be shorted and which short is indicated in the drawing by dot-dash lines.
  • the chain is disconnected by deenergization of the starting relay AN through whose contact art-2 the application of positive potential to the impulse sender controls the sequential operation of the several counting devices. Release of relay AN results in the energization of slowrelease relay H via back contact anIV.
  • the slow release relay H will maintain its contact 111 closed during the release time of relay AN and a path for the energization of the restoring windings of the counters would be completed via: plus, back transfer contact an/II, front contact I11, restorting winding A and a parallel circuit via back contact anV and a series connection among the restoring windings B F, minus.
  • a circuit will be completed for the recycling coil A, as first above traced. As explained before the release of device A will thereupon cause the energization by means of the contact 001 and the consequent release of counter B F.
  • An electrical impulse counting circuit comprising a plurality of electromagnetic impulse counters, each being of the type having a common energizing winding, a common restoring winding, a series of multiple armatures associated with said windings and separate electrical contacts associated with each-of said armatures, said armatures successively operated in response to successive pulses, respectively, said counters arranged in a chain of odd and even groups, a source of operating impulses, an energizing circuit :for the energizing winding of the first counter in the odd group extending to said source over a back contact of the first counter in said even group, an energizing circuit for the energizing winding of the first counter in said even group extending to said source over a front contact of the first counter in said odd group and a back contact of the second counter in said odd group, each succeeding counter in each group having an energizing circuit which includes the closed ultimate contacts of all previously operated counters in the opposite group of the chain, and a restoring circuit for connecting the
  • An impulse counting circuit as claimed in claim 2, wherein said additional restoring circuit comprises a series connection among said restoring contact and the restoring windings of the balance of the counters of said chain.
