Definitions

  • This invention relates in general to automatic telephone systems and in particular to circuits within such systems for registering information.
  • called number digit can be represented by 'any'combination of two selected or abnormal conditions out of five unselected or normal conditions.
  • inregister circuits commonly employed to register the digits of a called or calling number, as well as other items of information useful in the operation of automatic telephone systems five register relays may be employed in a normally non-operated status such thatin order to register any desired digit of a called number a prescribed combination of two operated relays out of the five will be intelligible into a digit by associated apparatus.
  • the present invention is directed to improvement of such register circuits.
  • the invention is not limited in its scope to called number digit registration since, as will be apparent to those skilled in the pertinent art, the invention is applicable to any registration system wherein such coded information is to be recorded for future use.
  • the invention is not necessarily limited in its application to "two-out-of-flve code" signaling.
  • the invention is applied to a telephone system as disclosed in Patent 2,332,912 to G. Hecht, 'A. A. Lundstrom and E. R. Taylor of October 26, 1943, and other patents referred to therein.
  • the Hecht et al. patent discloses a signaling system employing a multifrequency receiver which receives information on a two-out-of-flve frequency basis. That is, a digit comprising information is transmitted to said receiver by means of a prescribed combination of two different frequencies in the audible range.
  • the receiver amplifies this composite signal, separates the two frequencies into two separate channels, checks the existence of two frequencies, permits such frequencies to D- erate two separate digital relays and enables the initiating of digit register functioning to record the information on said two relays as two-out-offive operated register relays.
  • the receiver if it checks improper reception of two frequencies, will effect a recorder on transmissions of the signal previously transmitted to said receiver.
  • the present invention is, of course, not limited in its useful application to such systems as referred to specifically above.
  • Fig. 1 shows an excerpt from the Hecht et al. patent drawing and illustrates, in conjunction with certain descriptive matter hereinafter set forth, the essential parts of a registration system representative of the prior art
  • Fig. 2 shows a circuit embodying elements of the present invention arranged in one of its possible forms to more or less parallel the illustration of Fig. 1.
  • the present invention enables .the use of single winding register relays by so locating a unidirectional current circuit element in the register circuit as to permit the signal Hecht et al. disclosure this source is the afore-' -mentioned receiver circuit wherein, as a result of having resolved a multlfrequency signal transmitted toit,,the receiver operates tworelays which in turn apply ground to two of the five code leads I to 5.
  • a steering 'relay 'I'Rl is operated by closure of an operating circuit therefor over lead 20.
  • relay TRI is operated, other steering relays such as TR2, TR3, 'I'R'l, etc. to TRN (not shown) are operated successively in sequence as fully described in said Hecht et al. patent.
  • Each steering relay such as TRI, corresponds to a digit register, such as III, and arranged in circuit such that when all preceding "steering relays are released the nextonewill connect the five code leads I to 5 to the operate windings of the five register relays of the associated register.
  • code leads I to 5 are connected respectively to armatures I to 5 of relay TRI and, when relay TRI is released, are extended by means of back contacts of said relay TRI to leads II, 22, 33; and 55 "To armatures of next steering relay.
  • polar relay TO indicates completion of registration of information in first digit ing relays.
  • relay T0 eifects the opening of lead 2
  • Relay TRI in releasing opens, at its left outer front contact and operated armature 25, the operating circuit for relay TO and at the same time substitutes, by means of a make-beforebreak contact arrangement, a normally made ground 26 for the ground on the opposite side of relay T0 in order to provide the holding windings of relays I2 and It with a holding circuit.
  • the release of relay TRI transfers code leads I to 5 to the armatures of the next steering relay, such as TR2 (not shown).
  • the release of relay TO prepares the other parts of the circuit (not shown) for registration in a second digit register (not shown) of two-out-offive information representing the second digit to be registered.
  • Fig. 2 a registration circuit which may be substituted for that of Fig. 1 in such a circuit as disclosed by the above Hecht et al. patent and which functions similarly to the circuit of Fig. 1 except as indicated hereinafter.
  • Fig. 2 discloses the present invention in one of its preferred forms. It is to be noticed that the register relays I2 to I6 of Fig. 2 are single wind- It will be appreciated from subsequent description that the use of a unidirectional circuit element, such as copper-oxide rectifier 28, is to a great extent responsible, due to its peculiar location among cooperating parts of the circuit, for the ability of the circuit of Fig. 2 to perform all of the functions of Fig. l and more, while being faster, more comprehensive and more economical.
  • a unidirectional circuit element such as copper-oxide rectifier 28
  • - register relays i2 to It requires the presence of an asymmetrical resistance 28 so disposed in the holding or locking common lead 24 that the signal grounds momentarily transmitted over code leads i to to windings of register relays, such as i2 and it, cannot inadvertently operate check relay N in possible paths over upper operated armatures and front contacts of such register relays.
  • the copper-oxide rectifier element 28, which, of course, could be any suitable asymmetrical resistance element, is so poled that it presents a high resistance to flow of current throughthe winding of relay N over a path completed to ground on side 30 of rectifier 2B but is so poled as to present low resistance to the holding circuits of register relays I: to it when completed to ground on side 3
  • element 28 disclosed as an asymmetrical resistance such as a copper-oxide rectifier
  • any means for such element which is responsive to polarity of voltage so'as to conduct in one direction but not in the other.
  • electronic discharge devices which could fall within that qualification andwhich would operate very satisfactorily for the purpose set forth above.
  • a unidirectional voltage responsive gas tube of the rectifying type or otherwise could be employed. It is well known that such tubes will conduit under the correct polarity and magnitude of voltage but will not conduct upon a reversal of polarity or will be extinguished by a reversal or a withdrawal of such voltage.
  • the full import of the present invention contemplates any such unidirectional device, whether an asymmetrical resistance such as a copper-oxide rectifier or an electronic discharge device such as a hot-cathode gas diode, or like elements. It may be necessary, due to voltage drops in such unilateral or unidirectional devices or elements or due to higher voltages being necessary for conduction therethrough as compared to the operating paths of the register relays, to insert resistance in the operating leads, such as H and it, to limit operating current of register relays, each relay provided with a when batteries, such as I! and 22, must be larger than normally required in relay operating circuits. When asymmetrical resistances, such as copper-oxide rectifier 2!, are used it is not considered necessary to provide such higher voltages. However, the use of comparable devices, such as gas tubes, adds the requirement, generally, of higher voltage ranges.
