Description

Uppfinnare: S NI Brouwer Prioritet begurd treat den 4 jurd 1958 (Nederlunderna) Foreliggande uppfinning hanfor sig till en anordning for undersOkning av tal med avseende pa narvaron av signifikativa siffergrupper, vilkas siffror kunna forekomma i tva eller flera positioner (sifferlagen). Inventor: S NI Brouwer Priority begurd treat on 4 jurd 1958 (Netherlands) The present invention relates to a device for examining numbers with respect to the presence of significant groups of digits, the digits of which may occur in two or more positions (the law of numbers).

Sadana anordningar kunna exempelvis anvand'as i automatiska telefonisystem f or b estimning air taxezonen med utgangspunkt fran det valda riktnumret. I vanliga tid-zon-overf8- ringsanordningar anvandes for detta andamal en kaskadkoppling av valjare, vars olika steg installas genom de pa varandra foljande siffrorna i riktnumret. Denna app arat Or mycket dyr och skrymmande. Such devices can, for example, be used in automatic telephony systems for estimating the air taxi zone based on the selected area code. In ordinary time-zone transmission devices a cascade connection of selectors is used for this purpose, the different steps of which are installed by the successive digits in the area code. This app arat Or very expensive and bulky.

Inona telefonin finns det ocksa manga andra fall, varvid vissa kopplingsman.ovrer skola genomfOras vid upptradan.det av bestamda siffengrupper i ett valt nummer, varfor detta nummer maste undersokas med avseende pa narvaron av de aktuella siffergrupperna. Nagra exempel skola givas: Frankoppling av vissa apparater, sasom impulssandare eller impulsgeneratorer for omvandling av kriterier, som Oro installda me-deist tryckknappar, till impulsgrupper efter mottagning av den .sista sill ran, for vilket liii- damOl fran det valda riktnumret maste aidedas hur manga siffror totalt komma att väl- jas. In telephony, there are also many other cases in which certain switchgear must be carried out when certain groups of digits appear in a selected number, so this number must be examined with regard to the presence of the relevant groups of digits. Some examples should be given: Disconnection of certain devices, such as impulse transmitters or impulse generators for conversion of criteria, such as Oro installed with push buttons, to impulse groups after receiving the last herring, for which liii- damOl from the selected area code must be aidedas how many figures in total will be chosen.

Inkoppling av en upptagettongenerator eller en nedkopplingsanordning genom val av ett icke existerande nummer. Connection of a busy tone generator or a disconnection device by selecting a non-existent number.

Omkoppling till en tvarforbindning, om det vid det valda riktnumret visar sig, att samtalet joke behover ledas Over en zontaxeanordning. Switching to a cross-connection, if it turns out at the selected area code that the call joke needs to be routed via a zontax device.

Dessutom firms det ocksa mom andra grenar av tekniken behov av medel, genom vilka kan faststallas, om vissa bestamda siffergrupper forekomma i ett visst tal, t. ex. vid bearbetning av statistiska data med hjalp av halkortsmaskiner. In addition, there are also other branches of technology in need of means by which it can be determined whether certain specific groups of numbers occur in a certain number, e.g. when processing statistical data with the help of slip card machines.

Uppfinningen avser att ange en enkel och billig anordning, medelst vilken tal f8r samtliga namnda andamal kunna undersokas med avseende pa narvaron av signifikativa siffergrupper. The invention intends to provide a simple and inexpensive device, by means of which numbers for all the aforesaid purposes can be examined with respect to the presence of significant groups of digits.

Enligt uppfinningen Or en rad av ferromagnetiska karnor med tva magnetiseringstillstand anordnad for varje position, varvid karnorna i den forsta raden frau borjan befinna sig i ett visst (positivt) magnetiseringstillstand, medan karnorna i de avriga raderna Iran borjan befinna sig i motsatt (negativt) magnetiseringstillstand. Efter mottagning av varje siffra i det tal, som skall undersokas, tillfores en strom till en ledare, som Or kopplad med samtliga karnor i den med siffrans position overensstammande raden, samt ocksa till en ledare, som motsvarar siffrans varde och Or kopplad rued karnorna i de olika raderna enligt ett schema, rsom Or bestamt genom sammansattningen av de signifikativa siffergrupperna, sa att en eller flera karnor i den aktuella raden, savitt dessa karnor befinna sig I positivt magnetiseringstillstand, overforas till negativt magnetiseringstillstand och darvid medelst en forskjutningskrets antingen styra ett organ for faststallande av ett kriterium eller overfora en eller flera karnor i nista rad till positivt magnetiseringstillstand. According to the invention, Or a row of ferromagnetic cores with two magnetization states arranged for each position, the cores in the first row from the beginning being in a certain (positive) magnetization state, while the cores in the other rows Iran are initially in an opposite (negative) magnetization state . After receiving each digit in the number to be examined, a current is supplied to a conductor, which Or is connected to all the nuclei in the row corresponding to the position of the digit, and also to a conductor corresponding to the value of the digit and Or connected to the rued nuclei in the different rows according to a scheme, which Or determined by the composition of the significant groups of numbers, said that one or more nuclei in the current row, as long as these nuclei are in a positive magnetization state, are transferred to a negative magnetization state and thereby by means of a shift circuit either control a means for establishing a criterion or transferring one or more nuclei in the next row to a positive magnetization state.

Uttrycket »rader» tjanar darvid endast till att ange, att flera karnor Oro tillordnade varje position, och behover icke betyda, att karnorna Oro geometriskt grupperade i rader. Uttrycken qmsitiv» och »negatiw tjana endast att atskilja larnornas hada magnetiseringstillstand och hanfora sig icke till riktningen has kraftlinjerna. The expression "rows" then only serves to indicate that several nuclei Oro assigned each position, and need not mean that the nuclei Oro are geometrically grouped in rows. The terms "positive" and "negative" serve only to separate the magnetized state of the larvae and do not move in the direction of the lines of force.

Vid en lamplig utforingsform av anordning- 2— — en overfOras karnorna till begynnelsetillstandet genom tillforande av en stromimpuls till en eller flera aterstallningsledare, som ar (aro) kopplad (kopplade) med karnorna i den forsta raden pa visst salt oeh med karnorna i de ovriga raderna p motsatt att. In a suitable embodiment of the device, the cores are transferred to the initial state by applying a current pulse to one or more recovery conductors, which are (aro) connected (connected) to the cores in the first row on a certain salt and to the cores in the other the lines on the opposite that.

Den ledare, som ãr kopplad med samtliga karnor i den med siffrans position Overensstammande raden, kan inkopplas medelst en positionsstrinnstallare, som stegar fram ett steg vid mottagning av varje siffra. Denna stromstallare kan vara utformad som en vridstromstallare men ocksa som en styranordning med relakontakter, elektronror eller transistorer. The conductor, which is connected to all the cores in the row corresponding to the position of the digit, can be connected by means of a position stepper, which steps forward one step when receiving each digit. This switch can be designed as a rotary switch but also as a control device with relay contacts, electron tubes or transistors.

For inkoppling av den ledare, som overensstammer med siffrans varde, kan faretradesvis en siffervaljare anvandas, vilken installes pa nytt av varje siffra i det tal, som skall unders8kas. Denna valjare kan vara utformad som en yridstromstallare men aven som en styranordning med relakontakter, elektronror eller transistorer. To connect the conductor, which corresponds to the value of the number, a number selector can be used in danger, which is re-installed by each number in the number to be examined. This selector can be designed as a yrid current switch but also as a control device with relay contacts, electron tubes or transistors.

Sarskilt fordelaktig fir en utformning, vid Aiken de fran positionsstromstallaren vanda andarna av de ledare, som vardera aro kopplade med alla karnorna i en viss rad, aro forbundna med siffervaljarens ingangsklamma Over en gemensam ledare, sa att en strOmimpuIs, som efter mottagning av siffran tillf5res positionsstr8mstallaren, successivt genomloper de med siffrans position och varde motsvarande ledarna. Particularly advantageous for a design, at Aiken the from the position switch are the spirits of the conductors, each of which is connected to all the cores in a certain row, are connected to the input terminal of the numerator Over a common conductor, so that a current impulse, which after receiving the digit is supplied the position switch, they successively traverse the position of the digit and become the corresponding conductors.

Organen for faststallande av kriterierna kunna foretradesvis likaledes besta av ferromagnetiska karnor med tva stabila magnetiseringslillstand, vilka karnor frfin biirj an befinna sig i negativt magnetiseringstillstand och vardera kunna overforas till positivt magnetiseringstillstand medelst en eller flera av de namnda fOrskjutningskretsarna. Dessa karnor kunna da aterforas till begynnelsetillstandet med samma medel som de avriga karnorna, sedan undersokningen av talet fir avslutad. The means for determining the criteria may preferably also consist of ferromagnetic nuclei with two stable magnetization states, which nuclei are preferably in a negative magnetization state and can each be transferred to a positive magnetization state by means of one or more of the said displacement circuits. These nuclei can then be returned to the initial state by the same means as the other nuclei, after the examination of the number has been completed.

Uppfinningen forklaras nu nOrmare under hanvisning till bifogade ritning, som visar ett utforingsexempel av en anordning enligt uppfinningen. The invention will now be explained in more detail with reference to the accompanying drawing, which shows an embodiment of a device according to the invention.

Det antages, att kopplingen skall anvandas i Amsterdams telefonnat, fOr vilket foljande zonindelning galler: Zon A: de system, vilkas nummer borj a med siffergrupperna 290 och 296. The connection shown is intended for determining the tariff zones based on the selected area code for automatic interurban telephone calls. It is assumed that the connection will be used in Amsterdam's telephone network, for which the following zoning applies: Zone A: the systems whose numbers start with the number groups 290 and 296.

Zon B: de system, vilkas nummer bola med siffergrupperna 250, 251, 252, 254, 255, 256, 294, 295, 297, 298 och 299. Zone B: the systems whose numbers bola with the numerical groups 250, 251, 252, 254, 255, 256, 294, 295, 297, 298 and 299.

Zon C: de system, vilkas nummer harj a med siffergrupperna 1, 22, 253, 3, 4, 5, 6 och 8. Zone C: the systems whose numbers have the groups 1, 22, 253, 3, 4, 5, 6 and 8.

De namnda 21 siffergrupperna utgOra alltsa de signifikativa siffergrupperna, som avses i foreliggande fall. De innehalla maximalt tre siffror, dvs. siffrorna 1 de signifikativa siffergrupperna kunna forekomma i positionerna 1, 2 och 3. The above-mentioned 21 groups of figures thus constitute the significant groups of figures referred to in the present case. They contain a maximum of three digits, ie. digits 1 the significant groups of digits may occur in positions 1, 2 and 3.

Ar den andra siffran 9, sker detta med kamorna K33 och K34 via karnans K23 forskjutningskrets. Siffervaljaren GS aterstalles darefter till utgangstillstandet. From the beginning, the cores K11 and 1 (12) are in a positive magnetization state, while all 5 other cores are in a negative magnetization state. Upon receipt of the first digit in the area code, the numeric switch CS is installed in the corresponding position, the position switch PS Or connecting a bracket and so on. conductor L1 Darph is supplied with a current pulse via terminal A, which is conducted from the tensioner PS through the conductors L1 and M to the number selector CS and thence via the conductor N corresponding to the selected number to the ground wire E. The current flowing through the conductor L1 and the current conductor N Or in and for itself too weak for the magnetization state of the other nuclei.A change of the magnetization state can take place only if the said currents coincide.If the first digit in the area code now Or equal to 1, 3, 4, 5, 6 or 8 , this coincidence occurs for karnan K11, which is all transmitted from a positive to a negative magnetization state. an offset circuit connected to the core 1 (11) in function, sh that the criterion core KC is transferred from negative to positive magnetization state and thus achieves the criterion for taxon zone C. The other digits in the area code Oro since the meaning of the zonal determination. If the first digit in the area code 2 appears, then the coincidence of the nucleus K12 appears, and all of it is transferred to a negative state, whereby the nuclei K21, 1 (22 and 1 (23) are transferred from negative to a positive state by means of the current displacement circuit. When the second digit is received, the digit selector ph is installed again, whereby the position switch PS Or is one step. A current pulse is then applied to the conductor L2 via the terminal A and via the conductor M to the conductor N corresponding to the selected digit. Koinciden.sen occurs dO for karnan K21, for the chosen number Or 2, for karnan 1 (22, for the chosen number Or 5 and for karnan 1 (23, if the chosen number Or 9. If the first number was 1, 3, 4, 5, 6 or 8, the coincidence becomes ineffective, since the nuclei.a 1 (21, K22 and K23 dO are in a negative state. However, the first digit has been 2, sh that the named nuclei are enter into a positive state, the vessel in which the coincidence occurs is returned to a negative state. In the latter case, the second digit 2, 8, the criterion kernel KC is transferred to a positive state via the kernel 1 (21 displacement circuit, so that the criterion for the tax zone C is met. The third digit Or di is insignificant for the zone 4, - stuttering. Is the second digit 5, If the cores K31 and K32 are transferred to a positive state via the displacement circuit of the core K22.If the second digit is 9, this is done with the cams K33 and K34 via the displacement circuit of the core K23.The number selector GS is then reset to the initial state.

Vid mottagning av den tredje siffran installes siffervalj area pa nytt, varvid positionsstromstallaren PS ater stegar fram ett steg. StrOmimpulsen tillfores d& ledaren L3. En koincidens intraffar for karnan K31, om den tredje siffran Sr 0, 1, 2, 4, 5 eller 6, for karnan K32, om den tredje siffran Sr 3, Or karnan K33 om den tredje siffran Sr 6 eller 0, och for karnan K34, om den tredje siffran Sr 4, 5, 7, 8 eller 9. Bilda de hada forsta siffrorna i siffergruppen 25, overfares alltsa kriteriekarnan KB till positivt tillstand, om den tredje siffran Sr 0, 1, 2, 4, 5 eller 6, och detsamma galler kriteriekarnan KC, om den tredje siffran Sr 3. Bilda de bhda forsta siffrorna gruppen 29, overfares kriteriekaman KA till positivt tillstand, om den tredje siffran är 0 eller 6, medan detsamma galler far kriteriekarnan KB, om den tredje siffran Sr 4, 5, 7, 8 eller 9. For samtliga ovriga varden av de hada forsta siffrorna blir koincidensen utan verkan. Nu har alltsa zonkriteriet astadkommits Sven for de fall, da. riktnumret borjade med siffrorna 2'5 eller 29. Siffervaljaren CS kan sedan, om sS Onskas, sattas ur drift. Upon receipt of the third digit, the digit selection area is re-installed, whereby the position switch PS again steps forward one step. The current pulse is applied to the conductor L3. A coincidence occurs for karnan K31, if the third digit Sr 0, 1, 2, 4, 5 or 6, for karnan K32, for the third digit Sr 3, Or karnan K33 for the third digit Sr 6 or 0, and for karnan K34, if the third digit Sr 4, 5, 7, 8 or 9. Form the hada first digits in the digit group 25, then the criterion core KB is transferred to a positive state, if the third digit Sr 0, 1, 2, 4, 5 or 6 , and the same grid the criterion kernel KC, if the third digit Sr 3. Form the bhda first digits group 29, the criterion chamber KA is transferred to a positive state, if the third digit is 0 or 6, while the same grid receives the criterion kernel KB, if the third digit Sr 4, 5, 7, 8 or 9. For all other values of the hada first digits, the coincidence becomes without effect. Now the zone criterion has been met with Sven for those cases, then. the area code started with the numbers 2'5 or 29. The number selector CS can then, if sS is desired, be put out of operation.

For att asterstalla kopplingsanordningen till det ursprungliga laget efter samtalets slut eller efter overforandet av zonkriteriet till en tidmatningsapparat slutes strOmstallaren TS, varph en aterstallningsimpids tillfores klamman B. Denna aterstallningsimpuls Ater-far karnan Kit respektive K12 till positivt till-stand och samtliga &riga karnor till negativt tillstand. Om en eller flera forskjutningskretsar darvid sittas i funktion, elimineras dess respektive deras effekt genom den i ledaren T forefintliga strommen. To restore the switching device to the original state after the end of the call or after the transfer of the zone criterion to a time-feeding device, the switch TS is closed, whereupon a recovery impedance is applied to terminal B. This recovery pulse returns the Kit Kit and K12 to the positive state and all other points to the negative. condition. If one or more offset circuits are in operation, their respective their effect is eliminated by the current present in the conductor T.
