CLASS 21 a3: 67 / INT. CLASS H 04 m PATENT PERIOD FROM 11 FEBRUARY 1955 PROVIDED ON 14 FEBRUARY 1963 PUBLISHED ON 21 MAY 1963 Ans. 1274/1955 den 11/2 195Heirtill tat 'ritnin gar X I L SKOOG, STOCKHOLM Electronic coupling device with gas discharge tubes connected in chain The present invention relates to electronic coupling devices, e.g. For impulse counting devices, comprising a number of gas discharge tubes arranged with anode, cathode and tooth electrode, connected in a chain so that they sequentially turn on input pulses which are pressed some or all of the tubes simultaneously (rudder chain), the anodes of the tubes being connected to a at least one capacitance, whereby the slackening circuit after a certain time automatically achieves sidelining of the rudder regardless of whether something else is toothed or toothed.

Tidigare utfOringsformer av dylika anordningar ha joke kunnat mottaga pulser med hogre stegningshastigheter per sek. anc:a 1500. Eftersom man fordrar att endast ett ror i taget skall vara tant har hittills rorens avjoniseringstid begransat hastigheten (exempelvis 1000 steg/sek. for vissa moderna rortyper). Previous embodiments of such devices have jokingly been able to receive pulses with higher step rates per second. anc: a 1500. Since it is required that only one rudder at a time should be aunt, so far the rudder deionization time has limited the speed (for example 1000 steps / sec. for certain modern rudder types).

I anordningen enligt foreliggande uppfinning är hastigheten for mottagning av impulser oberoende av gasurladdningsrorens avjoniseringstid och impulser kunna mottagas med en hastighet som bestammes endast av rorens joniseringstid, vilken är endast en brakdel av avjoniseringstiden i hittills kanda gasurladdningsror. Vid en utforingsform av uppfinningen blir mottagningshastigheten for impulser till och med oberoende av joniseringstiden. Betecknande for uppfinningen Sr ocksa att i motsats till tidigare kanda elektroniska kedjor en impuls fran en 1 kedjan ingaende krets kan erhallas, vars langd i tiden Sr oberoende av impulseringshastigheten, varigenom god tids. In the device according to the present invention, the rate of receiving pulses is independent of the deionization time of the gas discharge tubes and pulses can be received at a rate determined only by the ionization time of the tubes, which is only a fraction of the deionization time in hitherto known gas discharge tubes. In one embodiment of the invention, the reception rate of pulses becomes independent of the ionization time. Significant to the invention is also that, in contrast to previously known electronic chains, an impulse can be obtained from a circuit entering the chain, the length of which in time is independent of the pulsation speed, whereby a good time.

Det vasentligt nya i anordningen enligt uppfinningen är att fOrspanning till ett rdrs tandelektrod uttages frail nagot foregaende rors huvudelektrodkrets (katod) i serie, med ett icke-linj art element pa sadant satt all en kondensator kopplad till tandelektroden laddas och uppehaller fOrspanning nar foregaende rOr slaekes och varvid tandning av efterfoljande rOr sker genom att yttre triggerimpulser tillfores kondensatorns ena poi via en ingang och varvid vardet av fOrspanning och amplitud hos triggerimpulsen arc sh valda att spanningen pa respektive tandelektrod blir tillracklig for att tanda Uppfinningen heskrives narmare i samband med ritningarna, It vilka fig. la, lb visa en ny resp. en kand enhet for en slackningskrets med ett gasurladdningsrot., fig. 2 ett tandspanningsdiagram for glimtrioder, fig. 3 en kedja av elektronror med en krets enligt fig. la, fig. 4 en kedja av elektronror med slackningskrets enligt uppfinningen, fig. 5 en kedja av elektronror med en del av huvudelektrodkretsen gemensam for na.gra ror saint fig. 6 tva elektronrorskedjor, kopplade i dekader flied en kedja enligt uppfinningen. The essential novelty of the device according to the invention is that bias voltage to a tube of the tooth electrode is taken from the main electrode circuit (cathode) of the preceding tube in series, with a non-linear element so that all a capacitor connected to the tooth electrode is charged and sustains bias voltage. and wherein ignition of subsequent tubes takes place by supplying external trigger pulses to one poi of the capacitor via an input and wherein the value of bias and amplitude of the trigger pulse arc sh causes the voltage on each tooth electrode to be sufficient to ignite. Fig. 1a, 1b show a new resp. Fig. 2 shows a toothed voltage diagram for spark plugs, Fig. 3 a chain of electron tubes with a circuit according to Fig. 1a, Fig. 4 a chain of electron tubes with a slack circuit according to the invention, Fig. 5 a chain of electron tubes with a part of the main electrode circuit common to some tubes saint fig. 6 two electron tube chains, connected for decades flied a chain according to the invention.

Tva kretsar med sjalvslackande enheter visas som exempel i fig. la och lb. I kopplingen enligt fig. la ingar en svangningskrets LCB och nar ett gasurladdningsror G, tander, fag en strom genom roret med dampad svangning (av formeln k.Ve--`". sin fit). I formeln betyder k en konstant, V en spanning, a en dampningskonstant och ,8 egenvinkelfrekvensen for dampad krets och I tiden. Det inses latt att vid en miss tidpunkt gar strommen mot 0 och roret slocknar. Two circuits with self-leaching units are shown as examples in Figs. 1a and 1b. In the coupling according to FIG. voltage, a a damping constant and, 8 the natural angular frequency of the steamed circuit and In time It is easy to see that at a wrong time the current goes towards 0 and the rudder goes out.

I fig. 2 visas exempel pa tandspanningsdiagram for olika typer av gEmtrioder. Ordinatan anger anodspanning V och abskissan hjalpanodspanningen 17.volt. Katoden har potentialen noll. Del a av kurvan anger tandspanningen fran hjalpanod till katod (riktning plus till minus), del b Iran anod till katod, del c fran anod till lajalpanod, del d frail katod till hjalpanod, del e frail katod till anod samt del f fran hjalpanod till anod. Det av den inre kurvan omslutna vita omradet anger Arens icke-ledande spanningsomrade dvs. dar de icke tander, det sektionerade omrade, Mom vilket roren Under. Fig. 2 shows examples of tooth tension diagrams for different types of gemtriodes. The ordinate indicates the anode voltage V and the abscess the auxiliary anode voltage 17.volts. The cathode has the potential zero. Part a of the curve indicates the tooth tension from auxiliary anode to cathode (direction plus to minus), part b Iran anode to cathode, part c from anode to a loyal cathode, part d frail cathode to auxiliary anode, part e frail cathode to anode and part f from auxiliary anode to anode. The white area enclosed by the inner curve indicates the non-conductive voltage range of the Arena, ie. where they do not tander, the sectioned area, Mom which the rudder Under.

Da kandensatorn C i svangningskretsen enligt fig. lavid rorets slackning ar helt urladdad eller laddad med mots att polaritet (hero- 2— — ende ph. dam.pningen) maste C aterappladdas enligt fig. la via R2 for att G1 skall kunna tanda pa nytt. Tiden for str8mmens varaktighet kan godtyckligt varieras genona andring av L eller C och i viss man genom andring av Ri. Since the capacitor C in the oscillation circuit according to Fig. Lavid tube slack is completely discharged or charged with the opposite polarity (heroic ph. Steam opening), C must be recharged according to Fig. . The time for the duration of the current can be arbitrarily varied by changing L or C and to some extent by changing Ri.

Kretsen enligt fig. lb med motstand R1 R2, ett gasurladdningsror G2 och en kondensator finnes tidigare beskriven och gar allmant under namnet vippkoppling eller vipposcillator. Dess anvandning i samband med uppfinningen omnamnes senare. The circuit of Fig. 1b with resistor R1 R2, a gas discharge tube G2 and a capacitor is previously described and is generally referred to as the toggle coupling or toggle oscillator. Its use in connection with the invention is mentioned later.

I fig. 3 som visar en kedja av elektronror G1—G„ med en gemensam pulsingang P, an.- vandes kretsen enligt fig. la, men en. anordning enligt fig. lbkan givetvis aven anvandas liksom variationer av dessa olika kretsar. In Fig. 3, which shows a chain of electron tubes G1 — G „with a common pulse input P, the circuit according to Fig. 1a, but one. device according to Fig. 1b can of course also be used as well as variations of these different circuits.

Urladdningsroret G, tander pa den forsta imp-ulsen fran en pulskalla Pin t. ex. en pulsgenerator, eller ocksa harrorande fran en annan rorkedja. Over motstandet 11.1 fas d, som tidigare forklarats, en spanningsimpuls av nfirmast en halv period av en sinusvag. Deana spanning laddar upp kondensatorn et(2) till ett sadant varde att roret G2 ej tander enbart pd derma Mrspanning. Nar andra impulsen kommer frau kallan Pi,, bverlagras denna pa forspanningen och roret G2 Milder, varefter Mrloppet enligt ovan upprepas och G3—G„ tan-der i tur och ordning. Pulserna fran Pin gar avenledes in pa ovriga rors tandstrackor, men da forspaiming saknas, tanda de joke. Det inses latt att impulshastigheten endast begransas av joniseringstiden plus uppladdningstiden Mr den kondensator Ct, som tillhor rorkretsen, vars ror harnast skall tandas. Ned-at begransas hastigheten av att C, ej far urladdas for mycket innan nasta impuls kommer. Inforandet av likriktare L1 enligt fig. 3 vidgar hastighetsgransema betydligt da likriktaren ger kort uppladdningstid for C genom .sitt laga frammotstan.d, resp. lang urladdningstid genom sitt hOga backmotstand. Ater- uppladdning av Csker i detta fall Over 112. The discharge tube G, teeth on the first impulse from a pulse-cold Pin e.g. a pulse generator, or also rumbling from another rudder chain. Over the resistor 11.1 phase d, as previously explained, a voltage pulse of at least half a period of a sine wave. This voltage charges the capacitor one (2) to such an extent that the tube G2 does not turn on only this voltage. When the second impulse comes from the cold Pi ,, this is superimposed on the bias and tube G2 Milder, after which the race as above is repeated and G3 — G „turns in turn. The pulses from Pin go differently on the other pipes' tooth rungs, but when there is no foreplay, they joke. It is readily appreciated that the pulse rate is limited only by the ionization time plus the charging time Mr the capacitor Ct, which belongs to the rudder circuit, whose rudder is to be toothed. The speed is limited by the fact that C, must not be discharged too much before the next impulse arrives. The introduction of rectifier L1 according to Fig. 3 widens the speed limits considerably as the rectifier gives a short charging time for C through its low forward resistance, resp. long discharge time due to its high hill resistance. Recharging of Csker in this case Over 112.

I fig. 4 visas en rorkedja med gasurladdningsror G1—G6 med flera ingangar, exempelvis tre sadana P1, P2, P3, varjamte aver' en annan ateruppladdningsprincip for kondensatorer C1—0 visas. I motsats till forhallandet vid fig. 3, ger ror G1 barspanning till G3 :s kondensator Ct3 i G2 till G4:8 kondensator Ct4 osv. varfor man exempelvis vid (l :s tandning ej behover vanta ph. att G2 skall uppladda Ct3, da ju detta gjorts av G1. Den ovan namnda hastighetsbegransande uppladdningstiden har salunda eliminerats. Forsta pulsen kommer pa ingang P1. Roret G1 tander (startforspanning) och laddar upp kondensatorn C och sa snart denna uppladdning Or klar kan pulsen ingang P3 tillatas komma. Pals frail in-gang P2 Under roret G2 (startforspanning) soin laddar app Ct4, varefter en ny pals kan tillatas komma pa. ingang Pi. Pals fran ingang P3 Ender ror G3 :som laddar upp Ct5, varvid puls frail ingang P2 kan anyo komma osv. Ar Ct3:s uppladdningstid liten, fas i detta fall c:a its per steg, vilket ger 100000 steg/s. Givetvis stalles i detta extrema fall stora krav pa impulsernas utseende jarate kretsens dimensionering. Fig. 4 shows a rudder chain with gas discharge tubes G1-G6 with several inputs, for example three such P1, P2, P3, and a different recharging principle for capacitors C1-0 is shown. In contrast to the ratio at Fig. 3, rudder G1 provides bar voltage to G3's capacitor Ct3 in G2 to G4: 8 capacitor Ct4 and so on. why, for example, in the case of (1: s ignition, there is no need to wait for G2 to charge Ct3, since this is done by G1. The above-mentioned speed-limiting charging time has thus been eliminated. The first pulse comes at input P1. charges the capacitor C and as soon as this charge is completed Or the pulse input P3 can be allowed to come in. P3 Ender ror G3: which charges Ct5, whereby pulse frail input P2 can anyo come, etc. Is Ct3's charging time small, phase in this case approx. Its per step, which gives 100000 steps / s. Of course stalls in this extreme cases great demands on the appearance of the impulses jarate the dimensioning of the circuit.

I samma fig. 4 visas en Leruppladdningskrets •som drives exempelvis av en. bistabil kopplingsanordning t. ex. en glimrorsvippa, varvid glimrorens anoder Or anslutna till Al och A2. R8ren G1—G3 Oro anslutna till en kopplingstrad Al och roren G4—G6 till en kopplingstrad A2. Traden Al har normalt en h5g spanning som laddar upp motsvarande kondensator C1-3 till lamplig spanning. Pa forsta impulsen eller nar G tander dras Al :s spanning ned till en potential som Or lagre an nagot rors brinnspanning. Laddningen kvarHiles pa C1-3 genom likritare L2, sa. att C1-3:s laddning Or nara nog konstant. I samman ogonblick eller vid nagon annan narbelagen tidpunkt hojs spanningen ph trad A2 sa att rorens G4—G6 kondensatorer C4—C6 uppladdas. Nar G3 eller nagot av de tidigare roren (G1 eller G2) tant, dras A2 :s spanning 'aterigen ned, varefter Al :s spanning hojes ph nytt. Vippan kan manovreras Iran de i kedjan ingaende rtiren G1—G6, varvid god overensstammelse i tid for vippningen kan erhallas. Fordelen med denna utforingsform Or att den pa. grand av forbattrad kurvform for ateruppladdningen av kondensatorerna G1C Or snabbare an R—C aterstallningen dvs. flax C1-6 uppladdas via ett motstand R3. Detta Or av betydelse for snabba rorkedjor, kopplade I ring, eller vid brutna rorkedjor, som Onskas arbeta vid tatt atellkommande impulsserier. Fig. 4 shows a clay charging circuit • which is driven, for example, by a. bistable coupling device e.g. a glitter flip-flop, the glow anodes Or being connected to A1 and A2. R8s G1 — G3 Concerns connected to a connecting line A1 and rudders G4 — G6 to a connecting line A2. The line A1 normally has a h5g voltage which charges the corresponding capacitor C1-3 to lamp voltage. On the first impulse or when G teeth, Al's voltage is reduced to a potential that Or stores at some tube's burning voltage. The charge remainsHiles on C1-3 through rectifier L2, so. that C1-3's charge Or nara enough constant. At the same moment or at any other nearby time, the voltage ph trad A2 rises so that the rudder G4 — G6 capacitors C4 — C6 are charged. When G3 or some of the previous rudders (G1 or G2) tant, A2's voltage is again reduced, after which A1's voltage is raised ph again. The rocker can be maneuvered in the chain-engaging return G1-G6, whereby good agreement in time for the rocker can be obtained. The advantage of this embodiment is that it pa. grand of improved curve shape for the recharging of the capacitors G1C Or faster than the R-C recovery ie. flax C1-6 is charged via a resistor R3. This is of importance for fast rudder chains, connected in a ring, or in the case of broken rudder chains, which Onska's work with in the coming impulse series.

I fig. 6 visas tvh rorkedjor kopplade i dekader, varav den forsta med tie elektronrOr G av den typ uppfinningen hanfor sig till. Nar forsta rorkedjan mottagit 10 pulsar (Pin) stegar den kedja nummer 2 med ho elektronror T1—T ett steg framat, efter ytterligare 10 pulser ytterligare ett steg osv. Fig. 6 shows two rudder chains connected for decades, the first of which is connected to the electron tube G of the type of the invention. When the first rudder chain has received 10 pulses (Pin), the chain number 2 rises with ho electron tubes T1 — T one step forward, after another 10 pulses another step, and so on.
