Description

Calculating machine with division device The well-known division machines operate with continued subtraction of the divisor from each partial dividend up to to exhaust each partial dividend or to a residual amount, which is the divisor falls below, whereupon each time the position of the divisor is shifted opposite your dividends the subtraction machine games will continue in the same way. Depending on the type of machine, each must go through the last subtraction machine game resulting residual formation a correction can be made from one or two additional N '(machine games, so that the total number of machines for the calculation machine games required for a division task at an average of five plus one or two correction steps per quotient position lies.

It is true that division machines are known which have facilities in order to make the '.machine independent of the requirement of the correction passes, whereby with every remainder it is determined immediately and automatically that the divisor exceeds the remaining amount and consequently the job relocation is carried out will. But even with this type of division machine, the number of division machines has to be used Machine games are still relatively high, because they are also on average five per quotient digit.

The invention aims to make the number of division machine games significant and uses a so-called quotient finder and a Multiplication device with single items, which are essential additional components are to be built into the machine of a conventional design and make it possible to per quotient position with only two machine games, namely for the formation of the product from the divisor and the respective quotient position, from = get. According to this, the quotient searcher determines from the highest digits of the Dividends and divisors the highest quotient digit in each case. With this single digit Quotient, the divisor is then multiplied in the multiplication device and the product of the respective dividend by means of a conventional transfer device subtracted. The same procedure is repeated with the remainder of the dividend until the dividend is exhausted.

According to the invention, a current or a Voltage comparators come into consideration. In the case of using the current comparator is provided with differential elements that respond to alternating current or direct current Differential relay worked, which here the selection of each to be made effective Make the single unit of the multiplier. Instead of the differential relay Electronic signals can be used, which enable an almost timeless comparison of numerical values between the divisor and the partial dividends.

The general idea of the invention is for electrical calculators and the purely mechanical system and should therefore be synonymous with both types of machines include. It can be used for key-operated calculators and those that are subject to taxation through counting or punch cards, in the latter case Machines can be used that not only use the initial values of a division calculation the punched cards, but also the calculation result, d. H. the quotient and, if applicable, the remaining balance, either in the task card itself or can be brought into a special card for perforation.

The standard equipment of a punch card tabulator machine are the following: i. The machine drive for the card transport, the counters and the writing mechanism with the electric motor 111 (Fig. I and 2); 2. the card sensing device with the upper and lower sensing brush sets OB and UB, each with 80 brushes and the card head coupling ring magnet KKM (FIG. 2); 3. the writing unit with the associated coupling magnet SK11 (FIG. 2) and the writing magnet SM associated with the individual writing positions (FIG. 3); 4. the operating elements B (FIG. I), such as keys T, control panel ST and manual switches S i to S 8; 5. the group control device R (Fig. R) with the group control relays GrR i to GrR 2o, the Untergrul) hen relay UGR and the group separation relay GR (Fig.2); 6. the contact devices K (Fig. R) with the cam contacts K i to K 24, the write contacts SK, the tens transmission contacts ZG 'and the clear contacts ZK and their control magnet I_: 11 (Fig. 2, 4 and 15).

The training and mode of operation of the aforementioned facilities result from the detailed description of the machine below.

B. The additional facilities required to perform divisional calculations are as follows: i. The three counters known per se for recording the dividend, the divisor and the quotient, each with ten counting positions i to io for the recording of the divisor, - ii to 20 for the quotient and 31 to 40 for the dividend (Fig. 4) . Each counter position is coupled by an addition magnet AM , either together at the beginning of a subtraction process, at 9, or at the time of the card sensing (counting) pulse, between 9 and i, during the addition process. The decoupling takes place either by means of the subtraction magnet SM through the counting pulse during the subtraction process or mechanically at the end of the addition process, with o. As a result, the total of the counter position is increased by an angle corresponding to the counting point value when adding, and by an angle corresponding to the associated false 9's complement when subtracting turned further. in position 9, each counter closes the (upper) 9-digit side of its ten-carry changeover contact ZK; when passing through o it closes and locks the (lower) o-side of ZK until after the tens carry over in the second half of the arithmetic game. For the tens transfer pulse, the switching connections between the associated adjacent counter positions are to be established by means of the switch panel sockets Zia; when subtracting, the first and last counter digits must also be connected to one another, e.g. B. digits 31 and 40 of the dividend counter as well as digits ii and 2o of the quotient counter for the transmission of the tens transfer pulse as an additional i for the production of the ioer complement from the false ger complement in the units digit. The tens carry pulse engages the next higher counter digit, and if this is at 9, also the next digit (continuous tens carry). The disengagement takes place mechanically after further rotation of the relevant total work station by an angle corresponding to the value i. The arithmetic value of each counter is given by its totalizer (see Fig. 6b, 7b), namely by preventing the lead contact of the point, the relevant pulse contact 9 to o by means of a pair of brushes on the coupled axis of the counter.

2. The quotient finder (AC and DC versions) for determining the highest point of the respective dividend ratio or dividend remainder to the divisor, d. H. i.e. the respective quotient position.

In the case of the subject matter of the invention, the dividend and divisor counter contained numerical values are compared with one another, namely z. B. each of the three highest digits of these numerical values, which are arranged with the help of parallel to each other Comparison resistors QS resistors (Fig. 5, 6a, 6h, 7a, 7b), which are used by the relevant Sum workplaces are switched on, in two current values of alternating or direct current implemented. For the highest digits of both counters to be compared are nine resistors each) i provided, the ohmic values of which are inversely related to the corresponding numerical values stand, i.e. for 9 the smallest, for i the 9-fold value (have. In addition, compared to the smallest one-thousandth resistances, the tens resistances iof the value and the unit resistances ioof the value. In the opposite proportion the corresponding currents are then associated with the ohmic values of the QS resistors of each meter, which are therefore proportional to the numerical values themselves. It will now be the ratio of the total current in the QS resistors of the dividend counter to the current in the Divisor-QS-Wi, resistance, i.e. the ratio of dividend to divisor itself, d. H. the quotient, determined with the help of current difference-sensitive Sehalt arrangements. Since the current ratio can be between the values i and 9; but only the highest Position of the quotient, i.e. an integer value that has not been rounded off is, eight differential arrangements through which the two currents flow become simultaneously cascaded, each of which is derived from a different exact integer Current ratio comes into operation. Because the specified resistance ratios The inherent resistance of the upstream differential arrangements applies to the total resistance taken into account when dimensioning the individual QS resistances.

In the alternating current version of the quotient finder according to FIG. 8 (see also FIG. 5), the differential elements each consist of a transformer T i with the transformation ratio i: i; whose primary windings connected in series are traversed by the dividend current, as well as a second transformer T 2 to T 9 with a transmission ratio equal to the ordinal number of the element (i: 2 to i: 9), whose primary windings are consecutively flowed by the divisor current. The secondary windings of both transformers each feed one winding of a polarized differential relay D 2 to D9 via a rectifier cell, in opposite directions. As a result, only those differential relays respond whose associated divisor carrier has a 'greater transmission ratio than the respective (alternating) current ratio, in which the effect of the alternating divisor current predominates.

In the Gleichstromausfarung the quotient finder according to Figure 8a pass the differential elements of polarized differential relay D 2 to D 9 with two oppositely acting windings the numbers of windings in the exact ratio of the ordinal number of the respective relays, thus in the ratio 2: i to 9: i stand, . The windings with the smaller number of turns are traversed by the (larger) current of the dividend QS resistors, those with the larger number of turns by the (smaller) current of the divisor QS resistors. Those relays whose transformation ratio is the same as the respective current ratio or less than the same - therefore remain at rest; only the relays, whose transformation ratio is greater than the current ratio, in which the effect of the divisor current predominates, switch their changeover contacts (D 2a to D 9a) to the position opposite to that shown, and this happens even with a very small deviation ( <i ° / o). As a result, the product relay coil PR with the next smaller ordinal number x i to x 9 (see FIG. 8) is switched on, which corresponds to the correct value of the quotient place and controls the quotient counter and the multiplication of the divisor with this quotient place. 3. The multiplication relay (disposable, Figure 9) for performing the known abbreviated multiplication of the respective quotient position determined by the quotient finder with the divisor, specifically for the separate determination of the right and left partial product, ie the units or tens of the Products of the individual divisor positions.

Nine product relays PRx i to x 9 are provided, which are designed as multi-wire contact relays of a known type and are provided with a maximum of i9 contacts each. They are controlled by the quotient finder, as described in Section 2 1> above. Via the contacts of the relay PR, the pulse contacts of the totalizer of the multiplier (divisor) counter are fed to the product pulses determined by the respective factor (quotient digit) instead of the normal counting pulses 9 to o, namely the units digits (right partial product) via the contacts x i R to x 9 R, the tens (left partial product) via the contacts x 2 L to x 9 L. The partial products are transferred from the sum of the divisor counter to the dividend counter.

The control organs, a) 9-series control as a safety measure for testing of the quotient determined by the quotient finder points to too great a value. Is namely If the quotient is too large by i, the product of the same and the divisor is greater than the dividend, so that after this product has been subtracted from the dividend a negative dividend remainder, i.e. H. complementary value remains, and therefore 'in the exaggerated dividend counter to the left of the highest digit used, nines appear instead of zeros. Accordingly, the device consists of one to the highest total number of the dividend counter, namely its 9-pulse contact, switched normal relay (9 relays, see Fig. 6a). It works in overdone Dividends the correction of the quotient by subtracting the value i and des Dividend remainder by adding the product (> times the divisor) in a special Correction mask'hinen.spiel.

b) Difference indicator to check the quotient for too small a value. After the subtraction. of the product of a quotient that is too small by i and the divisor of the dividend, the remainder of the dividend is incorrectly greater than the divisor. This criterion .must be. thus obtained by comparing the remainder of the dividend and the divisor, the comparison between the corresponding highest digits being decisive. For this purpose, similar to the quotient finder, the numerical value of each total workstation is converted into a corresponding current or voltage value with the help of ten comparison resistors DA resistors 9 to o per position, the ohmic values of which are reversed to the numerals. The resistors are connected to the ten pulse contacts of each total work station, whereby the resistors with the same numerical value are the same for all counter positions. The comparison of two total workplaces can now be done either by current comparison of the currents flowing in the associated comparison resistors, z. B. by means of differential relays similar to the DC version of the quotient finder or by comparing the Spaniltingsal> cases prevailing at the comparison resistors, z. 13. in a bridge circuit according to Fig. Io, consisting of the two relevant DA comparison resistors and two identical fixed resistors W i to W io or W i 'to 11'-io' and two parallel indicator branches, each consisting of one Bridge relays R XI to R XXIX or R XII to R XXVIII finitely upstream rectifier cell with oppositely polarized polarity in both branches. With appropriate polarity of the latter and the power source works z. 13. the relay group R XI to R XXIX, if the dividend is greater than the divisor. The bridge relay comparing the highest digits activates the differential display relay RI with its changeover contact (see Fig. Ii), which in turn causes the quotient to be corrected by adding an i and the dividend by subtracting the product (inial divisor) in a special correction game .

c) Difference indicator for checking the column switch setting. If the highest digit of the dividend or dividend remainder is smaller than that of the divisor, then the highest divisor digit must be assigned to the second highest dividend digit for the following determination of the quotient from both values, namely for the multiplication of the finite quotient of the divisor and the subtraction of the product of the dividends , ie the divisor can be shifted by one place to the right compared to the dividend. For this purpose, the purely digitized assignment of dividend to divisor (using the zero check, see section 4d) is followed by a check for correct value assignment with the aid of the difference indicator. The same comparison resistors DA resistance according to Fig. 6a to 71i, fixed resistors W i to .W 1o, ff 'i' to W io 'and bridge relays R XI to R XXI X, RXII liis RXXVIII according to Fig. Io are used, as in section 41) above. Only in this case comes the relay of the relays R XII to R XXVHI connected to the two highest value points into action, which with the help of a multiple contact relay, the correction relay VR 21, according to Fig. 11, a reversal of the column switches described in section 5 in the sense the required job shift. This happens with the column switch relays VR i 'to VR io', VR iö '(for the quotient searcher) by means of the contacts 1'R 21 I' to X ', as well as with the column switch relays VR ii to VR 20 (for the partial product and quotient transmission and for the difference indicator for quotient control) by means of contacts VR 21 I to X.

(1) o-control for presetting the column switch. For all Direct division arithmetic operations are always the highest digits of DIN-idend and Allocate divisors to each other if the dividend is greater than the divisor. There the number of zeros for the position of the highest value places in the summaries to the left is decisive, it serves as a criterion for the assignment. To this The purpose is at the time of the o-control according to Fig. 6 a and 7 a with the o-Imptile scoritact an o-relay R for each total work station of the dividend counter and the divisor counter I to R X or R 1 to R io of the usual type connected. Accordingly, the o-relays occur of all digits that contain a zero are in action, but switch to Fig. I i only those o-relays that go to the zeros immediately to the left belong to the highest value points, the corresponding column counters (see section 5) for the mutual assignment of these highest positions. A subsequent Correction of the column switch control in the event that the highest divisor is greater than the highest dividend digit, is shown by the difference indicator according to section 4c above.

5. The column switch, a) for the difference indicator to connect the feeder contacts of the ten total workplaces of the dividend, indirectly via the associated main distributor, with the ten differential indicator bridge circuits to control the column switch setting through contacts of the column switch relays V R ii to VR 2o in series with contacts from VR i to VR io (see Fig. io). These column switch relays -earth for the stated purpose according to FIG. Ii controlled by the o-relay contacts R ib to R io b and R 16 to RX b (see section 4d).

b) for the quotient finder to connect the two three groups of nine quotient finder resistors each QS @ resistors with the impulse contacts of the three highest cumulative workplaces of the dividend or the divisor, indirectly via the associated predistributor, according to Fig. 6a and 7 a to determine the quotient using the quotient finder differential elements connected to the QS resistors (see section 2). The connections are made through contacts of the column switch relays VR i 'to VR io', VR io "for the divisor and VR ii 'to VR 20' for the dividend, which are controlled according to Fig.ii also by the o-relays R i to R io or R 1 to RX and possibly also through the correction relay VR 21 .

c) for the subtraction transmission to connect the feeder contacts of the totaling stations of the divisor (indirectly via the associated main distributor, see Fig. 76), with the partial product switching sockets, which in turn are connected to the dividend counter stations via the addition subtraction boxes (see Fig. 4 ) for the purpose of subtracting the partial products (divisor times quotient), namely first the right, then the left partial product in the dividend counter: For this purpose, according to Fig. 12, further contacts of the column switch relays VR ii to VR 20 in series with further contacts of VR i are used up to VR io. The two correct column switch relays are also selected for these two work cycles by the o-relays or the correction relay (see section 56 and FIG. Ii). When the left partial product is transferred, the additional position shift of the same by one position to the left compared to the right partial product is effected by the contacts VRL XI to XX (see section 5 d).

d) for the multiplication for the connection of the pulse contacts of the sum workplaces of the divisor (indirectly via the pre-distributors "see Fig. 7b) either with the unit contacts xi R to - o te of the product relay PR for the transmission of the right partial product, @dh the units of the Individual products from divisor places multiplied by the quotient, or with the tens contacts x 2 L to x 9 L of the same product relay for the transmission of the left partial product, i.e. the individual product tens the contacts VRL II to IX.The direct connection of the divisor sums (outside, the multiplication) with the pulse generator of the counting pulses 9 to o via the contacts I to X of the relay VRN is required by the excitation of the latter during both multiplication transmissions VRR works on the first of the column switch relays VRR, VRL and VRN n Transfer play of the multiplication as well as any correction games, VRL in each case with the second multiplication game (s. Fig. 13).

e) for the quotient storage to connect the parallel connected Product relay contacts x i II to x 9 1I with the switching socket quotient (see Fig. 14), which are then sent to the quotient counters via the relevant addition sockets are placed (see Fig. 4). The connection is established by one more each Contact of the column switch relays VR i i to VR 2o in series with other contacts the relays VR i to VR io to during the transmission of the right sub-product the Value of the individual quotient places in the correct place in the quotient counter save. For the control of the column switch relays see Sections 5a and 5c.

6. The distribution facilities (pre-distribution and main distribution) for connection of each individual feed line and pulse contact of each individual point and of the Dividend and divisor sums with the necessary switching elements at the scheduled times of the work cycles (Fig. 6a, 6b and Fig. 7a, 7b). she can in a known manner, for. B. from commutators with fixed contact segments and rotating contact brushes exist with the timing indicated in FIG Contact distribution during a work cycle (machine revolution). Pre-distributor and main distributors are designed in the same way. There is one for each total workstation Pre-distributor required, for ten total workplaces each, d. H. for a complete register, a main distributor.

C. Operation of the machine: i. Commissioning. By inserting the main switch HS (Fig. 2) receives the coil of the sub-group control relay UGR Current in the following way: direct current source, main switch HS, fuse 4, relay coil UGR, contacts OKc and UKc, main switch HS, power source. This separates contact UGR opens the excitation circuit for coil GR of the group separation relay.

If the card magazine A (Fig. I) is loaded with the punch cards to be processed, the machine can be started. By closing the start contact (Fig. 2), the motor contactor MR and the control relay KR are connected to voltage: switch HS, fuse 2, relay coils MR and KR, start contact, stop contacts a and b, HS. MR switches on the drive motor M: HS, fuse i, motor 1'1T, MRa and b, HS. He sets the machine in motion. KR forms a holding circle with KRa for itself and MR : HS, fuse 2, MR, KR, KRa, point i, K io, HS or from point i via OKb or UKb or SKRa or RXc to point 2, stop contact b, HS. In addition, contact KRb closes the following circuit for the card head coupling magnet KKM: Fuse 5, KK, 11, coupling relay RK, contacts RYe, GRb, KRb according to point i, K io, HS. Contact RKa closes a hold circuit for itself and KKM via K i_3. The magnet KKM establishes the mechanical connection of the punch card transport and sensing device A (the card head) with the drive shaft of the machine by means of a claw coupling in a known manner. The machine thus executes a card feed game during which the first punch card is conveyed to the upper sensing brushes OB . Before the end of this machine game, K io (see FIG. 2) switches off the motor 11 and the magnet KK d1 via l1TR and KR. Also at the end (at about 324 °, see Fig. 15) of the first machine game, the first punch card closes the upper card lever contact OKK and thereby switches on the upper card lever relay OK , which closes its own holding circle with its contact OKa via K 13.

By pressing the start button again, the relays MR and KR are switched on again, but their hold circuit is now maintained via the contact OKb (or UKb) as long as cards are passing through. During the second machine game thus initiated, the first card is conveyed past the upper brushes OB to in front of the lower brushes UB. Since the contacts GrR i b to 2o b are still open, but contact OKc is already open, the sub-group control relay UGR is temporarily (up to about 265o) de-energized when K ii is interrupted (at about 23o °), but without its contact UGR to be able to excite the group separation relay GR via the still open contact UKK (blind Group separation). Just before the end of the second Machine game, the first card closes the un- lower card lever contact UKK, the lower Card lever relay UK with holding circuit via UKa and K 14 turns on. 2. Group control. This will happen automatically subsequent third machine game the first punch card from the lower brushes that second card at the same time from the upper brushes felt. Unless both sensed at the same time Cards contain the same group code holes, will be the ones with the upper and lower brushes (Fig. 2) connected, the corresponding card Group relays GrR i to 20 assigned to columns excited in the following way: fuse 3, speaking upper sensing bursts OB i to 8o, Switching sockets with switching cords, exciter lungs GYR i to 20, switch sockets with switch lace, corresponding lower sensing brushes UB i up to 8o, card pulse cam K 1, lower card lever contact UKK or LTKa and K i4, HS. the Group relays form a (lene holding circuits: Fuse 3, contacts GrR ia to 2o a, holding windings GrR i to 20, K 12, power source. Further hold them over by means of switching connections K ii contacts connected in parallel GrR ib to 2o b the excitation of the relay UGR and thus indirectly keeping the KK-11 upright, so that a Another card transport game follows immediately. When changing the group number, however remains the group relay GrR of the concerned Column de-energized and the associated b-contact open, so that when K ii is interrupted the relay UGR is de-energized and finite contact UGR that Group separation relay GReinsclialtet: fuseq, Contact UGR, GRa, coil GR, TTKK or UKa and K i4, HS. Relay GR stays above: safety tion 4, RYc, GRa working side up to arousal of the closing relay RY (Fig. ii) after completion of the Division. Contact GRb interrupts the pathogen circuit of the KKM card head coupling device, see above that the same through K 15 in the holding circle of the coupling, relay RK switched off, i.e. card transport and sensing is interrupted (group separation). 3. Inclusion of the calculated values in the counters and item writing. The output values (Divi- 1 dend and divisor) for the division calculation which in a known manner the punch cards one Card group taken, either as a final value or as partial values from which the Final values only through addition or subtraction forms are. The individual values are speaking counters (cf. section B i). You can also use them as usual written down in a list at the same time the (item writing). i For the purpose of storage, the corresponding value columns of the card lower sensing brushes Ljß (see Fig. 2) on the Control panel (see Fig. I; B. ST) with the relevant Addition-subtraction sockets of the counters i (see Fig. 4) connected, so for example UB 5i up to 6o with the Z; iülwerkstellen i to io (divisor) and UB 71 to 8o with the dividend counter digits 31 to 4o. The circuits for sensing the z. B. ten individual divisor positions for addition are: (see Fig. 4) fuse OK, addition magnets _411T i to io, write contacts SK i to io, tens transfer contacts ZÜ i to io, addition relay contacts RA i to io, addition-subtraction Buclisen i to io, connecting cords to sockets and l ', iirsteii UB 51 to 6o, (see Fig. 2) card pulse contact KI, UK K or UKa and K 14, HS. For the z.

In the case of negative values, a keyhole is used the punch card works in a known way the corresponding subtraction relay RB in place the addition relay R.4. The relevant counter then as a result of the closure of the Circuit: (see Fig. I) fuse, addition inagnete _4: 1I, write contacts SK, Z (7 contacts, lower subtraction relay contacts RB, K 18, (s.

The corresponding sub- The traction circuit for card sensing is: Fuse, Sul> traktionsmagneteSM, extinguishing contacts LK, lower addition relay contacts RA, addition Subtraction jacks and further as with addition. For the tens carry over into the relevant Counter digits come in at 223 ° in the second II of the "machine game (see Fig. 15, K 20) fol- The following circuits are established (see Fig. 4) Fuse, ALIl, SK, ZG contacts, counter contacts ZK, and although another OK page of the previous over- drawn position, K 2o, (see Fig. 2) point 2, stop contact b, HS. In the case of the continuous tens carry, z. B. from the second preceding position the neighboring position after sensing in position 9. Then there is the following circuit: (see Fig. 4) Fuse, Alll, SK, Zü-Kontakt upper 9-side of contact 7_K of the previous position, in addition parallel: .All, SK of the previous position, continue via ZZ contact to ZK io side of the second previous digit, K 2o, point 2, stop contact b, HS. For the purpose of simultaneous entry of items the writing mechanism is activated by the magnet 5'K_11 using switch S 2 during the card transports operated in the following circuit: (See Heg. 2) Fuse 6, SKM with parallel Writer coupling relays SKR, S2, RKb, UKd, K 16, 1I S. Furthermore, the writing magnets SM (see Fig. 3) of the desired writing units parallel to the associated meter positions to the relevant lower brushes switched. the Write circuits then run: (see Fig. 3) Fuse 15, write magnets page 91, total clocks SuK, item writing book PS, switching cord according to (see Fig. 4) the counter of the same name Sockets PS of the corresponding counter positions, upper contacts of the addition relays A (up to this point parallel to the counter magnets AM), addition-subtraction sockets (see Fig. 2) UB, K 1, UKK, HS.

When writing negative items, the current flow goes (see Fig. 4) via the upper subtraction relay contacts RB instead of via the upper addition relay contacts RA, in parallel to the subtraction magnets SM.

The above storage and possibly also item writing streams come about in every card sensing machine game. As a result included at the group separation (see. Section C 2) the totals the dividend or. Divisor end values the processed card group and, if applicable, the writing work the list of Individual values.

4. Sums notation. If the final values (sums) of dividend and divisor are to be written down before division, a writing game of the machine following the group separation is initiated by means of switch S3 (total writing in dashed working position, Fig. 2) in the following way by the group separation relay contact GRc: Fuse 6, RXe, coil of the summation write relay RS, contact RSa rest side, S 3, GRc, K 16, HS. Contact RSc switches the writing mechanism coupling magnet SKM on again: Fuse 6, SKM with SKR, RSc, K 16, HS. The contact RSd ensures the transfer of the sum contacts SuK in front of the write magnet Sli (see Fig. 3) and the write contacts SK in front of the addition magnet AM by the magnet SuM: (Fig. 2) Fuse 6, SuM, RSd, K 16, HS . The desired writing work stations are controlled by the brush contacts ZK of the relevant counter stations (i to 10 or 31 to 40, see FIG. 4). This control is initiated by coupling the counters by means of their addition magnets AM at the end of the last card sensing machine game at 348 ° in the following circuit: (Fig. 4) Fuse io or 13, AM i to 10 or 31 to 40, write contacts SK, parallel Switched sum writing sockets SS / SL i to io and 31 to 40, switching cords to sum writing sockets SS i or 4, RSe or h, K i9 (see Fig. 2) point 2, stop contact b, HS. Until the automatic mechanical disengagement at o, the totals of these counter digits are rotated further by the value io, ie back to the respective starting value; the total value remains unchanged. When the sum workplaces pass through o, the sum write pulse corresponding to the output value from K 20 is switched on through the contacts ZK, lower (io-) side, in the following write circuits: (see Fig. 3) fuse 15, write magnets SM, sum contacts SuK , Summation sockets SS, connecting cords according to (see Fig. 4) sockets SS 1 to Mo or 31 to 40 of the same name, meter contacts ZK lower side. K 20, (see Fig. 2) point 2, stop contact h, IIS. 5. Introduction of the division machine games. After the sums have been written, the division is initiated indirectly via an auxiliary relay RS ': (see Fig. 2) Fuse 6, contact RXe, coil RS', RS'a rest side, RSb, K 15, HS. The relay RS 'closes its own holding circuit to HS via its contact RS'd working side, and via its contact RS'b it excites at 29o °, ie shortly before the o-control is switched on by the distributor (see Fig. 15) the start relay RX for the division: (see Fig. 2) fuse 4, coil RX, RXa rest side, RS'b, K 16, HS.

In the event that the totals are no longer written, the start relay RX is switched on immediately after the group separation at 29o ° via the switch S`3 and contact GRc in the drawn rest position in the following way: (see Fig. 2) Fuse 4, coil RX, RXa rest side, S 3, GRc, K 16, HS. The hold circuit for RX runs up to the termination of the division caused by the relay RY in both cases, with or without summation, via: fuse 4, RX, RXa working side, RYb with 'parallel K 9, HS.

The contact RX b (see Fig. 2 bottom right) switches on the division circuits.

It is assumed that the following output values (sums) are contained in the counters at the beginning of the division: in the dividend counter positions 40 ... 31: 0000755173, in the divisor counter positions 10 ... 1: 0000001293.

a) o-control for presetting the column switch. At 297 ° (see Fig. 15), the o-control contacts of the o-positions of the dividend and divisor pre-distributors, as well as the o-control contacts of the dividend and divisor main distributor, the following circuits for the o-relays RI to X of the Dividends (see Fig. 6a) or R i to io of the divisor (see Fig. 7a) prepared: (see Fig. 6a) fuse 8, switch S ia (division); Relay coils RI to X, o-control contacts of the o-points of the dividend pre-distributors VVi to io, of supply contacts of the same to (see Fig its o-control contacts connected in parallel and further via K i; RDc, 9-Rc, RMd, (see Fig. Ii) Point 3, (see Fig. 2) RXb, RYb with parallel contact K 9 back to IIS @. The following parallel circuit branches off behind the switch S ia: (see Fig. 7a) o-relay coils R i to io, o-control contacts of the o-positions of the divisor pre-distributors VV i to io, of feed contacts of the same to (see Fig. 7b) o-pulse contacts of the divisor sum plant SW i 1 »s io, of their feeder contacts to those of the divisor main distributor HV, of its parallel o-control contacts to (see Fig. 6b) K i and further as indicated above. Since, according to the assumption, the dividend sum plant locations 7 to io and the divisor sum plant locations 5 to io are o, i. 1i. their o-pulse contacts with the Lead contacts are connected, so obtained in the above circuits the o-relays R VII to X and R 5 to io current when at 298 ° (see Fig. 2) RXb. RYb, parallel to K 9, HS. About the then form the following stopping points with their kmitacts a Relays VR 16 and 16 'or l' R 4 and @ prepared: R VII to X or R 5 to io after l, # ontakten RV lla to X a or R5a to loa, (s.I'ig. i) l @ z, radio 3, (see Fig. 2) RXb, RY17 parallel 1i 9, HS. About the two chains of the turned-on contacts R VII b to X b and R 5 b to 1o b are also the following circuits for the column counter reiais VR 16 and i6 'or VR 4 mid -l' prepared: (see Fig. ii) Fuse 9, relay coil VR 16, con- takt ! 'R1_ \ V1 rest side, VR 21 VI rest side, * @ 1 b resting side, working side from R V11 b to X b, K 3, point 3, (see Fig. 2) RXb, RYb parallel h 9, f.'S; partly in parallel also: fuse9, IZZclaisspule UR i6 ', R VI h rest side and further Regarding R VII b to X b as above; (see Fig. ii) Fuse 9, coil VR 4, R 4 b rest side, working page from R 5 b to lo h, K 3, point 3 etc. after f: S; Fuse 9, coil UR - [' , R .I b rest side, further via R 5 b to io b as above. In the the circles mentioned above work the column switch relay when closing h 3 at 300 °, after- which all relevant o-relays have responded. The column switch relays VR 16 and VR 4 the current runs for the subsequent one Troll the column dial setting through the difference indicator, the column counter relais VR 16 'and 1'R -4', on the other hand, the circuits for the quotient searcher effective thereafter. Therefore for all four column switch relays the Excitement over K 3 until after your QS work (up to 351 °, see Fig. 15). b) Checking the column switch setting by means of a difference indicator (cf. 134c). At 315 ° (see Fig.15) des Sumiiieiisclireibuiigs- or des of the last card scanning machine game, the submission distributor to the pulse contacts of all divide and divisional university workshops that related resistors (1) _ 1 resistors 9 to o) of the difference indicator (see Fig. 6a to 7b), while the two 13 main distributors handle the supply line contacts of the same total work centers with the fixed bridge resistances or the bridge Connect the relay branches of the differential indicator (see Fig. 10), namely the divisor sums set i to 1o, directly with the would stand W i 'to IV iö, on the other hand the dividend total work stations i to 1 o over the column circuit from multiple contacts of the relay VR ii up to 20 and VR 1 to io with the fixed resistors W i to 1V i o. As in this column circuit in accordance with section a) above, the contacts VR 16 I to VI and hR -1 1 to IV closed are actually the dividend distributors 13 to 6 with the fixed bridge resistances W i to T1'4 and therefore not with the divisor represent i to 4 compared in the following four Wheat- stone from two bridge twigs and'eineni lndil: at @ irzw <° ig. Dividend bridge branch 6: (see Fig. 6a) Fuse 8, switch S ia, DA resistor 7, point of the pre-distributor VV 6, (see Fig. 6b) Impulse contact 7 of the summation station SW 6, point 6 of the main distributor dividend HV, (see Fig. io) contact VR 16 VI, VR 4 IV, resistor W 4, K 4, (see Fig. 6b) contact RDc, 9-Rc, RMd, (see Fig. ii) point 3, ( see Fig. 2) RXb, RYb parallel K 9, HS; Associated divisor bridge branch 4: from switch S i a to (see Fig. 7 a) DA resistor i, position i of VV [, pulse contact i of SW 4, position 4 of divisor HV, (see Fig. io) resistor W 4 , via K 4 as above; The associated indicator circuit 4 (see Fig. 10) between the resistors W 4 and W 4 ' consists of the parallel connection of the I) ifference indicator relay coils R XVII and R XVIII in series, each with a rectifier in opposite polarity.

In the above bridge circuit, the opposite of the corresponding numerical values 7 and i of the highest places, the DA comparison resistances cause the relay R XVII (see section B 4b) to respond. Its contact in the excitation circuit of the differential relay RD (see Fig. I 1) remains without effect because of the open contact K 5. 1) which contain three further bridge circuits accordingly in the dividend bridge branches the Sunimenwerkstellen 5 to 3 and the associated DA resistors 5 and i, in the divisor bridge branches 3 to i with the DA resistors st <inden 2, 9 and 3 as well as in indicator branches 3 to i the DA relay coils R XVI and R XV or R XIV and R XIII or R XII and R XI. Of that work in the indicator circuit 3: R XV; in Circuit 2: R XIV; in circuit i R XII, there in the former the value of the dividend point, in the latter two the divisor places values predominate. The associated relay contacts R XV. XIV. \ II in the RD circle (see Fig. ii) are however due to the to the two highest \ i 'create associated contact of the relay R \ VII by: \ disconnection made ineffective. 1) After that, the column switch setting remains for the two closing operations without l @ orrchtur be: teliell. At 3.I2 ° (see Fig. 15) you can then the llaltekreise for 6'R 1 to 20 Tiber own Contacts are at the contact £ i 21 to i8o ° des following machine game take effect. c) Determination of the highest quotient digit using the quotient finder (see B 2). in the C) tiotientensucherstronikreis already has the colon netischalterreIais VR 16 'the Hutiderter-QS-cons amounts <oo to ioo of the dividend (Fig. 6a, b) with the Q.S'-1, # ontakteti of the [) dividend distributor l'l '(i \ -erllunden, furthermore the Zeliner-QS-Wider- st; indc oo to io init the QA contacts of VV 5 and the l? itier-QS - \% 'iderstands 9 to t with the l '!' 4 contacts. l'Accordingly, takt- \ -on ['R -i' (see Fig. 7 a, b) the Ilunderter-QS- Resist coo to 100 of the divisor to the QA honta @ te the 1) i \ -isor pre-distributor VV 4 and likewise the tens resistances 9o to to an 1l "3 as well as the one resistors 9 to i at VV 2. Therefore, after closing the QS contacts of the preliminary and main distributors at 336 ° of the same total writing or last card sampling cycle via the respective pulse contacts of the corresponding total work stations, the following current flows for the DC version according to Fig. 8a of the quotient finder for the dividend current branches: (see Fig. 6a) fuse 8, switch S za, (see Fig. 8) series-connected upper identical windings of the differential relays D 2 to D 9, (see Fig. 6a) QS resistor 700, contact VR 16 ', QS contact 7 from VV 6, (see Fig. 61>) Impulse contact 7 of the sum factory, Y'Li #' 6. QS contact 6 of the dividend HV; K8, RDc, 9-Rc, RMd, (see Fig. Ii) Point 3, (see Fig. 2) RXb, Rl'b parallel K 9. HS. The following branches are parallel to the above circle: from the upper relay winding D 9 to (see Fig. 6a) QS resistor 5o, contact VR 16 ', (see Fig. 6b) Q.S'-contact 5 from VV 5, Impulse contact 5 from .SW 5, Q.S'-contact 5 desDividenden-Hh further via K 8 as above; from D 9 to (see Fig. 6a) QS resistor 5, contact VR 16 ', QS contact 5 from 1'G "4, (see Fig. 6b) pulse contact 5 from SW 4, OS contact .4 of the Dividenden-HTL further via K 8; also the following divisor branches: from S ia (see Fig. 6a) to (see Fig. 8) in succession switched, lower graduated differential relay winding lungs D 2 to D 9, (see Fig. 7a) QS resistance i oo, contact VR 4, QS contact i from VV 4 (see Fig. 7 b) Impulse contact i from S H '4, QS-Kon- cycle 4 of the divisor HV, (see Fig. 6b) continue via K8 as above; from lower relay winding D 9 (see Fig. 8) according to (see Fig. 7a) QS resistor 2o, contact VR , (see Fig. 7 b) QS contact 2 of W 3, impulse contact 2 of SW 3, QS contact 3 of Divisor-HV, continue through K 8 as above; from lower D 9-Wick- development (see Fig. 8) to (see Fig. 7a) QS re- stand 9, contact VR 4 ', QS contact 9 of VV 2, (see Fig. 7 b) _ Pulse contact 9 of SW 2, QS-Kon- measure 2 of the divisor HV, continue via K B. Because the current is in every QS resistor Numerical value is proportional, corresponds to the current in the series connection of the eight upper differential relay windings of the sum of the values of the three parallel len dividend QS resistors 700, 5o and 5, so 755, the current in the lower differential relay windings, on the other hand, the value of the three parallel I) ivisor-QS-Widerstätide Zoo, 20 and 9, namely 129. The ratio of the two currents. ratio of the three highest digits of the dividend to those of the divisor, i.e. equal to an approximate throw of the quotient to be determined has accordingly the amount 755: 129 = 5.85. As a result, the Difference relays D 6 to D 9 with one of this current ratio exceeding their turns ratio Contacts around. As a result, the product relay x 5) in the following circuit: (see Fig.6a) Fuse 8, (see Fig. 8) PR coil x 5, contact D 5 Rest page, working page from D 6 to D 9, rest page from RDf and 9-Rf, (see Fig. ii) K 21, point 3, (see Fig. 2) RXb, RYb parallel K g, HS. PRx 5 The following holding circle is formed at 342 °: (see Fig. 8) Fuse 8, coil x 5, contact x 5 I, (see Fig. ii) K 17, point 3, continue as above. This relay therefore establishes 5 as the highest quotient digit.

In the alternating current version according to FIG. 8 of the quotient finder, a special alternating current source W of technical frequency (see FIG. 8) and differential elements are used for the actual comparison of the QS resistances. In this case, the circuit for the dividend branches is as follows: (see FIG. 8) AC power source W, fuse 18, switch S ib; Primary windings of the eight transformers T i (with turns ratio i: i), further as with the direct current version (see Fig. 6a to 7b) via QS resistors VV, SW, HV to K 8, further to (see Fig. 8) RDe , 9-Re, RMf, RXe, back to the AC power source W.

The divisor branches that are partially parallel to this run (see Fig. 8) from S ib to the primary windings of the eight transformers T 2 to T 9 (with turn ratios i: 2 to i: 9), further as in the direct current version (see Fig. 6a to 7b ) via QS resistors VV, SW, HV according to K 8, further as above according to RDe etc. The two identical windings of the differential relays D 2 to D 9 are connected to the secondary windings of the two transformer groups with a rectifier cell interposed, which are thus under respond to the same conditions as the relays of the same name for the direct current version and also control the product relays PR (see Fig. 8) in the same way.

At the end of the total writing or last card sensing game, further preparatory controls for the first division machine game that follows take place. The column switch relays VRR and hRN for the multiplication are connected to voltage at 328 ° via K 22 (see Fig. 15): (see Fig. 13) Fuse J4, coil hRN with parallel coil hRR and contact RMb rest side, K 22, ( see Fig. ii) Point 3, (see Fig. 2) RXb, RYb with parallel K g, HS.

At the same time, the subtraction relays RB 31 to 40 for the dividend counter and the addition relays RA 11 to, 2o for the quotient counter are switched on by means of the distribution relays RC i and RC 2: (see Fig. 13) fuse 14, 9-Rb, switch S 6 and coil RC i with parallel S @ and coil RC 2, K 22, (see Fig. Ii) Point 3, (see Fig. 2) RX b, RYb with parallel K 9, HS; partially in parallel with this: (see FIG. 2) fuse 7, (see FIG. 13) coils RB 31 to 40, connected in parallel via switching sockets, switching cord, contact RC i working side, further as above via K 22; furthermore: from fuse 7 to (see Fig. 13) coils RA i i to 20, connected in parallel via switching sockets, switching cord, contact RC 2 working side, further as above via K 22.

6. First division machine game. a) Formation of the right partial product and its subtractive transfer to the dividend counter. At 2 ° of the immediately following first division machine game, ie at 9, the addition magnets AM 31 to 4o of all dividend counters (see Fig. 4) are excited via contacts RB 31 to 40 and K 18 (circuit see section C 3), so these Counter positions engaged.

At 72 °, ie at 5, the subtraction magnets SM 33, 34 and 36 are used to disengage the dividend counter positions 3, 4 and 6 when subtracting the right partial product (quotient 500 times divisor 1293) in the following by the column switch relays VR 16 and VR 4 Prepared current course: (see Fig. 4) Fuse 13, magnet SM 33 or 34 or 36, extinguishing contact ZK 33 or 34 or 36, lower contacts RA 33 or 34 or 36, sockets addition - subtraction 33 or - 34 or 36, switching cords, sockets sub-product 3 or 4 or 6, (see Fig. 12) contacts VR 16 IX or X or XII, contacts VR 4 V or VI or VIII, (see Fig. 12) 7b, 7a) 9-o-contacts i or 2 or 4 of the divisor HV, pulse contacts 3 or 9 or i of the SW positions i or 2 or 4, positions 3 or 9 or i of the hh i or 2 or 4, from their 9-o contacts via (see Fig. 9) lines 3 or 9 or i to contacts hRR III or IX or I (while contacts VRN I to X are open), contacts x 5 R IV or VII or III, impulse line 5, impu Contact 5 of the sum pulse contact SI, (s. Fig. 2) Point 2, stop contact b, HS.

All other dividend counter digits are mechanically disengaged at o.

That means for the dividend places 3, 4 and 6 the addition of the false ger complement to 5, namely a 4, for the other places addition of a 9 (false complement to o); So the following applies to the dividend counter digits 31 to 4o after the tens carry (see section C 3) of the first division game: Digit 4o to 31 0000755173 dividend starting value, (- 00005055oo) right partial product (divisor 1293 times quotient 5oo), 9999494499 spurious complement of the right Partial product, 0000249672 + i carry forward from the 10- digit (40), oooo249673 dividend minus right part product. b) Quotient storage (see B 5e). Simultaneously with the subtraction transfer of the right partial product, at 5 = 75 °, the highest quotient digit determined by the quotient finder, namely the 5 in the hundred digit, is transferred to the quotient counter digits ii to 2o, i.e. to digit 13, through the following circuit: (see Fig. 4) fuse ii, addition magnet AM 13, SK 13, ZÜ contact 13, lower contact RA 13, socket addition-subtraction 13, switching cord according to (see Fig. 14) socket quotient 3, contact VR4 XI, Contact VR 16X111, V RR X, product relay contact x 511, (see Fig. 9) Sum pulse contact S1 5, (see Fig. 2) point 2, stop contact b, HS.

As a result, the quotient counter digits contain the following values: Digits 20 to 11 0000000500 quotient. Immediately after the transfer of the right partial product, at 192 ° of the first division machine game (see Fig. 15), the formation and transfer of the left partial product is prepared by energizing the relay RM: (see Fig. 13) Fuse 14, coil RM, contact VRL X, K 23 (see Fig. 6 b) RDc, 9-Rc, RMd, point 3, (see Fig. 2) -RXb, RYb, parallel K g, HS.

RM remains until the end of the transfer (to o) in the next machine game in the following holding circuit, which is partially parallel to the excitation circuit: (see Fig. 13) from coil RM to contact RMa, K 24, point 3, continue as above. Contact RMb (see Fig. 13) prepares the excitation circuit for the multiplication column switch VRL, which is closed at 327 ° by K 22: (see Fig. 13) Fuse 14, coil VRL, contact VRL I rest side, RMb working side, K 22, point 3, (see Fig. 2) RXb, RYb parallel to K 9, HS.

VRL persists during the transfer of the left partial product via: (see Fig. 13) VRL I working page and (see Fig. 11) K 17, further via point 3, as above.

Through contact RMd, all quotient and column switch controls are switched off until after the transfer of the sub-product on the left. On the other hand, the following controls are maintained: by means of RMc parallel to K 2 (see Fig. 11) the holding circuit for the o-relays (and possibly also for the correction relay VR21 or R rr) to control the column switches, by means of RMe parallel to K 17 (see Fig. 11) the hold circuit for the product relay PRx 5.

Since the left partial product represents the tens of the right partial product (= units of the individual products of the individual divisor places) (see Section II, 5c, 5d) , a position shift by one place to the left is already carried out at the end of the first division machine game by means of the contacts VRLXI to XX (see Fig. 11) initiated. At 327 ° (see Fig. 15, K 22), the column switch relay VR 17 is switched on in place of VR 16 via the o-relay contacts RV II b to X b, which are still folded, namely through contact VRL XVI (complete circuit see section 11I, 4b). During the switchover, the hold circuit for the column switch is interrupted by K 21.

7. Second division machine game. a) Formation and subtractive transfer of the left partial product (cf. B 5 c). At 2 ° of the subsequent second division game, as described in Sections C 6a and C 3, all dividend counter digits are coupled in for the purpose of subtraction. The subtraction transmission circuit for the left partial product (divisor 1293 times quotient 500) runs in comparison to the circuit described in Section C 6a for the right partial product via (see FIG. 12) the contacts VR 17 XI to XIV instead of VR 16 IX to XII and via (see Fig. 9) VRL II or III or IX instead of VRR I or III or IX, furthermore via PR contacts x 5 L VII or IX or XV instead of PRx 5 R III or IV or VII. As a result, the dividend counter digit 35 (5) is disengaged at 4, the digits 34 (4) and 36 (6) at 1, all other digits at o. The result for the entire dividend counter is: Positions 40 to 31 0000249673 dividend minus right part product, (- 0000141000) left partial product (divisor 1293 times quotient 500), + 9999858999 spurious complement of the left one Partial product, ooooro8672 + 1 tens carry over from the to. Place (40), ooooro8673 dividend minus full Product (divisor times quotient 500). After the tens carry over, the dividend counter contains the remainder of the dividend after the first division machine game. Immediately afterwards, two checks are carried out on it for the correctness of the quotient position determined. Both controls are prepared by closing the contact RMd (see Fig. 61>) after switching off the relay RM through K 24 (see Fig. 13).

b) Check the quotient for too high a value by means of an ger control (see B 4.a). In this case, a check for the presence of a negative, thus complementary dividend remainder, d. 1i. a 9 in the tenth dividend sum workstation, necessary. The 9 control circuit therefore runs through except RMd (see Fig. 6b) the contact 9 of the dividend sum workstation SW to; this circuit However, in the present normal case there is a positive dividend remainder, i.e. one o in the tenth position, in the 9-control position the distributor at 259 ° is not comes about and has no effect.

c) Quotient control for too small a value by means of a difference indicator (cf. B 4b). The necessary comparison of the remainder of the dividend with the divisor must be made in the original position assignment that is decisive for the transfer of the right partial product. Therefore, the column switches VR 16 and VR 4 after the column switch holding circuits are interrupted by K 21 (see FIG. 11) and after VRL has been switched off by K 17 (see FIGS. 13, 11) via the up to 288 ' (K 2 ) held o-relay contacts at 228 ° (see Fig. 15, K 3) readjusted. The holding circles for VR 16 and VR 4 above K 21 are maintained until the end of this test.

At 276 ° (see FIG. 15), the upstream and main distributors and also close K4 the same bridge circuits, as with the column counter control already described. However, since in the dividend positions 6 to 3, those with the unchanged Divisor places 4 to i (value 1293) are compared, now the smaller value of the Dividend remainder 1o86 is contained, the following differential indicator relays (see Sect. Fig. 1o) In the indicator circuit 4 due to v @ 7 equality of the highest places (r) no relay: in the indicator circuit 3 (read relay R XVI, as the third divisor 2 greater than the fifth dividend digit o; in the indicator circuit 2 the relay R XIV (divisor 9 greater than dividend 8); in the indicator circuit t (read relay R XI (dividend 6 greater than divisor 3).

Since the contact R XVI (see Fig. 11) all contacts with a lower number switches off, it remains in the excitation circuit for R interrupted by K 7 11 without effect, d. 1i. the determined quotient digit 5 is correct, and the next one Division machine play can run unhindered.

d) "Second o-control for presetting the column switches (cf. C 5a). Since the remainder of the dividend still has the same number of digits as the initial value, at 297 '(see Fig. 15) the o-control contacts give the precedence and main distributor, the same o-relay circuits are established as at the beginning of the division (see section C 5a), whereby the o-relays R VII to X and R 5 to 1o (see Fig. 6a, 7a) respond and communicate via K 2 (see Fig. 11) The column switch relays VR 16 and VR 4 as well as VR 16 'and VR 4' are in turn switched on by their b-contacts and K 3.

e) Second column counter control by means of a differential indicator (cf. C 5b). In order to check the above unchanged column switch presetting, the same bridge and indicator flow runs result in the difference indicator as in the previous quotient check; only now the following circuit for the pre-correction relay R 11 is closed via contact R XVI at 320 ": (see Fig. 11) Fuse 9, rest side of contacts R XXIX to R XVII, R XVI working side, coil R il, K 7, point 3, (see Fig. 2) RNb, RYb parallel K 9, H, S. R 11 forms the holding circuit: Fuse 9, contact R i1 a, coil R ii, R 11 b, K 2, continue via point 3 as above.

After the DA excitation circuits have been switched off by K 4 (see FIG. 15), the correction relay VR 21 is then energized at 326 'via K 22 as follows: (see FIG. 11) Fuse 9, coil VR 21, contact VR 21 NI Rest side, (see Fig. 13) K 22, point 3, (see Fig. 2) RK b, RYb, parallel K 9, HS. VR 21 lies over I% R 21 XI working side parallel to coil R ii in its holding circle (see Fig. Ii). VR 21 switches the column switch with its contact VR 21 VI in the group VR 21 I to X (see Fig. Ii) next lower »Timnier, i.e. VR 15 instead VR 16, one, with UR 21 I V , in group VR 21 I 'to X', on the other hand, the next higher column switch, i.e. VR 5 'instead of I'R.4'. The column switches VR 15 and VR s as well as VR 16 'and VR 3' is therefore the job assignment of the highest 1) i1-isorstell.e to the second highest dividend residual position is the following Division processes bestinfinit. f) Determination of the z \\ - void list quotient- establish with an anti-inflammatory prick (@ -gl.

B. Third Division Machine Game. a) Second Education and subtractive transfer of rights Partial product (see. C 6a). At 2 '(9) of the subsequent at the end of the 1-machine game are in accordance with Section C 6 a, all dividend counting workshops using the addition magnets AM 31 coupled up to 40. For the decoupling of the dividend counting which now contain the amount Tob 673. by means of the alignment niagnete during the transmission In the right partial product (divisor 1293 vial quotient 9o) there are the following circuits, now determined by the column switches VR 15 and VR 4: (see Fig. 4) Fuse 13, magnets SM 32 to 35, extinguishing contacts 1_K 32 to 35, lower contacts RA 32 to 35, sockets addition-subtraction 32 to 35, switching cords, sockets partial product 2 to 5. (see Fig. 12) Contacts VR 15 VII to X, UR 4 V to VIII, (see Fig. 7 b, a ) 9-o-contacts 1 to 4 of the divisor Hl ', pulse contacts 3, c, 2, 1 of the.S@I1'-Stelleii i to 4, positions 3 or 9, 2, 1 of the!'1'i to 4, 9-o contacts of the same (see Fig. 9) lines 3, 9, 2, 1, contacts VRR III, IX, 1I, I (contacts VRX 1 to X are open). Contacts x 9 RV, XI, IV, 11I, contacts 7, 1, 8 and 9 of the Suminenimpulskoutaktes S1, (see Fig. 2) point 2, stop contact 1), HS.

As a result, the following are disengaged: Counter position 35 immediately back to 9, position 34 to 8, position 32 to 7, position 33 to i, all other dividend positions mechanical to o, i.e. it is added: 9 in position 31, 2 in 32, 8 in 33, 1 i11 34, 0 in 35, 9 in 36 to 40. After the tens carryover, the following then applies to the entire divi (latency counter: Positions 40 to 31 ooo0108673 residual dividend after first I) ivisioll (quotient 500), ` (- 000009817o) right partial product (divisor 1293 times quotient 9o), 9999901829 spurious complement of the right Partial product, 0000010502 i carry over from the to. Place (40), 00000 10503 dividend remainder minus right Partial product. b) Second storage of quotients (cf. C 6b). At the beginning of the above-described subtraction transfer of the right partial product, the second highest, i.e. tens quotient digit, is simultaneously transferred additively to the quotient counter, as follows: (see Fig. 4) fuse ii, addition magnet .4: '1T 12, SK 12, ZH contact 12. lower l # .oiltakt RA 12, luchse addition-subtraction 12, switching cord. (see Fig. 14) Socket quotient 2, contact VR .4 X, VR 15 XI, VRR X, I'Rx 9 11, (see Fig. 9) Contact 9 of S1, (see Fig. 2) point 2, stop contact b, HS. The quotient counter then contains: Digit 20 to 1 1 o00o0o050o first quotient digit, -1- oooooooogo second quotient digit, ooooooo59o two-digit quotient. Immediately after the transmission of the right-hand bearing product, that of the left-hand product is prepared by I: regting of Rill, VRL and VRl '(see Fig. 13), switching off the quotient and column counter controls in the second half of this third division machine game (see Fig. 13). Fig. Eil) and maintenance of the hold circuits for the o-relays, R ii and VR 21, PRx 9 (see Fig. I 1) in the same circuits as already described above.

In this case, contact VRL XV also becomes the column switch VR 16 switched on instead of VR 15; VR 4 remains switched on unchanged.

9. Fourth division machine game. a) Second education and subtractive Transfer of the left partial product (cf. C 7a). At 9 everything is engaged Dividend counter digits in a known manner.

The following subtraction circuits exist for disengaging: (see Fig. 4) Fuse 13, S111 33 to 35, LW 33 to 35, RA 33 to 35, sockets. . \ ddition-Sulltraktion 33 to 35: Bushings partial product 3 to 5. (see Fig. 12) VR 16 IX to XI; VR 4 V to VII, (see Fig. 71 ) , a) Divisor HV positionii i to 3, pulse contacts 3 or 9, 2 from SW i to 3, positions 3 or 9, 2 of VV i to 3 , (see Fig. 9) VRL III or IX, 1I; PRx 9 L XIII or XIX, XII; Contacts 2 or 8, 1 of the SI contact (see Fig. 2) transmits 2nd stop contact b, HS.

The following are therefore disengaged: dividend point 34 at 8, steeple 33 at 2, position 35 at i, all other positions mechanically at o, d. H. it is added: 9 in digits 31 and 32, 7 in 33, 1 in 34, 8 in 35, 9 in 36 bis, 4o.

The following then applies to the dividend: Positions 40 to 31 0000010.503 dividend remainder minus right Partial product, (- 0000018200) left partial product (divisor 1293 times quotient, 9o), + 9999981799 spurious complement of the left one Partial product, 9999992302 Dividend remainder minus full permanent product (divisor times Quotient 9o). A complementary, ie negative, value remains as the obviously incorrect dividend remainder. It is then checked for accuracy.

b) Second ger control (see B 4a and C 711). The exam of the tenth Dividend point - the presence of a complementary 9 is prepared by Switching off relay RM via K 24 (see Fig. 13, 15) and consequently closing the Contact RMd (see Fig. 6b).

In the 9 control position of the distributor, the following excitation circuit for the 9 relay exists at 259 ° (see Fig. 15): (see Fig. 6a) fuse 8, S ia, coil 9 relay. 9 control contact of point 9 of VV io, (see Fig. 6b) impulse contact 9 of SW io, 9 control contact of dividend HV point io, K 6, RMd point 3, (see Fig. 2) RXb, RYb parallel K 9, HS. The hold circuit runs: from coil 9-relay (see Fig. 6a), contact 9-Ra, (see Fig. 11) K 17, point 3, further as above. The 9-relay determines that the dividend remainder is too small (negative), and it must therefore correct the latter by adding the product (divisor times i) and the last quotient position by subtracting the value i. This is done by the following measures: Contact 9-Rc (see Fig. 6b) interrupts the excitation circuits for the following two-time difference display, the o-control, the quotient finder and in the next game also for RM and thus VRL. When the quotient finder is carried out according to FIG. 8, 9-Re is also effective. Contact 9-Rf 'energizes the product relay PRx i and switches off the others at the same time: (see Fig. 6a) Fuse 8, (see Fig. 8) Coil PRx 1, 9-Rf working side, (see Fig. Ii) K 21, point 3, (see Fig. 2) RXb, RYb parallel K 9, HS, PRx i is held via contact x 1I, (see Fig. Ii) K i7, point 3, further as above. This prepares the correction of the quotient by the amount i and the remainder of the dividend by the positive product (divisor times i) in the following machine game: Contact 9-Rb (see Fig. 13) takes care of the by switching off RC i and RC 2 Reversal of the quotient or dividend counter to correct from addition to subtraction or vice versa by means of the corresponding Re4ais RB I1 to 2o or RA 31 to 4o, contact 9-Rd (see Fig. Ii) holds, parallel to K 2, the Holding circles for the o-relays and the correction relays R 11, VR 21 for column switch control for the following correction game. As a result, after VRL has been switched off at 300 °, the column switches VR 15 and VR 4 are again energized and held during the correction. In addition, VRR and VRN (see Fig. 13) operate normally.

ok Fifth division machine game. a) Correction of the dividend remainder by adding the product divisor times i. The transmission currents for correcting the dividend counter are: (see Fig. 4) fuse 13, addition magnet AM 32 to 35, SK 32 to 35, Zü contacts 32 to 35, lower contacts RA 32 to 35, sockets addition-subtraction 32 to 35 , Sockets sub-product 2 to 5, (see Fig. 12) contacts VR 15 VII to X, VR 4 V to VIII, (see Fig. 7 a, b) divisor HV positions i to 4, pulse contacts 3 resp. 9, 2, 1 of the SW i to 4, positions 3 or 9, 2, 1 of the VV i to 4 (see Fig. 9) Contacts VRR III or IX, 1I, I; PRx i RV or XI, IV, III; Sum pulse contacts .S1 3 or 9, 2, 1, (see Fig. 2) point 2, stop contact b, HS. These cause the addition of the divisor value 12930 as follows: Positions 40 to 31 9999992302 second remainder of the dividend, + 0000012930 (fake partial) product (Divisor 1293 times i), 0000005232 + i carry forward from the 10th position (40), 0000005233 corrected second dividend rest. b) Correction of the last quotient digit by subtracting the value i. Simultaneously with the above transfer in the dividend counter, the following subtraction transfer takes place in the quotient counter, whose addition magnets AM ii to 2o (see Fig. 4) are activated immediately at 9 in a known manner via K i8: (see Fig. 4) fuse ii , SM 12, LK 12, RA 12, socket addition-subtraction 12, (see Fig. 14) socket quotient 2, VR 4 X, VR 15 XI, VRR X; PRx i II, (see Fig. 9) Impulse contact i of S1, (see Fig. 2) point 2, stop contact b, HS. Accordingly, the decoupling of position 12 is effected at i, the other positions mechanically at o, i.e. addition of 8 and 9 as follows: Digit 2o to ii 0000000590 two-digit quotient, (-ooooooooio) correction -i, + 9999999989 fake complement of Correction - i, 0000000579 i carry forward from the ok Place (20), ooooooo58o corrected two-digit Quotient. c) Third party inspection (see C 9 b). After the correction of the remainder of the dividend described above, the tenth dividend position no longer contains a 9, so that the 9 relay remains de-energized and has no effect.

d) Second quotient check using a difference indicator (cf. C 7 c). For the subsequent comparison of the corrected remainder of the dividend with the divisor, the column switches VR 15 and VR 4 are switched on again via the o and correction relay contacts at 228 ', which have remained unchanged until after its termination (288 °), through K 3 (see Fig. 15) ( see section C 7 e) and held via K 21. As a result, analogous to the difference display circuits of sections C 5 b and C 6 c, the dividend digits 5 to 2 are compared with the corrected value 0523 (see section C io), with the divisors 4 to i with the unchanged value 1293 According to FIG. 10, since the fourth divisor position i exceeds the fifth dividend position o, the difference indicator relay R XVIII responds. Its contact in the exciter circuit for R ii interrupted by K 7 (see FIG. Ii), however, has no effect, ie the corrected quotient and dividend remainder are correct, and the next division process can follow.

. e) Third o-control (cf. C 7 d). Since the corrected dividend remainder after section C io, as the divisor only has four digits, closes K i to section C 5 a analog circuits for the o-relays R V to X and R 5 to io with corresponding holding circles over K 2. According to Fig. i i switch the b contacts the o-relay corresponds to the column switch relays VR 14 and VR 14 as well as VR 4 and VR 4 '.

f) Third column counter control (cf. C 7 e). For value comparison between corrected dividend remainder and divisor are via the contacts VR 14 and VR 4 of FIG. 10 the divisor places q to t (value r293), the dividend places 4 to 1 (value 5233) assigned. In the relevant indicator circuit 4 speaks then that belonging to the larger dividend digit 5 (compared to i of the divisor) Difference indicator relay R XVII on. His contact in the open circuit at K 5 the relay RD (see Fig. i i) has no effect, d. H. the ones that have just been switched on Column switches VR 14 and VR 4 or VR 14 and VR 4 remain in function.

g) Third determination of the quotient position. Analogous to the circuits of the two previous quotient determinations (see Section C 5 c), the column switches VR 14 and VR 4 place the three highest totaling stations of the dividend 523 and the divisor 129 in the two QS current branches and produce the corresponding current values in them. The current ratio then has the amount 523: 129 = 4.06. Assumed, as a result of z. B. faulty contact resistance or imprecise turns ratio, if not only the differential relays D 5 to 9 but also the relay D 4 respond (see Fig. 8), the product relay PRx 3 is excited and held, i.e. 3 as the third quotient digit determined.

The further activation of the Relays VRR, VRN, RC i and 2, RA i i to 20 and RB 31 to 40 take place in the already described Way (see Sections C 6 a and C 8 a).

i i. Sixth division machine game. a) Third education and subtractive Transfer of the right partial product (cf. C 8 a). The subtraction transfer will again as introduced in section C 6 a and C 8 a by coupling in all dividend points via A11131 to 40.

According to the circuits described there, the right partial product (divisor 1293 times quotient 3) is subtracted from the corrected dividend remainder 5233 using the column switches VR 14 and VR 4 as follows: Positions 40 to 31 0000005233 corrected second dividend rest, (- 0000003679) right partial product (divisor 1293 times quotient 3), + 9999996320 spurious complement of the right Partial product, 0000001553 + i carry forward from the 10th position (40), 0000001554 corrected second dividend rest minus right partial product. b) Third storage of quotients (cf. C 8b). The addition transfer of the value 3 determined according to section C iof to the first quotient counter position (ii) takes place in a current curve analogous to section C8b via VR 14 and VR4 contacts as follows: Positions 20 to 11 0000000580 two-digit quotient, + 0000000003 third quotient digit; 0000000583 three-digit quotient. The next partial product transfer is prepared according to Sections C 9 a and C 7 a by energizing the relays RM, VRL, VRN 'and VR 15 instead of VR 14, switching off the previous quotient and column switch controls and maintaining the hold circuits for the o relays, R ii , VR 21 and PRx 3.

12. Seventh division machine game. a) Third formation and subtractive transfer of the left partial product (cf. C 9a). As a result, analogous to the earlier transfers mentioned, the left partial product (divisor 1293 times quotient 3) is subtracted from 'the dividend places 32 to 35 (see section C iög): Positions 40 to 31 ooooooi554 corrected second dividend rest minus right partial product, (- 0000000200) left partial product (divisor 1293 times quotient 3), - 9999999799 spurious complement of the left one Partial product, 0000001353 + i carry forward from the ok Place (40), 0000001354 third remainder of the dividend. b) Fourth ger control (cf. C 91) and foc).

The subsequent check of the third remainder of the dividend for complementary ones 9 is in the tenth position in the circuit according to Section C9b, as in the case of C ioc, negative. This is followed by c) Third quotient control by means of a difference indicator (cf. C 7 c and C iod).

The comparison of the third remainder of the dividend 1354, which is too large, with the divisor 1293 is prepared by reactivating the column switches VR 14 and VR 4 as in section C iod. Accordingly, in the indicator circuit 4 (see Fig. 10) the fourth dividend and divisor positions with the same values i are compared with one another, in the next decisive indicator circuit 3 the third dividend position 3 is compared with the third divisor position 2. In circuit 4, therefore, works No differential indicator relay, but relay R XV in circuit 3. Its contact closes at 282 ° (see Fig. 15, K 5) the following excitation circuit for the relay RD: (see Fig. Ii) Fuse 9, rest side from R XXIX to R XVI, R XV working side, coil RD, K 5, point 3, (see Fig. 2) RXb, RYb, parallel K 9, HS. The hold circuit is as follows: (see Fig. Ii) Fuse 9, RDa, coil RD, RDb, K 17, point 3, continue as above. The relay RD registers an excessively large dividend remainder and must therefore correct it by subtracting the product (divisor times i), as well as correcting the last ouotient position by adding the value tra:; it! ver <tnlasseti with the help of the following -: \ Iass- riahn: en: cost cycle RDc (see Fig. 61>) switches: t die Excitation circuits for the subsequent o-control, Difference display and quotientl> estimmueg, as well as for R_Il and flRI, im nahcli @ t; ii `: lascliinensl) iel, ab.

Eighth division machine game. a) correct ture des I) ivide: idenrestes by subtracting the Product divisor times i. The correction over- transfer takes place after all dividend a he at 9 according to the normal count Partial product transfers subtractively as follows: (See Fig. 4) Fuse 13, Subtraktionsinagn ° te Sll 31 to 34, LK 31 to 34, R_9 31 to 34, sockets Addition-subtraction 31 to 34, sockets part product i to 4, (see Fig. 12) contacts VR i4V to VIII, VR 4 V to VIII, (see hig. 71), a) i to 4, pulse contacts 3 or 9, 2, 1 of SW t to 4, positions 3 or 9, 2, 1 of VV 1 to 4, (see Fig. 9) Contacts hRR III and I \. 1I, I; PRx 1 V or XI, IV, 11I, sum pulse con- clocks SI 3 or 9, 2, 1, (see Fig. 2) point 2, stop contact b, HS. This subtraction of the divisor 1293 of the remaining dividend 1354 has the result: Positions 40 to 31 0000001354 third remainder of the dividend, (- 0000001293) right (partial) product (Divisor 1293 times i), 9999998706 spurious complement of the product (divisor times t), oooooooo6o t carry over from the 10- digit (40), oooooooo61 corrected third dividend rest. b) Correction of the last quotation digit by adding the value t. Simultaneously with the correction of the dividend remainder, the quotient takes place like a normal storage al_s addition transfer, namely the value 1 in the first ouotient counter (ii), as follows: (see Fig. 4) fuse ii, AM ii, SK ii , ZÜ contact ii, RA i 1, socket addition-subtraction ti, (see Fig. 14) socket quotient i, contact VR4 IX, VR 14 IX, VRR X, PRx 1 1I, (see Fig. 9) pulse contact 1 of S1, (see Fig. 2) point 2, stop contact b, HS The 1 @ _rgelmis is (see. \ L @ sdinitt C! 11)): place 20 to S t 1 0000000 <53 three-digit () uoticnt. 00000 <) 00o htirmktur - 7. 00000003e corrected three-digit () uotient.

The contact RYb (see Fig. 2) prepares the disconnection of all division circuits including the start relay RX which takes place at 333 ° by K 9. The contact RYc (see Fig. 2) switches: the group separation relay GR . The contact RYd (see FIG. 2) maintains the excitation of the relay UGR and thus the disconnection of GR during the subsequent writing of the quotient via the switch S 4 d. The contact RYe (see Fig: 2) continues to interrupt the card transport nritteli of the KKM while the quotient is being written (switch S 4 c is open). The contact RYf (see Fig. 2) starts the writing mechanism with the aid of the magnet SKM, and the contact RYg (see Fig. 4) switches on the writing mechanism control through the quotient counter. The contact RYli (s. Fig. 2) causes about S, 4 b by means of the magnet SuM switching the sum contacts SuK (s. F'ig. 3) in the feed lines of the writing magnets S.VI, as well as the write contacts SK before the counter magnets AT THE. The contact RYi (see FIG. 2) finally controls via the switch S 5 with the help of the clearing magnet LM the switching of the clearing contacts LK (see FIG. 4) and thus the counter clearing.

1.1. Quotient writing and counter deletion. The result of the division, quotient and dividend remainder is written down during the following machine game using the writing mechanism. The writing magnets SM (see FIG. 3) are controlled by the quotient and dividend counter, namely by the brush contacts ZK of the relevant counter positions ii irises 20 and 31 to 40, via their sum; mensehreibungsbuchungsbuchsen SS. This control is initiated through common coupling of all counters (including the divisor counter) at 348 ° of the last division machine game (see Fig. 15, K i9) in the following circuit: (see Fig. 4) fuses io, il, 13; Addition magnets AM i to 20, 31 to 40; Write contacts SK i to 20, 31 to 4o; sockets SS-SL i to io or ii to 20, 31 to 40 connected in parallel, quotient writing sockets QS i or z, 4; RYg or k, in; K r9, (see Fig. 2) point 2, stop contact b, HS When the counter digits pass through o, their contacts ZK (lower sides) lay tension on the one hand via the sockets SS to the writing magnets SM in the same circuits as in the sums according to section C 4, on the other hand via the cleared contacts LK to the subtraction magnets SM, which then disengage the counter positions at o, ie delete them.

The extinguishing circuits then run as follows: (see Fig. 4) fuses io, 1 1, 13; SM 1 to 20, 31 to 40; LK i to 20, 31 to 40; lower pages from ZK i to 20, 31 to 40, K 2o, (see Fig. 2) point 2, stop contact b, HS.

As a result, the quotient is 584 (see Section C 13 b) and the remainder of the dividend 61 (Section C 13 a) in the writing unit for printing and at the same time all Counters are set to o, which are used to record new values, the punch cards to be ready.

After switching off RY by K 12 at 272 °, contact RYe the card head coupling magnet KKM is switched on again and with it the first punch card sensing machine game the next division initiated.
