The invention relates to the design of the shift register counter according to the main patent application as a special counter, its double flip-flopps with a self-reset pre-control are provided. In the electronic counters according to the invention (up counter, down counter ”and forward -Reverse counter) each decade also consists of 4- • count double flip-flopps and a reversing double flip flop.

The electronic up counter type A, or a decade of this counter, is shown in FIG. The electronic Rücicwarus counter type a, or a decade of this counter is ~ shown in FIG. The electronic up / down counter Type A or a Dexade of this voter is in Figure 3 shown ;. The electronic forward / reverse counter Type B or a decade of this counter is shown in FIG. A deicade of the electronic up counter Type C is shown in FIG. 5 and a decade of the electronic up / down counter Type C is shown in FIG. 6.

One decade of the electronic up-counter type A (FIG. 1), including the reversing double flip-flop, consists of 5 transfer flip-flopps (master flip-flopps) 1 to ρ and 5 memory flip-flopps (slave flip-flopps) -Flopps) 11. to I5. Of these, flip-flops 5 and 15 are the original tax double flip-flop. In other parts of this decade consists of 10 flip-flop control AND circuits 16 and 17 and the AND circuit 13 and the display circuit 19 »consisting of the ^T Jnd circuits 21 to 30 and the negative circuit 3I and the decade carry Uhd circuit 32. The display outputs B are identified with the associated numerical values (digits 0 to 9). The number pulse input has the designation Z and the desaden-transfer output has the designation U. The total reset line has the designation S and its de.caden branch the designation; c. COPY

A decade of the electronic backward counter Type A (fig 2), consists of the same parts as the decade of the electronic Up counter type A (Figure 1) and is additional provided with an actuating circuit 20. Before hiring of the decades to their decimal digits, the entire counter (all decades) must be reset to 0 (zero).

A decade of the electronic up / down counter type A (Figure 3), including reversing double flip-flop, also consists of 5 transfer flip-flopps (master flip-flopps) 1 to 5 and 5 memory flip-flopps ( Slave flip ITlopps) 11 to 15 · Of these, flip flopps 5 and 15 are also the reversing double flip flop. In other parts of this decade consists of 4 flip-flop input circuits 4-1 to 44, consisting of 3 AND circuits and an OR circuit, and also of a flip-flopp input circuit 45, consisting of 4 and- Circuits and 2 OR circuits. The remaining flip-flop input circuits have the numbers 51 to 55. In other parts, this decade consists of the AND circuit 18 and the display circuit 19, consisting of the AND circuits 21 to 30. This consists of other parts Decade from the AND circuits 56 and 57 and the negate circuit 53 and the decade carry circuit 60, consisting of the AND circuits 61 and 62 and the OR circuit 63 and the AND circuit 64. The display outputs B are marked with the associated numerical values (digits 0 to 9). The counting pulse signal also has the designation Z and the decade output the designation U. The overall reset line has the designation S and its decade branch the designation t. The setting for counting up is made by applying Η-potential to the control line V, whereby the control line R has a potential of L via a negating circuit The already mentioned negation circuit has H potential. When counting up, the AND circuit 57 and the decades carry are pre-activated via the AND combinations 61 and 64. With reverse counting, the AND circuit is 56 and the decades carry via the ampersand "necessary 62" and 64, "copy

The mode of operation of the electronic up counter type A consisting of a number of decades according to figure 1 results as follows: All decades are reset by charging line S with a minus current pulse. After this total backlash, all flip-flopps are in their right-hand position (Η-potential at the right-hand exit). Then the first counting pulse follows via input Z. With this first counting pulse, the flip-flopps 1 and 11 flip one after the other into their link position, because when the count is 0 (zero) the Ühd circuit 18 has Η potential at its output and because the left-hand input circuit of the flip-flopp 1 is νor-driven. With this first counting pulse, the flip-flopps 5 and 15 also switch to their left position one after the other, because the AND circuit 30 has Η potential at its output and thus the input circuit on the left side of the flip-flop 5 is pre-controlled is. This means that the line c has Η potential and thus the Uni circuit 21 at both inputs Η potential and the output of this Uhd circuit shows the number 1 with its Η potential. This means that the left-hand input circuit of flip-flopp 2 is precontrolled and the right-hand input circuit of flip-flopp 1 is preceded, so that with the second counting pulse, the flip-flopps 2 and 12 are switched to their left-hand side one after the other. Tilt position and flip-flopps 1 and 11 one after the other to their right position. The AND circuit 22 thus has Η potential at both inputs and thus displays the number 2. The left-side input circuit of flip-flopp 3 and the right-side input circuit of flip-flopp 2 are thus pre-activated, so that with the third counting pulse, flip-flops 3 and 13 turn to their left position one after the other and the flip -Tilt flops 2 and 12 one after the other into their right-hand position. The undo circuit 23 thus has Η potential at both inputs and thus displays the number 3. This means that the input circuit on the Linux side of flip-flopp 4 and the input circuit on the right side of flip-flopp 3 are pre-controlled, so that the flip-flops m and 14 toggle one after the other to their left position with the fourth counting pulse Flip-flopps 3 and 13 one after the other into their right position. This means that the AND circuit 24 has H-potential at both inputs and shows

thus the number 4. This means that only the right-hand input S-circuit of flip-flop 4 is pre-activated, which means that the flip-flops 4 and 14 switch to their right position one after the other on the fifth counting pulse. The AND circuit 18 thus has Η potential at its output and thus the AND circuit 25 has H potential at both inputs and thus shows; number 5. This means that the left-hand input circuit of Flipp-ϊΐορρ 1 is again pre-activated, so that the flip-flopps 1 and 11 flip one after the other into their left position again at the sixth number pulse. In the case of this sixth counting pulse, the right-hand input circuit of flip-flop 5 is also pre-activated, as a result of which flip-flops 5 and 15 also tilt one after the other into their right-hand position. The AND circuits 26 to 30 are thus pre-activated in the display circuit and the AND circuit 26 has Η potential at both inputs and shows; thus the number 6. The linxs-side input circuit of ^ lipp-flopp 2 and the right-side input circuit tiiL.g of flip-flopp 1 are again pre-controlled, whereby the seventh counting pulse causes the flip-flopps 2 and 12 to be in their 'Flip the Lindes position and flip the flip-flopps 1 and 11 one after the other into their right position. The AND circuit 27 thus has H potential at both inputs and thus displays the number 7 . With the eighth count, the flip-flopps 3 and 13 tilt one after the other to their left position and the flip-flopps 2 and 12 one after the other to their right position and the AND circuit 28 displays the number 8. At the ninth counting pulse, according to this principle, the flip-flopps 4 and 14 one after the other to their left position and the flip-flopps 3 and 13 one after the other to their right position and the AND circuit 29 displays the number 9. This means that the De.-caden-transfer-AND-circuit 32 is pre-activated and also the flip-flop 4 is on the right-hand side, whereby a carry-over pulse is sent to the next decade at the tenth dialing pulse from the output of the AND-circuit 32 and the Flip-flopps 4 and 14 one after the other into their right position. The AND circuit 18 thus again has Η potential at its output and thus the AND circuit 30 has Η potential at both inputs and thus displays the number O. This means that the count is the next higher

Decade increased by the number 1 and the meter reading of the present Decade decreased from 9 to O (zero) and starts with the next cycle of this decade with the next count pulse.

In the case of the type O up-counter, one decade of which is shown in FIG. 5, the memory flip-plopps 11 to 11 are only activated on one side. The associated detail F is shown in component symbols in FIG. In this electronic counter, all AND circuits that have only 2 inputs ■ consist of a transistor. The circuits 4-3 are special flip-flop input circuits with which the relevant flip-flop inputs Η-potential and L-potential are controlled.

In the case of the up / down counter type C, of which one decade As shown in Figure 6, the memory flip-flopps 11 to 15 only controlled on one side. The associated Detail F is shown in component symbols in FIG. With this electronic meter, too, all Ühd circuits exist, which only have 2 inputs, from one transistor. The circuits 74- are special flip-flop input circuits, with to which the relevant flip-flop inputs Η-potential · - · and L-potential controlled. In the embodiment 2 of this electronic counter, the memory flip-flopps 15 controlled via both inputs, as shown in FIG Decade.

In Figures 7 and 8, the flip-flopps 2 and 12 (detail F) shown in component symbols, as well as the other parts. The operating current supply lines (operating voltage supply lines) have the designation m and the NuIl- ^ eitungen die Designation n. The other parts and lines have the same designations and numbers as in Figures 5 and c. If so with all AND-circuit transistors in the base line a resistor is required, all relevant transistors in the base line have a resistor.
