Description

The invention relates to a device for the automatic transmission of dialing pulses in telephone or teleprinter systems with exchangeable Information carriers for complete call numbers with repeatedly adjustable coding pins, their relative position to a scanning element of a certain to be emitted current impulse sequence corresponds in a cross field, are equipped.

Such a device is known from British patent specification 1,080,773. There the coding pins are designed as connecting pins that are shown in Crossing points of the cross field can be optionally plugged in. This creates the complete call number to be produced in each case. The electric The connection between the contact pin and the cross field is made there using a rotary switch. However, this is done Requires a relatively large amount of space, and incorrect switching is also possible, provided that it is not for an accurate one Synchronicity of the rotary switch is ensured.

U.S. Patent 3,129,294 is one Similar device has become known in which possibly different length coding pins in a Card can be inserted. Fan-shaped, rotatably mounted lever elements, their respective angular position, are placed on the front edges of these pins corresponds to the respective coded digit of the coding pin concerned.

Cassette bottom horizontal strip conductors formed scanning field and cassette cover form a housing that produces a contact memory whose: outputs to the inserted pins surrounds on all sides, so that one equipped with electronic switching means these are guided over the teeth in their set evaluation device. 30 position are anchored. If you want to set a pin in a different position, the cassette cover must be removed from the cross field via the contact element. If the cassette cover is again communicated directly that it has been pushed on with the evaluation device, the position is immovably fixed, connected. This ensures that the cassette lid can be pushed over the cassette floor and works against impacts in a sliding device. Because the evaluation device This allows easy changing of the position of the device is equipped with electronic switching means, pins. So that the contact slide does not have a lot of space after being removed, it works quickly and also takes a certain cassette back into its position insensitive.

They have several pins, the position of which can be adjusted relative to the cash register slide at the same time as a guide for the set housing. The user of the device placed cassettes on him.

(F »E-! 4) Gate G 9. On the negative edge of the ninth clock

For scanning, the programmed pin cassette is output 9 from DC3 to L. This means that the cassette is inserted into the cassette switch 51, see 65 at both inputs of G 9 L level, and via G19 circuit diagram. The individual pins move thereby can be triggered on MFI via its input A 1 to A 18 Al contact bars contact slide, the. MFl determines the time _s = 38ms, which can be set with Podie according to the respective tentiometer P3 from the cassette.

With the positive edge of the pulse at the output Q of MFl, the flip flop FF 4 is immediately reset via G 27 and the clock generator is blocked again. After a further 38 ins, the flip-flop FF 3 is reset again with the negative edge of this pulse via the gates G 25 and 5 G 26 and the pause monofiip-flop MP 2 is triggered via G25. The nsß relay Rs 2 thus drops out again, and the next pause time begins (FIG. 13).

With the negative pulse at the output ~ Q of io MFl, the counting value ZD 3 is reset to zero via the gate G 2 and the flip flop FF 2 is reset (if this was set by a number 0). In addition, the impulse from QiMF \ is counted back into the number decade ZD 1 and now sets output 2 of the decoder DC 1 to L. The second cassette pin or contact bar A 2 is thus selected and the corresponding process is repeated.

The flip-flop FF 2 is used in the event that a cassette pin is queried for the number zero, that is, clock pulses are required. At the 10th clock pulse, the output ~ Q of the flip-flop FF 2 is set to L by ZD 3.

The contact rails A 1 to A 9 or the cassette pins 1 to 9 are selected with ZDl and DCl, the contact rails A 10 to A 18 or the cassette pins 10 to 18 with ZO 2 and DC 2. The transition from counting decade ZDl on ZD2 is accomplished as follows: If the contact bar / 4 9 is selected, the L level at output 9 of DC 1 releases the counting decadc ZD 2, which has been in the zero position, via its input R ₀₁ , so that now the The next and at the same time 10th pulse from QIMFl is counted into both Zälildekaden [ZD 1 and ZD 2), ZD 1 goes back to zero with DCl and output 1 from DC2 to L, i.e. contact bar A 10 is selected. At the same time, the flip-flop FFl was prepared via G 24 in such a way that it was switched over by the 10th pulse from QIMFl. The flip-flop FFl now blocks the counting decade ZDl via gate G 25 and its input R ₀₂ for all further counting pulses after this 10th pulse and enables further counting pulses for the "counting decade ZD 2" through an L level at its input R ₀₂ .

Device or after a power failure ensures that that an extinguishing process is triggered and the electronics go into rest position.

During the deletion process itself, the output of gate G 29 (briefly) goes from H to L. With this L signal on the extinguishing line triggers the following functions:

4.2 Deletion process

After querying the last cassette pin at position Λ18, the counting decade ZD 2 is also reset to zero by the subsequent counting pulse from QJMF 1. The negative pulse edge occurring at output D of ZD 2 reaches an input of gate G 28 via capacitor C9 and initiates the erasing process.

If fewer than 18 pens are required for a phone number, the L level of the control command B = (end of the number) at another input of G 28 triggers the erasure after querying the last digit.

a) The gates G33 and G34 are reset. (These gates are called RÄ-Fhpnop switched.)

b) With the Η level now at the output of G 34, a possibly currently running pause is greatly shortened via G38 and the two transistors Ts6 and TsI and the start button is blocked immediately after this shortened pause time has elapsed via G 30.

c) The lamp LaI is extinguished again via the reset gate G 33.

d) With the L level at the output of G 34, the two flip-flops are activated via G 39, G26 and G27 FF3 and FF4 reset and in this state held. It thus becomes the influence a pause that is still running or a dialing process that is currently running is canceled. In addition, short-term relay excitations when the power is switched on or prevented after a power failure. This lock can only be canceled by pressing the start button will.

e) The counting decades ZD I and ZD 2 are set to zero and flip-flop FFl is reset.

f) Via the gates G 21 and G 22, the counting decade ZD 3 is set to zero and the flip-flop is reset.

The electronics are now in the rest position again, and another query can be made via the Start button are triggered.

If the deletion process is triggered by the stop button, Then the Gl / -contact (fork breaker conact), which is activated at the same time, via which an nsi line is routed, the subscriber loop briefly interrupted, which enables a new dialing without the handset having to hang up the phone beforehand.

A control command B on contact rail B13 occurs when a pin in the cassette is queried for R = winch set. The deletion process can also be started via a third entrance of the gate with the stop key valley

Left input of the gate, G28 is (R43 / C10), which is activated when the 4.3. Intermediate stop A control command Z = intermediate stop to interrupt the dialing process after the preselection number, caused by an L-Pegcl on the contact rail 82, occurs at the beginning of a pause time. It shortens the pause time via gate G38 and transistors Ts6 and TsI and, after this shortened pause time has ended, it reaches G 33 and G34 as a negative reset pulse via G 3 and G 36. The start button is released again via G30, and the two flip-flops FF3 and FF 4 are held in the reset state via G 34, G 39, G 26 and G 27 (see deletion process point d).

The turning process is now stopped. Through the second process of G37, Z holds the lamp Lei switched on Pressing the start button continues the dialing process. .
