Description

Electrically non-contact driven time-keeping device The present Patent application has an electrically non-contact driven time-keeping device to the object, which is a mechanical oscillator, e.g. a regulator assembly in the case of an electric clock or a time standard, etc., with one in relative motion has inductively applied control coil to a permanent magnet, via a semiconductor amplifier circuit, in particular a transistor circuit, the energization of a drive coil perceived, whereby the permanent magnet system, which is connected to the oscillator, electrodynamically applied and semit the relative movement between this and the steering column is upset.

Electrically non-contact driven time-keeping devices have because of Their reliability and operational safety quickly became popular with buyers found for electrical clocks and thus gained considerable importance on the market.

This reliability relies in particular on the fact that the contactless Control of the oscillator used earlier, very sensitive and prone to failure Contacts are superfluous and thus reliable clockworks can be built whose gear folder, for example the unrest, driven directly and thus a very simple one Structure of the clockwork system allows, which in turn increases the price for series devices favored0 The elimination of the contact control of the mechanical effecting the time control Schwingers and the use of contactless control instead of the previously used one Contacts, enables long-term, precise operation of electrical clocks, and it is therefore the purpose of the present.

Invention to reduce power consumption in electronic clocks and in spite of this reduced power consumption an absolute start @ safety both when applying the supply voltage as well as during operation of the clockwork. At the same time, by positively influencing the impulses, the gait behavior is sold the clockwork or timepiece can be improved.

There are already a number of electrically non-contact driven time-keeping Devices with a mechanical oscillator with a relative movement to a permanent magnet system located inductively charged control coil became known, which is a semiconductor circuit, in particular a transistor circuit acts or triggers and thus via the The transistor causes a drive coil to be energized, and thus in turn the magnet system of the mechanical oscillator retroactively applied electrodynamically, whereby the Relative movement between the magnet system and the control coil is maintained, However, these known clock systems have various disadvantages. These lie in the fact that they do not start by themselves or only under certain conditions Conditions have a self-start, in addition, these are known Arrangements by one in relation to the period time of the mechanical oscillator long pulse duration and thus a correspondingly unfavorable degree of efficiency.

Efforts have become known By appropriate design or by appropriate choice of the dimensions of the control coil and the permanent magnet system in relation to the oscillation amplitude of the system, the relative application of the control coil by the permanent magnet system is limited in time so that the duration of the effective pulse is shortened and thus the efficiency is favored, however, these arrangements have the disadvantage that they are strongly dependent on the amplitude and do not allow the mechanical oscillator to start automatically without further measures, which of course in turn increases the power consumption.

In this context it is a semiconductor circuit for an electrical Clock with an inductive movement that is in relative motion to a permanent magnet system acted upon control coil became known, in which the control coil is a capacitor is connected in series and the capacitor alone, or both components together> are bridged by a resistor 0 This branch of the circuit is located now on the one hand at the base of the transistor, on the other hand at the one with the emitter of the transistor not connected pole of the supply current source.

When the supply voltage is applied, the capacitor suddenly becomes charged and thus the base of the transistor is suddenly energized, which in turn the drive coil experiences an impact-like loading. With appropriate dimensioning the circuit can thus start up the gear folder of an electric clock will. After the aisle folder has started, it is controlled inductively via the Control coil, whereby the charge of the capacitor counteracts the control voltage, in such a way that the control voltage is only effective in its extreme tip, By the capacitor, or the capacitor and the control coil connected in parallel Resistance, the capacitor is continuously discharged, so that when appropriate Dimensioning of the circuit a regulation of the amplitude is possible.

It is possible with the help of this circuit to start a rhebliohen to allow higher power consumption, which then by the control effect of the circuit after reaching the full amplitude duroh the aisle folder to a considerably lower level Value is reduced.

The disadvantage of this circuit arrangement, however, is that while it is Apply the supply voltage to the gear folder when it occurs during normal operation Disturbances or braking of the aisle organizer, especially with heavy commuting or Unrest, a safe start is not always guaranteed.

It is also a control circuit for a mechanical oscillator became known, which works using an astable multivibrator, The multivibrator circuit is dimensioned in such a way that it is permanently independent drive pulses generated by the movement of the mechanical oscillator, of which the transducer can be started from the rest position, the transducer has a certain If the minimum amplitude is reached, the astable multivibrator is synchronized retrospectively, so that this then works in the rhythm of the oscillator frequency.

In this circuit arrangement, however, it is disadvantageous that this has to have a common control and drive coil, which is responsible for the dimensioning conditions considerable requirements arise, so it is for example for the assembly of a such a circuit is necessary to narrow the tele-tolerances of the components in the catalog, which of course make them more expensive. Plus, it's cramped despite Component tele-tolerances eft not possible, a safe operation over a sufficient to ensure a large spamming area.

In addition, it is a disadvantage of this circuit connection that in that the frequency of the astable multivibrater is smaller than that at startup Frequens of the oscillator must be chosen, there are differences in the phase positions and therefore only a delayed start-up of the mechanical oscillator is possible will, there. the synchronization of the multivibrator by the mechanical one The oscillator only becomes effective at an increased amplitude0 It is also an electrical one Clock became known in which the relative movement to a permanent magnet system located, inductively acted upon control coil with the drive coil inductively coupled is, so that a so-called relaxation oscillator by the transistor circuit is formed., which by appropriate dimensioning and steaming in the rhythm of the vibrations the mechanical vibrator generates pulse trains which lead to the start-up of the oscillation, with the circuit as an amplifier circuit as the amplitude increases works and caused the final drive of the oscillator This arrangement has however, the disadvantage that it is temperature sensitive and the start-up conditions cannot always be achieved consistently.

In addition, the power consumption is not negligible the invention on which the object is based, while avoiding the aforementioned Disadvantages of a contactlessly driven time-keeping device, especially an electrical one To create clock, which in contrast to the aforementioned facilities by low power consumption, good gait behavior and, in particular, a safe one Start-up of the oscillator distinguishes itself.

According to the invention, this object is achieved in that the in in a manner known per se via a capacity acted upon by the Ste @@@@ pule, the drive coil energizing transistors together with this drive coil at the same time is connected as the output stage of an astable @ multivibrator circuit, over wolche the breastfeeding one or aisle files that have been braked, For example, the restlessness of an electric clock can be started and then the circuit itself can in turn be synchronized by the swinging gear folder, and by which the control pulses generated by the control coil can be regenerated at the same time and that the capacitance intermittently applied via the control coil by the first transistor stage of the multivibrator can be discharged.

An expedient inventive training of the subject of the application is seen in the fact that the astable Multivibratorsohaltung from two complementary There are transistors (npn - pnp), which during the functional sequence alternately polarized capacitance are fed back and that the functional sequence due to this capacity in connection with corresponding circuit resistances in time can be regulated finally saw that the one from the control coil and a capacitance formed series circuit on the one hand with the base deo acting on the drive coil Transistor, on the other hand with the one not interconnected with the emitter of this transistor Pole of the supply current source is connected, and that parallel to the control coil and the with it lying in series capacitance one from a resistor and the emitter collector path a second transistor complementary to the first transistor formed in series is laid, the emitter of which is connected to the battery terminal and its base on the one hand via a capacitor with the collector dec first, with the drive coil in series transistor, on the other hand via a resistor to the emitter or is connected to the base of this transistor.

In the drawing documents belonging to the patent application is the invention explained in more detail; The figures show: FIG. 1 the circuit arrangement of a Embodiment of the invention; FIG. 2 shows the circuit arrangement of another embodiment the invention; FIG. 3 shows a particularly expedient one for use in the invention Formation of the arrangement of the mechanical oscillator0 In the circuit arrangement according to Figure l is the series circuit formed from the control coil L1 and the capacitor C1 on the one hand gexchetzt to the base of the transistor T1, which with its collector-emitter path is in series with the drive coil L2, and is energized via this transistor, on the other hand to the pole of the voltage source that is not connected to the emitter of the transistor TI connected in parallel to that formed from the control coil L1 and the capacitor C1 A further series circuit iXt is formed from the transistor T2 and the resistor R1 Laid in series, wherein the transistor is arranged so that its emitter also to the battery pole not connected to the emitter of the transistor Tt comes to rest.

The base of the transistor T2 is on the one hand via a capacitor a2 to the collector of the transistor Tt * on the other hand via the resistor R2 after aem emitter of the transistor Ti out.

The capacitor C3 causes negative feedback from the collector of the transistor T1 according to its base and thus suppresses any tendency for the circuit to oscillate.

The mode of operation of the circuit in detail is now as follows: When When the battery voltage of approx. +1.5 V is applied, the following current flow occurs: + B, control coil L1, capacitor C1, base-emitter path from T1 back to -B.

This current path charges the capacitor C1 and thus the transistor T1 conductive, io that the drive coil L2 is momentarily energized. This comes in addition The following current path is still established: + B, emitter-base path T2, capacitor C2, collector-emitter path T1 -B.

Transistor T2 is thereby also conductive, se that the over the Bamis emitter path of the transistor T1 amplifies the flowing Strem. Both transistors thereby switch reflexively into the conductive state.

When the battery voltage is applied, there is also a current flow via + B, emitter base path from transistor T2, resistor R2 and -B.

As a result of this current flow, the transistor T2 would in itself be weakly conductive In view of the high charging current via C2, the current plays via R2 at the present moment of the function game no essential role.

The conducting state of the transistors T1 and T2 is maintained as long as until the two capacitors C 1 and. C2 are loaded. Through the drive spool L2 applied impulse to the permanent magnet system of the mechanical oscillator, this is brought to the start.

If the capacitors Cl and C2 are now approximately charged, i.e. take the base currents of the transistors T1 and T2 decrease, the potential at the collector-emitter paths rises of both transistors quickly, a process which mutually reflexively favors one another or accelerated and. to an immediate interruption of the two transistors Tl and T2 leads.

"The capacitor C2 is now first again via the following circuit discharged and then charged again with the reverse potential: + B, drive coil L2, capacitor C2, resistor R2, -B.

If the charging voltage of C2 reaches about the Sohwell voltage of the transistor T2, it responds and leads to the following circuit via transistor T2: + B, emitter-collector path from T2, R1, base-emitter path from T1, -B.

The transistor Tt also becomes conductive as a result, the one at its collector-emitter path applied voltage drops rapidly, causing the following feedback loop again comes about: + B, emitter-base section of T2, capacitor C2, collector-emitter section from T1, -B.

The base current through the transistor T2 increases> as a result the transistor T2 is conductive and thus the base current of the transistor also increases T1. Both transistors T1 and T2 are reflexively switched to the conductive state, which is maintained until the capacitor C2 approaches its end of charge achieved. At this moment the voltage across the transistor Tt rises again Process that is transmitted reflexively to the transistor T2 and becomes a rapid Blocking both transistors leads. It can be seen that for the loading process of C2, which leads to an opening of T1 and T2 and thus also an application of pulses of the gear folder via the drive coil L2 brings with it, once the capacitance value from C2 and then the effective resistance of the emitter-bass line of the transistor T2 and the effective resistance of the collector-emitter path of the transistor T1 are decisive are. Both resistance values are relatively low, so that the charging process of C2 and thus the impulses applied to the drive coil L2 and the associated Folder in a very short period of time. The other hand is for the discharge or polarity reversal of the capacitor x C2 essentially the value of the resistor R2 is decisive, which is very high, and thus leads to a relatively slow discharge or Polarity reversal of the capacitor C2 leads.

The above-described functional game, namely continuous loading and Discharge of the capacitor C2 and the associated becoming conductive and blocking of the two transistors T1 and T2 repeats itself continuously with the gear folder standing automatically, until the aisle folder reaches such an amplitude has that the application of the control coil L1 by the oscillating permanent magnetcyetem leads to a synchronization of the astable multivibrator, so that this practical through the continuous application of the transistor T1 directly controlled via the control coil L1 and the capacitor C1 connected upstream of it wird4 The astable mode of operation of the circuit is then interestingf for example if the battery voltage is applied to the gang folder due to any external circumstances, for example by impact or impact or other influences to a standstill has come. In this case, the drive coil L2 is continuously over by the Transistors T1 and T2, together with associated components, formed an astable multivibrator circuit acted upon, so that finally a rocking of the bumped Gear folder is reached and this then a direct control via the control coil L1 the circuit is effected by the vibrating gear folder in the control coil L1 Induction voltage surges generated in alternating directions, which are caused by the valve action the base-emitter diode of the transistor T1 are rectified, and through the Current flows through Cl to a continuous intermittent charge of the capacitor Lead C1 The charging voltage of the capacitor C1 is now effective in the control coil L1 generated control voltage, to the effect that from the voltage surges, which are caused in the control coil, only the peaks become effective. In this way, the effective impulses in the drive coil L2 are greatly reduced, whereby the efficiency of the loading of the aisle folder is favored and thus the power consumption is considerably reduced.

Each time the control coil acts on the base of transistor T1 Ll, the following current path is established via transistor T2: + B, emitter-base path of transistor T2, capacitor C2, collector-emitter path of transistor T1, -B This makes the transistor T2 conductive and. via its collector-emitter path and the resistor R1 increases the base current of the transistor Tl accordingly Influencing takes place regeneratively or reflexively5, i.e. through that in normal operation are no longer astable, but synchronized multivibrator switching the current pulses supplied to the drive coil L2 compared to those from the control coil Ll entered induction pulses effectively steepened.

The natural frequency of the ultivibr'ator circuit operating astable is expediently selected by a factor of 2 ... 10 lower than the frequency of the mechanical Corridor folder. In normal operation of the circuit, in which this is via the Control coil Lt acted upon transistor T1 is controlled, so practically takes place dragging the astable circuit with the effect of accelerating the working frequency. This is also the one in the drive coil L2 through the permanent magnet system of the oscillating The induction voltage generated by the gear folder is important, as this also affects the circuit zureekwektiven This reaction from the drive coil L2 takes place in the sense of an acceleration the equalization processes across the capacitor C2.

Due to the regulating effect of the capacitor Cl, the circuit dimensioned for start-up for a significantly higher current consumption than the actual power requirement after reaching the final amplitude of the mechanical oscillator is equivalent to. This significantly favors and facilitates the start-up also applies to the pulses generated by the astable multivibrator circuit, since these are full in terms of their duration in the rest position of the aisle folder can take effect and not through the resulting from the am-capacitor C1 Charging voltage can be cut.

The at the capacitor Cl by the application of the control coil Lt and the current flow across the base-emitter path of the transistor T1 resulting charging voltage is through the transistor T2 via the emitter-collector path and in series with this lying resistor Rl degraded0 The circuit arrangement according to FIG. 2 differs from that of Figure 1 only in that the resistor R2 is not led to the emitter of the transistor Tl, but to its base. This does not result in any significant differences for the mode of operation of the circuit, the circuit of Figure 2 only offers some better customization options, for example, especially with regard to the discharge of the capacitor C1 and thus the possibility of regulating amplitude differences.

In addition, there is another difference that it normally does Current path leading through resistor R2 to -B in the Sohaltungsanordnung after Fig, 2 runs over the base-emitter path of the transistor Tl.

The differences between the two circuits according to FIGS. 1 and 2 therefore only concern optimal adaptation questions. The mode of action itself is with both Circuits the same, the following dimensioning of a circuit resulted in good ones Operating results: L1 = 1000 turns, 0.06 cul., Outside # 10 mm, inside # 2 mm, winding height 1.5 mm L2 = 2600 turns, 0.035 "," io mm, "2 mm," 1.5 mm T1 = npn transistor, Current gain h21 = 200, at Ic = 1 mA, UCE = 1 V Ucesat 50 mV at Ic = 1 mA T2 = pnp, current gain h21 = 130, at Ic = 1 mA, UCE = 1 V Ucesat 5o mV at Ic = 1 mA C1 = 10 µF C2 - 0.68 pF C3 = 22 nF iAl = 2o k # k2 = 2 M # unrest- # approx. 20 mm number of strokes 36,000 Frequency 5 Hz Frequency of the toggle switch approx. 0.9 Hz The The invention is seen in a combination of the following features: 1. Possibility to start the mechanical gear folder in a manner known per se Via the series connection of control coil L1 and capacitor C1, on the one hand the base of the transistor T1, on the other hand to that with the emitter of the transistor T1 not connected Pole of the voltage source is at the moment the application of the supply voltage O 29 Possibility to start the mechanical gear folder in the case of a standstill that is forced during normal operation, namely by the one of the astable Multivibrator circuit generated relaxation oscillations 3a through pulse regeneration the gearshift, which means that the gear folder is swung up quickly with small amplitudes and additional steepening of the drive impulses.

4o At full amplitude the regulator controls the astable multiviss brator circuit via the control coil Ll, thereby the possibility of synchronization Switching over a wide range of their natural frequency, with normal tolerances the components of the electronic circuit, 5. possibility of regulating the sensitivity the circuit through the control coil capacitor located in the input circuit of the transistor Tl Combination with parallel discharge path formed by transistor T2 is, thereby reduced dependence of the amplitude on the changes in the supply voltage or the output load.

In Fig. 3 of the drawing documents is a particularly useful one Embodiment of the mechanical gear folder for an electric clock shown.

On a balance shaft t are two opposite prismatic plates 2 and 3 applied, which are small cylindrical or cuboid at the two ends Magnets 4, 5, 6 and 7 with opposite axially parallel, uneven polarity have applied. In the by the magnets 4, 5 on the one hand and the magnets 6, 7 the air gap formed on the other hand, control coil L1 and drive coil L2 are housed, both of which are acted upon by the complementary fields of the magnets 4-7.

The coils L1 and L2 are arranged diametrically opposite one another and the buoyant position of the gear folder, which is under the restoring force of a spiral spring is chosen so that in each case a diametrically opposite winding bundle of The drive and control coil is centered in the air gap of the permanent magnets; Parts 2 and 3 are expediently made of soft magnetic material, because this the magnetic circuit resistance is reduced and at the same time a desired shielding effect can be achieved9 To achieve better Aussteen through the control coil L1, as well as to improve the isochronism behavior, is expedient for the gang folder a frequency above the normal balance oscillator frequencies, for example such a tone is assigned 5 Hz. The polarization of magnets 4 - 7 or connection sequence of the coils L1 and L2 is chosen so that the introductory drive pulse, which causes the oscillator to start up, a movement of the magnet system 6, 7 caused by the center of the drive coil L2 we #, the magnets 6, 7 thus practically a repulsion learned from the drive coil L2. The control coil L1 is connected in such a way that that the generated in it by the simultaneous movement of the magnets 4.5 inductive voltage pulse the effect of the current surge generated in the drive coil L2 supports the transistor T1 as @ additionally applied.

By which wiring are unwanted overlaps between the current impulse initiating the drive in the drive coil L2 and the one during overshoot of the control coil L1 resulting from the initial movement directed towards the means Voltage impulse avoided and at the same time the starting movement due to the positive reaction favored.

It is an advantageous arrangement if the plates 2 and 3 are made of hech permeable magnetic material are made and the axially unequally polarized opposing magnets 4.5 and 6.7 within the plates are chosen so that the two fields generated by these four magnets ii air gap add up, the plates 2 and 3 act as practical inferences. This results in higher inductance values in the air gaps and a higher induced control voltage in the control coil L1 and at the same time. more intensive application of the magnet system through the drive coil L2. In addition, the same polarization is less than that Observation of the operating mode proposed in understanding resulting connection rim of the coils L1 and L2 a starting and operating loading of the oscillator supporting, direct inductive or transformer coupling between the Coils L1 and L2 via the magnetic field created by the four magnets 4-7 is formed, brings with it.

Such a training of the balance wheel would also be possible respectively.

expedient, in which the 4 magnets, diametrically opposite, on two magnetic carrier disks made of soft magnetic material and attached next to each other on the rest shaft Werksteff high permeability are attached. In other words, this would mean that in this case the prismatic plate @ which carry the magnets to be circular Slices are supplemented.

It is also possible, instead of the strictly separate arrangement of the two opposing coils L1 and L2 have such a kembinated connection forgetting that, for example, one drive and one control coil either in kentric Grounding or in a training as superposed, flat discs both sides of the transducer instead of just one control coil L1 and one Drive coil L2 are arranged.

It would also be possible to wind the two coils bifilar together, se that there is a close coupling between drive and control coil, and thus - taking into account the corresponding polarities and the connecting rims of the individual coils - a further benefit of the start-up and the operating conditions is possible. An earth connection is also conceivable in which the coils are only on one Side are coupled, then either on one side only one coil L1, on the on the other hand, however, a drive coil inductively coupled with a further control coil L2 or vice versa, is available.

Such further developments make it possible to act on to get the necessary control voltage of the transistors in their correct value, or vice versa, to ensure the necessary application of the permanent magnet system and in this way a coordination between the coils and the permanent magnet system reach.

The main distributions achieved by the subject matter of the application are: 1. Automatic starting of the mechanical ginger in an and for known way when applying the supply voltage and control option of the Amplitude.

2. Automatic start-up of the mechanical goalkeeper when forced Standstill due to the astable multivibrator circuit.

3. Regeneration of the control pulses generated by the control coil, This means that at small amplitudes there is rapid build-up and sharp in Nermal operation Appointment of the guardian.

4. In normal operation, safe control or synchronization of the circuit by the control coil, quite independent of the natural frequency of the multivibrater, thereby synchronous operation of the circuit over a wide range of its natural frequency, in the case of internal catalog delays in the components.

5. Low power consumption of the circuit grounding.
