DAVIES COLLISON CAVE Patent Trade Mark Attorneys Level 10, 10 Barrack Street SYDNEY NSW 2000 Method and device for regenerating voltage supply elements in the form of primary elements The following statement is a full description of this invention, including the best method of performing it known to me:- 5020 METHOD AND DEVICE FOR REGENERATING VOLTAGE SUPPLY ELEMENTS IN THE FORM OF PRIMARY ELEMENTS Background of the Invention The present invention relates to a method for regenerating voltage supply elements in the form of primary elements with electrical energy supplied thereto as well as a device for performing the described method.
Primary elements, respectively, primary voltage sources, have become indispensible in daily life and are used with different devices, apparatus and appliances in order to supply such devices, apparatus or appliances with electric energy. Primary voltage sources of the aforementioned kind are, for example, manganese, alkali, zinc-carbon or other elements which all have in common that after a certain amount of operating time only such a low voltage is present at their poles that the desired operation of the consuming device connected thereto is no longer possible.
Due to the electro-chemical changes in the interior of such primary elements, the initial voltage is reduced and a change of the inner resistance of the elements takes place so that the 1 output power of such elements is reduced parallel to the nominal voltage. Typically, a primary element in its initial unloaded state has a voltage of 1.5 V. An element of this kind is considered spent when the voltage sinks to approximately 1 to 1.2 V.
In general, such spent elements are without second thoughts disposed in domestic or industrial waste which, in view of the material and the -hemical composition of the components of such primary elements, is highly objectionable, respectively, even dangerous with respect to environmental considerations. In the recent pest efforts have been made to collect such spent elements at special collection locations in order to subject them to a controlled recycling process; however, an element of the aforementioned kind is often considered spent, as mentioned above, when the voltage drops below 1 to 1.2 V even though the components of the elements are still intact.
In this context it should be noted that the voltage of the primary element which changes over time of use and the accompanying reduction of current supply is essentially only determined by the reactions taking place in the interior of the 2 element during the time of use.
Various attempts have been undertaken and various methods have been suggested for recycling the primary voltage supply elements, that are spent in the aforementioned sense, with the goal that these elements should be able to supply power for a further period of time. However, all methods known to date have the disadvantage that a truly effective regeneration is not possible or possible only to a limited extent.
It is thus an object of the present invention to provide a method and a device of the S. aforementioned kind for the regeneration of primary elements with which a regeneration is possible such that the power output of essentially .unused primary voltage supply elements can be reached, whereby the method and the device should be simple and inexpensive to perform, respectively, to manufacture so that they can be mass-produced at low cost and find wide-spread •o use.
Brief Description of the Drawings This object, and other objects and advantages of the present invention, will appear more clearly from the following specification in conjunction 3 with the accompanying drawings, in which: Fig. 1 shows a device for performing the method for regenerating voltage supply elements in a block diagram; Fig. 2 shows an embodiment of a device shown in Fig. 1 with details of the circuitry; Fig. 3 shows the current as a function of time for the primary voltage supply element upon a load of 6 ohm corresponding to 250 mA, whereby curve A shows a new voltage source, curve B shows the current after a first regeneration process, and curve C shows the current after a second regeneration process; and Fig. 4 shows a plan view of a housing of the device for 0 Sreceiving a plurality of voltage supply elements to be regenerated.

furthermore advantageously possible that, in addition to saving raw materials, the disposal problem is also reduced, and the primary element must be disposed of only after multiple regeneration processes when in fact the inner, irreparable destruction has been observed.
In a preferred embodiment of the invention the voltage impulses are designed such that they have a short ascending time, respectively, a short descending time, the voltage impulses have very steep flanks that contribute substantially to the increase of the regenerating effect.

Advantageously, the frequency of the voltage impulses is also variable and may be selected, for example, to be within a preferred range of 2 to 200 Hz.
The regenerating current should be adjustable preferably within a range of 5 x 10 2 A to 15 A.
It is also possible to, for example, adjust the range of the regenerating current at a fixed rate, 7 -8to perform the regeneration process with a constantly pulsed current and with changing voltage impulse amplitudes that are adjusted as a function of the regenerating state of the primary element. However, it is also advantageously possible to allow for an automatic adjustment of the regenerating current as a function of the inner resistance of the voltage source to be regenerated whereby the voltage impulses are preset to have a constant amplitude.
In another aspect, there is provided a device for regenerating a voltage supply in the form of a primary element by supplying the primary element with electric energy in accordance with the above described method, the inventive device being primarily characterised by: a low resistance dc voltage source; a switching device having an input and an output for connecting the switching device to a pole of the primary element to be regenerated, the output delivering a S 15 sequence of voltage impulses; the low resistance dc voltage source connected to the input; and a timing generator connected to the switching device for timing the switching device.

Such a device will be commonly supplied via electric networks, present everywhere, with the required primary energy so that no expensive technical measures are required for a respective adaptation, commercial voltage transformers and/or adapters can be used.
ye ',the switching device has an adjusting member for setting the amplitude of the voltage impulses and 4 also comprises gig• a control device for controlling the regenerating current if desired to maintain the current at a constant level while the amplitude of the voltage impulses is adjusted as a function of the degree of regeneration of the primary elements to be o e regenerated.
The characteristics (parameters) of the control of the control device can advantageously be selected as a function of the degree of regeneration of the voltage supply element and the resulting changing inner resistance. However, it is also possible to select a different control characteristic, if needed, as a function of the 10 2 J voltage supply element to be regenerated, respectively, if so desired, and when special regenerating characteristics are desired or necessary.
It is also adVoogou that the time period for regenerating the voltage supply element to be regenerated can be predetermined, respectively; set to a certain time period that is adjustable with a timing member so that after completion of a regenerating process in a quasi automatic manner the regeneration is terminated, the primary voltage source (electric energy source) is switched off.
Description of Preferred Embodiments The present invention will now be described in detail with the aid of several specific embodiments utilizing Figures 1 through 4.
The device 10 for performing the method of the present invention will first be described with the aid of Fig. 1 representing a block diagram.
A low resistance dc primary voltage source 23 may be in the form of a suitably dimensioned adapter that can be connected with its input to a suitable ac network in a suitable manner. The dc voltage source 23 supplies in a known manner a dc signal 11 2 A- y 13 to the input 17 of a switching device 14. The switching device 14 is directly controlled by a timing generator 15 which functions such that the dc signal 13 is changed into a sequence of voltage impulses 18 at the output 16 which is adjustable with respect to the impulse duration via an adjusting member 21 that also cooperates with the timed switching device 14. The impulse duration of a semi-period of the impulse sequence 18 is for example between 10- 3 to 2 x 10 3 seconds long.
The adjusting member 21 may also be provided with adjusting elements, respectively, control members with which the regenerating current is adjustable within a range of 5 x 10- 2 A to 15 A.
The timing generator 15 is also adjustable, respectively, controllable such that with it the *frequency of the voltage impulses of the sequence 18 is adjustable, for example, in the range of 2 to 200 Hz.
The timing member 22 is connected to a switch 24 such that the voltage impulse sequence 18 from o the output 16 of the timed switching device 14 is connected to a pole 19 of the voltage supply element 11 to be regenerated. The other pole of the voltage source 11 to be regenerated is 12 connected in a conventional manner to the other pole of the do voltage source 23, in the shown example to its mass. The timing member 22 may be embodied in an adjustable form so that in a predetermined manner the regenerating process, th charging of the voltage supply element 11 to be regenerated with the sequence 18 of voltage impulses can be performed at a predetermined time period. When the end of the predetermined time period is reached, the electrical switch 24 which was closed due to the *opressure of the time interval key, is open so that automatically an interruption of the supply of the voltage impulse sequence 18 to the voltage supply element 11 to be regenerated takes place.
It should be noted that the device 10 may also be embodied such that it is possible to oooe adjust the regenerating current at a constant level as a function of the inner resistance of the voltage supply element 11 to be regenerated (constant current charging mode, respectively, constant current regenerating mode). However, the current may also be adjustable, if needed, or automatically adjustable corresponding to the changing inner resistance of the voltage supply 13 element 11 to be regenerated during the regenerating process.
Fig. 2 shows the device according to Fig. 1 in a detailed circuit diagram embodiment.
Voltage is supplied to the device via a conventional supply network to which a transformer is connected. With one pole of the secondary side of the transformer 25 two capacitors 25 are connected and with the other pole two diodes are connected. Together the elements 25, 30 form in a known manner a rectifier-voltage doubler.
Accordingly, as known per se, a low resistance dc voltage source for supplying voltage to the following functional elements of the device 10 is provided.
The generation and the formation of the steep-flanked impulses for the highly effective regeneration effect is carried out with the timing generator, respectively, impulse generator 0oe*0 The generator 15 works as an asymmetric multi vibrator together with the transistors 27 and 28 S•and generates and forms the required impulses with ooo an impulse sequence frequency of 2 to 5 Hz. Via further impulse forming circuits these are subsequently guided to the electronic switch 14 14 and amplified. Subsequently, these voltage impulses are then guided into the part of the device into which the primary elements to be regenerated are inserted. In order to protect the device 10 and the primary elements to be regenerated (the voltage supply elements 11), the circuit of the device 10 may be provided with a so-called automatic turn-off device 29 that limits the regenerating, respectively, quick-loading process to a predetermined time period, for example, a maximum of 25 minutes. If need be, by pressing the timing key 31 one more time, the regenerating, respectively, quick-charging process may be activated again for the predetermined time period.
Fig. 3 shows the course of the initial .voltage of a voltage supply element as a function of time for a discharging process over a load resistance of 6 ohm corresponding to approximately 250 mA. After approximately 12 hours the voltage of the voltage supply element 11 has been reduced 9 from 1.5 V to 1.2 V. 250 mA correspond approximately to the current consumption of an incandescent lightbulb that is typically used in flashlights. The first discharge curve of the 15 voltage source 11 is represented by curve A in Fig. 3. Curve A represents a new voltage supply element 11 that has never been usec' After a first regeneration process over a time period of approximately 20 minutes, the regenerated voltage supply element that has been regenerated with the inventive method and the inventive device provides a nominal voltage of approximately 1.5 V. A subsequent discharge of the regenerated voltage source 11 with the same load parameters for a time period of 12 hours is represented in curve B. Curve B is almost ^o identical to the first load curve A. A subsequent second regenerating process with the inventive method and device 10 over a time period of minutes again results in a nominal voltage of approximately 1.5 V whereby with the same load parameters a curve C results that only slightly deviates from the previous curves A and B.
Experiments have shown that commercially available primary elements of good quality can be regenerated at least 10 times in the aforedescribed manner without exhibiting a significant power output decrease.
With the inventive method it is thus possible 16 to reverse the chemical, respectively, electrochemical reactions taking place in the interior of the primary elements 11. The normal electrochemical reactions occurring with an electrical consuming device connected to primary elements is the formation of deposits on electrodes which deposits have an insulating effect. With the inventive method and the inventive device 10 the electrodes are freed of the insulating deposits so that an almost complete regeneration of its initial power output, respectively, capacity is.
obtainable.
Fig. 4 shows a housing for the device 10 for receiving a plurality of voltage supply elements 11. The housing may recreive different voltage supply elements 11 which may be regenerated individually or simultaneously.
It should be noted that the inventive method and the inventive device 10 are not only suitable for regenerating primary elements 11, but are also suitable for a quick-charging of secondary voltage 5 0 supply elements, different types of accumulators, without deviating from the inventive principle of regeneration, respectively, recharging with voltage impulses over a certain 17 period of time at a predetermined impulse duration, amplitude, and frequency etc. The inventive device and the inventive method have been very effective and are therefore suitable for charging or recharging secondary voltage supply elements.
The present invention is, of course, in no way restricted to the specific disclosure of the specification and drawings, but also encompasses any modifications within the scope of the appended claims.
