Description

The invention relates to an information storage device. Ee Although many information stores are already known, most of them have one or the other disadvantage. Of the The invention is therefore based on the object of creating an improved information memory.

The information memory according to the invention contains a number of magnetic cores or the like «, which windings to change associated with their magnetic state. In relation to the cores are arranged according to the information to be stored conductors that deliver an electrical output signal if the magnetic state of any or

of several selected nuclei changes, but does not provide an output signal if the magnetic state of any unselected kernel changes.

The information is stored by a suitable arrangement of the conductors in Sezug on the cores. The electrical output signal and / or the absence of an electrical output signal can be used in a suitable manner to provide information be used.

Preferably the cores are in the form of a shift register arranged and at least one core has an opposite polarity with respect to the rest of the cores. The shift register is actuated by one or more pulses applied to the windings. Each actuation impulse causes that the magnetic state of opposite polarity is transmitted from the core concerned to the next core will.

The cores can be made of Perrit with a rectangular hysteresis loop or a similar magnet material.

The information can be permanently stored by arranging a conductor so that it is selected by the magnetic flux Nuclei or selected groups of nuclei um · chi ο seen, however

from the magnetic flux of other cores or groups of cores is enclosed. If closed cores are used, For example toroidal cores, the conductor can be passed through the core if it is affected by the magnetic flux of the core is to be enclosed, or it can also be arranged outside the core, if the conductor is not to be enclosed by the magnetic flux.

To store words, letters and / or numbers, you must first assign a code to each search letter of the alphabet and each required number, which consists of different combinations of two symbols, for example the symbols "0" and ^M 1 ⁿ . Line change in the electrical output signals A change in the polarity of a core whose magnetic field surrounds a conductor is interpreted as one of these two symbols, for example as ^M 1 ". The absence of an electrical output signal when the polarity of a core whose magnetic field does not surround a conductor is changed is then interpreted as the other symbol ^H 0 ".

Words can thus be stored for each word by properly arranging a conductor. Each conductor is enclosed or not enclosed by the magnetic flux of successive cores, so that if the polarity of the cores is changed one receives the required code for each subsequent letter of the word as a combination of two symbols that the in

Question coming forth. For example, the letter ^H a "can be represented by the code" 110011. "Six cores are required to store this letter and a conductor is arranged so that it is surrounded by the flow of the first two and the plumbing two of the six cores, but not from the plus β of the two middle nuclei In a similar way, numbers can also be stored.

To represent the same number of words or numbers any required number of conductors can be assigned to the cores. All or some words can be in turn after being read in any required sequence by appropriate selection of conductors * It is of course that Reading only one word or only one number possible. The selection of conductors and the connection of the conductors to ancillary equipment can be made in any suitable manner.

You conductors can be connected to a teleprinter, through which the information is expressed in the form of letters and numbers. The above-mentioned type of code becomes common used in teleprinter directions and a teleprinter can therefore be assigned to the information store according to the invention. The cores are preferably switched over with teletype speed

909826/1041

Instead of the code systems described above, nan can also be used assign to each number of information stored in a given number of actuation pulses * i.e. a given number of actuation pulses represents any given whole number or group of whole numbers Conductor can then be appropriately positioned in relation to the cores so that it is surrounded by the magnetic flux of certain cores, but not by the magnetic flux of the other cores sen is fed to the core windings to switch the cores, one receives a number of output pulses from the conductor, which are related in a predetermined way to the number of actuation pulses. The output pulses can be a counter from which information is then obtained in any required manner. In this way, information in ? orm of tables can be saved *

The information memory according to the present invention is particularly suitable for optical emission spectral apparatus for the analysis of metal samples. The percentages of the various elements are obtained one after the other, for example over 30 elements, and it would be very convenient to

if the name and percentage are each in one Metal sample of the element present together with headings and other descriptive information from a telex is printed out, for example as follows » Silicon ... 0.13 Sulfur ... 0.012 etc.

The name of any element that may be present in a metal sample and each to be recorded, if any word required for analysis can be appropriately printed out by a telex.

Information about the proportion of each in a metal sample existing element is obtained in the form of digital values from one with the recording instrument of the spectrometer related unit. Pie digital values supplied by the spectrometer represent a certain percentage of an element. For each element a conductor is provided which corresponds to the cores or the percentage of the element is assigned depending on the table indicating digital values. To obtain information about the percentage of an element becomes a number corresponding to the digital value supplied by the spectrometer of actuation pulses fed to the core windings. The output impulses that are then given by the associated element Head receives «then represent the requested information.

Host, for example, the silicon content of a metal sample searched, then the spectrometer receives a digital count corresponding to the silicon content of the sample. Ansohlieeeend, for example, becomes part of a typical Table shows the relationship between the silicon content of a sample and that provided by the spectrometer indicating digital count.

It can be seen that up to a count of 9 the silicon content is 0 and a count of 10 is one Represents silicon content of 0.01. However, every higher count does not represent a higher silicon content Aar · For example counts 11, 12 and 13 all correspond to a silicon content of 0.02. The silicon content only increases in the table always around a unit.

You table is saved by a ladder like this is arranged so that it is not enclosed in a core arrangement by the flows of cores 1 -9t 12 and 13, 15 and 16, but by the flows of cores 10 and 11 » of the core U and the core 17 * If the magnetic state of the core arrangement is changed one after the other as in a shift register, then only core numbers 10, 11, 14 and 17 the induction of an electrical output pulse in the head. Each output pulse represents an increase in the silicon content of 0.01. They become output pulses fed to a counter for addition.

In a table in which the information values, for example the content of an element in a metal sample, increase by 1 or 2, a so-called "1 ^M wire and a so-called" 2 "wire can be provided arranged so that it is enclosed only by the flow of the nuclei * in which an increase around the unit 1 is recorded, the

909826/10 4 1

2-wire is, however, arranged such that it is enclosed only by the flues of the cores "in which an increase is recorded by the unit 2 therefore · A in 1-wire induced pulse corresponds to an increase of the unit 1, whereas in the 2 -Wire induced impulse corresponds to an increase of the unit 2. If a three unit increase is recorded in any core. To _1, the 1-wire and 2-wire can be arranged so that they are both enclosed in the flow of that core.

The operation of a spectrum analyzer requires some time before constant results are obtained. During this time, you can already use a telex or the like to find out the name of the person you have just examined Print out the element so that no time is lost.

It is very important that the analysis of a steel sample is known as soon as possible. The arrangement according to the Invention now delivers this analysis in a very short time4

For the above-mentioned analysis of steel samples, a separate line is required for the name of each element * If the name is to be available in more than one language, a separate leader is required for each name in each language

909826/1041

There is also at least one other leader for the table of the digital values depending on the percentage of each element. If 1- and 2-wire are used, two conductors are required for each table.

The invention will now be explained in more detail with reference to drawings explained in which show:

Fig. 1 shows an embodiment of an information memory according to

of the invention and Fig. 2 shows another embodiment of an information memory according to the invention.

In Fig. 1 are a number of permanently magnetizable Toroidal cores 1a, 1b, ... 1h shown with foldable polarity, each with coils 2a, 2b, ... 2h several turns and are enclosed by coils 3a, 3b, ... 3h with only one turn. The coil 2a of the core 1a lies parallel to the coil 3b of the core 1b. In a similar way the multi-turn coil of each other core is parallel to the one-turn coil Coil of the immediately following core of the core assembly. The multi-turn coil 2h of the last core 1h of the arrangement lies parallel to the coil 3a of the first core 1a, which has only a single turn,

909826/1041

Each parallel circuit is connected in series with the next but one parallel circuit, eo the parallel circuit 2a-3 "b is in series with the parallel circuit 2c-3d, which in turn is in series with 2e-3f, while this in turn is in series with 2g-3h Parallel circles 2b-3c are in series with 2d-3e, which in turn is in series su 2f-3g »A series of actuation pulses can be fed alternately to lines 4 and 5. The magnetic cores and the magnetic coils and arranged in such a way that they a The coils 2a.

Eb should now be assumed that the magnetic cores 1b ... 1h have the same polarity while the core 1a has opposite polarity. A pulse fed to the line 4 is generated in the multiple windings Coils 2a, 2c, 2e and 2g successive voltages and therefore magnetic fluxes, whereby only the polarity of the Core 1a is reversed, but not that of the other cores. The change in flux in the core 1a has a current flow through the coil 3b, which has only a single turn, in such a coil Direction as a result that the polarity of the core 1b is reversed. The cores 1a, 1c ... 1h now all have the same

909826/1041

Polarity, while 4 core 1b now has a reversed polarity on know ι i.e. the state of reverse polarity was transferred to the core 1b.

A pulse fed to line 5 generates in the off coils 2b, 2d, 2f, 2h consisting of several windings successive voltages and only causes a reversal of the polarity of the cores 1b »but no reversal of the Polarity of the other nuclei. By reversing the

Polarity occurring flux change in the core 1b becomes a Current flow through the only one turn having Coil 3c induced in such a direction that the polarity of the core 1c is reversed The cores 1a, 1b, 1d .. · 1h now all have the same polarity, while the state of the reverse polarity has now been transferred to the core 1c.

With each subsequent pulse, the state of reverse polarity is transferred to the next core, until this state schlieselich reach the core 1h · ^v om core 1h of the state is transferred back to the core 1a.

To transfer the opposite polarity in To prevent the opposite direction, rectifiers 7 are provided.

909826/10 4 1

Through the magnetic cores 1a, 1b, 1d, 1f and 1g is a Conductor 6 passed through · However, conductor 6 does not extend through cores 1c, 1e and 1h. In the head 6 is an electrical output signal is induced when the state of opposite polarity is applied to each of the nuclei 1a, 1b, 1d, 1f and 1g is transmitted. However, no signal is induced if the opposite polarity state is transferred to the cores 1c, 1e and 1h.

The above guidance of the conductor 6 corresponds to the code "11010110",

Pureine would present information in the form of a table each of the magnetic cores 1a and 1b has an output signal in the conductor 6 produce. The core 1c would not deliver a pulse, while the core 1d would again provide a pulse. Neither The core 1e and the core 1h would deliver momentum, while on the other hand the cores 1f and 1g would in turn each deliver a pulse.

When the opposite polarity state is transferred from one core to the next following core, the Flux decrease in the first core in the conductor 6 induces an emf which is opposite to the emf caused by the next one Core in the conductor 6 is induced. TTm this process on Reduce minimum dimensions, one can reduce the rate of disintegration

Make the flow in the first core slower than the build-up speed of the river in the second core. This can be done by appropriately setting the turns disproportionate between the Cores are carried out.

Dor opposite polarity state can be at a time not only transferred to one core, but also to two or more cores. Both cores can be used with a single hole as well as with multiple holes. Per conductor 6 can have a core, for example the core 1a, in the form of one or more turns.

The information memory according to the invention can also be used to store information temporarily or variably save. For this purpose, each core in the core arrangement can be assigned its own conductor, the one from the river of one's own core is enclosed. A switch is also provided in each conductor.

Because every conductor is surrounded by the magnetic field of its own core If the magnetic state θ of the core changes, an EKE is induced in the conductor. By opening dee in Heine The conductor is shut down and no electrical output signal can be taken from the conductor · By closing the in line with the conductor Switch, the conductor is switched to the operating state.

909828/1 Ό Α 1

out so that you get an electrical output signal from the Ladder can receive “by opening and closing appropriately of the switch, the stored information can be changed in the usual way.

Such an arrangement makes it possible to introduce a number of whole numbers of information which are available simultaneously in the form of their own series. The various wires can be parallel to form a unit be shaded. A preferred arrangement for temporary or variable information storage is now based on Fig. 2 explains in more detail.

A number of toroidal cores 8a, 8b ... 8h are one Shift registers connected together in the same area as in FIG. For the sake of simplicity, the magnetic core windings are omitted in FIG.

Conductors 9a, 9b ... 9h are passed through the cores 8a ... 8h. In doing so, each of these conductors is guided by the flow of his own Enclosed core. Die.Lleiter 9a ... 9h are arranged parallel to one another and provided with output lines 10, 11. In Row to the conductors 9a ... 9h are switches 12a ... 12h.
