  • the term winding on a core includes any arrangement of a conductor in the area of a magnetizable core which is capable of magnetizing the core upon the passage of electric current through the conductor, or of being the source of an electric current by induction when the magnetization of the core is changed.
  • Every set of core assemblies is associated with a control member, more speciically a magnetizing device which is capable of increasing a normal state of comparatively low remanent magnetization of a predetermined number of cores in the respective set of core assemblies, depending upon the position of this magnetizing member in relation to the core assemblies.
  • the magnetizing members consist of channel-shaped bars 11, 12, 13, respectively, which are movable in longitudinal direction along the pertaining set of core assemblies. The latter are mounted, by means not shown, so as to be located in transverse position within the hollow portion of the respective channel bar 11, 12, 13, respectively.

  • FIG. 4 where one section of channel 11 is illustrated in plan view and showing, for the purpose of explanation, the annular core 1@ in a position parallel with the bottom of the channel 11. This orientation of the annular core 1t? is quite as suitable as the position perpendicular to the bottom of the channel 11 illustrated in FIG. '1.
  • the arrows indicate both the magnetic flux in the annular core 10 and the magnetic field lines between the oppositely magnetized walls of the channel 11.
  • the magnetizing members do not have to be permanently magnetized bars as described above, but may also be electromagnetic devices somewhat as shown by FIG. lb.
  • the channelshaped member is composed of a wall 11 and an opposite wall 11, connected at the bottom by a non-magnetic strip 11"', each of the wall members 11 and 11 carrying at its rear end a coil 11b and 11C, respectively, which are connected with each other and with a source of direct current potential in such a manner that by application of electrical energy to the coils 11b and 11a ⁇ the entire side walls 11 and 11 are magnetized so as to constitute magnetically opposite poles.

  • FIG. 1a illustrates, by way of example, diagrammatically channel 11 with an attached extension rod a having rack teeth along one edge whereby it is in driving engagement with a sprocket b which may be turned by means of a shaft d in driving connection with control members of the respective calculating machine.
  • a return spring c may be provided for holding the member 11 in such adjusted position until the pawl e is moved out of engagement whereafter the spring c would return the member 11 to its normal position.
  • FIG. 1 illustrates a condition of the arrangement in which the members 11, 12 and 13 have been adjusted to specific positions as follows:
  • the member 11 which is assigned to the lowest or first order position A is in a position in which the first core 100 is in alignment with the notches 11a
  • the member 12 is in a position in which the core 102 is in alignment with the pertaining notches
  • member 13 is in a position in which the core 101 is in such a position.
  • the just named three cores are the ones which are not iniiuenced by the magnetic field existing between the walls of the pertaining magnetizing members, and these are also the cores which are selected under these conditions to transmit digit representing input or read-out pulses to the respective output lines.
  • a read-out or input pulse 6%' which is shown in FIG. 1 to be a negative pulse, applied to input line 100 would only magnetize the core 100 and thus generate an output pulse from the output line OA for the first order position; similarly a read-out or input pulse applied to the input line 101 would only magnetize the core 101 and thus produce an output pulse from the output line OC assigned to the order position C; and finally a read-out or input pulse applied to the input line 102 would only magnetize the core 102 and thus generate an output pulse from the output line OB assigned to the order position B. Consequently, in this manner a number 120 has been read out in correct order arrangement and corresponding pulses have been delivered through the output lines of the arrangement.
  • the annular cores are made preferably of magnetically soft material the magnetic characteristics whereof will be explained now with reference to FIG. 3.
  • a magnetically soft core of this type i.e. a core made of a material having a non-rectangular hysteresis loop characteristic will, after having been magnetized in positive direction e.g. to the diagram point Bm, return to its normal remanent magnetic state -i-Br as soon as the magnetizing field has been removed.

  • the respective input windings are symbolized by a slanting short line marked WE.
  • the individual cores are indicated by a vertical line marked 1E).
  • the respective output windings WA are likewise symbolized by a short slanting line across the core line.
  • the columns of the matrix are constituted by the series connected output windings WA, and accordingly by tlie'rneandering output lines OA, OB OL which are all connected at one end to the common conductor OX which is also connected with the above mentioned line R and which terminate, at the bottom of the diagram in a series of output amplifiers V assigned to the decimal order positions A, I3, C L.
  • a negative output pulse 60 is indicated near the output amplifier VL.
  • the strength of the output signal is proportional to the changes of magnetic iiux in the core which, in turn, are proportional to the differences -j-Bm--j-Br, marked as Ben, and B3-B2 marked in FIG. 3 as Bmeff. Therefore, in a core influenced by the application of an external -field the ratio between effective and ineffective magnetization is equal to the ratio between the Values 'l-Bm* -l-Br and BgFBZ.
  • the hysteresis loop characteristic of the core material displays in the area above Bm a nearly rectilinear form so that the change of flux due to magnetization beyond the point Bm is as small as possible. It is also of great advantage to utilize in the arrangement according to the invention annular cores because this type or core possesses a great permeability and because in these cores the difference between the permeability of the core exposed to an external field and the core non-exposed to an external field is particularly large.
  • the matrix switch arrangement according to the invention and described above is not only useful as a device for transferring digit signals, but can be used with equal advantage directly as a digit storage device.

  • a conventional returning bar controlling all of the movable magnetizing means could be used.
  • An arrangement as just described may be of particular advantage if a particular calculation factor is to be kept available through a sequence of several calculating operations.
  • the input windings could be used as output windings while the output windings could be used as input windings.
  • an input pulse applied simultaneously to all of the windings WA via all the lines OA, OB OL would generate output pulses in those windings WE only which are not previously rendered ineffective by corresponding adjustment of the shiftable magnetizing members 1I, 12, 13 etc.
  • simultaneously output pulses representing preselected digit values would be delivered simultaneously through the respective lines 100, 101, 102 109.
  • the accessory equipment like output ampliliers and input ampliliers etc. would have to be either omitted or replaced by other suitable devices.
  • rectifier diodes 50 and Sti' are provided in the input and output lines.
  • the polarity thereof corresponds to the polarity of the respective pulses.
  • Their main purpose is to serve as decoupling means so that eg. pulses appearing when the magnetization of a core drops from -l-Bm to -j-Br remain without effect.
  • the arrangement is designed to serve as a device for controlling the order position of digit value signals transmitted between cooperating devices.
  • the heavy frame line indicates a matrix arrangement of the general type illustrated by FIG. 2 but having only three columns A, B, C and eight rows marked A', B', C H'.
  • the series connected output lines are used as input lines and the input lines of FIG. 2 are used as output lines as indicated by the arrows in FIG. 5. It is to be assumed that from an input device assumed to be arranged on the side marked I and operating With three-order numbers digit representing signals composed of pulse sequences of corresponding pulse numbers are applied to the matrix.
