1,141,903. Magnetic storage arrangements; automatic exchange systems. WESTERN ELECTRIC CO. Inc. 26 May, 1966 [15 June, 1965], No. 23535/66. Headings H3B and H4K. A calling line identification arrangement comprises first and second shift registers SR1, SR2, Fig. 1, of the movable domain wall type, with each subscriber's line L1, L2 ... connected to a different scan position in the first register SR1, those lines which are in the offhook condition establishing a reversed domain pattern which is propagated periodically by multiphase advance clock driver 33 through both registers in turn. A domain reversed by off hook current appears at lines 22 and 24 in turn during a shift cycle, its time position denoting the scan position and thus the line identity. No domains are propagated when all lines are on-hook. In operation, a line newly off-hook is identified by a pulse in line 22 alone when the domain reaches the end of shift register SR1 during the shift cycle immediately following, while continuance of the off-hook condition during subsequent cycles is denoted by the simultaneous appearance of pulses in lines 22 and 24. When a subscriber's line goes on-hook the new condition is denoted in the shift cycle immediately following by a pulse on line 24 alone. The newly off-hook or on-hook conditions of a line are identified by a circuit comprising exclusive OR gate 20 and AND gates 21, 23, 27, 28, each condition causing a central processor 12 to appropriately control a switching matrix 11. Each register may comprise a respective wire of ferromagnetic material having a rectangular hysteresis characteristic, or may comprise a single wire of such material with an intermediate sense coil connected to line 22. The magnetic wire 100, Fig. 2, is is coupled at spaced positions by coils connected to respective lines 1, 2 ... and is also coupled at these spaced positions by a common coil 101 connected to a nucleation driver 14, Fig. 1. When a line is in the off-hook condition, e.g. line 2, the line current is insufficient by itself to establish a reversed domain, but such a domain is established when a periodic pulse is received from the nucleation driver. A bias may additionally be used. In a modification, Fig. 5, each line La-Ld is coupled to a separate magnetic wire 100a-100d, each of a different length, so that pulses are induced in a common sense winding S, in turn, when the reversed domains established by off-hook lines are advanced by a multiphase advance clock driver 133 to the end of the register. In this arrangement the nucleation driver establishes a reversed domain in each magnetic wire by applying a periodic pulse to coil N, and domains associated with off-hook lines La-Ld are expanded by the offhook currents. Only expanded domains are propagated by the multiphase advance pulses applied to coils P2, P1 from advance clock driver 133, the stationary domains at the onhook positions being erased by a reset pulse in coil R from a reset driver 215.

1,183,486. Magnetic storage apparatus; repertory diallers. WESTERN ELECTRIC CO. Inc. 16 May, 1967 [16 May, 1966], No. 22651/37. Headings H3B and H4K. In a repertory dialler a memory comprises a plurality of magnetic domain wall wires in which information is written into a write portion of all the wires simultaneously but is moved along only a selected wire for read out and storage. The dialler includes a magnetic domain wall wire DW for each telephone number stored, only one being shown in Fig. 1 and seven input conductors L1 to L4 and H1 to H3 are coupled to all the domain wall wires, Fig. 2 (not shown), the depression of a a digit select button in the push-button array of a subscriber's V.F. sender, Fig. 6 (not shown), corresponding to the actuation of a coded pair of the seven conductors. Thus a telephone number is stored as a plurality of coded reverse domain pairs by pulsing two of the input conductors. The two reverse domains of the first digit are preceded by a marker reverse domain produced by pulsing conductor M by monopulser 14. Each pair of domains in a digit position are then propagated along a domain wire selected by one of the number select switches 1 to 50, Fig. 3, by propagation conductors P1 and P2K pulsed in a four phase manner by FORWARD pulse source 12, the separation between domains in a digit position remaining constant. Each coded pair is advanced seven positions in a selected domain wall wire as soon as it is stored, the domains not moving along nonselected domain wires and next succeeding domains are written into all the wires regardless of the presence of domains fron a preceding digit write operation. When the marker domain DM reaches forward position conductor 18 a current is produced therein which causes the information to cease advancing and remain in the storage position of the wire. Initially sense conductor 15 is inhibited when information is first moved from a write portion to a storage portion but normally has a pulse induced therein if a domain passes from left to write. In order to read a selected number from a selected wire the subscriber goes off-hook and depresses a number-select button corresponding to one of the switches No. 1-50 which connects the propagation conductor of the selected domain wall wire to the backward propagation pulse source 13. Information is shifted backwards until a reverse domain arrives at the backward position conductor 19 inducing a bipolar pulse pair therein, the first pulse of the pair causing the pulse source 13 to be inhibited and the propagation to cease. The second pulse of the pair causes forward pulse source 12 to be triggered and the information to be stepped from left to right. When the marker pulse DM reaches the sense conductor 15, which is now enabled, the pulse induced therein sets a seven gate converter 48 and resets a sevenstorage stepping switch 47. The next four phase propagation sequence advances the first bit of information past the sense conductor 15 and if there is no reverse domain in the position advanced past the sense conductor no pulse is induced therein and the first position of the seven gate converter 48 stores a binary zero. If the next four phase propagation sequence advances a domain past the sense conductor 15 a binary one is stored in the second position of the converter 48. When seven bits are stored in the seven positions of the converter stepping switch 47 provides a readout signal to converter 48 to provide a parallel readout. The readout process continues until the marker domain arrives at the forward position conductor 18 when the pulse induced therein results in forward pulse source 12 being inhibited and the propagation terminated.

[Also in Division H3] A character recognition arrangement comprises a magnetic domain wall device, means for storing an input character therein as a pattern of stable magnetic domains, means for producing a coded magnetic field pattern in the device, and means for indicating correlation, if any, between the domain pattern and the coded magnetic field pattern. A magnetic "domain wall" wire is initially magnetized all in one direction by a bias field. Each bit of an input character is applied to nucleate or not (depending on the bit value) a reverse-magnetized domain at one end of the wire, the domains being shifted along the wire in synchronism with bit arrival by a 4-phase system of pulses on two wires. Every bit time, a pulse is applied to an interrogate winding coupled to each bit position in the wire in a sense corresponding to the value of the corresponding bit of the character to be recognized. This pulse momentarily attempts to set the bit positions to correspond to the character to be recognized and only if the input character (when fully in the wire) is equal to the character to be recognized will no appreciable change in magnetization be produced and therefore no signal in a sense winding coupled to each bit position in the same sense as the interrogate winding. The wire could be replaced by a magnetic thin film device. The character to be recognized could be preselected by punching a printed circuit board having alternate wiring paths.

1,126,340. Data stores. SPERRY RAND CORP. 10 Dec., 1965 [21 Dec., 1964], No. 52548/65. Heading G4C. [Also in Division H3] In a magnetic memory comprising an array of magnetic storage elements and associated groups of drive wires word organized whole blocks of words are re-recorded every time that new information is written in any one memory address of a group by means of shift registers. In the arrangement of Fig. 2, a plurality of wires 21-32 coated with uniaxial anisotropy magnetic material are arranged horizontally and drive lines I 1 1, I 2 1, I 3 1, I 4 1 &c., are placed orthogonally to the coated wires to define the words in groups I, II, each intersection constituting a bit of a memory word. In order to store information in a particular bit position the required drive line is energized by means of the selected driver 40 and simultaneously applying a positive or negative steering current to the selected plated wire 21-32 from digit driver 20. Read out is effected by energizing the appropriate drive line so that a signal is induced in the wires 21-32 and detected by sense amplifier and storage register 43. After each word is read out the same information is re-recorded by causing the digit drivers 20 to be energized and at the same time energizing the required drive line. Information is thus rerecorded in all address locations whenever any one address has new information recorded; thus preventing creep into adjacent bits. By including a gap between word groups I, II creep is prevented along the wires. In a second embodiment, Fig. 1 (not shown), a coated wire has a plurality of drive lines positioned orthogonal thereto each intersection comprising a bit position and a plurality of words being formed along one plated wire. Each word along the same wire is separated by a distance greater than the distance between the respective drive lines of a particular word. When new information is recorded into a bit of a word all the adjacent bits are re-recorded by sequentially energizing the drive lines of the word thus preventing creep.

1,158,182. Domain stores. WESTERN ELECTRIC CO. Inc. 29 Nov., 1966 [30 Nov., 1965], No. 53383/66. Heading G4C. [Also in Divisions H3 and H4] In a storage device comprising a magnetic medium through which data in the form of locally reversed magnetic domains is propagated, provision is made to reverse the direction of propagation when the first domain reaches the output end, if a utilization circuit is not ready to receive the output. As shown, multifrequency signals from a subscriber's pushbutton telephone are converted at 20 into pulses on 2 out of 7 lines a to #. Each pair of pulses energizes a corresponding line pair such as 19C, which coact with a strobing pulse on a line 17 to locally reverse the direction of magnetization of a domain in a wire 12. Further strobing pulses operate a driver 15 pulsing a winding 16, causing the reversed domain to shift to the right. At each shift the driver reverses a domain in a second wire 11 and shifts any previously reversed domains in that wire to the right. When the reversed domain in the wire 12 passes the coil 14 it sends a pulse to the driver inhibiting reversal of further domains in the wire 11. Thus the number of reversed domains is equal to the number of shifts required to bring the reversed domain in the wire 12 to the coil 14, and corresponds to the selected digit. The reversed domans are read out from the wires 11 and 12 at 40a and 40b respectively when required and represent the correct number of dialling pulses for a digit and an interdigit spacing respectively. Where a reversed domain is read out it sets an output busy trigger 34 which enables an AND gate 51, so that the next domain is detected by windings 44 and operates a driver 16 to cause the direction of shifting to reverse. Reverse shifting continues until a reversed domain reaches the input position or until a new clock cycle is initiated, at which point forward stepping is again initiated. Trigger 34 is reset periodically after sufficient delay to ensure the utilization circuit is ready to receive the next pulse. A circuit enables an AND gate 46 for a predetermined longer period to effect the required interdigit spacing.

1,141,903. Magnetic storage arrangements; automatic exchange systems. WESTERN ELECTRIC CO. Inc. 26 May, 1966 [15 June, 1965], No. 23535/66. Headings H3B and H4K. A calling line identification arrangement comprises first and second shift registers SR1, SR2, Fig. 1, of the movable domain wall type, with each subscriber's line L1, L2 ... connected to a different scan position in the first register SR1, those lines which are in the offhook condition establishing a reversed domain pattern which is propagated periodically by multiphase advance clock driver 33 through both registers in turn. A domain reversed by off hook current appears at lines 22 and 24 in turn during a shift cycle, its time position denoting the scan position and thus the line identity. No domains are propagated when all lines are on-hook. In operation, a line newly off-hook is identified by a pulse in line 22 alone when the domain reaches the end of shift register SR1 during the shift cycle immediately following, while continuance of the off-hook condition during subsequent cycles is denoted by the simultaneous appearance of pulses in lines 22 and 24. When a subscriber's line goes on-hook the new condition is denoted in the shift cycle immediately following by a pulse on line 24 alone. The newly off-hook or on-hook conditions of a line are identified by a circuit comprising exclusive OR gate 20 and AND gates 21, 23, 27, 28, each condition causing a central processor 12 to appropriately control a switching matrix 11. Each register may comprise a respective wire of ferromagnetic material having a rectangular hysteresis characteristic, or may comprise a single wire of such material with an intermediate sense coil connected to line 22. The magnetic wire 100, Fig. 2, is is coupled at spaced positions by coils connected to respective lines 1, 2 ... and is also coupled at these spaced positions by a common coil 101 connected to a nucleation driver 14, Fig. 1. When a line is in the off-hook condition, e.g. line 2, the line current is insufficient by itself to establish a reversed domain, but such a domain is established when a periodic pulse is received from the nucleation driver. A bias may additionally be used. In a modification, Fig. 5, each line La-Ld is coupled to a separate magnetic wire 100a-100d, each of a different length, so that pulses are induced in a common sense winding S, in turn, when the reversed domains established by off-hook lines are advanced by a multiphase advance clock driver 133 to the end of the register. In this arrangement the nucleation driver establishes a reversed domain in each magnetic wire by applying a periodic pulse to coil N, and domains associated with off-hook lines La-Ld are expanded by the offhook currents. Only expanded domains are propagated by the multiphase advance pulses applied to coils P2, P1 from advance clock driver 133, the stationary domains at the onhook positions being erased by a reset pulse in coil R from a reset driver 215.

1,130,198. Magnetics shift registers. UNITED STATES ATOMIC ENERGY COMMISSION. 26 Oct., 1966,[16 Nov., 1965], No. 47955/66. Heading H3B. [Also in Division H1] The input element of a magnetic counter or shift register fusing the moving magnetic domain principle is movable so that information can be written at a selected region of the storage medium. As shown the storage medium is a nickel-iron wire 10 wound spirally on a cylindrical substrate 40 and shift conductors 28, 30 connected to a two-phase clock are arranged in a meandering configuration around the substrate, so that they extend generally axially of the cylinder. The inner surface of the substrate 40 is provided with a spiral groove 44 corresponding in lead and pitch to the wire spiral 10, and a stem 48, again with the same lead and pitch, is provided on the axis of the cylinder A beryllium copper spring 50 surrounds the stem. Threaded on stem 48 is a write head assembly 61 carrying a nucleation coil 20 on a ferrite core, the core and coil extending into groove 44. The head assembly 61 also carries, in a pair of diametrically opposed slots, two toroidal cores (Fig. 6, not shown) having secondary windings connected in series with the nucleation coil 20. Two turns of spring 50 pass. through the apertures of the cores and form a primary winding for each core, energized from input source 18. The write head is rotated by shaft 96 attached to a knob 90, the thread on stem 48 causing the head to track along groove 44 as it is rotated. Data entered at a selected region eventually reaches output coil 22 wound round storage wire 10. Coil 24 is a bucking coil not wound round wire 10 and compensating for the effect of the shift conductors 28, 30. Since the currents in the shift conductors 28, 30 are favourable for entering data only once in each cycle the write head must always be moved to the same position relative to the shift conductors, i.e. if the input source is synchronized with the shift pulses for entering datawhen the headis adjacent a portion of conductor 28 in which current flows upwards then writing can only be accomplished adjacent such conductor portions. An index on knob 90 isco ordinated witha dial plate and calibrated to indicate the allowed positions and the count corresponding to each position. By moving the writing head the count required between data being entered and read can be varied. The time taken for a given count to be reached may be varied by changing the frequency ofthe shift pulses. An additional reading coil may be provided at the opposite end of wire 10 to determine the complement of the count determined by coil 22. Bias permanent magnets may be arranged at each end of wire 10 to keep it uniformly magnetized.

In a repertory dialler a memory comprises a plurality of magnetic domain wall wires in which information is written into a write portion of all the wires simultaneously but is moved along only a selected wire for read out and storage. The dialler includes a magnetic domain wall wire DW for each telephone number stored, only one being shown in Fig. 1 and seven input conductors L1 to L4 and H1 to H3 are coupled to all the domain wall wires, Fig. 2 (not shown), the depression of a a digit select button in the push-button array of a subscriber's V.F. sender, Fig. 6 (not shown), corresponding to the actuation of a coded pair of the seven conductors. Thus a telephone number is stored as a plurality of coded reverse domain pairs by pulsing two of the input conductors. The two reverse domains of the first digit are preceded by a marker reverse domain produced by pulsing conductor M by monopulser 14. Each pair of domains in a digit position are then propagated along a domain wire selected by one of the number select switches 1 to 50, Fig. 3, by propagation conductors P1 and P2K pulsed in a four phase manner by FORWARD pulse source 12, the separation between domains in a digit position remaining constant. Each coded pair is advanced seven positions in a selected domain wall wire as soon as it is stored, the domains not moving along nonselected domain wires and next succeeding domains are written into all the wires regardless of the presence of domains fron a preceding digit write operation. When the marker domain DM reaches forward position conductor 18 a current is produced therein which causes the information to cease advancing and remain in the storage position of the wire. Initially sense conductor 15 is inhibited when information is first moved from a write portion to a storage portion but normally has a pulse induced therein if a domain passes from left to write. In order to read a selected number from a selected wire the subscriber goes off-hook and depresses a number-select button corresponding to one of the switches No. 1-50 which connects the propagation conductor of the selected domain wall wire to the backward propagation pulse source 13. Information is shifted backwards until a reverse domain arrives at the backward position conductor 19 inducing a bipolar pulse pair therein, the first pulse of the pair causing the pulse source 13 to be inhibited and the propagation to cease. The second pulse of the pair causes forward pulse source 12 to be triggered and the information to be stepped from left to right. When the marker pulse DM reaches the sense conductor 15, which is now enabled, the pulse induced therein sets a seven gate converter 48 and resets a sevenstorage stepping switch 47. The next four phase propagation sequence advances the first bit of information past the sense conductor 15 and if there is no reverse domain in the position advanced past the sense conductor no pulse is induced therein and the first position of the seven gate converter 48 stores a binary zero. If the next four phase propagation sequence advances a domain past the sense conductor 15 a binary one is stored in the second position of the converter 48. When seven bits are stored in the seven positions of the converter stepping switch 47 provides a readout signal to converter 48 to provide a parallel readout. The readout process continues until the marker domain arrives at the forward position conductor 18 when the pulse induced therein results in forward pulse source 12 being inhibited and the propagation terminated.
