1,181,091. Magnetic storage devices; exchange systems. WESTERN ELECTRIC CO. Inc. 21 Feb., 1967 [4 March, 1966], No. 8177/67. Headings H3B and H4K. Multifrequency input information from a subscriber is converted into dial pulses by changing each digit of the input, in turn, into a one-out-of-ten code, this code being entered into a write portion 12 of a magnetic domain wall device by reversing the magnetic direction of two adjacent reference positions and by reversing at the same time a third position spaced from the reference positions in accordance with the value of the input digit. Each digit when recorded is moved along the wire into a buffer portion 13, and when a " digit accept " signal is received, the digit is transferred to a read-out portion 14, transfer of a digit from the buffer to the read-out portion taking precedence over transfer from the write to the buffer portion. The domain wall device may comprise a magnetic wire 11 with reference positions established in the write portion 12 by energizing coils CR, the magnetized reference positions transferred to the buffer and read portions 13, 14 being located by coils 30, 31 and 62, 63 respectively. The digit wires C1 . . . C7 . . . C0 from a multifrequency to one-out-of-ten translator T are connected to respective coils (not shown) spaced along the write portion of the wire. The reversed magnetization positions are stepped from the write to the buffer portion by energization of two parallel groups of coils 16 from a 4-phase write pulser 18, and are stepped from the buffer to the read portion by 4-phase energization of similar coils 53 from a read pulser 51. The write pulser 18 becomes operative, as soon as a digit is recorded, through a differentiator 21, a set bi-stable circuit 22, a short duration delay A and a set bi-stable circuit 25, the AND gate 23 in the path being open when a bi-stable circuit 45 is in the reset state and a positive clock pulse is obtained from a source 43. When the reference positions of a recorded digit are detected in the buffer portion by coils 30, 31, bi-stable circuits 22 and 25 are reset and digit movement along the wire ceases. Reading is started by applying a " digit accept" pulse to terminal 40 which sets bi-stable circuit 41, and so enables bi-stable circuit 45 to set over an AND gate 42 when a negative clock pulse is received from source 43. Read pulser 51 is then operative and moves the digit stored from the buffer portion into the read portion. A bi-stable circuit 60 is set when the digit reference positions are detected in the read portion by coils 62, 63, and the clock pulses from source 43 are enabled to pass to the output through AND gate 66. The clock output pulses constitute the dial pulses required and are in time with the stepping movement of the recorded digit along the wire 11. When the third reversed magnetization position, representing the digit value, is detected by a coil 61, the bi-stable circuit 60 is reset and the dial pulse output terminates. Consequent upon each output pulse, bi-stable circuit 45 is temporarily reset over OR gate 70, until the next clock pulse is received so as to permit a further digit to advance from the write to the buffer portion. Resetting of bi-stable circuit 60 causes bi-stable circuit 41 to be reset over a differentiator 72 and OR gate 77. A monopulser M is provided for transmitting a resetting pulse to bi-stable circuit 45, so permitting digit writing if a " digit accept " signal is received when the domain wire is clear of information. An interdigit spacing circuit 74 is operative until disabled by a pulse from differentiator 72.

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.

951,860. Magnetic storage devices. HUGHES AIRCRAFT CO. June 12, 1962 [July 28, 1961], No. 22511/62. Heading H1T. [Also in Divisions G4 and H3] Two adjacent domains of opposite polarity with the common boundary wall in a neutral position are established in part of a magnetic wire, the wall being moved in one or the other direction to record binary information, and restored to its neutral position for reading out the information stored. As shown in Fig. 1, a magnetic wire 10 is continuously magnetized by domain forming windings 12, 14 to establish opposing fluxes 103, 105 having a boundary wall in a neutral position 32. This wall is moved in one or the other direction when current is passed through a control or digit winding 46, depending on the current direction and hence the digit value to be recorded. To read out the digit stored, reading windings 24, 26 are energized and produce opposing magnetic fluxes 100, 101 sufficient to restore the boundary wall to the neutral position. As a result an output voltage having a polarity determined by the direction of movement of the boundary wall is induced in the control winding 46. To prevent information stored from being influenced by further pulses through the control winding, as occurs in an array of storage units, the displaced boundary wall is held in position by continuously energized detent windings 34, 36 producing fields 85, 87 in opposition to the adjacent domain magnetizations 103, 105. Each operating cycle is effected by a clock 67 producing spaced pulses C 1 and C 2 , the pulse C 1 initiating a read operation by energizing a read pulse generator 27 so that the boundary wall is restored to the neutral position. The induced output in the control winding 46 is applied by way of a transformer 49 to a sense amplifier 52, and if a binary one is read out, a pulse is passed to an output AND gate 54 at the same time as a stroke pulse obtained from the read pulse generator over a delay 56 and differentiating circuit 59 is applied to the gate. Writing takes place when clock pulse C 2 is applied to a write pulse source, the control winding 46 then being appropriately energized depending on the digit to be stored. A nickel iron alloy wire 10 is used which may be maintained under tension. Several digits may be stored along a single wire, the principle being shown in Fig. 6 in which the limits of a first storage element are defined by domain forming coils 164, 166 and the second storage element limits by domain forming coils 166, 168, the shared coil 166 necessitating a pattern of opposing domain magnetizations 397, 405 and 405, 413 which alternate in sense in successive elements. Such an arrangement having two storage elements for each magnetic wire 142, 142a ... is shown in Figs. 5 and 5a. A two bit word is stored in each magnetic wire and is selectively read out by applying a positive pulse from a read pulse generator 214 to a column address driver 242 or 248 and a negative pulse to a row address driver 222 or 234. The combined pulses in the selected read windings 138, 140, 150, 152 are sufficient to switch the boundary walls in a single wire to the neutral position and so induce bits outputs in respective control windings 160, 162. These outputs are applied over transformers 206, 212 to gating circuits 272, 318 each comprising a transistor amplifier 270, transformer 280 and an output AND gate the other input of which is obtained from a strobe circuit 296. Each gating circuit also includes a checking arrangement comprising an inhibit gate 310 controlled by the strobe pulses which operates an error flip-flop 314 if no output from transformer 284 is detected in any strobe period. Positive or negative inputs from pulse forming circuits 330, 360 are applied to the transformers 206, 212 to write a word into the magnetic wire previously read out, the input pulses being applied to the upper and lower control windings 160, 162, respectively, of all the magnetic wires. Since the magnetizations of all the wires already recording a word is sustained by the detent windings 170, 172, 176, 178, the reading and writing currents have not effect on the wire magnetizations. Thus only the boundary walls in the previously read out wire are moved to recording positions. The pulse forming circuits 330, 360 each coil comprises a flip-flop 334 which is set to a first state if outputs from either of AND gates 336, 337 are received by way of OR gate 335, and is set to a second state if a differentiated pulse from a write pulse generator 326 is the only signal received. If a read out word is to be rewritten, a pulse is applied from lead 339 to the AND gate 336 in coincidence with a signal on lead 338 derived from the gating circuit output leads 300, 324. If new information is to be entered, this is applied to lead 341 in coincidence with a control signal in lead 340. The write pulse generator 326 is controlled from clock source 220 and energizes flip-flop output transistors 342, 343, the first or second state of the flip flop respectively causing a positive or negative writing pulse to be applied to a transformer 208, 212 by way of transistors 345 and 350 or transistor 355. The detent coils are omitted from the embodiment shown in Fig. 7 which is also modified by the use of transistor address drivers 536, 550, 512, 526 The detent action is provided by a continuous bias in the reading windings 430, 432, 434, 436 which is reversed in polarity only when a selected wire is subjected to a reading pulse by energizing a row and a column transistor. Constructional details are also disclosed in which each magnetic wire 628, 690, 694, 698, Fig. 10, has a control or digit winding 646, 666, 674, 684 extending the whole length of the wire, and common overlaid domain forming windings 700, 725, 739 and read windings 708, 710, 736, 738. The overlaid windings may be formed by a weaving technique in which a shuttle carrying insulated wire is passed between the parallel magnetic wires. The position of the detent coils, if provided, is shown by broken line 792 for one bit position. When weaving is completed, the magnetic wires are bent at spaced intervals in alternate directions so as to form a compact plated assembly. The various windings are then interconnected. It is stated that the detent and domain forming windings may be replaced by permanent magnets.

1284023 Magnetic storage devices LICENTIA PATENT - VERWALTUNGS - GmbH 13 March 1970 [14 March 1969] 12236/70 Heading H3B A woven memory matrix has anodized aluminium or aluminium alloy drive wires as the warp and weft. The wires may be anodized before or after weaving, and in either case the anodized layer insulates the wires from one another. The layer is rendered hole free by heating in steam and then the woven matrix is dipped in a molten resin or glass adhesive. The excess adhesive is removed in a centrifuge, and the stable matrix thus produced is plated with gold or copper by a vapour deposition or an electroless process. A nickel-iron magnetic film is then electrodeposited on to the plated layer, while a current is passed through the warp or weft to establish an easy axis of magnetization. To prevent interaction between adjacent storage sites, the film and the gold or copper layer is etched away to leave magnetic material only adjacent the wire cross points. Alternatively, the gold or copper may be deposited only at the cross points. A magnesium-aluminium alloy having 1-5% Mg is preferable.

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.

1,271,540. Magnetic storage arrangements. COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE. 24 Dec., 1969 [30 Dec., 1968], No. 62831/69. Heading H3B. A magnetic storage element comprises a helical path 10, Fig. 4, of thin film material whose easy axis of magnetization K lies in the film normal to the longitudinal axis of the helix. Bits are stored in the path as areas of reversed magnetization, and are written in by pulsing a conductor 18. The bits are propagated from a continuous ring 16 of film adjacent conductor 18 by a rotating magnetic field H, and may be read out by detecting pulses induced in a conductor 19 adjacent a second ring of film 17. The bits may be held stationary by passing an alternating current through a conductor adjacent the helix, this conductor either lying as shown at 20 or passing axially through the carrier body 13 around which the helix is wound. A D.C. bias may also be applied on these conductors. Two helices of opposite thread may be joined in parallel by anisotropic magnetic bridges which couple their end rings together, Fig. 6 (not shown), so that stored bits circulate continuously in the pair. Alternatively the helices may be wound on a common carrier body, Fig. 7 (not shown). Several elements may be arranged to form a store, Figs. 10, 11 (not shown), in which selection is achieved by inhibiting propagation in all but the desired element. Information may be rewritten after reading in the Fig. 10 embodiment. The element shown in Fig. 12 has additional conductors 41-44. Pulses may be applied to these conductors to convert an adjacent "1" into a "0". Conductors 41, 42 control writing, and conduc- 43, 44 control read out. Fig. 13 shows an arrangement of such conductors to form a store in which 4n elements are connected to form four Groups I-IV. Each input conductor 18 (or a) is coupled to one element in each group, while each control conductor 41-44 (or b-e) is coupled to all the elements in two groups. Each control conductor is also connected to one terminal of a bi-stable circuit B-E, and those circuits may be activated in such a way that only one of the groups at a time has both its writing control conductors in a state to allow a "1" to propagate. For example, if B gives an output at the terminal marked +, then group I is selected by an output from C + while group II would be selected by C-. Reading is similarly controlled, and simultaneous writing and reading may be achieved. In all the above elements, the alternating current may be used to erase stored bits by raising its amplitude.
