    Abstract: 1487121 Shift registers INTERNATIONAL BUSINESS MACHINES CORP 1 May 1975 [14 May 1974] 18157/75 Heading G4C To edit a text, a shift register storing a line of data bits representing text has a normal path 34 (Fig. 2A) and a by-pass path 36 so that the order of the bits may be changed, gaps in the data may be closed and data bits may be deleted. The shift register may be either a medium capable of supporting magnetic bubble domains in which case drive pulses for the register in the form of an unchanged repetitive sequence of drive pulses are provided by a rotating magnetic field or a charge coupled device in which case three phase propagation lines receive successive signals. As described the normal path includes a freeze and input/output position at which new data may be written by a write circuit (48, Fig. 2B, not shown), annihilated (in the case of the bubble domain embodiment by passing a large current through freeze loop (46)) or held whilst other data is shifted round the by-pass loop. The editing shift register (24, Fig. 1, not shown) is connected between the read decoder output from and the write decoder input to a plurality of shift registers (SR1-SRn) used for storing data text. A spare shift register (SR) is provided so that the contents of the shift registers may be interchanged.

    Abstract: 1,250,085. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 13 Nov., 1969 [16 Dec., 1968], No. 55562/69. Heading H3B. In a magnetic storage arrangement, a storage location defined by the crossing point of orthogonal conductors 3, 7, comprises a number of thin, magnetically anisotropic films 2, 4, Fig. 1, having different critical switching fields H K , so that by applying a particular sequence of pulses to the conductors each film may be made to store a different bit of a word. In Fig. 1, the films are separated by a non-magnetic material 5, which may be electrically conducting, and each of films 2 is magnetically coupled to a correspondingly disposed and magnetically similar one of films 4. Alternatively, Fig. 4, the films 4 may be replaced by a single film 8 whose cross-sectional area equals the total cross-sectional area of films 2. The magnetic flux paths around the films and conductors may be closed by keepers 15, 16. To write into the structure of Fig. 4, a pulse 17, Fig. 6A, of sufficient magnitude to switch all three films 12, 13 and 14 to the hard direction is applied to word conductor 3, overlapping with a pulse 18 on conductor 7 which establishes a tipping field along the easy axis. When pulse 17 is terminated, the three films have a common direction of magnetization along the easy axis which represents a " 0 " or a " 1 " depending on the polarity of pulse 18. The operation is repeated, using a pulse 19 of such lesser magnitude that only the two most easily switched films are affected, the tipping pulse 20 being shown with a polarity opposite to that of pulse 18. To write into the third film, a smaller pulse 21 is applied on conductor 3, with a coincident pulse 22 on conductor 7. Reading is carried out by reversing the pulse sequence in conductor 3, giving output pulses 26, 27 and 28 in conductor 7. The operations may be speeded up by using a descending or ascending staircase waveform in place of the discrete writing or reading pulses of Fig. 6A, as in Fig. 6B (not shown). A method of making the storage locations in multiple by vapour deposition is described, the films of least H K lying furthest from conductor 3. The films are of Permalloy, and the variation of H K is achieved by choice of cobalt concentration. The films may have different widths, Fig. 3 (not shown).

    Abstract: 1437014 Moving domain systems INTERNATIONAL BUSINESS MACHINES CORP 15 June 1973 [22 June 1972] 28631/73 Heading H3B In a bubble domain system the fields applied to a bubble domain device are too small to cause propagation or collapse unless a controlling in-plane bias field is applied. In Fig. 4 strip lines X1, X2, Y1 and Y2 overlie bubble device 10 and may be activated in pairs to provide an in-plane bias field. The device 10 has an angel-fish propagation pattern 18, though any other propagation system may be used; the field source 12 provides a varying bias field normal to the device as is conventional when angel-fish are used, but this bias field variation is such that a domain oscillates between two adjacent angle-fish and does not propagate. It is found that when an in-plane field is applied by coincident operation of an X strip line and a Y strip line the domain mobility is increased and propagation occurs. The use of an in-plane control field also allows other functions such as annihilation to be similarly controlled; a presence/absence bubble domain system in which bubbles are only generated and collapsed, without being propagated, can also be controlled, Fig. 6 (not shown). The in-plane control may be used with any bubble domain material, the minimum in-plane field being when the field is perpendicular to the propagation direction and being given by the expression where h is the thickness of the material and A is its exchange coefficient.
