  • Field-accessed magnetic bubble mutually exclusive circuits with common elements
    Patent number: 4096582
    Abstract: Composite mutually exclusive field-accessed circuit elements common to a plurality of bubble paths. A channel composed of mutually exclusive circuit elements is linked to an adjacent parallel channel of mutually exclusive circuit elements by means of circuit element portions common to both channels. The interconnected channels are operated mutually exclusively by means of corresponding pulsed field sequences. Transfer between the linked channels is via the common circuit element portion. Several new types of propagation circuits are also discussed along with organizations for mutually exclusive major and minor closed loops featuring controlled transfer via common circuit element portions.
