Abstract: A passive bubble replicator is achieved by adding to a stage of a multistage, fine-grained, field-access bubble propagate circuit, magnetic elements of a geometry to provide laterally spaced localized attracting poles and a repelling intermediate pole in the propagation path. Normal operation of the finegrained propagate circuit provides poles which first expand a bubble laterally and thereafter cooperate with the intermediate pole to cut the expanded bubble.

Abstract translation: 设置在参考台和下一个后续阶段之间，以响应于平面内场来提供两个横向间隔开的强吸引极和中间排斥极。 当场重新定向到该阶段的剩余（人字形）元件的方向表现出排斥极的方向时，提供这些极点，以将区域推进到下一个后续阶段。 结果是在那里存在横向细长气泡的分叉，从而提供两个局部气泡，用于沿着输出通道的前进。 完全被动的操作，仅响应于传播驱动（平面）场。

Abstract: The displacement of single wall domains in a domain propagation medium is achieved along a straight line conductor to which bipolar pulses are applied. Discrete magnetically soft elements are disposed to respond to the in-plane components of the fields generated by the pulses to produce consecutively offset poles to displace the domain in the desired direction.

Abstract: The transfer of single wall domains between propagation channels defined in ''''field access'''' arrangements by magnetically soft elements adjacent a layer in which the domains can be moved is achieved by a hybrid arrangement of magnetically soft guide elements and a conductor which effects lateral displacement of domains in pairs between fixed positions defined by the guide elements consistent with positions which are part of the channels involved in the transfer.
