Abstract
1452934 Magnetic storage arrangements MONSANTO CO 29 Nov 1973 [1 Dec 1972] 52323/75 Heading H3B A magnetic bubble replicator includes means to provide simultaneously a number of replica bubbles corresponding to an input bubble, and means to provide the replica bubbles in serial form on an output path. Replica bubbles on paths 120, 124 pass to annihilators 136, 138 unless there is a bubble on input path 122. In the latter case the replica bubbles are transferred via fields 132, 143 to paths 126, 130. Delays 140, 142 cause the replica bubbles and the bubble from path 122 to appear in sequence on output path 144.
