Magnetic bubble data transfer switch

A magnetic arrangement which permits the synchronized interchange of magnetic bubble domains between two magnetic propagation paths,

• first and second paths for defining and controlling the movement of magnetic bubble domains in response to cyclic magnetic field stimulus,
• first and second ports for selectively interconnecting said first and second paths in response to control signals and transferring bubble domains between said first and second paths,
• first and second conductor means associated with said first and second ports, respectively, for providing said control signals,
• means for supplying first and second control signals to said first and second conductors, respectively, during one cycle of said cyclic magnetic field, and
• a timing adjustment member associated with at least one of said first and second ports for adjusting the transfer of bubble domains between said first and second paths in order to maintain synchronism of bubble domain movement in both of said first and second paths concurrently.
