7. The apparatus as set forth claim 6, wherein the controlling means comprises: first means for detecting the termination of the transfer of each of the coincident full-length words from the first storing means; means responsive to the coincidence signals from the determining means for maintaining each of said coincidence signals for a certain time period; means responsive to the first detecting means and the maintaining means for providing translation control signals, and means responsive to the translation control signals from the providing means for enabling the transfer of the translation corresponding to the incident total word into the second indicating means.
