Abstract: Disclosed is a mechanism for shifting the rack of a selection mechanism for a single element printer from one position to another in timed relationship to the translation of a barrel cam which provides the necessary mechanical input to control the amount of rotation of the typehead. The control of the rack shift mechanism is a cam arrangement operated in timed relationship with the translating barrel cam to provide for the shifting of the rack at the beginning of each print cycle, if necessary, and the retaining of the rack in its shifted position at the completion of the cycle. The elimination of the restore operation of the rack provides more time during the cycle to operate the selection mechanism and accomplish printing or conversely provides for a smaller amount of time being required for the necessary functions thereby providing the capability of operating the mechanism at a faster rate.

Abstract: TILT AND ROTATE APPARATUS FOR A DISPLAY MONITOR An apparatus for permitting, and limiting the extent of, tilting and rotating of a display monitor. The apparatus is made up of a top portion and a bottom portion. The top and bottom portions are connectable though a key and lock arrangement and have spherical mating contoured surfaces. The mating contoured surfaces permit the tilting and rotating of the monitor. Located on the bottom portion is a projection for engaging the top portion and limiting the extent of rotation of the monitor. The key and lock arrangement includes a lock in the bottom portion for cooperating with a key on the top portion to control the extent of tilting of the monitor. In addition, the top portion has outwardly and downwardly extending wings for limiting vibration of the monitor. AT9-79-030
