Abstract: An apparatus for personalizing and inserting articles for mass distribution, includes an envelope hopper for holding a plurality of envelopes which each carry a unique machine readable code associated with a unique individual. An article hopper holds a plurality of articles for the individuals. A code scanner reads the codes and an envelope feeder moves one envelope at a time to the scanner. The envelopes are conveyed from the scanner in sequence to an inserting station and a printer reacting to the scanner prints personal information on the articles, each corresponding the an individual for whom a code has been read by the scanner. The printed articles are then feed in the same sequence to the inserting station and are inserted into a corresponding envelope.

Abstract: A hinge rotates a cover pivotably connected to a device housing from a closed position to an open position. A shaft is connected to the cover. The shaft and cover have a common axis of rotation. A spring having a top end and a bottom end is affixed at its bottom end to the device housing. A line has a first end connected to the top end of the spring and a second end wound onto the shaft. When the cover is in the closed position, the spring is in an extended state. Upon release of the cover from the closed position, the spring force returns the spring toward a neutral state, thereby unwinding the line from the shaft and causing rotation of the cover to the open position.
