Abstract: An insertion automation apparatus for discs and booklets in disc packages has plural parallel belts for transporting containers through successive stations. A first station is adjacent the belts for unstacking containers. A second station is adjacent the belts for opening the containers. An inspection station adjacent the belts inspects the opened containers. A fourth station adjacent the belts partially inserts booklets in the open containers, has a booklet conveyor for unstacking and moving booklets and an insertion conveyor for partially inserting the booklets in booklet pockets of the containers. A fifth station adjacent the belts has a pusher for pushing booklets fully into the pockets. A sixth disc placement station adjacent the belts has a continuous looped disc carrier arranged transversely to the belts and plural outwardly spaced disc carrier heads facing outward from the looped disc carrier.

Abstract: A video sync control circuit for controlling the stable synchronization of the display of locally generated signals on a TV screen in the presence or in the absence of a received signal which includes a sync signal. The circuit is comprised of apparatus for receiving an video input signal, apparatus for detecting the presence of an input sync signal which is part of the video input signal, and the absence of the sync signal during all or part of a sync interval of the video input signal, apparatus for locally generating a replacement video signal containing a video display which extends over a predetermined time interval, which is in sync with a local clock, apparatus for phase locking the local clock with the input sync signal, and apparatus for switching the input video signal to an output line during time other than during the time interval, and switching the replacement composite video signal to the output line during the time interval.
