Abstract: According to some embodiments a system and an apparatus comprise a registration wall, a weighing device located adjacent to the registration wall, a belt drive mechanism, a plurality of inboard skis, and a plurality of outboard skis. The belt drive mechanism extends across the weighing device for advancing a mail piece relative to the weighing device and the belt drive mechanism is located at a first distance from the registration wall. The plurality of inboard skis are located substantially at the first distance from the registration wall and are located beneath the belt drive mechanism for urging the mail piece upwardly toward the drive belt mechanism. The plurality of outboard skis is coplanar with the plurality of inboard skis for supporting an end of the mail piece. The plurality of outboard skis is located at a second distance from the registration wall. The second distance is greater than the first distance.

Abstract: A contaminant detection system for mail is provided. A tray of mailpieces is transported along a transport path into a chamber that has a negative pressure maintained by a vacuum system. The tray of mail enters the chamber and is quickly decelerated, such as, for example, by hitting a stop. The quick deceleration compresses the mailpieces in the tray, thereby ejecting air, dust and other particles from the mailpieces into the surrounding environment inside of the chamber. The vacuum system draws the ejected air, dust and other particles into a sampling system that monitors for the presence of a possible biohazard. If any type of contaminant is found in the ejected air, dust and other particles, the tray can be held for further investigation of the mailpieces. If no contaminants are detected, the tray is accepted and the mailpieces are further processed.

Abstract: A method for formatting digital data on an optical disk that represents at least two versions of the same program. Data sequences which are unique to each version and data sequences which are common to the two of them are interleaved in a single data stream. In order to achieve seamless play of both versions on a player that is compatible with the disk format but has limited buffer storage, data which would otherwise be common to both versions is placed redundantly in the data sequences which are unique to both versions.

Abstract: A mixer is mechanically self cleaned without using solvents. A housing defines a mixing chamber with a fluid pressurized mixer head rotatably supported within the housing. The mixer head has retractable mixing paddles. A wiper scrubs material from the mixing head and chamber walls as it is advanced through the mixing chamber during cleaning. A nozzle plunger drives material from a mixing chamber nozzle.
