Abstract: Features for loading, transporting and unloading of items are disclosed. Systems, devices and methods for such operations using a tray are described. In some embodiments, a tray having a moveable bottom allows for switching between a configuration for loading and unloading items in and out of the tray and a configuration for transportation of items inside the tray. The trays may also be stacked, for transportation of multiple trays at once, and nested, for saving space when storing the trays. In some embodiments, the trays may be used in conjunction with loading and unloading systems.

Abstract: Two-way disc mailers for mailing DVDs, CDs, video game discs, or other discs from a sender to a recipient via first class mail. The disc mailer provides improved automated mail processing while weighing less than or equal to 1 ounce, including the weight of the disc.

Abstract: Described herein is a system and device for singulating mail pieces during mail processing and sorting. A double inhibit mechanism, mounted opposite a feed belt assembly and having at least two degrees of freedom at its downstream end, can maintain contact with mail in the mail path while separating overlapping mail pieces and allowing only single pieces to pass thereby.

Abstract: A diverter gate generally includes a bracket which connects to an actuator and a flag which releasably engages with the bracket via cooperating engagement members. The cooperating engagement members may be symmetrical, and may comprise one or more tabs and one or more corresponding receptacles. The tabs may be dimensioned slightly larger than the receptacles so as to create a positive interference fit. The bracket and the flag may include openings to receive a fastener extending substantially across the length of the gate. Tightening the fastener compresses the tab(s) against the receptacle(s) to result in a compression fit between the flag and the bracket. The two-piece design allows the flag to be easily removed and reversed or replaced, without disassembling or removing the bracket or the actuator.

Abstract: A one and two-way disc mailer for mailing DVDs, CDs, video game discs, or other discs from a sender to a recipient via first class mail. The disc mailer provides improved protection to the disc during mail processing while weighing less than or equal to 1 ounce, including the weight of the disc, for first-class compatibility.

Abstract: An improved process is provided for selectively synthesizing pyridine and 3-alkylpyridine in high yield by reacting ammonia and a carbonyl reactant selected from the group consisting of formaldehyde, an aldehyde containing from 2 to 4 carbon atoms, a ketone containing from 3 to 5 carbon atoms, and mixtures thereof under effective conditions in the presence of a catalyst comprising an active form of a synthetic porous crystalline MCM-49 or synthetic porous crystalline material characterized by an X-ray diffraction pattern including interplanar d-spacings at 12.36.+-.0.4, 11.03.+-.0.2, 8.83.+-.0.14, 6.18.+-.0.12, 6.00.+-.0.10, 4.06.+-.0.07, 3.91.+-.0.07, and 3.42.+-.0.06 Angstroms, e.g., MCM-22, and recovering from the resulting reaction mixture a product enriched in pyridine and 3-alkylpyridine.
