A process includes coding or marking a first side of a ream of paper such that a first mark appears on an edge of each sheet of paper of the ream of paper. This coding or marking results in the first mark absorbing onto a top surface and a bottom surface of each sheet of paper of the ream of paper. The coding or marking can either convey information or serve a function such as assisting in folding a sheet of paper.

The present disclosure provides flow cells and methods of fabricating flow cells. The method includes combining three portions: a first substrate, a second substrate, and microfluidic channels between the first substrate and the second substrate having walls of a photoresist dry film. Through-holes for inlet and outlet are formed in the first substrate or the second substrate. Patterned capture sites are stamped on the first substrate and the second substrate by a nanoimprint lithography process. In other embodiments, parts of the patterned capture sites are selectively attached to a surface chemistry pattern formed of silicon oxide islands each disposed on an outcrop of a soft bottom layer.

A conveyor system is provided including a conveyor and a plurality of functional trays that are removably attachable to the conveyor. Each tray includes a plate having first and second dimensions that are orthogonal to each other, and the plate includes a coupler configured to be removably attached to the conveyor with the second dimension of the plate being in parallel with a moving direction of the conveyor. The plurality of functional trays include one or more of an envelope-opening mechanism, an item-pushing mechanism, an envelope-closing mechanism, an item-wrapping mechanism, and a tray-height-adjustment mechanism. For example, the item-pushing mechanism includes a pusher slidably coupled to the plate, and a linear actuator configured to move the pusher relative to the plate along the first dimension so as to push an item off the functional tray.

A method for opening an envelope throat of an envelope transported along an envelope channel dependably opens the envelope throat of the envelope during insertion in an inserter. The envelope, in order to open the envelope throat, is first over-pressed against a counter-pressure and then the counter-pressure is released to open the envelope throat, and/or the envelope is over-pressed against the hold-down force that holds the envelope down on an envelope transport, in order to open the envelope throat. For this purpose, an inserter inserts one or more items into an envelope moving along an envelope channel.

In one embodiment, a surface having a sealing groove formed therein. The sealing groove is configured to accept an elastomeric seal. The sealing groove includes a first portion having a full dovetail profile and at least on a second portion having a half dovetail profile.

An automated greeting card conveyance system is disclosed that includes a first conveyor configured to transport pre-decorated greeting cards along a first conveyance path and a second conveyor configured to transport envelopes along a second conveyance path. A control system controls customization of each greeting card and envelope by (a) determining a card identifier of the greeting card, (b) identifying customized content associated with an order for the greeting card having the card identifier, and (c) causing the customized content to be printed on the greeting card and envelope. A coupling system may also be used to automatically insert the greeting card into the envelope. In addition, a sealing system may be used to automatically seal envelope having a pointed envelope flap.

The present invention provides automated systems and methods of affixing tray tag labels to mail trays in an automated fashion. The systems and methods of the present invention provide an economic, cost-efficient, and reliable means of affixing tag labels to mail trays.
