Abstract: An example of a flow cell includes a substrate; a first primer set attached to a first region on the substrate, the first primer set including an un-cleavable first primer and a cleavable second primer; and a second primer set attached to a second region on the substrate, the second primer set including a cleavable first primer and an un-cleavable second primer.

Abstract: A shipping container made of two panels each made of recyclable, single face corrugated paper comprising an outer liner with corrugated medium. In one embodiment, the panels are formed from a large blank, that is folded in half and joined at their side edges. The flutes on the corrugated mediums are parallel and longitudinally aligned with the shipping container's longitudinal axis. The top edge of each panel is detached and form a top opening into an interior pocket formed between the two panels. Formed or attach to one panel is a top flap configured to be folded over and selectively attached to the opposite panel to close the top opening, Formed on each corrugated medium is at least one set of score lines of various geometric shapes and orientations. The score lines act as folding lines that enable the panels to bend along different axes so that the overall shape of the shipping container better conforms to the object placed in the interior pocket.

Abstract: A carrier for transporting articles through pneumatic tube systems is disclosed. The carrier has first and second shells disposed about a longitudinal axis and connected by hinges such that the shells are moved transversely relative to one another when opening and closing the carrier. A seal such as a gasket or rubber seal is included within the interior of the carrier. Optionally, a sensor is used to indicate the presence of an abnormal condition within the carrier. Optionally, a lock is used to prevent opening.

Abstract: An ice preventing device for use with an outside gas pressure regulator that has a pressure vent and a downwardly opening vent tube. The device includes a skirt connected to and surrounding the vent tube. The upper end of the skirt has an opening that communicates with the passage in the vent tube. The skirt also has an enlarged, flared-out lower end with an opening substantially greater than the area of the opening at the upper end. Located within the skirt is a baffle positioned in a generally horizontal plane. The baffle is positioned below the vent tube opening of the pressure regulator to prevent rain or freezing rain from splashing back upwardly into the passage.
