Abstract: A drone comprises at least one propeller for generating lift and an article containment area for containing an article to be carried by the drone. The floor of the article containment area comprises a dynamic support surface for supporting the article and allowing the article to move into, out of and through the article containment area. The dynamic support surface may be a conveyor belt forming the floor of the article containment area.

Abstract: A cell culture container is provided, comprising membrane bound compartments for growing and harvesting monocytes that allows replenishing and removal of feed media without the loss or death of cells.

Abstract: A sorting conveyor comprising a modular conveyor belt having a plurality of carriers along its length. Each carrier comprises an opening through the belt associated with one or more doors movable between a closed position occluding the opening and supporting a load and an open position not occluding the opening to drop the load at a selected drop position.

Abstract: A conveyor system with a diverting conveyor belt crossing and intersecting a main conveyor line. The diverting conveyor belt has rollers on its outer side that rotate freely in the main conveying direction of the line. The downstream edge of the diverting conveyor is selectably tilted between a lowered, untilted position level with the main conveyor line and a raised, tilted position above the level of the main conveyor line. When the diverting belt is untilted and stopped, an article passes over the belt's rollers without being diverted. When the diverting belt is tilted and running, it diverts articles off the side of the conveyor line. In another version the rollers include an electrically conductive or magnetic material. A linear-motor stator under the diverting belt selectively actuates the conductive or magnetic rollers to draw undiverted articles across the belt.

Abstract: A missort prevention system prevents missorts in a sortation conveying system. The missort prevention system includes a sensor for detecting the presence of an unexpected article on a chute transitioning articles off of a conveyor and a missort preventer for blocking the further passage of the unexpected article on the chute.

Abstract: An article-diverting modular conveyor belt employs an article mover on a conveyor belt module for selectively moving a conveyed article towards a side of the module. The article mover may be a transversely-extending endless belt for carrying articles across the belt towards a side of the module. Rollers below the conveyor belt are selectively activated to induce movement of the article mover.

Abstract: Embodiments of the disclosure include systems and methods for capturing particular biological matter from a sample from an individual. The systems and methods employ an apparatus (such as a container that is a tube or bag) comprising a fluoropolymer coating that is modified to comprise one or more moieties for binding of a desired biological agents when a sample is exposed to the modified fluoropolymer. In particular aspects, the biological matter is a particular type of cell, such as a particular blood or bone marrow cell, and the desired cell is captured by means of an aptamer selected to bind the cell.

Abstract: A sorting conveyor including a diverting conveyor and a bidirectional assist roller to help sort articles over the side of the diverting conveyor. The diverting conveyor includes, in one version, a conveyor belt with diverting rollers selectively actuated to push articles toward a side of the diverting conveyor. The bidirectional assist roller rotates on an axis parallel to the main conveying direction. As articles to be diverted reach the side of the diverting conveyor, the bidirectional roller rotates in a direction to assist articles over the side of the diverting conveyor and the bidirectional roller and onto an exit conveyor. When the diverting rollers are not actuated, the bidirectional roller rotates in the opposite direction to prevent articles from exiting the side of the diverting conveyor. In some instances, the bidirectional roller can be raised above the level of the diverting rollers to further block articles not selected for sorting from exiting over the side and onto the exit conveyor.

Abstract: Platinum and iridium in catalytic electrodes for electrochemical uses is partially replaced with lead ruthenate-tantalum oxide composite. Electrodes are fabricated by first coating a film-forming metal substrate with a platinum-iridium composite undercoat, then overcoating with a composite containing lead, ruthenium, tantalum, platinum, iridium and oxygen. The most preferred anodes have a titanium substrate initially coated with approximately at least 2 gm/m.sup.2 of 70:30 .sup.w /o Pt:Ir composite, followed by about 20 gm/m.sup.2 of a composite having the nominal composition of 22.2.sup.w /o Pb.sub.2 Ru.sub.2 O.sub.6 ; 66.6 .sup.w /o Ta.sub.2 O.sub.5 ; 7.9 .sup.w /o Pt and 3.4 .sup.w /o Ir. The outer layer of the prepared anode contains from about 10 to about 16 .sup.w /o lead, from about 40 to about 65 .sup.w /o tantalum, from about 5 to about 7.5 .sup.w /o ruthenium, from about 6.0 to about 10 .sup.w /o platinum, from about 2.5 to about 5 .sup.w /o iridium, and from about 10 to about 20 .sup.w /o oxygen.

Abstract: A solar energy collector having improved absorptance and emissivity levels comprising: (1) a silver-copper oxide-rhodium oxide solar absorption film, (2) a cerium oxide interlayer and a substrate of quartz, silica glass or metal. The cerium oxide interlayer minimizes agglomeration of the metal particles, maintains a relatively low thermal emittance and improves overall stability.
