Abstract: A system for basing drones is described. A network of geographically diverse hangars provides storage and charging locations as well as backhaul communications infrastructure and video monitoring. As drones are needed, a central command point tasks an available drone, which may or may not already be located in proximity to a target. If additional drones are needed, drones can be flown to the area of interest and continuous coverage provided by charging drones while an active drone is conducting the mission, then rotating charged drones into the active mission. Structures for the hangars, the overall system, and methods of operation are described.

Abstract: A process for producing olefins may include dehydrogenating a first alkane in a first reactor to produce a first effluent comprising at least one of a first n-olefin or a first diolefin; removing the first effluent from the first reactor; and regenerating the first reactor. The first reactor may include a first dehydrogenation catalyst and a first phase change material.

Abstract: A casing bead includes a base panel that, with the casing bead mounted at a vertical wall structure, is disposed along the vertical wall structure. A stop bead wall extends from an edge region of the base panel and includes a first side facing the base panel, an opposite second side and a flange extending from the first side and partially over the base panel. A flexible spacing element is disposed at the second side of the stop bead wall and includes a surface spaced from the second side by a pair of side walls. With the casing bead mounted at the vertical wall structure, an adhesive element at the surface of the flexible spacing element engages a structure adjacent the vertical wall structure to attach the casing bead at the structure. In response to expansion of the structure, the flexible spacing element is compressed toward the stop bead wall.

Abstract: Processes and systems for dehydrogenating ethylbenzene may include mixing a steam stream and an ethylbenzene stream to form a feed mixture. The ethylbenzene/steam feed mixture may then be fed to a dehydrogenation reactor containing an alkali metal promoted catalyst. A liquid, selected from an alkali metal liquid, an alkali metal compound liquid, or a liquid solution comprising an alkali metal, may be injected into a feed stream, such as the steam stream, the ethylbenzene stream, or the ethylbenzene/steam feed mixture. Following injection, the liquid vaporizes and disperses into the feed stream upstream of the dehydrogenation reactor. The liquid may be maintained as a liquid from a point upstream of injection to an injection nozzle. The liquid is dispersed through the injection nozzle, in liquid form, to form droplets of liquid dispersed in the feed stream, which evaporate and/or dissolve into the vaporous feed stream.

Abstract: A ventilation screed comprising: an attachment flange having a top portion and a bottom portion; a drip edge protruding from the attachment flange and a return leg that protrudes back from the drip edge, wherein the drip edge is angled downward in a first direction and the return leg is angled downward in a second direction; a drainage cavity protrusion protruding from the attachment flange above the drip edge, wherein the drainage cavity protrusion has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion and a substantially vertical portion with a top end and a bottom end in communication with the bottom portion, an upper ground portion in communication with the top end of the substantially vertical portion of the L-shaped drainage trough portion extending outward from the substantially vertical portion and a drainage cavity shroud extending substantially downward from the upper ground portion.

Abstract: An intermediary device to enhance and route data messages between end user and contact center agent computing devices in a contact center environment is provided. The intermediary device can be disposed in a data communication path of a contact center between an electronic communications network and a contact center agent computing device. The intermediary device can include a data message replication mechanism, a data message aggregator mechanism, or a data message analysis mechanism. The intermediary device can receive a data message. The data message replication mechanism can intercept and replicate the data message to generate a replicated data message. The data message analysis mechanism can generate, from the replicated data message, derivative content. The data message aggregator mechanism can combine the derivative content with the data message to create an enhanced data message that can be provided to the contact center agent computing device in the contact center environment.

Abstract: A casing bead apparatus includes a base panel with at least one opening through the base panel. With the apparatus mounted at a vertical wall, the base panel is disposed along the vertical wall. A stop bead wall extends from the base panel. The stop bead wall includes a first side, a second side opposite the first side, and a flange at a distal end of the stop bead wall distal from the base panel and extending partially over the base panel. A spacing element is disposed at the second side of the stop bead wall. An adhesive element is disposed at the spacing element. With the apparatus mounted at the vertical wall, the adhesive element engages a horizontal surface perpendicular to the vertical wall to adhesively attach the apparatus at the horizontal surface and the spacing element is disposed between the stop bead wall and the horizontal surface.

Abstract: A ventilation screed configured to be mounted at a vertical wall of a structure includes an attachment flange having an upper end region and a lower end region opposite the upper end region. A cavity structure is disposed along the upper end region of the attachment flange. The cavity structure has a first side, a second side, and a third side. The first side extends from the upper end region of the attachment flange. The third side extends over the first side and is spaced from the first side and from the upper end region of the attachment flange. The second side extends between the first side and the third side. At least one ventilation opening is formed through the first side of the cavity structure. A ventilation spacer extends from the first side of the cavity structure and is spaced from and extends partially along the attachment flange.
