Abstract: Described are systems and methods for active weathervaning of a hybrid flight aerial vehicle, such as an unmanned aerial vehicle (UAV). Active weathervaning of the hybrid flight aerial vehicle during can be provided during vertical takeoff and landing (VTOL)/hover flight without the assistance of any low-speed wind sensors and during transitions between VTOL/hover flight and fixed-wing, wing-borne, horizontal flight. Additionally, active weathervaning can be provided during propulsion mechanism failure conditions where the aerial vehicle may be experiencing failure conditions associated with one or more propulsion mechanisms.

Abstract: An exemplary embodiment of the invention provides a method of preparing a reinforced refractory joint between refractory sections of a vessel used for containing or conveying molten metal, e.g. a metal-contacting trough. The method involves introducing a mesh body made of metal wires into a gap between metal-contacting surfaces of adjacent refractory sections of a vessel so that the mesh body is positioned beneath the metal conveying surfaces, and covering the mesh body with a layer of moldable refractory material to seal the gap between the metal-contacting surfaces. Other embodiments relate to a vessel formed by the method and a vessel section with a pre-positioned mesh body suitable for preparing a sealed joint with other such sections.

At least part of the outer surface of the vessel incorporates a web of metal wires embedded in the surface, the wires being mutually overlaid with openings formed therebetween. The refractory material penetrates into the openings. The web may comprise woven metal wires or non-woven wires or both. The web imparts resistance to cracking (or containment of cracks, once formed) and/or resistance to molten metal leakage if cracks develop. The invention also provides metal containment structures containing such vessels, and methods of producing the same.

Abstract: A vessel used for containing molten metal has a refractory liner with an exterior surface and a metal-contacting interior surface and is made of at least two refractory liner units abutting at a joint. A housing at least partially surrounds the exterior surface of the refractory liner with a gap present between the exterior surface and the housing. Molten metal confinement elements, impenetrable by molten metal, are positioned within the gap to partition the gap into a molten metal confinement region between the elements and at least one other region. For example, the other region may be used to hold equipment such as electrical heaters that may be damaged by contact with molten metal. A drain outlet positioned in the housing allows molten metal entering the gap to drain out of the gap at the drain outlet.

Abstract: A curvilinear metal transfer device with support and compression assemblies that help maintain a constant force on the transfer device's metal outer casing and refractory as the outer casing and refractory expand and contract due to temperature fluctuations. In one embodiment, the support assemblies are configured to apply force to the refractory to keep the refractory in tension with the outer casing to suspend the refractory relative the outer casing. Also disclosed are clamp plates that help hold the refractory in place, and nested lids that cover the curvilinear metal transfer device.

Abstract: A vessel used for containing molten metal, e.g. a trough section for conveying molten metal from one location to another. In some embodiments, the vessel employs refractory liner units of different thermal conductivity to maximize heat penetration into the molten metal from heaters in the gap, but to minimize heat loss at the inlet and outlet of the vessel where the end units contact the housing.

Abstract: Methods, programs products and systems are provided for presenting retrieved search engine results text items to a user on a display device through a graphical user interface configured to associate displayed text items with a search term modification action. Selecting a displayed text item through a graphical user interface component cursor routine automatically instigates modifying of the search term through the associated modification action with the selected text item to generate a modified search term and causes a search engine component to search the modified search term and retrieve new search results similarly presented, enabling additional automatic iterations of search term modifying, searching and result presenting. Modifying a search term may occur automatically or through a selection from a generated list of revising actions, and presenting search results text items may include ordering and presenting a list of result text items relative to an occurrence frequency.

Abstract: Exemplary embodiments of the invention relate to a compressive rod assembly for applying force to a refractory vessel positioned within an outer metal casing. The assembly includes a rigid elongated rod having first and second opposed ends, a threaded bolt adjacent to the first opposed end of the elongated rod, and a compressive structure positioned operationally between the elongated rod and the bolt. Compressive force applied by the bolt to the elongated rod passes through the compressive structure which allows limited longitudinal movements of the elongated rod to be accommodated by the compressive structure without requiring corresponding longitudinal movements of the bolt. Exemplary embodiments also relate to rod structure forming a component of the assembly, and to a metal containment structure having a vessel supported and compressed by at least one such assembly.
