Abstract: A structural barrier and energy absorbing device comprises a plurality of structural elements. The structural element alone or in a plurality may serve as a traversal impediment or energy absorbing device, such as a pedestrian barrier, vehicular barrier, anti-tank obstacle, ballistic barrier, or the like. The structural element may be a tetrapod such that it comprises an element body having four extension portions that extend outwardly from the interior center to a distal end, such that the structural element maintains an identical orientation and a low center of gravity in each of four resting positions. The structural element may be a solid-state structural element comprised of a particular material or a portable and collapsible structural element wherein the element body comprises an outer skin defining an interior void space, such that during set-up or installation the interior void space may be filled with a filler substance onsite.

Abstract: A concrete-based composite material including iron rich particles is characterized by an iron content greater than 17% by weight of the composite material, can include iron particles which are an iron by-product recovered from iron slag material, can include iron rich particles which have an iron content of at least 60% by weight of the iron rich particles, and/or can include iron particles having a particle size distribution in the range of about ?? inch to +60 mesh or in the range of about ?20 mesh to about +60 mesh. The composite material can include ground granulated blast furnace slag as a portion of the cementitious component of the composite material. A method of forming a structural element from the composite material includes casting the structural element such that the structural element is characterized by a ballistic performance of Level 10 as defined by Underwriters Laboratories standard UL752.

Abstract: A system and method for installing a water diversion system to a cooling tower flume and distribution basin to dam a section of the basin includes installing first and second basin dams extending radially from respective first and second parapets of the flume wall to the basin wall in sealing contact with a basin floor, blocking water from flowing from the undammed section of the basin into the dammed section using the basin dams, and installing a flume dam to each notch of one or more notches distributed peripherally along the flume wall between the first and second parapets, blocking water from flowing from the flume into the distribution basin through the one or more notches using the flume dam, and such that the flume dams installed to the one or more notches in combination with the first and second basin dams define a dammed section of the basin.

Abstract: A method and system is used to process slag material to yield by-products including a finished iron rich product and a finished low iron fines product. The by-products may include a finished high iron product and a finished medium iron product. The method and system include size classifying the material into a plurality of sized groups prior to using magnetic separation to separate at least one of the sized groups into two portions having differing magnetic susceptibilities. The method and system may include more than one phase of size classifying the material into a plurality of sized groups and using magnetic separation to separate at least one of the sized groups into portions, where the average size of the material remaining after one phase is reduced prior to the subsequent phase.

Abstract: A containment apparatus and a method for installing the same is provided. The containment apparatus includes a plurality of panels, each of which extends along a height and comprises a panel perimeter including a plurality of perimeter portions, and a panel interior disposed within the panel perimeter. The plurality of perimeter portions includes an attachment border, a coil border, and a set of opposing side portions, which define a respective panel width therebetween. When the containment apparatus is in the installed position, the attachment border of a respective panel is operatively attached to the roof of a structure, such that the plurality of panels and at least one of the exterior walls of the structure cooperate to define a periphery of an unmanned aerial vehicle (UAV) containment area. The UAV containment area defines a controlled environment, directly adjacent to the structure, within which UAV may operate to inspect the structure.

Abstract: A barrier includes at least one support panel having a first face and a second face and a first bend intermediate the first face and the second face is provided. The support panel is deployable from a folded and packed condition to a freestanding condition, and is re-foldable to a packed condition. In the freestanding condition at least one expandable wire coil is operatively attached to the support panel to form the barrier. The expandable wire coil may be made of barbed wire, razor wire, or concertina wire. The support panel includes a diagonal brace and may include a generally horizontal brace. Retention cable may be strung through the wire coil to retain the wire coil to the support panel. The barrier may be provided as a deployment kit including the barrier materials in a packed condition. A method of deploying the barrier is provided.

Abstract: An entanglement obstacle for obstructing an area of a surface includes a mesh layer suspended over upright perimeter members via a perimeter cable and over upright central members via a central cable. The upright members are operatively attached to the surface. The perimeter cable is operatively attached to the perimeter members at a perimeter clearance above the surface to provide a trip impediment. The central cable is operatively attached to the central members at a central clearance above the surface to provide a step-over impediment. The central clearance is greater than the perimeter clearance. The mesh layer is operatively attached to the perimeter and central cables such that the mesh layer covers the obstructed area to provide an entanglement obstacle. The mesh layer is inclined from the central cable to each of first and second sides of the obstacle at an angle defined by the central perimeter clearances.
