Abstract: Ultra-High-Performance Concrete (UHPC), owing to its superior mechanical and durability properties, presents a unique opportunity for innovative use in unbonded post-tensioned floor systems. In unbonded post-tensioned (PT) slabs and beams, the use of cast-in-place steel confined UHPC Bond Anchors (UBA) can be used to anchor steel prestressing strands for better durability, increased strand ductility, cost-effectiveness, and ease of installation. A conical, steel confining device is used as part of the UBA. The device resists hoop tension and eliminates splitting cracks in the UHPC during prestress transfer. It also helps to reduce the anchorage length. High average bond stress helps reduce the UBA length, and consequently, the material consumption. The bond stress at the strand-UHPC interface can be increased by intentionally roughening or indenting the strand.

Abstract: A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof. The system also uses an anchor which includes a sleeve and a plug. The sleeve includes at least two legs extending toward a first end of the sleeve. The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

Abstract: A bidirectional, wedge clamp is disclosed. Conventional clamps, such as those used with electrical cables mainly secure a line in a single direction. The invention herein being comprised of a bidirectional clamp for conventional cables, wires and rope etc. (herein referred to as a ‘line’) having a simple and easily-operable construction, wherein two plate-like members and an outer sleeve-like member are telescopically assembled to clamp a line there between. Plates and sleeve members having a plurality of interconnected, opposing number of wedges that when acted upon in a lateral motion by a line there between, causing said wedges to slide against one another—thereby tightening down the plates onto said line and preventing slippage. An object of the invention is to clamp a line and prevent slipping laterally in either direction along the line's longitudinal axis.

Abstract: A strap for a security device has a core (12,62) within a flexible sleeve (14,64), and the sleeve is extensible independently of the core such that the core is not under tension. Because the core is not under tension, it is more difficult to cut and substantially inhibits, if not prevents, cutting of the sleeve. The core may take various forms which resist cutting in different ways. Examples are elongate, normally metallic planar bodies (12,34,38) having longitudinal flexibility but resistance to lateral flexure, and extensible springs (16,22,26). The sleeve (14,64) can also be designed to complicate any attempt to cut the strap as a whole, and may comprise multiple layers (76,78).

Abstract: A device wherein an elastic cord is attached to a pre-existing flexible linear structure such as a wire, tube or non-elastic cordage in order to deform the structure and impart elastic handling properties of a common curly cord. The resulting assembly is a foreshortened version of the linear structure that is axially elastic and therefore easier to handle, store and use. The preferred method involves creating attachments between one or more stretched elastic cords and a linear structure at close intervals along the structure, such that when the elastic is allowed to retract, it pulls the linear structure into a series of loops or bends.

Abstract: An improved method and apparatus is provided to secure a suture relative to body tissue. When a predetermined minimum force is being transmitted between a suture retainer and the body tissue, the suture is gripped with the suture retainer by plastically deforming material of the suture retainer. One or more bends may be formed in suture by the suture retainer to increase the holding action between the suture retainer and the suture. The bends in the suture may be formed by wrapping the suture around a portion of the suture retainer. During movement of the suture retainer toward the body tissue, the bends may be moved along the suture. One or more bends may be formed in the suture by bending a tubular member through which the suture extends. The tubular member may be maintained in a bent condition by a C-shaped holder member. Alternatively, the tubular member may be maintained in a bent condition by members which are latched together.
