Abstract: A modular guardrail system relates to a set of interconnected beams that each fit into pairs of detachable bases, thus allowing for the creation, adjustment, and removal of a variety of configurations of temporary fence-style barriers. Each guardrail section may include two vertical posts, one on each end of each guardrail section, connected by a set of horizontal beams and, in some cases, a horizontal toeplate. Adjacent guardrail sections share a common base, thus allowing for the chain assembly of an extended barrier. The base that connects to the guardrail sections may include several vertically-oriented brackets that may slide into the different guardrail posts. The placement of the vertical brackets upon the base is selected so that each of the attached guardrail sections can be arranged independently of one another in any direction. The vertical brackets may be rotatably attached, thereby allowing for more flexible arrangements of the guardrail sections.

Abstract: A force-absorbing barrier includes a plurality of chambers at least partially filled with fluid. The walls defining the chambers are flexible. Fluid passages in the interior walls between chambers allow fluid flow between the chambers. Alternatively, the chambers are filled with structures instead of or in addition to a fluid. The fluid flow from chamber to chamber and/or the deformation of the structures will absorb energy from the impact a motor vehicle, preventing the vehicle from impacting the terminal of a guardrail.

Abstract: A method for producing helices for a chain-link net, said helices for forming the chain-link net being interconnected, and rotated into one another, wherein the helices are produced from at least one longitudinal element, in particular a single wire, a wire bundle, a wire strand, and/or a wire rope, with at least one wire being partially implemented from a high-tensile steel, and wherein the helices are bent so that they include a plurality of first legs, a plurality of second legs, and a plurality of bending regions that interconnect a first leg and a neighboring second leg, wherein the helices are bent, by a braiding knife assembly comprising at least one braiding knife, in such a manner that at least the center points of the first legs and/or at least the center points of the second legs of a completely bent helix each lie substantially in one plane respectively.

Abstract: An irrigation system having a pipeline supported by one or more towers includes an improved truss connection system having a means for readily adjusting a crown height of the pipeline. A pair of cooperating members define a joint which selectively couples headed ends of adjacent truss rods together to form a truss rail of a truss system that supports the pipeline. A single fastener may fasten the cooperating members, a strut, and a cross-member together at the joint. A length of the truss rail may be decreased by holding the truss rods closer together. In an aspect, the headed ends of the adjacent truss rods are held closer together by inserting a shim in one of the joints. Decreasing the length of the truss rail increases the deflection of the pipeline and raises the crown height.
