Abstract: A resilient unit has strings of individual coil springs (not shown) inside pockets 120 are arranged in an array. The strings together form a spring unit and are each secured to a common cover sheet S, which comprises a non-woven elastic fabric. It is welded ultrasonically or thermally whilst under tension in one or both of its major dimensions—i.e. in-plane—to the pockets 120, the material of which is substantially inelastic and non-woven. In this example the welds, labelled W, are located substantially centrally with respect to the generally circular end surfaces of the pockets.
Abstract: Systems, methods, and articles of manufacture provide for a mold system for molding structures (e.g., sand castles) from one or more various types of molding substances (e.g., sand, clay, snow). In one embodiment, a mold system comprises a split mold comprising at least two mold sections. In one embodiment, a modular mold system allows for different types of mold sections with corresponding joining elements to be joined together to create forms for molding various types of structures. In some embodiments, mold sections are configured to facilitate the breaking of a vacuum created when molding substances are packed into the mold system, thus making it easier to separate a mold from the formed structure.
Abstract: A barrier wall is formed by rotating a mold to a horizontal orientation so that a rear wall of the mold is horizontally disposed and an encircling sidewall upstands from the rear wall, the floor and encircling sidewall at least partially bounding a compartment, an upper end of the encircling sidewall at least partially bounding a first access opening to the compartment. A first material is disposed into the compartment through the first access opening, at least a portion of the material being curable. A cover is placed over the first access opening to enclose the compartment. The mold is then rotated from the horizontal orientation to a vertical orientation. A portion of the sidewall is then moved to form a second access opening to the compartment. A second material is then dispensed into the compartment, at least a portion of the second material being curable.

Abstract: A structure installation system which maintains one or more walls in a desired position and orientation during installation of the one or more walls. The structure installation system generally includes a vehicle which is adapted to traverse a ground surface. The vehicle includes an arm having an arm coupler to which a support is connected. One or more walls adapted to be installed in the ground surface may be removably connected to the support, such as by securing the walls to adjustable hangers that are removably connected to the support. By adjusting the positioning of the hangers, the orientation and position of the walls may be adjusted. Once put in position, the vehicle and support will retain the walls in the desired position and orientation while concrete is poured and allowed to cure to form a unitary structure such as a bollard wall.
