Abstract: A three-dimensional structure adapted for use for instance as a core in sandwich panel-type construction, and comprised of substantially continuous unbroken sheet material to which has been imparted an alternating sequence of ridges and valleys, creating spaced rows of adjacent inclined rectangular-shaped facets connected by intermediate rows of adjoining parallelogram-shaped facets. The core structure provides substantially gridlike bearing surfaces on two opposing parallel bearing planes thereof to which face sheets may be affixed, to form a sandwich panel.

Abstract: A suspension device for cable or the like, formed of nonmetallic flexible material woven or braided into elongated, tubular or sleeve-like form so that the cable or a like flexible linear body, can be passed through the central passageway of the suspension device and out an opening formed in the defining sidewall of the device and be frictionally gripped or held by the device against lengthwise movement relative to the suspension device, and wherein the latter can be formed at one end thereof into a self-retaining loop for securing the device and gripped cable or other linear body to an overhead support, thus transmitting any tensile load applied to the cable or other linear body to the support via the suspension device and thus preventing any tensile load being transmitted along the cable or other linear body to its connection point, such as, for instance, an electrical junction box.

Abstract: An enclosure assembly enabling the selective covering of an area such as the bed of a pickup truck of the like. The assembly includes a plurality of extendable and collapsible cover sections interconnected by an actuating system. The actuating system enables the rear cover section of the assembly to be pivoted to a collapsed or extended position by a pivoting structure having unique cam and leverage characteristics. The entire assembly can be selectively power operated or locked into position using a clutch mechanism associated with the actuation system. The enclosure assembly affords simple and effective operation to provide for the convenient use of the truck bed or similar area.
