Abstract: A radiant panel includes a first and second skins and a fluid conduit between the first and second skins. The first and second skins each include an inner face and an outer face. The fluid conduit is formed in multiple rows, and is positioned within thermally conducting brackets bonded to an inner face of at least one of the skins. The thermally conducting brackets provide a thermally conducting path between the fluid conduit and the first and second skins of the radiant panel.

Abstract: An assembly for a framed system includes an elongated post and a mounting plate shaped for installation in a post channel of the elongated post. The elongated post includes a first rib integrated along an inner surface of the first lateral side and an elongated second rib integrated along an inner surface of the second lateral side. The mounting plate includes an aperture for receiving the fastener and includes a first slot for receiving the first rib and a second slot for receiving the second rib. When the mounting plate is installed in the post channel, the first and second ribs are deformed by the installation of the mounting plate such that the deformed first and second ribs retain the mounting plate in the post channel.

Abstract: A radiant panel includes a first skin and a fluid conduit. The first skin includes an inner face and an outer face and the fluid conduit is formed in multiple rows with at least a portion of the fluid conduit bonded to the inner face of the first skin. The fluid conduit of each of the rows has a serpentine configuration that provides structural support for the first skin.

Abstract: A head track for combination with a post and/or panel of a wall system, comprising an elongated extrusion comprising an elongated body and a pair of integral elongated wings extending normal to the body, the body having a T-slot located between the wings, the wings each having an elongated gasket secured thereto and protruding toward each other to define a receiving space therebetween for sealed engagement with the post and/or panel.

Abstract: Methods and apparatus for forming honeycomb structure from a plurality of substrate layers. The layers are bonded together by spaced, parallel, solid node strips of thermoplastic material pressed and heated above the softening temperature to bond to the substrate surfaces and form a block. After cooling, the block is expanded into a honeycomb structure. Alternatively, the solid node strips can be placed on the spaced raised crests of corrugated layers of substrate, and successive layers bonded together by pressure and sufficient heat between the crests of one layer and the corresponding depression of the successive layer, to elevate the node strips above the softening temperature. Several alternative methods and apparatuses for achieving the result are disclosed.

Abstract: A post and batten assembly for a wall panel system, the elongated post having a plurality of sides, at least one of which has an elongated groove and a pair of outer shoulders astraddle the groove, an elongated batten having a central body positioned in the elongated groove of and attached to the post, and the batten having a pair of flanges extending opposite each other and engaging the outer shoulders of the post, the batten central body having an outer face, and defining an elongated cavity open at the outer face, and the cavity having a pair of inner shoulders so that the cavity and inner shoulders define a T-slot in the batten to receive a T-bolt fastener. Fasteners connect the elongated batten to the post. Flanges of a pair of batten extend beyond the post parallel to each other to define a panel-receiving pocket therebetween.

Abstract: An impactor for a movable, deformable barrier, simulating an automobile, comprising an upright, solid backing support, a plurality of energy absorbing impact segments protruding from the support, each segment having an outer impact face and each comprising a plurality of layers of honeycomb having different crush strength characterized by increasing crush strength of successive layers from the outer impact face to the support, the layers being separated by and secured to perforate plates therebetween allowing air flow from a crushing layer to the succeeding layers when the layers are successively crushed and each impact segment having a thin vent layer of noncrushing slotted honeycomb adjacent the support for discharge of air from all of the segments as they are successively crushed. The layers in each segment are of essentially the same width and height. A solid face sheet is at said outer impact face of said segments.

Abstract: The specification discloses a structural honeycomb core fabricated of crystalline theremoplastic to provide corrosion-resistant, heat-resistant, high-impact structure. The core includes inter-welded strips forming a rigid core. In a first embodiment, the linear strips are welded and then expanded to form a honeycomb core. In a second embodiment, the strips are corrugated prior to welding.

Abstract: The specification discloses an air-to-air, polymeric heat exchanger having a housing and a core removably mounted within the housing. The housing includes four generally indentical duct units, which are secured to one another, and a top and a bottom, which are secured to the duct units. The core includes a pair of end walls and a plurality of tubes extending between, and opening through, the end walls. Each end wall includes a plurality of tubular projections or pockets extending from the end wall in a common direction. Opposite ends of the tubes are secured within the tubular pockets in the opposite end walls. A method of constructing the core includes the step of severing the tubular projections after the tubes are positioned therein to expose the tube interiors through the end walls. Preferably, the tubular projections are severed using a hot wire to also fuse the tubes within the end walls.
