A display panel includes a plurality of gas-filled cells which comprise apertures in an insulating plate, and each cell has a cathode at its lower end and an anode at its upper end, from which light exits to a viewer. The walls of the cells are made of light-reflecting material so that nonaxial light rays generated at each cathode reflect back and forth upwardly along the cell walls and exit at different angles. With light rays thus exiting at a wide range of angles, an effective wide viewing an...

A panel assembly for constructing a building, comprising a plurality of panel elements in juxtaposed relation. The panel elements are generally rectangular and have peripheral rims and a flange extending from each of a pair of opposed sides of the rims. The panel elements have a lightweight core of hard plastic foam with a fiber glass reinforced resin covering and reinforcement rods (e.g. at the corners of the panel element) embedded in the resin and bonded to the core and the covering. An apert...

The invention relates to a fastening system (1) for rectangular, tabular panels (2, 3, 10), especially floor panels. Comprising retaining profiles disposed on the small faces of said panels (2, 3, 10). Opposite retaining profiles match said retaining profiles in such a manner that similar panels (2, 3, 10) can be interlinked. The panels are provided with opposite first retaining profiles that are configured in such a manner that on a panel (2, 3, 10) being in first line a new panel (2) can be lo...

This specification discloses a hinge for connecting a panel or the like to a support or for connecting two panels together. In the example, the hinge is shown connecting two panels. A bracket is attached to the edge of each panel adjacent the other. These brackets extend from the top of each panel to the bottom. Flexible hinge strips are supported between the panel edges. Each hinge strip has one of its edges clamped under one edge of one of the brackets and its opposite edge clamped under the o...

A modular office panelling system has been improved by providing an air circulation arrangement of selectively cool or remove heat from a particular area defined by the panelling system. Fans are provided in removable panel cover portions which can advantageously be secured in the office panelling system in the same manner as fabric covered removable cover portions. Thus, the air circulation arrangement may be provided as an original specification or added as a retrofit in the field. The interio...

A hollow sheet metal transom which can be readily made with a minimum of hand labor and can be assembled with, and disassembled from, sheet metal doorjambs by a comparatively unskilled workman using only simple tools.

A latch formed of a body piece having a bearing surface to contact one face of a panel and a shank to project through a circular panel aperture which shank is formed with a diametrical aperture, and a crosspiece inserted into the shank aperture to bear on the opposed face of a panel and having a tongue to engage a second panel upon rotation of the latch and a locking tab to extend into a said panel aperture along the body piece shank to positively retain the latch on a panel from movement along ...

A decorative panel product formed through compressing and consolidating a mat of loosely organized, bondable wood particles. The panel includes a medial portion having one thickness and one density, and a marginal portion having a substantially lesser thickness and a greater density than the medial portion. The panel's marginal portion is slotted, whereby a pair of spaced substantially parallel flanges are defined which can be squeezed toward one another to facilitate fitting the extremities of ...

A panel made up of an expanded metal mesh with frame members of split tubing receiving the edges of mesh and gripping it, and molded into a rigid unitary frame; and hinge means for mounting the panel on the support.

Walk-in coolers for maintaining a chamber at a temperature are assembled from sandwich panels, which are welded together in end-to-end abutting relationship. Each panel generally has an inner metallic facing and a spaced opposed metallic facing with the space between the facings filled with a thermal insulating organic material having a coefficient of thermal conductivity of less than 0.3 Btu/hr,ft.sup.2,.degree.F./ft. The abutting ends of the inner facings are welded together to cover the crevi...
