Various improvements of a modular wall assembly of the type having panels with channels formed along the side edges of the panels are described. The improvements include the formation of at least the channels, and the surface of the panels adjacent to the closed ends of the channels, of a material resistant to the passage of electrical radiation. Connection assemblies are provided for the joinder of adjacent panels located either in the same plane or in intersecting planes which include elements...

In an electroluminescence panel, first and second charge injection refraining layers are formed between transparent electrodes and a first insulating layer and between back electrodes and a second insulating layer, respectively, and first and second charge injecting layers are formed between the first insulating layer and an emitting layer and between the second insulating layer and the emitting layer, respectively. The charge injection refraining layers suppress the injection of charges into th...

A panel connector comprising first and second members and a lock. The first and second members define an axis. The first and second members are slideable in relation to each other along the axis. The members also are slideable in relation to each other transverse to the axis. The lock has engaged parts connected to the first and second members, respectively. The lock limits movement of the members transverse to the axis. The lock is disengaged by movement of the members axially relative to the l...

A modular building panel having an interlock mechanism for connecting building panels in series is disclosed, includes two metal sheets separated by an insulating foam core bonded to the sheets and a first interlocking member on one side and a second interlocking member on the other side. The male connector configuration as well as the female connector configuration in this invention are both formed of curvilinear surfaces. The male connector as well as the female connector extends outwardly fro...

A prefabricated insulation panel is provided by identical L-shaped panel halves where a lip on one panel half is secured to a sleeve of a second panel half, the lip of the second panel half similarly engaging the sleeve of the first panel half, providing a double sided panel which can accommodate an insulation layer between the assembled panel halves.

A composite panel comprises first and second sheets 20, 22 of a natural fibre material such as corrugated cardboard, each sheet 20, 22 having been impregnated with a liquid composition comprising a thermosetting resin, an extending liquid for the thermosetting resin and a catalyst for the thermosetting resin, the thermosetting resin having been polymerized, a cellular core 10 of a natural fibre material such as kraft paper, the cellular core 10 having been impregnated with a liquid composition c...

This invention comprises an improved fascia panel and method of securing the fascia panel to a plurality of mounting brackets. The fascia panel 11 comprises a first portion 18 which is substantially vertical when the panel is secured to brackets and a second portion 19 which is below the first portion 18 where the second portion 19 is at an angle with respect to the first portion 18 such that the lower edge of the second portion 19 is rearward of the front face of the first portion 18. A first a...

Improved liquid-gas contact or demister panels for gas treating equipment, wherein each panel is designed with inlet and outlet sections and is fitted with a shaped flange on one end. A high strength assembly or array of panels is provided by interlocking alignment and fastening apparatus, which includes the shaped flange, along with tabs and slots formed in each panel.

A panel system for office workstations wherein a display board is removably secured to a hanging bar, The bar has a bracket assembly for selectively and removably hanging it onto a selected surface and has flanges arranged in the bar which may receive the bracket assembly and which removably secure the display board on the hanging bar when the display board is oriented with the flanges in a predetermined position. The display board has a frame defined by top, bottom and side extrusions and corne...

An improved panel coupler has a hub assembly which releaseably and adjustably holds two or more panel clamps for coupling together two or more adjoining panels. The panel clamps have keeper ends which are captured and adjustable within a keeper channel in the hub assembly such that the panel clamps are infinitely adjustable about the hub assembly, and distal clamping ends which, in turn, are adjustable for clamping onto panels having different thicknesses.
