Abstract: A rectangular sandwich panel comprises two skins with an insulating material, such as foam, sandwiched therebetween. Two spaced apart arms form a double tongue on each of two adjacent circumferential edges of the panel and a cooperable double groove is formed along the other two adjacent circumferential edges, whereby, without additional coupling means, the panel can be assembled on all sides by a tongue and groove connection with adjoining panels. At the corner of the panel, where two double tongues meet, the arms of the double tongues are cranked so that the spacing between the arms forming the double tongues is increased by the thickness of the arms, to accommodate the arms of double tongues of an adjoining panel.

Abstract: A multiplanar device has at least one component that consists of two rigid plastic wall members that have major areas of substantially uniform thickness, strips of considerably greater thickness along the side portions of said wall members, and a miter joint between the two wall members. A continuous thin film of flexible plastic is bonded to the two wall members and around the outside of the miter joint.The method of making the component is to mold it as a flat intermediate piece with a V-notch between the strips of greater thickness and to simultaneously bond the film to the surface at the apex of the V; and to thereafter apply adhesive to the sides of the V and bend the piece to bring the sides of the notch together and bond them together.Several such components may be connected with other similar or dissimilar components at miter joints to form a complete multiplanar device.

Abstract: Laying floor tiles is more convenient because the floor tiles are provided with tongues which can be fitted readily into grooves in adjacent tiles because the depth of each groove is less than the magnitude of the portion of a tile which is overhanging a portion of the adjacent tile. Such overhanging and underfitting relationships supplement tongues along adjacent sides into grooves of two adjacent tiles. Peripheral floor tiles can be anchored, but central area tiles can be free from the conventional adhesion to the subflooring. Venting for moisture equilibration between the atmosphere and a sub-flooring such as a concrete slab is achieved because of the absence of adhesive between vertical walls of adjacent tiles.

Abstract: A process for producing veneer and fancy plywood therefrom having a combination of wood grain patterns and line patterns includes cutting out a symmetrical pattern piece from a section of wood and inserting the pattern piece into a hole in a section of wood in which the hole has a cross sectional configuration corresponding to the cross sectional shape of the pattern piece. The pattern piece is inserted into the hole in a position different from the original position and is subsequently secured therein utilizing an adhesive. Slices of veneer are cut from the section of wood such that the sliced veneer includes wood grain patterns of the pattern piece and the section of wood.

Abstract: A corner formation is made in an architectural glazing strip that has an elastomer-encased spring material formed of a resilient wire element in a transverse pattern of zig-zag loops with the strip having an anchorage edge and a glass-engaging edge. The strip is cut inward from the anchorage edge between the pair of wire loops that occur at the corner, and the cut is stopped at the wire extending between the pair of loops. Then the strip is bent 90.degree. at the corner to open a substantially square space between the wire loops. A resilient element is placed in this space and has the transverse cross-sectional shape of the spring material, and an elastomeric material encases the resilient element and is secured to the strip around the corner. The result provides an even and uniform corner having resilient pressure all the way around the corner.
