A single L-shaped modular building unit comprises an integral end wall and ceiling and incorporates an outwardly depending flange peripherally surrounding the entire modular unit. The overall ceiling length is equal to twice the ceiling width. The outwardly depending peripherally surrounding flange is rectangular along its exposed edge to provide a modular unit which can be easily interconnected with similar units in any desired arrangement. Along the interior facing edge of the flange, the overall rectangular shape incorporates radii of curvature at the ceiling-wall interface for additional aesthetic purposes. The interconnecting portion between the wall and the ceiling is a saddle-shaped curve extending both longitudinally and laterally substantially the entire length of the ceiling and down a substantial portion of the wall. The peripherally surrounding outwardly depending flange of each modular unit is readily interconnected while the saddle-shaped portion provides structural strength to support the weight of the ceiling. The short open end of the unit is closed with two window, wall, or door units which also acts as a support for that end of the ceiling. Four such units may be used to close the long open ends. Thus, structure of widely varying architecture may be built of more multiple units mounted on a floor, slab or deck.

In the manufacture of a molded article having a shell layer and a core, an intimate bond is formed between the shell layer and the core layer of the molded article, using a unique variation of the vacuum bag technique of sealing the peripheral edge of the vacuum bag directly to a portion of the article. Using this technique, while providing for greater flexibility in the selection of sealing positions, only the critical portion of the article is exposed to the vacuum, thereby allowing the noncritical area to be exposed to air. As a result, greater flexibility in the selection of sealing positions is provided and, in most instances, eliminates the need for tailor-made vacuum bags.

A wind deflector support system universally applicable for mounting to the roof of all different types of tractors and cabs is provided by employing a support system comprising a deflector bracket, a support column, a cab bracket, and an arcuately adjustable channel iron member. By providing a channel iron member having one end that incorporates a pivotable hemispherically articulating joint with the other end attachable to a rotatable bracket, a universal wind deflector support system is provided which is capable of being mounted to any type of cab configuration presently on the market, along with any type of cab configuration in the forseeable future.

Stacking and nesting containers are prevented from tilting into each other when in superposed stacking position by providing: (a) differing numbers of a plurality of tapered ribs vertically positioned and inwardly extending from top to bottom of at least one opposite pair of sidewalls; or, (b) same numbers of a plurality of tapered ribs vertically positioned and inwardly extending from top to bottom of at least one opposite pair of sidewalls, these ribs being unequally spaced one from the other and being of unequal width, but the ribs on the opposing walls forming mirror images of one another; or, (c) the combination of one pair of opposing walls conforming to arrangement (a) and the second pair of opposing sidewalls conforming to arrangement (b).
