Abstract: A plurality of struts are coupled together by a plurality of connection systems for creating a geodesic dome skeletal structure. Each connection system includes a single first connection member including a center body portion having a plurality of cylindrical fingers extending therefrom and a plurality of second connection members. The number of second connection members employed at a specific connection point is proportional to the number of fingers on the first connection member. Each second connection member includes a tubular housing having an inner semi-circular portion mounted along an inner circumference for mating with an outwardly extending semi-circular portion of each cylindrical finger. The mated semi-circular portions form an interface for frictionally locking the tubular strut to the connection system between the first and second connection members.

Abstract: Coupling apparatus for releasably interconnecting cargo pallets to form trains thereof for transporting exceptionally long cargo usually co-mingled with cargo of more normal dimension. Such apparatus is operative to preserve the trainlike arrangement of such pallets, one to another, throughout movement over, and transfer between, various conveying apparatuses customarily employed for the handling of said pallets even though the apparatuses may be misaligned, one to the other, either laterally, vertically or angularly or combinations thereof. The coupling apparatus is particularly adaptable to pallets framed by extruded members having a plurality of spaced apart symmetrically distributed recesses formed therein and, in coacting relationship with alternate recesses, a plurality of hingedly mounted securing rings.
