Abstract: Herein disclosed is a band for forming a seedling raising bottomed pot aggregate, in which multiple rows of a plurality of pots are aggregated. The bottoms of the pots are formed by making specific planar structures in a material paper having a constant width and by adhering, combining and cutting the paper. The pot aggregate can be easily manufactured by expanding the band. The bottoms are extended from the lower sides of the side walls of the cubes and are folded inward at a right angle from the adjoining extensions. These adjoining extensions are adhered on one of the diagonals of the bottoms, and the extensions on the other diagonal are overlapped.

Abstract: A self-supporting tent structure for protecting small private aircraft and the like comprises a plurality of vertical side posts each defining a corner of the tent to which a roof membrane is secured. A lifting apparatus is connected to the roof membrane for selectively moving the roof member between an untensioned position and a tensioned position. A truss member is provided for supporting steadying struts against the side posts for providing stability to the self-supporting tent.
