Abstract: The present invention is a system for displaying decorative articles on backpack straps incorporating a backpack, two backpack straps each with a plurality of decorative article receiving openings incorporated thereon, and decorative articles having a decorative face, a stem and an elongated fastener whereby said stem and elongated fastener is constructed and arranged to attach to said backpack straps through said decorative article receiving openings.

Abstract: An apparatus and method for molding composite material with a selectable uniform predetermined temperature during most of the curing time. The mold apparatus has two cooperating and complementing mold bed assemblies hingedly mounted to each other and movable between two extreme positions, open and closed. A composite inner skin and outer skins sandwich a spacer in between. The spacer member includes interconnecting passages throughout. An outer perforated composite skin member covers the spacer member. A source for pressurized gas is applied to the mold assemblies when in the closed position. A predetermined cooperative temperature is selectably used to uniformly control the curing characteristics of the first and second skin members as the pressurized hot gas or air forced to pass through the outer skin and the spacer member adjacent to the inner skin thereby exposing the form being molded to a uniform temperature gradient.

Abstract: The scope of this invention is the manufacturing of a new shell mould of a braced constitution by randomly distributed ribs, which is used for the manufacturing of windmill blades, as well as the disposition and conformation of the fabric constitutive fibers and the plies used in the constituted pattern. The loads supported by the structure and the deformations produced during curing process are absorbed by the ribs, which are distributed along mould and displayed according to the weight each of them sustain. These ribs sit on a composite bed, remaining screwed and bonded to it. This distribution of the ribs allows the introduction of an air circulation channel inside mould, whose shape is adjusted to blade profile. The air circulation is uniform and unexpected dilatations are avoided because they are absorbed by the braced structure that produces an accordion effect.
