Abstract: Composite structures and methods of forming composite structures are provided. The composite structures can include one or more composite structure components. Each composite structure component is formed from a composite panel that includes one or more sheets of material. The sheets of material include a thermoplastic material and a plurality of reinforcing fibers. A composite panel can be formed in three dimensions to form a composite structure component. Multiple composite structure components can be fused to one another to form a composite structure. In addition, each composite structure component and the composite structure formed therefrom can include an aperture. An interior volume can be formed between adjacent composite structure components. Methods for forming a composite structure can include a step of simultaneously molding and fusing composite structure components.

Abstract: An apparatus for moving a document towards the bottom of a document track as the document is moved in first and second directions within the track. The apparatus includes a feed unit positioned on one side of the document track and a cooperating unit positioned on the opposed side of the track. The cooperating unit has a rod which is pivotally supported in a support. A high friction roller is secured to the top end of the rod and a low friction roller is rotatably supported on the lower end of the rod. The feed unit has an idler roller positioned opposite to the high friction roller and also has a drive roller positioned opposite to the low friction roller in the cooperating unit. As the document is moved in a first direction in the document track, the high friction roller causes the rod to pivot slightly, thereby causing the low friction roller on the bottom of the rod to cant slightly, producing a downward component of force on the document as it is moved in the first direction.
