Abstract: Circuit panel rack apparatus includes a hanging rack having a slot with a sloping surface. A roller is movable along the sloping surface. The roller moves downwardly along the sloping surface to hold a circuit panel in the rack, and the roller moves upwardly along the sloping surface to release the panel. The upward movement of the roller along the sloping surface is caused by the upward movement of a stem secured to the roller. The roller is biased downwardly along the sloping surface and against the circuit panel by a compression spring disposed about the stem.

Abstract: A formable matrix used as structural material and having an admixture of reinforcing non-metallic fibers to control deterioration and improve flexural strength. The fibers are fabricated with a cross section which provides a maximum ratio of surface to cross-sectional areas and increased frictional forces between fiber and matrix when the fiber is stressed. The disclosed embodiment of the fibers has a cross-sectional shape with a plurality of arms extending radially from the center, preferably with lobes formed at their outer ends.
