Abstract: Arrows comprising a shaft having its original orientation through the die in which it was prepared marked or otherwise indicated. Any suitable marking or other indication can be used. The arrows may be pre-grouped and bundled. The shaft may be prepared with any suitable process including extrusion and pultrusion.

Abstract: An apparatus is disclosed for use in the exercise of the human body, which comprises a fiberglass pultruded shape of a predetermined oblong geometry with an elastic sheath formed about the exterior thereof over the length of the fiberglass pultruded shape. The fiberglass pultruded shape has fiberglass filaments dimensionally stabilized in a hardened resin system. Material properties of the filaments in the resin system are selected such that the ultimate elongation design value of the filaments and the resin system is greater than the actual maximum elongation of the filaments and the resin system when the fiberglass member is flexed in the exercise process. Also, the resin is selected for toughness sufficient to provide a useful flexural fatigue life.

Abstract: The invention relates to a method of manufacturing a sign or similar article by providing a fiber reinforced plastic laminate structure having pre-selected dissimilar laminate layers. After sandblasting, the dissimilar materials that have been exposed present different textured patterns to the observer, and therefore allow the sign designer greater latitude in the design and layout of the sign. Portions of the sign material may extend outwardly or downwardly from the sign body, for connection to the ground or any other secondary support structure. The materials of construction of the sign apparatus significantly enhance the longevity of the structure, as compared to the sandblasted wooden structures currently being used which are subject to rot or decay.

Abstract: Apparatus is disclosed for use in the exercise of the human body, which comprises a fiberglass pultruded shape of a predetermined oblong geometry with an extruded rubber compound sheath formed about the exterior thereof over the entire length of the fiberglass pultruded shape. The fiberglass pultruded shape has fiberglass filaments dimensionally stabilized in a hardened resin system. Material properties of the filaments in the resin system are selected such that the ultimate elongation design value of the filaments and the resin system is greater than the actual maximum elongation of the filaments and the resin system when the fiberglass member is flexed in the exercise process. Also, the resin is selected for toughness sufficient to provide a useful flexural fatigue life.

Abstract: A sucker rod construction including a connector member being formed to define a rod receptacle having a closed axially inner end and an open axially outer end. The rod receptacle has a plurality of axially spaced, tapered annular surfaces. The end of a cylindrical fiberglass rod is received within said rod receptacle through the outer end and cooperates therewith to define an annular chamber between the outer surface of the end of the rod and the tapered annular surfaces. A bonding material is positioned in the annular chamber and bonds the outer surface of the end of the rod and the tapered annular surfaces. Each of the annular surfaces has an angle of taper with respect to the outer surface of the fiberglass rod, and each angle of taper is progressively less toward the open end by at least one and one-half degrees.
