  • Patent number: 8939753
    Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.

  • Patent number: 8394310
    Abstract: An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions.

  • Patent number: 8382467
    Abstract: A multiple part mandrel on which a hollow body may be formed includes multiple sectors. Each sector has a skin on an outer face and a pair of opposed side returns at longitudinal sides of the sector. The mandrel formed by the sectors is symmetrical about a central axis of the mandrel. When the sectors are assembled as the mandrel, the side returns of adjacent sectors face each other. Each of the side returns includes a recess in an outside surface of the side return, spaced from the skin of the respective sector, and an inflatable O-ring disposed in the recess. The recesses of adjacent side returns in the mandrel are offset with respect to each other in an axial direction of the mandrel. Inflation of the inflatable O-rings urges adjacent sectors together at the skins of the sectors to seal the adjacent sectors at the skins.

  • Patent number: 8268225
    Abstract: A medical device in which a part to be secondarily shaped comprises a molded silicone rubber article is subjected to heatless shaping by irradiation with electron-rays. The irradiation with electron-rays enables shaping and, furthermore, sterilization under some conditions. In a medical device comprising a part in which at least a silicone rubber is used and the mechanical properties of the silicone rubber preferentially appear, the shape of the above-described part upon molding is deformed with the use of a correcting member to a level exceeding the desired deformed shape and maintained in this state. Next, electron-ray irradiation is conducted in this state and then the correcting member is eliminated. Thus, the desired deformed shape intermediate between the shape upon the molding and the shape upon the electron-ray irradiation can be obtained.
