  • Patent number: 9987772
    Abstract: A method of building a Pre-stressed composite part is described herein. The method includes: fabricating a Pre-stressed composite part with a Prepreg (Pre-impregnated—already Resin coated fabric or tape) ply layup on tool or mandrel; laying conduits at desired locations and to be embedded with chopped fiber (metal or composite); inserting a steel cable into the conduit center and a calculated tension applied to the cable and held by jacks; filling the conduit with a special resin with hardener and allowing the resin to set until the cable is locked in the resin with the applied tension in the cable; removing jacks and leaving permanent anchors at both ends of conduit; applied cable tension creates compression in the part to take more tension for the loads and hence cable tension gives extra strength to the part.

  • Patent number: 9981412
    Abstract: A tubular lower mold partitioning wall is erected on a lower mold, and a three-dimensional mesh-like body is disposed with a part of a side face exposed with respect to the lower mold partitioning wall. When a pad main body is molded by foaming a liquid raw material, the mesh-like body is penetrated through the pad main body in a thickness direction. Since the mesh-like body is disposed with a part of the side face exposed with respect to the lower mold partitioning wall, the liquid raw material is hardened between the fibers on the side face of the mesh-like body, and the side face is attached to the pad main body. Therefore, it is possible that the mesh-like body is not easily displaced with respect to the pad main body while suppressing a sweaty feeling.

  • Patent number: 9969107
    Abstract: Methods and apparatus for demolding a polymeric material from a mold are disclosed, the methods comprising the steps of placing a material within a mold, closing the mold, molding the material located within the mold, and opening the mold. The mold includes a demolding tool having a material-engaging portion that is in fluid communication with the mold portion, the demolding tool being reversibly disengagable from the first mold member. The demolding tool is disengagable from a resting position within the first mold member to translate from the first mold member the molded polymeric material associated with the material-engaging portion, thereby separating a portion of the molded polymeric material from the mold cavity. In particular embodiments, the material-engaging portion is a cavity. In other embodiments, the material-engaging portion is associated with one or more longitudinal members extending across a portion of the first mold member.

  • Patent number: 9968504
    Abstract: A method which allows creation of an ornamental urn from an object such as horns, antlers, rocks, or the like. The method generally includes steps which form an ornamental urn adapted to resemble an object. The ornamental urn may include an access port having a funnel portion leading to an inner cavity adapted to store particulate materials, such as cremated remains. A plug, which may include a burr edge, is also provided to close the access port. The urn is fabricated by coating the object in a first coating to create an object mold, forming a second coating around the object mold to create an outer casing, and uniformly distributing a casting material along the inner walls of the object mold. After the casting material has cured, the ornamental urn may be removed from the object mold and finished to closely resemble the original object.

  • Patent number: 9956706
    Abstract: A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.
