  • Interchangeable golf club grip with shaft attachment system
    Patent number: 12036458
    Abstract: A golf club grip may include a docking tube and an elongated handle. The docking tube may be configured to couple to a golf club shaft and may include a docking tube sidewall. The elongated handle may be detachably couplable to the docking tube. The elongated handle may include an elongated handle sidewall defining an axial opening configured to receive the docking tube. At least one of the docking tube sidewall and the elongated handle sidewall may include a projection and the other of the docking tube sidewall and the elongated handle sidewall may include a channel. The channel may be configured to receive the projection to prevent rotation of the elongated handle relative to the docking tube when the elongated handle is coupled to the docking tube.

  • Renewable furan based amine curing agents for epoxy thermoset
    Patent number: 11629220
    Abstract: The present invention relates novel furan based amine cross-linkers with improved thermomechanical and water barrier properties. The novelty of this invention is the use of aromatic, and hydrophobic aliphatic aldehydes to bridge two furfuryl amines, which yields a diamine or tetra amines with a significantly enhanced hydrophobic character. These diamine cross-linkers exhibit enhanced water barrier properties and thermomechanical properties when cured with both commercial and synthetic epoxies.
