  • Patent number: 11992739
    Abstract: An apparatus for precisely and accurately measuring the loft and lie of a golf club, and a method of using such apparatus, is disclosed herein. The apparatus includes a clamp assembly powered by a pressure unit to immobilize the head of a golf club, a scoreline measurement unit to capture scoreline angle information, loft and lie measurement arrays that can be moved along horizontal y and x axes to capture loft and lie angle information of the golf club shaft, and a computer with an algorithm that uses information captured by the scoreline measurement unit and loft and lie measurement arrays to calculate final loft and lie angle values that are accurate within +/?0.125°.
    Type: Grant
    Filed: September 6, 2023
    Date of Patent: May 28, 2024

  • Publication number: 20180185912
    Abstract: A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).
