Abstract: The golf aid disclosed herein includes a shell of rigid construction that engages the portion of the arm including distal posterior portions of a forearm, posterior portions of a wrist, and a back of a hand proximal to knuckles while leaving a palm and a thumb exposed. The shell is configured to control a wrist throughout a golf stroke by maintaining the wrist in a neutral position to prevent flexion and extension of the wrist during a golf stoke. Related methods of use of the golf aid may include wrapping a material about a portion of an arm and allowing the material wrapped about the portion of the arm to transform into the rigid state while gripping a golf club and maintaining the distal portions of the forearm, the wrist, the hand, and the golf club in alignment. The methods may include the step of maintaining the wrist in a neutral position thereby preventing flexion and extension of the wrist by engaging the shell with the arm while performing a golf stroke.

Abstract: The present invention is directed to methods for constructing a flange on a pipe using an additive manufacturing process, such as directed energy deposition, powder bed fusion, friction-stir, or diode laser cladding. The flange can be constructed on a pipe comprising an oxide dispersion strengthen or nickel-based alloys, in particular a precipitation strengthened nickel-based alloy, such that the pipe maintains its inherent mechanical and metallurgical properties, including hardness, tensile strength, yield strength, fracture toughness, creep strength, fatigue, which would otherwise be reduced based upon typical welding of a flange to the end of the pipe. The flange can be constructed around the exterior of a pipe at the end of the pipe to allow use of the flange in connecting the pipe via bolting to other piping components, such as another pipe with a corresponding flange, a valve flange, a pump flange, or any other type of flange.
