Publication number: 20250226725Abstract: The present disclosure is directed to a power take-off device including a shaft member, first and second end plates coupled to opposing ends of the shaft member, and first and second cords. Opposing ends of the first cord are secured to the first end plate to form a first loop and opposing ends of the second cord are secured to the second end plate to form a second loop. The first and second loops are configured to be wound into a twisted state or a hyper-twisted state when the shaft member is rotated in a first direction. When opposing tensile forces are applied to respective end points of the first and second loops, the shaft member is configured to rotate in a second opposing direction, thereby creating a moment of inertia such that the first loop and the second loop are rewound into the twisted state or the hyper-twisted state.Type: ApplicationFiled: December 19, 2024Publication date: July 10, 2025Inventor: Wesley Bryant Williams

Publication number: 20250083235Abstract: A workpiece-depowdering method and apparatus are provided. In another aspect, a method includes: robotically gripping an additively manufactured workpiece within an enclosure; and automatically blowing gas onto the additively manufactured workpiece to remove extra powder from the additively manufactured workpiece. A further method includes: additively layering powder within an additive manufacturing station, moving the additively manufactured workpiece to a depowdering station; holding the additively manufactured workpiece adjacent to the at least one nozzle with an automatically controlled gripper within the depowdering station; and depowdering the additively manufactured workpiece in the depowdering station by the gas. Another aspect provides a machine including: a robot configured to grip a workpiece; and a nozzle configured to blow excess powder off of the workpiece.Type: ApplicationFiled: April 10, 2024Publication date: March 13, 2025Applicant: AZOTH INC.Inventors: Mattia FORGIARINI, Cody COCHRAN, Christopher Bryant Williams

Patent number: 10850956Abstract: A handheld device is adapted to ascend and descend a cable. The handheld device includes a motor that is mechanically coupled to a gearbox shaft. A drive shaft is connected to the gearbox shaft with shaft drive bearings. A first housing is mechanically coupled to the motor and surrounding the drive shaft. The housing further includes a top side, a bottom side and at least one other side therebetween. A top housing opening and a side housing opening are arranged on the first housing. A cinch brake assembly, connected to the first housing. The cable is fed through the first housing, around the drive shaft, out of the first housing and through the cinch brake assembly such that the cinch brake assembly prevents movement of the cable through the first housing.Type: GrantFiled: April 8, 2020Date of Patent: December 1, 2020Inventors: Bryant William Bertrand, Marc Gonfiotti
