Patent number: 11857994Abstract: A crossover prevention valve for use in a multi-component fluid mixing and dispensing system includes a valve body defining at least two fluid passageways having respective one-way check valves at their outlet ends. A forward end of the valve body cooperates with an interior surface of a dispensing nozzle to define a mixing chamber for chemically reactive fluids prior to discharging the mixed fluids out of the dispensing nozzle. The crossover prevention valve does not permit reverse flow, thereby preventing clogs due to undesired intrusion of one reactant into the flow path of another reactant. Solidified reactants left in the mixing chamber are easily removed from the valve body, permitting the valve body to be reused even after sitting for extended periods.Type: GrantFiled: May 4, 2020Date of Patent: January 2, 2024Inventor: Gary M.

Patent number: 11858035Abstract: Proposed is an electromagnetic vibration stirring device of semi-solid high pressure casting equipment. The electromagnetic vibration stirring device includes: a ring-shaped casing including an inner wall into which a sleeve is inserted and an outer wall spaced apart from the inner wall; and a magnetic field generating unit located between the inner wall and the outer wall of the casing, and including a plurality of electromagnets radially arranged at equal intervals around the sleeve in a circumferential direction of the sleeve, each of the electromagnets including a core and a coil surrounding the core. The magnetic field generating unit generates a magnetic field by applying a current to the electromagnets in a clockwise or counterclockwise direction, and each portion of a semi-solid molten metal is sequentially vibrated by the magnetic field along the circumferential direction of the sleeve, thereby controlling a microstructure of the molten metal.Type: GrantFiled: February 28, 2023Date of Patent: January 2, 2024Assignee: HANJOOMETAL CO., LTDInventors: Yong Jin Lee, Jin Ha Park, Seong Rak Park, Joong Suk Roh, Hee Jae Bang

Patent number: 11858036Abstract: A system and method for filling a mold with molten aluminum includes a molten metal pump, a vessel configured to contain molten metal, a mold for receiving molten metal, and a conduit between the vessel and the mold. Molten metal is pumped in the vessel until it reaches a level at which it flows through the conduit and into the mold. The flow of molten metal into the mold is stabilized to maintain a level of molten metal in the mold. A skin of solid metal forms between the mold and the conduit, at which time the pumping of molten metal can cease. The mold with solid metal in it can be moved.Type: GrantFiled: May 18, 2020Date of Patent: January 2, 2024Assignee: Molten Metal Equipment Innovations, LLCInventor: Paul V. Cooper

Patent number: 11858037Abstract: A smart molten metal pump system and method automatically controls the operating speed of the pump rather than requiring an operator to control the speed. The system includes a pump, a controller for controlling the speed of the pump and one or more vibration sensors (such as an accelerometer) to measure vibration. The controller receives input about the vibration of the pump or one or more pump components, and possibly other data, such as the temperature of the molten metal, and/or the depth of the molten metal, ad/or parameters related to the operation of the pump. The controller analyzes the one or more inputs to vary the speed of the pump, turn the pump off, and/or send a communication to an operator.Type: GrantFiled: September 7, 2022Date of Patent: January 2, 2024Assignee: Molten Metal Equipment Innovations, LLCInventors: Vince Fontana, James Robert Daniels

Patent number: 11858038Abstract: A process for the additive manufacture of a metallic and/or vitreous and/or ceramic component, a mixture of substrate particles and an at least two-phase binder is firstly provided. The mixture is preferably provided as composite particles, so that the substrate particles adhere to one another by the at least two-phase binder. The mixture is selectively melted layerwise by electromagnetic radiation so that a shaped part is additively produced. The shaped part is taken out from the mixture which has not been melted and the at least two-phase binder is subsequently removed, preferably successively. The process produces a microporous shaped part which after sintering leads to a component having a desired density and a desired mechanical and/or thermal stability.Type: GrantFiled: March 2, 2018Date of Patent: January 2, 2024Assignee: SKZ-KFE gGmbHInventors: Christian Fischer, Christian Staudigel

Patent number: 11858040Abstract: Disclosed are a method of inspecting a printing quality of a 3D printing object using a femtosecond laser beam during a 3D printing process, and an apparatus and a 3D printing system for the same. A laser beam is irradiated from a femtosecond laser source disposed coaxially with a 3D printing laser source to inspect a state of the printing object. The laser beam generated by the femtosecond laser source is separated into a pump laser beam and a probe laser beam. The printing laser beam irradiated from a 3D printing laser source or the pump laser beam is irradiated onto a printing object to generate ultrasonic waves. To measure the ultrasonic waves, a probe laser beam is irradiated onto the printing object. The probe laser beam reflected by the printing object is detected. The quality of the printing object is inspected by analyzing the reflected probe laser beam.Type: GrantFiled: December 21, 2020Date of Patent: January 2, 2024Assignee: Korea Advanced Institute of Science and TechnologyInventors: Hoon Sohn, Peipei Liu
