  • Reciprocating engine
    Patent number: 11732672
    Abstract: A reciprocating engine includes a crankshaft and a connecting rod rotatably coupled to the crankshaft. The connecting rod defines a fluid passage extending along a length thereof. The reciprocating engine also includes a piston dome coupled to the connecting rod, the piston dome defining an inlet in fluid communication with the fluid passage of the connecting rod for receiving a fluid from the fluid passage of the connecting rod, a cooling passage in fluid communication with the inlet for circulating the fluid through the piston dome, and an exit in fluid communication with the cooling passage.
    Type: Grant

  • SYSTEMS AND METHODS FOR ESTIMATING POWDER DOSING IN ADDITIVE MANUFACTURING PROCESSES
    Publication number: 20230256511
    Abstract: A method for forming a component includes estimating a dosing plan for powder of a powder bed fusion (PBF) system needed to form the component. The dosing plan includes powder dosing requirements needed per layer to form the component. The method includes providing the dosing plan to a controller of the PBF system. Further, the method includes regulating the powder being supplied to a build chamber of the PBF system from a supply chamber of the PBF system based on the dosing plan. In addition, the method includes additively manufacturing the component via the PBF system using the powder.
