  • Poppet valve for an internal combustion engine
    Patent number: 10760455
    Abstract: A poppet valve has an elongated stem that is configured to extend along a longitudinal axis. The poppet valve further includes a valve body that is disposed laterally with respect to the longitudinal axis and located in a spaced apart relation with an end of the elongated stem. The valve body has a pair of opposing faces disposed co-axial with the longitudinal axis of the elongated stem. The poppet valve also includes at least two arcuately shaped appendages depending downwardly from the end of the elongated stem and extending away from the longitudinal axis of the elongated stem. An end of each appendage is disposed in abutment with an annular region defined on one of the opposing faces of the valve body, a perimeter of the annular region being larger than a perimeter of the elongated stem measured about the longitudinal axis.

  • System and method for evaluating additive manufacturing index
    Patent number: 10611086
    Abstract: A method for evaluating part for additive manufacturing is provided. The method includes receiving data related to a set of printability factors associated with the part. The set of printability factors comprise at least: an availability of a three dimensional printer, a build density, a fraction of part to be printed, a print accuracy, a part complexity, and a number of parts needed. The method includes evaluating a printability index associated with the part based on at least three printability factors from the set of printability factors. Further, the method includes displaying the printability index associated with the part for the evaluation of the part for additive manufacturing.
