  • Additive manufacture from machined surface
    Patent number: 10207325
    Abstract: A method of additive manufacturing includes building a component having a top surface, attaching the component to a powder bed fusion plate that receives the component, filling the powder bed fusion chamber so the powder is flush with the top surface of the component, and adding a first layer of powdered metal level with the top surface of the component. The method of additive manufacturing also includes fusing the first layer of powdered metal to the top surface of the component to create a fusion joint, and building up an additively manufactured body from the top surface of the component in subsequent layers.
    Type: Grant

  • Fuel injection and mixing systems having piezoelectric elements and methods of using the same
    Patent number: 8074895
    Abstract: A fuel injection and mixing system is provided that is suitable for use with various types of fuel reformers. Preferably, the system includes a piezoelectric injector for delivering atomized fuel, a gas swirler, such as a steam swirler and/or an air swirler, a mixing chamber and a flow mixing device. The system utilizes ultrasonic vibrations to achieve fuel atomization. The fuel injection and mixing system can be used with a variety of fuel reformers and fuel cells, such as SOFC fuel cells.
