Patent number: 10076784Abstract: A liquid containing receptacle having a filter is disclosed that in one form includes a nozzle. The filter includes a passage having a portion with a size that restricts the flow of a liquid there through unless sufficient pressure is applied to overcome a liquid and filter property such as surface tension. The pressure in the liquid at the filter can be varied by changing a gas overpressure above a surface of the liquid, changing a head height of the liquid, and/or changing the liquid and filter property, among possible others. In one embodiment the liquid containing receptacle can be used to contain a molten metal that is used in an investment casting mold. The molten metal can be selectively poured into a mold by selectively changing pressure of the molten metal at the filter or by changing the pressure at which molten metal flows through the filter.Type: GrantFiled: December 15, 2014Date of Patent: September 18, 2018Assignee: Rolls-Royce CorporationInventors: Paul Anthony Withey, Max Eric Schlienger

Patent number: 8961858Abstract: There is disclosed stereolithographic manufacture of more complex components including at least one active material without the need for fabrication. Fabrication can introduce component discontinuities that hinder performance of the final component. Thus, some embodiments entail a method of manufacture for complex, field activated components such as piezoelectric or magnetostrictive sensors or actuators.Type: GrantFiled: April 14, 2009Date of Patent: February 24, 2015Assignee: Rolls-Royce CorporationInventors: Paul Anthony Withey, Max Eric Schlienger

Patent number: 8752610Abstract: A method includes providing a mold including a molten casting material, moving the mold in a first direction, and guiding a solidification interface across the mold in a second direction in response to the moving the mold. The second direction is deviated from the first direction, and the solidification interface includes a transition to a negative heat transfer region. The mold moves in the first direction at a constant speed, and the mold includes heat transfer features such that a solidification time of the molten casting material at the conditions of the solidification interface is approximately constant as a function of the second direction.Type: GrantFiled: August 9, 2010Date of Patent: June 17, 2014Assignee: Rolls-Royce CorporationInventors: Max Eric Schlienger, Paul Anthony Withey

Patent number: 8743340Abstract: A system is disclosed including an image sensor positioned at a first specified angle relative to a projected image plane. The system includes a projector that projects a test pattern onto the projected image plane. A controller is structured to iteratively adjust the projector focus until an image focus index is maximized, where the image focus index is a function of an amplitude of at least one harmonic frequency of a scan of the test pattern. The controller is further structured to determine a skew indicator value and adjust a projector skew adjustment. The controller is further structured to compare a current zoom level to a target zoom level and adjust a projector zoom. The projected image plane is a manufacturing surface, where the projected image is utilized in a manufacturing process.Type: GrantFiled: December 29, 2009Date of Patent: June 3, 2014Assignee: Rolls-Royce CorporationInventors: Max Eric Schlienger, Paul Anthony Withey

Patent number: 8501085Abstract: An apparatus for bottom pouring into an investment cast includes a container that holds a melted casting material, where the container moves from a first container position to a second container position. In the first container position, holes on a stationary nozzle are not exposed to the interior of the container, and the melted casting material remains in the container. In the second container position, holes on the stationary nozzle are exposed to the interior of the container, and the melted casting material flows out the bottom of the container through the stationary nozzle. A temperature detection device determines the temperature of the melted casting material, and a heating device heats the melted casting material to a specified temperature.Type: GrantFiled: August 9, 2010Date of Patent: August 6, 2013Assignee: Rolls Royce CorporationInventors: Max Eric Schlienger, John Sylvester Torpey, Paul Anthony Withey

Patent number: 8083987Abstract: A method of initiating a pour of a liquid alloy comprises the steps of filling an interior of a crucible with a displacement plunger and the liquid alloy until a metal head of the liquid alloy exceeds a critical height. The crucible has a bottom pour opening with a plug inserted therein. The plug is configured to be buoyant within the liquid alloy when the liquid alloy is below the critical height. Pour is initiated by at least partially withdrawing the displacement plunger until the metal head drops below the critical height.Type: GrantFiled: April 14, 2009Date of Patent: December 27, 2011Assignee: Rolls-Royce CorporationInventors: Max Eric Schlienger, Paul Anthony Withey
