  • Methods for casting by a float process and associated apparatuses
    Patent number: 9050652
    Abstract: A method for producing a solid layer material (42), comprising providing (70) a first layer (30); providing (72) a second liquid layer (32) on the first layer (30); providing (74) a third liquid layer (34) on the second liquid layer (32), wherein the third liquid layer has a melting point that is higher than a melting point of the second liquid layer, and wherein the second liquid layer is between the first and third layers; cooling (76) a surface of the third liquid layer to a temperature less than the melting point of the third liquid layer; forming (78) the solid layer from the third liquid layer while cooling the third layer liquid; and removing (80) the solid layer.
    Type: Grant

  • Apparatuses, systems, and methods utilizing adaptive control
    Patent number: 8095227
    Abstract: A method for controlling a process, wherein the process has an input and an output, and including controlling the input to the process; predicting the output of the process based on a first set of operating parameters; predicting the output of the process based on a second set of operating parameters; updating the first set of operating parameters when a result from predicting the output from the first set of parameters differs from the output of the process by more than a predetermined amount, wherein the predetermined amount is a function the output predicted by the second set of parameters. The invention also includes apparatuses and systems.
