Patent number: 8313708Abstract: An apparatus for treating objects with a treatment gas comprises a treatment chamber, a chamber input through which objects enter the treatment chamber, and a chamber output (which may be the same as the chamber input) through which the objects leave the treatment chamber. The treatment chamber encloses the treatment gas, which can be steam. The chamber output and/or the chamber input include an intermediate medium, such as a liquid, through which the objects pass. The intermediate medium prevents escape of the treatment gas from the treatment chamber and the ingress of external gases into the treatment chamber, while facilitating input of the objects to the chamber, and output of the objects from the chamber.Type: GrantFiled: February 17, 2005Date of Patent: November 20, 2012Assignee: The Penn State Research FoundationInventor: Paul N. Walker

Patent number: 6457513Abstract: The present invention is a segmented flow device for performing the functions of a reactor, heat exchanger or holding tube or their combination. The device controls the residence time of all of liquid and solid particles which make up a flow in the device. By controlling the residence time, the prediction of residence time becomes less of an issue during processing. The segmented flow device reduces the difference in residence time between the fastest and slowest moving particles of the flow. The device allows all of the particles to receive nearly the same processing time to reduce under-processing or over-processing of the particles If desired, the device allows the residence time of the larger solid particles to be controlled to be longer or shorter than the average of the residence time of other particles of the flow, such as the liquid and smaller solid particles.Type: GrantFiled: August 3, 2000Date of Patent: October 1, 2002Assignee: The Penn State Research FoundationInventor: Paul N.
