Patent number: 11293682Abstract: Methods and apparatuses for transferring heat to and from multiple objects. Such a method entails placing objects in a vessel that contains a heat transfer fluid so that the objects contact the heat transfer fluid. The heat transfer fluid is at a temperature that is different from the temperature of the object, and is induced to circulate along a continuous flowpath. Each object is at least partially disposed in the flowpath of the heat transfer fluid, and each object is individually rotated about an axis of rotation thereof. The heat transfer fluid continues to circulate and the objects continue to rotate for a time sufficient to cause the temperatures of the objects to become closer to the heat transfer fluid temperature.Type: GrantFiled: April 26, 2019Date of Patent: April 5, 2022Assignee: Purdue Research FoundationInventors: Mitchell Anthony LoVerde, David Stephen Page, Kyle Chang Ma, Scott Robert Lancaster, Christopher James Mead

Pneumatically adjustable apparatus for coating toner fusing belt substrate and method for using same
Patent number: 7560140Abstract: An apparatus for enabling the uniform application of a layer of a coating composition to a tubular substrate includes a shaft, and upper and lower circular rim members of equal diameter that are concentrically attached to the shaft. A pneumatically inflatable tube disposed on each circular rim member has an outer diameter that is variable with changes in its internal pressure. A first flexible cylindrical sheet in contact with the inflatable tubes has parallel edges that form a first slit sufficiently wide to permit movement of the first sheet in response to pressure variation in the tubes. A second flexible cylindrical sheet surrounding the first cylindrical sheet has parallel edges that form a second slit sufficiently wide to permit movement of the second sheet also in response to pressure variation. The second slit is laterally displaced from the first slit, and the second cylindrical sheet has a diameter nearly equal to the specified diameter of the substrate.Type: GrantFiled: October 3, 2008Date of Patent: July 14, 2009Assignee: Eastman Kodak CompanyInventors: Jiann-Hsing Chen, Robert A.
