Patent number: 9017772Abstract: Various embodiments provide methods and apparatus for forming intermediate transfer belts (ITBs) by combining a dip-coating process with a UV-curing process. In an embodiment, an ITB substrate can be immersed into a liquid coating composition contained in a dip tank and then withdrawn from the liquid coating composition. When exiting the dip tank, the coated substrate can enter a UV-curing chamber for a UV-curing process. Multiple cycles of dip-coating and UV-curing can be performed such that a desired ITB substrate coating layer thickness can be obtained. After coating the ITB substrate, the UV-cured coating composition can be released from the ITB substrate, wherein the UV-cured coating composition released from the ITB substrate forms the intermediate transfer belt.Type: GrantFiled: July 8, 2010Date of Patent: April 28, 2015Assignee: Xerox CorporationInventors: Geoffrey M.

Patent number: 9011982Abstract: A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8?) selectively at selected positions of the layer. In the second step, the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step, a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18?) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.Type: GrantFiled: May 23, 2008Date of Patent: April 21, 2015Assignee: EOS GmbH Electro Optical SystemsInventors: Frank Muller, Andreas Pfister, Martin Leuterer, Peter Keller

Patent number: 8999507Abstract: The invention relates to a process for applying a liquid UV-curable primer sealant to natural stone tiles and related articles followed immediately by the exposure to a requisite amount of low intensity UVA-type UV radiation to partially cure the primer sealant. The partial curing, or pre-setting, of the primer sealant enables control of the ultimate depth of penetration of the primer sealer into the natural stone tiles and natural stone articles of which many examples are quite porous. Because the low level UV irradiation is instantaneous after the primer sealant application the level of primer sealant penetration into the natural stone surface is regulated. The pre-curing of the primer sealant is conducted to intentionally solidify or immobilize the sealant that has actually penetrated into the natural stone surface. The uppermost layers of the primer sealant are left in a semi-liquid or uncured state to allow for wetting and intermingling by the top sealant once it is applied.Type: GrantFiled: December 4, 2012Date of Patent: April 7, 2015Assignee: Questech CorporationInventors: David Pelletier, Roger Questel, Larry Wasowski, Dorian C.

Patent number: 8993042Abstract: A method to evaluate, determine and optimize production parameters for a coating application of a UV cationic polymerizable coating system to a substrate is provided. The method is based on a simulation model which includes both shadow and dark cure processes. Both of an active center generation process and the active center diffusion process are mathematically described. In the model, the two processes are considered separately since they are driven by different fundamental phenomena and occur on different timescales. Evaluation or prediction of the effect of process variables on the curing of a cationic coating of a complex substrate according to the described method allows characterization and understanding of process variables which may save set-up costs and improve production efficiency.Type: GrantFiled: January 6, 2010Date of Patent: March 31, 2015Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., University of Iowa Research FoundationInventors: Cynthia Gazepis Templeman, Alec B.
