Patent number: 6779455Abstract: The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.Type: GrantFiled: March 27, 2003Date of Patent: August 24, 2004Assignee: Creo Il Ltd.Inventors: Murray Figov, Anna Sigalov

Publication number: 20040144650Abstract: Method of synthesis of confined colloidal crystals using electrodeposition. The present invention provides a method of growing confined colloidal crystal structures using electrodeposition of monodispersed charged colloid spheres onto a substrate patterned with an array of electroconductive surface relief features on a surface of a substrate. In this approach, control over large-scale ordering is achieved via a planar pattern whose scale is on the order of tens of microns, a regime readily accessed through coarse lithography, laser micromachining, and holography.Type: ApplicationFiled: January 29, 2003Publication date: July 29, 2004Inventors: Eugenia Kumacheva, Edward H. Sargent, Robert Kori Golding, Mathieu Allard

Patent number: 6755950Abstract: An improved electrocoagulation printing method is disclosed. A plurality of dots of colored, coagulated colloid representative of a desired image are formed on a moving, olefin-coated surface of a positive electrode, by electrocoagulation of a colloid present in an electrocoagulation printing ink filling an electrode gap defined between a positive electrode and a plurality of negative electrodes. The improvement comprises applying to selected negative electrodes a trigger signal of a voltage sufficient to energize same and cause point-by-point selective coagulation and adherence of the colloid onto the positive electrode surface opposite the surfaces of the energized electrodes. The trigger signal comprises at least two consecutive pulses having the aforesaid voltage and a predetermined pulse duration with a time interval therebetween at least as long as the pulse duration, thereby increasing the optical density of each dot and of the resulting image.Type: GrantFiled: April 11, 2002Date of Patent: June 29, 2004Assignee: Elcorsy Technology Inc.Inventor: Adrien Castegnier

Publication number: 20040026249Abstract: A method and apparatus for the spatial distribution of a filler component within the matrix of a composite material are disclosed. An electric field is applied to a mixture consisting of two or more components that have different dielectric permittivities, at least one of which is initially in the form of a liquid polymer or pre-polymer. An alternating electric field is established between a pair of electrical conductors or electrodes that are moved relative to each other, so as to alter the spatial intensity of the electric field in a controlled manner. Polarized particles or elements of the filler component that are coupled to a moving electrode by a dielectrophoretic force can consequently be dragged into a predetermined spatial configuration. As the size of the inter-electrode gap is changed, the applied voltage can be adjusted in order to maintain electrically induced polarization of the filler component.Type: ApplicationFiled: October 10, 2002Publication date: February 12, 2004Inventors: Roger W Whatmore, Steve A Wilson

Publication number: 20030178307Abstract: The present invention provides methods for producing hollow ceramic membranes by electrophoretic deposition. The hollow ceramic membranes may have a small cross-sectional area of about 1.0×10−5 mm2 to about 25 mm2. The cross-sectional configuration of the hollow ceramic membranes may be any geometry such as circular, square, rectangular, triangular or polygonal. The hollow ceramic membranes produced by the methods of the present invention may have multiple layers but always the innermost layer, or the first deposited layer is porous and made by electrophoretic deposition. Subsequent layers may be porous or non porous and deposited before or after sintering the first layer. If it is deposited after sintering, it may require additional sintering steps. Additional layers may be deposited by further electrophoretic deposition, sol-gel coating, dip coating, vacuum casting, brushing, spraying or other known techniques.Type: ApplicationFiled: May 5, 2003Publication date: September 25, 2003Inventor: Partha SARKAR
