Abstract: A solution for concealing confidential information that is printed at the point of sale in a game of chance utilizing a more common type printer designed for printing on a standard grade and biodegradable direct thermal paper. This system can print and cut each individual ticket in variable lengths. The unique and innovative concept of this new system allows a second and separate biodegradable substrate to be collated in a continuous stream over top of the printed ribbon before it is cut away and delivered into the presenter. The second substrate contains a strip of a specially formulated adhesive and is adhered to the top surface of the printed ribbon as the two substrates join together while passing through mechanical nip rollers. The confidential printed information is now covered and the combined substrates are cut and delivered as one ticket unit. The ticket information is revealed by easily peeling away the adhered top layer.

Abstract: A compact Selective Catalytic Reduction (SCR) system comprising a gas flow inlet system, a vaporizer module and an SCR reactor is described. The inlet flow system is configured to provide heat to the vaporizer module, to mix reductant with the exhaust gas and to provide an approximately uniform flow of the exhaust gas through the catalyst. The vaporizer module is configured to vaporize reductant from a solution of a reductant or a precursor of a reductant and to transfer the vaporized reductant into the gas flow inlet system, where it is mixed with exhaust gas. The SCR reactor contains and SCR catalyst is in fluid communication with the inlet flow system and the vaporizer module.

Abstract: The present invention relates to printing inks for the intaglio printing process, also referred to as engraved steel die printing process. In particular, oxidatively curing inks comprising a combination of fusible wax and a UV curing binder component are disclosed. These inks can be printed on a standard printing press, and, through a short UV irradiation after printing, allow to significantly reduce or eliminate the undesired set-off which can occur after printing and stacking the printed sheets. Using the inks of the present invention results in less set-off contaminated printed sheets, allowing for a higher pile-stacking of the printed good, for the use of increased engraving depths, of a more challenging intaglio design, and for the printing on less porous substrates, while enabling the printing on a standard printing press, and offering the possibility of using a lower printing plate temperature.

Abstract: Multi-layer, edge ingress, tamper- and solvent-indicating labels comprise a top film layer coated over a solvent, e.g., water, hydrocarbon, etc., and dye absorbing layer. The solvent and dye absorbing layer can be on top of a porous layer comprising a binder, pigment and particles of a solvent-soluble dye. The porous layer can be on top of an edge-wicking layer which itself is on top of a pressure-sensitive adhesive (PSA) layer. The edge-wicking layer both absorbs and transports solvent thus serving as a means for transporting solvent to the solvent-soluble dye.

The graphic and/or message display system functions to develop over a period of time a hidden graphic or message on an indicator panel or display area. The hidden graphic or message is revealed when an obscuring graphic reacts with a solvent to change color become at least substantially transparent. The graphic and/or message display system may be used as a stand-alone device or may be incorporated as part of various articles or products, for instance, as a positive reinforcement or a reminder to perform a task. Methods for using the graphic and/or message display system are also described.

Abstract: Tamper evident forms are provided having a transparent layer bonded to a scrambling layer. One or more coating layers may be disposed on the surface of the transparent laminar. Printed indicia on the upper surface of the form is not readable unless the transparent lamina is physically separated from the scrambling layer or if the scrambling layer is optically altered or negated. The coating layers may reveal tamper evidence if a surreptitious attempt of obtaining the printed indicia is made by physical, mechanical, electronic and/or chemical means without removing the separating the transparent lamina and the scrambling layer.

Abstract: A method of identifying an object comprising providing an vehicle having on a surface thereof at least one layer of paint, such as a urethane-based paint. A unique alphanumeric identification is applied to the paint layer with a fluorescent material at a selected unrevealed location thereon. The fluorescent material is permitted to migrate into the at least one paint layer, while an excess amount of fluorescent material remains on the at least one paint layer. Thereupon, the excess amount of fluorescent material is removed from the at least one paint layer with a solvent. The unique discrete identification created by fluorescent material migrated into the at least one paint layer is visible at an acute angle to the object surface without use of an ultraviolet light, while being substantially invisible at an angle normal to the object surface.

Abstract: A latent image is formed by applying a colorless liquid that makes colorants of ink insoluble to a predetermined area of a print material. The latent image is made visible by applying ink to only the predetermined area of the print material to cause reaction between the ink and the colorless liquid to make the colorants of the ink insoluble and thereby fix the colorants in the print material. Another method of making a latent image visible involves applying ink to the entire surface of the print material and washing the print material with water to remove unfixed ink.

Abstract: A counterfeit-resistant document comprises a validation mark with a unique chemical signature that identifies the source of the document. The source of the document can be identified by detecting the unique chemical signature on the validation mark of the document, thus verifying the authenticity of the document. The unique chemical signature is applied to the document as ink, so that the validation mark provides information. The validation mark is latent in that the color of the coating matches that of the document, but the directional reflective properties of ink is more uniform than that of the document. In this manner, the letters cannot be readily ascertained by viewing them at an angle perpendicular to the surface of the document, but can be readily ascertained by viewing them at an angle different from that perpendicular to the surface of the document.

Abstract: A business document contains a removable decal. The decal has a plastic substrate overlaid with a reflective coating including an aluminum coating and glass beads. A toner receptor coating overlies the reflective coating. A fine screen pattern is printed on the toner coating and which pattern may include jagged lines or closely spaced dots. Variable and non-variable information is then printed on the toner receptive coating. In the event of use of a solvent to alter the printed information on the decal, the fine printed screen pattern is likewise disrupted and evidences alteration of the decal.
