Abstract: A game resembling a maze is disclosed. The game is formed of a substrate onto which distinct grids are printed, each containing multiple numerals or other suitable symbols. Opaque coatings cover both grids, concealing the symbols printed on the substrate, and adjacent boxes of one grid create multiple pathways from one border of the grid to another. In use, a player removes selected portions of the opaque coatings to determine whether adjacent boxes containing certain exposed symbols form a continuous path connecting separate borders of the grid.

Abstract: Structures for items such as promotional materials, game pieces, lottery tickets, security documents and other articles, which feature one or more thermal reactive layers that are activated by heat from a hidden image formed of infrared sensitive, heat generating material such as carbon black preprinted under the thermal reactive layers during manufacture. The thermal reactive layers permit transmission of radiant energy such as infrared to the heat generating, hidden layers. The heated image conducts heat to the thermal reactive layers which employ a coloring agent and a developer which, when exposed to the heat, react or act in concert in order to form a corresponding image on the face of the item.

Abstract: Packages for sets of promotional or other articles (such as lottery tickets or coupons) which conceal information included on the articles, and methods of forming the packages, are disclosed. Embodiments of the package include even (or odd) numbers of integrated panels of equal size, pairs of which panels are separated by fold lines. A four-panel package may be folded along the first and third fold lines so that the inner face of each panel contacts the inner face of an adjacent panel. The package then may be folded along the second fold line so that the exposed outer faces of the remotest panels contact, thereby forming a package having the length and width of a single panel. Sets of tickets or articles equal to the number of panels (or multiples thereof) may then be formed simultaneously by creating areas in the folded package completely defined by lines of weakness.

Abstract: Methods and apparatus for printing and collating multiple webs of materials, particularly for use in creating personalized direct mail materials, are disclosed. The invention includes a single, highly flexible press having components capable of being driven at unequal speeds to account for different sizes of insert materials and their associated envelopes. Operating a single press in this manner reduces the amount of waste web material which otherwise would be present. The press similarly includes novel collating and inserting apparatus whereby each outgoing envelope is effectively formed around the "insertable" materials. Control mechanisms and verification systems associated with the press additionally maintain any personalized materials in registration, permitting a single press to produce the entire direct mail piece from multiple webs with minimal waste.
