Abstract: The invention relates to the use of a polyolefin film as a medium to be written or printed on, according to which oxygen-containing groups are attached to one or both faces of the film surface by surface treatment. The polyolefin film is then highly surface-polarized by subsequently electrostatically charging it. Film thickness and surface weight and the electrostatic adhesive force produced are controlled by the degree of surface polarization in such a manner that the film, at least when the treated face is placed on a clean, dry and planar floatglass surface, will adhere to said surface indefinitely.

Title: Quasi-cw diode-pumped, solid-state uv laser system and method employing same
Inventor: SUN YUNLONG
IPC: H05K3/00
Filed: 2002-03-12
Abstract: A quasi-CW diode- or lamp-pumped, A-O Q-switched solid-state UV laser system (10) synchronizes timing of the quasi-CW pumping with movement of the positioning system (36) to reduce pumping while the positioning system (36) is moving from one target area (31) to the next target area (31) to form multiple vias in a substrate at a high throughput. Thus, the available UV power for via formation is higher even though the average pumping power to the laser medium (16), and thermal loading of the laser pumping diodes (14), remains the same as that currently available through conventional CW pumping with conventionally available laser pumping diodes (14). The quasi-CW pumping current profile can be further modified to realize a preferred UV pulse amplitude profile.

IPC: A63F3/06
Filed: 2002-07-08
Abstract: A computerized lottery or wagering system includes a game generator and a plurality of vendor stations that permit players to select game parameters. The game is graphically portrayed in animation as one or more races (horse race, dog race, car race, motorcycle race, etc.). The game may entail win, place, show, quinella, exacta/perfecta, trifecta, or series bets. At a predetermined time for each game, selection of game parameters for that game is ended and a winning sequence of numbers is randomly generated. The game generator selects and seamlessly composes a plurality of video segments into an animated video sequence of the race(s) corresponding to the winning sequence of numbers, for broadcast via RF transmission, microwave transmission, fibre optic cabling or closed circuit television lines. The video segments are rendered directly to a compressed digital format to maintain the video image in the highest quality possible. The system determines which players are eligible for a grand prize, and, after the game is shown, announces the grand prize winner. The games are generated and broadcasted periodically, e.g., one-per-minute, once-per-day, once-per-week, etc.

Filed: 1998-08-28
Abstract: A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a tap, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter-changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0.5-10° to the vertical, and preferably substantially continuous.      Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.
