  • Patent number: 6592454
    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, fiber 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.

  • Patent number: 6568616
    Abstract: A condiment grinder includes a housing, a chamber within or attached to the housing for containing articles to the ground such as pepper seeds. A trigger is attached to the housing. An elongate piston extends through the chamber and has serrations along a portion of its length. A linkage co-operates with the trigger and the piston to transmit reciprocal movement of the trigger to reciprocal movement of the piston. A grinding aperture adjacent to the chamber has an internal periphery and is co-operative throughout its internal periphery with the serrations of the piston to grind the articles upon reciprocation of the piston.

  • Patent number: 6458159
    Abstract: The invention provides a spinal disc implant comprising two side walls which are opposed and substantially parallel spaced apart by a front wall and a back wall to define an interior space. The side walls define substantially elliptical curves joining the front and back walls. The front wall is also curved and the back wall may be either curved or straight. The walls may have openings or holes which may be circular or elliptical in shape. The upper and lower edges of the implant have a plurality of teeth extending therefrom for engaging adjacent vertebrae. The implant is made of a biocompatible metal such as titanium or an alloy thereof, and the first and second sides tapering from the second end to the first end. The interior space has a porous hydroxyapatite block shaped to fill the interior space. The porous hydroxyapatite substance helps the prosthesis integrate into the vertebral structure by allowing into the pores.

  • Patent number: 6406751
    Abstract: In the paper coating operation a wet or dry edge from coating composition is formed on the, seen in the direction of movement of the paper web, downstream side of the doctor, the so-called stalagmite formation. This stalagmite formation leads to various problems in the papermaking process and especially occurs at high speeds of the paper web and/or a high solids content of the coating composition, which two operating conditions are exactly required to obtain a maximum paper yield and a high paper quality. According to the invention the stalagmite formation is effectively prevented by supplying a fluid inhibiting the stalagmite formation to an area bounded, on the one hand, by the paper web and, on the other hand, by the above side of the doctor blade.
