  • Patent number: 5603502
    Abstract: A poker tournament commences with first groups of several or more players playing poker games at different tables. The players are initially provided with a certain number of game chips for use in the games. When players lose their chips, they drop out of the tournament games. When the total number of players remaining in the games declines to a specific number (which is an exponential product of the number two), they are matched up into pairs each playing in individual one-on-one games. The winners of the individual games are rematched with other winners into pairs and this rematching successively continues until one player has won all of the chips in the tournament.

  • Patent number: 5167453
    Abstract: A recorder is disclosed for producing a continuous data record and comprises a case, a strip chart which is wound from a chart storage compartment onto a spring-driven take-up spool, and a speed-reducing governor comprising a gear train which is operatively connected to a hub and spoke assembly immersed in small spheres or balls, preferably of environmentally impervious material such as glass. The sphere-immersed paddle wheel approximates the drag of viscous fluid systems, with advantages which include independence of drag characteristics from temperature variation, simplicity, and easy speed adjustment, that is, the size of the spheres can be used to change the speed of the recorder.

  • Patent number: 4755063
    Abstract: A recorder is disclosed for producing a continuous data record and comprises a case, a strip chart which is wound from a chart storage compartment onto a spring-given take-up spool and a speed-reducing governor comprising a paddle wheel, immersed in viscous fluid, operatively connected to the driven take-up spool by a gear train. The paddle wheel contains temperature-responsive paddles which extend or retract in response to increases and decreases in the temperature to compensate viscosity changes in the fluid. Also, the drive spring is mounted within the take-up spool inside a free-rotating sleeve which prevents spring distortions from interfering with the smooth operation of the take-up spool.

  • Patent number: 4253617
    Abstract: A speed governor for a disposable spring motor driven data recorder of the type which is used, for example, in a railroad car to graphically record, on a traveling tape, the temperature in the car at all times during a transit period of several days; the speed governor comprising a mechanical-hydraulic mechanism associated with the spring motor and operative to control--to a constant but extremely slow rate--the speed of travel of the tape.

  • Patent number: 4007637
    Abstract: A temperature recorder which produces a continuous graphic record, scribed on a removable tape, of the temperature existing in an enclosure (such as a refrigerated railroad car) during a given period of time (e.g., the transit time of such a railroad car). The present temperature recorder--which is a modification, in disposable form, of the recorder for like purpose shown in U.S. Pat. No. 3,826,140, dated July 30, 1974-- comprises, in a sealed case, a slow travelling tape which spans between a tape feed spool an a spring-driven tape take-up spool; there being a temperature-responsive device which scribes--in terms of temperature in relation to time--on the tape as it so travels, and means to regulate the speed of travel of said tape.
