  • Patent number: 6314910
    Abstract: A fish feeding mechanism that disburses fish food within a fish tank in metered quantities, allowing fish the time to consume the food before it settles. The feeding mechanism is affixed to the inside of the fish tank by a suction cup or a suspension hook and comprises a food container whose top end is positioned above the water surface. The submerged surface end of the food container includes at least one food outlet that opens into the fish tank. Adjacent to the food container and also submerged inside the fish tank is a lift tube provided with an inlet port to allow water from the fish tank to enter, while a channel in the lift tube allows the water to enter the food container. An air line is inserted into the lift tube's inlet port and the compressed air therefrom flows from the mouth of the air line and enters the lift tube, causing air bubbles to rise to create an upward current of water.

  • Patent number: 6296568
    Abstract: A video game complete with player wagering includes a processor and a display controlled by the processor. Said display is a game board in the form of a pyramid having an apex, a base and a plurality of pins displayed on the game board. Also displayed at the base is a plurality of locations each defining an outcome for the game. During play, a character is displayed falling from the apex to the base being directed by contact with the pins. The game payout is dependent upon the base location ultimately occupied by the character. In a preferred embodiment the pins can be programmed as stop pins, lateral shift pins or bonus pins. Upon contact with the character the stop pin will end the game with no payout, the lateral shift pin will move the character to the left or right and the bonus pin will cause a bonus payout.
