  • Patent number: 5881397
    Abstract: A bathtub drain closure having a strainer element with an internally threaded recess that engages male threads on the lower end of an upwardly extending post. The post has at least one transverse passageway containing a polymeric pin having ends that project slightly beyond the ends of the passageway. A stopper having a centrally disposed, internal bore slides up and down the post between open and closed positions. The central bore of the stopper has a stepped profile having upper and lower portions with an internal diameter slightly greater than the length of the polymeric pin and a middle portion with an internal diameter slightly less than the length of the polymeric pin, thereby causing the pin to be compressed into frictional engagement with the central bore as the stopper slides up and down between the open and closed positions.

  • Patent number: 5878472
    Abstract: A tool for and method to facilitate the replacement of wheels on track-and-wheel vehicles and equipment by lifting the track from the road-wheels in a quick, safe and efficient manner. A tool with an elongated section and two forked ends, each fork having a long prong and a short prong, the long prongs of both ends not being on the same side of the tool. In operation, one forked end is placed in notches in the lower track, and the other forked end is placed in notches in the upper track. The vehicle is then driven in a direction so that the tool acts as a wedge lifting the upper track off of the road wheel.

  • Patent number: 5848939
    Abstract: A free standing coin operated game system includes a computer and a mechanical animal for a player to ride. The game further includes a first video display screen displaying computer generated video graphics of a moving head section of an animal of the same species as the mechanical animal. The first screen is disposed in front of the mechanical animal and viewable by the player. A second video display screen displays the score of the player. A third video display screen displays computer generated video graphics of an animal of the same species as the mechanical animal and a mounted rider on the animal. During play of the game, movement of the head section image in relation to the surrounding arena images creates a sensation of movement in the player. The video graphics image displayed on the first video display screen induces physical movement by the player who is positioned on the back of the mechanical bull.

  • Patent number: 5810775
    Abstract: A cap operated retractable medical device has an outer body with a hingedly connected outer cap which moves between an open and a closed position. The device is used as a blood sampler with a conventional collection tube normally used in such devices. A movable member is entirely enclosed within the outer body. A sliding interference or friction fit holds a retraction body within the mouth of the movable member and also holds the front end of the movable member within the outer body positioned with the retraction body adjacent a stop. A double ended needle is installed in the retraction body. Camming protrusions on the cap engage the back of the movable member to move it forward as the cap is closed thereby triggering retraction of the retraction body and its double ended needle entirely within the outer body. Once the cap is closed with the double ended needle safely inside, the device can be safely handled. The device is compact. It can be as short as the needles it will safely contain.
