  • Patent number: 6669530
    Abstract: A multi-purpose projecting device for propelling and disseminating, generally vertically, paper disks, confetti, or fluid contained in a cartridge. Contents of the cartridge as well as the outside surface of the launching tube may be covered with a fluorescent material. The launching tube may serve as a flagpole to supplement its primary function at large social gatherings such as sporting or music events, wedding ceremonies, holiday celebrations, etc. The device consists of a two-part cylindrical launching apparatus and a cylindrical cartridge that may hold paper disks, confetti, fluid, or other soft materials such as fiber, string, fabric, etc. The upper section of the launching tube folds back, into which the cartridge can then be inserted. The lower section of the launching tube consists of a spring, a plunger, a spring, a string, and a trigger. After the cartridge is loaded, a string connecting to the plunger is pulled, contracting the spring and setting the trigger ready for launching.

  • Patent number: 6394135
    Abstract: There is a balanced plug valve with a contour shaped wall. The contour shaped wall forms a gap with an edge of a balanced plug. Fluid is able to flow through an input port, through the balanced plug, through the gap, and out an output port. The shape of the contour and the relative position of the balanced plug to the contour shaped wall affect the modulation of the rate of the fluid flow through the gap, and thus, through the valve. Multiple possible variations of the dimensions of the contour shaped wall make possible a multitude of flow rate verses valve stroke relationships. Further, the use of a balanced valve decreases friction forces on the plug which allows for smaller, more efficient, and more economical valve actuators.
