Abstract: An aerial amusement projectile and method of manufacture, the projectile including an aerodynamic body having a streamer secured therein. The aerodynamic body is fabricated from a resilient, penetrable material and has an ornamental design on a leading face opposite the streamer. The streamer is fabricated from a plurality of multicolor ribbons and is secured inside the aerodynamic body by a novel fastener apparatus and method. The fastener may be fabricated as a U-shaped staple from a resilient wire with a pair of barbed probes or as a harpoon-like device to hold the streamer in the body. The configuration of the fastener and resiliency of the aerodynamic body material assists in securing the fastener against dislodgment from the body material. A padding member is mounted on the staple fastener to protect the streamer against abrasion. The harpoon-like fastener includes a coaxial, countersunk bore for receipt of an insertion tool.

Abstract: A two-stage hydraulic flush device for use in regulating the amount of water released when flushing a conventional water closet. The flush handle of a conventional water closet is actuated so as to unseat a drain plug in the water tank, and the piston of a hydraulic cylinder which is submersibly disposed within the water tank is then displaced to one of two distinct positions. As the piston is displaced, water is admitted into the cylinder below the piston. When the flush handle is released, water is expelled from the cylinder at a controlled rate as the piston is forcibly returned by a spring mechanism to its initial position. As the piston returns, the lifting arm is actuated so as to reseat the drain plug. The water outlet flow rate determines the duration of the flushing action, and two distinct piston positions define the two flush stages.
