Abstract: An illuminated flying disk includes a plurality of light emitters mounted in a flying disk toy as well as a control circuit mounted in a centrally disposed circuit housing on the underside of the disk. A cap for the control circuit housing is rotatable to provide a simple yet rugged switch for selectively supplying power to the light emitters.

Abstract: A saucer-shaped aerial toy has an on-board signaling device actuated only during flight by the closing of a pair of centrifugally-actuated electrical switches. The on-board signalling device may generate sound and/or light which not only have recreational value, but also serve as early warning indicators that the aerial toy is in the vicinity.

Abstract: A flying disk toy comprising a substantially planar disk configured to rotate about a central axis in sustained flight and a centrifugally activated sound generator associated with the disk is disclosed. The disk includes a cylindrical wall perpendicularly projecting from the plane of the disk and which is centrally disposed on the disk relative to its central axis. The centrifugally activated sound generator comprises two diametrically opposed centrifugal switches in series connection, each comprising a radially extending, axially inclined ramp, a pair of electrical contacts symmetrically disposed on opposite sides of the ramp in spaced apart relationship and an electrically conductive weight movably supported on the ramp.

Abstract: A boomerang includes an apparatus to continuously generate audible sound. The generator is located centrally so that flight characteristics of the boomerang are not adversely affected. A resilient member holds a battery in place during use so that the sound does not cease until desired by the user. The resilient member allows the battery to be retainedin a rest position in its holder when no sound is desired.

Abstract: A new saucer-shaped aerodynamic throwing toy is disclosed. The flight body is provided with a shaft on which a propeller is mounted, resulting in an unusual "hopping" effect during use without decreasing the overall flight time. The shaft is removable, thereby allowing the toy to be converted into an implement with more conventional characteristics. The pitch of the propeller blades is adjustable, and the body may be provided with small battery powered lights to enable the toy to be used at night.

Abstract: A flying saucer toy having a pair of LED's mounted diametrically opposed to each other on the rim of its disc-shaped body. The LED's are electrically connected to a printed circuit board and batteries which allow the LED's to strobe imperceptably fast at approximately 100 Hz. A touch-sensitive switch has three terminal posts that extend through the top surface of the disc-shaped body and the bottom ends of the terminal posts are soldered to the circuit board to form a mounting structure for the circuit board. When the flying saucer toy is thrown at night the strobing effect will produce the effect of more than twenty lighted points around the disc perimeter depending upon the rotational speed of the disc.

Abstract: A flying dish having a convex center portion surrounded by a concave ring portion. The convex center portion has the form of the pistils of a flower. The concave ring portion supports petals of a flower. The concave ring portion contains respective pivot axles for the flower petals. Each pivot axle is provided with a coiled spring extending between the inner wall of the concave ring portion and a slot on the back of a flower petal. Each flower petal is provided with a small whistle. When the rotational speed of the flying dish reaches a predetermined level, the flower petals open under centrifugal force and begin whistling due to the air stream. When the speed of the flying dish slows, the flower petals gradually close and the whistling disappears.

Abstract: An optical effect is produced in cooperation with the normal use of an article of manufacture, e.g., a toy such as a frisbee or a ball, or an article of clothing, such as a shoe, by mounting on the article a piezoelectric element for generating electrical energy in response to movement of the article and an optical effect device, such as a neon bulb, gas plasma, liquid crystal, or electroluminescent device, electrically connected to and energized by the element in response to such movement. In one embodiment, the element and device each comprises a thin, layer-like structure, the element and device structures being laminated or attached together.

Abstract: A circuit for controlling lamp flash interval and duration which comprises an NE555 integrated circuit in combination with resistances and capacitances. In the circuit, a resistor and a capacitive switch in series therewith govern flash interval. The capacitive switch includes a normally closed centrifugal switch which, when closed, presents a given capacitance in series with the resistor and when open presents a reduced capacitance in series with the resistor. The capacitance is provided by two capacitors. In one embodiment, when the switch is closed, one capacitor is in series with the resistor and the other is bypassed and when the switch is open, both capacitors are in series with each other and with the resistor. In the other embodiment, when the switch is closed, the two capacitors are parallel with each other and in series with the resistor and when the switch is open, one of said parallel capacitors is bypassed.

Abstract: A dome light and stabilizer fin accessory kit is provided for use with toy flying discs. A socket is attached to the top center portion of the flying disc and a plug is inserted therein. The plug contains either the dome light with battery or a stabilizer fin assembly. The stabilizer fin rotates about a pin connected through an aperture in the plug. The leading edge of the fin includes a counter-balance such as a weight or battery-powered lamp. The trailing end may include an adjustable rudder.
