Abstract: A noise making valve for a toy balloon includes a casing enclosing a moveable valve body and a resonant reed disposed upstream of the valve body. A perforated membrane substantially closing the end of the casing opposite the balloon is depressable to lift the valve body from its seat, causing emission of a tone. The valve body is positively enclosed in the casing, and the reed is protected by folded-over tabs, such that no part of the valve is removable by the user. Safety features also include an enlarged trumpet shape and a restriction preventing a complete sudden ejection of the valve from the balloon.

Abstract: A musical instrument that produces whistle-type tones responsive to the impingement of sunlight or other source of electromagnetic radiation upon one or more radiation-absorbent porous-to-air, generally disc-shaped generator member or members disposed interiorly and in the lower half of a vertically oriented transparent or partially transparent tube with angled open ends. The generator member or members may be in the form of a wire mesh or gauze. In a preferred embodiment, Fresnel lenses are employed to focus sunlight on the generators contained within a plurality of tubes of differing lengths that are grouped together to form a musical instrument suitable for display in public places for the entertainment and scientific edification of the public.

Abstract: A method and apparatus for calling wild turkeys using a strip of flexible cloth which is longer than wide and having a first end and a second end, a reinforcement structure at each end of the cloth for holding the ends straight, and a flap attached to each of the side edges of the cloth. The method includes the steps of grasping one end of the cloth with one hand, grasping the other end of the cloth with the other hand, moving the hands towards each other while holding the ends whereby the cloth is allowed to become loose, and rapidly jerking the hands apart while still holding the cloth to stretch the cloth tight, thereby simulating the sound of a wild turkey flapping its wings.
