Abstract: A launchable or throwable flying device that comprises a tapering tube or hollow truncated cone shape with a front aperture that is larger in diameter than the rear aperture. Various aerodynamic and design features are designed to optimize the device's performance in flight, such as (but not limited to) a tail section that induces the device to tack into the wind when thrown.

Abstract: A toy throwing disk is configured for spinning about a rotational axis during flight and for producing bubbles during the spinning flight. The disk includes a bubble solution reservoir with outlets, aperture arrays receive bubble solution from the reservoir through conduits and cooperating with passing air during the spinning flight to convert the bubble solution into bubbles. The conduits include an adaptation of hydrostatic valving to control the delivery of the bubble solution and prevent leaking.

Abstract: A launchable device capable of autorotating flight. The device comprises a wing with two airfoils that induce this autorotating flight after launch and ascent.

Abstract: A system for containing bubble solution and converting the solution into bubbles through a particular motion is disclosed. The system includes a sealed reservoir for containing the bubble solution and having an outlet, an aperture array adapted for cooperation with the particular motion to cause the bubble solution to convert to bubbles; and a delivery network adapted for allowing flow of the bubble solution from the outlet to the aperture array only during the particular motion. Several exemplary devices employing the system are also disclosed.

Abstract: Described is a quiet hand-held hair dryer with configuration and component combinations for making the hair dryer exceptionally quiet and efficient. The hair dryer includes a housing having a lower handle portion and an upper body portion separated by an air-directing wall. A large impeller moves air downward from a large top air inlet and passes it outward through a side air outlet in a hair drying stream. An electric motor is mounted in the handle housing adjacent its bottom and is connected in driving relation with the impeller by a long vertical shaft. The motor is mounted in a rubber casing permitting cooling air flow and minimizing vibration to the housing; and the upper end of the shaft is stabilized by a bearing mounted in a rubber housing for the same purpose. The configuration of the described hair dryer permits high air flow with relatively low motor speeds.
