An improved wind-propelled ski apparatus which comprises a ski, risers and deck. The risers comprise upper and lower platforms and connecting positioned members between the platforms. The risers are attached to the ski and provide an elevated surface for the installation of a deck, where the rider's feet are positioned. The elevation of the rider's feet provides greater control of the ski and protection for the rider's feet. The ski is an elongated, planar member having a series of openings alon...

A wind baffle for convertible automobiles including a baffle sheet, first means for affixing the baffle sheet to a pair of opposed regions in the interior of the automobile such that the baffle sheet can be held in place behind the front seat compartment of the convertible automobile to prevent wind currents from passing from the rear of the convertible automobile to the front seat compartment, the opposed regions situated on an axis, and second means for adjustably affixing the baffle sheet to ...

A wind scoop for hatches and designed to direct and restrict the amount of wind through a hatch opening and if necessary, cut the wind completely. The scoop is collapsible for easy storage and transportation. A rigid sheet is scored to define foldable walls that form an intake opening and direct the wind therethrough. A wall is pivotally housed within the walls and movable between two extreme positions for allowing maximum air through or blocking it. A removable notched bar bites on the distal s...

A wind shelter particularly useful for sunbathing on a beach has a floor and wedge-shaped wall that extends along two sides and across the back. The wall is supported by a frame extending around the top edge of the wall and upright support rods holding the frame away from the floor to stretch the side wall to a vertical orientation.

A wind turbine for generating power comprising one or more blades mounted to a shaft for rotational movement in response to an airflow, a housing having a generally central longitudinal axis, the housing surrounding the one or more blades and the shaft, wherein the housing includes an inlet opening and an outlet opening, and an adjustable scoop operably associated with the housing to alter the airflow entering the inlet opening.

A wind instrument having an embouchure and a resonance passage in which between the embouchure and the resonance passage an antechamber is disposed which is bounded at one end by a plate (tone ring), attached to the wall of the resonance passage transversely of the instrument axis and formed with an aperture, and at the other end by a tongue in the form of one or more raised portions extending from the wall downstream of the embouchure.

An instrument for determining the direction and speed of the wind commonly referred to as a "wind sock" which is mounted to rotate through a horizontal plane to indicate the wind direction and is characterized by having provision for also rotating on its own axis to indicate the force or speed of the wind. The wind sock can also be mounted to pivot in a vertical plane in response to the force of the wind.

A wind turbine including a reaction type turbine wheel instead of an impulse type turbine which is normally used for receiving the wind and more efficiently deriving power therefrom and an augmenter means for producing a vortex downstream of the turbine at the exit of the turbine to increase the pressure differential across the turbine thereby increasing the power that may be extracted from the wind.

Wind motors which are propelled by the impact of the wind against the vanes of an impeller wheel, that have wind channeling devices that gather the wind from a large area and funnel it at increased density and pressure to apply multiplied impact against the impeller vanes.

A wind instrument having a relative pure tone is disclosed. The wind instrument includes a tubular body, a secondary treble key, and a control shaft adapted to be rotated by the secondary treble key. The control shaft is pivotally connected to the tubular body and is securely formed with two spaced transverse pieces having respective apertures defined in alignment. A bar has a pair of opposed, egg-shaped ends, and each of the egg-shaped ends defines a threaded hole therein and a plurality of spl...
