Abstract: A retaining device for preventing withdrawal of an electric plug from an extension cord socket responsive to forces exerted on a cord connected to the plug. The devices of the first and second embodiments are used with extension cord sockets. In the device of the first embodiment, a resilient C-shaped clamp abuts the opposite end walls of the plug and socket. The ends of the clamp are releasably connected to each other by a flexible chain which positively maintains the plug electrically connected to the socket. In the device of the second embodiment, a pair of retaining straps are secured to one of the connectors, and a pair of ears are secured to the other connector. The ears, engaged by the retaining straps, prevent withdrawal of the plug from the socket. An adaptor shell is provided to allow use of the device of the second embodiment with plugs substantially smaller in width than the socket.

Abstract: A retaining device for preventing withdrawal of an electric plug from a wall or extension cord socket responsive to forces exerted on a cord connected to the plug. The devices of the first and second embodiments are fastened to a wall adjacent a conventional wall outlet. The devices frictionally engage the cord so that forces exerted on the cord are not transmitted to the plug.

Abstract: A wind power converter comprising: a pair of rotatable turbines with elongated curved blades disposed within a rotatable housing on axially parallel shafts, the curvature of the blades of one turbine being opposite to the curvature of the blades of the second turbine so that wind passing between said turbines will rotate the turbines in opposite directions; the housing comprising shaft-supporting sections at the ends of the turbines, lateral sections connecting the end sections, a pair of wind deflectors disposed between the end sections and extending from adjacent edges of the lateral sections toward the midpoint between the turbines and terminating approximately the same distance from each other as the distance between the turbine shafts, and a pivotally mounted vertically disposed vane extending from a portion of the housing opposite to the wind deflectors; said rotatable housing being supported on a vertically disposed central shaft and on a plurality of beams radiating therefrom with the free end of each
