Abstract: A wind turbine housing is provided for mounting to the roof of a building. The housing defines a Venturi pathway for collecting and accelerating wind to one or more rotors, which are coupled to one or more generators. The rotors are housed in the throat of the Venturi such that wind is accelerated to the rotors to maximize energy generation. The generators may be located within an upper chamber of the housing. The Venturi structure may be formed, in part, by the roof line of the building. A series of wind turbine housings may be mounted atop a single building and wired for use within the building, with excess power converted to AC and delivered to the associated power grid.

Abstract: A leg device with means for gripping, or handles, is used to aid in lifting a jumping player, especially for lineouts in Rugby Union. The simple, reusable, easy to use leg device provides a level of effectiveness, comfort, convenience, and safety not provided by conventional methods. In a leg sleeve embodiment, means for gripping include a thickened band or grip attached to a sleeve material. The means for gripping may be formed by attaching a semi-rigid material. The means for gripping may be formed by attaching extra layers in sections, in rolls, in folds. The means for gripping may be shaped to match the hand of a lifter. To use, leg sleeves are applied to the legs of a jumper. Other embodiments of leg devices include leg glove or mitt and various leg straps. An improved leg glove further comprises a non-elastic base strap. An improved leg sleeve comprises a base strap and a cross strap attached to a sleeve of stretch material. When the jumper jumps, one or more lifters grip the leg device.

Abstract: To provide for modular arrangements, a six-sided pay telephone housing is constructed using vertically oriented panels. The panels are connected to each other using fastenerless moldings that allow for rapid construction of the housing and easy replacement of the panels. Provision is also made in the housing for an electronic information display as well as replaceable advertising placards.
