Abstract: The present description relates to a tower-mounted wind power system that comprises a supporting structure configured to support and protect a vertical-axis wind turbine arranged inside said structure, wherein the vertical-axis wind turbine comprises a variable number of air-collection levels, each of said air-collection levels made up of a propeller, wherein the vertical-axis wind turbine is made up of the propellers of the air-collection levels and a vertical shaft, each of the propellers of the turbine comprising a first and second plurality of air-collection elements in order to improve the collection of wind power.

Abstract: To provide synchronization between the drawing roller and the warp beam of a loom, direct transmission is provided between the two members by means of an intermediate shaft which is independent of the speed of the loom. Any variation in the density of the fabric is transmitted to the intermediate shaft and an automatic adjustment is afforded in the drawing roller and the warp beam.

Abstract: In a control mechanism for automatically operating a warp beam in a loom, a comparison regulator is associated with a thread guide roller over which the warp passes and the regulator, through a cam arrangement, operates micro-switches for controlling the operation of an electric motor. The electric motor drives the warp beam through the medium of a variator. Further, an automatic zero setting is associated with the warp beam and operates in cooperation with the variator.
