Abstract: The linear roller bearing device provides full support and smooth sliding arrangement between the bearing body and the support rail. Four continuous channels are formed in the bearing body to house a plurality of rollers having identical configuration and dimensions. The rollers have a smooth cylindrical body and conical ends. At least two removable side covers are provided in the bearing body to facilitate access to the rollers for maintenance and replacement purposes. The rollers can be inserted into the continuous channels which are covered with removable end covers.

Abstract: A wind-powered machine is provided in which a vane is driven through a vertical or horizontal arc with a back and forth motion, the motion of the vane serves to actuate a power generating mechanism, in the case where the vane moves in a vertical arc the actuation of the power generating mechanism can be achieved without any translation of the direction of the power transmission system; a governing mechanism serves to vary the response of the vane relative to the wind velocity.
