Abstract: A disclosed gas turbine engine includes a first electric motor assembly that provides a first drive input for driving fan blades about an axis. A geared architecture is driven by a turbine section and is coupled to the fan section to provide a second drive input for driving the fan blades. A second electric motor assembly is coupled to rotate the geared architecture relative to a fixed structure for controlling a speed of the fan blades provided by a combination of the first drive input and the second drive input.

Abstract: A wind powered generator comprising first and second current generator means arranged to generate electric current in response to relative rotation between the two generator means; at least one rotary part having vanes, the rotary part being operatively connected to one of the generator means and arranged to rotate in a first direction around an axial shaft when exposed to a flow of air perpendicular to the shaft; and rotary part barrier means arranged in stationary relation to the rotary part, the barrier means configured to provide a barrier sector around a portion of the vane free edge path of the vane configured to inhibit air which follows a vane rotating into the barrier sector from discharging outside of the vane free edge path whilst the vane is rotating through the barrier sector.

Abstract: A putting practice device and method for its use that assists a golfer to properly align his or her body and putter, in relation to the ball and the hole or target. The putting practice aid includes a flat mirrored surface, a hole in the middle to holding a golf ball in place, and two perpendicular lines running through its center printed on one side. The golfer uses the perpendicular lines, according to a method, to properly align his or her body and clubface to the hole or target.
