Abstract: A wind turbine blade includes an upper shell with a first portion molded to a second portion by a seamless connection extending along at least a majority of the width of the upper shell. The wind turbine blade also includes a lower shell with a third portion molded to a fourth portion by a seamless connection extending along at least a majority of the width of the lower shell. The first, second, third and fourth portions are made of a fiber reinforced resin construction. A first insert is enveloped within the upper shell between the first portion and the second portion, the enveloped first insert defining a first spar portion. A second insert is enveloped within the lower shell between the third portion and the fourth portion, the enveloped second insert defining a second spar portion. The inserts defining a density lower than the density of the fiber reinforced resin material. The upper shell is bonded to the lower shell adjacent the right and left sides thereof.

Abstract: In a weight lifting machine having a manually engageable mechanism which is movable along a predetermined path of movement wherein the manually engageable mechanism is anchorable to a weight mechanism which resists movement of the manually engageable mechanism, an apparatus for positioning the manually engageable mechanism in a selected initial position along the path movement, the apparatus comprising, an elongated rod having a mesh mechanism on a surface of the rod and a sleeve having a mesh mechanism receivably interlockable with the mesh mechanism of the rod, one of the rod and the sleeve being connected to the manually engageable mechanism and movable in unison with movement of the manually engageable mechanism, the other of the rod and the sleeve being anchored to the weight mechanism, the mesh mechanisms of the rod and the sleeve being reversibly interlockable and unlockable such that the rod and the sleeve move in unison with each other when interlocked and such that the manually engageable mechanism

Abstract: Apparatus for performing weight resistance exercise via manual rotation, the apparatus comprising: a rotatable member mounted on an axle, the axle being manually engageable for application of manual force to rotate the rotatable member; a pair of cable stops each connected to an end of a respective cable which is interconnected to a weight, the weight through the cable holding the stops within a respective mounting aperture; the rotatable member having a pair of retaining members, each retaining member receiving and retaining a respective stop member upon rotation of the rotatable member; the cable being interconnected to the weight such that rotation of the rotatable member is resisted by the weight through the cable upon application of manual rotating force to the axle.
