摘要： A controlled motion hinge assembly having a base with a first actuator mount, a pivot arm with a second actuator mount, a hinge pivotally connecting the base to the pivot arm to be movable between an extended position and a retracted position, and an actuator shaft. The shaft has a first end, a second end, and a threaded body extending between the first and second ends. The first end is configured to receive a drive torque about the actuator shaft axis. The second end is rotatably connected to the second actuator mount, but fixed thereto along the actuator shaft axis. The threaded body engages a threaded bore of the first actuator mount such that rotation of the body causes the first actuator mount to move along the actuator shaft axis. Also provided is a pole assembly, and a method for retrofitting a pole, with a controlled motion hinge.

摘要： Antenna tower construction/deconstruction biasing assemblies are provided. The biasing assemblies can be configured to extend between a standard and an antenna tower. The assemblies can include: an adjustable linear extension extending between a first end configured to couple with the standard and a second end configured to couple with the antenna tower; and a biasing mechanism configured to adjust the length of the linear extension and maintain the rigid engagement during transitioning of the tower from a down/erect position to an erect/down position. Methods for constructing/deconstructing an antenna tower are provided. The methods can include providing a biasing assembly.

摘要： Vertical axis wind turbine, indistinctly applicable in land or sea, the main characteristic of which is its low visual impact due to the collapse of its tower and rotor as required by environmental or meteorological conditions.It is constituted by a structure that includes a base (3, 5), a plurality of supporting arms (10, 13), an elevation set (6, 7, 8) and a drive shaft (17) that acts on the generating elements (29) arranged at the base. Said structure supports a rotor (1) and its corresponding blades (2), attached by means of motorized shafts (20) that collapse and expand the blades (2) over the rotor (1).Whenever the electric motor (6) winds the tensioning element (8) attached to two pairs of lower arms (10), they rotate at their base and intermediate point and raise, during their movement, the upper arms (13) and the drive shaft (17). The entirety of this structure is secured with braces (21, 24), which act on the upper and lower part of their corresponding arms (10, 13), achieving a safe collapse and expansion.
