Patent number: 11022092Abstract: A method for mounting a rotor to a drive shaft of a wind turbine, the method comprising placing a hub on a surface, attaching a first, a second, and a third rotor blade to the hub to thereby make a rotor in situ. To protect the blades and to avoid fixed lifting lugs on the rotor, the method includes the step of wrapping a sling about each of the blades, attaching each sling to a fitting, lifting each fitting to thereby raise the rotor from the surface, and attaching the rotor to the drive shaft while the position and orientation of the rotor is controlled by the slings.Type: GrantFiled: December 19, 2016Date of Patent: June 1, 2021Assignee: Vestas Wind Systems A/SInventor: Gunnar K.

Patent number: 4697689Abstract: A system for manipulating articles, such as irregular mailpieces in the U.S. Postal Service mail processing system, receives an agglomeration of parcels into a first subsystem where the parcels are separated and are passed to a second subsystem where each parcel is manipulated until its addressee label is directed upward. The first subsystem includes a plurality of individually rotatable cylindrical rollers which form a support surface for the parcels. The rollers produce translation of a parcel by cooperative motion or separation of parts of a pile of parcels by differential motion. The second subsystem includes a high-friction, flexible conveyor belt which in a first mode supports a parcel and in a second mode forms a downward loop in which a parcel can be rotated and inverted. The parcels in both subsystems are manipulated by a five-axis robotic arm which is responsive to a machine vision system measuring the position and physical characteristics of each parcel.Type: GrantFiled: December 26, 1985Date of Patent: October 6, 1987Assignee: RCA CorporationInventor: Ross M.
