Patent number: 9353729Abstract: An aerodynamic hub assembly for a wind turbine is disclosed. The hub assembly may include a hub extension, a rotor blade having a blade root and a blade tip, and a hub airfoil section mounted at least partially over the hub extension. The hub airfoil section may be fixed relative to the rotor blade or may be configured to rotate about a common pitch axis with the rotor blade. The hub extension may be connected to and extend radially from a center of the hub assembly. Further, the hub assembly may include a pitch bearing having an inner race and an outer race, wherein the pitch bearing may be coupled between the hub extension and the blade root. Additionally, the hub assembly may also include an aerodynamically-shaped spinner, wherein the spinner may house at least a portion of a root structure extending radially from the center of the hub assembly.Type: GrantFiled: July 2, 2013Date of Patent: May 31, 2016Assignee: General Electric CompanyInventors: Ian David Wilson, Kevin Wayne Kinzie, James Henry Madge, Daniel Jason Erno, Michael Colan Moscinski, Zaeem Ashraf Khan, Dmytro Floriyovych Opaits

Patent number: 9347033Abstract: A method of processing an adipose tissue to collect adipose derived regenerative cells is provided, wherein the method comprises providing a vessel comprising a fluid jet mixer, introducing the adipose tissue into the vessel, introducing a buffer solution into the vessel; washing the adipose tissue using the fluid jet mixer; introducing an enzyme solution into the vessel; initiating jet mixing into the vessel comprising the adipose tissue, the enzyme solution, and the buffer solution using the fluid jet mixer to digest the adipose tissue to form a digestion product; phase-separating the digestion product into a digested buoyant fat layer and a non-buoyant aqueous layer; and collecting the non-buoyant aqueous layer comprising the adipose derived regenerative cells. A system of processing an adipose tissue to collect adipose derived regenerative cells is also provided.Type: GrantFiled: July 30, 2015Date of Patent: May 24, 2016Assignee: General Electric CompanyInventors: Zaeem Ashraf Khan, Aaron Joseph Dulgar-Tulloch, Stefan Rakuff, Philip Alexander Shoemaker, Erik Leeming Kvam, Xiaohui Chen, Jaydeep Roy
