Patent number: 9453197Abstract: A method of making a carrier for growing cells, including providing a polymer film; embossing a patterned surface one or more sides of the polymer film with an embossing roller; generating a pattern of structured indentations on the polymer film; and discretizing the patterned polymer film into a plurality of portions. The embossing pattern generates relief features on the carrier surface. An alternative method of making a carrier is also provided, including extruding a polymer film; embossing a patterned surface on the polymer film with a roller; generating a pattern of structured indentations on the polymer film; imparting a surface treatment to the film; and discretizing the treated polymer film into a plurality of portions.Type: GrantFiled: November 2, 2011Date of Patent: September 27, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Yosang Yoon, Slawomir Rubinsztajn, Joel Matthew Caraher, Gary Stephen Balch, Prameela Susarla

Patent number: 9249530Abstract: A fiber preform architecture and method of making, including a plurality of fiber bands. Each band of the plurality of fiber bands is placed at a time, at a predetermined position and orientation, to generate an interwoven and interlocking pattern between the fiber bands. Each of the plurality of fiber bands is formed of a plurality of fiber tows, positioned side by side at a predetermined spacing to define one or more gaps between each tow in the fiber band and define a secondary based interleaving within each of the fiber bands. The plurality of fiber bands are interwoven in an in-plane and out-of-plane orientation by interleaving each of the plurality of fiber bands with one or more of the plurality of fiber bands previously laid down and not in a common plane. The plurality of fiber bands include three or more different orientation angles and provide uniformity in coverage.Type: GrantFiled: May 30, 2013Date of Patent: February 2, 2016Assignee: General Electric CompanyInventors: Yosang Yoon, Mark Ernest Vermilyea, Teresa Tiashu Chen-Keat, Ming Xie
