Patent number: 11884550Abstract: Shaped gel articles that are formed within a mold cavity and that retain the size and shape of the mold cavity upon removal from the mold cavity, sintered articles prepared from the shaped gel articles, and methods of making the sintered articles are provided. The shaped gel articles are formed from a casting sol that contains colloidal silica particles that are treated with a surface modification composition that includes a silane surface modification agent having a radically polymerizable group. The sintered article has a shape identical to the mold cavity (except in regions where the mold cavity was overfilled) and to the shaped gel article but reduced in size proportional to the amount of isotropic shrinkage.Type: GrantFiled: August 16, 2017Date of Patent: January 30, 2024Assignee: 3M Innovative Properties CompanyInventors: Kathleen M. Humpal, Melissa A. Lackey, Brant U. Kolb, Paul D. Pennington, Mark J. Hendrickson

Patent number: 10436984Abstract: An optical network comprises a fiber distribution cable and a terminal assembly. The terminal assembly receives a plurality of optical fibers from the fiber distribution cable and distributes one or more individual fibers to one or more single fiber bare-fiber holders that hold and protect each single fiber prepared and configured for splicing via an individual splicing element. The splicing element includes an alignment mechanism having a base plate and a clamp plate. At least one of the base plate and clamp plate is formed from a silica material and at least one of the base plate and clamp plate includes an alignment groove or channel configured to receive the first and second optical fibers in an end-to-end manner. The splice element also comprises an optical adhesive disposed in at least a portion of the alignment groove, wherein the optical adhesive is curable via actinic radiation.Type: GrantFiled: September 5, 2017Date of Patent: October 8, 2019Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: William J.
