Patent number: 9878492Abstract: The problem to be solved is, when printing a 3D object by using a 3D printer of fused-deposition-modeling type or another type, to enable printing it even when the filament is not supported from underneath by avoiding filament drop by generating force to push the extruded filament to the neighbor filament, and to enable arraying the filaments to a horizontal direction. To avoid filament drop, force that pushes the newly extruded filament to the neighboring filament is generated, and filament drop is avoided. To do so, compression or extension power is generated by controlling the filament cross section by controlling the filament cross-section (i.e., the extrusion amount) and stiffness of the filament is controlled by controlling the temperature or light.Type: GrantFiled: June 1, 2015Date of Patent: January 30, 2018Inventor: Yasusi Kanada

Patent number: 9878502Abstract: In a method for processing a fiber compound structure, an unhardened fiber layer is arranged on a surface section of the fiber compound structure. A pressure cushion is arranged above the surface section. The pressure cushion has a pressure cap and a pressure-tight cap mat pressure-tightly connected to a circumferential border of the pressure cap such that the cap mat limits a pressure area together with the pressure cap. An overpressure in the pressure area is generated. The pressure cushion is pressed onto the fiber compound structure such that the overpressure presses the cap mat against the fiber layer while supporting the fiber compound structure on a side of the fiber compound structure that is opposed to the surface section.Type: GrantFiled: September 6, 2016Date of Patent: January 30, 2018Assignee: AIRBUS OPERATIONS GMBHInventors: Felix Caspar Helfrich, Hans Marquardt

Patent number: 9878503Abstract: Methods, a consumable assembly, and a tool for preparing a composite structure from a laminate disposed on a surface of a mold. The method involves preparing consumable materials, such as a breather sheet and a vacuum bag, and preparing an inflatable tool, outside of the mold. These prepared consumable materials and the inflatable tool are then inserted into the mold, and the inflatable tool is inserted into a folded assembly of the breather and vacuum bag. Once inserted into the mold, the inflatable tool is inflated, which deploys the consumable materials against the laminate. A vacuum can be generated, which maintains the deployed consumable materials against the laminate. This can be done for many hours. Finally, the laminate is cured inside the mold so as to form the composite structure.Type: GrantFiled: August 23, 2012Date of Patent: January 30, 2018Assignee: BOMBARDIER INC.Inventors: Alain Charbonneau, Jérôme Ferland, Jacques André, Jose Alberto Urbiola

Patent number: 9878505Abstract: A tool for forming a C-section beam made of carbon fiber includes a straight elongated mandrel with a rectangular or trapezoidal cross-section. The mandrel has three consecutive outer faces, with a planar face configured to form a surface of the web of the C-section beam, and two opposing lateral faces, configured to form two respective surfaces of the flanges of the C-section beam. The mandrel has a distributed perforation on at least one of the three outer faces and an inlet/outlet connection to connect the mandrel to an external source of vacuum and/or compressed air. Passages are formed inside the mandrel to establish a fluid communication between the distributed perforation and the inlet/outlet connection. Through the distributed perforation, a vacuum is applied to the interface between the mandrel and the C-section beam to retain the C-section beam on the mandrel while lifted and turned by 180° for coupling to a similar C-section beam to assemble an H-beam.Type: GrantFiled: December 11, 2014Date of Patent: January 30, 2018Assignee: ALENIA AERMACCHI S.p.A.Inventors: Daniela Carretti, Gianni Iagulli, Gianpiero Lembo, Alberto Russolillo, Carmine Suriano

Patent number: 9878506Abstract: Method for making a tough and compliant hydrogel. A precursor hydrogel is made of a first polymer selected to maintain high elasticity and a second polymer selected to dissipate mechanical energy. The precursor hydrogel is stretched to a multiple of its original length to form a pre-stretched hydrogel. The pre-stretched hydrogel is allowed to relax and is soaked in a biocompatible solvent to reach equilibrium swelling of the pre-stretched hydrogel whereby shear modulus of the hydrogel is reduced.Type: GrantFiled: December 16, 2015Date of Patent: January 30, 2018Assignee: Massachusetts Institute of TechnologyInventors: Xuanhe Zhao, Shaoting Lin, Hyunwoo Yuk

Patent number: 9878507Abstract: The present application relates generally to retroreflective sheeting and the tools and methods used to make retroreflective sheeting. Microreplication tools and sheeting include controlled surface structure or haze. The surface structure or haze can be introduced, for example, by chemical etching of the tool surface and/or electroplating.Type: GrantFiled: June 6, 2014Date of Patent: January 30, 2018Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Kenneth L. Smith, James R. Imbertson, John C. Kelliher, John A. Worrell, Sidney A. Ellingstad

Patent number: 9878508Abstract: A tire tread may be formed by simultaneously extruding a tread cap formed of a first material and a tread base formed of a second material having a substantially different stiffness property than the first material. One tread element may have a strip of the second material extending from the tread base into the tread cap and, a second tread element may also have a strip of the second material extending from the tread base into the tread cap.Type: GrantFiled: November 30, 2010Date of Patent: January 30, 2018Assignee: The Goodyear Tire & Rubber CompanyInventor: Paul Harry Sandstrom

Patent number: 9878509Abstract: A shoe mold structure contains: a base, a lower part, an upper part, a mold core, and two connecting rod assemblies. The base includes a movable space, and the lower part includes a lower cavity, a through orifice, and two guiding slots. The upper part includes an upper cavity and at least one feeding orifice, and a connecting face of the upper part and the lower part flushes with a connection section of a body and a sole of a shoe. The mold core includes a molding portion, an extension, a holding plate, and two guide plates, wherein the extension extends to the movable space from the molding portion via the through orifice. Each connecting rod assembly couples with each of the two side surfaces of the upper part and said each guide plate.Type: GrantFiled: January 19, 2016Date of Patent: January 30, 2018Inventor: Chia-Hung Wu

Patent number: 9878510Abstract: A pressing apparatus includes a driving device, a platform configured to support a workpiece, a movable support mounted to the driving device, a pressing member rotatably mounted to the movable support, and a limiting block mounted on the platform. The movable support is movable in a direction substantially perpendicular to the platform. The limiting block rotates the pressing member down pressing the workpiece between the platform and the pressing member when the movable support moves.Type: GrantFiled: January 6, 2015Date of Patent: January 30, 2018Assignee: ScienBiziP Consulting(Shenzhen)Co., Ltd.Inventors: Wei Wu, Chieh-Yu Lee

Patent number: 9878511Abstract: Improved bales may be formed using methods that include baling equipment with multi-component bolster assemblies that may ease installation and removal, reduce wear and tear and maintenance, and/or improve efficiency by reducing material waste, imperfections, and/or contamination. The bolster assemblies may include a plurality of coupling portions that engage a hydraulic rod and may enable the bolster assembly to self-center within a press chamber during normal baling operations. The bolster assemblies also may include an island portion that may be attached to the coupling portions and to a bolster cap, and the latter may be attached using retainer bolts having substantially flat, non-circular heads. The bolts may reduce irregularities in the bale and/or prevent material seepage into the bolster assemblies. During maintenance, an operator may remove only the bolster cap island assembly for cleaning, substantially reducing the time and strength needed to clean and/or repair the baler and reduce downtime.Type: GrantFiled: January 5, 2016Date of Patent: January 30, 2018Assignee: Karltex Machine, Inc.Inventors: Sig Fragstein, Donnie L.
