Publication number: 20140354029Abstract: A seat cushion body and method of producing the same are provided. In a method of producing a seat cushion body, fiber material is inserted into a mold. Heat is supplied to the fibers to cause thermal activation of binding fibers, so as to effect thermal cross-linking. The resulting seat cushion body includes a resilient portion formed from the fibers and having a fiber orientation along a main load direction of the seat cushion body. The seat cushion body may include at least one further portion formed from the fibers, which has a fiber orientation and/or a density different from the fiber orientation and/or different from a density of the resilient portion. The resilient portion and the at least one further portion may be integrally formed from the cross-linked fiber material as a unitary body.Type: ApplicationFiled: August 14, 2014Publication date: December 4, 2014Inventors: Jan Petzel, Alenka Fäller

Patent number: 8895135Abstract: A main body member, a first member, and a second member are joined together to form a laminate. A first edge of a first peripheral portion of the first member and a second edge of a second peripheral portion of second member are welded to each other along a parting line. A height position of the parting line in a thickness direction of the laminate is different between first and second portions defined in a peripheral direction of the laminate. Each of a first curvature radius of a curved shape of the first peripheral portion and a second curvature radius of a curved shape of the second peripheral portion is different between the first and second portions.Type: GrantFiled: November 25, 2013Date of Patent: November 25, 2014Assignee: Meiwa Industry Co., Ltd.Inventor: Kenichi Nonaka

Publication number: 20140339729Abstract: A sealing unit for sealing a gap between a pair of surfaces, the apparatus comprising a nozzle for injecting sealant into the gap; two or more rollers; an endless track which passes round the rollers; and a curing device for directing energy into the gap to initiate cure of the sealant. The sealing unit is moved along the length of the gap. A sealant is injected into the gap from the nozzle and the track is rotated around the rollers as they are moved along the length of the gap. The track is pressed onto the first and second surfaces so the sealant in the gap is constrained by the track to lie substantially flush with the first and second surfaces. Energy is directed into the sealant with the curing device, the curing energy initiating cure of the sealant. The sealing unit is moved along the length of the gap at a rate such that the sealant becomes sufficiently cured when it is in contact with the track so that the track can be peeled away from the sealant as the track rotates round the second roller.Type: ApplicationFiled: July 30, 2014Publication date: November 20, 2014Inventor: Jeremy BRADLEY

Patent number: 8808599Abstract: Provided is a method of manufacturing a damper assembly. In the method, a case constituting an appearance of the damper assembly and having an open surface is molded, the case is inserted in a jig, the case is filled with a thermal insulating material to blow and mold the thermal insulating material, and a closing plate is coupled to the case to cover the open surface of the case. The closing plate contacts the discharge duct when the damper assembly closes the discharge duct. Accordingly, dimension stability, a defect rate, and sealing and insulating performances of the damper assembly are improved.Type: GrantFiled: July 25, 2011Date of Patent: August 19, 2014Assignee: LG Electronics Inc.Inventors: Jaeyoul Lee, Ilyoong Park, Changbong Choi, Miryoung Kang, Manho Park

Publication number: 20140135714Abstract: A novel design and method of attachment of a retention device to a monolithic thin walled deep drawn core provides an efficient system to produce a complete conjunct nozzle assembly. The design of the molded retention device contains the provision for joining the parts together without the use of adhesives or ancillary parts. Additional polymer in the correct amount is molded into the retention device in close proximity to the location where a mechanical lock must be formed to join the two components together. An inventive tool enables the technique for shut off of the monolithic core from the heated thermoplastic polymer allowing formation of a ledge that overhangs the flange of the core. Execution of the process is rapid, low cost and it eliminates damage to the thin wall of the core that would occur if the retention device were molded around the core.Type: ApplicationFiled: November 15, 2012Publication date: May 15, 2014Inventor: Brian Leonard Verrilli

Patent number: 8721959Abstract: A system for self-repairing matrices such as concrete or cementitous matrices, polymeric matrices, and/or fibrous matrices, including laminates thereof The system includes repair agents retained in and/or on vessels, such as hollow fibers, within the matrix. Upon impact, the vessel rupture, releasing the chemicals. For multi-layer laminates, the systems provides a total dynamic energetic circulation system that functions as an in situ fluidic system in at least one layer or area. The energy from the impact ruptures the vessels to release the chemical(s), and mixes the chemical(s) and pushes the chemical(s) and/or resulting compound through the matrix. The repair agents can withstand high temperatures, such as the heat of processing of many laminates, e.g., 250-350° F.Type: GrantFiled: September 9, 2011Date of Patent: May 13, 2014Inventor: Carolyn Dry
