Publication number: 20130052446Abstract: A melt-extruded substrate that can be readily thermoformed into a shaped, three-dimensional article is provided. The substrate is formed from a polymer composition that contains a thermotropic liquid crystalline polymer and a unique aromatic amide oligomer. The present inventors have discovered that the oligomer can help increase the “low shear” complex viscosity of the resulting polymer. The ability to achieve enhanced low shear viscosity values can lead to polymer compositions with an increased melt strength, which allows the resulting substrate to better maintain its shape during thermoforming without exhibiting a substantial amount of sag. Due to its relatively high degree of melt strength, the polymer composition is particularly well suited for forming thin extruded substrates for use in thermoforming processes.Type: ApplicationFiled: August 27, 2012Publication date: February 28, 2013Applicant: TICONA LLCInventors: Kamlesh P.

Patent number: 8178032Abstract: The present invention generally relates to a mold assembly (32, 34) and a method of using the mold for the manufacture of composite parts which, more particularly, are generated from a strengthener in a generally solid phase and a matrix in a generally liquid phase. Various types of molds and processes may be used in order to impregnate a strengthener with a matrix such that a composite part may be manufactured, but the efficiency rate and the duration of the manufacturing process significantly varies depending on the chosen type of mold and process. The present invention relates to a mold assembly and to the manufacture of composites by using the mold assembly which includes the injection of the matrix in the mold assembly containing the strengthener and a deformable member (36) which favors the impregnation of the matrix toward the strengthener.Type: GrantFiled: December 2, 2010Date of Patent: May 15, 2012Assignee: Polyvalor, Limited PartnershipInventors: Eduardo Ruiz, Francios Trochu

Patent number: 8176714Abstract: Method for producing a capsule containing beverage ingredients designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, wherein the capsule includes a body with a sealing member attached thereto. The method includes providing the body with a main cavity, injecting at least one sealing material by injection-molding onto at least a portion of the external surface of the body to mold a sealing member sealingly attached to the body, filling the cavity with food ingredients and imperviously closing the cavity with a membrane to provide a closed capsule containing the food ingredients.Type: GrantFiled: April 23, 2007Date of Patent: May 15, 2012Assignee: Nestec S.A.Inventors: Daniel Abegglen, Thomas Kaeser, Alexandre Kollep, Roland Huber

Patent number: 8163209Abstract: A method of controlling the geometry of a composite component (3). The method comprises applying pressure to the component with a pressure transmitter (6), and during said application of pressure: heating the component; measuring the position of the pressure transmitter to produce a feedback signal; and moving the pressure transmitter in response to a change in the feedback signal.Type: GrantFiled: November 12, 2007Date of Patent: April 24, 2012Assignee: Airbus Operations LimitedInventor: Christopher Glazebrook

Patent number: 8158050Abstract: A green tire (G) is formed by stacking a tire component such as a carcass layer (13) on a film (12) which is made of a thermoplastic resin or a thermoplastic elastomer composition and which is disposed on the entire outer circumferential surface of a cylindrical rigid inner die (1) formed of split parts (2). The green tire (G) is placed in a vulcanizing mold together with the rigid inner die (1) and then heated to a given temperature. The film (12) is pressurized from the inner circumferential side and inflated, and the green tire (G) is vulcanized. Thus, unvulcanized rubber of the tire components is pressed toward the inner circumferential surface of the vulcanizing mold and flows in circumferential directions. As a result, volume unevenness of the tire components is corrected. The film (12) which functions as a bladder is tightly bonded to the inner circumferential surface of the tire to become an inner layer of the tire.Type: GrantFiled: October 28, 2008Date of Patent: April 17, 2012Assignee: The Yokohama Rubber Co., Ltd.Inventors: Takuzou Sano, Noboru Takada

Patent number: 8158051Abstract: An intermediate sealing element and method for unsealing a vacuum membrane from one tool surface and transferring it to another tool surface without damaging the vacuum membrane. The intermediate sealing element forms a continuous path around the periphery of a vacuum membrane and is sealed directly to one or more vacuum membranes and a tool surface using any means known in the art to create an airtight seal between two surfaces. The intermediate sealing element is able to withstand high temperatures and high pressure without altering its structural characteristics. Because of its durability, the intermediate sealing element can be removed from the tool surface without tearing or elongating, subsequently allowing the vacuum membranes to be detached from the tool surface without tearing or elongating.Type: GrantFiled: May 7, 2008Date of Patent: April 17, 2012Assignee: Spirit AeroSystems, Inc.Inventors: Steven F. Hanson, Jeffrey W. Priest, Carl R. Fiegenbaum, Kelvin D. Nguyen
