Patent number: 8101109Abstract: Solution casting of polymer film (76, 102) is provided. A dope (22, 115-117) containing a polymer of cellulose triacetate and solvent is cast on a casting support band (34, 121) which moves, to form a cast film (69, 122), and then the cast film is stripped from the casting support band and dried, to produce the polymer film. In the solution casting, the cast film is cooled shortly before stripping the cast film from the casting support band. Preferably, a cooling temperature to which the cast film is cooled is set lower than 6 deg. C. The cast film is cooled within a predetermined cooling region, disposed to start at a stripping point for the cast film, and to extend upstream therefrom with a length equal to or less than 25% of the length of the casting support band. The cast film is blown by cooling gas caused to flow for cooling.Type: GrantFiled: March 2, 2006Date of Patent: January 24, 2012Assignee: Fujifilm CorporationInventor: Ryo Takeda

Patent number: 8097198Abstract: A method for producing an article of composite material. A female molding tool is provided. A form bag is provided. At least one prepreg is placed in the molding tool. A heel shaped hard tool part. A hard tool part is placed at the female tool close to an edge of the laminate being placed in the mold. The form bag is placed in the female tool so that the bag seals towards the heel shaped tool part, in such a way that, at a later air evacuation of the bag, an increased pressure that the bag will apply towards the laminate reaches a radius before the pressure reaches an edge.Type: GrantFiled: October 10, 2006Date of Patent: January 17, 2012Assignee: SAAB ABInventors: Max Krogager, Mathias Larsson, Claes Rudqvist, Jan Vaara

Patent number: 8097195Abstract: The invention relates to a method for energy usage during the cooling of extrusion profiles, preferably pipes, wherein energy is supplied in the form of heat for melting the plastic and heat is withdrawn from the plastic again for shaping at least in the devices of mold, calibration, and cooling bath until the plastic is self-supporting. According to the invention, it is provided that a coolant medium runs through the extrusion line opposite to the extrusion direction for cooling, the medium which is used for cooling being guided from one device to the next and the coolant medium heating further in each device.Type: GrantFiled: October 17, 2008Date of Patent: January 17, 2012Assignee: Battenfeld-Cincinnati Austria GmbHInventor: Erik Sehnal
