| 20080224360 | METHOD AND DEVICE FOR MANUFACTURING A UNITARY CAUL SHEET - A method and device are provided for manufacturing a unitary caul sheet to be used in creating a composite material fuselage for an airplane. Specifically, a generally tubular shaped tool having a hollow interior cavity defining a fuselage IML surface is provided. In the method, a caul sheet material such as polyurea is applied to the IML surface before an armature is inserted into the interior cavity of the tool. Then, a filler material is introduced between the armature and the caul sheet material. Further, steam is injected to form the filler material into an infrastructure. Then, the caul sheet material is cured before the tool is removed from the caul sheet material to expose the caul sheet to receive composite material. | 09-18-2008 |

| 20090065980 | Method and Device for Blow-Molding Containers - The invention relates to a method and a device for blow-moulding containers from preforms which have been previously heated in a heating section and consist of a thermoplastic material. After being heated, said preforms are transferred to a blowing device in which they are deformed in order to form containers under the action of a blowing pressure inside blow moulds. The blow moulds respectively consist of at least two blow-moulding segments. The preforms are transported together with the blow moulds at least along part of a path of a rotating blow wheel. The blow-moulding segments are braced in relation to each other during at least part of the blow-moulding process. At least one of the blow-moulding segments is pivoted about a rotational axis in order to perform opening and closing movements. Once a blowing station holding the blow-moulding segments is closed, at least one of the blow-moulding segments is then supported, at a distance from the rotational axis and independently from the other blow-moulding segment, in relation to a counter-bearing connected to the blow wheel. The supported blow-moulding segment is at least partially braced in relation to both the counter-bearing and the other blow-moulding segment. | 03-12-2009 |
| 20100164147 | REINFORCED INTERNAL COMPOSITE STRUCTURES - A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers.
