Patent number: 7887742Abstract: The process and the apparatus serve for the blow moulding of containers (2). A parison (1) composed of a thermoplastic material is first subjected to heat conditioning along a transport path in the region of a heating section (30). The parison is then subjected to a forming process within a blow mould with exposure to blowing pressure to give heat container. The heat conditioning of the parisons is carried out by a plurality of mutually superposed radiant heaters (41). The blow moulding of the container is followed by wall-thickness measurement at at least one level within the height of the container. The heating power of a radiant heater associated with this height level is controlled. The control system receives a prescribed wall-thickness value as required value and the measured wall thickness as actual value.Type: GrantFiled: February 22, 2007Date of Patent: February 15, 2011Assignee: KHS Corpoplast GmbH & Co.

Patent number: 7850897Abstract: 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.Type: GrantFiled: March 14, 2007Date of Patent: December 14, 2010Assignee: Spectrum Aeronautical, LLCInventors: Larry J.
