| 20090035412 | HYBRID LAY-UP TOOL - The present invention relates to a hybrid lay-up tool comprising a thin metallic working surface and a composite back structure. The working surface may be an Invar working surface, and the working surface and the back structure may be coupled using a self-locking connection mechanism. The present invention also relates to a method for providing a hybrid lay-up tool. The method may include providing a metallic face sheet, providing a composite back structure, and operably coupling the metallic face sheet with the composite back structure using a self-locking connection mechanism. | 02-05-2009 |
| 20110027405 | Corner-Consolidating Inflatable Method for Manufacturing Composite Structures - An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions. | 02-03-2011 |
| 20120135099 | METHOD AND APPARATUS FOR RAPID MOLDING OF WIND TURBINE BLADES - A compliant cover is placed over a part being molded in a molding process. The compliant cover is formed from a plurality of longitudinal cells positioned next to one another. At least one communication port is coupled to each longitudinal cell, and a source of fluid media at a preselected temperature is coupled to the communication ports whereby the longitudinal cells may be filled with the fluid media at the preselected temperature. The compliant cover may thus be used to selectively heat and cool the part being molded to decrease the time required by the part to rise to the temperature required to cure the resin in the part and to cool the part so that it can be removed from the mold. | 05-31-2012 |
| 20120308681 | Intelligent Slitting - A system for managing elongation and stress dispersal in a bladder used during a deep draw high pressure process. Resilient bladder material is slitted at concentric or peripheral intervals from the bladder edge(s). The slits above are offset from slits below, such that as the bladder is stretched with deformational forces, the slits are widened, and as deformation forces are abated or relieved, the bladder and its slitting reassume their pre-deformation configurations. | 12-06-2012 |
| 20130209601 | PROCESSES AND SYSTEMS FOR MANUFACTURING SPARS AND OTHER HOLLOW STRUCTURES - Processes for manufacturing hollow structures such as spars for helicopter rotor blades, fixed wings for aircraft, and other aerostructures can include the provision of a path for gases to exit the material from which the spar is formed as the material is heated and cured, to help eliminate voids within the material caused by the presence of such gases. | 08-15-2013 |

| 20090041883 | Apparatus for fabricating flat panel display - This invention relates to a flat panel display and a fabricating method thereof that are adaptive for conducting a patterning process without using a photo process to thereby reduce its process time and minimize pattern defects. A fabricating method and device of a flat panel display according to an embodiment of the present invention spreads an etch-resist on a thin film and forms an etch-resist pattern on a thin film by pressing a soft mold of a permeable structure to the etch-resist. | 02-12-2009 |

| 20120009294 | METHOD AND APPARATUS FOR STRETCHING AND CRYSTALLIZING THE NECK FINISH OF A MOLDED PLASTIC ARTICLE - Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish portion, is positioned to enable insertion of a mandrel into an open top aperture of the finish portion to widen the finish. | 01-12-2012 |

| 20090169668 | TRANSVERSE STRETCHING DEVICE - A transverse stretching device comprises two stretching wheels and endless bands arranged against them and revolving around band guide rolls so that a plastic film to be stretched is arranged at its both edges between a stretching wheel and a band. The stretching wheels and the bands are arranged in such a way that in the direction of travel of the plastic film they are further apart from each other at the end than in the beginning, whereby the transverse stretching device stretches the plastic film in the transverse direction. The stretching wheels are rims open in the center and the device includes heating means arranged through the rims at least at some angle between the stretching wheels. | 07-02-2009 |

| 20110020488 | APPARATUS FOR FABRICATING ELECTROLUMINESCENT DISPLAY DEVICE - The apparatus for fabricating an organic electroluminescent device which can distribute stress applied to the mask uniformly to form precise and reliable light emitting layers is disclosed. The apparatus for fabricating an electroluminescent device according to the present invention comprises a plurality of grippers disposed in a zigzag state at a periphery of a mask for clamping the mask, a plurality of jaws formed on each gripper and contacting with the mask, and power supplying units for supplying power to the grippers to stretch the mask. Each of the grippers is divided into a connecting section connected to the power supplying unit and a head section integrated into the connecting section, and a plurality of jaws are formed on the head section of each gripper, and odd (or even)-numbered grippers disposed at each side of the mask are disposed in a more forward position than even (or odd)-numbered grippers. Accordingly, the head section of each even (or odd)-numbered gripper is placed between the connection sections of two adjacent odd (or even)-numbered grippers. The head sections of even-numbered grippers and the head sections of odd-numbered grippers are arranged alternatively in two different imaginary lines. Also, the jaws are arranged in a line on the head section of each gripper or are arranged in a zigzag state on the head section of each gripper. At this time, the jaws are arranged by equal distance from each other. | 01-27-2011 |

| 20130101694 | Method and Forming Tool for Producing a Fiber Composite Preform - A method and forming tool produce a multi-dimensionally profiled preform from a multidirectional fiber composite material. A tensioning frame envelops top and bottom tool components and fixes the fiber composite material so it is allowed to be subsequently fed-in under frictional engagement. In order to compensate for excess material in regions where a shaping gap has a weaker profile, the tool components have forming elements arranged in the edge trimming zone of the preform and defining between them a drawing-through gap for the material. The drawing-through gap becomes increasingly the shape of a bead in synchronism with the tool components closing movement, and/or the tensioning surface of the tensioning frame is vertically adjusted relative to a tool component inlet surface in the forming phase such that a drawing edge for the material is formed in the tensioning surface. | 04-25-2013 |
