| 20080217821 | Welding Method by Means of Electromagnetic Radiation - Two shaped articles A and B which are not directly weldable to one another can be welded to one another with the aid of a film C if the material of the first surface of this film is compatible with the material of the shaped article A and the material of the second surface of this film is compatible with the material of the shaped article B and if either the film C or a surface region in contact therewith absorbs electromagnetic radiation. The welding is carried out by brining the first surface of the film C into contact with the shaped article A and the second surface of the film C into contact with the shaped article B and inputting electromagnetic radiation. | 09-11-2008 |
| 20080272521 | INFRARED PLASTIC WELDING WITH RECIRCUALTION OF UNABSORBED INFRARED LASER LIGHT TO INCREASE ABSORPTION OF INFRARED LASER LIGHT - Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated back to the low absorption weld interface for reabsorption in the process. A beam of infrared laser light is directed at the plastic parts to be welded, a transmissive first part and an absorptive (or partially absorptive) second part. The infrared laser light impinges the transmissive part and first transits through the transmissive part to be welded to a weld interface at the junction of the two parts. At the weld interface, either the infrared laser light is partially absorbed by an additive infrared absorber, the infrared laser light is partially absorbed by the absorptive part, or both. The portion of the infrared laser light that is not absorbed continues through the absorptive part and exits the far side. This infrared laser light is then redirected back to the weld interface. On the second pass (and any subsequent passes thereafter), more infrared laser light is absorbed in the partially absorbing medium (the additive infrared absorber, the absorptive part, or both). In an aspect, the parts are tubular parts with the transmissive part coaxially surrounding the absorptive part. The infrared laser light is redirected with a cylindrical mirror that coaxially surrounds the tubular parts. In an aspect, the parts include a tubular part and a fitting and the infrared laser is redirected with a spherical mirror that surrounds the parts. | 11-06-2008 |
| 20090008833 | Method for Forming Nano-Dimensional Clusters and Setting Ordered Structures Therefrom - The inventive method for forming nano-dimensional clusters consists in introducing a solution containing a cluster-forming material into nano-pores of natural or artificial origin contained in a substrate material and in subsequently exposing said solution to a laser radiation pulse in such a way that a low-temperature plasma producing a gaseous medium in the domain of the existence thereof, wherein a cluster material is returned to a pure material by the crystallization thereof on a liquid substrate while the plasma is cooling, occurs, thereby forming mono-crystal quantum dots spliced with the substrate material. Said method makes it possible to form two- or three-dimensional cluster lattices and clusters spliced with each other from different materials. The invention also makes it possible to produce wires from different materials in the substrate nano-cavities and the quantum dots from the solution micro-drops distributed through an organic material applied to a glass. | 01-08-2009 |

| 20110148007 | PROCESS FOR PRODUCING FIBRE PREFORMS - A process for producing fibre preforms for composite material components makes it possible to directly produce complex geometries in a flexible and low-cost manner by applying a plurality of dry fibre rovings independently of one another even in spatially uneven contours. It is no longer necessary to use cut fabric strips since fibre preforms are produced straight from the dry fibre rovings. This obviates the need to carry out production, transport and order picking processes. It is not necessary to cut fibre strips to size, and therefore a saving may be made on material. In addition, it is possible to increase the mechanical characteristic values in the composite material because it is not necessary to sew fibre webs. The described process can also readily be scaled since the number of dry fibre rovings arranged next to one another make it possible to vary the area which can be covered. | 06-23-2011 |
