| 20080230368 | Process for the purification of lactams - A method and a plant are disclosed for purifying lactams, particularly lactams obtained by cyclizing hydrolysis of aminonitrile. The purification of ε-caprolactam obtained by cyclizing hydrolysis of aminocapronitrile is described which includes eliminating the ammonia from the reaction medium of the hydrolysis, then recovering the lactam from said medium in purified form. The recovery is carried out by performing at least a distillation of the lactam in the presence of a base producing optionally a fronts fraction comprising compounds more volatile than the lactam, a fraction comprising the lactam to be recovered to the degree of desired purity and a distillation tails comprising the lactam and compounds less volatile than the lactam. The distillation tails are treated by various processes such as evaporation in thin layers to recover the major part of the caprolactam and recycling the latter in the purification process. | 09-25-2008 |

| 20080288944 | Consistent Method System and Computer Program for Developing Software Asset Based Solutions - A method, computer program and system for consuming reusable software assets, said assets being described with elements and attributes, said assets containing at least one variable element (VPs) themselves containing at least one variant. The user executes a program on a computer by first choosing the asset to be consumed. A decision tree corresponding to the asset is traversed, each decision point corresponding to a variable element. The decision point is processed by asking the user inputs to modify the variants of the corresponding variable elements. The modified variable elements are stored. The dependency of the decision point is indicated by a dependency attribute in the variable element. | 11-20-2008 |
| 20090083268 | MANAGING VARIANTS OF ARTIFACTS IN A SOFTWARE PROCESS - In some embodiments the management of revisions to segments of code or artifacts is disclosed. Such management can assist a software developer in the development of software. In some embodiments, a developer can retrieve a versioned file from a repository, modify content of the versioned file to create a variant of the versioned file, compare the variant to the versioned file, and determine a difference between the versioned file and the variant. Then, the one or more attribute can be assigned to the differences and the attributes can be indexed such that the variants can be located in response to a search. In some embodiments variants can be indexed based on a variability point to which they can be matched. Other embodiments are also disclosed. | 03-26-2009 |

| 20080206752 | Method For the Photochemical Attachment of Biomolecules to a Substrate - Methods and devices for attaching biomolecules to a solid substrate surface for example to the inner surface of a capillary. In particular, the invention relates to compounds and methods for creating patterned arrays of biomolecules inside fused silica capillaries so that a plurality of bioassays can be conducted simultaneously. | 08-28-2008 |
| 20090075091 | RIGIDIFICATION OF STRUCTURES TO BE DEPLOYED BY INFLATING, PARTICULARLY FOR USE IN SPACE - The invention relates to the stiffening of inflatably deployable structures, in particular for space use. | 03-19-2009 |

| 20080255332 | Method For Enhancing Adherence of Carbon Fibers With Respect to an Organic Matrix - The invention relates to a process for improving the adhesion of carbon fibres with regard to an organic matrix forming a composite material with these fibres, this composite material being obtained by bringing the fibres into contact with a resin which can be cured by chain polymerization and then polymerizing the resin, which process is characterized in that it comprises the grafting, to the surface of the fibres, before they are brought into contact with the resin, of groups capable of acting as chain transfer agents during the polymerization of said resin. | 10-16-2008 |
