20110027496METHOD FOR PRODUCING A COATING THROUGH COLD GAS SPRAYING - The embodiments include a method for producing a coating through cold gas spraying. In the process, particles according to the embodiments are used which contain a photocatalytic material. In order to improve the effect of this photocatalytic material (such as titanium dioxide), a reactive gas can be added to the cold gas stream, the reactive gas being activated by a radiation source not shown, for example by UV light, on the surface of the coating that forms. This makes it possible to, for example, dose titanium dioxide with nitrogen. This allows the production of in situ layers having advantageously high catalytic effectiveness. The use of cold gas spraying has the additional advantage in that the coating can be designed to contain pores that enlarge the surface available for catalysis.02-03-2011
20110111207COMPONENT WITH A SELF-HEALING SURFACE LAYER, SELF-HEALING ENAMEL OR COATING POWDER WITH SELF-HEALING CHARACTERISTICS - A component with a self-healing surface layer, a self-healing enamel and a coating powder are disclosed. A self-healing is guaranteed by a reactive substance, which is encased in sheathed particles. Only damage to the enamel coating leads to a destruction of the coating, preferably under the influence of a catalytic material, so that the encased fluid enamel can emerge. Under the effects of UV light the fluid enamel cures and seals the crack thus occurring.05-12-2011
20110135840METHOD FOR PRODUCING A COMPONENT THROUGH SELECTIVE LASER MELTING AND PROCESS CHAMBER SUITABLE THEREFOR - A component is produced through selective laser melting of a powder material in a process chamber using a laser which is also used for producing coating areas of the component. The coating areas have a composition that differs from the composition of the powder material. This is accomplished by intermittently introducing a reactive gas that reacts with the powder material or that produces a material on the component from the precursors present in the reactive gas. In the process chamber, a feed line may be provided for introducing the reactive gas close to the laser.06-09-2011

20080217180Surface with an Anti-Adhesion Microstructure and Method for Producing Same - The invention relates to a surface comprising a microstructure that reduces adhesion and to a method for producing said microstructure. Microstructures of this type that reduce adhesion are known and are used, for example, to configure self-cleaning surfaces that us the Lotus effect. According to the invention, the surface is produced electrochemically by means of reverse pulse plating, the known microstructure being first produced and a nanostructure that is overlaid on the microstructure is produced at the same time or in a subsequent step. To achieve this for example, the pulse length of the current pulse that is used during the reverse pulse plating lies in the millisecond range and has a pulse length ratio greater than 1:3. The microstructure that has been produced, consisting of peaks and troughs is then overlaid with peaks and troughs of a smaller size order belonging to the nanostructure.09-11-2008

20100210131LATCHING CONNECTOR - A plug connector for use with electronic devices provides a latching member that engages a mating hole in a guide frame with a hook, and which can be easily delatched from the guide frame or opposing connector or housing. The hook locks the plug connector into engagement with the guide frame or housing, but is readily released by actuation of an actuator (e.g., a pulling member), which causes the latching member to translate in a vertical direction so that the hooks are lifted upward and disengaged from the guide frame or housing.08-19-2010
