  • Patent number: 8262803
    Abstract: A method for cleaning cavities in workpieces, a cleaning device for this purpose and a device for the supply of media to a cleaning device of this type. Supercritical carbon dioxide is introduced into the cavity and the cavity is rinsed. The supercritical carbon dioxide located in the cavity is relieved of pressure after rinsing of the cavity, so that carbon dioxide gas and carbon dioxide snow are formed in the cavity and subsequently driven out of the cavity.

  • Patent number: 6532065
    Abstract: The invention relates to a device (1) suitable for controlling a surface (8) of an object (7), notably with respect to raised areas on said surface (8). The device (1) comprises a light source (2, 3) for generating a light beam (5, 6) directed towards the surface as well as a light sensor (4) for detecting light scattered by a raised area on the surface (8). The light beam (5, 6) generated by the light source (2, 3) is configured so as to scan the surface (8) in such a way that the raised area on the surface scatters the light beam (5, 6). If there is no raised area the light beam (5, 6) undergoes ideally no, or else only slight, changes. The light sensor (4) is arranged in such a way that at least part of the scattered light can be detected. In this manner it is possible to detect, for example, impurities on uneven or structured surfaces.

  • Patent number: 6337739
    Abstract: The invention relates to a method and a device for quantitative and qualitative on-line differentiation of biotic and abiotic particles. The methods and devices are used to ensure quality and to monitor production as well as in analysis procedures for particular contamination's of gaseous media. The methods and devices are chiefly used in pharmacology, food technology, medicine, biotechnology and health care and in controlling maximum admissible concentration values. According to the inventive method, the gas sample to be measured is briefly heated at very high temperatures in a heating chamber (3). Dimensional distribution of particle contamination is determined before and after heating by means of diffuse light sensors (1, 2). Dimensional changes of biotic panicles caused by heating make it possible to determine their proportion in total particle load of the gas sample and their composition.
