Abstract: A system for non-destructive determination of the degree of fluorination in carbon monofluoride (CFx) during the process of CFx synthesis is described. The system includes a measuring generator containing a capacitive sensor for measuring a respective capacitance, a base generator containing a capacitive sensor for measuring a base capacitance, and a processor for determining a difference between the respective capacitance and the base capacitance. The system is configured to determine the degree of fluorination based on the difference between the respective capacitance and the base capacitance.

Abstract: The present invention is a method and apparatus for optical detection and size evaluation of through-penetrating defects such as pinholes in moving foil or film. The invention comprises the installation of at least one image capture device at a first given distance over the moving foil surface, placement of at least one elongated light source comprising an infinite number of point-sources that are not in phase, and are emitting light independently from one another under the foil, periodic automatic computer-controlled image capture of the foil surface with image capture devices, automatic transmission of the image captured by each device to a control computer, and processing of the transmitted image data to detect of defect light spot, followed by determination of generalized index of its initial image. This generalize index value is equal to the brightness averaged within the spot multiplied by the area of the spot.

Abstract: A method of non-destructive testing for quality control of powdered materials having dielectric properties based on the use of electromagnetic capacitance techniques.

Abstract: Method and related device intended for rapid non-destructive testing of powdered materials with low electric conductivity such as cement and cement-based compositions through determination of their electrical properties. The invention involves an electromagnetic method, including an electronic circuit for generating an electric field in a capacitance probe that is inserted into the powder to be tested. Electrical properties of powdered materials are determined on the basis of a set of the values for a set of parameters including quality factor (Q-factor), capacitance, dissipation factor, and dielectric permeability of the material. These parameter values can be related to such characteristics as moisture content, particle size, and material composition. The method and device can indicate the differences between the samples with various quantities of unwanted components or reaction products, and the extent of sample aging.
