Vladimir Iosifovich Tsvetkov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9561528
    Abstract: The invention relates to the area of mineral processing, and more particularly to separation of crushed mined material containing minerals, which are luminescent under the action of exciting radiation, into products to be concentrated and tailing products. The invention can be implemented both in X-ray-luminescent sorters at all beneficiation stages and in product inspection devices, like diamondiferous raw materials testing.

  • Patent number: 9068892
    Abstract: The proposed method is related to the field of physics and atomic emission spectrometry analysis. This atomic emission analysis method includes initiation of a local electric discharge in the liquid under analysis with the formation of a current-carrying channel in the volume of a diaphragm opening made in a member of the electrolytic cell structure, and detection of the generated emission spectra of the chemical elements being determined. The elements being determined are first deposited in the current-conducting channel volume at current insufficient for initiating a local electric discharge, then the current direction is changed and its intensity is increased for initiating a local electric discharge, and emission generated in the liquid being analyzed is detected as emission spectra of the elements being determined. The deposition current intensity can be selected according to elements to be determined and their concentration in the liquid.
