Patents by Inventor Ivan V. Maximov

Ivan V. Maximov 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).

  • Electrochemical working method and system for effecting same
    Patent number: 4257865
    Abstract: The electrochemical working method according to the invention comprises the use of two electrodes whereof one oscillates with respect to the other. Voltage pulses are applied to the electrodes in synchronization with the oscillation and are continued to be applied thereto when the electrodes are found at a minimum distance from one the other. As the electrodes are brought apart, cavitation is produced in the interelectrode gap, which phenomenon is accompanied by a change in the relative resistance of the gap. A cavitation transducer is used to measure a parameter which unambiguously determines the cavitation intensity corresponding to a preset minimum gap. In order to control the electrochemical treatment process, a comparator produces a signal equal to the difference between a signal corresponding to the actual relative value of the parameter function and formed by a computing unit, and a signal corresponding to a predetermined value of the parameter.
    Type: Grant
