Patents by Inventor Alexei E. Novikov

Alexei E. Novikov 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).

  • Magnetizing device with yoke having loosely fitted coil sections for magnetographic inspection of quality of materials
    Patent number: 4884028
    Abstract: A device for magnetographic quality inspection of a material, whereby a magnetic-recording medium is applied onto the material to be inspected, and they are together magnetized so that the resulting magnetogram can be used to assess the quality of the material. According to the invention, the intensity of the magnetizing field is established by the maximum curvature of the surface of a drop of a magnetic fluid applied onto the surface of the material to be inspected. A magnetic substance is placed between the magnetic-recording medium and the material so that the surface of the latter is smoothed out. The magnetizing device includes a magnetic yoke and a magnetizing coil loosely fitted thereon and composed of sections which are connected in parallel to one another.

  • Magnetizer having a main electromagnet and leakage flux reducing auxiliary electromagnets for magnetographic inspection
    Patent number: 4835470
    Abstract: A magnetizer for magnetographic inspection of articles comprises a main electromagnet, an auxiliary electromagnet, and a power supply unit for the windings of the electromagnets. The auxiliary electromagnet is offset with respect to the central zone of the magnetic field established by the main electromagnet, in a direction perpendicular to that of the magnetic lines of force of the main electromagnet, and is mounted for changing its position.

  • Magnetizing device for recording flaw fields in the process of magnetographic inspection
    Patent number: 4743849
    Abstract: A magnetizing device includes a two-pole electromagnet with four rollers mounted in pairs on the poles of the electromagnet and interacts with a respective guide. These guides are made as rings. The rollers are mounted on the poles by means of half-axles which are secured on each roller with a displacement in relation to the rotation axle of the roller.
