Abstract: An apparatus for separating ferromagnetic materials from fluid media has a working passage divided by a partition into sections filled with an insert of ferromagnetic material. A magnetizing system is arranged coaxially with the working passage. An arrangement for imparting reciprocations to the magnetizing system is fashioned as at least two electromagnetic coils with one such coil at the opposite ends of the passage, parameters of the coils being such as to ensure movement of the magnetizing system between two extreme positions.

Abstract: Disclosed is an apparatus for separating ferromagnetic materials from fluid media which has stationary chambers containing a ferromagnetic filtering packing capable of being magnetized. The chambers, arranged pairwise, are provided with a self-contained means of magnetization, the magnetic circuit whereof comprises two opposite sections which are located on either side of a line through the centers of the chambers. Each of the sections is made up of a magnet and pole pieces arranged next to the chambers at the diametrically opposite ends of a line at right angles to the center line referred to above so that the two sections form a closed magnetic circuit in conjuction with the ferromagnetic packings.

Abstract: A separator for magnetical removal of solid particles from fluid media comprises a flow chamber filled with a rod-type ferromagnetic orienting packing, and a magnetic system for magnetizing the packing. The packing rods are arranged along the flow of the medium being purified and contact each other over lateral surfaces thereof.

Abstract: A predetermined quantity of the fluid to be analyzed is made to pass through magnetized filtering packing, and the content of the solid fraction is measured after the exit of the fluid from the packing, before its re-entry into it. Recirculation is continued until a permanent, unvarying residual content of the solid phase in the fluid is attained. The fluid subjected to the recirculation is periodically acted upon by an alternating magnetic field, outside the packing.
