Abstract: Apparatus for the magnetic treatment of a flowing liquid, comprising a housing (1) and an annular permanent magnet (4) having radially oriented pole shoes (5, 6). Within the cylindrical space of the magnet and coaxially thereto a ferromagnetic cup member (7) is provided, which is in magnetic communication with one of the pole shoes and has slots or apertures (8) in the walls to permit the passage of liquid. The cup member (7) is provided with a radially extending collar (10) which together with the other pole shoe (6) form a magnetic field gap (11) through which the liquid shall flow. The collar (10) is part of a cap (9) adapted to be moved axially with respect to the cup member (7) to adjust the width of the magnetic field gap and thus the magnetic influence on the liquid.

Abstract: An apparatus for the magnetic treatment of a flowing liquid includes an elongated housing, which is made at least in part of a ferromagnetic material and which defines a liquid flow channel therethrough, and at least one elongated permanent magnet positioned in the flow channel. Each elongated permanent magnet has at least one elongated pole shoe associated therewith which includes a projection portion which extends into the flow channel so as to form a narrow gap between its top and either the inside wall of the elongated housing or the top of the projection portion of another pole shoe. Each projection portion is elongated in the direction of the flow channel and is angled such that the gap formed thereby is elongated and is oriented at an acute angle to the flow direction of the liquid passing through the elongated housing. The flowing liquid must pass through a formed gap and thereby be subjected to the influence of a magnetic field.

Abstract: An apparatus for magnetic treatment of a flowing liquid, such as water for the purpose of preventing precipitation of dissolved substances and corrosive effect of the liquid on the conduits and service apparatus contacted by the liquid.
