Abstract: This invention provides an improved apparatus for the treatment of water to reduce the formation of scale in those mechanical devices that employ water and to enhance the service ability of liquids in other applications through the use of magnetic circuitry which maximizes the effectiveness of the magnetic flux upon fluids. The circuitry includes flat-ring true permanent magnets, collector disks with tapered transmission points, set air gaps and threaded concentrator cores. This invention makes it possible to tailor magnet spacing to meet a wide range of velocity and flow rate requirements through the use of flux separators of varying sizes and the interchangeability of the inner core.

Abstract: An eddy current magnetic ore concentrator, using parallel cup cores, where an alternating and direct independent field with phase offset removes and sorts metallic ore components from ferrous and nonferrous ore, where the metal may be in solution or the native form.

Abstract: A substantially cylindrically shaped rubber food scraper is mounted on a steel dish cleaning table over a refuse container located below the table. The interior of the scraper is substantially hourglass shaped and includes a plurality of magnets embedded in the interior wall thereof adjacent the reduced diameter portion. Food and waste paper scraped from dishes pass through the scraper to the container below but stainless steel flatware is attracted to and held by the magnets.

Abstract: Magnetic and non-magnetic materials are separated by passing stream thereof past coaxial current-carrying coils which produce a magnetic field wherein intensity varies sharply with distance radially of the axis of the coils.

Abstract: The electromagnetic separator comprises a cylindrical housing with a conical bottom, a circular electromagnetic system embracing the separator housing on the outside, a cylindrical pulp feeding device with a paddle agitator, a system of disks, a wash water feeding device, a nonmagnetic product discharging device and a magnetic product discharge branch.In order to increase the efficiency of separator operation by providing the appropriate hydrodynamic conditions of pulp flow, the separator comprises a system of disks with holes. The disks are spaced apart and installed one under the other directly underneath the pulp feeding device. The bottom disk is provided with a wash water feeding device constructed in the form of a circular element with tangential branches, there being a gap around the outer side of said circular element.The paddle agitator is located inside the bottom part of the pulp feeding device whose top part is provided with tangential branches.

Abstract: A process and apparatus for separating magnetic particles from an ore material whereby an ore material intermixed with a liquid or gaseous carrier is fed through a separating zone acted upon by a magnetic field generated by a superconducting solenoid magnet. During passage through the separating zone, the magnetic particles in the ore material are attracted toward the periphery of the zone while the nonmagnetic particles substantially remain at the center whereupon each is then separately collected by mechanical means.

Abstract: Waste paper is fed into a horizontal drum and therein treated with suitable liquids to form pulp. A magnetic device is disposed adjacent one side of the drum to produce a magnetic field along one arcuate section and extending from the upper portion toward the bottom thereof. Magnetic particles mixed with the paper are carried by said arcuate section of the drum by virtue of the influence of the magnetic field until they reach the top where they leave the field and then fall downwardly into an inclined trough from which they gravitate to the exterior of the drum. Pulp is concurrently discharged from the drum.

Abstract: A magnetic filter element comprises a rubber bonded barium ferrite permanent magnet strip enclosed in a thin, liquid impervious, non-magnetic envelope and positioned in a low velocity location in a fluid system to capture magnetically attractable contaminants. The disclosure illustrates various arrangements of the magnet with filter cartridges as well as the construction of the magnet element itself.

Abstract: A multiple matrix assembly for a magnetic separator including a container; a plurality of magnetic matrices arranged in a longitudinal stacked array in the container; each matrix having a feed area and a collection area on opposite longitudinal ends transverse to the longitudinal axis of the container and the flow through it; and having a peripheral portion surrounding it and extending longitudinally between the feed and collection areas, the matrices being disposed with the feed areas all facing in a first direction and their collection areas all facing in a second direction; inlet and outlet means in the container for feeding to and collecting from the matrices; and receptacle means, disposed between each pair of adjacent matrices, each of the receptacle means including a transverse member proximate and coextensive with a one of the feed and collection areas and a peripheral member extending longitudinally in one of the first and second directions from the transverse member along and sealingly engaged with

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.
