A magnetic separator comprising a feed hopper for a raw material to be separated, chutes for separating and discharging respectively the concentrate and the tailing magnetically separated from each other, a rotary drum incorporated in the casing and having separation walls of a non-magnetic material disposed on both sides thereof and forming therebetween at least one feed separation passageway extending from the feed hopper on the rotation side of the rotary drum up to the discharge shoots, and ...

A magnetic structure for the propagation of magnetic bubbles at elevated velocity. A magnetic bubble layer is grown on a [110] face of a substrate, the lattice misfit being between -6.times.10.sup.-3 and -2.times.10.sup.-3, and the magnetic layer having a composition on the basis of europium-iron garnet and a damping parameter .ltoreq.3.times.10.sup.-7 Oe.sup.2 sec/rad.

The drive uses a recessed wall or partition between the pole-rings of the two rotors to substantially diminish the occurrence and strength of eddy currents. The recesses may be in the form of grooves, depressions or axial bores which reduce the mass of the wall. The wall is further reinforced by non-magnetic electrically non-conductive or insulated elements of high tensile strength to compensate for the reduction in strength caused by the grooves, depressions or bores.

A magnetic switch has a substantially closed casing. A conductive plate with an electrical contact is fixedly mounted in the casing. Another conductive plate has an electrical contact mounted thereon and is mounted inside the casing for pivoting or sliding movement. Magnetic members, such as permanent magnets, one on the movable plate and one outside the casing urge the movable plate to a contact engaging position when the outside magnetic member is brought proximate to the casing, and a spring ...

A rotor and base, rotatingly connected, are each provided with a plurality of magnet assemblies. The magnet assemblies on one of the rotor and base are fixed and the magnet assemblies on the other of the rotor and base are moved radially in synchronization with the rotation of the rotor to produce a torque on the rotor.

A magnetic flowmeter whose electromagnet is excited by a low-frequency excitation current, the flowmeter including flow tube electrodes yielding a flow rate signal. A reference voltage-detecting transformer is provided in the excitation circuit to produce a reference voltage that reflects fluctuations in the excitation current. Fluctuations in the flow rate signal as a result of fluctuations in the excitation current are eliminated by dividing the flow rate signal by the reference-voltage signal...

A magnetic alloy of the Fe-Cr-Co type having superior magnetic properties compared to those of the conventional magnetic alloys of this kind and consisting essentially of, by weight, 5 to 30%Co, 15 to 35%Cr, 0.1 to 10%Ti, 0.1 to 10%V, 0.005 to 0.03%C, 0 to 0.1%Al, and the balance being Fe. The magnetic alloy according to the present invention may further contain 0.1 to 5% of one of the elements selected from the group consisting of W, Mo, Zr and Ta.

A magnetic relay having an electromagnetic coil with an open center extending lengthwise therethrough and an outer tube of magnetic material enclosing it lengthwise. A pair of radially expandable disks of magnetic material are positioned in the outer tube across the ends of the coil and a pair of inner tubes of magnetic material are positioned axially aligned with each other through the central openings in the disks and in the open center of the coil about a switch contact, e.g. a reed switch ca...

A process is disclosed for separating a relatively more magnetic material from a relatively less magnetic material comprising passing the material being processed through a plurality of regions, each region having a relatively more magnetic segment and a relatively less magnetic segment, such that the plurality of regions are arranged so as to comprise alternating relatively more magnetic and relatively less magnetic segments, which regions are aligned at an angle other than 90.degree. in the pl...

Disclosed is a magnetic head used for a vertical magnetizing system comprising a core having a pair of leg portions and an auxiliary magnetic pole which is arranged so as to face both leg portions. A closed magnetic path is formed by the core and the auxiliary magnetic pole. A sharp edge is formed at each end of the leg portions. A magnetic recording medium passes through the gap between the sharp edges and the auxiliary magnetic pole. When the magnetic recording medium passes through the gap, a...
