摘要： 679,277. Magnetic separators. ELECTROMAGNETS, Ltd., BOX, W. E., CLARIDGE, J. T., and TURNOCK, A. G. Oct. 18, 1950 [May 12, 1950], No. 11850/50. Class 72 A magnetic separator of the belt conveyer type has a pole piece located between the conveyer runs at the place where the conveyer changes direction and separation takes place, the pole piece being associated with a source of magnetic energy located to the rear of the pole piece so that the conveyer traverses the magnetic field produced. As shown a conveyer 10 driven by a drum 11 passes over an arcuate pole piece 17 having notches formed in its outer surface in which rollers 14, projecting slightly from the periphery and supported in bearings in side plates 15, may run. A core 18a of an electromagnet sets up a field of force round the pole piece and magnetic particles 19a are separated from non- magnetic particles 19b. The electromagnet may have a pole piece from its other end lying under the top run of the conveyer to premagnetize the particles, Fig. 5, (not shown). The pole piece may be shaped partly to surround a drum which has annular strips of magnetizable material on its surface, Fig. 8, not shown).

摘要： 350,281. Magnetic separators. THOMPSON, H. H., DAVIES, A. E., and BOX, W. E., Magnet Works, Lombard Street, Birmingham. July 7, 1930, No. 20484. [Class 72.] In a magnetic separator of the trough or tray type for treating liquids or semi-liquids such as potter's slip, transverse magnetic bars e, f, g are arranged on the floor of the tray a, the upper surfaces of the bar being of convex, part-cylindrical or flattened edge section. Alternating with the bars e, f, g are magnetic bars h, j, k of similar cross section but inverted, the latter being arranged so as to leave a sinuous passage of uniform cross section for the passage of the material. The bars may be smooth or may be provided with V-grooves or corrugations; preferably the bars g, k are smooth and the others serrated. To cause the material to flow laterally as well as vertically, the bars are provided with projections l which are mounted in staggered relation to each other and may have their vertical surfaces smooth or serrated. The bars h, j, k may be detachably mounted on the sides b of the trough a, either by the provision of plugs m fitting over the sides b or being pivoted to lugs n or to a bracket p at one side of the trough. The electromagnets c are mounted in the space between the extended sides b of the trough, and supported therein by a plate d having an opening through which the space is filled with bitumen and so made watertight. The tray may be stationary or mav be oscillated and set on an incline. To prevent unseparated material being mixed with the separated material in the event of the failure of the current, magnetically controlled pivoted plates or bridges q, r are arranged at each end of the trough.

摘要： 702,905. Magnetic separators. ELECTROMAGNETS, Ltd., BOX, W. E., CLARIDGE, J. T., and TURNOCK, A. G. April 26, 1951 [April 26, 1950; July 8, 1950], Nos. 10234/50 and 17125/50. Class 117 [Also in Groups X and XXXV] A magnetic floor sweeper comprising a magnetic force-producing means within a non-magnetic drum and wheels to allow the apparatus to be propelled over a surface, has means for rotating the magnetic force-producing means relatively to the drum to remove any collected magnetic material. As shown, a non-magnetic drum 23 rigidly mounted on a yoke 241 forming the lower part of a handle 24 has passing through it an axle 21 on which are, freely mounted, a pair of wheels 20, and, rigidly attached, a plurality of permanent magnets 22 which hang vertically under the influence of gravity. A pair of arms 251 are rigidly connected to the axle and are connected at their free ends by a bar 25. Stop pins 26 limit the travel of the arms 251 in the counter-clockwise direction and movement of the bar 25 in the clockwise direction rotates the magnets, any material adhering to the drum following the magnets until removed from the surface of the drum by a shield 231. In a modification, Fig. 9, (not shown) a clutch member is incorporated so that movement of the wheels 20 in the reverse direction rotates the magnets and deposits the collected material in a box attached to the rear of the apparatus. The magnets may be electromagnets.

摘要： 591,831. Magnetic separators. ELECTROMAGNETS, Ltd., BOX, W. E., and CLARIDGE, J. T. Feb. 14, 1945, No. 3678. [Class 72] [Also in Group XXXV] In magnetic separators comprising one or more permanent magnets of, e.g. Alnico and separable magnetisable collecting means adapted to be magnetized by contact with said magnets, mechanically actuated means is provided for readily separating said collecting means from said magnets in order to facilitate removal of collected magnetic material. In one form, Fig. 1, plates 8 and' bolts 10 of magnetic material are carried by a non- magnetic U-shaped support 9, and permanent magnet 11 normally rests on said plates. Attached to yoke 11b of the magnet is screw 13 which passes freely through bridge 14 carrying depending rods 14a which pass through holes in the poles 11a of the magnet and rest in recesses in the plates 8. Separation of magnet 11 from plates 8 is effected by rotating the nut 15 to give upward movement to screw 13, which through the reaction of bar 14 and rods 14a forces the magnet out of contact with said plates. In a modification, Figs. 4, 7, a plurality of magnets 20 carried in a non-magnetic casing 21 normally make contact with the upper ends 17 of magnetic bolts attached to a plate 16 of magnetic material. Separation is effected by movement of lever handle 25 from right to left (see Fig. 7), the cam 25a thus forcing plate 16 out of contact with magnets 20. Specifications 429,199, [Group XXIII], and 557,626 are referred to.

摘要： 433,616. Magnetic separators. ELECTROMAGNETS, Ltd., and BOX, W. E., 2, Church Street, Colmore Row, Birmingham. Feb. 9, 1934, No. 4290. [Class 72] A rotary magnetic separator drum 5 comprises a central core A having radial arms 3b forming the cores of electromagnets and being of greater thickness than intermediate arms 3 , the windings 4 for the electromagnets being arranged in the spaces between the arms 3b, 3 . The material is fed over the drum by an endless belt 7 provided with blocks 8 of para-magnetic material arranged in transverse rows in staggered formation and preferably provided with toothed or serrated edges. Disposed at the rear of the drum 5 and between the portions of the belt 7 is an armature 9 having its ends of opposite polarity, one end causing the magnetic particles to adhere firmly to the belt and the other ensuring the discharge of the magnetic particles from the belt.

摘要： 251,780. Thompson, H. H., Davies, A. E., and Box, W. E. May 20, 1925. Magnetic separators.-In a magnetic separator of the trough, shoot or tray type, the material to be treated is fed over bars b, mounted on the brass or other non-magnetic bottom d of the trough &c. and directly magnetized by electromagnets c, and over 'bars a alternating with the bars b and magnetized by induction therefrom. The bars a, b may be wedge-shaped, the greater thickness of the wedges being at the lower sides of the bars, when the trough &c. is inclined, so as to form a series of steps at different levels, or the bars may be rectangular and provided with projections, grooves or serrations. Additional bars e, Fig. 3, may be mounted between the bars a, b above or spaced from the trough &c. Specification 171,859 is referred to.
