摘要： 430,445. Electromagnets. ELECTROMAGNETS, Ltd., and BOX, W. E., 2, Church Street, Colmore Row, Birmingham. Feb. 9, 1934, No. 4289. [Class 35] An electromagnet is provided with polepieces each having several differently formed edges, and so arranged that different edges of the two polepieces can be made to face each other so as to give fields of different characteristics. The Figure shows polepieces 11 each having one flat edge and one toothed, one with a salient obtuse angle and one with are -entrant angle. The polepieces are secured to the cores by screws 9, about which they can be turned.

[Class 72.] The upper drum g of an elevator a provided with buckets d is constructed as a magnetic drum so that the magnetic material is retained in the buckets and discharged at a point q, the non- magnetic material being discharged at p on to an oscillating or reciprocating sieve c. The bottoms of the buckets d may be provided with projecting feelers or fingers of magnetic material and the buckets may be made in two portions connected by a strip of non-magnetic or like material. Alternatively pairs of buckets placed side by side on the elevator may be used.

摘要： 318,786. Thompson, H. H., Davies, A. E., and Box, W. E. Oct. 31, 1928. Magnetic separators. - The magnet core g provided with windings h is secured to the under side of a bar f which is mounted on the flat tops of collars e mounted on the spigot portions d of fixed stub axles c on which rotate the ends b of a rotary drum a. Secured to the bar f is a bar or shoe j which is curved to conform to the surface of the drum a and provided with a projection k which extends between two spaced fingers l on a pole-piece m secured to the lower end of the core g. The magnet system is completed by n rectangular plate n secured to the bar f and which terminates in a curved lower edge p forming a pole shoe closely adjacent to the drum

摘要： 227,019. Thompson, H. H., Davies, A. E., and Box, W. E. March 24, 1924. Magnetic separators.-In a process for separating fuel from furnace residues, ashes &c. the material to be treated is passed over a surface which is under the influence of a magnetic field and a powerful air current is positively directed. on to said surface to assist in the separation of the magnetic particles. The material is. fed on to a belt a passing over a magnetic drum or pulley b and an air current is directed on to the belt a from an arcuate cowl d secured to the upper end of a duct f mounted on a centrifugal fan e, the current being controlled by a valve f . Before separation, the material may be ground. to such a degree of fineness that the fuel and the slag &c. are rendered mechanically independent, and the separator may be provided with two or more fields of different intensity so that the. non-magnetic, the feebly magnetic and the strongly magnetic materials may be received in separate receptacles such as m, n and p. Speci. fications 150,333 and 152,642, [both in Class 50, Fuel, Manufacture of], are referred to.

摘要： 433,458. Magnetic separators. ELECTROMAGNETS, Ltd., and BOX, W. E., 2, Church Street, Colmore Row, Birmingham. Feb. 9, 1934, No. 4291. [Class 72] In a magnetic separator of the trough or tray type, inclined flaps or baffles 8 of para- or dia-magnetic materials are arranged above pole pieces 6 of electromagnets 5 so as to intercept pieces of material which may ricochet from one of the polepieces. The flaps or baffles 8 are pivotally mounted on pins 7 and rest on supports 9 which are carried by pins 9 and can be locked in any desired position. The lower edges of the flaps or baffles may be serrated.

摘要： 236,758. Thompson, H. H., Davies, A. E., and Box, W. E. Aug. 25, 1924. Magnetic separators.-In a separator pulley, magnet windings d, Fig. 1, in the form of separate units are carried on cores e arranged longitudinally between steel or other rings c which are mounted on and carried by the stepped peripheries of rings b, of brass or other non-magnetic material, secured to a shaft a. The spaces between the outer edges of the rings c is filled with strips of brass or other non-magnetic material, secured to shoulders g on the rings c to provide a smooth surface for the pulley belt. To ventilate the pulley, air enters the latter through apertures j in the strips f and leaves by apertures (not shown) in the rings b. The circulation of the air may be assisted by a fan rotatably mounted on the shaft a. In a modification, Fig. 5, spiders m of non-magnetic material are mounted on a stationary shaft a. Segmental pole-pieces w which extend for slightly more than 180‹ and carry the cores &c. o mounted on the spiders m. The cores c &c. are mounted inside a rotary dum k having a non-magnetic periphery q. The poles n may extend beyond the cores o or an adjustable armature may be arranged close to the drum to concentrate the lines of force. In another modification the pole pieces are provided with inwardly, directed or cranked flanges, the space between the poles being closed by a non-magnetic strip. The surfaces of the flanges may be serrated, grooved or, ribbed. When this form is used with a drum, as in Fig. 5, the non- magnetic periphery is provided with a groove fitting between the flanges of the pole-pieces and into which the material to be treated is fed. Continuous or broken rings or bars, or studs or feelers of magnetic metal may be secured on the outer surface of the drum. Specification 5522/07 is referred to.
