A magnetic separator comprises a housing 1, of non-magnetic material, having axially aligned liquid-inlet and outlet ports 3, 4 at respectively opposite ends, and a solid circular cylindrical magnetic body 2 formed at least in part of permanently magnetized material disposed in coaxial alignment with the ports to define an annular flow passage with the casing walls, the body 2 being supported in the housing at each end by a conical flow-diffusing member 11 which is secured to the housing and tapers from the body towards the ports. As shown, the body 2 comprises unitary or built-up sectored discs 18 of magnetized barium ferrite ceramic material axially separated and flanked by discs 19, 20 respectively of ferro-magnetic material which each have circumferential spaced peripheral recesses 21 filled with non- magnetic solder. The discs 18-20 are adhered together on a rivet 22 and the assembly has axial end projections 9 by which the body is supported in grooves 10 in the facing surfaces of the elements 11. Removal of the body 2 is effected through an opening, in the housing, which is normally closed by an inner cap 6 held on a seating by an outer screw-cap 7. The body 2 is captive in the inner cap by means of a headed pin 14 extending from the body into a two-part bore 14, 16 in the cap 6. In an alternative arrangement, the inner and outer caps 6, 7 are replaced by a simple flanged lid secured by bolts pivoted on the housing. Each diffusing element 11 is secured to the housing by fins 12 as shown, or alternatively, by a pin extending transversely through the element with its ends located in opposite sides of the housing, or by a plate which is bolted or stuck in a slot in the end of the element and is located in diametrically opposed slots in the adjacent port 3 or 4.  In operation, particles attracted to the exposed portions of the peripheries of the discs 19, 20 build up to serve as a mechanical filter. A separate mechanical filter in the form of a coil spring may be housed in a circumferential groove in the body 2 to project into the flow-path, or a mesh filter 23 may be carried by the body. In a further arrangement, Fig. 9, a fibre band 38 carrying thin steel splines 40 may be housed in a circumferential inner peripheral recess 39 in the housing so that the splines approach or touch the disc 19, across the flow-path, and are magnetized thereby. A further band 41 of fibre, copper, or rubber serves for cleaning of the splines on removal of the assembly 38, 40 from the housing. In a further construction of the body 2 the separate discs 18-20 are replaced by a number of composite discs each formed from sectors of the ceramic material spaced by radial plates of ferro-magnetic material, the discs being assembled coaxially with their respective plates circumferentially staggered longitudinally of the assembly.

Abstract: 1,174,849. Continuous casting-machines; making billets. CONCAST A.G. 20 Sept., 1967 [21 Sept., 1966], No. 42799/67. Headings B3A and B3F. In the continuous casting of steel castings the strand is withdrawn from a mould having a cross-section that differs from that of the desired final casting, and whilst still having a molten core the strand is plastically deformed, e.g. by shaped rolls, to produce a square or circular section billet in such a way that the difference between the areas of the provisional cross-section and of the billet exceeds the crosssectional area of the molten metal displaced from the core. The provisional cross-section produced by the mould is polygonal and oblique-angled or circular and, in the example described, is a rhombus. The strand may be cooled between the mould and the deforming means with less cooling in the acute-angled region of the rhombus that in the obtuse-angled region. In a casting plant where the strand is passed through deflecting guideways, the strand may be simultaneously plastically deformed and bent. The strand may be heated before it passes through the shaped rolls.
