Title: Means for conveying liquid metal from a reservoir in an electromagnetic conveyor trough to an elevated position
IPC: B22D39/00
Filed: 1971-12-01
Abstract: 1327972 Discharging molten metal AEG-ELOTHERM GmbH 1 Dec 1971 [10 April 1971] 55785/71 Heading F4B An inclined conveyer for discharging molten metal from a reservoir 1, e.g. a hearth containing molten pig iron or steel, includes a first linear travelling field inductor 5 disposed beneath its refractory channel at its lower end adjacent the reservoir and a second linear travelling field inductor 14 disposed above its channel over the remainder of its length. The upper end of the lower inductor is located at least one pole pitch above a point 9, this being the highest point reached by metal in the conveyer when the level in the reservoir is at its maximum and the inductor 5 is switched off. The conveyer is arranged so that there are no discontinuities in the thickness of its refractory lining at the two ends of the lower inductor. The volume flow of metal is controlled by varying the field intensity of the lower inductor while maintaining that of the upper inductor substantially constant.

Title: Method of and apparatus for fabricating high strength fibre-reinforced sheets or mouldings provided with holes, slots or other apertures
Inventor: KARGER WALTER
IPC: B28B3/00

Abstract: 1,224,786. Moulding perforated reinforced articles; perforating sheet material. G. JANNE 25 Nov., 1968, No. 55873/68. Headings B5A and B4B. High strength, reinforced, perforated articles e.g. building elements are made by perforating a fibrous fleece by a device carrying mandrels, transferring the fleece from the device on to a mould having upstanding cores adapted to accommodate the perforations in the fleece and finally impregnating and moulding the fleece to the desired shape. The moulding may comprise impregnating the fleece, with or without additional compression, by mere casting or may comprise injecting the impregnant. In the example illustrated in Fig. 1, a glass fibre fleece 1, which may or may not be pre-impregnated, is located upon an apertured plate 4 to which suction is applied and is perforated by means of mandrels 9 carried by plates 16, 17 and 18 themselves carried by springs 19 from a plate 20. Penetration of the mandrels is assisted by imposing a circular movement upon plates 16-18 by a motor-driven eccentric pin 24. After perforation the perforating device 3 is located over a mould 2 having cores 25 and the fleece transferred to the mould by stripper plate 26. Accurate transfer is facilitated either by telescopically mounting the pointed tip of the mandrels upon their cylindrical bases so that upon contact of the tip with the cores they are forced back into the bases, or by making the tips integral with the bases and accommodating the tips during the transfer in bores located in the cores, which bores may be filled with a resilient material. After transfer of the sheet, the device 3 is withdrawn, a wire mesh placed upon the fleece and plaster poured thereon, the mesh acting to prevent splashing of the plaster over the tops of the cores. In an alternative embodiment (see Fig. 6), the mould is mounted on a mould box 36 covered by lid 35, and plaster injected into the fleece through opening 38. After injection the mould is removed from the mould box by compressed air through bores 39, and the moulding subsequently removed from the mould. In a further embodiment (see Fig. 7), the fleece is located in a mould comprising an outer frame 4 and a centre section 41 through which rigid cores 27, externally supported by a rubber plate 29, project, and is impregnated with plaster. Pressure is then applied through a resiliently lined cover-plate 43. After moulding, the coverplate is withdrawn and the moulding freed from the centre section by reciprocated striker bar 44. The moulding together with frame 4 is then lifted clear of the centre section and the moulding finally removed from the centre section.
