Title: Process and Apparatus for the Continuous Casting of Ingots from Molten Metal
IPC: B22D11/11
Filed: 1967-08-24
Abstract: 1,190,059. Continuous casting. ALUMINUM CO. OF AMERICA. 24 Aug., 1967 [1 Sept., 1966], No. 39086/67. Heading B3F. Casting rate and ingot quality of Al or Al alloy is said to be improved by a heat-insulated displacer 68 in an open-ended chill mould 10, e.g. inserted after continuous casting has been started. In the case of the vertical mould shown, continuous casting is started by lowering a mould closure plate (102). The drum- or box-shaped displacer is lowered by a rack 46 and pinion 42 rotated by a handle (50) and shortens the molten core. Water is directed from a pipe 98 on to both the (graphite or aluminium) mould 10 and the casting 100. The mould is topped by a box or ring 14 comprising fire-brick or asbestos-silica insulation (like that 86 of the hollow and uncooled displacer 68), possibly in compressed sections 16, in a steel shell 18 secured to a flange 12 on the mould. Melt enters the insulated mould top 14 from one or more troughs 96. The insulated displacer 68 is withdrawn from the mould 10, into the top 14 or above, before casting is started. To determine thermal conditions, thermocouples (94) are mounted in the displacer 68.

Title: Wrapped yarn and process and apparatus for the preparation thereof
IPC: D01H1/11
Filed: 1965-09-15
Abstract: A yarn wrapped by fibres is produced by drafting strands of the fibres to produce loose fibres which are forwarded in an air stream to the point of convergence of at least two continuous core elements, and false-twisting the core elements so that the twist runs back to the point of convergence and the fibres are combined with but not highly twisted with the core elements, but that on reverse-twisting the core elements to remove their twist the fibres are tightly twisted about the core elements with portions of the fibres locked into place between the core elements.  A suction box - Fig. 1, not shown - is arranged immediately downstream of the drafting rollers and has holes through which the drafted fibres, core elements, and the composite yarn pass.  The false-twist device-which may be a fluid jet as in Specification 976,478 - is situated outside of the box. The core elements may be mono- or multifilament, or staple fibre yarns, or mixtures of continuous filaments and staple fibres, or core spun yarns.  The fibres may have a length of up to 20 inches or longer.  The core elements and wrapping may be composed of any natural or synthetic fibre of which many are listed and include spandex, metal, glass, asbestos and multi-component fibres.
