A magnetic scanning coil deflection system, e.g. for a cathode ray tube, comprises at least one pair of coils having longitudinal segments and provided with forward transverse, cross-over segments 34b, 36b which are distributed in a longitudinal direction over an outwardly flared portion 22 of a former 10 so as to produce a curved magnetic field whose flux lines bow outwardly and are generally perpendicular to the electron beam as it is deflected. A second pair of coils is similarly provided on a second former 12 and the system has a ferrite jacket 14 with a flared and protruding forward end 90 and also a protruding rear end 92. A non-magnetic spacer 70 is fitted between the ferrite jacket and the former 12. The coils are rectangular spirals with the longitudinal segments distributed in slots in the formers 10, 12 in accordance with a sine function modified to compensate for the longitudinal distribution of the cross-over segments. The coils may be formed as etched thin films bonded to the formers. The flared portion of the system may be extended back to constitute the major or entire portion of the system.

Abstract: 1,086,094. Continuous casting. UNITED STEEL COMPANIES Ltd. Nov. 19, 1965 [Nov. 24, 1964], No. 47823/64. Heading B3F. In a method of continuous casting in which the molten metal is poured from a tundish 1 into a reciprocating mould 4 means are provided for connecting the tundish to the mould so as to form a chamber through which the molten metal passes and which contains a reducing or an inert gas. The chamber comprises a cooled upper part 13 attached to the tundish and lower part 15 which is attached to the mould and an intermediate part which effects sealing engagement between the ports 13 and 15. The seals 20 permit the axial reciprocation of the mould and the seal 21 permits adjustment of the port 13 transversely of the mould. Prior to the pouring of the metal reducing or inert gas is introduced into the chamber through passage 24 to purge the mould and chamber and is subsequently supplied during the casting operation. The gas pressure during casting is maintained substantially atmospheric by controlling the gas supply through passage 24 and the escape through passage 25 in conjunction with the level of metal in the mould. The choice of gas used in the process depends on the nature of the material being east and include propane, butane, nitrogen etc. or suitable combinations of such gases and whereby oxygen concentration in the chamber is not greater than 250 parts per million. In a further embodiment. Fig. 6 (not shown) part spherical seaitings are provided on the upper and lower ports of the chamber member to facilitate slight angular misalignment of the tundish and the mould for example by tilting of the tundish or by reciprocation of the mould in an arcuate path, when a curved mould is used.
