On a column 24, arm pairs 23 and 28 are independently swivelled. Each pair carries a tray 22 or 26 for bearing a tundish 21 or 27. The tundish 27, deposited by the crane 4 on its tray 26 in a position 25, can be swung to a preheating position 29 whilst the tundish 21 is in casting position as shown. Then, at a charging station 30, some metal from the ladle 31 can be teemed into the preheated tundish 27 so that, as soon as the tundish 21 is swung to position 25 for removal by crane, the charged tundish 27 can be swung to the vacated casting position to maintain flow to the mould 10. In another embodiment, the tundishes (55, 56) are borne on single arms swivellable about a column (54), and by power means each tundish can be moved on arcuate rails 58 on its arm to swing about the axis of its outlet nozzle (59). Then the receiving end of the operating tundish can be swung from beneath an emptied ladle (61) to beneath a full ladle (62) whilst still feeding the mould from its nozzle. The ladles may be stationary, on trestles. In a further embodiment, swivel arm-pairs (42, 43) are mounted on separate columns (44, 45) between which is the casting position of either tundish, a plane containing the column axes being perpendicular to the tundish length when it is in that position.

Abstract: 1,193,558. Voltage protection arrangements. ALLMANNA SVENSKA ELEKTRISKA A.B. 5 Nov., 1968 [6 Nov., 1967], No. 52367/68. Heading H2H. A voltage protection arrangement for A.C. or D.C. systems comprises a plurality of parallel branches, each containing non-linear resistors and spark-gap stacks. Cross impedances between the branches ensure that all branches take part when discharge occurs, and arc extinction is aided by magnetic extension. In operation, assuming the branch 1 ignites first, the voltage drop across the stacks 6, 7 will initially be very low, and most of the drop in the branch 1 will be across the non-linear resistor 5. By way of the impedance 8, this voltage is applied to the stack 7 of the next branch 2, igniting first this stack, and then the other stack 6. Similarly, branches 3, 4 ... are successively ignited. In the meantime, the arcs in branch 1 have been extended until the impedance of this branch rises to the point where extinction occurs. Now, the voltage across the non-linear resistor 5 in the branch 2 will raise the voltage across the stack 6 in branch 1 until re-ignition eventually takes place. In this way, repeated ignition and extinction takes place in each of the branches while the over-voltage condition persists.

Abstract: 1319870 Crystallizing from a melt MONSANTO CO 16 Nov 1971 [17 Nov 1970] 53129/71 Heading BIG An organic compound having a melting point above 0‹C at one atmosphere is separated from a molten mixture having zero or low solubility in water and in which the compound is present with one or more organic compounds, by crystallizing the compound from the melt in the presence of water, and separating crystals of the compound from the melt liquor. A minor amount of a caustic compound may be present during crystallization. The mixture is preferably a mixture of isomers, e.g. a mixture of nitrochlorobenzenes from which p-nitrochlorobenzene is separated. The crystallisation is effected by feeding the molten mixture into a crystallizer containing water and the caustic compound, to a level just above a stirrer, withdrawing the slurry and separating the crystals by a centrifuge. The crystallizer and centrifuge are maintained at an elevated temperature to prevent solidification of the melt.
