Title: Electroslag refining process
Inventor: HOYLE GEOFFREY
IPC: B22D23/10
Filed: 1971-10-15
Abstract: 1338061 Casting processes and moulds BRITISH IRON & STEEL RESEARCH ASSOCIATION 15 Oct 1971 [15 Oct 1970] 48931/70 Heading B3F An electroslag refining process for casting ingots with a change of cross-section along their length uses a mould comprising upper and lower sections 4, 5, the diameter of the lower section 4 being greater than that of the upper section 5, and the upper section 5 depending into the lower section 4 with a space between opposing walls of each section. When casting an ingot for a roll, a mould including a cooled base-plate 3 surmounted by three cooled mould sections 2, 4, 5 is employed and the process commenced by fusing a consumable electrode 9 into a molten slag bath 8 in the lowest mould section 2. When the molten metal level 10 reaches the centre mould section 4 additional slag is added to the slag bath 8 to maintain a constant depth of molten slag. The additional slag is supplied as powder retained in the centre mould section 4 by a tube 7 of material destroyed by the molten slag, or as a liquid through an aperture in the mould wall (not shown). An annular electrode 13 or a circular array of rods (not shown) is/are fused down with electrode 9 into the centre mould section 4. As the molten metal reaches a level B-B in the centre mould section 4 fusing down of electrodes 9, 13 is stopped and the upper mould section 5 is lowered into the slag bath 8 to displace excess slag into the space between the upper and centre mould sections, where it can be frozen by a chill plate (not shown). To complete the ingot the electrode 9 is fused down into the upper mould section 5. In an alternative embodiment, the lower section 2 of a similar 3-section mould is provided with a baseplate movable between the top and bottom of the lower section. At start-up of the process the base-plate is located at the top of the lower section and an electrode fused into a slag bath in the mould centre section 4. As refining proceeds the base-plate is lowered so that molten metal runs into the lower section 2 of the mould. A further modification involves the use of a preformed electrode with a centre-section of increased diameter compared with its upper and lower sections, which is fused down into a 3- section mould.

Abstract: 1378589 Uses of luminescence EASTMAN KODAK CO 26 Oct 1972 [26 Oct 1971] 49533/72 Heading C4S An organic luminescent material is quenched by an applied electric field. The material is a rare earth methyl-#-diketone chelate having a structure where Q<SP>n</SP><SP>+</SP> is a cation of valence n, where n is an integer from 1 to 6, e.g. Li, Na, K, Rb, Cs, Be, Mg, Ca, Si, Ba, NH 4  and substituted amine and ammonium radicals; M is a metal of atomic number 57 to 71 and 89 to 103; R, R<SP>1</SP> and R<SP>11</SP> are alike or different hydrocarbon radicals including fluorocarbons, having up to 12 carbon atoms. R<SP>1</SP> can also be H, Cl, Br, I or cyano radical. The radicals may be substituted with a halogen, ether thioether. The chelate is in solution with, e.g., methanol, benzene or tetrahydrofuran. Salts to increase conductivity may be added, e.g. benzyl trimethyl NH 4 I or tritylium perchlorate. A large number of examples are given including tris- [4,4,4 - trifluoro - 1 - (2 - thienyl) - 1,3 - butanediono]-Eu in dimethylformamide; [C 6 H 5 COCH: C(CH 3 )O] 3 Tb in dichloroethane. Quenching occurs due to electron injection and ceases when the current is removed or the polarity reversed. Recovery after the current ceases can be delayed using viscous materials, e.g. silicone oil, sucrose or cholesteryl oleyl carbonate. In these cases recovery is speeded by reversing the polarity. A non-quenching fluorescent dye may be added to obtain a multicoloured effect, e.g. mono-bromofluorescein Na salt, Eosine. Information is displayed on a panel comprising the material placed between crossed conductor arrays or between a figure of eight array and a continuous conductor and illuminated by an U.V. lamp. To increase contrast only the figure of eight may be illuminated by using an apertured U.V. filter. Images may also be projected on to the panel.
