Abstract
1,226,869. Glass-melting furnaces; coating with glass. TOYKYO SHIBAURA ELECTRIC CO. Ltd. 4 Sept., 1968 [4 Sept., 1967; 10 Jan., 1968; 5 July, 1968], No. 41985/68. Heading C1M. [Also in Divisions F4 and H5] An electrically-heated glass-melting furnace, for coating with glass in the sealing of glass, metals or ceramics to each other, comprises a bath to accommodate the molten glass 16 therein, a pair of mutually facing electrodes 14, 15 disposed inside of said bath to pass an electric current at the surface region of the glass, said electrodes having their opposed faces inclined in such a manner that the distance between them is smallest at the top of the bath and increases gradually towards the bottom, cooling means 20 provided at said bath bottom to cool the lower part of the charged glass material and a powersupplying means 21 connected-across-said electrodes. As shown, the angle between the said electrodes 14, 15 is suitably selected within the range of from 120 to 160 degrees according to the inter-electrode space and the composition of the molten glass. Workpieces to be sealed together or coated with the glass are dipped into the molten glass, the glass material 16 being melted by impressing an A.C. voltage across the electrodes; the depth of the material 16 being cooled by the action of water running through the pipes 20 causing the electric current to concentrate on the surface area of the material 16 in the bath. Also described in the Specification is a constant current control device between the electrodes and the power supply means.
