Abstract

907,053. Coating lamp bulbs internally. GENERAL ELECTRIC CO. Ltd. Feb. 28, 1961 [March 4, 1960], No. 7769/60. Class 39 (2). [Also in Group II] Apparatus for coating part of the internal surface of a bulb by a vacuum evaporation process includes a shield consisting of one or more flexible resilient leaves mounted so as to be capable of expanding against the internal surface of the bulb under the influence of an external magnetic field, the edges of the leaf or leaves being overlapped so as to form an uninterrupted screen. In the form shown, the coating material which may be aluminium or a copper-aluminium alloy in the form of a short rod 18 is supported within a heating planet 3 carried by terminal blocks 5, 8 mounted on a rod 4 and sleeve 6 respectively by which current is conveyed to the planet. A collar 12 surrounding the sleeve 6 supports four spring strips 13 each carrying at its upper end a mild steel strip 14 to which is welded a sheet 15 of molybdenum foil, the lateral edges of the sheets being overlapped. The assemblage is inserted in the bulb 2 to be coated and the whole mounted in a vacuum chuck 11 and evacuated. A frame carrying four permanent magnets 16 is then lowered over the bulb 2, with a magnet opposite strip 14 so that the leaves 15 are drawn into contact with the interior of the bulb. An oven 19 is then lowered over the part of the bulb to be coated, a screening plate 20 being interposed between this and the magnets and current is then passed through the planet 3 to cause evaporation of the metal rod 18. A shield 17 is provided to protect the blocks 5, 8 from the deposition of evaporated metal.
