Abstract

1,099,746. Moulding lamp fittings. WESTINGHOUSE ELECTRIC CORPORATION. June 30, 1966 [July 19, 1965; June 1, 1966], No. 29408/66. Heading B5A. [Also in Division H1] An electric discharge or incandescent lamp has a vitreous envelope from an end portion of which a conductor or conductors 9, 10 extend and a body of plastics material having a cellular structure, bonded directly to the envelope and holding the conductors. In making a discharge lamp 5, the end is inserted in a mould 16 of resilient material, such as silicone rubber, which may be reinforced by an outer metal casing 18. Hollow contact pins 14 are supported in recesses 20 in the mould and the lead-in wires 9, 10 passed through these. The mould is then filled with plastics resin incorporating a foaming agent and heated in a furnace 24 until the resin foams and fills the cavity 17 of the mould, the foamed resin being then cured. Suitable plastics are polyurethane, polystyrene, epoxy, silicone and cellulose acetate foams. The mould may alternatively be filled by the thermosetting plastic and a foaming agent e.g. benzene sulphonyl hydrazide subsequently introduced through a tube 26 in the base of the mould.
