  • Method of manufacturing an electrode provided with connection
    Patent number: 3979628
    Abstract: A method of manufacturing an electrode provided with a connection conductor for a gas and/or vapor discharge lamp. A quantity of electrically conducting auxiliary material, having a melting point less than the turns, is introduced between several turns of the electrode. Subsequently this assembly is heated to above the melting point of the auxiliary material below the melting point of the material of the turns. Cooling takes place after auxiliary material has flowed between the turns. Subsequently the auxiliary material is connected to the actual connection conductor which may be a bushing shaped lead-through conductor.
