Abstract
829,395. Making pre-focus electric lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 7, 1958 [March 12, 1957], No. 7427/58. Class 39(2) In a method of manufacturing pre-focus electric incandescent lamps of the type having a stepped aligning flange secured to the larmp cap for supporting the lamp in reflectors having openings of different sizes for receiving the flange so that the incandescent body of the lamp is always located at the focus of the reflector, the securing means for the flange is provided at approximately the level of the cement on the cap and the securing of the parts is effected by simultaneous heating of the parts. The lamp shown has a cap 9 arranged on the neck of the bulb 1, a thermo-hardening cement 10 being applied at the junction. The flange 12 is placed over the cap at the level of the cement, the flange having a conical inner edge in which a ring 17 of solder is placed. The combination is heated by means of a refractory ring 18 itself heated by gas burners.
