Abstract: The invention relates to a method of manufacturing a gas-filled electric incandescent lamp particularly a low-voltage incandescent lamp in which the wire diameter of the incandescent civil varies in different axial sections. The diameter of the tungsten wire is reduced at the end turns and is increased in the middle with the aid of a chemical cycle process either before or after mounting in the lamp in order to reduce the temperature differences between the turns in the middle and at the end of the coil during operation of the lamp at the prescribed operating voltage.

Abstract: The invention relates to a device for igniting flash-bulbs which is adapted to be coupled to a photographic camera and includes a freely movable member which when the shutter mechanism of the camera is operated is accelerated by the action of a pin which is connected to this mechanism and springs out of the camera wall to strike a piezo-electric element to which the flash-bulbs are electrically connected.
