摘要: The invention relates to an overpressure protector comprising a body portion (1) of single crystal silicon, a burst flow conduit (2) extending through the body portion (1), and a membrane (3) covering the burst flow conduit (2) and responding to a pressure difference. The membrane is a thin film (3), which is arranged to break when the pressure difference acting across it exceeds a predetermined value, and comprises a belt (6) whose electrical conductivity differs from that of the other material of the membrane. The belt is connected to means (9) for supplying electric current either for detecting breaking or the belt or for bursting the membrane (3) intentionally by means of heating effect of electric current.

摘要: Reflector for electric lamps. The reflector comprises a part of aluminum plate of the shape of a truncate ball segment, and in connection with it a part of the shape of a paraboloid, and which is provided with one or several elastic fixing means for fixing the reflector detachably to the lamp-globe. One or several naillike projections are pressed into the reflector, through which one end of a spring serving as fixing means is brought, while the other end protrudes from the inside surface of the reflector, so as to press against the lamp-globe.
