Abstract: A high-pressure discharge lamp includes a ceramic discharge vessel which encloses a discharge space containing two electrodes and an ionizable filling including a metal halide. The discharge vessel includes a central cylindrical part with an end, and an end part closing the cylindrical part at the end in a gastight manner. The discharge vessel also has a projecting plug connected to the end part in a gastight manner for enclosing a feedthrough conductor. The end part is monolithic and its outside surface includes an angle A with the longitudinal axis of the discharge vessel at the projecting plug, where the angle A is between 30 and 60 degrees. The outside surface of the end part may be shaped like a truncated cone with a base extending radially outward. Alternatively, the end part includes two concentric tubular portions which are interconnected in a gastight manner.

Abstract: A device, and method of using such a device, for measuring tension in a thin flexible tape by guiding the tape along a curved path between two parallel curved guides, supplying pressurized gaseous medium to each side of the tape, and measuring the difference in gas pressure between the two sides of the tape. Measuring ducts, terminating substantially opposite each other in the curved guide surfaces are connected to at least one pressure transducer which in turn is connected to an electrical measuring circuit.
