Abstract: ABSTRACT OF THE DISCLOSURE                  In a metal halide lamp of the sodium-scandium-thorium iodide type utilizing tungsten electrodes without emission mix, lumen depreciation during life results primarily from blacken-ing of the arc tube wall by electrode sputtering during the glow-to-arc transition phase of lamp start-up.  The glow-to-arc transition is speeded up by a lower glow-to-arc transition voltage which is achieved by using electrodes comprising an open tungsten wire coil on a tungsten shank, the coil comprising two layers of a composite wire made by open-winding a 2 mil overwind on a 4 mil core and then close-winding two layers of the composite wire on the shank.  This decreases sputtering at at starting and improves lamp maintenance.

Abstract: ABSTRACT         To minimise the stresses arising in a nuclear-reactor calandria due to differential axial expansion of the through-tubes consequent on unequal irradiation growth, while yet preserving the structural strength advantage of securing the through-tube ends rigidly to the end plates, the through-tubes are formed with axially alternating regions of greater and lesser wall thickness.   The thicker regions provide the required tube stiffness  and resistance to internal and/or external fluid pressure, the thinner regions accommodate differential axial growth by providing the necessary axial strain under a reduced axial stress (end load).  The different wall thicknesses can be produced by machining (leaving integral thickenings) or by fabrication (provision of separate strengthening rings);  and a variant (in either case) is an integral or separately applied continuous spiral thinkening.           In e.g., tube boilers, the invention copes in similar manner with differential thermal expansions.
