provement in the upper copper clamp, J, connectingthe heater with one of the copper tubes carrying the electric cur-rent and the cooling water, may be worthy of mention. As origi-nally constructed, only one-half of this clamp was water-cooleddirectly, the other half being connected to it only by… … Fig. 2 of heat along the side pieces L,h, which fit closely upon the water-cooled half M. The temperatures were measured by means of a Morse opticalpyrometer of the Holbom-Kurlbavim type,^ which was sightedvertically downward through the furnace window.
