ermore, at this temperature the radiator is easily held con-stant to o.°i, which is necessary in view of the fact that undercertain conditions a change in temperature of o.°i was perceptiblewith the receiver. This radiator was painted with a mixture ofcobalt and chromium oxides. A series of… … HORIZOMT4L SzcrroNFig. 5.—Assembled apparatus. tube.
