- Editor's Notes
- "The experiment with two different plates is very conclusive. I find that there is comparatively a small difference between the iron and bronze sleeves, and there is only a small difference between both of these and the regular method of making the armature. I also find that in the test you made of the new Edison solution it did not show any perceptible increase of heat over the regular paper. What I should like therefore to be done immediately is to put some one on to the painting machine to find out the reason why, in painting these plates, the paint should be put on thicker nearer the centre than the circumference. And also to try if it cannot be avoided by making the liquid thinner or running at different speeds or by some other method. I think an armature should be built up on those thin plates painted. They should be put on an iron or bronze sleeve and it should be jappaned and then the plates all screwed together from the end, similar to what we are doing on the converter. Will you not appoint somebody immediatley to take this inhand so as to get a result as quickly as possible?. I think it would be well to make the No. 16 armature with the this plates right up into a regular armature and then see what is the difference in heat with its regular full load test."
