In order to obtain a non-inductive resistance, a pencil mark on paper was tried; but to convey any appreciable current a very heavy mark was required, the graphite then was rapidly dispersed on sending a current. Marks made with lead and aluminum on sand-paper were similarly ineffective. Remy 6 volt 12 cyl. coils were used Signed (Cont'd) This Sheet must be filed on completion of the work. | ||
