Page 17 - At or near every point where it is required that a light shall be produced, we arrange a coil (or series of coils) of insulated metallic wire or ribbon (preferably surrounding a bar or wires of soft iron), through which coil or coils the current from the principal wire first described can be passed when desired, or cut off by means of a key or lever. Bound or adjacent to each coil of insulated wire described, we form one or more secondary coils of insulated metallic wire or ribbon, arranged so that...
Page 39 - Schlusse gesagt: * system of distribution, but what about the size of conductors for such a system ? Prodigious. Unter „secondary generator" ist hier ersichtlich das System der beiden auf einander inducirend wirkenden Spiralen gemeint.
Page 8 - Grove element in inducing in the secondary circuit such a high electromotive force as produced sparks 4J inches in length through a vacuum tube — a result that Kuhmkorff, although his invention created such a great and well-deserved attention, did not attain.
