- Editor's Notes
- Dyer-- Patent-- It is not practicaly to work motors on alternaing circuit--s currents of the same direction are essential. This invention consists in a method of causing alternating currents to be all in one direction in various circuits which are to contain motors. I accoplish this by using a large number of cells containing in each cell a large number of very thin lead places [plates?] close together immersed in Sulphuric acid & water-- Enough cells are employed so the Counter EMF is only slightly less than the prime EMF-- Hence one alternation is almost balanced by the battery & only a weak current passes while the opposite alernation is added to the battery which doubles the EMF-- The motor being wound to work with this EMF The Lamps may be in a second circuit or the same circuit The volts will be 2.5 and no depreciation or weakening of solution takes place-- the internal resistance is remarkably low-- lower than it is possible with a storage battery= the converting power per pound of lead is enormous
