8786. Elektrizitõts Akt. - Ges. vorm. W. Lahmeyer & Co. April 28, 1905, [date applied for under Patents Act, 1901]. Dynamos, regulating; sparking, preventing.-In the method of obtaining constant potential from direct-current generators described in Specification No. 8526, A.D. 1906, in which the commutator is provided with an additional set of brushes connected to a source of practically constant potential such as an accumulator, the source of constant potential is dispensed with, and the auxiliary brushes are short-circuited or connected together through adjustable resistances. In order to prevent the current in the short-circuited brushes from becoming too heavy, the magnetic resistance of the main armature field is made large, or the main armature field is neutralized by means of a compensating-winding arranged on the stator and traversed by the main armature current.
