11,081. Elektrizitõts Akt.-Ges. vorm. W. Lahmeyer & Co. May 12, [date applied for under Patents Act, 1901]. Void. [Published under Patents Act, 1901.] Dynamos, regulating; field magnets ; sparking, preventing.-Relates to the method of compounding direct-current generators described in Specification No. 8786, A.D. 1906, in which an additional set of brushes on the commutator is short-circuited on itself or through adjustable resistances, and consists in substituting for the short-circuit a field winding, the axis of which coincides with that of the main field winding or forms any desired angle therewith. Adjustable resistances may be placed in the circuit of the auxiliary field winding. To prevent sparking at the brushes, the field core may be formed with twice as many polar projections as there are poles.
