Abstract

483,194. Master control of D.C. motors ; electric systems for controlling lifts ; dynamos. WAYGOOD-OTIS, Ltd. Nov. 18, 1936, No. 15298/37. Convention date, June 15, 1936. Divided out of 483,163. Drawings to Specification. [Class 38 (iii)] [Also in Group XXXV] Varying E.M.F.-The subject-matter described is the same as that described in Specification 483,163, but the claims relate to the provision of a separately excited field winding on the generator for establishing its polarity, and a shunt field winding connected across the generator armature to build up its voltage when the polarity has been definitely established by the separately excited winding. Specification 297,801, [Class 78 (ii)], also is referred to.
