Abstract

533,868. Correspondence control. KOLLSMAN, P. Dec. 7, 1939, No. 31661. [Class 40 (i)] [Also in Group XXXVI] A device for indicating the speed relations of aircraft engines comprises a pair of 3-phase generators I, II driven by the engines driving tachometers 7, 8 and a synchroscope comprising a Z-shaped armature excited by one phase of generator I and rotatable in the field of a pair of coils at right angles and fed respectively by two phases of the other generator II.
