Abstract

897,569. Operating single-indication receivers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 18, 1959 [Feb. 18, 1958], No. 5633/59. Drawings to Specification. Class 118. [Also in Group XL (c)] Change of state of a magnetic core causes a transistor blocking oscillator (see Group XL (c)) to commence generating pulses, which operate a lamp or relay connected in the collector circuit of the transistor, thus giving a long term indication that the change of state has occurred.
