Abstract

998,808. Circuits employing bi-stable magnetic elements. HOLLANDSE SIGNAALAPPARATEN N.V. April 27, 1962 [May 10, 1961], No. 16227/62. Drawings to Specification. Heading H3B. [Also in Division G4] A magnetic storage matrix is adapted to produce fixed outputs by coating cores which are not required to produce an output pulse with a conductive coating, preferably of conductive paint. The coating provides a low resistance circuit which lengthens the switching time and hence reduces the output voltage. A prior art method in which mercury is allowed to enter cores which are not to produce an output is also described.
