Title: Safety circuits for coupling laddics in cascade

Abstract: A coupling arrangement for coupling laddics in cascade comprises an emitter follower transistor circuit arranged so that the output impedance of the transistor restricts the rise and fall times in the mmf of the laddic output winding. The effect is to reduce the risk of spurious reset signals being generated in the output winding of sufficient amplitude to reset the next laddic in the cascade.
