Abstract

This high speed branching circuit uses a two phase clock drive and a transfer circuit with a series capacitor C. With core S(1) in a 1 remanence state, an A drive pulse resets it to 0 causing a counter clockwise current flow which charges C(1) and switches core K(2) from 0 to 1. In switching to 1, K(2) causes a clockwise current flow in each branch circuit charging capacitors C(2a), C(2b) and C(2c). When the rate of switching of K(2) decreases, C(1) discharges providing a counter clockwise current flow in loop 1 tending to reset K(2). Simultaneously, cores C(2a), C(2b) and C(2c) discharge causing counter-clockwise current flow in the branch loops tending to switch cores S(2a), S(2b) and S(2c) to the 1 state.

Capacitor Branching Circuit

This high speed branching circuit uses a two phase clock drive and a transfer circuit with a series capacitor C. With core S(1) in a 1 remanence state, an A drive pulse resets it to 0 causing a counter clockwise current flow which charges C(1) and switches core K(2) from 0 to 1. In switching to 1, K(2) causes a clockwise current flow in each branch circuit charging capacitors C(2a), C(2b) and C(2c). When the rate of switching of K(2) decreases, C(1) discharges providing a counter clockwise current flow in loop 1 tending to reset K(2). Simultaneously, cores C(2a), C(2b) and C(2c) discharge causing counter- clockwise current flow in the branch loops tending to switch cores S(2a), S(2b) and S(2c) to the 1 state.

The combined current due to discharging the branch circuit capacitor is less than that of capacitor C(1) as an energy loss was involved when K(2) was switched initially. K(2) is reset to 0 and S(2a), S(2b) and C(2c) are switched to 1. Energization of the B drive shifts the information out of the several branch loops.
