Magnetic amplifier sequential circuits of the asymmetrical type

THE intent of this paper is to disclose as briefly as possible some new ways of interconnecting magnetic amplifier flip-flops in the hope that these can be adapted for useful purposes. These circuit arrangements may be considered as analogues of manually or mechanically actuated contact-making devices. The basic switch function is an operation in one sense for on and an action in the opposite sense for off as in the common toggle switch. Another familiar type of switch, not quite so frequently encountered, is called the ¿canopy¿ or ¿chain-pull.¿ When this is operated successively, in one sense only, it gives alternately on and off action. Relays that do this are well known and are sometimes called impulse relays. When relays of this type are repeatedly energized, they will alternately open and close their contacts. Devices capable of this kind of response form the basis of binary systems applicable in the digital computer field.
