Abstract
822,660. Magnetic amplifiers. SPERRY RAND CORPORATION. May 17, 1957, No. 15710/57. Class 40 (9). A group of cores 00-11 having rectangular hysteresis characteristics are magnetized from a source PP-1 of alternating pulses, the positive pulses being applied to bias windings 24-26 on all but one of the cores and also by way of switches 12, 13 to none, one or the other, or both of two input circuits comprising winding groups 16-19 and 20-23, while the negative pulses are applied to restoring windings 37-40 which drive all the cores to saturation in the same sense. Each core also has an output winding 27-30 which is connected to an individual output terminal 31-34, the output circuits each including a biased rectifier 35, 36 which limits the rate of change of flux when cores are changed from one saturated state to the other. Rectifiers 41 in the input circuits are also biased by a negative potential 14. In operation, with both switches open, all the cores except core 00 have their initial saturated state as established by the restoring windings reversed by positive pulses in the bias windings, and outputs are induced in the respective output windings 28-30. Again, with switch 13 closed, the fluxes in core 01 alone are ineffective so that only this core remains in its initial saturated state and produces no output. Similarly, cores 10 and 11 remain in the initial state when switch 12 or switches 12 and 13 are respectively closed. In a modification, Fig. 3, each output winding 45 and its load 44 is connected by way of rectifier 46 to an alternating pulse source PP-2 which has an antiphase relationship to PP-1. The positive half cycles of PP-2 magnetize the cores in the same sense and time position as the PP-1 pulses in the restoring windings 37-40, so that only that core which is left in its initial remanent state by the input circuits permits current to flow to a load. It is stated that this arrangement provides amplification and enables the restoring windings to be omitted.
