TEMPERATURE PULSE CONTROL DEVICE FOR MULTI-ZONE RESISTANCE FURNACE Russian patent published in 2014 - IPC G05D23/00 F27D19/00 

FIELD: electricity.

SUBSTANCE: device comprises n voltage regulators coupled by their first power leads to outputs for connection to the network and by their second power leads to outputs for connection of n loads, synchronizing pulse generator which input is coupled to outputs for connection to the network while outputs are coupled to pulse distributing input, as well as n control pulse generators based on reverse binary counter, the above generators have pulse information inputs coupled to outputs of the pulse distributor, pulse synchronizing inputs, control inputs, control outputs coupled through the logic circuit to the pulse synchronizing inputs, at that a conjunctor is used as the logic circuit and pulse information control inputs coupled to control inputs of the voltage regulators are introduced in the control pulse generators.

EFFECT: reducing temperature variations in electric furnace control zones.
