An improved telephone ringing circuit in which a non-polarised high voltage electrolytic condenser using an electrolyte containing a solute of high molecular weight is used to separate out the alternating ringing current. Following assembly, the condenser is connected to a periodically reversed volt...

Summary:An improved telephone ringing circuit in which a non-polarised high voltage electrolytic condenser using an electrolyte containing a solute of high molecular weight is used to separate out the alternating ringing current. Following assembly, the condenser is connected to a periodically reversed voltage, to improve the dielectric oxide layer on the aluminium electrodes.
