Abstract: METHOD AND APPARATUS FOR MAKING         MOLTEN GLASS                        Ronald L. Schwenninger Abstract of the Disclosure In a continuous, fuel-fired, glass melting furnace, a pair of substantially horizontal, longitudinally extending electrodes are provided in the molten glass closely adjacent to the sides of the floating hatch blanket for supplying electrically generated booster heat to the underside of the batch blanket.  The electrodes extend a substantial distance into the melting zone of the furnace through the fill end wall.  The electrodes also serve as physical barriers that prevent the batch blanket from drifting into contact with sidewalls of the furnace.  The electrode arrangement boosts melting rates with efficient utilization of electrical energy, and avoids furnace wall erosion and unbalanced melting conditions.

When the booster tube's beam is excited, the signal is amplified about 10dB.  Upper bandedge instabilities in the lossless tube are inhibited by a lower cutoff frequency of the circuit near the output end than near the input end, so that the bandedge power can flow both ways out of the large-signal output end.
