Abstract
217,984. British Insulated & Helsby Cables, Ltd., Bullock, S. C., and Wilson, L. H. March 26, 1923. Switching systems for transformers; regulation, automatic; switching systems for heating appliances.-When the resistance across the work 8 in welding is reduced, the current from the secondary through a solenoid 20 ceases to balance that in a. solenoid 17 energized from the primary side of the supply transformer and a switch is actuated to cause the energization of a main solenoid 10 and the cutting off of the supply.
