Abstract
551,709. Transformers. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 19, 1941, No. 12142. Convention date, Sept. 20, 1940. [Class 38 (ii)] A variable reactance transformer for supplying welding loads, for example, comprises relatively movable primary and secondary windings 11, 12 and a pair of series-connected auxiliary windings 32, 33 closely coupled respectively to the primary and secondary windings and adapted to be connected in series with either the primary or secondary winding to extend the range of reactance variation. The structural arrangement may be as described in, Specification 444,301.
