Abstract

268,747. British Thomson-Houston Co., Ltd., (Assignees of Wright, D. K.). March 31, 1926, [Convention date]. Transformers. - In a machine for securing bases to electric lamps &c., the bases are heated to set the cement contained in them by electric current applied directly, a number of lamps being mounted around a turret so that each base is engaged by a pair of contacts, each pair of which is connected directly to a corresponding secondary winding 27, and all the windings 27 are associated with a single primary winding 28.
