Abstract

738,914. Transformers. GENERAL ELECTRIC CO., Ltd., and SHAW, H. J. H. July 28 1954 [Aug. 4, 1953], No. 21484/53. Class 38 (2)' A loud-speaker coupling transformer 1 is provided with a plurality of tappings 2 ... 7 on its secondary winding, the tapping being so arranged that the impedance reflected into the primary circuit will be approximately the same when either one, two or three similar loud-speakers are connected between specified pairs of tappings. The ratios of the numbers of turns between pairs of tappings and the total number of turns between the tappings 2 and 7 are
