Abstract
657,292. Transformers. MARTIN, M. T. Aug. 30, 1946, No. 26215. Convention date, July 19, 1945. Addition to 643,846, [Group XXXVIII]. [Class 38 (ii)] [Also in Groups XXXVIII and XL (c)] A tuned transformer for use in the electronic organ described in the parent Specification has an open or air-gapped magnetic core A, a winding I3 for eliminating. cross-modulation wound on and tightly coupled with a primary winding I2 and a secondary winding I1 less tightly coupled with the primary. The transformer core may be bar shaped as in Fig. 1, or of double E-shape as in Fig. 5. The secondary may be wound in two portions I1, I11 as in Fig. 3. Transformers T1, T2, Fig. 6, forming part of a chain are mounted with an output valve L as a unit. The unit also includes the resistance reactance and switching components of the transformer circuit.
