Abstract
517,606. Protective arrangements; transformers. GENERAL ELECTRIC CO., Ltd., and JACOBY, H. C. E. Aug. 11, 1938, No. 23706. [Classes 38 (ii) and 38 (iv)] Radio-interference arising from electrical appliances such as vacuum' cleaners is suppressed by including, in each supply lead, highfrequency chokes magnetically coupled together, the degree of coupling being variable to suit the requirements of each local situation. In the arrangement shown in Fig. 1, the relatively-moving chokes 9, 10 on the common core 11 are included in the supply 'leads to the series motor 4 having a two-part field winding 2, 3 and condensers 6, 7, 8 located as shown. The common core may be' centrally notched to afford further range of coupling or a two-part core, each part movable, may be used in association with fixed windings. In the arrangement shown in Fig. 5A the windings 12, 13 are on the cross laminations 19 bridging the, arms of a closed magnetic circuit. Further laminations are arranged at right angles to and threaded between the laminations of 19 and by varying the proportions between the two types of laminations the degree of coupling between the coils can be varied.
