Abstract

907,011. Capacitance networks. GENERAL ELECTRIC CO. Ltd., and PHILLIPS, F. C. F. Dec. 7, 1960 [Dec. 7, 1959], No. 41489/59. Class 40 (8). [Also in Group XXXVI] A decade capacitor of the 1, 2, 2, 5 type has the unit capacitor 3a connected to a highpotential line 47 by the alternate steps of a switch 1, 3, 5, the corresponding studs of the switch, 6, 8, 10, being screened by the interspersed studs 5a, 7, 9 and the wiring thereto being earthed. Further screening may be provided by a member 50 arranged to isolate the contactors of the moving switch member 44.
