Abstract

17,222. Olivetti, C., and Gatta, D., [trading as Olivetti & Co., C.]. Aug. 25, 1904, [date applied for under Patents Act, 1901]. Transforms.-The core of a transformer for use with measuring - instruments, switches, &e. is made of solid or partiallylaminated magnetic material, and is in the form of a closed box provided with a central leg for the coils. As shown in Fig. 2, the core consists of a box 1 and a cover 2, both of magnetic material, from which projects the solid leg 3 on which the primary coil 5 and secondary coil 6 are wound, their ends being connected to two pairs of terminals 7, 8. A small air gap may be left between the leg 3 and box 1. The core may be slotted in order to reduce the effect of eddy currents on the phase-difference between the primary and secondary currents. Slots 9 are shown in Figs. 3 and 4.
