Abstract

561,796. Supply meters. MEASUREMENT, Ltd., BATT, F. H., and CLIFFORD, C. F. Feb. 25, 1943, No. 3123. [Class 37] The rotor disc a of an induction type meter or instrument is made of copper, is of thickness not less than 40 per cent (preferably about 50 per cent) of the total gap g between the driving elements b, c, and is in part suspended or supported magnetically so as to reduce wear on the bottom bearing d. The magnetic suspension means are described in Specification 561,795.
