24,792. Hamilton, W., and Ferranti, Ltd. Dec. 30. Induction motor meters.-A piece g of unlaminated iron is pivoted on an iron stud h on the central limb of the core of the pressure coil and is adjustable in a tangential plane to compensate for friction. A copper ring p may be added tu increase the effect. A slotted brass plate serves to hold the piece after adjustment.
