NEW DESIGNS IN FRACTIONAL H.P. MOTORS

Great interest has already been aroused in the re- cently announced range of fractional-horas- power motors made by Hoover, Ltd., at their modern factory at Cambuslang in Scotland. The design is new, embodying the experience gain- ed in the application of electric motors to re- frigeration, washing machines, and many domestic appliances, as well as for powering engineering, textile, dairy, printing, and many other industries, and incorporating the latest information secured by research.
