824,047. Electromagnetic couplings. COHEN, E., and ROTH, S. June 4, 1957 [June 29, 1956], No. 17684/57. Class 35. A powder coupling has a wound stator surrounding an outer and an inner rotor at least one of the rotors having notches facing the other rotor member. As shown, the inner rotor has teeth 4 and the powder may be a mixture of iron carbonyl and talc. Fan 16 on shaft 7 dissipates the heat generated. Specification 790,080 is referred to. Reference has been directed by the Comptroller to Specification 764,811.
