161	Selectively operable rotary drive means	US643689	1984-08-23	US4540381A	1985-09-10	Edward W. Molloy; Ronald E. Shafer
An alternator cooling fan drive includes a radial bearing, the outer race of which mounts the fan within the magnetic field produced by the alternator under load. The bearing has pathways with a curvature close enough to the balls that the races will self-center and transmit a minimum torque to the fan when the magnetic field is weak. The pathway and ball configurations are sufficiently divergent that when the magnetic field pulls in on the fan, the races can misalign and wedge the balls more tightly between the races to transmit more torque to the fan. The fan drive is thus more directly responsive to the need for cooling.

Apparatus for utilizing heat wasted from an engine includes first pressure detecting means (73) and first temperature detecting means (81) for detecting a pressure and a temperature in a refrigerant passage extending from a condenser (38) to a refrigerant pump (32), second pressure detecting means (72) and second temperature detecting means (82) for detecting a pressure and a temperature in a refrigerant passage extending from a heat exchanger (36) to an expansion device (37), and control means (71) responsive to these four detecting means when operating a Rankine cycle (31). Means (71) is for diagnosing whether or not an electromagnetic clutch (35) is stuck responsive to either the first pressure detecting means (73) and the first temperature detecting means (81), or the second pressure detecting means (72) and the second temperature detecting means (82).
