The system is unitized eliminating custom design of simple systems.

Abstract: A dynamo-electric machine is provided with a protective circuit arrangement whereby the machine is caused to be switched off if a short circuit current flowing in the machine exceeds a predetermined level.False operation of the protective circuit is avoided by incorporating a discriminating circuit which is able to distinguish the phase angle between the current and the voltage. This causes the protective circuit to trip for an over load current where the phase angle difference is small and the power factor near unity, which occurs with resistive fault situations; and not to trip where the phase angle difference is high, and thus there is a low power factor indicating a reactive condition, which occurs on start-up of the machine. A machine is able to run more safely as a result.

Abstract: A helicopter rotor is formed with spars and ribs. The spars form parts of the surfaces, and long slots are constructed in the spars to provide suction and blower slots. Air is withdrawn in slots nearest the leading edge, and engine exhaust is conducted to a suction/blowing device which in turn blows air through slots near the trailing edge. Helicopter engine exhaust is mixed with air and fuel and is recombusted. Air is drawn into a recombustion chamber of a suction/blowing device from suction surfaces on the helicopter rotor blades. This suctioned air is then re-routed to the slots near the trailing edge and blown over the upper and lower surfaces of the blade.

Abstract: Two sensors spaced at a known separation produce signal pulses when activated by the wheels of a taxiing aircraft. The signals are transmitted to a processor in which the wheelbase of the aircraft can readily be calculated. Since specific aircraft types have unique wheelbase dimensions and characteristics, the type of aircraft passing the sensors is determined in a processor. Also, the time, direction, and speed of the aircraft can be determined and logged by the processor.
