Abstract: Applicant's Differential-Pressure Torque Measurement System generates the torque signal from a differential gas pressure measured across the power turbine. The gas pressure differential is measured by using two pressure taps, the first tap taking the pressure reading of the expanding gas as the gas travels from the gas-generating turbine to the power turbine of the engine and the second tap taking the pressure reading of the gas as it escapes the engine through the exhaust port. The differential between the two pressure readings is determined. The pressure differential is then input to a processor which processes it in a pre-determined fashion along with the rotational speed signal of the power turbine, initial pressure and the temperature measurements of the air as the air is initially inlet into the engine. The result of the processing are various engine parameter indications including the torque.

In an unbiased state, the magnetization vector of each of the ferromagnetic layers is preferably parallel to each other.

Upon application of stress, the magnetization vectors of both free magnetic layers will rotate, thus causing a corresponding and proportionally related change in the resistance of the sensor. This change in resistance can be sensed and used to calculate the stress applied thereto.

Abstract: A thread wear gauge for coil threads. Coil threads have a nominal new thread profile that offers a substantial load bearing area. The thread wear gauge has a gauging thread with a silhouette that permits it to threadably engage with a coil thread that has been worn so that the shear load bearing area of the thread has been worn away from the coil thread to the point where the coil thread is unsafe for further use. The gauging thread will not threadably engage with the coil thread if the load bearing area has been worn to the point where it is unsafe. The thread wear gauge is a simple, reliable, hand held tool that is capable of being used under field conditions. In use, the thread wear gauge is grasped and manipulated with one hand. An attempt is made to threadably engage the gauging thread on the thread wear gauge with the coil thread that is to be tested. The operator observes whether the gauging thread threadably engages with the coil thread. If it does engage, use of the coil thread is discontinued.
