Abstract: While a transmitting transducer (2a) for transmitting an ultrasonic wave and a receiving transducer (2b) for receiving an ultrasonic wave are moved within a predetermined circular region (7) on a surface of a material being measured, ultrasonic waves are transmitted and received 10,000 times. Then, arithmetic averaging is performed every time an ultrasonic wave is received, on the ultrasonic wave and ultrasonic waves that have been received until then. For example, the aforementioned predetermined frequency is given by ((n±(½))×(106×v/&Dgr;L))(Hz), where &Dgr;L is a variation in distance between the transmitting transducer and the receiving transducer, v is a transmission velocity of an ultrasonic wave transmitting in a material being detected, and n is a natural number.

Abstract: An acoustic nonlinearity parameter (&bgr;) measurement method and system for Non-Destructive Evaluation (NDE) of materials and structural members novelly employs a loosely mounted dielectric electrostatic ultrasonic transducer (DEUT) to receive and convert ultrasonic energy into an electrical signal which can be analyzed to determine the &bgr; of the test material. The dielectric material is ferroelectric with a high dielectric constant ∈. A computer-controlled measurement system coupled to the DEUT contains an excitation signal generator section and a measurement and analysis section. As a result, the DEUT measures the absolute particle displacement amplitudes in test material, leading to derivation of the nonlinearity parameter (&bgr;) without the costly, low field reliability methods of the prior art.

Abstract: A method of characterizing the vibration of a plurality of rotating blades (12), such as turbine blades in a gas turbine engine, includes the steps of providing a single strain gauge (16A) on a single one (12A) of the blades and providing either one or two tip timing probes (22A, 22B) on a casing surrounding the blades. The data from the strain gauge (16A) allows the vibration of the single blade (12A) to be fully characterized while the data from the tip timing probes (22A, 22B) allows the amplitudes or velocities of vibration of all the blades to be determined. The relationship between the data from the tip timing probes for the single blade (12A) and the stress data from the strain gauge may be established. This relationship may then be assumed to apply to all the blades, thus allowing the stresses induced in all the blades by the vibrations to be determined.

Abstract: An assembly for measuring fluid flow is provided having a base plate with an upstanding wall and a cut-out opening. A pivot shaft extends from the wall and a swinging arm is attached to the pivot shaft. At the lower end of the arm is a barrel shaft which supports a rotatable barrel.

Alternatively, the assembly may be located above a top opening in a pipe containing a flowing stream of fluid. In this case, the arm and barrel will swing down through both the base plate cut-out opening and the pipe top opening. The moving fluid causes rotation of the barrel which is detected by a barrel rotation sensor. The sensor sends electronic signals to a signal processor which produces fluid velocity data. The arm may have an angular position sensor which will also deliver electronic signals to the signal processor.

Abstract: A gear for use as the pinion in a rack and pinion gear includes spur gear teeth that have an upper portion of the face cut in a worm cut so the gear is effective as a worm wheel for a worm gear while retaining involute curved faces so it is effective as the pinion for the rack.
