Abstract:
This invention refers to a sonic and/or ultrasonic generator for emission in air with a power capacity and certain radiation characteristics which permit the necessary acoustic levels (>170 dB ref. 2.10−4 μbar) to be obtained in a way that is safe and controlled for the mechanical breakage of high consistency bubbles constituting industrial foams.
Abstract:
The invention relates to a method and device for determining the fatigue resistance of metallic materials at ultrasonic frequencies and a constant temperature. The inventive method can be used to examine materials subjected to bending and traction/compression stresses at different temperatures ranging from atmospheric temperature to 1000° C. and at high frequency. Said method can be used to evaluate the breaking stress and the number of cycles to which the material has been subjected and to record the break profile. The device comprises an excitation system, a data acquisition system and resonant samples of the material.
Abstract:
A marine hydraulic system and method of use for reducing cyclic loading of the pump(s) and motor(s) and an amount of accumulator storage required in a hydraulic system. A closed loop logic controller comprising at least one control algorithm for each pump/motor pair utilized in a single hydraulic system is utilized to reduce load fluctuations on the motors, allow the use of common pressure compensated, variable displacement (VDH) pumps, reduce the number and/or volume of system accumulators and equalize wear throughout the system.

Abstract:
Technologies relating to a magnetic resonance spectrometer are disclosed. The magnetic resonance spectrometer may include a doped nanostructured crystal. By nanostructuring the surface of the crystal, the sensor-sample contact area of the crystal can be increased. As a result of the increased sensor-sample contact area, the output fluorescence signal emitted from the crystal is also increased, with corresponding reductions in measurement acquisition time and requisite sample volumes.
