Abstract: A non-destructive test using cryogenic temperatures is capable of detecting defects in materials that result from residual stress from manufacturing and from retained austenite. The subject materials or parts that are subjected to cryogenic temperatures approaching and below˜−300° F., −184° C., 89° K, thereby causing permanent deformations or characteristic changes in the material if excessive residual stress, retained austenite or discontinuities exist. To determine the extent of changes, a first metric of the subject material is determined, the material is then subjected to cryogenic cooling thereby triggering any deformation or characteristic changes. Subsequent to the cryogenic cooling, the subject material may be returned to a second temperature whereby a second metric representing based on the same characteristic of the subject material is determined The comparison of the first and second metrics reveals the deformation or change resultant from the defect. In addition characteristic changes in the subject material during cryogenic cooling may be use to detect the phase transition of the retained austenite to martensite.

Abstract: A method for measuring the deformation of elastomeric materials using acoustic signals involves obtaining a sample, positioning the sample in a sealable chamber, sealing the chamber, and setting a temperature and pressure inside the chamber. A test fluid may be introduced to the chamber. An acoustic signal is used to measure a characteristic of the sample, such as a dimension or a modulus. Repeated measurements may be made overtime to monitor changes in the sample in response to temperature and pressure. The acoustic signal may be generated by an acoustic transducer including a backing component including a fluorine-containing polymer in which metal particles are incorporated. The sample may be a non-metallic material. Conditions inside the chamber may be set to simulate a wellbore environment.

Abstract: The invention relates to a method for checking the state of a pipette, which pipette includes a suction tube and a pipette tip. According to the invention, ultrasound is coupled into the wall of the suction tube and the damping of the ultrasonic signal is measured as a function of the frequency. The measured frequency-dependent damping is compared with at least one reference measurement or a calibration curve based on the reference measurements, in order to determine whether the pipette is in a functional condition and/or whether the pipette contains or has made contact with fluid. Furthermore, the invention relates to a pipetting method which uses the inventive method for checking the state, a suction tube arrangement for a pipetting device for pipetting fluid, and a pipetting device with which the inventive methods can be carried out.
