Abstract: The invention provides caverns and methods for producing caverns in bedded salt deposits. In a preferred method, a first bore hole (19) is drilled into the salt formation (10) and a cavity (13) for receiving insolubles is leached from the salt formation (10). Thereafter, at a predetermined distance away from the first bore hole (19), a second hole (17) is drilled towards the salt formation. The drill drills through the salt formation in a horizontal direction until it instersects the cavity (13) for receiving insolubles. This produces a substantially horizontal conduit (20) from which solvent is controlledly supplied to the surrounding salt formation, leaching the salt and producing a concentrated brine which is removed through the first bore hole (19). Insoluble are collected in the cavity (13) for receiving insolubles. By controlledly supplying solvent, a horizontal cavern is produced with two bore holes (17 and 19) extending therefrom.

Abstract: With the crude instrumentation now in use to continuously monitor the status of the fetus at delivery, the obstetrician and labor room staff not only over-recognize the possibility of fetal distress with the resultant rise in operative deliveries, but at times do not identify fetal distress which may result in preventable fetal neurological harm. The invention, which addresses these two basic problems, comprises a method and apparatus for non-invasive determination of blood oxygen saturation in the fetus. The apparatus includes a multiple frequency light source which is coupled to an optical fiber. The output of the fiber is used to illuminate blood containing tissue of the fetus. In the preferred embodiment, the reflected light is transmitted back to the apparatus where the light intensities are simultaneously detected at multiple frequencies. The resulting spectrum is then analyzed for determination of oxygen saturation. The analysis method uses multivariate calibration techniques that compensate for nonlinear spectral response, model interfering spectral responses and detect outlier data with high sensitivity.
