    摘要： A self-regulating bubble tube assembly is used for determining the hydrostatic pressure exerted by fluids, such as drilling mud. The bubble tube assembly can be used to determine fluid level based upon said hydrostatic pressure and when bubble tubes are used in pairs can be used to determine a pressure differential that will indicate the density of the fluid. The bubble tube assembly comprises a flow of air directed through a diaphragm type pressure regulator. The pressure regulator output is connected to the bubble tube, which is partially submerged in the fluid, through a precision, in-line, flow limiting orifice. A feedback line from the bubble tube runs to one side of the diaphragm of the pressure regulator where the back pressure from the tube will regulate the output pressure from the regulator to maintain a pre-selected constant rate of air flow through the bubble tube. Hydrostatic pressure exerted by the liquid is measured from a line leading from the bubble tube to a pressure sensitive meter or the like.

    摘要： An apparatus and method for training animals has active and passive components. The animal is trained to avoid entering an area by a mild shock which the animal received when it treads on a visible interdigital array. Eventually the animal is deterred by viewing the array alone and the shocking means is removed. The visible array can be supplemented with electroluminescent, olfactory or audio stimuli.
