Abstract: A frameless, portable, layout hunting blind for use by a sitting or reclining hunter has a frameless floor, an enclosed foot and leg sack for the hunter's legs, a movable flap to cover the hunter's upper body, a collapsible foot sack support to keep the foot sack clear of the hunter's legs, and an air-inflatable head and shoulder rest.

Abstract: An improved method and capacitance probe arrangement for determining the fluid phase fractions of fluids having differing permitivity such as those of gas, oil, and water and oil-water emulsion in a fluid stream flowing from an oil well which includes trapping the primarily liquid in a vertically disposed chamber. The liquid is held therein to permit separation of the phase fractions to the extent possible within a reasonable time. A number of measurements are taken of the capacitance at a plurality of discrete vertically spaced locations within the chamber. These capacitance measurements relate directly to the varying permittivity of the phase fractions of the various liquids contained therein which may be gas, oil, and water and a oil-water emulsion. The measurements are processed by a data processor to provide precise information on such phase fractions and emulsion interfaces. A number of embodiments of the novel probe are disclosed for determining capacitance at spaced locations within the chamber.
