Abstract: ABSTRACT OF THE DISCLOSURE            Ammonium orthophosphate products are prepared by reacting ammonia and phosphoric acid together at high speed under vigorous mixing conditions by spraying the reactants through a two-phase, dual coaxial mixer/ sprayer and separately controlling the supply and axial outflow rate of the phosphoric acid at 1 to 10 m/sec. and the outflow rate of ammonia at 200 to 1000 m/sec. (N,T.P.). Thorough mixing and a homogeneous product is obtained by directing the outflow spray into a coaxial cylindrical reaction chamber of a specified size with respect to the diameter of the outer most duct of the sprayer/mixer.  The product may be granulated on a mov-ing bed of granules and adjusted in respect of the NH3 to H3PO4 content by changing the concentration of the phosphoric acid and/or supplying additional ammonia to the granulation bed.

A second reservoir is connected to a natural reser-voir such as the ocean by means of a duct system wherein the duct openings in the two reservoirs are established at levels which will constantly be submerged.  Upon charging the duct system with water, the siphon principle will urge the flow of water back and forth through the duct system between the two reservoirs as the water in the second reservoir seeks a level of equilibrium with that of the ocean.  A turbine is mounted in the duct system and is driven by the substantially continuous flow of water back and forth through the system thereby producing a source of useable energy.

Abstract: ROTATIONAL VISCOMETER          Abstract of the Disclosure A microprocessor controlled rotating-cylinder viscometer for measuring the shear stress at a given shear rate of a fluid is disclosed.  The fluid is contained between a rotatable outer cylinder and a rotatable inner cylinder.  The inner cylinder rotates in response to the torque produced by rotation of the outer cylinder in the fluid.  The amount of rotation of the inner cylinder is related to the shear stress of the fluid.  A fast slewing accurate motor speed control is provided for maintaining rotation of the outer cylinder at the selected shear rates. An absolute value shaft encoder monitors the amount of rotation of the inner cylinder to obtain the shear stress readings.  The steady state value of the shear stress is obtained by averaging a predetermined number of measurements taken over a sample interval to obtain a stress reading. Consecutive readings are compared until the difference between readings in less than ? 1°, the current shear stress then taken on the steady state value.
