An autonomous unmanned underwater vehicle (“AUV”) includes a body, a controller, a buoyancy engine, a rotary propulsion system and pitch control surface(s). The buoyancy engine is for alternately ingesting and expelling ambient water to change the mass of the AUV and thereby cause the AUV to alternately descend and ascend in the water. The pitch control surface(s) are for causing the AUV to move forward while alternately descending and ascending in the water. The rotary propulsion system includes a motor for rotating a propeller in the water to provide thrust. The controller is operative for responsively, automatically switching between at least the glider and rotary propulsion modes. In the glider mode, the buoyancy engine and the pitch control surface(s) are cooperative for causing the AUV to move forward while alternately descending and ascending. In the rotary propulsion mode, the rotary propulsion system is operative for causing the AUV to move forward.

Streamlined, towable, marine seismic energy vibrator for creating intense swept-frequency and pulse-coded seismic signals in a body of water has a sleek, fish-like configuration designed for towing with minimum drag. The vibrator has a streamlined hollow towing head and a streamlined hollow tail head mounted onto front and rear of a long cylindrical tubular wall which is modular, comprising cylinder sections joined in end-to-end axial alignment. Within this long tubular cylinder wall is an axially vibratable multi-piston assembly having a plurality of pistons on a long piston rod. One piston is positioned in each of the cylinder chambers. These chambers hive multiple ports opening out through the long cylindrical wall. An elongated circular cylindrical elastomeric bladder forms a water-filled bladder chamber encircling the wall.

A method of and apparatus for controlling drainage/irrigation of a field includes laying out a network of drainage tiles, which typically may include a main line and a number of lateral lines, extending from higher elevations to lower elevations and exiting through a manually controlled main valve to a drainage ditch.

A series of level-responsive valves are incorporated in the main and lateral lines at selected elevations. Each level-responsive valve is normally open until the ambient water level reaches a predetermined level relative to the valve. When the manual valve is closed and a certain level of water is reached adjacent a level-responsive valve, it causes that level-responsive valve to close, thereby cutting off drainage of higher elevations. When it is desired to retain water at higher elevations in a field, the manual valve is closed permitting water to accumulate and be retained at higher elevations by closing the level-responsive valves in sequence at progressively higher elevations as the level of retained water rises, thereby causing a cascading or “terracing” of water stored at upper levels. When the manual valve is opened, the field drains normally. The level-responsive valve may be a flotation valve. A modification of a flotation type level-responsive valve includes an overflow tube which permits excessive water at higher placement elevations to bypass the closed level-responsive valves, thereby permitting the field to drain under conditions of excess water into a standpipe at the manual valve.

An apparatus for inhibiting the formation of tropical cyclones, comprising an elongated rigid tube through which cooler water is pumped from below to the near-ocean surface, thereby depriving incipient tropical cyclones of the heat energy they require for further development. The tube contains a pump comprising a fixed flap valve and a movable flap valve. The movable flap valve is attached to a drive disk encircling the tube at a depth where ambient waters have little vertical motion. The wave-driven vertical motion of the elongated tube causes the movable flap valve to oscillate with respect to the fixed flap valve, thereby pumping seawater upward onto the near-ocean surface. The apparatus also can navigate to alternative locations by means of a propulsion/steering system, and it can submerge to a safe depth to avoid oncoming vessels and potentially damaging seas. A fleet of apparatuses is required to provide the necessary cooling effect.
