Autonomous unmanned underwater vehicle with buoyancy engine
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, readily towable marine seismic energy source for creating intense swept-frequency and pulse-coded signals in a body of water
InactiveUS6464035B1Easy to manufactureIncrease surface areaSeismic energy generationSeismology for water-covered areasAmbient waterConfiguration design
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. An actuator piston is vibrated by a remotely controllably hydraulic circuit, thereby vibrating the multi-piston assembly for vibrating water out and in through multiple ports communicating with the water-filled bladder chamber for vibrating the exterior of the bladder shown having diameter "D" of 18 inches and length "L" of 118.5 inches, providing a 6,700 square inch vibration area contacting the ambient water. A multi-piston position sensor enables synchronization of the vibrator with companion sources being towed. An axial passage in the long piston rod feeds low-pressure compressed air into the cylinder chambers forming air cushions behind the pistons vibrating water in these cylinder chambers.

A swim and skin-dive snorkel for providing positive end-expiratory pressure for pressure-balanced exhalation.The snorkel may include inhalation and exhalation conduits. Air can be exhaled into a chamber and released when exhalation pressure within the chamber exceeds a threshold pressure. The threshold pressure that must be overcome to achieve exhalation may be balanced against the compressive forces of the ambient water pressure acting against the user's chest and lungs, which may greatly reduce the resting expiratory flow rate, the minute respiratory rate, and therefore the overall work of breathing. The exhalation pressure may be linearly matched to the ambient water pressure as a function of dive depth, thereby discouraging exhalation while diving. A purge valve may also be placed at the lower aspect of the snorkel.

Method and apparatus for controlling drainage and irrigation of fields
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.
