Abstract: An air gun intended for use in generating seismic energy impulses, i.e. acoustical waves, in a body of water that provides improved performance by adjusting the length of the firing chamber in order to tune the rise time from zero pressure to peak pressure and to increase or decrease the slope of the initial pulse. By selecting the length of the firing chamber, the rise time of the initial pulse is tuned to increase low frequencies and reduce objectionable high frequencies to help in mitigating damage to marine life and the marine environment and to provide greater penetration of the seismic signal through for example basalt and sub-basalt structures.

Abstract: A sound source for geophysical studies of the earth for oil, gas and other natural resource exploration and more specifically a streamlined design of a hydraulically controlled impulsive sound source that may be inserted into oil wells and bore holes and a system and method for obtaining high quality seismic records from the impulsive sound source by adjusting and maintaining pressures within the well or bore hole.

Abstract: A marine vibratory sound source for producing swept or pulse coded signals in a body of water and within geological structures beneath a body of water, primarily for seismic exploration of the strata beneath the bottom of the water. More particularly, a high power, servo controlled hydraulic, sound source that delivers fluid alternatively to first and second actuator pistons to move the actuator pistons to a forward and an aft position thereby axially vibrating a piston shaft having cone-shaped pistons for vibrationally moving water out and in through a plurality of ports for propagating vibratory sound. The sound source having a position sensor to determine a center point of travel and by tracking the position sensor air pressure in hollow stationary cone-shaped bulkheads is modulated to maintain the travel of the cone-shaped pistons at an equal distance in the fore and aft directions from the determined center point.

Abstract: A repeatable water gun device for projecting jets of water into ambient surrounding water for the purpose of causing cavitations in the water which when the produced cavities collapse due to ambient water pressure a loud sharp report is caused when the cavities collapse upon themselves. The sharp reports may be used for scaring fish away from the intakes of water pipe lines, for cleaning water wells, and for the removal of zebra mussels or other sea life infestation from water pipes.

More particularly, a high power, servo controlled hydraulic, sound source that can readily be towed in water, towed along the bottom surface under the water or be used in a stationary position on the bottom surface under the water.

Abstract: The device hereof is most preferably the use of the slime coating of slugs or a synthetic copy of the slug slime, healing agents such as steroids antibiotics, growth hormones or pain killers can be mixed is with the slime before application to a burned or infected area. The slime thusly becomes a carrier for the medicines to the affected area as an antibiotic or anti fungal agent. Also, the same material can be used to protect and promote the healing of burns, due to its unique properties, of not only being hydroscopic and/or water absorbing, but also being non water soluble, as well as for its anti-infection properties. Another potentially helpful property of this material, is that it forms a protective skin-like membrane when spread over an area of skin and the observed condition was over burned skin.

Abstract: 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.

Abstract: A method for making artificial snow using micro particulate material for the performance enhancement of snow making equipment, wherein very small particles of material are mixed into the water supply system which supplies water to the snow making guns at a skiing area. The particles serve as the nucleus for snow crystals to grow upon when sprayed into the atmosphere by the snow making guns. The water, which has the nucleating material mixed into it, is sprayed out of the snow making guns in the form of fine droplets, small enough for the cold ambient air at the skiing slope to freeze the small water droplets into the solid form of snow flakes. The nucleating material, which originally is in the form of a fine powder, may be mixed in a suitable container with a portion of the water, so it can be appropriately metered through a pump, into the water pipe that feeds the snow making guns.

Abstract: A linear vibratory pile driver apparatus, system and method for using the apparatus to drive or to pull pilings. The apparatus is comprised of a lifting shaft isolated from but slideably mounted within a piston assembly which piston assembly is attached to a frame assembly. There is a cylinder assembly attached to a reaction mass and the piston assembly is vibratorily positioned within the cylinder assembly and vibratorily driven by hydraulic fluid at a selectable frequency thereby vibrating the piston/frame assembly (the piston assembly and the attached frame assembly) relative to the cylinder/reaction mass assembly (the cylinder assembly and the attached reaction mass). A clamp device such as jaws is attachable to a clamp-end of the frame assembly and the lifting shaft is attachable to a cable of a lifting apparatus such as a crane.

Abstract: For marine seismic surveying using an array of airguns towed behind a survey ship, wherein a common high pressure hoseline supplies compressed air to a multitude of airguns, a method, system and apparatus selectively shut off air flow to any airgun for stopping leakage of compressed air from the common supply line. Shutoff valves are employed with a respective valve being upstream of each airgun to enable selectively shutting off compressed air flow from the common supply line to any airgun for stopping loss of compressed air from the common line caused by leakage from a leaking component downstream from any valve, such as a ruptured feeder hoseline to an airgun. Each shutoff valve has a spring whose spring force biases open its valve. Simultaneous electrical energization of windings in all shutoff valves electromagnetically overcomes the spring force for simultaneously closing all valves.
